Mitsubishi Outlander Low Washer Fluid Reset: Complete Guide

A Mitsubishi Outlander low washer fluid reset should be one of the simplest jobs we perform on the vehicle. We refill the reservoir, start the engine, and expect the message to disappear. Most of the time, that is exactly what happens.
Sometimes, however, the warning stays on like an unwanted dashboard guest.
The reservoir may be full. The windshield washers may spray normally. There may be no obvious leak anywhere. Yet the instrument panel continues to announce that the washer fluid is low.
What is going on?
The most important thing to understand is that most Mitsubishi Outlander models do not have a special button combination for resetting the low washer fluid warning. The system normally resets itself after the reservoir has been filled and the level sensor detects enough fluid. When the message remains, we are usually dealing with trapped air, a sticky float, unsuitable fluid, damaged wiring, or a faulty level sensor rather than a forgotten reset procedure.
In this guide, we will explain how the system works, how to refill it correctly, what to do when the warning refuses to disappear, and how to diagnose the problem without replacing random parts.

In most Mitsubishi Outlander versions equipped with a washer-level warning, there is no dedicated washer fluid reset button.
We normally do not need to enter a dashboard menu, hold the trip switch, disconnect the battery, or use an automotive scanner. The warning should clear automatically when the level sensor recognizes that enough washer fluid is inside the reservoir.
That makes the normal reset process refreshingly simple:
- Park the Outlander safely.
- Switch the engine off.
- Open the hood.
- Locate the washer fluid reservoir.
- Fill it with suitable windshield washer fluid.
- Close the reservoir cap.
- Restart the vehicle.
- Allow the system a moment to update.
If the reservoir was genuinely low and the sensor is functioning correctly, the message should disappear.
Some Outlander manuals instruct owners to inspect the washer-fluid level visually or with the reservoir dipstick, depending on the vehicle’s design. Mitsubishi also advises using washer fluid containing an antifreezing agent in cold conditions rather than treating the reservoir like an ordinary water container.
What the Low Washer Fluid Warning Means
The message is not measuring the fluid with laboratory precision. It is simply reporting that the fluid has dropped below the level recognized by the reservoir sensor.
On equipped models, a float or level switch sits in or near the washer reservoir. As the fluid falls, the float changes position. The switch then sends a signal to the instrument cluster, which displays the warning.
Think of it like a tiny buoy inside a harbor. When the water is high, the buoy rises. When the level drops, it sinks and triggers the alert.
The system does not calculate:
- How many ounces or liters remain
- How many washer sprays are available
- Whether the fluid is clean
- Whether the washer nozzles are blocked
- Whether the pump is working correctly
It only detects the fluid level around a specific point.
This distinction matters because a full-looking reservoir can still produce a warning if the float is stuck, the sensor connector is damaged, or the fluid does not move freely around the sensor.
Does Every Mitsubishi Outlander Have the Warning?
Not necessarily.
Features can differ by:
- Model year
- Trim level
- Country
- Gasoline or PHEV configuration
- Instrument-cluster design
- Cold-weather equipment package
- Headlamp washer availability
Some Outlanders require the driver to check the reservoir manually and may not display a low-level warning at all. Older manuals commonly describe opening the cap and checking the level visually or with a dipstick. The reservoir may serve the windshield, rear window, and headlamp washers when those systems are fitted.
Therefore, we should not assume that every Outlander uses the same reservoir, sensor, warning message, or electrical layout.
The safest reference is always the owner’s manual for the exact model year and market.
How to Perform a Mitsubishi Outlander Low Washer Fluid Reset
Let us begin with the standard procedure. This method handles the majority of genuine low-fluid warnings.
Step 1: Park on Level Ground
Place the vehicle on a reasonably flat surface and apply the parking brake.
Why does level ground matter?
A low reservoir can produce inconsistent readings when the vehicle is leaning on a steep driveway. Fluid may move away from the sensor, making the system believe the tank is emptier than it really is.
Parking level also gives us a more accurate visual reading when we open the reservoir.
Step 2: Turn the Vehicle Off
Switch the ignition off before working around the engine compartment.
The washer reservoir is not normally a dangerous component, but turning the vehicle off reduces the chance of moving parts, unexpected electrical activity, or somebody operating the washers while the cap is open.
On a PHEV, make sure the vehicle is fully switched off rather than merely silent in its ready-to-drive state.
Step 3: Open the Hood
Release the hood from inside the cabin, then use the secondary latch at the front.
Secure the hood using the support rod if the model is not fitted with gas struts.
Step 4: Locate the Washer Fluid Reservoir
Look for a translucent plastic reservoir or filler neck with a cap showing a windshield-and-spray symbol.
Do not confuse it with the:
- Engine coolant reservoir
- Brake fluid reservoir
- Power-steering reservoir on older vehicles
- PHEV cooling-system tanks
- Engine-oil filler cap
The washer cap is often blue, black, or another visible color, but color alone is not a reliable identification method. Look for the windshield washer symbol.
Step 5: Inspect the Existing Fluid Level
If the container is visible, check how much fluid remains. On some designs, we may need to use the dipstick attached to the cap or look down the filler neck.
If the reservoir appears completely empty, inspect the ground beneath the front of the vehicle before filling it. A puddle may reveal a split tank, loose hose, or leaking pump seal.
Step 6: Add the Correct Washer Fluid
Pour proper windshield washer fluid into the reservoir slowly.
Avoid filling too aggressively. A narrow filler neck can trap air, causing the fluid to back up near the opening before the lower reservoir is actually full.
Pause occasionally and allow the liquid to settle.
Fill until the reservoir reaches its indicated full level or until the fluid sits at the appropriate point specified in the owner’s manual. Do not deliberately force extra liquid into an already full container.
Step 7: Reinstall the Cap
Push or twist the cap into its proper closed position.
A loose washer-fluid cap will not usually create the low-level warning because the reservoir is not a pressurized system. Still, closing it protects the fluid from dirt, leaves, and engine-compartment debris.
Step 8: Restart the Outlander
Start the vehicle and observe the instrument cluster.
The warning may disappear immediately. On some vehicles, the cluster may need several seconds to receive and process the new sensor signal.
Step 9: Operate the Washers Briefly
Spray the windshield washers for a second or two.
This confirms that:
- The pump operates
- Fluid reaches the nozzles
- The hoses are connected
- The reservoir contains usable fluid
Do not hold the washer switch continuously for a long period. A dry or obstructed pump can overheat.
Step 10: Switch the Ignition Off and Back On
If the message remains, turn the vehicle off, wait roughly 30 seconds, and restart it.
This is not a secret reset sequence. It simply gives the instrument cluster another opportunity to read the level-switch status during a fresh ignition cycle.
How Long Should the Warning Take to Clear?
A properly functioning system will usually clear the warning either immediately after refilling or during the next ignition cycle.
There is no reason to drive hundreds of miles hoping the vehicle eventually forgets the message. The washer warning is generally based on a direct level-switch signal rather than a maintenance-distance counter.
A brief delay can occur when:
- Fluid is still moving inside the tank
- The float needs time to rise
- The vehicle is parked on a slope
- Air is trapped around the sensor
- The cluster has not refreshed its input
If the warning remains after the reservoir has been filled, the vehicle has been placed on level ground, and the ignition has been cycled, we should begin troubleshooting.
Why the Warning Stays On After Refilling
A persistent warning is frustrating, but the possible causes form a fairly logical chain.
The Reservoir Is Not Actually Full
This sounds obvious, yet it happens frequently.
The filler neck may appear full while a large air pocket prevents fluid from reaching the lower reservoir. After a few moments, the level near the cap drops as the fluid settles.
Add washer fluid slowly, pause, and check again.
Some tanks have unusual shapes that wrap around bodywork or sit partly behind the bumper. The visible filler neck may represent only a small portion of the entire reservoir.
The Vehicle Is Parked at an Angle
When the tank is close to the warning threshold, even a modest slope can move the fluid away from the sensor.
Park on level ground, wait for the fluid to settle, and restart the vehicle.

The Float Is Stuck
A float can remain in the low position because of:
- Dirt
- Wax-like residue
- Mineral deposits
- Old concentrated fluid
- Sludge
- Ice
- Internal sensor wear
Imagine a fishing bobber glued to the bottom of a bucket. We can add water all day, but the bobber will not rise until it breaks free.
Gentle movement of the reservoir may release a sticky float, but we should never hit the tank hard. Plastic becomes brittle with age and cold temperatures.
The Fluid Is Frozen or Slushy
Plain water and weak summer washer mixtures can freeze in cold weather.
When the reservoir freezes, the float may be trapped in the low position. The pump, hoses, and nozzles may also freeze.
Mitsubishi’s maintenance guidance recommends washer fluid containing an antifreezing agent in low temperatures.
Move the vehicle into a warm environment and allow the system to thaw naturally. Do not pour boiling water over the tank. Sudden temperature changes can crack plastic parts.
After thawing, replace the diluted mixture with fluid rated for the expected temperature.
The Washer Fluid Is Producing Residue
Not every blue liquid sold near automotive products behaves the same way.
Some homemade mixtures, concentrated additives, water-repellent products, or incompatible fluids can leave deposits around the level sensor. Tap water may also introduce minerals, particularly in hard-water regions.
A contaminated sensor may react slowly or remain stuck.
The Level Sensor Has Failed
The washer level sensor is a simple component, but simple components still wear out.
An internal switch may become permanently open or closed. A float may absorb fluid, detach, crack, or lose its ability to move. Corrosion can also develop around the sensor terminals.
Reports involving persistent warnings on certain Outlanders commonly point toward the reservoir level sensor or its electrical connection once the reservoir has been confirmed full.
A failed sensor often produces these symptoms:
- The warning remains with a full tank
- The washers operate normally
- No visible leak is present
- The warning does not change when fluid is added
- The message returns immediately after startup
The Electrical Connector Is Loose
The sensor needs a stable electrical connection to communicate with the instrument cluster.
A loose plug, damaged locking tab, corroded terminal, or broken wire can imitate an empty reservoir.
The connector may be difficult to access because the tank often sits low behind the bumper or inner fender liner. We should avoid pulling on wires blindly.
The Wiring Is Damaged
Road debris, moisture, previous collision repairs, rodents, or careless bumper work can damage the sensor wiring.
Common wiring problems include:
- Chafed insulation
- Pinched harnesses
- Broken conductors
- Corroded terminals
- Poor ground connections
- Incorrectly repaired wires
The warning can appear constantly or intermittently depending on how the damaged wire moves.
The Reservoir Is Leaking
A tank can accept fluid and appear full, only to lose it over the next few minutes or hours.
Potential leak points include:
- Cracked reservoir seams
- Washer pump grommets
- Level sensor seals
- Filler neck connections
- Front washer hoses
- Rear washer hoses
- Headlamp washer lines
- Pump housing
A slow leak may leave little more than a damp patch. A major leak may create a visible puddle beneath the front bumper.
The Instrument Cluster Has Not Updated
Cluster problems are possible, but they are much less common than low fluid, a stuck float, a sensor failure, or damaged wiring.
We should inspect the basic system before blaming the dashboard electronics.
Safe Troubleshooting Order
A structured diagnosis saves time and keeps us from firing the parts cannon.
First-Level Checks
Start with the simplest items:
- Confirm the correct reservoir was filled.
- Park the vehicle on level ground.
- Verify the reservoir is genuinely full.
- Check for fluid beneath the vehicle.
- Operate the front and rear washers.
- Cycle the ignition.
- Allow frozen fluid to thaw if necessary.
If the warning disappears, no further action is required.
Second-Level Checks
When the warning remains:
- Inspect the fluid for contamination.
- Look for damage around the filler neck.
- Check whether the tank level drops over time.
- Examine accessible hoses.
- Inspect accessible wiring and connectors.
- Look for corrosion near the reservoir sensor.
Do not crawl beneath an unsupported vehicle. Use proper lifting equipment and safe working procedures whenever underbody access is required.
Third-Level Diagnosis
A technician can test:
- Level-switch continuity
- Sensor resistance, where applicable
- Connector voltage
- Ground integrity
- Harness continuity
- Instrument-cluster inputs
- Relevant diagnostic trouble codes
Not every washer-level fault will create a standard check-engine code. A basic engine-code reader may therefore show nothing even though the warning remains active.
Can We Reset the Warning by Disconnecting the Battery?
Disconnecting the battery is usually unnecessary and may not solve the underlying issue.
The warning will return as soon as the cluster again receives a low-level signal from a stuck sensor or damaged circuit.
Battery disconnection may also cause the vehicle to lose or temporarily relearn settings such as:
- Clock information
- Window initialization
- Radio presets
- Idle characteristics
- Driver preferences
- Certain electronic-system values
On newer models and PHEVs, casually disconnecting electrical power is an especially poor substitute for diagnosis.
A battery reset is like silencing a smoke alarm while leaving the smoke in the room. The dashboard may briefly become quiet, but the cause remains.
Can an OBD Scanner Clear the Washer Fluid Message?
Usually, no scanner-based reset is required.
A scan tool can be useful if the body control system or combination meter has stored a related fault. However, clearing a code will not repair:
- A stuck float
- A defective level switch
- A broken wire
- A leaking reservoir
- A corroded connector
The warning should clear naturally when the sensor circuit reports the correct fluid level.
A professional diagnostic scanner may help us observe live switch data. For example, a technician may be able to see whether the vehicle reports the switch as “low” even when the tank is full. That information can separate a sensor-side problem from a display-side problem.
Should We Tap the Washer Reservoir?
A very gentle tap may free a stuck float, but this should never become hammer therapy.
Reservoir plastic can crack, particularly when:
- The vehicle is old
- The weather is cold
- The tank has been exposed to chemicals
- The plastic has become brittle
- The reservoir is firmly trapped against bodywork
Use the palm of the hand and minimal force only when the accessible tank wall is clearly identifiable.
Never strike:
- The washer pump
- Electrical connectors
- Nearby cooling-system tanks
- PHEV electrical components
- Metal tools against the reservoir
If a gentle movement clears the warning but the problem returns, the sensor is probably sticking and may require cleaning or replacement.
How to Clean a Contaminated Washer Reservoir
Cleaning may help when the fluid contains sludge, debris, or incompatible additives.
Basic Cleaning Procedure
Depending on access and vehicle design, we can:
- Remove as much old fluid as possible using a suitable hand pump.
- Add a small amount of appropriate clean washer fluid.
- Agitate the reservoir gently.
- Remove the rinse fluid.
- Refill with fresh, compatible washer fluid.
- Test the warning and washer operation.
Avoid pouring household cleaners into the tank. Soap can foam excessively, leave residue, damage components, or create a smeared windshield.
When Reservoir Removal Is Better
If contamination is severe, the tank may need to be removed for proper cleaning.
Removal can involve:
- Wheel removal
- Inner fender liner removal
- Lower splash-shield removal
- Bumper loosening or removal
- Pump disconnection
- Sensor disconnection
- Hose removal
The exact procedure varies substantially by model year. A workshop manual is preferable to guesswork.
Washer Fluid Sensor Replacement
When testing confirms a defective level sensor, replacement is usually the proper repair.
On some vehicles, the sensor can be replaced separately. On others, the sensor design, seal availability, or parts catalog may make reservoir replacement more practical.
Typical Replacement Steps
The general process may include:
- Disconnecting the 12-volt battery when specified.
- Raising and safely supporting the vehicle.
- Removing the wheel or splash liner.
- Draining the washer fluid.
- Disconnecting the sensor connector.
- Removing the old sensor.
- Installing a new seal or grommet.
- Installing the replacement sensor.
- Reconnecting the wiring.
- Refilling the reservoir.
- Checking for leaks.
- Confirming that the warning clears.
This outline is not a substitute for the exact repair procedure. Fastener locations and access routes differ among Outlander generations.
Why the Sensor Seal Matters
A reused or damaged grommet can create a leak after the new sensor is installed.
The repair may appear successful because the warning disappears initially, only to return when the reservoir slowly drains.
Always inspect the sealing surface and use the correct replacement seal where required.

Where to Find Reliable Fiat Repair Services Near MeShould We Bypass the Washer Level Sensor?
Bypassing the circuit is not recommended as a proper repair.
Cutting wires, joining terminals without confirming the circuit design, or permanently disabling the warning can create several problems:
- Loss of the low-fluid safety reminder
- Short circuits
- Harness damage
- Incorrect cluster signals
- Future diagnostic confusion
- Reduced resale confidence
- Electrical problems after moisture intrusion
Online discussions sometimes describe owners cutting or modifying sensor wiring to eliminate persistent warnings, but those anecdotes do not make the method safe or technically correct.
Repair the sensor or wiring instead of hiding the symptom.
What If the Washers Do Not Spray?
A low-fluid warning and nonworking washers may be related, but they are not the same problem.
If the tank is full and nothing sprays, investigate:
- Frozen fluid
- Blocked nozzles
- Disconnected hoses
- Split hoses
- Failed washer pump
- Blown fuse
- Damaged switch
- Electrical connector problems
- Empty sections of the system after repair
Listen for the Pump
With the ignition in the appropriate position, operate the washer control briefly.
If we hear the pump:
- The fuse and switch may be functioning.
- A hose may be disconnected.
- A nozzle may be blocked.
- The fluid may be frozen.
- The pump impeller may be damaged.
If we hear nothing:
- The pump may have failed.
- The fuse may be open.
- The switch circuit may have a problem.
- The pump connector may be disconnected.
- The system may not be receiving power.
Remember that the front and rear washers may use different pump directions, outlets, or separate circuits depending on the design.
Does a Faulty Washer Sensor Affect Driving?
A washer-level sensor failure will not normally prevent the Outlander from starting, shifting, steering, or driving.
However, we should not ignore the washer system indefinitely.
A clean windshield is essential during:
- Heavy rain
- Winter road-salt exposure
- Dusty driving
- Muddy conditions
- Insect-heavy summer travel
- Night driving with glare
- Long highway journeys
The warning itself may be minor, but an empty or inoperative washer system can quickly become a visibility problem.
Can the Warning Cause an Inspection Failure?
Inspection rules vary by country, state, province, and testing program.
In many locations, inspectors care more about whether the windshield washer system works than whether the low-fluid message is displayed. In others, an active dashboard warning or defective washer system may affect the result.
Because regulations change, confirm the current requirements in the location where the vehicle is registered.
Regardless of inspection rules, repairing the system is worthwhile. A persistent dashboard message can also conceal a future genuine low-fluid condition because we become accustomed to ignoring it.
Choosing the Right Washer Fluid
The best washer fluid depends on climate and driving conditions.
Warm-Weather Fluid
A standard cleaning fluid may be suitable in regions where freezing temperatures do not occur.
Look for a product designed for automotive washer systems rather than household glass cleaner.
Cold-Weather Fluid
Use a formula rated below the lowest temperature the vehicle is likely to encounter.
A winter-grade fluid helps protect:
- The reservoir
- Pump
- Hoses
- Nozzles
- Level sensor
- Headlamp washers, if fitted
Bug-Removing Fluid
Summer formulas may provide stronger cleaning against insect residue. Confirm that the product is compatible with vehicle paint, plastic, rubber, and washer-system components.
Water-Repellent Formulas
Some fluids leave a water-repellent coating on the glass. They can work well, but mixing several chemical formulas may create residue.
When changing product types, avoid combining a large amount of old fluid with a different concentrated formula.
Can We Use Plain Water?
Plain water may seem harmless, particularly in warm climates, but it has disadvantages.
It can:
- Freeze in cold weather
- Encourage biological growth
- Leave mineral deposits
- Clean poorly against oil and road film
- Create scale around the sensor and pump
- Produce unpleasant odors over time
In an emergency, a small amount of clean water may restore temporary washer operation in above-freezing conditions. For regular use, proper automotive washer fluid is the better choice.
Never use radiator antifreeze in the washer reservoir. Windshield washer antifreeze and engine coolant are entirely different products.
Preventing Future Low Washer Fluid Warnings
A little routine attention prevents most washer-system surprises.
Check the Reservoir Monthly
We do not need to wait for a warning. Inspect the level during regular under-hood checks.
Top It Up Before Long Trips
Fill the reservoir before:
- Road trips
- Winter travel
- Mountain driving
- Dusty rural journeys
- Long periods of highway driving
Use Climate-Appropriate Fluid
Switch to winter-rated fluid before freezing weather arrives rather than after the reservoir has turned into a block of ice.
Avoid Mixing Unknown Products
Combining several additives can create cloudiness, deposits, or unexpected chemical reactions.
Repair Small Leaks Early
A minor damp spot around the pump seal can become a completely empty reservoir later.
Keep the Filler Cap Closed
An open cap allows dirt and debris into the tank. Contamination can clog the pump screen, nozzles, and sensor mechanism.
Common Mistakes During a Washer Fluid Reset
Even simple maintenance has a few traps.
Filling the Wrong Reservoir
Confusing washer fluid with coolant can cause expensive damage. Always verify the symbol on the cap.
Assuming the Filler Neck Is the Entire Tank
Fluid may need time to flow into the lower section.
Using Boiling Water to Melt Ice
Rapid heating can crack the reservoir or damage surrounding components.
Replacing the Pump Instead of Testing the Sensor
The pump sprays fluid. The level sensor controls the warning. One can work perfectly while the other fails.
Clearing Codes Without Repairing the Cause
A reset cannot unstick a float or repair a broken wire.
Cutting the Sensor Wiring
This may remove the message while creating a permanent electrical modification.
Overfilling the Reservoir
Adding fluid beyond the intended level can cause spills and unnecessary mess. Fill to the specified point rather than forcing in every possible drop.
Mitsubishi Outlander vs. Outlander Sport Washer Systems
The Mitsubishi Outlander and Outlander Sport are separate vehicles, even though their names sound closely related.
The Outlander Sport is also known as the ASX or RVR in some markets. Its reservoir location, capacity, sensor design, and access procedure may differ from those of the larger Outlander.
Do not purchase a sensor, reservoir, pump, or grommet based only on the word “Outlander.”
Confirm:
- Full vehicle name
- Model year
- Market
- VIN
- Engine
- Trim
- Part number
The same caution applies to the Outlander PHEV, whose engine compartment and electrical systems differ from gasoline-only versions.
When Should We Visit a Mechanic?
Professional diagnosis makes sense when:
- The reservoir is full but the warning remains
- The tank loses fluid repeatedly
- Wiring is hidden behind body panels
- The vehicle has collision damage
- The sensor connector is corroded
- The warning appears intermittently
- The washers do not operate
- The reservoir is cracked
- The repair requires bumper removal
- We are not comfortable testing electrical circuits
A technician should confirm the failure before replacing parts. Ask whether the problem is the sensor, seal, reservoir, connector, wiring harness, or cluster input.
Quick Diagnostic Checklist
Use this condensed checklist when the message appears:
- Park on level ground.
- Confirm that the washer reservoir is low.
- Fill it with suitable washer fluid.
- Wait for trapped air to escape.
- Recheck the level.
- Close the cap.
- Start the vehicle.
- Operate the washers briefly.
- Cycle the ignition.
- Check for leaks.
- Consider frozen or contaminated fluid.
- Inspect accessible sensor wiring.
- Test the level switch if the warning remains.
- Replace the failed component rather than bypassing it.
Final Thoughts
The normal Mitsubishi Outlander low washer fluid reset is not a complicated dashboard ritual. In most cases, we simply refill the correct reservoir, place the vehicle on level ground, and restart it. The warning should clear automatically once the sensor detects sufficient fluid.
When it does not, repeatedly pressing buttons will not help. The vehicle is usually still receiving a low-level signal because the float is stuck, the fluid is frozen, the sensor has failed, the connector is corroded, the wiring is damaged, or the reservoir is leaking.
Our best strategy is calm and methodical. Start with the fluid level, check the simple possibilities, and move toward electrical testing only when necessary. That approach is quicker, safer, and far less expensive than replacing parts at random.
A persistent warning may be small, but visibility is never a small issue. Restore the system properly, and the next muddy road or sudden rainstorm will not catch us staring through a dirty windshield.
Frequently Asked Questions
1. How do I reset the Mitsubishi Outlander low washer fluid warning?
Fill the washer reservoir with appropriate windshield washer fluid, park on level ground, close the cap, and restart the vehicle. The warning normally resets automatically. Most models do not require a special button sequence.
2. Why does my Outlander still say low washer fluid when the tank is full?
The most likely causes are a stuck reservoir float, a defective level sensor, frozen or contaminated fluid, a loose connector, damaged wiring, or a reservoir that is slowly leaking.
3. Can I clear the washer fluid warning with an OBD2 scanner?
Usually, a scanner is not needed. The message should disappear when the level-switch signal changes. A professional scan tool may help diagnose body-control or cluster data, but clearing codes will not repair a faulty sensor or wiring problem.
4. Where is the Mitsubishi Outlander washer fluid sensor located?
On models equipped with a level sensor, it is generally mounted in or near the lower portion of the washer reservoir. Access may require removal of an inner fender liner, splash shield, wheel, or bumper component, depending on the model year.
