Mazda CX-5 Maintenance Reset Guide (2012–2020): Step-by-Step Wrench Light Reset

Keeping your Mazda CX-5 in top condition means knowing how to reset the service maintenance reminder—also known as the wrench light—after performing an oil change, tire rotation, or scheduled service. This comprehensive guide walks through every method for both Type A and Type B audio systems, covering CX-5 models from 2012 to 2020, including Sport, Touring, Grand Touring, Grand Touring Reserve, Signature, and Diesel variants.

Understanding the Mazda CX-5 Wrench Light

The wrench symbol on the Mazda CX-5 dashboard indicates that routine maintenance is due—commonly for an engine oil change, tire rotation, or general service. Once maintenance is complete, the reminder must be manually reset using the vehicle’s trip button or infotainment system, depending on your model.

Resetting the Wrench Light: Type A Audio System (2012–2016)

For early Mazda CX-5 models equipped with the Type A audio system (non-touchscreen), the process is simple and requires only the trip button.

Steps:

1. Turn Ignition ON (Engine Off):
   Press the start button twice without pressing the brake, or turn the key to “ON” without starting the engine.
2. Press and Hold the TRIP Button:
   With the ignition switched OFF, press and hold the TRIP button located on the instrument cluster.
3. Switch Ignition ON While Holding:
   Keep holding the TRIP button, then switch the ignition ON.
4. Wait for the Warning Light to Flash:
   Continue holding the button for at least 5 seconds until the master warning light flashes.
   This indicates the reset is complete.

Notes:

• The engine oil flexible maintenance system (available on select models) calculates oil life based on driving conditions.
• Even if the wrench light doesn’t illuminate, the system must still be reset after an oil change.

Resetting the Wrench Light: Type B Audio System (2017–2020)

Newer Mazda CX-5 models feature a Type B audio system with a central infotainment display, where resets are handled via the touchscreen interface.

Steps:

1. Turn Ignition ON:
   Press the START/STOP button twice (without pressing the brake) to power the electronics.
2. Open the Application Menu:
   From the home screen, select “Applications.”
3. Select Maintenance Menu:
   Tap on “Maintenance.”
4. Adjust Maintenance Settings:
   • Notifications: Toggle maintenance reminders on or off.
   • Time (Months): Set or view time remaining until next service.
   • Distance (Miles/Km): Set or view remaining mileage before next maintenance is due.
5. Select “Reset” Option:
   Highlight the maintenance type (Oil Change, Tire Rotation, or General Maintenance) and press “Reset.”
6. Confirm Reset:
   Choose “Yes” to confirm. The system resets both time and distance counters to default.

Oil Change Reminder Reset (All Models)

After every oil change, reset the oil life system to restore accurate monitoring.

Steps:

1. Ignition ON, Engine Off.
2. Go to Applications → Maintenance → Oil Change.
3. Select Reset and confirm with “Yes.”
4. The oil life will reset to 100%, and the wrench light will disappear.

Oil Life Indicator Details:

• The warning light illuminates when remaining oil life is below:
  • 1,000 km (600 miles)
  • 15 days remaining

Tire Rotation Reminder Reset (All Models)

If you rotate your tires, update the reminder system to track the next rotation interval.

Steps:

1. Ignition ON (without engine start).
2. Go to Applications → Maintenance → Tire Rotation.
3. Adjust the distance setting or choose Reset.
4. Confirm with “Yes.”

This resets the counter to the initial tire rotation interval.

Flexible Oil Maintenance System Explained

Some CX-5 models are equipped with Flexible Oil Maintenance, which intelligently monitors oil condition and driving patterns.

• The onboard computer calculates oil degradation using engine load, speed, and operating temperature.
• The service interval can vary depending on driving conditions:
  • Short trips / stop-start traffic: More frequent oil changes.
  • Highway driving: Extended oil change intervals.

Even when no warning appears, always reset the system after replacing engine oil to recalibrate internal calculations.

Common Reasons the Wrench Light Stays On

If the wrench light doesn’t reset properly, verify the following:

Reset Confirmation

After a successful reset:

• The wrench icon disappears from the dashboard.
• The master warning light no longer flashes.
• Maintenance intervals in the infotainment system return to default values.
