Hyundai i20 Tyre Pressure Reset: The Complete Step-by-Step Guide for Every Model Year

Maintaining the correct tyre pressure on a Hyundai i20 is more than a routine chore—it’s a direct investment in safety, stability, fuel efficiency, and long-term tyre health. When the TPMS (Tyre Pressure Monitoring System) warning light appears, it signals a pressure imbalance that needs attention. Yet even after restoring the tyres to their proper PSI, many drivers still find the light stubbornly lingering. That’s where a proper Hyundai i20 tyre-pressure reset becomes essential.

We’ve created the most detailed, expert-level guide available—covering every generation, every trim, and every dashboard layout—to ensure your TPMS resets cleanly and confidently. From recommended PSI charts to troubleshooting sensor faults, we leave no detail behind.

Understanding the Hyundai i20 TPMS System

The Hyundai i20 features a direct TPMS, meaning each wheel houses a sensor that continually measures tyre pressure. When one or more tyres fall outside the acceptable PSI range, the dashboard illuminates the familiar amber horseshoe symbol.

A reset becomes necessary when:

• You’ve inflated the tyres to the correct pressure but the TPMS light stays on.
• You’ve rotated the tyres.
• You’ve replaced a tyre, valve, or TPMS sensor.
• Seasonal temperature changes create PSI fluctuations.

Direct TPMS systems are extremely accurate, but they sometimes require manual reinitialisation to clear stored values.

Recommended Tyre Pressure for Hyundai i20 (All Generations)

Below is a consolidated PSI reference for the most common Hyundai i20 engines and trims worldwide.

1st Generation i20 (2008–2014)

2nd Generation i20 (2014–2020)

3rd Generation i20 (2020–Present)

Always verify your exact tyre code against the driver's door-jamb label or manual.

How to Reset Hyundai i20 Tyre Pressure: Complete Procedure

The reset procedure varies slightly depending on your i20’s manufacturing year and whether your car uses a button-based system or an infotainment-menu reset. Below is the universal method that works for all engines and trims.

1. Check and Adjust all Tyre Pressures Precisely

Using a high-quality digital gauge:

• Measure all four tyres (and the spare if fitted with a sensor).
• Inflate or deflate to match the factory PSI chart.
• Ensure all tyres are checked when cold, not after driving.

A single tyre just 2 PSI out of range can prevent the TPMS from resetting.

2. Turn the Ignition to ON (Do Not Start the Engine)

This powers the vehicle’s electronic modules, including the TPMS control unit.

For push-button start:

• Press the button without pressing the brake.
• The dashboard will illuminate, but the engine will remain off.

3. Locate the TPMS Menu on the Cluster or Infotainment Screen

Depending on generation:

• Older models (2008–2014): Look for a physical “SET” or “TPMS RESET” button near the steering column.
• 2014–2020 models: Use steering-wheel arrows → “User Settings” → “Service” → “Tyre Pressure”.
• 2020–Present models: Navigate through the digital cluster → “Vehicle Settings” → “Tyre Pressure” → “Reset TPMS”.

If the reset option is hidden, scroll through all menus—Hyundai often nests the feature under “Driver Assistance.”

4. Select “Reset” or “Initialize”

Press OK/Enter.
The screen may briefly flash or show a confirmation message such as:

• “TPMS Reset in Progress”
• “Relearning Tyre Positions”
• “Drive to Display Updated Values”

5. Start the Engine and Drive for 5–20 Minutes

The TPMS requires rotational wheel data, so the system will not reset unless the vehicle is driven above 20–25 mph (30–40 km/h).

During this relearning drive:

• Maintain steady speed.
• Avoid heavy acceleration or braking.
• Stay on smooth roads if possible.

The light should turn off automatically once the system verifies stable pressure readings.

Why the Hyundai i20 TPMS Light Might Not Turn Off

If the warning symbol remains illuminated after completing the reset steps, there are several likely causes:

1. One Tyre Still Has Incorrect Pressure

Even a small mismatch between tyres can trigger the system.

Checklist:

• Recheck PSI using one single gauge for consistency.
• Compare all values against factory recommendations.
• Inspect for slow leaks or embedded nails.

2. Temperature-Related PSI Drops

Cold weather can decrease tyre pressure by 1 PSI per 10°F (6°C).
If the light reappears overnight, the cause is typically temperature variance.

3. Faulty TPMS Sensor Battery

Most Hyundai TPMS sensors last 5–10 years.
When battery voltage drops, the cluster may show:

• Intermittent warning light
• No pressure displayed for a wheel
• “TPMS Sensor Error” message

Replacement is required.

4. Tyre Rotation Confused the System

If tyres were rotated without recalibrating the TPMS, the system may associate the wrong sensor with the wrong corner.

A reset will realign sensor positions.

5. Aftermarket Wheels or Metal Valves

If non-Hyundai valves are fitted, sensor communication can fail.

• Damaged valve stems
• Incorrect frequency sensors (433 MHz vs 315 MHz)
• Loose TPMS modules after tyre mounting

Only compatible sensors should be used.

How to Perform a Hard Reset (Advanced Method)

If the standard reset doesn’t work, try the full hard-reset process used by technicians:

1. Inflate tyres 3 PSI above recommended pressure.
2. Drive for 10 minutes.
3. Lower pressure to factory PSI.
4. Reset TPMS via the menu again.
5. Drive a further 10 minutes at a stable speed.

This forces the control module to discard stored values and rebuild sensor data.

Professional Calibration Options

If all DIY methods fail, a Hyundai technician can use diagnostic tools such as:

• GDS (Global Diagnostic System)
• OBD-linked TPMS tools (Bartec, Autel)

These devices can:

• Relearn sensor IDs
• Update the TPMS module
• Diagnose weak/broken sensors
• Re-register sensors after wheel replacement

A full scan typically takes 10–15 minutes.

Safety Risks of Ignoring Incorrect Tyre Pressure

Driving with unbalanced or under-inflated tyres can lead to:

• Higher fuel consumption
• Uneven tread wear
• Reduced braking efficiency
• Poor cornering stability
• Increased risk of tyre blowout

The TPMS light should never be ignored—resetting ensures the system continues to monitor real-time safety data.

Frequently Asked Questions

1. Does the Hyundai i20 automatically reset TPMS after inflating tyres?

Newer models (2020+) often reset automatically, but a manual reset from the settings menu ensures immediate recalibration.

2. How do I know if a TPMS sensor is faulty?

If one tyre shows no pressure reading, or the warning remains after proper inflation and resetting, the sensor battery may be dead.

3. Can I drive with the TPMS light on?

You can, but it is unsafe. The light indicates compromised tyre performance or a sensor failure.

4. Should the spare tyre be checked too?

If your spare includes a TPMS sensor (common in some markets), yes—an under-inflated spare can trigger the light.

5. How long does a full reset take?

Typically, 3–5 minutes of menu navigation plus a short drive of 5–20 minutes to complete sensor relearning.

Final Thoughts

Resetting the Hyundai i20 tyre-pressure system is simple once the correct PSI is restored and the TPMS menu is used properly. A clean reset ensures the car monitors tyre safety in real time, keeping your fuel consumption efficient, your handling stable, and your overall driving experience smooth. By following the steps in this comprehensive guide, any Hyundai i20 owner can confidently clear the TPMS light and maintain peak tyre performance year-round.
