⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely lifted and supported with jack stands if working underneath.
•Always check tire pressure when tires are cold for accurate readings.

Symptoms

•Tire pressure warning light is illuminated on the dashboard
•Possible decrease in ride comfort or stability
•Increased tire noise during driving
•Reduced fuel efficiency due to under-inflation
•Potential for uneven tire wear

Diagnostic Steps

1
Verify tire pressures using a reliable tire pressure gauge.
2
Check the tire pressure monitoring system (TPMS) status via the vehicle's settings.
3
Inspect each tire for visible damage or punctures.
4
Examine the TPMS sensors for any signs of damage or corrosion.
5
Reset the TPMS using the vehicle's onboard settings if pressures are normal.
6
If the light remains on after resetting, scan the vehicle for any error codes related to the TPMS.

Solution

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, OBD-II scanner (if needed), and a jack.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve stem caps from each tire.
2. Use the tire pressure gauge to measure the current tire pressure.
3. Compare the readings to the recommended tire pressure (found on the driver’s door jamb).
4. If pressure is low, use an air compressor to inflate the tires to the recommended level.
5. Recheck tire pressure after adding air to ensure it meets specifications.
6. Replace the valve stem caps securely.

3. Inspect TPMS Sensors

Sub-steps:
1. If the tire pressure is correct and the light remains on, inspect the TPMS sensors.
2. Remove the tire from the wheel if necessary to access the TPMS sensor.
3. Check for physical damage or corrosion on the sensor and replace if needed.
4. Reinstall the tire and ensure it is properly mounted.

4. Reset TPMS

Sub-steps:
1. Turn on the vehicle and navigate to the settings menu on the touchscreen.
2. Locate the TPMS option and select "Reset".
3. Follow the on-screen instructions to complete the reset process.
