⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure that tires are cool to the touch when checking pressure, as heat can increase pressure readings.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Incorrect tire pressure readings displayed
•Possible decrease in fuel efficiency
•Vehicle handling issues due to under-inflated tires

Diagnostic Steps

1
Check the tire pressures on all four tires using a tire pressure gauge.
2
Inflate or deflate tires to the recommended pressure specified on the driver’s side door jamb.
3
Inspect the spare tire, as some systems include monitoring for the spare tire as well.
4
Ensure the tire valve stems are not damaged or leaking.
5
If tire pressures are correct and the light remains on, proceed to reset the tire pressure monitoring system (TPMS).

Solution

1. Preparation

Gather necessary tools:
- Tire pressure gauge
- Air compressor (if needed for inflation)

2. Inflate Tires

Sub-steps:
- Remove valve caps from each tire.
- Use the tire pressure gauge to check the pressure of each tire.
- If any tire is below the recommended pressure, inflate it using the air compressor until it reaches the specified PSI.
- Replace all valve caps securely after adjusting the pressures.

3. Reset the Tire Pressure Monitoring System (TPMS)

Sub-steps:
1. Sit in the driver’s seat and close all doors.
2. Turn the ignition to the "ON" position without starting the engine.
3. Locate the TPMS reset button beneath the steering column (refer to the owner’s manual if necessary).
4. Press and hold the TPMS reset button until the tire pressure warning light blinks three times, then release it.
5. Start the engine and allow the vehicle to run for a few minutes, which should complete the reset process.

4. Final Check

Sub-steps:
- After resetting, monitor the tire pressure light to ensure it remains off during driving.
- Check tire pressures again after driving a short distance to ensure they are stable.
