Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, valve stem tool (if needed).
Ensure the vehicle is parked on a level surface and the tires are cold (not driven recently).

2. Inflate Tires

Sub-steps:
1. Remove the valve cap from the tire that is low on pressure.
2. Attach the air compressor nozzle to the valve stem.
3. Inflate the tire to the recommended PSI as per the tire placard.
4. Recheck the pressure with the tire pressure gauge after inflating.
5. Replace the valve cap securely.

3. Reset TPMS Light

Sub-steps:
1. Start the engine and let it run for a few minutes.
2. Locate the TPMS reset button (usually found beneath the steering wheel or in the glove box).
3. Press and hold the reset button until the TPMS light blinks three times, indicating that the system is resetting.
4. Turn off the engine and restart to verify the light remains off.
