Solution

1. Preparation

Gather necessary tools including a tire pressure gauge and a portable air compressor if needed.
Ensure vehicle is parked on a level surface with the engine off.

2. Check and Adjust Tire Pressures

Sub-steps:
1. Remove valve caps from each tire.
2. Use the tire pressure gauge to check the pressure of each tire.
3. Inflate tires to the recommended pressure (usually found on the driver's side door jamb).
4. Reinstall valve caps securely after checking.

3. Reset the Tire Pressure Monitoring System (TPMS)

Sub-steps:
1. Turn on the ignition without starting the engine (position II).
2. Locate the TPMS reset button, usually found under the steering wheel or in the glove box.
3. Press and hold the TPMS reset button until the tire pressure light blinks three times, then release.
4. Start the engine and allow the vehicle to run for a few minutes for the system to recalibrate.
