Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, TPMS tool, jack, jack stands
Ensure the vehicle is parked on a level surface and the engine is turned off.
Allow tires to cool down for accurate pressure readings.

2. Check Tire Pressure

Remove the valve stem caps from each tire.
Use the tire pressure gauge to measure the pressure in each tire.
Refer to the vehicle's door jamb for the manufacturer's recommended tire pressure.

3. Inflate Tires

If any tire is below the recommended pressure, use an air compressor to inflate to the correct level.
Recheck the pressure after inflating to ensure it meets specifications.

4. Inspect and Replace TPMS Sensors (if necessary)

If tire pressure is correct and the warning persists, check the TPMS sensors.
Remove the tire from the wheel if replacing sensors.
Install new TPMS sensors according to manufacturer specifications.
Reinstall the tire and ensure it is properly seated on the rim.

5. Reset TPMS

After repairs, reset the TPMS through the vehicle's settings menu.
Drive the vehicle for a short distance to allow the system to recalibrate.
