Diagnostic Steps

1
Check the tire pressure in all four tires using a tire pressure gauge.
2
Inspect each tire visually for any obvious damage, punctures, or irregularities.
3
Verify that the tire pressure monitoring system (TPMS) sensors are functioning properly.
4
Check for any recent tire changes or rotations that may have triggered the warning.
5

Solution

1. Preparation

Gather necessary tools such as a tire pressure gauge and a portable air compressor.
Ensure the vehicle is parked on a level surface and the tires are cold for an accurate reading.

2. Check and Adjust Tire Pressure

Remove the valve stem caps from all tires.
Use the tire pressure gauge to measure the pressure in each tire.
Refer to the manufacturer's recommendations (typically found on a sticker inside the driver's door jamb) for the correct tire pressure.
If any tire is below the recommended pressure, use the portable air compressor to inflate it to the correct level.
After adjusting, replace the valve stem caps securely.

3. Reset the TPMS

Turn on the vehicle and navigate to the settings menu on the infotainment screen.
Locate the tire pressure monitoring settings and select the option to reset or recalibrate the TPMS.
Follow any prompts on the screen to complete the reset.

4. Inspect TPMS Sensors (if necessary)

If the warning persists after adjusting tire pressure, the TPMS sensors may need inspection.
Remove the tire (if required) to access the sensor.
Inspect the sensor for damage or corrosion and replace it if necessary.
