Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and that the tires are cool.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from all tires.
2. Use a tire pressure gauge to measure the pressure in each tire.
3. Inflate or deflate tires as necessary to match the recommended pressure listed on the driver’s door jamb.
4. Replace the valve caps securely.

3. Inspect and Replace TPMS Sensors (if needed)

Tools Required: Tire iron, TPMS tool (if available), replacement TPMS sensors
Sub-steps:
1. Loosen and remove the wheel lug nuts with a tire iron.
2. Remove the wheel from the hub assembly.
3. Locate the TPMS sensor inside the tire (typically attached to the valve stem).
4. If the sensor appears damaged or is not functioning, carefully remove it and install the new TPMS sensor according to manufacturer instructions.
5. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

4. Reset the TPMS

Sub-steps:
1. Access the vehicle settings on the touchscreen.
2. Navigate to the tire pressure monitoring section.
3. Select the option to reset or recalibrate the TPMS.
4. Confirm the reset and exit the settings menu.

5. Test Drive the Vehicle

Sub-steps:
1. Start the vehicle and check the dashboard for the tire pressure light.
2. Drive the vehicle for a short distance (around 5-10 miles) to allow the system to recalibrate.
