Solution

1. Preparation

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

2. Check Tire Pressure

Sub-step: Remove the valve cap from each tire.
Sub-step: Use a tire pressure gauge to measure the pressure.
Sub-step: Compare the readings with the recommended PSI found on the driver’s side door jamb.
Sub-step: Inflate or deflate tires as necessary to match recommended levels.

3. Reset TPMS

Sub-step: Power on the vehicle and access the touchscreen.
Sub-step: Navigate to “Service” > “Tire Pressure Monitoring System.”
Sub-step: Select the option to reset or recalibrate the TPMS.
Sub-step: Follow any on-screen prompts to complete the reset process.

4. Inspect and Replace Sensors (if needed)

Sub-step: If the light stays on after checking tire pressures and resetting, inspect tire pressure sensors.
Sub-step: Remove the tire from the wheel to access the TPMS sensor.
Sub-step: Replace any faulty TPMS sensors with new ones.
Sub-step: Reinstall the tire and ensure it's properly seated.

5. Final Checks

Sub-step: Recheck tire pressures again after any adjustments.
Sub-step: Drive the vehicle for a short distance to allow the system to recalibrate.
