Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and possibly tire sealant if a puncture is found.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check and Inflate Tires

Sub-step 1: Use the tire pressure gauge to check the pressure of all four tires.
Sub-step 2: If any tire is below the recommended pressure, inflate it to the specified level using the air compressor.
Sub-step 3: If a tire is significantly low and the cause is unknown, inspect it for punctures or leaks.

3. Repair or Replace

Sub-step 1: If a puncture or damage is found, either repair it using a tire repair kit or take it to a professional for patching.
Sub-step 2: If tire damage is irreparable, replace the tire with a new one that meets manufacturer specifications.

4. Reset TPMS

Sub-step 1: After correcting the tire pressure, navigate to the vehicle's touchscreen.
Sub-step 2: Go to "Service" in the menu and select "Reset Tire Pressure Monitoring System."
Sub-step 3: Confirm the reset to clear any stored warnings.
