Solution

1. Tire Pressure Adjustment

Sub-step 1: Use a tire pressure gauge to measure the pressure in each tire.
Sub-step 2: Inflate any under-inflated tires to the recommended pressure as specified in the owner’s manual (usually found on the driver’s door jamb).
Sub-step 3: If any tire is over-inflated, release some air until the correct pressure is achieved.

2. Tire Inspection and Repair

Sub-step 1: For any visible damage, remove the wheel from the vehicle.
Sub-step 2: Inspect the tire's interior and exterior for punctures or irregular wear.
Sub-step 3: If a puncture is found, use a tire plug kit to repair small punctures or take the tire to a professional for patching.
Sub-step 4: If the tire is severely damaged, replace it with a new tire suitable for the vehicle.

3. TPMS Reset (if applicable)

Sub-step 1: After adjusting tire pressure, check if the TPMS warning light is still on.
Sub-step 2: If the light remains illuminated, navigate to the vehicle settings on the touchscreen.
Sub-step 3: Select 'Service' and then 'Tire Pressure Monitoring System' to reset the TPMS.
