Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, valve stem tool, and possibly a jack and jack stands if tire removal is needed.
Ensure the vehicle is parked on a level surface and the tires are cold (preferably after the vehicle has been stationary for several hours).

2. Adjust Tire Pressure

Sub-step 1: Use the tire pressure gauge to measure each tire's pressure.
Sub-step 2: If any tire is above the recommended pressure, release air using the valve stem tool until the correct pressure is achieved.
Sub-step 3: Inflate under-inflated tires to the recommended pressure using the air compressor.
Safety Warning: Do not exceed the maximum tire pressure listed on the tire sidewall.

3. Reset TPMS (if applicable)

Sub-step 1: Access the vehicle's settings on the central display.
Sub-step 2: Navigate to the 'Service' menu and select 'Reset Tire Pressure Monitoring System'.
Sub-step 3: Follow on-screen prompts to complete the reset procedure.
