Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and basic hand tools.
Park the vehicle on a flat surface and ensure it is in "Park" (for automatic) or in gear (for manual).

2. Check and Adjust Tire Pressure

Sub-step 1: Remove the valve stem cap from each tire.
Sub-step 2: Use the tire pressure gauge to check the pressure of each tire.
Sub-step 3: Compare the readings to the manufacturer’s recommended pressure.
Sub-step 4: If the pressure is low, use an air compressor to inflate the tire to the correct pressure.
Sub-step 5: Recheck the pressure to ensure it is correct after inflation.
Sub-step 6: Replace the valve stem cap securely after checking.

3. Reset TPMS (if required)

Sub-step 1: Turn on the ignition without starting the engine.
Sub-step 2: Locate the TPMS reset button (usually under the steering wheel or in the glove box).
Sub-step 3: Press and hold the reset button until the TPMS light blinks three times, then release it.
Sub-step 4: Start the engine and allow the vehicle to run for a few minutes to verify that the warning light has turned off.
