Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and basic hand tools if needed.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Check and Inflate Tires

Sub-step 1: Remove the valve caps from each tire.
Sub-step 2: Use the tire pressure gauge to check the current pressure of each tire.
Sub-step 3: Compare the readings with the manufacturer's recommended tire pressure, typically found on a sticker inside the driver’s door jamb.
Sub-step 4: If the tire pressure is low, use an air compressor to inflate the tire to the recommended pressure.

3. Inspect and Repair Tires

Sub-step 1: If any tire shows signs of damage or is unable to hold air, remove the tire from the vehicle using appropriate tools.
Sub-step 2: Inspect the tire for punctures or tears and determine if it can be repaired or needs to be replaced.
Sub-step 3: If repairable, use a tire plug kit as per the manufacturer's instructions or take it to a professional for rubber patching.

4. Reset TPMS

Sub-step 1: After inflating or repairing, turn on the vehicle and navigate to the TPMS settings in the main display.
Sub-step 2: Follow the on-screen instructions to reset the TPMS system.
Sub-step 3: Confirm that the warning message has cleared from the dashboard.
