Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
If necessary, remove the valve caps from each tire.

2. Inflate Tires

Sub-steps:
1. Use the tire pressure gauge to check the current pressure of each tire.
2. Refer to the vehicle's door jamb for the recommended tire pressure specifications.
3. Inflate each tire to the recommended pressure using an air compressor.
4. Replace the valve caps securely after inflation.

3. Inspect and Repair Damaged Tires

Sub-steps:
1. If any tire shows signs of damage, such as bulges or punctures, remove the tire from the wheel.
2. Inspect the tire thoroughly for leaks using soapy water; bubbles will indicate a leak.
3. If a puncture is found, use a tire repair kit to patch or plug the hole, or take the tire to a professional for repair or replacement.
4. Reinstall the tire on the wheel, ensuring it is properly seated.

4. Reset TPMS

Sub-steps:
1. Start the vehicle and locate the TPMS reset button (usually found under the steering wheel or in the glove box).
2. Press and hold the reset button until the TPMS light blinks three times, then release.
3. Drive the vehicle for at least 10 minutes at speeds over 30 mph to allow the system to recalibrate.
