Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the tires are cold for accurate pressure readings.

2. Inflate Tires

Sub-steps:
1. Remove the valve cap from the tire with low pressure.
2. Use an air compressor to inflate the tire to the manufacturer's recommended pressure (usually found on the driver's door jamb).
3. Recheck the pressure using the tire gauge after inflating.
4. Replace the valve cap securely.

3. Inspect and Repair (if necessary)

Sub-steps:
1. If any tire is damaged or punctured, remove the tire using a jack and lug wrench.
2. Inspect the tire for punctures or sidewall damage.
3. If a puncture is found, either plug it with a tire repair kit or take it to a professional for repair.
4. If the tire is too damaged, replace it with a new tire.

4. Reset the TPMS

Sub-steps:
1. After correcting tire pressures, turn the vehicle on.
2. Navigate to the settings menu on the display.
3. Select 'Service' and then 'TPMS Reset' to recalibrate the system.

Tools Required:

Digital tire pressure gauge
Air compressor
Jack and lug wrench (if tire removal is necessary)
Tire repair kit (if necessary)

Parts Required:

Tire valve cap (if lost)
Tire repair kit (if punctured)
Replacement tire (if damaged beyond repair)

Estimated Repair Time: 30 minutes to 1 hour

Safety Warnings:

Always wear safety glasses when working with tires.
Ensure the vehicle is on a stable surface before lifting.
Allow tires to cool before checking pressure to avoid inaccurate readings.
