Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and TPMS reset tool if needed.
Ensure the vehicle is parked on a level surface with the engine off.

2. Check and Adjust Tire Pressures

Sub-steps:
1. Remove valve caps from all tires.
2. Use the tire pressure gauge to measure the current pressure in each tire.
3. Compare the readings with the recommended tire pressure found on the driver's door jamb or in the owner's manual.
4. If any tire is underinflated, use the air compressor to inflate it to the recommended level.
5. Replace the valve caps securely after adjusting pressures.

3. Inspect Tires

Sub-steps:
1. Visually inspect each tire for cuts, punctures, or bulges.
2. Check for any embedded objects (nails, screws) that may cause slow leaks.
3. Look for uneven tire wear which may indicate misalignment or suspension issues.

4. Reset the TPMS (if applicable)

Sub-steps:
1. Turn on the vehicle without starting the engine.
2. Access the TPMS reset option through the vehicle settings menu on the touchscreen.
3. Follow the prompts to reset the TPMS.
4. Confirm the reset on the display and ensure the warning light turns off.
