Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, torque wrench, and possibly a diagnostic tool.
Park the vehicle on a level surface and ensure the tires are cold for accurate pressure readings.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve cap from each tire.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. Inflate each tire to the recommended pressure as indicated on the driver’s side door jamb sticker (typically between 30-35 PSI).
4. Ensure to recheck the pressure after inflating.
5. Replace the valve caps securely.

3. Inspect and Repair Tires

Sub-steps:
1. Visually inspect each tire for punctures, cuts, and sidewall bulges.
2. If any damage is found, consider patching or replacing the tire.
3. If no visible damage is found but a tire is losing pressure, check for leaks using soapy water.

4. Reset TPMS (if necessary)

Sub-steps:
1. If the tire pressure has been adjusted, reset the TPMS through the vehicle settings menu.
2. Navigate to the “Service” or “Tire” section in the touchscreen and select “Reset Tire Pressure.”
3. Confirm the reset and allow the system to recalibrate.
