Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner, jack and jack stands, torque wrench.
Ensure the vehicle is parked on a level surface with the engine off.
Wear safety gloves and goggles as needed.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve caps from each tire.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. Refer to the owner's manual or the sticker on the driver’s door jamb for the recommended pressure.
4. Inflate any under-inflated tires to the recommended pressure using an air compressor.
5. Replace the valve caps securely.

3. Inspect Tires

Sub-steps:
1. Visually inspect each tire for cracks, bulges, or punctures.
2. Look for signs of uneven wear, which could indicate alignment issues.
3. If any damage is found, consider replacing the tire or having it repaired by a professional.

4. Reset TPMS

Sub-steps:
1. Turn the ignition to the "on" position without starting the engine.
2. Navigate to the vehicle settings using the iDrive controller.
3. Select "Tire Pressure Monitor" and choose the option to reset the TPMS.
4. Confirm the reset and turn off the ignition.

5. Recheck Tire Pressure

After resetting the TPMS, recheck tire pressures again to ensure they remain at the recommended levels.
