Solution

1. Preparation

Ensure the vehicle is parked on a level surface and is turned off.
Gather necessary tools: a tire pressure gauge and the vehicle's owner's manual for reference.

2. Correct Tire Pressures

Use the tire pressure gauge to measure the current pressure of each tire.
Inflate any tires that are below the recommended pressure to the specified PSI as indicated on the driver's side door jamb sticker.

3. Reset Tire Pressure Monitoring System (TPMS)

Turn on the ignition without starting the engine (press the start button without pressing the brake pedal).
Access the vehicle's iDrive system:
- Navigate to "Vehicle Info" using the iDrive controller.
- Select "Vehicle Status."
- Choose "Tire Pressure Monitor."
Select "Reset" or "Initialize" to reset the TPMS.
Confirm the reset when prompted.

4. Verify Reset

Turn off the ignition and then start the vehicle to ensure the tire pressure light is no longer illuminated.
