Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is in the "OFF" position.
Gather necessary tools: a tire pressure gauge and the vehicle key fob.

2. Adjust Tire Pressures

Sub-step 1: Check the recommended tire pressure, which can usually be found on the driver’s side door jamb or in the owner's manual.
Sub-step 2: Inflate or deflate each tire to match the recommended pressure, using an air compressor or tire inflator.
Sub-step 3: Confirm that all tires are set to the correct pressure using the tire pressure gauge.

3. Reset TPMS

Sub-step 1: Turn the ignition to the "ON" position without starting the engine.
Sub-step 2: Press the "Menu" button on the iDrive controller.
Sub-step 3: Navigate to "Vehicle Status" and select "Tire Pressure Monitor."
Sub-step 4: Choose the option to "Reset" or "Initialize" the tire pressure monitoring system.
Sub-step 5: Confirm the reset action by following any on-screen prompts.

4. Verify Reset

Sub-step 1: Start the engine and observe if the tire pressure warning light turns off after a few moments.
Sub-step 2: Drive the vehicle for a short distance (approximately 10-15 minutes) to allow the TPMS to recalibrate.
