Tire Pressure Monitor System REINITIALIZATION

CAUTION: When driving with snow chains or a space-saver spare tire, DO NOT initialize the system.

NOTE: If you are prompted to check the tire pressure shortly after a reset has been made, this indicates that the corrected values were not accurate. Please check the inflation pressure again, and reactivate the system.

1. Set the tire pressure of all wheels to specification.
2. Start the engine, but do not begin to drive.
   NOTE: On X5 vehicles with a TPMS button marked RDC (see Fig 1), you might need to turn the ignition to the ON position, BUT DO NOT START THE ENGINE, before performing the next step.
3. Press TPMS reset button until the TPMS indicator lamp in the instrument cluster comes on for several seconds or the message "SET TIRE PRESSURE" appears in the Check Control. See Fig 1 or Fig 2.
4. Drive vehicle. Initialization is automatically completed during the drive, without any additional feedback.
