TIRE PRESSURE MONITOR SYSTEM (TPMS)

Note. To determine appropriate TPMS reset procedure, refer to STORING TIRE INFLATION PRESSURES INDEX . Only vehicles listed in this index have a TPMS display or a reset procedure.

Note. In order for the tire pressure monitoring system to work, the specified pressures (provided on tire pressure label) must be reprogrammed after every change in air pressure.

Note. Whenever tire pressure is adjusted (i.e., when readjusting tire pressure for a load condition), or after every wheel change, the adjusted pressure has to be stored again. See appropriate STORING TIRE INFLATION PRESSURES procedure.

STORING TIRE INFLATION PRESSURES INDEX

STORING TIRE INFLATION PRESSURES - PROCEDURE 1

1. Ensure air pressure in all tires (including spare tire) is properly adjusted to specification.
2. On the center instrument cluster display, press the MENU button. (Scheme 6)
3. Push the turn-switch to select "SET" option. (Scheme 7)
4. Turn the switch to scroll to "TYRE PRESSURE", then push switch. (Scheme 8)
5. Push the switch again to select "STORE PRESSURES". (Scheme 9) After the tire pressures have been saved, the system will measure the actual pressures once again, and then save these as the new pressures.

Scheme 8

Scheme 9

STORING TIRE INFLATION PRESSURES - PROCEDURE 2

1. Ensure air pressure in all tires is properly adjusted to specification.
2. On the center instrument cluster display (on some models, in MMI), press the CAR function button. (Scheme 10) NOTE: On some newer models start menu selection with SERVICING & CHECKS.
3. Select TIRE PRESSURE MONITORING.
4. Select STORE TIRE PRESSURES or STORE NOW.

or

Scheme 10

STORING TIRE INFLATION PRESSURES - PROCEDURE 3

Note. In order for the tire pressure monitoring system to work, the specified pressures (provided on tire pressure label located on driver's side door pillar) must be reprogrammed after every change in air pressure or after every wheel change.

1. Turn ignition switch to ON position.
2. Press the MENU button to open the start menu.
3. Move the selection arrow to "SET" by rotating the turn/push knob.
4. Press the turn/push knob. The settings menu will appear.
5. Move the selection arrow to "TIRE PRESSURE" by rotating the turn/push knob.
6. Press the turn/push knob. The sub-menu TIRE PRESSURE will appear.
7. Move the selection arrow to "STORE PRESSURES!". (Scheme 11) When this is initiated, the system automatically starts the learning procedure. NOTE: The learning procedure is launched by storing the air pressures. It takes several minutes while you are driving. The system will learn the tire pressures set on the vehicle, and will check to see if any tires were changed. During the learning phase, the system is operable, but will only issue a warning when the pressure in one or more tires (including the spare) deviates from the specified pressure by more than 6 psi (41 kPa). If this occurs, the Red tire warning symbol and "CHECK TIRE PRESSURE" message will appear. NOTE: If a tire symbol with a slash through it appears in the display at the end of a learning phase, it means that the system cannot recognize which wheels are mounted on the vehicle. This may be because one or more wheels were mounted lacking a wheel sensor. NOTE: During the learning phase, if the system determines that there is a difference of more than 6 psi (41 kPa) between the air pressures on one axle, a message will be displayed showing both affected wheels.
8. Press the turn/push knob. A check mark will appear. The system reports that the store request was saved with "THE CURRENT TIRE PRESSURES WILL BE SAVED".
9. Move the selection arrow to "BACK".
10. Press the turn/push knob to leave the tire pressure menu.

Scheme 11

STORING TIRE INFLATION PRESSURES - PROCEDURE 5

Note. In order for the tire pressure monitoring system to work, the specified pressures (provided on tire pressure label located on driver's side door pillar) must be reprogrammed after every change in air pressure or after every wheel change.

STORING TIRE INFLATION PRESSURES - PROCEDURE 8

Note. The correct saving of the specified values is a basic requirement for accurate tire pressure monitoring.

Basic Procedure

1. Adjust air pressure in all tires to specifications (provided on tire pressure label located inside fuel filler door/B pillar).
2. Turn ignition ON.
3. Vehicle must be stationary.
4. Press the Tire Pressure Monitoring button on the center console switch strip for approximately 5 seconds or until a signal tone is heard and the Yellow malfunction light in the instrument cluster flashes several times, this confirms the calibration procedure.

Replacing A Tire Or Tire Pressure Sensor

Each time a tire is changed or a tire pressure sensor is replaced, the tire pressure monitoring button in the center console must be pressed for approximately 5 seconds with the ignition switched on and vehicle still under a signal tone is heard and the yellow system malfunction diagram in the instrument cluster blinks several times.

If the tire pressure monitoring button is not pressed, the system learns the new sensors but still activates the malfunction lamp to request active operation.

The vehicle must now stand for 20 minutes and then be driven on a 10 minute adaptation drive at speeds greater than 25 km/h. If the standing time is not followed, control module is not in learning mode so system recognizes a malfunction and can only automatically learn wheel electronics after standing 20 minutes.
