Tire Pressure Monitor System Activation

CAUTION: The warning system can only operate in a reliable manner if correct tire pressures are set. If an incorrect tire inflation pressure is set, the system will monitor the pressure according to the incorrect value.

When you restart the tire pressure monitor, all existing warning messages are deleted and the warning lamps go out. The monitor uses the currently set tire pressures as the reference values for monitoring. In most cases, the tire pressure monitor will automatically detect the new reference values after you have changed the tire pressure. However, you can also define reference values manually as described here.

NOTE: Set the tire pressure to the value recommended for the corresponding driving situation on the Tire and Loading Information placard on the driver's side B-pillar. Additional tire pressure values for different loads can also be found on the tire pressure table on the inside of the fuel filler flap.

NOTE: TPMS activation is accomplished by using the multifunction display control buttons on left side of steering wheel.
