Operation Tires and wheels Reactivating Advanced TPMS The Advanced TPMS must be reactivated when you have adjusted the tire inflation pressure to a new level (e.g. because of different load or driving conditions). The Advanced TPMS is then recalibrated to the current tire inflation pressures. Warning! i Reactivate the Advanced TPMS after adjusting the tire inflation pressure to the inflation pressure recommended for the vehicle operating condition. Tire inflation pressure should only be adjusted on cold tires. Observe the recommended tire inflation pressure on the Tire and Loading Information placard on the driver's door B-pillar ( page 564). Some vehicles may have supplemental tire inflation pressure information for driving at high speeds ( page 570) or for vehicle loads less than the maximum loaded vehicle condition. If such information is provided, it can be found on the inside of the fuel filler flap ( page 550). Press #.

Using the Tire and Loading Information placard on the driver's door B-pillar ( page 564) or, if available, the supplemental tire inflation pressure information on the inside of the fuel filler flap ( page 550), make sure the tire inflation pressure of all four tires is correct. i The menu overview can be found on ( page 284).
