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 523). Some vehicles may have supplemental tire inflation pressure information for driving at high speeds ( page 529) 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 509). Press #. You will see the current inflation pressures for each tire or the message "Tire pressures displayed after driving a few minutes" appear in the multifunction display. Press %. The message "Use current pressure values as new reference values To confirm press "OK"" appears in the multifunction display. G It is the driver's responsibility to calibrate the Advanced TPMS on the recommended cold inflation pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle. i After wheel rotation or sensor replacement, the vehicle must be parked for 20 minutes before attempting to reactivate the Advanced TPMS. Using the Tire and Loading Information placard on the driver's door B-pillar ( page 523) or, if available, the supplemental tire inflation pressure information on the inside of the fuel filler flap ( page 509), make sure the tire inflation pressure of all four tires is correct. i The menu overview can be found on ( page 258). Switch on the ignition ( page 336). Press ( or & to select the menu "Service". Press $ or % to select "Tire pressure". 534
