Operation Tires and wheels Reactivating Advanced TPMS* The 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 TPMS is then recalibrated to the current tire inflation pressures. Warning! i Reactivate the TPMS after adjusting the tire inflation pressure to the inflation pressure recommended for the vehicle operating condition. Tire pressure should only be adjusted on cold tires. Observe the recommended tire inflation pressure on the placard on the driver's door B-pillar ( page 357). Some vehicles may have supplemental tire pressure information for driving at high speeds ( page 364) or for vehicle loads less than the maximum loaded vehicle condition ( page 364). If such information is provided, it can be found on the inside of the fuel filler flap. Press button è or ÿ on the multifunction steering wheel repeatedly until the standard display menu appears in the multifunction display ( page 168). Press the j or k button repeatedly until you see the current inflation pressures for each tire appear in the display or the following message appears in the multifunction display: Tire pressure displayed only after driving a few minutes G Press the reset button ( page 158). The following message will appear in the multifunction display: Check current tire pressure? It is the driver's responsibility to calibrate the 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. Press the æ button. The following message will appear in the multifunction display: Tire pressure monitor reactivated Using the tire placard on the driver's door B-pillar ( page 357) or, if available, the supplemental tire pressure information on the inside of the fuel filler flap ( page 342), make sure the tire inflation pressure of all four tires is correct. The TPMS will now monitor the tire inflation pressure values of all four tires. If you wish to cancel activation: Press the ç button. 374
