Notes: To ensure proper functioning of the tire inflation pressure monitor, the tire inflation pressure should be checked and corrected according to the label affixed inside the fuel filler flap. For a detailed description, refer to page 356. The message "REACTIVATE - TIRE PRESS. MONITOR" appears if the tire inflation pressure shows an increase of 4.4 psi (0.3 bar) or more. Reactivate the tire inflation pressure monitor. The tire inflation pressure monitor only functions on wheels equipped with the proper electronic sensors. Inquire at your authorized Mercedes-Benz Center about retrofitting other than original Mercedes-Benz wheels with electronic sensors. Transporting a deflated road wheel in the vehicle, e.g. after having a flat, the tire inflation pressure monitor should only be activated once the flat tire and rim are removed from the vehicle. To prevent possible damage to the electronic sensors, have tire changes only performed at an authorized Mercedes-Benz Center. For malfunction and warning messages, see page 309. When checking the tire inflation pressure of the road wheels, also check the spare tire. The tire inflation pressure of the spare wheel, mounted or not mounted, is not monitored by the tire inflation pressure monitor. See page 346 for location of the spare wheel, and page 356 for tire inflation pressure.
