Mercedes-Benz GL-Class: Checking tire pressure electronically

► Make sure that the SmartKey is in position 2 in the ignition lock.

► Press and hold the button on the multifunction steering wheel until the standard display appears in the multifunction display.

► Press and hold the button until the current tire pressure of each tire is shown in the multifunction display.

If the vehicle has been parked for longer than 20 minutes, the Tire pressure displayed after driving for several minutes message appears in the display.

After a teach-in period, the tire pressure monitor automatically recognizes new wheels or new sensors. If a clear allocation of the tire pressure values to the individual wheels is not possible, the Tire Pressure Monitor Active message is shown instead of the tire pressure display. The tire pressures are already being monitored.

If a spare wheel/emergency spare wheel is mounted, the system may continue to show the tire pressure of the wheel that has been removed for a few minutes. If this occurs, note that the value displayed for the position where the spare tire is mounted is not the same as the spare wheel/emergency spare wheel's current tire pressure.
