Checking tire pressure electronically
– Make sure that the SmartKey is in position
2 in the ignition lock.
– Press the
or
button on the
steering wheel to select the Serv. menu.
– Press the
or
button to select
Tire Pressure.
– Press the
button.
The current tire pressure for each wheel will
be displayed in the multifunction display.
If the vehicle has been parked for longer than 20 minutes, the Tire pressure will be displayed after driving a few 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.
