Checking tire inflation pressure
electronically
The tire inflation pressure monitor only
functions on wheels that are equipped with
the proper electronic sensors. It monitors
the tire inflation pressure, as selected by
the driver, in all four tires. A warning is
issued to alert you to a decrease in tire
inflation pressure in one or more of the
tires.
You can call up the tire inflation pressure
monitoring display using the control
system (
୴ page 137).
̈ Switch on the ignition (୴ page 40).
̈ Press button è or ÿ on the
multifunction steering wheel
repeatedly until the standard display
menu appears in the multifunction
display (

̈ Press button k repeatedly until the
current tire inflation pressures for each
tire appear in the multifunction display.

After you have reactivated the tire infla-
tion pressure monitor, the current tire
inflation pressures will only be shown
after a few minutes driving time.
During this time you will see the
following message in the multifunction
display:

Possible differences between the read-
ings of a tire inflation pressure gauge of
an air hose, e.g. gas station equipment,
and the vehicle’s control system can
occur. The readings issued by the
control system are more precise.

You can select the unit of measure
(bar/psi) used for the tire inflation
pressure by changing the setting in the
