Checking tire pressure electronically*
(vehicles produced up to approximate-
ly October 2003)
i
Check with an authorized
Mercedes-Benz Center to determine
the equipment installed in your vehicle.
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 is-
sued to alert you to a decrease in pressure
in one or more of the tires.
Tire pressure inquiries are made using the
multifunction display ( page 134). The in-
flation pressures are displayed only after a
few minutes travel time.
You can select the unit of measure used for
the tire inflation pressure by changing the
setting in the control system ( page 134).
i
Possible differences between the read-
ings of a tire 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 sys-
tem are more precise.
Switch on ignition.
Press button è or ÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
( page 134).
Press button k or j repeatedly
until you see the current inflation pres-
sures for each tire appear in the dis-
play.

Warning!
The tire inflation pressure monitor does not
indicate a warning for wrongly selected in-
flation pressures. Always adjust tire inflation
pressure according to the label on the fuel
filler flap.
The tire inflation pressure monitor is not
able to issue a warning due to a sudden dra-
matic loss of pressure (e.g. tire blowout
caused by a foreign object). In this case
bring the vehicle to a halt by carefully apply-
ing the brakes and avoiding abrupt steering
maneuvers.
i
Operating radio transmission equip-
ment (e.g. wireless headsets, two-way
radios) in or near the vehicle could
cause the tire inflation pressure moni-
tor to malfunction.
