nificantly too low. The tire pressure monitor is
not malfunctioning.
RUSA only: if thehwarning lamp flashes for
60 seconds and then remains lit constantly,
the tire pressure monitor is malfunctioning.
The display also shows a message:

USA only: if the tire pressure monitor is mal-
functioning, it may be more than ten minutes
before the malfunction is shown. The htire
pressure warning lamp flashes for 60 seconds
and then remains lit. When the malfunction has
been rectified, the htire pressure warning
lamp goes out after a few minutes of driving.
The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gauge.
The tire pressures shown by the on-board com-
puter refer to those measured at sea level. At
high altitudes, the tire pressure values indicated
by a pressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tire pressures.
If radio transmitting equipment (e.g. wireless
headphones, two-way radios) is operated inside
the vehicle or in the vicinity of the vehicle, this
can interfere wi th th
e operation of the tire pres-
sure monitor.
Checking the tire pressure electroni-
cally on vehicles with steering wheel
buttons
You can only check the tire pressure electroni-
cally on vehicles with steering wheel buttons.
Using the steering wheel buttons
XTurn the key to position 2in the ignition
lock.
XPress the =or; button to select the
Servicemenu.
XUse the 9or: button to select TirePressure.
XPressato confirm.
The current tire pressure of each wheel is
shown in the display.
If the vehicle has been parked for over
20 minutes, the Tire pressure will be
displayed after driving a few minutesmessage appears.
After a teach-in period, the tire pressure monitor
automatically detects new wheels or new sen-
sors. As long as a clear allocation of the tire
pressure value to the individual wheels is not
possible, theTire
PressureMonitorActivemessage is shown instead of the tire pressure
display. The tire pressures are already being
monitored.
Tire pressure monitor warning mes-
sages
If the tire pressure monitor detects a loss in
pressure in one or more tires, a warning mes-
sage is shown in the display. The hwarning
lamp lights up.

RIf the Correct Tire Pressuremessage is
shown in the display, the tire pressure in at
least one tire is too low. The tire pressure
must be corrected at the next opportunity.
RIf the CheckTirePressureSoonmessage
is shown in the display, the tire pressure in
one or more tires has dropped significantly.
The tires must be checked.
RIf the Warning Tire Malfunc.message is
shown in the display, the tire pressure in one
or more tires has dropped suddenly. The tires
must be checked.
Vehicles with steering wheel buttons
RIf the Adjust Tire Pressuremessage is
shown in the display, the tire pressure in at
least one tire is too low. The tire pressure
must be corrected at the next opportunity.
RIf the Check Tiresmessage is shown in the
display, the tire pressure in one or more tires has dropped significantly. The tires must be
checked.
RIf the WarningTireMalfunctionmessage
is shown in the display, the tire pressure in
one or more tires has dropped suddenly. The
tires must be checked.
Always read and follow the instructions and
safety notes related to the display messages,
which can be found in the "Tires" section.
