Important safety notes If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you when
the pressure drops in one or more of the
tyres. The tyre pressure monitor only func-
tions if the correct sensors are fitted to all
wheels.
G
WARNING
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. The table
on the inside of the fuel fillerf lap will help you
decide whether the tyre pressures should be
corrected.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object. In the
even tofa sudden loss of pressure, bring the
vehicle to a halt by braking carefully.D o not
make any sudden steering movements when
doing so.
Information on tyre pressures is displayed in
the multifunction display .After a few minutes
of driving, the current tyre pressure of each
tyre is show ninthe multifunction display.
i The tyre pressure values indicated by the
on-board computer may differ from those
measured at a filling station with a pressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tyre pres-
sure values indicated by a pressure gauge
are higher than those shown by the on- board computer. In this case, do not reduce
the tyre pressures.
i The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
Checking tyre pressure electronically X
Make sure that the key is in position 2
(Y page 137) in the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Service menu.
X Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The current tyre pressure for each wheel
will be displayed in the multifunction dis-
play.
If the vehicle has been parked for longer than
20 minutes, the Tyre pressures will be
displayed after a few minutes of
driving message appears.
After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the Tyre pressure monitor active display mes-
sage is shown instead of the tyre pressure
display. The tyre pressures are already being
monitored.
i If a spare wheel/emergency spare wheel
is fitted, the system may continue to show
the tyre 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 wheel/emer-
gency spare wheel is fitted is not the same
as the spare wheel/emergency spare
wheel's current tyre pressure. 342

Tyre pressure monitor warning mes-
sages If the tyre pressure monitor detects a signifi-
cant pressure loss on one or more tyres, a
warning message is shown in the multifunc-
tio nd isplay. Awarning tone also sounds and
the tyre pressure warning lamp lights up in
the instrument cluster.
Each tyre that is affected by a significant loss
of pressure is highlighted in the pressure dis-
play.
If the Please correct tyre pressure message appears in the multifunction dis-
play:
X Chec kthe tyre pressure on all four wheels
and correct it if necessary.
i If the wheel positions on the vehicle are
interchanged, the tyre pressures may be
displayed for the wrong positions for a
short time. This is rectified after a few
minutes of driving, and the tyre pressures
are displayed for the correct positions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
ence values for monitoring. In most cases, the
tyre pressure monitor will automatically
detect the new referencev alues after you
have changed the tyre pressure.
i For an overview of th emenus, see
(Y page 214).
If you wish to define the new reference values
manually:
X Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions. Also observe the notes in the section on
tyre pressures (Y
page 339).
X Make sure that the key is in position 2in
the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Service menu.
X Press the 9or: button to select

the multifunction display.
If you wish to confirm the restart:
X Press the abutton.
The Tyre press. monitor restarted message appears in the multifunction dis-
play.
After you have driven for a few minutes, the
system checks whether the current tyre
pressures are within the specified range.
The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
X Press the %button.
The tyre pressure values stored at the last
restart will continue to be monitored.
