Restart Run Flat Indicator?
Yes Cancel disappears.
The tyre pressure values stored at the last
restart will continue to be monitored.
Checking the tyre pressure electroni-
cally*
The tyre pressure monitor only functions if
the correct wheel electronics are fitted to all
wheels. These monitor the pressure in all four
tyres, which you have set when restarting the
tyre pressure monitor. The monitor warns you
when the pressure drops in one or more of
the tyres.
G Risk of accident
The tyre pressure monitor does not warn
you of an incorrectly set tyre pressure. The
table on the inside of the fuel filler flap 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 event of a sudden loss of pressure,
bring the vehicle to a halt by braking care-
fully. Do not make any sudden steering
movements when doing so.

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.

If you are carrying a deflated tyre in the
vehicle, you may only reactivate the tyre
pressure monitor if:
the deflated tyre is no longer in the vehi-

Calling up the tyre pressure using the
on-board computer
Make sure that the key is in position 2 in
X
the ignition lock.
Press the j or k button to select the
X
tyre pressure function.
The current tyre pressure for each wheel will
be displayed.
If the vehicle has been parked for longer than
20 minutes or you have not driven faster than
25 km/h since the vehicle was parked, the
following message appears:
Tyre pressure displayed only after
driving for a few minutes
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 tyres pressures shown by the
on-board computer refer to those meas-
ured at sea level. The tyre pressure values
indicated by the on-board computer may
differ when the vehicle is at high altitude.
In this case, do not reduce the tyre pres-
sures.
Tyre pressure warning
If the tyre pressure on one or more wheels
drops significantly, a message appears in the
multi-function display.
The tyre pressure of the affected wheel(s) will
be displayed in a red rectangle. You will also
hear a warning tone.
