Tyres and wheels
229if 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.
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.
i If you are carrying a deflated tyre in the
vehicle, you may only reactivate the tyre
pressure monitor if:
R the deflated tyre is no longer in the vehi-
cle
R you have adjusted the tyre pressure cor-
rectly
Calling up the tyre pressure using the
on-board computer X
Make sure that the key is in posi-
tion 2(Y page 76) in the ignition lock.
X Press the jork button to select the
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 a pressure gauge when the
vehicle is at high altitude are higher than
those shown by the on-board computer. In
this case, do not reduce the tyre pressures. 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.
Restarting the tyre pressure monitor In most cases, the tyre pressure monitor will
automatically detect the new reference val-
ues, e.g. if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
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 226).
X Make sure that the key is in position 2in
the ignition lock.
The standard display appears in the multi-
function display (Y page 122). Operation
