Important safety notes
The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe
the notes on the recommended tyre pressure
(
page 307).
Y
The tyre pressure loss warning does not replace
the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres-
sure loss warning system.
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 carefully. Avoid abrupt steering
manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
snow chains are fitted to your vehicle's tyres.
R
road conditions are wintry.
R
you are driving on sand or gravel.
R
you adopt a very sporty driving style (corner-
R
ing at high speeds or driving with high rates of
acceleration).
you drive with a heavy load.

Restarting the tyre pressure loss warn-
ing system
Restart the tyre pressure loss warning system if
you have:
changed the tyre pressure
R
changed the wheels or tyres
R
fitted new wheels or tyres
R
Before restarting, make sure that the tyre

pressures are set properly on all four tyres for
the respective operating conditions. The rec-
ommended tyre pressures can be found in the
tyre pressure table on the fuel filler flap.
The tyre pressure loss warning system can
only give reliable warnings if you have set the
correct tyre pressure. If an incorrect tyre
pressure is set, these incorrect values will be
monitored.

Tyre pressure monitor
General notes
If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that moni-
tor the tyre pressures in all four tyres. The tyre
pressure monitor warns you if the pressure
drops in one or more of the tyres. The tyre pres-
sure monitor only functions if the corresponding
sensors are fitted to all wheels.
Information on tyre pressures is shown in the
multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre is
shown in the
Service
Service
menu of the multifunction
display.
