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.
While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appear in the multi-function dis-
play.
The function of the tyre pressure loss warning
system is limited or delayed if:
R
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 (cor-
nering at high speeds or driving with high
rates of acceleration)
R
you are towing a very heavy or large trailer
R
you are driving with a heavy load (in the
vehicle or on the roof)
Restarting the tyre pressure loss warn-
ing system
Restart the tyre pressure loss warning system
if you have:
R
changed the tyre pressure
R
changed the wheels or tyres
R
fitted new wheels or tyres
X
Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap
to ensure that the tyre pressure in all four
tyres is set correctly for the operating con-
ditions concerned.

Also observe the notes in the section on
tyre pressures (

page 229).
G
Risk of accident
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.
A tyre with insufficient pressure results in
an instability of the vehicle when driving,
thus increasing the risk of an accident.

Make sure that the key is in position 2 in
the ignition lock.

function display (
