The tyre pressure warning system does not
warn you of an incorrectly set tyre pressure.
Observe the notes on the recommended tyre
pressure (Y page 343).
The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure 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 haltb y braking carefully. Avoid
abrupt steering manoeuvres.
The function of the tyre pressure loss warning
system is limited or delaye dif:
R snow chains are fitted to you rvehicle'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, make sure that the tyre
pressures are set properly on all four tyres
for the respective operating conditions.
The recommended tyre pressures can be
found in the 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.
X Also observe the notes in the section on
tyre pressures (Y page 343).

R wheel wrench
Securing the vehicle against rolling
away If your vehicle is equipped with a wheel chock,
it can be found in the tyre-change tool kit
(Y page 323). The folding wheel chock is an additional
securing measure to prevent the vehicle from
rolling away, for example when changing a
