The pressure of warm tyres should only be
corrected if it is too low for the current oper-
ating conditions.
Driving with tyre pressure that is too high or
too low can:
shorten the service life of the tyres
R
increase the likelihood of tyre damage
R
have a negative effect on handling charac-

teristics (e.g. by causing aquaplaning)

The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
You can, however, also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle.
H Environmental note
Check the tyre pressure regularly, at least
every 14 days.
Tyre pressure loss warning system
G Risk of accident
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
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 loss warning system 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.
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

system is limited or delayed if:

R
you adopt a very sporty driving style (cor-

vehicle or on the roof)
