Risk of accident
Check tyre pressure regularly, at least every
two weeks. If the tyre pressure is incorrect,
your vehicle's handling characteristics could
be altered or the tyre could explode.
Tyre pressure changes by approximately
0.1 bar for every 10 °C change in ambient
temperature.
If you measure the tyre pressure indoors
where the temperature differs from the
outside temperature, you will have to cor-
rect the measured value accordingly.
When the vehicle is driven, the tyre tem-
perature, and with it the tyre pressure, will
increase depending on the road speed and
the load on the tyres.
Tyre pressure loss warning system
While the vehicle is in motion the tyre pres-
sure loss warning system monitors the tyre
pressure set by evaluating the speed of the
individual wheels. The system can there-
fore recognise any significant loss of tyre
pressure in a wheel.
If the wheel speed changes due to declin-
ing tyre pressure, a corresponding warning
message will appear in the multi-function
display.
Operation of the tyre pressure loss warn-
ing system is limited or delayed if:
snow chains are fitted on your vehicle
there are winter road conditions
you are driving on a loose surface
(e.g. sand or gravel)
you have adopted a very sporty driving
style (driving on a bend at high speed
or driving with a high rate of accelera-
tion)
you are driving a heavy load

Risk of accident
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table in 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 the
tyre pressure, since a uniform pressure loss
in all four tyres cannot be identified by the
tyre pressure loss warning system.
The tyre pressure loss warning system is not
able to warn you of a sudden loss of pres-
sure, e.g. following penetration by a foreign
object.
If this occurs, bring the vehicle to a halt by
braking carefully. Do not make any sudden
steering movements when doing this.
Restarting the tyre pressure loss
warning system
Restart the tyre pressure loss warning sys-
tem if:
you have changed the tyre pressure
you have changed the wheels or tyres
you have fitted new wheels or tyres
