into account when checking the pressure of
warm tyres and only correct it if it is too low
for the current operating conditions.
Driving with tyre pressure that is too high or
too low can:
shorten the service life of the tyres
R
cause increased tyre damage
R
have a negative effect on handling charac-
R
teristics and thus the driving safety (e.g. by
causing aquaplaning)
i
The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle.

Environmental note
Check the tyre pressure regularly, at least
every 14 days.

WARNING
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. The table
on the inside of the fuel filler flap will help you
decide whether the tyre pressures should be
corrected.
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. Do not
make any sudden steering movements when
doing so.
If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you when
the pressure drops in one or more of the
tyres. The tyre pressure monitor only func-
tions if the correct sensors are fitted to all
wheels.
Information on tyre pressures is displayed in
the multifunction display. After a few minutes
of driving, the current tyre pressure of each
tyre is shown in the multifunction display.
i
The tyre pressure values indicated by the
on-board computer may differ from those
measured at a filling station with a pressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tyre pres-
sure values indicated by a pressure gauge
are higher than those shown by the on-
board computer. In this case, do not reduce
the tyre pressures.
i
The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.

The current tyre pressure for each wheel will
be displayed in the multifunction display.
If the vehicle is parked for longer than
20 minutes and you then drive at less than
25 km/h, the Tyre pressure display
appears after several minutes driv‐
ing message appears.
After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the
pressure monitor active
sage is shown instead of the tyre pressure
