Advice
tyres wear too quickly, have the wheel align-
ment
c
hec
ked at a specialised workshop.
WARNING
If you notice unusual vibration or the car pulls
to one side whi
le driving, this may indicate
that one of the tyres is damaged.
●
Reduce speed immediately and stop, while
observing the highway code.
●
Check the wheels and tyres for damage.
●
Never carry on driving on worn tyres or
wheels. Request qualified assistance immedi-
ately.
●
If there is no visible exterior damage, drive
slowly and carefully to the nearest special-
ised workshop and have the vehicle checked.
Tyre monitor system*

The tyre control lamp compares wheel revolu-
tion
s
and w
ith it, the wheel diameter of each
wheel using the ESC. If the diameter of a
wheel changes, the tyre control lamp
lights up. The wheel diameter changes when:
●
Tyre pressure is insufficient.
●
The tyre structure is damaged.
●
The vehicle is unbalanced because of a
load.
●
The wheels of one axle are under more
pressure (for example, driving with a trailer or
on steep slopes).
●
The vehicle is fitted with snow chains.
●
The temporary spare wheel is fitted.
●
The wheel on one axle is changed.
Tyre pressure adjustment
On adjusting tyre pressure or changing one
or more wheels, the ››› Fig. 176 button must
be kept pressed down, with the ignition on,
until an acoustic signal is heard.
If the wheels are under excessive load (for ex-
ample, driving with a trailer or heavy load),
the tyre pressure must be increased to the
recommended value for a full load (see the
sticker on the inside of the fuel flap). If the
tyre monitor system button is pressed down,
the new tyre pressures are confirmed.
The tyre pressure control lamp lights up
If the tyre pressure of a wheel is much lower
than the value set by the driver, then the tyre
pressure control lamp ›››
will light up.
WARNING
●
When the tyre pr
essure control lamp lights
up, reduce speed immediately and avoid any
sudden turning or braking manoeuvre. Stop
when possible, and check the tyre pressure
and status.
●
The driver is responsible for maintaining
correct tyre pressures. For this reason, tyre
pressure must be regularly checked.
●
Under certain circumstances (e.g. when
driving in a sporty manner, in winter condi-
tions or on a dirt track) the tyre control lamp
may light up belatedly or may function incor-
rectly.
Note
If the battery is disconnected, the yellow
warning l
amp lights up after turning the
ignition on. This should turn off after a brief
journey.
