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 s ide whi

le driving, this may indicate
that one of the tyres is damaged.
● Reduce speed immediately and stop, while
obser
ving the highway code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or
wheels. Reque
st 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* 
Fig. 176
Centre console: tyre monitor system
b utt
on 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 wheel

s of one axle are under more
pres
sure (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.
Tyr
e 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 tyr e 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 s
porty 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
warnin g l

amp  lights up after turning the
ignition on. This should turn off after a brief
journey. 206

a)
The letters TIN refer to the tyre serial number.
Tyres with directional tread pattern
Tyres with directional tread pattern have
been designed to operate best when rotating
in only one direction. An arrow on the tyre
sidewall indicates the direction of rotation on
tyres with directional tread. Always observe
the direction of rotation indicated when
mounting the wheel. This guarantees opti-
mum grip and helps to avoid aquaplaning,
grip, noise and wear.
If the tyre is mounted in the opposite direc-
tion of rotation, drive with extreme caution,
as the tyre is no longer being used correctly.
This is of particular importance when the
road surface is wet. Change the tyre as soon
as possible or remount it with the correct di-
rection of rotation. Tyre load rating

ating code indicates the maximum

Wheel bolts
After the wheels have been changed, the
tightening torque of the wheel bolts should
be checked as soon as possible with a torque
wrench ››› . The tightening torque for steel
and al lo
y

wheels is 110 Nm. WARNING
● Check the ty

re pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● If the tightening torque of the wheel bolts
is t
oo low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque is too high, the wheel bolts and
threads can be damaged. Note
We recommend that you ask your Technical
Serv ic

e for information about appropriate
wheel, tyre and snow chain size. 213
