extra care. Refit the normal road wheel as
soon as
po
ssible. Wheel bolts
The design of wheel bolts is matched to the
rims. If diff
er
ent wheel rims are fitted, the
correct wheel bolts with the right length and
correctly shaped bolt heads must be used.
This ensures that wheels are fitted securely
and that the brake system functions correctly.
In certain circumstances, you should not use
wheel bolts from a different vehicle, even if it
is the same model ››› page 255. WARNING
If the wheel bolts are not tightened correctly,
the wheel c ou
ld become loose while driving.
Risk of accident.
● The wheel bolts must be clean and turn
eas
ily. Never apply grease or oil to them.
● Use only wheel bolts which belong to the
wheel.
● If the pr
escribed torque of the wheel bolts
is t
oo low, they could loosen whilst 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. CAUTION
The prescribed tightening torque for wheel
bolt s
for steel and alloy wheels is 120 Nm. Tyre monitoring indicator*

on. The tyre monitoring system compares wheel
r
ev
o
lutions alongside the wheel diameter of
each wheel, with help from the ESC. If the di-
ameter of a wheel changes, the tyre monitor-
ing indicator lights up . The wheel diame-
ter 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
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.
Tyr
e pressure adjustment
After modifying tyre pressure or changing any
wheels, the new tyre pressure must be stored
in the Easy Connect system with the but-
t on and the S
ET
TINGS function button

page 33.
You can also press and hold down the
››› Fig. 241 button 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 back of the left front door
frame). 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.
