G
Risk of accident
Interchange the front and rear wheels only
if they have the same dimensions: for exam-
ple size, offset, etc.
After every wheel interchange/change,
have the tightening torque checked at a
qualified specialist workshop that has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a torque of 150 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre. Interchange the wheels every 5,000 km to
10,000 km depending on the degree of tyre
wear, provided that the vehicle has the same
size front and rear tyres. Do not reverse the
direction of tyre rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure moni-
tor*.
! On vehicles fitted with a tyre pressure
monitor*, electronic components are loca-
ted in the wheel.
Tyre fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the wheels interchanged/
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
i Vehicles with a tyre pressure monitor*
If the positions of the wheels on the vehicle
are changed, the tyre pressure may be tem-
porarily displayed at the wrong position.
This is rectified after a few minutes of driv-
ing, and the tyre pressures are displayed
for the correct positions. Operation

Driving
tips 232
If you intend to fit snow chains, please bear
the following points in mind:
R Snow chains cannot be fitted to all wheel/
tyre combinations.
R Snow chains must not be fitted to emer-
gency spare wheels, e.g. the "Minispare" or
collapsible emergency spare wheel.
R Fit snow chains only in pairs and only to the
rear wheels. Comply with the manufactur-
er's installation instructions.
On vehicles with the AIRMATIC package*, you
may only drive at raised vehicle level if snow
chains have been fitted (Y page 156).
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
when
pulling away with snow chains fitted
(Y page 58). This way you can allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action). Winter driving
G
Risk of accident
Do not shift down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Shift the selector lever to N.
X Try to bring the vehicle under control using
corrective steering. Driving tips
Rolling with the engine switched off
G
Risk of accident
Do not switch off the engine while the vehi-
cle is in motion.
There is no power assistance for the steer-
ing or the service brake when the engine is
not running.
Steering and braking require significantly
more effort and you could lose control of
the vehicle and cause an accident as a
result. Braking
G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. G
Risk of accident
Make sure that other road users are not
endangered by your braking. Operation

Risk of injury
The jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed.
If you are carrying out work on the vehicle,
you must use stands.
