short time. This is rectified after a few
minutes of driving, and the tyre pressures
are displayed for the correct positions.
Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only if
they have the same dimensions: for example
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 recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist 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. Winter driving
Points to remember
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 302). Winter tyres
Use winter tyres at temperatures below
+7 ˚C and in wintry road conditions. Only
winter tyres displaying the isnowflake
symbol in addition to the M+S marking pro-
vide optimum grip in wintry road conditions.
Only these tyres will allow the ABS, ESP ®
and
4MATIC* driving systems to function opti-
mally in winter, as these tyres have been
designed specifically for driving in snow.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with a tread depth of less than
4 mm must be replaced immediately. They are
no longer suitable for winter use and can no
longer provide sufficient grip. This could
cause you to lose control of your vehicle and
cause an accident.
Always observe the maximum permissible
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permissible speed than that 302

affected. H
Environmental note
Have the used TIREFIT kit disposed of profes-
sionally, e.g. at a Mercedes-Benz Service
Centre.
X Have the TIREFIT kit replaced every four
years at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre. Changing a wheel and fitting the
spare wheel*
G
Risk of accident
The wheel dimensions and tyre size of the
"Minispare" emergency spare wheel *are dif-
ferent from those of the damaged wheel.
Your vehicle's handling characteristics will
change when a "Minispare" emergency spare
wheel* is fitted. Adapt your style of driving
accordingly.
The "Minispare" emergency spare wheel*
may only be used for a short time. Do not
exceed the maximum speed of 80 km/h and
do not deactivate ESP ®
.
Never drive the vehicle with more than one
"Minispare" emergency spare wheel* fitted. G
Risk of accident
Have the "Minispare" emergency spare
wheel* or the spare wheel* replaced with a
new wheel as soon as possible at a qualified
specialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
Preparing the vehicle X
Prepare the vehicle as described
(Y page 373).
X Place the wheels in the straight-ahead posi-
tion.
X Remove the following items from the stow-
age well under the boot floor:
R
the "Minispare" emergency spare
wheel* or the spare wheel*
R the container with the wheel bolts for the
"Minispare" emergency spare wheel* or

Using wheel wrench :, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts com-
pletely.
Raising the vehicle G
Risk of injury
The jack is designed only to raise the vehicle
for a short time while a wheel is being
changed.
The vehicle must be placed on stands if you
intend to work under it.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar objects as a jack underlay.
The vehicle could otherwise fall off the jack
and seriously injure you.
Do not start the engine at any time while the
wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise the
vehicle as described, it could slip off the jack
(e.g. if the engine is started or a door or the
boot lid is opened or closed), and you could
be seriously injured. G
Risk of accident
If you fail to position the jack correctly, the
vehicle may:
R slip off the jack
R injure you or others
R be damaged Thus, it is important to make sure that the jack
is positioned correctly in the respective jack-
ing points. Before positioning the jack,
remove any dirt that may have collected in the
jacking points.
The jacking points for the jack are located
behind the wheel housings of the front wheels
and in front of the wheel housings of the rear
wheels. X

! Do not place wheel bolts in sand or dirt.
The threads of the wheel bolts and wheel
hubs could otherwise be damaged when
the bolts are tightened.
X Remove the wheel.
Fitting a new wheel G
Risk of accident
Replace damaged or corroded wheel bolts.
Never oil or grease wheel bolts. This could
cause the bolts to loosen in the wheel hub. G
Risk of accident
If a wheel hub thread is damaged, you must
not drive the vehicle any further. Consult a
qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required. Mercedes-Benz
recommends that you use a Mercedes-Benz
Service Centre or Service 24h for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at a qualified specialist workshop. G
Risk of accident
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benz recommends that you
only use wheel bolts which have been
approved for Mercedes-Benz and the respec-
tive wheel. Other bolts may work loose or
damage the brake system.
Do not tighten the wheel bolts completely
while the vehicle is still jacked up. The vehicle
could topple off the jack. Wheel bolts for:

Lower the vehicle. To do this, turn the crank
of the jack anti-clockwise until the vehicle
is standing firmly on the ground again.
X Place the jack to one side. X
Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indica-
ted (: toA). The tightening torque is
150 Nm. G
Risk of accident
Have the tightening torque checked immedi-
ately after a wheel is changed. The wheels
could work loose if they are not tightened to
a torque of 150 Nm.
X Turn the jack back to its initial position and
store it and the rest of the vehicle tool kit
