The tyre pressure values stored at the last
restart will continue to be monitored. Interchanging the wheels
G
Risk of accident
Interchange the fron tand rear wheels only if
they have the same dimensions :for example
size, offset ,etc.
After awheel is changed, have the tightening
torque checked at aspecialist workshop that
has the necessary specialist knowledge and
tools to carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Servic eCentre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
The wheels could work loose if they are not
tightened to atorque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correc tsize which have been approved for
Mercedes-Benz vehicles.
The wear patterns on the fronta nd rear tyres
differ, depending on the operating conditions.
Interchange the wheels before aclear wear
patter nhas formed on the tyres. Frontt yres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size fronta nd
rear wheels you can interchange the wheels
every 5,000 km to 10,00 0kmdepending on
the degree of tyre wear. Do not reverse the
direction of tyre rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time awheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system*. Winter driving
Points to remember
Have your vehicle winterproofed at aqualified
specialist workshop, e.g. at aMercedes-Benz
Servic eCentre, at the onset of winter.
Observe the notes in the "Changing awheel"
section (Y page 189). Winter tyres
Use winter tyres at temperatures below
+7 ˚C and in wintry road conditions. Only
winter tyres displaying the 004Dsnowflake
symbol in addition to the M+S markin gpro-
vide optimum grip in wintry road conditions.
Only these tyres will allow the ABS and ESP
driving systems to function optimally in win-
ter, as these tyres have been designed spe-
cifically for driving on 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 atread depth of less than
4mmm ust 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
of the vehicle, affix an appropriate warning
sign in the driver's field of vision. This can be
obtained at aqualified specialist workshop,
e.g. from aMercedes-Benz Servic eCentre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanen tSpeedtronic 37
to the maxi-
mum permissible speed for the winter tyres
(Y page 135).

Tighten the wheel bolts until they are fin-
ger-tight.

tight.
Lowering the vehicle X
Lower the vehicle. To do this, turn the crank
of the jack anti-clockwise until the vehicle
is once again standin gfirmly on the ground.
X Place the jack to one side. X
Tighten the wheel bolts evenly in across-
wise patter ninthe sequence indica-
ted (0046 to0086). The tightening torque is
130 Nm. G
Risk of accident
Have the tightening torque checked immedi-
ately after awheel is changed. The wheels
could work loose if they are not tightened to
at orque of 130 Nm.
X Turn the jack back to its initial position and
store it together with the rest of the vehicle
tool kit in the stowage well under the boot
floor.

i When you are driving with the "Minispare"
emergenc yspare wheel* fitted, the tyre
pressure loss warning system* cannot
function reliably. MOExtended run-flat system*
The MOExtended run-flat system may only be
used in conjunction with the activated tyre
pressure loss warning system.
! The maximum permissible distanc ewhich
can be driven in run-flat mode depends on
the load in the vehicle. It is 80 km if the
vehicle is partially laden and 30 km if fully
laden. 272
