Lowering the vehicle
G
WARNING
The wheels could come loose if the wheel
bolts or wheel nuts are not tightened to the
prescribed tightening torque. There is a risk of
an accident.
Ensure that the wheel bolts or wheel nuts are
tightened to the prescribed tightening torque.
If you are not sure, do not move the vehicle.
Contact a qualified specialist workshop and
have the tightening torque checked immedi-
ately.
!
Mercedes-AMG vehicles with a collapsi-
ble spare wheel: before lowering the vehicle,
inflate the collapsible spare wheel with the
tire inflation compressor. The wheel rim could
otherwise be damaged.
X
Place the ratchet wrench onto the hexagon
nut of the jack so that the letters AB are visi-
ble.
X
Turn the ratchet wrench until the vehicle is
once again standing firmly on the ground.
X
Place the jack to one side.
X
Tighten the wheel bolts evenly in a crosswise
pattern in the sequence indicated (: to A).
The tightening torque must be 110 lb-ft
(150 Nm).
X
Turn the jack back to its initial position.
X
Stow the jack and the rest of the tire-change
tool kit in the stowage well under the cargo
compartment floor again.
X
Check the tire pressure of the newly mounted
wheel and adjust it if necessary.
Observe the recommended tire pressure
(Y page 355).
When you are driving with the collapsible spare
wheel mounted, the tire pressure loss warning
system or the tire pressure monitor cannot func-
tion reliably. Only restart the tire pressure loss
warning system or tire pressure monitor when
the defective wheel has been replaced with a
new wheel.
Vehicles with a tire pressure control sys-
tem: all installed wheels must be equipped with
functioning sensors.
Wheel and tire combinations
Information regarding permitted wheel/tire
combinations can be found at an authorized
Mercedes-Benz Center.
!
For safety reasons, Mercedes-Benz recom-
mends that you only use tires and wheels
which have been approved by Mercedes-Benz
specifically for your vehicle.
These tires have been specially adapted for
use with the control systems, such as ABS or
ESP
®
, and are marked as follows:
R
MO = Mercedes-Benz Original
R
MOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
R
MO1 = Mercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with a load, tire dimension variations
could cause the tires to come into contact
with the bodywork and axle components. This
could result in damage to the tires or the vehi-
cle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Information on tires, wheels and approved
combinations can be obtained from any quali-
fied specialist workshop.
