Lowering the vehicle
G
WARNING
The wheels could work loose if the wheel nuts
and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
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 111 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 cargo compartment again.
X
Check the tire pressure of the newly mounted
wheel and adjust it if necessary.
Observe the recommended tire pressure
(

page 352).
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/tire combination
You can ask for information regarding permitted
wheel/tire combinations 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.
!
Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tires. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tires are mounted. Do not mount used tires if
you have no information about their previous
usage.
The recommended pressures for various oper-
ating conditions can be found:
R
on the Tire and Loading Information placard
on the B-pillar on the driver's side
R
in the tire pressure table in the fuel filler flap
