Lowering the vehicle
GWARNING
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.
XPlace the ratchet wrench onto the hexagon
nut of the jack so that the letters ABare visi-
ble.
XTurn the ratchet wrench until the vehicle is
once again standing firmly on the ground.
XPlace the jack to one side.
XTighten the wheel bolts evenly in a crosswise pattern in the sequence indicated (: toA).
The tightening torque must be 110 lb-ft
(150 Nm) .
XTurn the jack back to its initial position.
XStow the jack and the rest of the vehicle tools
in the trunk again.
XCheck the tire pressure of the newly mounted
wheel and adjust it if necessary.
Observe the recommended tire pressure
(
Ypage 305).
iVehicles with a tire pressure control
system: all mounted wheels must be equip-
ped with functioning sensors for the tire pres-
sure monitor.
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:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires featuring run-flat characteristics)
RMO1 = 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:
Ron the Tire and Loading Information placard
on the B-pillar on the driver's side
Rin the tire pressure table in the fuel filler flap
Observe the notes on recommended tire pres-
sures under various operating conditions
(
Ypage 305).
Check tire pressures regularly, and only when
the tires are cold. Comply with the maintenance
