Raising the vehicle G
WARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is arisk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle. The following must be observed when raising
the vehicle:
R
to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz.Ift he jack is
used incorrectly, it could tip over while the
vehicle is raised.
R the jack is designed only to raise and hold
the vehicle for ashort time while awheel
is being changed. It is not suited for per-
forming maintenance work under the vehi-
cle.
R avoid changing the wheel on uphilla nd
downhill slopes.
R before raising the vehicle, secure it from
rolling awaybya pplying the parking brake
and inserting wheel chocks. Never disen-
gage the parking brake while the vehicle is
raised.
R the jack must be placed on afirm, flat and
non-slip surface. On aloose surface, a
large, load-bearing underlay must be used.
On aslippery surface, anon-slip underlay
must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as ajack underlay.O therwise, the
jack will no tbea ble to achiev eits load-
bearin gcapacity due to the restricted

WARNING
Oiled or greased wheel bolt sordamaged
wheel bolts/hub threads can cause th ewheel
bolt stoc omeloose .Asa result, you could
lose awheel while driving. There is arisk of
accident.
Never oil or grease wheel bolts. In the event
of damage to the threads, contact aqualified

Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always pay attention to the instructions and
safety notices in "Changing awheel"
(Y page 336).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-

X Stow the jack and the rest of the vehicle
tools in the boot again.
X Check the air pressure of the newly fitted
wheel and adjust accordingly.
Observe the recommended tyre pressure
(Y page 331).

with functioning sensors. Wheel and tyrec
ombinations General notes
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These are specially adapted to the control
systems, such as ABS or ESP
®
and are
marked as follows:
R MO =Mercedes-BenzO riginal
R MOE =Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 =Mercedes-BenzO riginal (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres
may only be usedonw heels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components.T his could result in dam-
age to the tyres or the vehicle.
Mercedes-Ben zaccepts no liability for
damag eresulting from the us eoftyres,
wheel soraccessorie sothe rthan those tes-
ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As aresult,
Mercedes-Ben zcannot guarante evehicle
safety if retreade dtyres are fitted. Do not
fit used tyres if you have no information
about their previous usage.
! Large wheels :the lower the section width
for acertain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as aresult of driving over obstacles
increases. Wheel and tyrec

Overview of abbreviations used in the follow-
ing tyre tables:
R BA: both axles
R FA: front axle
R RA: rear axle
You will find atable with recommended tyre
pressures for various operating conditions on
the inside of your vehicle's fuel filler flap. For
further information on tyre pressure, see
(Y page 331). Check tyre pressures regularly
and only when the tyres are cold.
Notes on the vehicle equipment –always fit
the vehicle:
R with tyre softhe same size on agiven axle
(left/right)
R with the same type of tyre satagiven time
(summer tyres, winter tyres, MOExtended
tyres)
Vehicles with MOExtende dtyre sare not
equipped with aTIREFIT kit at the factory. It
is therefore recommende dthat you addition-
ally equip your vehicle with aTIREFIT kit if you
fit tyre sthat do not feature run-flat charac-
teristics, e.g. winter tyres. ATIREFIT kit can
be obtained fro maqualified specialist work-
shop.
i Not all wheel/tyre combinations can be
mounted at the factory in all countries. 342
