!On vehicles equipped withatire pressure
monitor, electronic componentsa re located
in the wheel.
Tire-mounting tools should not be used near
the valve. This could damage the electronic
components.
Only have tires changed at aqualified spe-
cialist workshop.
Alwayso bserve the instructionsa nd safety
notes under "Installing awheel" (
Ypage 270).
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
On vehicles that have the same size front and
rear wheels, you can rotate the wheels accord-
ing to the intervals in the tire manufacturer's
warranty book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3,000 to 6,000 miles (5,000 to
10,000 km). Depending on tire wear, this may
be required earlier. Do not change the direction
of wheel rotation.
Cleant he contact surfaces of the wheel and the
brake disc thoroughly every time awheel is rota-
ted. Check the tire pressure and reactivate the
tire pressure monitor if necessary (
Ypage 259).
Direction of rotation
Tires with aspecified direction of rotation have
additional benefits, e.g. if there is arisk of hydro-
planing. You will only gain these benefits if the
correct direction of rotation is observed.
An arrow on the sidewall of the tire indicates its
correct direction of rotation.
You may mount the spare wheel against the
direction of rotation. Adhere to the time restric-
tion on use as well as the speed limitation speci-
fied on the spare wheel.
Storing wheels
Store tires that are not being used in acool, dry
and preferably dark place. Protect the tires from
oil, grease, gasoline and diesel.
Mounting awheel
Preparing the vehicle
GWARNING
When you remove the spare wheel from the
spare wheel bracket, the vehicle’s weight dis-
tribution changes. If the vehicle is already
raised, the jack could tip over. There is arisk
of injury.
Remove the spare wheel from the spare wheel
bracket before lifting the vehicle.
XStop the vehicle on solid, non-slippery and
level ground.
XApply the parking brake.
XBring the front wheels into the straight-ahead
position.
XShift the automatic transmission to position

Observe the following when raising the vehi-
cle:
RTo raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz.Ifused incorrectly, the
jack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold the
vehicle for ashort time while awheel is being
changed. It must not be used for performing
maintenance work under the vehicle.
RAvoid changin gthe wheel on uphill and down-
hill slopes.
RBeforer aising the vehicle, secure it from roll-
ing away by applying the parking brake and
inserting wheel chocks. Do not disengage the
parking brake while the vehicle is raised.
RThe jack must be placed on afirm, flat and
non-slip surface. On aloose surface, alarge,
flat, load-bearing underlay must be used. On a
slippery surface, anon-slip underlay must be
used, e.g. rubber mats.
RDo not use wooden blocks or similar objects
as ajack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
RMake sure that the distanc ebetween the
underside of the tires and the ground does not
exceed 1.2 in (3 cm).
RDo not place your hands or feet under the
raised vehicle.
RDo not lie under the vehicle.
RDo not start the engine when the vehicle is
raised.
RDo not open or close adoor when the vehicle
is raised.
RMake sure that no persons are present in the
vehicle when the vehicle is raised.
XUsing lug wrench :,loosen the bolts on the
wheel you wish to change by about one full
turn .Don ot unscrew the bolts completely.
XAssemble the pump lever for the jack from the
vehicle tool kit.
XTurn lowering screw =on the jack clockwise
as far as it will go using notch ;on the pump
lever.
Pressure release screw =is closed.
iDo not turn pressure release screw =by
more than one to two revolutions. Otherwise,
hydraulic fluid could escape.
XPosition jack Avertically under the jacking

tion under axle carrier tube ?.The front or
rear axle must sit securely in the recess of
jack A.
XKeep pumping until axle carrier tube ?sits
securely in the recess of jack Aand the base
of the jack lies evenly on the ground.
Ensure that the jack is located vertically under
the jackingp oint.
XRaise the vehicle by pumping until the tire is
no more than 1.2 in (3 cm) off the ground.
Removingawheel
!Do not place wheel bolts in sand or on adirty
surface. The bolt and wheel hub threads could
otherwise be damaged when you screw them
in.
When mounting/removing wheels, and for as
long as the wheels are removed, avoid applying
any external force on the brake disks. This could impair the level of comfort when braking.
XUnscrew the wheel bolts.
XRemove the wheel.
Mounting anew wheel
GWARNING
Oiled or greased wheel bolts/wheel nuts and
damaged wheel bolt/wheel nut/wheel hub
threads can cause wheel bolts/wheel nuts to
come loose. As aresult, you could lose a
wheel while driving. There is arisk of an acci-
dent.
Never oil or grease wheel bolts/wheel nuts. In
the event of damage to the threads, contact a
qualified specialist workshop immediately.
Have the damaged wheel bolts/wheel nuts or
hub threads replaced/renewed. Do not con-
tinue driving.
GWARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is arisk of injury.

!To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.
Always pay attention to the instructions and
safety notes in the "Changing awheel" section
(
Ypage 269).
Only use wheel bolts that have been designed
for the wheel and the vehicle. For safety rea-
sons, Mercedes-Benzr ecommends that you
only use wheel bolts which have been approved
for Mercedes-Benzv ehicles and the respective
wheel.
XClean the wheel and wheel hub contact sur-
faces.
XPlace the new wheel on the wheel hub and
push it on.
XTighten the wheel bolts until they are finger-
tight.
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 arisk of accident.
Have the tightening torque immediately
checked at aqualified specialist workshop
after awheel is changed.
XSlowly open the pressure release screw on
the jack using the pump lever by approx-
imately one full turn and carefully lower the
vehicle (
Ypage 270).
XYou can put the jack aside.
XTighten the wheel bolts evenly in acrosswise
pattern in the sequence indicated (: toA).
