Cleaning the vehicle parts
Cleaning the wheels
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
!Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after cleaning.
Braking heats the brake discs and the brake
pads/linings, thus drying them. The vehicle
can then be parked.
Cleaning the windows
GWARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
!Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring. There
is otherwise a risk of damaging the windows.
!Clean the water drainage channels of the
windshield and the rear window at regular
intervals. Deposits such as leaves, petals and pollen may under certain circumstances pre- vent water from draining away. This can lead
to corrosion damage and damage to elec-
tronic components.
XClean the inside and outside of the windows
with a damp cloth and a cleaning product that
is recommended and approved by Mercedes-
Benz.
Cleaning wiper blades
GWARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
!Do not pull the wiper blade. Otherwise, the
wiper blade could be damaged.
!Do not clean wiper blades too often and do
not rub them too hard. Otherwise, the graph-
ite coating could be damaged. This could
cause wiper noise.
!Hold the wiper arm securely when folding
back. The windshield could be damaged if the
wiper arm smacks against it suddenly.
XFold the windshield wiper arms away from the
windshield (Ypage 126).
XCarefully clean the wiper blades with a damp
cloth.
XFold the windshield wiper arms back again
before switching on the ignition.
Cleaning the exterior lighting
!Only use cleaning agents or cleaning cloths
which are suitable for plastic light lenses.
Unsuitable cleaning agents or cleaning cloths
could scratch or damage the plastic light len- ses.
XClean the plastic lenses of the exterior light-
ing using a wet sponge and a mild cleaning
agent, e.g. Mercedes-Benz car shampoo or
cleaning cloths.
338Care
Maintenance and care

XFold both plates upwards:.
XFold out lower plate;.
XGuide the lugs on the lower plate fully into the
openings in base plate =.
XPlace chocks or other suitable items under
the front and rear of the wheel that is diago-
nally opposite the wheel you wish to change.
Raising the vehicle
GWARNING
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 a risk 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 jack is designed exclusively for jacking
up the vehicle at the jacking points. Other-
wise, your vehicle could be damaged.
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. If used incorrectly, the
jack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It must not be used for performing
maintenance work under the vehicle.
RAvoid changing the wheel on uphill and down- hill slopes.
RBefore raising 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 a firm, flat and
non-slip surface. On a loose surface, a large,
flat, load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
RDo not use wooden blocks or similar objects
as
a jack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
RMake sure that the distance between the
underside of the tires and the ground does not
exceed 1.2 in (3 cm).
RNever place your hands and 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 a door or the trunk lid
when the vehicle is raised.
RMake sure that no persons are present in the
vehicle when the vehicle is raised.
Vehicles with alloy wheels and hub caps: the
wheel bolts are covered by a hub cap. Before you
can unscrew the wheel bolts, you must remove
the hub cap. Two different variants can be instal- led.
Vehicles with plastic hub cap:
XTo remove: turn the center cover of hub
cap :counter-clockwise and remove.
XTo install: before installing, ensure that hub
cap :is in the open position. To do this, turn
the center cover counter-clockwise.
XPosition hub cap :and turn the center cover
clockwise until hub cap :engages physically
and audibly.

Removing a wheel
!Mercedes-AMG vehicles with ceramic-
brake disc: during removal and repositioning
of the wheel, the wheel rim can strike the
ceramic-brake disc and damage it. Therefore,
you should proceed carefully and get a sec-
ond person assist to you. Alternatively, you
can use a second alignment bolt.
!Do not place wheel bolts in sand or on a dirty
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 uppermost wheel bolt com-
pletely.
XScrew alignment bolt :into the thread
instead of the wheel bolt.
XUnscrew the remaining wheel bolts fully.
XRemove the wheel.
Mounting a new wheel
GWARNING

wheel bolts/hub threads can cause the wheel bolts to come loose. As a result, you could
lose a wheel while driving. There is a risk of
accident.
Never oil or grease wheel bolts. In the event of
damage to the threads, contact a qualified
specialist workshop immediately. Have the
damaged wheel bolts or hub threads
replaced/renewed. Do not continue driving.
GWARNING
If you tighten the wheel bolts or wheel nuts
when the vehicle is raised, the jack could tip
over. There is a risk of injury.
Only tighten the wheel bolts or wheel nuts
when the vehicle is on the ground.
Always pay attention to the instructions and
safety notes in the "Changing a wheel" section
(
Ypage 379).

sons, Mercedes-Benz recommends that you
only use wheel bolts which have been approved for Mercedes-Benz vehicles and the respective
wheel.
!Mercedes-AMG vehicles with ceramic-
brake disc: during removal and repositioning
of the wheel, the wheel rim can strike the
ceramic-brake disc and damage it. Therefore,
you should proceed carefully and get a sec-
ond person assist to you. Alternatively, you
can use a second alignment bolt.

Wheel-tire combination
You can ask for information regarding permitted
wheel-tire co mbinations at an authorized
Mercedes-Benz Center.
!For safety reasons, Mercedes-Benz recom-
men dsthat you only use tires and wheels
whic h 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 adverselyaffected. In addition, when
