Replacing bulbs
Safety notes
Safe vehicle operation depends on proper
exterior lighting and signaling to a large
degree.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an
authorized Mercedes-Benz Center for
headlamp adjustment.
GWarning!
Bulbs and bulb sockets can be very hot. Allow
the lamp to cool down before changing a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you
Rtouch or move it when hot
Rdrop the bulb
Rscratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
iSince replacing bulbs is a technically
highly demanding process, we recommend
to have them replaced at an authorized
Mercedes-Benz Center.
iIf the headlamps or front fog lamps are
fogged up on the inside as a result of high
humidity, driving the vehicle a distance with
the lights on should clear up the fogging.

Replacing wiper blades
Safety notes
GWarning!
For safety reasons, switch off the wipers and
remove the SmartKey from the starter switch
(vehicles with KEYLESS-GO: Make sure the
vehicle’s on-board electronics have status 0)
before replacing a wiper blade. Otherwise, the
wiper motor could suddenly turn on and cause
injury.
GWarning!
Wiper blades are components that are subject
to wear and tear. Replace the wiper blades
twice a year, preferably in the spring and fall.
Otherwise the windshield will not be wiped
properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.
! Never open the hood when a wiper arm is
folded forward.
Hold on to the wiper when folding a wiper
arm back. If released, the force of the
impact from the tensioning spring could
crack the windshield.
Do not allow a wiper arm to contact the
windshield glass without a wiper blade
inserted.
Mercedes-Benz recommends that you have
this work carried out at an authorized
Mercedes-Benz Center.
XRemove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO:XMake sure the vehicle’s on-board
electronics have status 0 (Y page 86).

iVehicles without spare wheel are not
factory-equipped with the tools required for
a wheel change such as a jack or a wheel
wrench. Some tools required for a wheel
change are specific to your vehicle.
Contact an authorized Mercedes-Benz
Center to obtain the tools approved for
your vehicle. This section describes the
wheel change using the tools approved and
recommended for your vehicle.
Lifting the vehicleGWarning!
When jacking up the vehicle, only use the jack
which has been specifically approved by
Mercedes-Benz for your vehicle.
The jack is designed exclusively for jacking up
the vehicle at the jack take-up brackets built
into both sides of the vehicle. Make sure the
jack arm is fully seated in the jack take-up
bracket. The jack must always be vertical
when in use, especially on inclines or
declines.
The jack is intended only for lifting the vehicle
briefly for wheel changes. It is not suited for
performing maintenance work under the
vehicle. To help avoid personal injury, use the
jack only to lift the vehicle during a wheel
change.
Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under the
vehicle.
Always engage the parking brake firmly and
block the wheels with wheel chocks or other
sizeable objects before raising the vehicle
with the jack. Do not disengage the parking
brake while the vehicle is raised.
Make sure that the ground on which the
vehicle is standing and where you place the
jack is solid, level and not slippery. If
necessary, use a large underlay. On slippery
surfaces, such as tiled floors, you should use
a non-slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
to support the jack. Otherwise the jack may
not be able to achieve its load-bearing
capacity if it is not at its full height.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.XPrevent the vehicle from rolling away by
blocking wheels with wheel chocks or other
sizeable objects.
When your vehicle is equipped with a wheel
chock, it is included with the vehicle tool kit
( Y page 268). For information on setting up
the collapsible wheel chock, see
( Y page 270).
When changing a wheel on a level surface:
XPlace a wheel chock or other sizeable
object in front of and another wheel chock
or other sizeable object behind the wheel
that is diagonally opposite to the wheel
being changed.
Always try lifting the vehicle using the jack on
a level surface. However, should
circumstances require you to do so on a hill:
XPlace wheel chocks or other sizeable
objects on the downhill side in front of both
wheels on the side opposite to the side on
which the wheel is to be changed.GWarning!
Only jack up the vehicle on level ground or on
slight inclines/declines. Otherwise, the
vehicle could fall off the jack and injure you or
others.

take-up bracket.
If you do not position the jack correctly in the
jack take-up bracket, the vehicle can fall off
the jack and seriously or fatally injure you or
others.
! Do not position the jack on the body of
the vehicle, as this may cause damage to
the vehicle.
