536 OperationVehicle careEngine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical compo-
nents and connectors from contact with
water and cleaning agents.
Corrosion protection, such as
MB Anticorrosion Wax, should be applied
to the engine compartment after every en-
gine cleaning. Before applying, all control
linkage bushings and joints should be lu-
bricated. The poly-V-belt and all pulleys
should be protected from any wax.
Vehicle washing
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the vehicle underbody, do
not forget to clean the inner sides of the
wheels.Hand-wash
Do not use hot water or wash your vehicle
in direct sunlight.
Only use a mild car wash detergent,
such as Mercedes-Benz approved Car
Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water.
Direct only a very weak spray towards
the ventilation intake.
Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clean water and thoroughly
dry with a chamois.
Do not allow cleaning agents to dry on
the finish.
Automatic car wash
You can have your vehicle washed in an au-
tomatic car wash from the start. Automatic
car washes without brushes are prefera-
ble.If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.
i
Vehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of water, and
a SmartKey with KEYLESS-GO* is in close prox-
imity, i.e. within approximately 3 ft (approxi-
mately 1 m), the vehicle could be inadvertently
locked or unlocked.
!
Do not clean your vehicle in an automatic
touchless car wash which uses caustic spray.
Otherwise the caustic spray will damage the
paint or ornamental moldings.
!
Due to the width of the vehicle, fold in
exterior rear view mirrors prior to running the ve-
hicle through an automatic car wash to prevent
damage to the mirrors.
Make sure that the windshield wiper switch is set
to0 (page 351). Otherwise, the rain sensor
could activate and cause the wipers to move un-
intentionally. This may lead to vehicle damage.
i
After running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 540). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.
When leaving the car wash, make sure that the
mirrors are folded out. Otherwise they may vi-
brate.
623 Practical hints
Replacing bulbs
Notes on bulb replacement
Only use 12-volt-bulbs of the same
type and with the specified watt rating.
Switch lights off before changing a bulb
to prevent short circuits.
Always use a clean lint-free cloth when
handling bulbs.
Your hands should be dry and free of oil
and grease.
If the newly installed bulb does not
come on, visit an authorized
Mercedes-Benz Center.
Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center.
the Bi-Xenon lamps
the front turn signal lamps
the front fog lamps
the additional turn signal lamps in the
exterior rear view mirrors
the parking and standing lamps
the front side marker lamps
the high mounted brake lamps
the brake, tail and rear standing lamps
the rear side marker lamps
the rear fog lamp
the rear turn signal lamps
the rear side marker lamps
the license plate lamps
Replacing bulbs for front lamps
Before you start to replace a bulb for a
front lamp, do the following first:
Turn the exterior lamp switch to M
(page 342).
Open the hood (
page 492) (except
for side marker lamps).
Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
touch or move it when hot
drop the bulb
scratch 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.
i
Have the headlamp adjustment checked
regularly.
626 Practical hintsReplacing bulbs
Insert bulb holder1 into guide in
headlamp. Wire2 must point down-
ward and to the right.
Turn bulb holder1 clockwise until it
engages and wire2 points downward
and to the left.

Take out bulb holder1.
Take bulb out of holder.
Insert new bulb into holder and press it
all the way down.
Insert bulb holder1 into guide in
headlamp.
The tab of the bulb holder must be po-
sitioned on the upper left-hand side
and wire3 must point downward and
to the left for the left headlamp, up-
ward and to the right for the right head-
lamp.
Turn bulb holder1 clockwise until it
engages and grip2 is in a horizontal
position.Additional turn signal lamp bulbs
The additional turn signal lamps in the ex-
terior rear view mirrors have LEDs.
If a malfunction occurs or LEDs fail to func-
tion, the entire turn signal unit must be re-
placed. Have the turn signal unit replaced
by an authorized Mercedes-Benz Center.
Front side marker lamp bulbs
Since replacing the side marker lamp bulbs
is a technically highly demanding process,
we recommend you have the side marker
lamp bulbs replaced by an authorized
Mercedes-Benz Center.
