Useful features
Garage door opener*
The integrated remote control is capable of
operating up to three separately controlled
devices. It provides a convenient way to re-
place up to three hand-held remote con-
trols used to operate devices such as
garage door openers, gate openers, or oth-
er devices compatible with HomeLink
® or
some other systems.
Before the integrated remote control can
be used, it must be programmed to the ga-
rage door opener, gate operator or other
device you wish to operate. See the follow-
ing instructions for programming informa-
tion.

Warning!G
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage. When programming
a garage door opener, the door moves up or
down. When programming a gate operator,
the gate opens or closes.
Do not use the integrated remote control
with any garage door opener that lacks
safety stop and reverse features as required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an object
– signaling the door to stop and reverse –
does not meet current U.S. federal safety
standards.
When programming a garage door opener,
park the vehicle outside the garage.


367 Operation
Vehicle care
Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are prefera-
ble.
To protect the filter system, switch the
automatic climate control to air recir-
culation mode (
page 265).
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a damp cloth.Headlamps, tail lamps, side markers,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo, with plenty of water.
!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.
!Make sure the windshield wiper switch is
set to0 (
page 117). Otherwise, e.g. the rain
sensor* could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent dam-
age to the mirrors.
iAfter running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 368). 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 the mir-
rors are folded out. Otherwise they may vibrate.
!Do not use chrome cleaner on ornamental
moldings. Although ornamental moldings may
have chrome appearance, they could be made of
anodized aluminum that will be damaged when
cleaned with chrome cleaner. Instead, use a
damp cloth to clean those ornamental moldings.
For very dirty ornamental moldings of which you
are sure are chrome-plated, use a chrome clean-
er. If in doubt whether an ornamental molding is
chrome-plated, contact an authorized
Mercedes-Benz Center.
!Only use window cleaning solutions that are
suitable for plastic lamp lenses. Window clean-
ing solutions which are not suitable may damage
the plastic lamp lenses of the headlamps. There-
fore, do not use abrasives, solvents or cleaners
that contain solvents.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry
cloth or sponge.
Otherwise you may scratch or damage the lens
surface.

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 at an authorized
Mercedes-Benz Center.

rior rear view mirrors

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
positionM (
page 108).
Open the hood (page 325).
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.!Do not replace the LEDs yourself. You could
otherwise damage the LEDs or parts of the
vehicle. Only have the LEDs replaced at an au-
thorized Mercedes-Benz Center.
