The engine is equipped with a high-voltage
electronic control unit for the injection
system. Because of the high voltage it is
dangerous to touch any components of the
injection system (injectors, electrical wires)

with the engine running


while starting the engine


when the ignition is switched on

407 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
climate control (
page 208) or the au-
tomatic climate control (
page 222)
to air recirculation mode.
If the vehicle is very dirty, prewash it
before running it through the automatic
car wash.Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a damp cloth.
!
Do not clean your vehicle in an automatic
touchless car wash which use caustic spray.
Otherwise the caustic spray will damage the
paint or ornamental moldings.
!
If you want the gear position to remain inN
(for example when the vehicle is pulled through
a car wash)


do not remove the SmartKey from the starter
switch
or, when using KEYLESS-GO*


do not turn off the engine using the
KEYLESS-GO start/stop button* and open
the driver’s door.
Otherwise, the transmission will shift toP and
lock the wheels, preventing the vehicle from be-
ing pulled through a car wash.
!
Make sure that the windshield wiper switch
is set to0 (
page 61). 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
damage to the mirrors.
i
After running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 410). 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
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 Light Truck Center.

410 OperationVehicle careCleaning the windows and the wiper
blades
Fold the wiper arms forward until they
engage.

Clean the wiper blade inserts with a
clean cloth and detergent solution.

Use a soft, clean cloth and a mild win-
dow cleaning solution on all outside
and inside glass surfaces.
An automotive glass cleaner is recom-
mended.Light alloy wheels
If possible, clean wheels once a week.

Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light al-
loy wheels.
Warning!
G
For safety reasons, switch off wipers and re-
move SmartKey from starter switch
(vehicles with KEYLESS-GO*: Make sure the
vehicle’s on-board electronics have
status
0) before cleaning the windshield
and/or the wiper blades. Otherwise, the
wiper motor could suddenly turn on and
cause injury.
!
Do not pull on the wiper blade inserts. They
could tear.
!
Fold the windshield wiper arms back onto
the windshield before turning the SmartKey in
the starter switch or pressing the KEYLESS-GO
start/stop button (vehicles with KEYLESS-GO*).
Hold on to the wiper when folding the wiper arm
back. If released, the force of the impact from
the tensioning spring could crack the windshield.
!
To clean the window interior, do not use a
dry cloth, abrasives, solvents or cleaners con-
taining solvents. Do not touch the inside of the
front, rear or side windows and the power
tilt/sliding sunroof* or rear panorama roof with
hard objects such as an ice scraper or ring.
Doing so may damage the windows.
!
Only use acid-free cleaning materials. Acid
may cause corrosion or damage the clear coat.
!
The vehicle should not be parked for an ex-
tended period of time immediately after it has
been cleaned, especially not after the wheel rims
have been cleaned with wheel rim cleaner.
Wheel rim cleaners can lead to increased
corrosion of the brake disks and brake pads.
Non-approved wheel cleaners may also damage
the wheel paint if the car is not driven after
cleaning. Therefore, the vehicle’s brake system
should always be warmed-up before it is parked
after cleaning. To do so, please drive your vehicle
for several minutes to allow the brakes to dry.
When applying Mercedes-Benz approved Tire
Care and Mercedes-Benz approved Wheel Care
products, take care not to spray them on the
brake disks.

Wiper blades are components that are sub-
ject to wear and tear. Change the wiper
blades twice a year, preferably in the spring
and fall. Otherwise the windows will not be
properly wiped. As a result, you may not be
able to observe surrounding traffic condi-
tions and could cause an accident.

Never open the hood when the wiper arms
are folded forward.
Hold on to the wiper when folding the wiper arm
back. If released, the force of the impact from
the tensioning spring could crack the windshield.
Do not allow the wiper arms to contact the wind-
shield glass without a wiper blade inserted.
Make sure the wiper blades are properly
installed. Improperly installed wiper blades may
cause windshield damage.
For your convenience, we recommend that you
