of the vehicle interior (when windows and
tilt/sliding sunroof* or tilt/sliding panel*
are closed).
Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving
through a tunnel). This setting cuts off the
intake of outside air and recirculates the
air in the passenger compartment.

Fogged windows impair visibility, endanger-
ing you and others. If the windows begin to
fog on the inside, switching off the air
recirculation mode immediately should clear
interior window fogging. If interior window
fogging persists, make sure the air

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
!To avoid damage to the windshield wipers or
hood, never open the hood if the wiper arms are
folded forward away from the windshield.

413 Operation
Vehicle care
Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a use damp cloth.Headlamps, brake lamps, tail lamps,
side markers, turn signal lenses
Use a mild car wash detergent, such
as Mercedes-Benz approved Car
Shampoo, with plenty of water.
!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
being pulled through a car wash.
!Make sure that the windshield wiper switch
is set to0 (
page 61). Otherwise, 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.
iAfter running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 415). 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 damp
cloth to clean those ornamental moldings.
Very dirty ornamental moldings of which you are
sure are chrome-plated, use a chrome cleaner.
If in doubt whether an ornamental molding is
chrome-plated, contact an authorized
Mercedes-Benz Light Truck 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.

Vehicle care
Cleaning the Rear View Camera lens*
1Camera lens
Only use clean water and a soft,

An automotive glass cleaner is recom-
mended.
!Do not clean the camera and the area
around the camera:

with a high-pressure cleaner

with a dry cloth and high pressure

with aggressive cleaning agents
You could otherwise damage the camera.
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
status0) 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 with hard objects
such as an ice scraper or ring. Doing so may
damage the windows.

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.
