Folding the exterior rear view mirrors
in and out automatically
When the corresponding function in the
control system is activated (
page 184):

The exterior rear view mirrors automat-
ically fold in as soon as the vehicle is
locked from the outside.

The exterior rear view mirrors automat-
ically fold out as soon as the vehicle is
unlocked and the driver’s or front pas-
senger door are subsequently opened.Synchronizing exterior rear view
mirrors
The power folding rear view mirrors may
have to be synchronized after the vehicle
battery has been disconnected or
discharged. If the exterior rear view
mirrors do not fold properly upon locking
or unlocking the vehicle although the
corresponding function in the control
system is activated (
page 184), do the
following:
Fold each exterior rear view mirror in
completely (
page 205).
Fold each exterior rear view mirror out
completely (
page 205).
When the exterior rear view mirrors fold
properly upon locking the vehicle, the
exterior mirrors are synchronized.
Otherwise repeat the above steps.
Warning!G
The auto-dimming function does not react if
incoming light is not aimed directly at sen-
sors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, when transporting cargo
which covers the rear window.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe the traffic
conditions and could cause an accident.
Warning!G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your
interior rear view mirror or glance over your
shoulder before changing lanes.
!Before you drive the vehicle through an
automatic car wash, fold in the exterior rear view
mirrors. Otherwise they may get damaged.

System self-check
Initially, after switching on the ignition,
malfunctions are detected and indicated
(the indicator lamps in the SOS button, the
Roadside Assistance button• and the
Information button¡ stay on longer
than 10 seconds or do not come on). The
message
Tele Aid Inoperative appears
in the multifunction display.Emergency calls
An emergency call is initiated auto-
matically following an accident in which
the emergency tensioning devices (ETDs)
or air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 324) for
instructions on initiating an emergency call
manually.
Once the emergency call is in progress, the
indicator lamp on the SOS button will
begin to flash. The message
Connecting Call appears in the multifunc-
tion display. When the connection is estab-
lished, the message
Call Connected
appears in the multifunction display.
All information relevant to the emergency,
such as the location of the vehicle (deter-
mined by the GPS satellite location sys-
tem), vehicle model, identification number
and color are generated.
iWhen a Tele Aid call has been initiated,
the COMAND system audio is muted and the
selected mode (radio, CD etc.) pauses.
The optional cellular phone (if installed) inserted
in cradle switches off. If you must use this
phone, we recommend that you use it only with
the vehicle at a standstill in a safe location.
Remove the phone from the cradle and place the
call. The navigation* system (if engaged) will
continue to run. The display in the instrument
cluster is available for use, and spoken com-
mands are only available by pressing the
RPT button on the COMAND system. A pop-up
window will appear in the COMAND system dis-
play to indicate that a Tele Aid call is in progress.

cellular phone inserted in the cradle switches on
again. A PIN entry might be necessary.

If the indicator lamps on the SOS button, on
the Roadside Assistance button, and/or on
the Information button remain illuminated
continuously in red and/or the message
Tele Aid Inoperative is displayed in the
multifunction display after the system
self-check, a malfunction in the system has
been detected.

above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.

Report the incident to the police.
The police will issue a numbered
incident report.
Pass this number on to the
Mercedes-Benz Response Center along
with your password issued to you when
you subscribed to the service.

Tele Aid system. Once the vehicle is
located, the Response Center will
contact the local law enforcement and
you. The vehicle’s location will only be
provided to law enforcement.
Garage door opener
The integrated remote control is capable of
operating up to three separately controlled
devices. It provides a convenient way to

other devices compatible with HomeLink
®
or some other systems.
Before the integrated remote control can
be used, it must be programmed to the

405 Operation
Vehicle care
Engine cleaning
Prior to cleaning the engine compartment
make sure to protect electrical compo-
nents and connectors from the intrusion of
water and cleaning agents.
Corrosion protection, such as
MB Anticorrosion Wax, should be applied
to the engine compartment after every
engine cleaning. Before applying, all con-
trol linkage bushings and joints should be
lubricated. 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 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 system (
page 208) or
the automatic climate control system*
(
page 222) to air recirculation mode.
If the vehicle is very dirty, prewash it
before running it through the automatic
car wash.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of water, and
a SmartKey with KEYLESS-GO* is in close
proximity, i.e. within approximately
3 ft (approximately 1 m), the vehicle could be
inadvertently locked or unlocked.
!Do not use scouring agents on these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the vehicle.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you may scratch or damage the paint.
!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 that the windshield wiper switch
is set to0 (
page 60). 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.
