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 231) 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 multifunction display.
When the connection is established, the
message
Call connected appears in the
multifunction display. All information
relevant to the emergency, such as the
location of the vehicle (determined by the
GPS satellite location system), 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 con-
tinue to run. The display in the instrument cluster
is available for use, and spoken commands are
only available by pressing the RPT button on the
COMAND system. A pop-up window will appear
in the COMAND system display to indicate that a
Tele Aid call is in progress. After the Tele Aid call
has ended, the optional cellular phone inserted
in the cradle switches on again. A PIN entry
might be necessary.
Warning!G
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.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.

control
Step 1:
Switch on the ignition (page 39).
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
potential harm or damage. When program-
ming a garage door opener, the door moves
up or down. When programming a gate oper-
ator, 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.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health.
All exhaust gas contains carbon monoxide
(CO), and inhaling it can cause unconscious-
ness and possible death.
317 Operation
Vehicle care
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 to air recirculation
mode (
page 183).If the vehicle is very dirty, prewash it
before running it through the automatic
car wash.Ornamental moldings
For regular cleaning and care of
ornamental moldings, use a damp cloth.
!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 use caustic spray.
Otherwise the caustic spray will damage the
paint or ornamental moldings.
!Make sure that the windshield wiper switch
is set to0 (
page 58). 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.
iAfter running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 319). 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
cleaner. If in doubt whether an ornamental
molding is chrome-plated, contact an authorized
Mercedes-Benz Light Truck Center.

changing a bulb.
Keep bulbs out of reach of children.
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.

dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.

otherwise damage the LEDs or parts of the vehi-
cle. Only have the LEDs replaced at an autho-
rized Mercedes-Benz Light Truck Center.
