Control and operation of radio transmitters
MCS, radio and telephone
1 Observe all legal requirements.
Telephones and two-way radio
Radio transmitters, such as a portable telephone or a
citizens band unit should only be used inside the
vehicle if they are connected to an antenna that is
installed on the outside of the vehicle.
Refer to the radio transmitter operation instructions
regarding use of an external antenna.
Wa r n i n g !
Please do not forget that your primary
responsibility is to drive the vehicle. Only operate
the MCS, radio or telephone
1 if road and traffic
conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is covering
a distance of approximately 50 feet (approximately
14 m ) e v e r y s e c o n d .
Wa r n i n g !
Never operate radio transmitters equipped with a
built-in or attached antenna (i.e. without being
connected to an external antenna) from inside the
vehicle while the engine is running. Doing so could
lead to a malfunction of the vehicle’s electronic
system, possibly resulting in an accident and
personal injury.

The first 1 000 miles (1 500 km)
The more cautiously you treat your vehicle during the
break-in period, the more satisfied you will be with its
performance later on. Therefore, drive your vehicle
during the first 1 000 miles (1 500 km) at moderate
vehicle and engine speeds.
During this period, avoid heavy loads (full throttle
driving) and excessive engine speeds.
Avoid accelerating by kickdown. It is not recommended
to brake the vehicle by manually shifting to a lower gear.
We recommend that you select positions “3”, “2” or “1”
only at moderate speeds (for hill driving).
After 1 000 miles (1 500 km) speeds may be gradually
increased to the permissible maximum. Maintenance
Approximately 30 days or 2 000 miles
(Canada: 2000 km) prior to the next recommended
service, the remaining distance or days are displayed in
the multifunction indicator. See Flexible Service System
(FSS) on page 87.
We strongly recommend that you have your vehicle
serviced by your authorized Mercedes-Benz Light Truck
Center, in accordance with the Service Booklet at the
times called for by the FSS.
Failure to have the vehicle maintained in accordance
with the Service Booklet at the designated times /
mileage may result in vehicle damage not covered by
the Mercedes-Benz Limited Warranty.
Check regularly and before a long trip, see page 215.

Tele Aid
Important!
The initial activation of the Tele Aid system may only be
performed by completing the subscriber agreement and
placing an acquaintance call using the “SOS” button.
Failure to complete either of these steps will result in a
system that is not activated. If the system is not
activated the indicator lamp in the “SOS” button stays
on after turning electronic key in starter switch to
position 2 and the message “TELE AID – NOT
ACTIVATED” will be shown in the MCS display for
approx. 10 seconds.
If you have any questions regarding activation, please
call the Response Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
( Tele matic Alarm Identification on Demand)
The Tele Aid system consists of three types of response;
automatic and manual emergency, roadside assistance
and information. The Tele Aid system is operational providing that the
vehicle’s battery is charged, properly connected, not
damaged and cellular and GPS coverage is available.
The speaker volume of a Tele Aid call can be adjusted
using the volume control on the MCS unit. To activate,
press the “SOS” button, the Roadside Assistance
button • or the Information button ¡, depending
on the type of response required.
Shortly after the completion of your Acquaintance Call,
you will receive a user ID and password via first call
mail. By visiting www.mbusa.com and selecting
“Tele Aid” (USA only), you will have access to account
information, remote door unlock, Info Services
* profile
and more.
* OptionalSystem self-check
Initially, after turning the key in steering lock to
position 2, malfunctions are detected and indicated (the
indicator lamps in the “SOS” button, the Roadside
Assistance button • and Information button ¡
stay on longer than 10 seconds or do not come on). The
message “TELE AID – PLEASE VISIT WORKSHOP”
appears in the MCS display.

Important!
Always make sure that the indicator lamps in the
“SOS” button, the Roadside Assistance button • and
the Information button ¡do not remain illuminated
constantly in red and the message “TELE AID – VISIT
WORKSHOP” is not displayed in the MCS display after
the system self check.
If a malfunction is indicated as outlined above, have the
system checked at the nearest Mercedes-Benz Light
Truck Center as soon as possible.
Emergency calls
An emergency call is initiated automatically: • following an accident in which the Emergency
Tensioning Retractors (ETR’s) or airbags deploy,
• if the antitheft alarm or the tow away alarm stays on
for more than 20 seconds, see pages 35 and 36.
An emergency call can also be initiated manually by
opening the cover next to the inside rear view mirror
labeled “SOS”, then pressing the button (for longer than
2 seconds) located under the cover. See below for
instructions on initiating an emergency call manually. Once the emergency call is in progress, the indicator
lamp in the “SOS” button will begin to f lash. The
message “EMERGENCY CALL – CONNECTING CALL”
appears in the MCS display. When the connection is
established, the message “EMERGENCY CALL – CALL
CONNECTED” appears in the MCS 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.
A voice connection between the Response Center and
the occupants of the vehicle will be established
automatically soon after the emergency call has been
initiated. When a voice connection is established the
audio system mutes and the message “TELE AID – EMERGENCY CALL ACTIVE” appears in the MCS
display. The Response Center will attempt to determine
more precisely the nature of the accident provided they
can speak to an occupant of the vehicle.

The Tele Aid system is available if: • it has been activated and is operational. Activation
requires a subscription for monitoring services and
cellular air time

network and pass the information on to the response
center.
Wa r n i n g !
If the indicator lamp in the “SOS” button is
illuminated continuously and there was no voice
connection to the Response Center established,
then the Tele Aid system could not initiate an
emergency call (e.g. the relevant cellular phone
network is not available). The message
“EMERGENCY CALL – CALL FAILED” appears in
the MCS display for approx. 10 seconds.Should this occur, assistance must be summoned
by oth er means.
