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 36 and 37.
An emergency call can also be initiated manually by
opening the cover next to the inside rear view mirror
labeled “SOS”, then briefly pressing the button 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 flash. 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.

Towing a trailer
There are many different laws, including speed limit
restrictions, having to do with trailer towing. Make sure
that your rig will be legal, not only for where you reside,
but also for where you will be driving. A good source for
this information can be the police or local authorities.
Before you start driving with the trailer, check the
trailer hitch, break-away switch, safety chains, electrical
connections, lighting and tires. Also adjust the mirrors
to permit unobstructed view beyond rear of trailer.
If the trailer has electric brakes, start your vehicle and
trailer moving slowly, and then apply only the trailer
brake controller by hand to be sure the brakes are
working properly.
When towing a trailer, check occasionally to be sure that
the load is secure, and that lighting and trailer brakes
(if so equipped) are functioning properly.
Always secure items in the trailer to prevent load shifts
while driving.
Take into consideration that when towing a trailer, the
handling characteristics are different and less stable
from those when operating the vehicle without a trailer.
It is important to avoid sudden maneuvers.The vehicle and trailer combination is heavier, and
therefore is limited in acceleration and climbing ability,
and requires longer stopping distances. It is more prone
to reacting to side wind gusts, and requires more
sensitive steering input.
In order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free from
traffic.
If possible, do not brake abruptly, but rather engage the
brake slightly at first to permit the trailer to activate its
brake. Then increase the braking force.
Caution!
If the trailer should begin to sway, reduce the vehicle’s
speed and use the brake controller by hand to straighten
out the vehicle and trailer. In no case should you
attempt to straighten out the tow vehicle and trailer by
increasing the speed or oversteering and stepping on
the brakes.
If the transmission hunts between gears on inclines,
manually shift to a lower gear (select “4”, “3”, “2”
or “1”). A lower gear and reduction of speed reduces the
chance of engine overloading and / or overheating.
