(Telematic 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 provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted using the volume control on
the MCS unit.

Emergency calls
An emergency call is initiated automatical-
ly:
following an accident in which the
emergency tensioning detractors
(ETDs) or airbags deploy,
if the anti-theft alarm or the tow-away
alarm stays on for more than
20 seconds. See anti-theft alarm sys-
tem (

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.
Warning!
G
The Tele Aid control unit is located under
the front passenger seat. If there is accumu-
lation of water or other liquid in this area,
the Tele Aid control unit could suffer an
electrical short circuit making the system in-
operative. In this case the indicator lamp in
the SOS button will not illuminate during or
will remain illuminated after the system
self-check. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.
If the indicator lamps in the SOS button, in
the Roadside Assistance button and/or in
the Information button do not come on dur-
ing the system self-check or if any of these
indicators remain illuminated constantly in
red and/or the message

267 Practical hints
Towing the vehicle
Towing the vehicle
Mercedes-Benz recommends that the vehi-
cle be transported with all wheels off the
ground using flatbed or appropriate wheel
lift/dolly equipment. This method is pref-
erable to other types of towing.When circumstances do not permit the
recommended towing methods, the vehi-
cle may be towed with all wheels on the
ground only so far as necessary to have the
vehicle moved to a safe location where the
recommended towing methods can be em-
ployed.
!Use flatbed or wheel lift/dolly equip-
ment, with key in steering lock turned
to position0.
Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
To prevent damage during transport,
do not tie down vehicle by its chassis or
suspension parts. Use the towing eyes.
Switch off the ESP (
page 76),
tow-away alarm (
page 80) and the
automatic central locking (
page 89).
!When towing the vehicle with all wheels
on the ground, the selector lever must
be in position N and the key m us t be in
steering lock position 2.
When towing the vehicle with all wheels
on the ground, the vehicle may be
towed only for distances up to 30 miles
(50 km) and at a speed not to exceed
30 mph (50 km/h).
If the vehicle is towed with the front
axle raised (observe instructions re-
garding flexible drive shaft), the engine
must be shut off (key in steering lock
position1). Otherwise, the 4-ETS may
become engaged which may cause loss
of towing control.
!To be certain to avoid additional dam-
age to the vehicle powertrain, however
you should observe the following:
With damage to the front axle
raise front axle
remove flexible drive shaft be-
tween rear axle and transfer
case
With damage to the rear axle
raise rear axle
tow vehicle with wheel lift or
dolly placed under front wheels
With damage to the transfer case
remove flexible drive shaft to
the drive axles
Always install new self-locking nuts
when reinstalling flexible drive shaft.
