The Tele Aid system
(Tele

larm I
dentification on
D
emand)
The Tele Aid system consists of three
types of response:
automatic and manual emergency
roadside assistance
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 when using the volume control
on the Modular COMAND System or on the
multifunction steering wheel. To raise, turn
the rotary volume control on Modular
COMAND System clockwise or press
buttonæ on the multifunction steering
wheel. To lower, turn the rotary volume
control on Modular COMAND System con-trol counterclockwise or press
buttonç on the multifunction steering
wheel.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.iThe SOS button is located in the over-
head control panel.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest
cover.!The Tele Aid system utilizes the cellular
network for communication and the
GPS (G
lobal P
ositioning S
ystem) satel-
lites for vehicle location. If either of
these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.
iWhen a Tele Aid call has been initiated,
the Modular 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 navi-
gation* system (if engaged) will contin-
ue to run. The display in the instrument
cluster is available for use, and spoken
commands are only available by press-
ing the RPT button on the Modular
COMAND System. A pop-up window
will appear in the Modular COMAND
System display to indicate that a Tele
Aid call is in progress. After the TeleAid
call has ended, the optional cellular
phone inserted in the cradle switches
on again. A PIN entry might be neces-
sary.

Hold the end of the hand-held remote
control transmitter6 of the device
you wish to train approximately 2 to
5 in (5 to12 cm) away from the surface
of the integrated remote control
located on the left side of the interior
rear view mirror, keeping the indicator
lamp4 in view.
Step 4:
Using both hands, simultaneously
press the hand-held transmitter
button5 and the desired integrated
signal transmitter button (1, 2
or3). Do not release the buttons until
completing step 5.
The indicator lamp4 on the
integrated remote control will flash,
first slowly and then rapidly.Step 5:
When the indicator lamp4 flashes
rapidly, release both buttons.
Step 6:
Press and hold the just-trained
integrated signal transmitter button
and observe the indicator lamp4.
If the indicator lamp4 stays on
constantly, programming is complete
and your device should activate when
the integrated signal transmitter
button is pressed and released.Step 7:
To program the remaining two buttons,
repeat the steps above starting with
step 3.
iThe indicator lamp4 flashes the first
time the signal transmitter button is
programmed. If this button has already
been programmed, the indicator lamp
will only start flashing after
20 seconds.
iIf the indicator lamp4 flashes rapidly
for about two seconds and then turns
to a constant light, continue with
programming steps 8 through 12 as
your garage door opener may be
equipped with the “rolling code”
feature.

316 OperationDriving instructionsAttaching a trailer
Observe maximum permitted trailer
dimensions (width and length).
Most states and all Canadian provinces
require
safety chains between your tow vehicle
and the trailer.
The chains should be criss-crossed
under the trailer tongue. They must be
attached to the hitch receiver, and not
to the vehicle’s bumper or axle.
Make sure to leave enough slack in the
chains to permit turning corners.
a separate brake system at various
trailer weights.
a break-away switch on trailers with a
separate brake system.
The switch activates the trailer brakes
in the possible event that the trailer
might separate from the tow vehicle.
Start the engine (
page 34).
Make sure the automatic transmission
is set toP.
Set the parking brake for the vehicle
(page 52).
Vehicles with ADS*: Set the vehicle
level to Highway (
page 250).
Vehicle with ADS*: Set the ADS* to
AUTO or COMFORT (
page 249).
Stop the engine (
page 34).
Attach the trailer.
!Do not connect a trailer brake system
(if trailer is so equipped) directly to the
vehicle’s hydraulic brake system, as
your vehicle is equipped with antilock
brakes. If you do, neither the vehicle’s
brakes nor the trailer’s brakes will func-
tion properly.iThe provided vehicle electrical wiring
harness for trailer towing has a brake
signal wire (color orange) for hook-up
to a brake controller.
You should consider using a trailer
sway control system. For further infor-
mation see an authorized
Mercedes-Benz Light Truck Center.
Warning!
G
Vehicles with ADS*:
Do not lock or unlock any doors or the tail-
gate while attaching or uncoupling the trail-
er. Do not open or close any doors or the
tailgate while attaching or uncoupling the
trailer. Make sure no one operates the ADS*
switch (
page 249) or the vehicle level
control* switch (
page 252) while a trailer
is being attached or uncoupled. The vehicle
level could change, and you could injure
yourself and/or others.
