62 Safety and SecurityOccupant safetySafety guidelines for the seat belt,
emergency tensioning device and
airbagWarning
G
Damaged seat belts or belts that were
highly stressed in an accident must be
replaced and their anchoring points
must also be checked. Use only belts in-
stalled or supplied by an authorized
Mercedes-Benz Light Truck Center.
No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, passenger front airbag cov-
er, or door trim panels, and installation
of additional electrical / electronic
equipment on or near SRS components
and wiring. Keep area between airbags
and occupants free from objects (e.g.
packages, purses, umbrellas, etc.).
Airbags and emergency tensioning de-
vices (ETDs) are designed to function on
a one-time only basis. An airbag or ETD
that was activated must be replaced.
Do not pass belts over sharp edges.
They could tear.
Do not make any modification that could
change the effectiveness of the belts.
Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.
Do n o t h a ng i te ms su ch as c o at ha n ger s
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when curtain airbag is deployed.
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
Airbag system components will be hot
after an airbag has inflated. Do not
touch.
In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air-
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Light Truck Center.
For your protection and the protection
of others, when scrapping the airbag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Light Truck Center.
Given the considerable deployment
speed and the textile structure of the
airbags, there is the possibility of abra-
sions or other injuries resulting from air-
bag deployment.

The Tele Aid system
(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.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.Shortly after the completion of your ac-
quaintance call, you will receive a user ID
and password. By visiting
www.mbusa.com and selecting “Tele Aid”
(USA only), you will have access to account
information, remote door unlock, profile
and more.System self-check
Initially, after switching on ignation, mal-
functions 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 - VISIT WORKSHOP
ap-
pears for approx. 10 seconds in the MCS
display.
iThe SOS button, the Roadside Assis-
tance button• and the Information
button¡ are located in the over-
head control panel.!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 summoned
by other means.

When the indicator lamp6 flashes
rapidly, release both buttons.
Step 6:
Press and hold the just-trained
integrated signal transmitter button
and observe the indicator lamp6.
If the indicator lamp6 stays on con-
stantly, 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.Rolling code programming
To train a garage door opener (or other roll-
ing code devices) with the rolling code fea-
ture, follow these instructions after
completing the “Programming” portion
(steps 1 through 6) of this text. (A second
person may make the following training
procedures quicker and easier.)
Step 8:
Locate “training” button on the garage
door opener motor head unit.
Exact location and color of the button
may vary by garage door opener brand.
Depending on manufacturer, the
“training” button may also be referred
to as “learn” or “smart” button. If there
is difficulty locating the transmitting
button, refer to the garage door opener
operator’s manual.
iThe indicator lamp6 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 lamp6 flashes rapidly
for about two seconds and then turns
to a constant light, continue with pro-
gramming steps 8 through 12 as your
garage door opener may be equipped
with the “rolling code” feature.

Step 9:
Press “training” button on the garage
door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the
following step.
Step 10:
Firmly press, hold for two seconds and
release the programmed integrated
signal transmitter button (3, 4
or5).
Step 11:
Press, hold for two seconds and
release same button a second time to
complete the training process.
Some garage door openers (or other rolling
code equipped devices) may require you to
perform this procedure a third time to
complete the training.Step 12:
Confirm the garage door operation by
pressing the programmed integrated
signal transmitter button (3, 4
or5).
Step 13:
To program the remaining two buttons,
repeat the steps above starting with
step 3.Gate operator / Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the inte-
grated signal transmitter to pick up the sig-
nal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.
If you live in Canada or if you are having dif-
ficulties programming a gate operator (re-
gardless of where you live) by using the
programming procedures, replace step 4
with the following:
