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 (
page 78) and tow-away alarm

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!

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
TELE AID - VIS-
IT WORKSHOP
is displayed in the MCS dis-
play after the system self-check, a
malfunction in the system has been detect-
ed.
If a malfunction is indicated as outlined
above, the system may not operate as ex-
pected. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.

The Tele Aid system processes calls using
the following priority.


Automatic emergency – First priority


Manual emergency – Second priority


Roadside assistance – Third priority


Information – Fourth priority
Should a higher priority call be initiated
while you are connected, an upgrade (al-
ternating) tone will be heard and the ap-
propriate indicator lamp will flash. If
certain information such as vehicle identi-
fication number or customer information is
not available, the operator may need to re-
transmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retransmis-
sion is completed. Once a call is conclud-
ed, a beep will be heard and the
appropriate indicator lamp will stop flash-
ing. The MCS system operation will re-
sume.

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 of
this text. (A second person may make the
following training procedures quicker and
easier.)

door opener motor head unit.
Exact location and color of the button
may vary by garage door opener brand.
If there is difficulty locating the trans-
mitting button, reference to garage
door opener operator’s manual.

Press “training” button on the garage

Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures


Remove unnecessary loads


Allow engine to warm up under low
load use


Avoid frequent acceleration and decel-
eration


Have all maintenance work performed
at regular intervals by an authorized
Mercedes-Benz Light Truck Center
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
Drinking and driving
PedalsPower assistance
Warning!
G
Drinking and driving and/or taking drugs
and driving are a very dangerous combina-
tion. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgement.
The possibility of a serious or even fatal ac-
cident is sharply increased when you drink
or take drugs and drive.
Don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking
drugs.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal
movement.Warning!
G
When the engine is not running, there is no
power assistance for the steering system. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to steer the vehicle.

180 OperationDriving instructionsBrakes
To help prevent brake disk corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes.
If your brake system is normally only sub-
jected to moderate loads, you should occa-
sionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads.If the parking brake is released and the
brake warning lamp in the instrument clus-
ter stays on and there is no audible warn-
ing (EBP), the brake fluid level in the
reservoir is too low.
Brake pad wear or a leak in the system may
be the reason for low brake fluid in the res-
ervoir.
Have the brake system inspected at an
authorized Mercedes-Benz Light Truck
Center immediately.
All checks and service work on the brake
system should be carried out by an autho-
rized Mercedes-Benz Light Truck Center.Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking ef-
fect. Maintain a safe distance from vehicles
in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.
!Be very careful not to endanger other
road users when you apply the brakes.
Refer to the description of the Brake
Assist System (BAS) (
page 73).
