Upgrade Signals
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 COMAND system operation will
resume.
!If the indicator lamps do not start flash-
ing after pressing one of the buttons or
remains illuminated (in red) at any
time, the Tele Aid system has detected
a fault or the service is not currently ac-
tive, and may not initiate a call. Visit
your Mercedes-Benz Light Truck Cen-
ter and have the system checked or
contact the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada) as soon
as possible.
!If the indicator lamp continues to flash
or the system does not reset, contact
the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada), or
Mercedes-Benz Customer Assistance
at 1-800-FOR-MERCedes

tomer Service at 1-800-387-0100 in
Canada.iThe indicator lamp in the respective
button flashes until the call is conclud-
ed. Calls can only be terminated by a
Response Center or Customer Assis-
tance Center representative, except
Roadside Assistance and Information
calls, which can also be terminated by
pressing button

ture, follow these instructions after
completing the “Programming” portion of
this text. (A second person may make the
following training procedures quicker and
easier.)

ter. Canadian programming
During programming, your hand-held
transmitter may automatically stop trans-
mitting.

grated remote control transmitter but-
ton (refer to steps two through four in
the “Programming” portion) while you
press and re-press (“cycle”) your
hand-held transmitter every two sec-
onds until the frequency signal has
been learned.
Upon successful training, the indicator
lamp will flash slowly and then rapidly
after several seconds.

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
Pedals
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.

198 OperationDriving instructionsPower assistanceBrakesTo 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 (EBB), 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 au-
thorized Mercedes-Benz Light Truck Cen-
ter immediately.
All checks and service work on the brake
system should be carried out by an autho-
rized Mercedes-Benz Light Truck Center.
Install only brake pads and brake fluid
recommended by Mercedes-Benz.Warning!
G
When the engine is not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to stop or steer the vehi-
cle.Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components
or salty road conditions, the first braking ac-
tion may be somewhat reduced and in-
creased pedal pressure may be necessary to
obtain expected braking effect. 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).

200 OperationDriving instructionsTiresTread wear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1⁄16
in (1.5 mm), at which point the
tire is considered worn and should be re-
placed.
The tread wear indicator appears as a solid
band across the tread.
Specified tire pressures must be main-
tained. This applies particularly if the tires
are subject to high loads (e.g. high speeds,
heavy loads, high ambient temperatures).
Hydroplaning
Depending on the depth of the water layer
on the road, hydroplaning may occur even
at low speeds and with new tires. Reduce
vehicle speed, avoid track grooves in the
road and apply brakes cautiously in the
rain.
!Set the parking brake whenever park-
ing or leaving the vehicle. In addition,
move selector lever to positionP. In ad-
dition, when parking on hills, always set
the parking brake and turn front wheel
towards the curb.Warning!
G
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
ti o n to a n a r ea wh ic h i s a s a fe dis t an c e f ro m
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have it towed to the nearest
Mercedes-Benz Light Truck Center or tire
dealer for repairs.
Warning!
G
Do not allow your tires to wear down too far.
As tread depth approaches
1⁄16in (1.5 mm),
the adhesion properties on a wet road are
sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
may lose control of the vehicle. Continued
driving with a flat tire or driving at high
speed with a flat tire will cause excessive
heat build-up and possibly a fire.
