contents, especially hot liquids, could spill
during braking, vehicle maneuvers, or an
accident. Liquids spilled on vehicle occu-
pants may cause serious personal injury.
Liquids spilled on vehicle equipment may
cause damage not covered by the
Mercedes-Benz Limited Warranty.
When not in use, keep rear cup holder
closed. An open cup holder may cause injury
to you or others when contacted during
braking, vehicle maneuvers, or in an acci-
dent.

Before driving off, check that the floormats
are securely in place and adjust them if nec-
essary. A loose floormat could slip and
hinder proper functioning of the pedals.
Do not place several floormats on top of
each other as this may impair pedal move-
ment.

To install or remove the floormat more easi-
ly, move the driver’s seat or front passenger seat
as far to the rear as possible (

direction of arrow3.
The heated steering wheel is switched
off. Indicator lamp2 goes out.
For information on the steering wheel, see
“Multifunction steering wheel”
(
page 148).
Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Light Truck Center
for information on the installation of an ap-
proved external antenna. Refer to the radio
transmitter operation instructions regard-
ing use of an external antenna.

i
The steering wheel heating switches off
automatically when you remove the SmartKey
from the starter switch or, on vehicles with
KEYLESS-GO*, when you switch off the ignition
(
page 39) and open the driver’s door.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or serious
personal injury.
Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle. A driver’s
attention to the road must always be
his /her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call.
If you choose to use the telephone
1 while
driving, please use the hands-free device
and only use the telephone when road,
weather and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
cellular telephone while driving a vehicle.
Only operate the COMAND system1 if road,
weather and traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.

Emergency calls
An emergency call is initiated automatical-
ly following an accident in which the emer-
gency tensioning devices (ETDs) or
air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 311) for
instructions on initiating an emergency call
manually.Once the emergency call is in progress, the
indicator lamp on the SOS button will
begin to flash. The message
Connecting call
appears in the multifunc-
tion display. When the connection is estab-
lished, the message
Call connected

appears in the multifunction display. All in-
formation relevant to the emergency, such
as the location of the vehicle (determined
by the GPS satellite location system), vehi-
cle model, identification number and color
are generated.
A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to
determine more precisely the nature of the
accident provided they can speak to an
occupant of the vehicle.
Warning!
G
If the indicator lamps on the SOS button, on
the Roadside Assistance button, and/or on
the Information button remain illuminated
continuously in red and/or the message Tele Aid
– inoperative
is displayed in
the multifunction display after the system
self-check, a malfunction in the system has
been detected.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.

Driving instructions
Driving instructions
Drive sensibly – save fuel
Fuel consumption, to a great extent,
depends on driving habits and operating
conditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures.


Remove unnecessary loads.


Remove carriers* when not in use.


Allow engine to warm up under low
load use.


Avoid frequent acceleration and decel-
eration.


Have all maintenance work performed
at the intervals specified in the
Maintenance Booklet and as required
by the Maintenance System (U.S. vehi-
cles) or FSS PLUS (Canada vehicles).
Contact an authorized Mercedes-Benz
Light Truck Center.Fuel consumption is also increased by
driving in cold weather, in stop-and-go traf-
fic, on short trips and in hilly areas.
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 judgment.
The possibility of a serious or even fatal
accident are greatly increased when you
drink or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Warning!
G
Make sure that absolutely no objects are ob-
structing the pedal’s range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure that the pedals still
have sufficient clearance.
During sudden driving or braking maneu-
vers, the objects could get caught between
the pedals. You could then no longer brake
or accelerate. This could lead to accidents
and injury.

326 OperationDriving instructionsPower assistance
Brakes
Warning!
G
With the engine 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 brake and steer the ve-
hicle.
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.
!
Operational or performance test must only
be conducted on a two-axle dynanometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or
the transfer case which is not covered by the
Mercedes-Benz Limited Warranty.
!
Because the ESP
® operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO* start/stop button in
position0or1) when testing the brakes on a
brake test dynamometer and such testing should
be no longer than 10 seconds.
Active braking action through the ESP
® may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
