58 Getting startedDrivingDriving off
Depress the brake pedal.
The gear selector lever can now be
used.

Shift automatic transmission toD orR
(page 187).

Release the brake pedal.

Carefully depress the accelerator
pedal.After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter (gaso-
line engine) or the oxidation catalyst (die-
sel engine) to reach its operating
temperature earlier.
i
Wait for the gear selection process to com-
plete before setting the vehicle in motion.
i
Shifting from gear positionP to positionR,
N, orD is only possible with the brake pedal
depressed. Without the brake pedal depressed,
the gear selector lever can be moved, but the
parking pawl remains engaged, not allowing
shifting to occur.
!
If you hear a warning signal and the
message
Release parking brake
appears in
the multifunction display when driving off, you
have forgotten to release the parking brake.
Release the parking brake (
page 57).
i
Once the vehicle is in motion, the automatic
central locking system engages and the locking
knobs drop down.
The automatic door lock feature can be
deactivated (
page 176).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.Warning!
G
It is dangerous to shift the automatic trans-
mission out ofP orN if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.

63 Getting started
Driving
Deactivating intermittent wipe
Turn rear window wiper switch1 to
position4 (
page 62).
Indicator6 for the rear window wiper
is cleared from the lower multifunction
display, indicating that the rear window
wiper is deactivated.
Wiping with windshield washer fluid

Turn and hold rear window wiper
switch1 in position2 or5
(page 62) until the rear window is
clean.
The rear window wiper operates with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield/rear window
washer system and headlamp cleaning
system*” (
page 363).
Problems while driving
The engine runs erratically and misfires

An ignition cable may be damaged
(gasoline engine only).


The engine electronics may not be
operating properly.


Unburned gasoline may have entered
the catalytic converter and damaged it
(gasoline engine only).

Give very little gas.

Have the problem repaired by an
authorized Mercedes-Benz Light Truck
Center as soon as possible.The coolant temperature is above
248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.

Stop the vehicle in a safe location as
soon as possible and turn off the en-
gine. Allow engine and coolant to cool
off.

Check the coolant level and add cool-
ant if necessary (
page 362).

185 Controls in detail
Automatic transmission
Automatic transmission
For more information on driving with an
automatic transmission, see “Automatic
transmission” (
page 54).
Your vehicle’s transmission adapts its gear
shifting process to your individual driving
style by continually adjusting the shift
points up or down. These shift point adjust-
ments are performed based on current
operating and driving conditions.
If the operating conditions change, the
automatic transmission reacts by
adjusting its shift program.
Gear selector lever
The gear selector lever is located on the
right of the steering column.Gearshift pattern for automatic
transmissionPPark position

i
During the brief warm-up, transmission
upshifting is delayed. This allows the catalytic
converter (gasoline engine) or the oxidation
catalyst (diesel engine) to heat up more quickly
to operating temperature.
Warning!
G
Make sure that absolutely no objects are
obstructing 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 maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.

349 Operation
Driving instructions
Telephones and two-way radios
Radio transmitters, such as a portable
telephone or a citizens band unit should
only be used inside the vehicle if they are
connected to an antenna that is installed
on the outside of the vehicle.
Refer to the radio transmitter operation
instructions regarding use of an external
antenna.
Catalytic converter (gasoline engine)
Your Mercedes-Benz is equipped with
monolithic-type catalytic converters, an
important element in conjunction with the
oxygen sensors to achieve substantial con-
trol of the pollutants in the exhaust emis-
sions. Keep your vehicle in proper
operating condition by following our rec-
ommended maintenance instructions as
outlined in your Maintenance Booklet.
Oxidation catalyst (diesel engine)
Your vehicle is equipped with an oxidation
catalyst, an important element in conjunc-
tion with the oxygen sensors to achieve
substantial control of the pollutants in the
exhaust emissions. Keep your vehicle in
proper operating condition by following
our recommended maintenance instruc-
tions as outlined in your Maintenance
Booklet.
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,
possibly resulting in an accident and/or
personal injury.
!
To prevent damage to the catalytic convert-
ers, use only premium unleaded gasoline in this
vehicle.
Any noticeable irregularities in engine operation
should be repaired promptly. Otherwise, exces-
sive unburned fuel may reach the catalytic con-
verter, causing it to overheat and potentially
start a fire.
Warning!
G
As with any vehicle, do not idle, park or op-
erate this vehicle in areas where combusti-
ble materials such as grass, hay or leaves
can come into contact with the hot exhaust
system, as these materials could be ignited
and cause a vehicle fire.
