57 Getting started
Driving
After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter
(gasoline engine) or the oxidation catalyst
(diesel engine) to reach its operating tem-
perature earlier.For more information, see
“Driving instructions” (
page 339).
!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 56).
iOnce 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 183).
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 gear selector
lever 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.
!Shift the automatic transmission to
positionP orR only when the vehicle is stopped
in order to avoid damaging the transmission.
!Do not run cold engine at high engine
speeds. Running a cold engine at high engine
speeds may shorten the service life of the
engine.
!Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake and
drivetrain wear.

6Rear window wiper indicator
Switch on the ignition (page 39).
Activating intermittent wipe
Turn rear window wiper switch 1 to
position3.
In the lower multifunction display you
will see indicator6, indicating that
the rear window wiper is activated.Deactivating intermittent wipe
Turn rear window wiper switch 1 to
position4 (
page 61).
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
switch 1 in position 2 or 5
(
page 61) 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 362).
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.
iThe rear window wiper engages auto-
matically when the automatic transmission is
shifted to positionR with the windshield wipers
switched on.

190 Controls in detail
Automatic transmission
For information on driving with an
automatic transmission see “Automatic
transmission” (
page 53).
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.

transmission

iDuring 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 pedals’ 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
Catalytic converter (gasoline engine)
Your vehicle is equipped with
monolithic-type catalytic converters, an
important element in conjunction 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 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.
!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,
excessive unburned fuel may reach the catalytic
converter, 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.
Warning!G
As with any vehicle, do not idle, park or
operate this vehicle in areas where combus-
tible 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.

511 Practical hints
Jump starting
Jump starting
If the battery is discharged, the engine can
be started with jumper cables and the bat-
tery of another vehicle. Observe the follow-
ing:
Jump starting should only be performed
using the jump-start contacts in the en-
gine compartment (
page 512).
Jump starting should only be performed
when the engine and catalytic
converter
1 are cold.
Do not start the engine if the battery is
frozen. Let the battery thaw out first.
Only jump start from batteries with the
same voltage rating (12 V). Jump start-
ing with a more powerful battery could
damage the vehicle’s electrical system,
which will not be covered by the
Mercedes-Benz Limited Warranty.
Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
Always make sure the jumper cables
are not on or near pulleys, fans or other
parts that move when the engine is
started or running.
Warning!G
Failure to follow these directions will cause
damage to the electronic components, and
can lead to a battery explosion and severe
injury or death.
Never lean over batteries while connecting
or jump starting, you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water, and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and very explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking, etc.
Attempting to jump start a frozen battery
can result in it exploding, causing personal
injury.
Read all instructions before proceeding.
1Vehicles with gasoline engine only.
!Do not tow-start the vehicle.
!Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick charge unit.
If the engine does not run after several unsuc-
cessful starting attempts, have it checked at the
nearest authorized Mercedes-Benz Light Truck
Center.
Excessive unburned fuel generated by repeated
failed starting attempts may damage the cata-
lytic converter
1.
Make sure the jumper cables do not have loose
or missing insulation.
Make sure the cable clamps do not touch any
other metal part while the other end is still at-
tached to a battery.
