G
As long as the SmartKey with KEYLESS-GO
is in your vehicle, the vehicle can be started.
Therefore, never leave children unattended
in the vehicle, as they could otherwise acci-
dentally start the engine.
When leaving the vehicle, always take the
SmartKey with KEYLESS-GO with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle.

51 Getting started
Driving

Press KEYLESS-GO start/stop
button1 once.
The engine starts if the SmartKey with
KEYLESS-GO is in the vehicle.
For information on turning off the engine
with KEYLESS-GO, see “Turning off with
KEYLESS-GO*” (
page 63).Starting difficulties
If the engine does not start as described,
carry out the following steps:

If you are starting the engine with the
SmartKey, turn SmartKey in starter
switch to position0 and repeat starting
procedure.

If you are starting the engine with
KEYLESS-GO*: Close any doors that
may be open to allow for better
detection of the SmartKey with
KEYLESS-GO*.
Or:

Remove KEYLESS-GO* start/stop but-
ton from starter switch.

Start the engine with the SmartKey as
radio signals from another source may
be interfering with the SmartKey with
KEYLESS-GO*.

Repeat the starting procedure
(page 49). Remember that extended
starting attempts can drain the battery.

Get a jump start (
page 470).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.

Notify an authorized Mercedes-Benz
Light Truck Center.
iIf you wish to start the engine using the
SmartKey instead of the KEYLESS-GO
feature, remove the KEYLESS-GO*
start/stop button from starter switch
(page 35).

G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could release the
parking brake, which could result in an acci-
dent and/or serious injury.
iWait for the gear selection process to
complete before setting the vehicle in
motion.
iShifting from gear positionP to
positionR, N, orD is only possible with
the brake pedal depressed. Without the
brake pedal depressed, the gear selec-
tor lever can be moved, but the parking
pawl remains engaged, not allowing
shifting to occur.iThe automatic door lock feature can be
deactivated (
page 172).
iYou can open a locked door from the
inside. Open door only when conditions
are safe to do so.

53 Getting started
Driving
After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.For more information, see “Driving instruc-
tions” (
page 299).
For information on off-road driving, see
“Off-road driving” (
page 306).
!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.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.!Shift automatic transmission to
positionPorR 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 acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.

!Vehicles with rain sensor*:
Do not leave windshield wipers in inter-
mittent setting when the vehicle is tak-
en to an automatic car wash or during
windshield cleaning. Wipers will oper-
ate in the presence of water sprayed on
the windshield, and wipers may be
damaged as a result.
Do not operate the wipers when the
windshield is dry. Dust that accumu-
lates on a windshield might scratch the
glass and/or damage the wiper blades
when wiping occurs on a dry wind-
shield. If it is necessary to operate the
wipers in dry weather conditions, al-
ways operate the wipers with wind-
shield washer fluid (
page 56).
iIntermittent wiping is interrupted when
the vehicle is at a standstill and a front
door is opened.
