Automatic transmission
Effect
ìPark position
Shift into park positionP only
when vehicle is stopped. The
park position is not intended to
serve as a brake when the vehi-
cle is parked. Rather, the driver
should always set the parking
brake in addition to shifting into
park positionP to secure the
vehicle.
If the vehicle’s electrical system
is malfunctioning, the automatic
transmission could remain
locked in park positionP.
Have the vehicle checked as
soon as possible by an autho-
rized Mercedes-Benz Light
Truck Center.
!SmartKey:
If you turn off the engine using the SmartKey and
remove the SmartKey from the starter switch,
the transmission will shift to park positionP
automatically. Keep in mind that turning off the
engine with the SmartKey alone will not automat-
ically shift the transmission to park positionP.
!KEYLESS-GO*:
If you turn off the engine using the KEYLESS-GO*
start/stop button and open a front door, the
transmission will shift to park positionP
automatically. Keep in mind that turning off the
engine using the KEYLESS-GO* start/stop
button alone will not automatically shift the
transmission to park positionP.
iEven though this is possible, make it a prac-
tice to always shift into park positionP before
turning off the engine and remove the SmartKey
from the starter switch, or when using
KEYLESS-GO*, before turning off the engine with
the start/stop button and opening a front door.
Effect
íReverse gear
Shift into reverse gearR only
when the vehicle is stopped.
ëNeutral
No power is transmitted from the
engine to the drive axle. When
the brakes are released, the
vehicle can be moved freely
(pushed or towed).
To avoid damage to the transmis-
sion, never shift into neutral
positionN while driving.
If the ESP
® is deactivated or
malfunctioning:
Shift into neutral positionN only
if the vehicle is in danger of
skidding, e.g. on icy roads.
êDrive
The transmission shifts
automatically. All forward gears
are available.

positionP alone is not intended to or capa-
ble of preventing your vehicle from moving,
possibly hitting people or objects.
Always set the parking brake in addition to
shifting to positionP (
page 68).
When parked on an incline, turn the front
wheels towards the road curb.

automatic transmission out of park
positionP, which could result in an accident
and/or serious personal injury.
