practice 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 the driver’s door.!If you want the gear position to remain
inN (for example when the vehicle is
pulled through a car wash)
do not remove the SmartKey from
the starter switch
or, when using KEYLESS-GO*
do not turn off the engine using the
KEYLESS-GO start/stop button*

vehicle can be moved freely
(pushed or towed).
To avoid damage to the trans-
mission, never shift into neutral

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.
ê

The transmission shifts
automatically. All forward gears
are available.
!Coasting the vehicle, or driving for any
other reason in neutral positionN can
result in transmission damage that is
not covered by the Mercedes-Benz
Limited Warranty.Warning!
G
Getting out of your vehicle without shifting
into park positionP is dangerous. Also, park
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 park positionP (
page 65).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where com-
bustible 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.
