Effect
Park position
ì
Shift the automatic transmission
into park position P only when the
vehicle is stopped. The park
position is not intended to serve
as a brake when the vehicle is
parked. Rather, the driver should
always engage the parking brake
in addition to shifting the
automatic transmission into park
position P to secure the vehicle.
If the vehicle's electrical system is
malfunctioning, the automatic
transmission could remain locked
in park position P.
X
Have the vehicle's electrical
system checked as soon as
possible at an authorized
Mercedes-Benz Center.
Reverse gear
í
Shift the automatic transmission
into reverse gear R only when the
vehicle is stopped.
Effect
Neutral position
ë
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
transmission, never shift the
automatic transmission into
neutral position N while driving.
Exception: If the ESP
deactivated or malfunctioning,
shift the automatic transmission
into neutral position N if the
vehicle is in danger of skidding.
!
Coasting the vehicle, or
driving for any other reason with
the automatic transmission in
neutral position N can result in
transmission damage that is not
covered by the Mercedes-Benz
Limited Warranty.
