other reason with gear selector lever
inN can result in transmission damage
that is not covered by the
Mercedes-Benz Limited Warranty.

selector lever not fully engaged in positionP
is dangerous. Also, positionP alone is not
intended to or capable of preventing your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to positionP (
page 57).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where
combustible 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.

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 move the
