out, the trunk lid will open automatical-
ly if a KEYLESS-GO card is recognized
in the area of the rear shelf or inside
the trunk. Warning!
G
Monitor the closing procedure carefully to
ensure that no one is in danger of being in-
jured. To prevent possible personal injury,
always keep hands and fingers away from
the trunk opening when closing the trunk.
Be especially careful when small children
are around. To stop the closing procedure,
press the trunk lid closing switch1 in the
trunk lid, the
Š
button on the SmartKey
or the remote trunk lid switch (on driver's
door control panel).
iIf the trunk lid comes into contact with
an object while closing (e.g. luggage
that has been piled too high), the clos-
ing procedure is stopped and the trunk
re-opens slightly.
The closing procedure can be stopped
at anytime by once again pressing the
trunk lid closing switch in the trunk lid
or the remote control switch in the driv-
er’s door or the

Warning!
G
The seat belts provide protection only with
the backrest locked in place and, therefore,
must be locked in place with the vehicle in
motion. Do not drive the vehicle when the
backrest is not locked in place. If the warn-
ing message
SEAT BACKREST, RIGHT -
LOCK
or
SEAT BACKREST, LEFT - LOCK
is
displayed in the multifunction display, then
the respective backrest is not engaged in its
lock. Carefully slow down, and drive with
caution to an area which is in a safe distance
from the roadway. Always provide sufficient
room behind the backrest and fold the back-
rest all the way back until it locks in place.
Keep the area around head restraints clear
of articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
The warning message is no longer displayed
as soon as the backrest is locked in place. If
both backrests are locked in place and the
warning message is still displayed, have the
system checked at your authorized Mer-
cedes-Benz Center immediately.
When leaving the vehicle, always remove the
electronic key from the starter switch, take
the KEYLESS-GO* card with you, and lock
your vehicle.
The power seats can also be operated with
the driver’s or passenger door open. Do not
leave children unattended in the vehicle or

pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.

moving parts during a seat adjustment pro-
cedure.
