!When moving the seat, make sure there are
no items in the footwell or behind the seats. Oth-
erwise you could damage the seats.
Warning!G
The seat belts provide protection only with
the backrest locked in place. Therefore, the
backrest 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 warning message:
Engage
front-passenger
seat
or
Engage
driver’s
seat
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 dis-
tance from the roadway. Always provide suf-
ficient room behind the backrest and fold
the backrest all the way back until it locks in
place.
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 an authorized
Mercedes-Benz Center immediately.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the 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
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.
Never place hands under seat or near any
moving parts during a seat adjustment pro-
cedure.
