Switching off the ESP
To improve the vehicle's traction, turn off
the ESP in driving situations where it would
be advantageous to have the drive wheels

deep snow in conjunction with snow
chains
sand or gravelThe switch is located on the center con-
sole.

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
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.
!The automatic seat slide is provided
with a safety feature.
The automatic process is interrupted, if
the backrest of the sliding seat is
pushed against an occupant or object.
The seat will slide forward and stop.
Investigate and correct the cause of in-
terruption.
Now use memory button (
page 105)
or seat adjustment switch (page 35)
to bring seat into desired position.
When folding the backrest forward
from a reclined position, and then fold-
ing it back, the backrest stops in a
more upright position for the safety of
any rear-seat passenger. Adjust the
backrest until your arms are slightly an-
gled when holding the steering
wheel (
page 35).
