Warning!
G
The seat belt only offers its intended protec-
tion when the seat backrest is in a nearly
vertical position and the occupant is sitting
upright. Avoid sitting in positions that pre-
vent the seat belt from being properly posi-
tioned against the body (
page 339). You
should therefore adjust the backrest to a po-
sition as upright as possible.
Warning!
G
When adjusting the front passenger seat,
make sure the seat, if occupied, is as far
from the passenger front air bag as possi-
ble.
Otherwise, the passenger could be seriously
or even fatally injured in the event of an ac-
cident or braking maneuver.
Make sure no one is caught or injured while
the seat is being adjusted.
Even with the SmartKey or SmartKey with
KEYLESS-GO* removed from the starter
switch or the SmartKey with KEYLESS-GO*
removed from the vehicle, the power seats
can be operated when the respective door is
open. Therefore, do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment may cause an accident
and/or serious personal injury.!
Do not move the front passenger seat com-
pletely forward if objects are stored in the parcel
net in the front passenger-side footwell. Items in
the net may be damaged.

Luxury active head restraints
(S 600 only) (front seats)
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that it is as close to
the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of
an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.i
Adjust the head restraint in such a way that
it is as close to the head as possible.
i
Depending on the seat’s set fore and aft po-
sition, the head restraint height is automatically
pre-set.
i
The head restraint on the front passenger’s
side is automatically lowered all the way down
while the vehicle is in motion if no one is sitting
on the seat. This helps you to acquire a better
all-round view.
Warning!
G
When folding back the side cushions, never
reach between the side cushion and the
mounting post. You could otherwise be
trapped.

Easy-entry/exit feature
This feature allows for easier entry into and
exit from the vehicle. When entering and
exiting the vehicle, the driver’s seat is in its
maximum rearward position and the steer-
ing wheel is in its uppermost position.
The easy-entry/exit feature can be activat-
ed or deactivated in the “Vehicle” menu of
the COMAND system (
page 224).
Warning!

hicle, or with access to an unlocked vehicle.
Children could open the driver’s door and

feature, which could result in an accident
and/or serious personal injury.


329 Controls in detailSeats
With the easy-entry/exit feature activated,
the steering wheel and driver’s seat will re-
turn to their last set memory position or a
factory-set maximum forward position
when you:

close the driver’s door with the ignition
switched on


insert the SmartKey into the starter
switch or press the KEYLESS-GO*
start/stop button (
page 317) once
with the driver’s door closed. With the easy-entry/exit feature activated
the steering wheel tilts upwards and the
driver’s seat moves a few inches to the
rear when you:


remove the SmartKey from the starter
switch,
or


open the driver’s door with the
SmartKey in starter switch position 0
or 1 or the KEYLESS-GO* start/stop
button (
page 317) in position 1.
!
Do not activate the easy-entry/exit feature
if the seat backrest is in an excessively reclined
position. Doing so could cause damage to front
or rear seats.
First move the seat backrest to an upright posi-
tion.
i
For safety reasons, the driver’s seat will not
return to its last set position with the easy-en-
try/exit feature activated if the system recogniz-
es the last set position as an extreme forward
position. Instead, the driver’s seat will remain at
or move to a factory-set maximum forward posi-
tion. To again fully return the driver’s seat toyour last set position or to memory position, ad-
just the seat to the desired position or press and
hold the respective memory position button
(

positions are stored when


the ignition is switched off


the position is stored in memory

i
If the current position for the steering wheel
is in the uppermost tilt position, the steering
wheel will no longer be able to move upward
when the easy-entry/exit feature is activated.
If the current seat position falls into a factory-set
position range and the system recognizes the
current seat position to be rearward enough for
easy entry and exit, the driver’s seat will not
move to the rear when the easy-entry/ exit fea-
ture is activated.
The adjustment procedure is briefly interrupted
when the engine is started.Warning!
G
Let the system complete the adjustment
procedure before setting the vehicle in mo-
tion. All driver’s seat and steering wheel ad-
justments must be completed before setting
the vehicle in motion. Driving off with the
driver’s seat/steering wheel still adjusting
could cause the driver to lose control of the
vehicle.
