Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust the 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 po-
tential 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.

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 268).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 372) once
with the driver’s door closed

trapped or injured by the moving steering
wheel and driver’s seat when the easy-en-
try/exit feature is activated.
To stop seat/steering wheel movement, do
one of the following:
Press seat adjustment switch
(page 374).
Move steering wheel adjustment stalk
(page 386).
Press one of the memory position but-
tons or the memory buttonM

Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Children could open the driver’s door and
unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.

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 to

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.
