Seat adjustment
Warning!G
All seat, head restraint adjustments, as well
as fastening of seat belts, must be done be-
fore the vehicle is put into motion.
Warning!G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the seat belt would apply force at
the abdomen or neck. That could cause se-
rious or fatal injuries. The seat backrest and
seat belts provide the best restraint when
the wearer is in a nearly upright position and
seat belts are properly positioned on the
body.
Warning!G
Your seat must be adjusted so that you can
correctly fasten your seat belt
(
page 368).
Observe the following points:
Adjust the backrest until your arms are
slightly angled when holding the steer-
ing wheel.
Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far back as possible
with the driver still able to operate the
controls properly.
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.
Never place hands under the seat or
near any moving parts while a seat is be-
ing adjusted.
Failure to do so could result in injury to per-
sons.
Warning!G
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.
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. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.

Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For addi-
tional information, see “Children in the vehi-
cle” (
page 57).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
iIf PRE-SAFE® has been activated, the front
passenger’s seat and/or electrically adjustable
rear seats* will be moved to a more favorable
seat position.
iThe memory function (page 365) lets you
store the settings for the seat positions together
with the settings for the steering wheel and the
exterior rear view mirrors.
!When moving the seats, make sure there are
no items in the footwell or behind the seats; oth-
erwise, you could damage the seats.

Manually adjust the head restraint. Push or pull on the upper edge of the
head restraint cushion to the desired
position.
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.
iAdjust 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.
