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 58).
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.
i
If 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.
i
The memory function (
page 392) 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.

If one or more of the lamps on the seat ven-
tilation button are flashing, there is insufficient
voltage available since too many electrical con-
sumers are turned on. The seat ventilation
switches off automatically.
The seat ventilation will switch back on again au-
tomatically as soon as sufficient voltage is avail-
able.
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.

392 Controls in detailMemory functionPrior to operating the vehicle, the driver
should check and adjust the seat height,
seat position fore and aft, and seat back-
rest angle if necessary, to ensure adequate
control, reach, and comfort. The head re-
straint should also be adjusted for proper
height. See also the section on air bags
(page 42) for proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, operation
and comfort. Both the interior and exterior
rear view mirrors should be adjusted for
adequate rear vision.
Fasten seat belts. Infants and small chil-
dren should be seated in a properly se-
cured restraint system that complies with
U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213 and
210.2.With the memory function you can store up
to three different configurations.
Each stored position on the driver’s side
includes the following settings:
Driver’s seat: head restraint height,

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. Therefore, do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child’s un-
supervised access to a vehicle could result
in an accident and/or serious personal
injury.
