Adjusting
Adjusting
SeatsWarning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
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
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the
abdomen or neck. That could cause serious
or fatal injuries. The seat back and seat belts
provide the best restraint when the wearer
is in a nearly upright position and belts are
properly positioned on the body.
Warning!
G
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 48).
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 to the rear as pos-
sible, consistent with ability to properly
operate controls.
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 an accident
and/or serious personal injury.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle.
Even with the SmartKey or the 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 unattended in the vehicle, or
with access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could re-
sult in an accident and/or serious personal
injury.

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
appropriate infant or toddler restraint, or
booster seat recommended for the size and
weight of the child. For additional informa-
tion, see “Children in the vehicle”
(page 84).
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
The memory function (
page 125) lets you
store the settings for the seat position together
with the settings for the steering wheel and the
exterior rear view mirrors.
!
When moving the seat, make sure there are
no items in the footwell or behind the seats. Oth-
erwise you could damage the seats.
i
Depending on the set height of the head re-
straint, the seat fore and aft position is automat-
ically pre-set.

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
intended to help reduce injuries during an
accident.
i
Adjust the head restraint in such a way that
it is as close to the head as possible.Warning!
G
When folding back the side cushions, never
reach between the side cushion and the
mounting post. You could otherwise be
trapped.
