38 Getting startedAdjustingSeatsWarning!
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
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 belt would apply force at the ab-
domen or neck. That could cause serious or
fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a nearly upright position and
belts are properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 39).
Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
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 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. Unsupervised use of vehicle equip-
ment may cause 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
appropriate infant, or toddler restraint, or
booster seat recommended for the size and
weight of the child. For additional
information, see “Children in the vehicle”
(page 78).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.

With the engine not running, there is no
power assistance for the brake and the
steering system. In this case, it is important
to keep in mind that a considerably higher
degree of effort is necessary to brake and
steer the vehicle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:
Keep right foot on brake pedal.
Firmly depress parking brake pedal.
Shift the automatic transmission to
positionP.
