Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Unsuper-
vised use of vehicle equipment may cause
an accident and/or serious personal injury.

Adjusting
Adjusting
Seats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.
For more information, see “Seats”
(page 109).Warning!
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 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. Your seat
must be adjusted so that you can correctly
fasten your seat belt (
page 45).
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 from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, 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.
