Adjusting
Adjusting
Seats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.
For more information on seats, see “Seats”
(page 99).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.iThe memory function* (
page 103)
lets you store the setting for power
seats*, steering wheel adjustment
(electrical)*, and exterior rear view mir-
rors.
Warning!
G
Do not adjust the driver 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 44).
Never place hands under the seat or near
moving parts while the 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 op-
erated 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.

For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the head re-
straint supports the back of the head at eye
level. This will reduce the potential for injury
to the head and neck in the event of an ac-
cident 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.

ing. Adjusting the steering wheel while driv-
ing, or driving without the steering wheel
adjustment feature locked could cause the
driver to lose control of the vehicle.

SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the electrical steering wheel
adjustment feature* can be operated when
the driver’s door is open. Therefore, do not

pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.
