Adjusting
Adjusting
Seats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.
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 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 seat belt would apply force at
the abdomen or neck. That could cause se-
rious or fatal injuries. The seat backrest and
seat belts provide the best restraint when
the wearer is in a position that is as upright
as possible and seat belts are properly posi-
tioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 48).
Observe the following points:
Adjust the seat backrest until your arms
are slightly angled when holding the
steering wheel.
Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely.
The position should be as far back as
possible with the driver still able to
operate the controls properly.
Adjust 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
being adjusted.
Failure to do so could result in result in an
accident and/or serious personal injury.

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. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury.
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate 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 79).
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.
!When moving the seats, make sure there are
no items in the footwell or behind the seats;
otherwise you could damage the seats.

Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the head
restraint 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 accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are in-
tended to help reduce injuries during an
accident.
iAdjust the head restraint in such a way that
it is as close to the head as possible.

ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes.

forcibly pushed forward (hit from the rear) or
rearward (hit from the front), reposition it by
applying firm pressure until it snaps into place.
The exterior rear view mirror housing is now
properly positioned and you can adjust the
mirror in the usual manner.
