WARNING
• Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and re-
ceive neck or other serious injuries.
You could also slide under the lap belt
and receive serious internal injuries. •
For the most effective protection
when the vehicle is in motion, the
seat should be upright. Always sit
well back and upright in the seat with
both feet on the floor and adjust the
seat properly. For additional infor-
mation, see “Precautions on seat belt
usage” (P. 1-12).
• Af ter adjustment, gently rock in the
seat to make sure it is securely
locked. •
Do not leave children unattended in-
side the vehicle. They could unknow-
ingly activate switches or controls or
make the vehicle move. Unattended
children could become involved in
serious accidents.
• To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
• Do not adjust the driver’s seat while
driving so full attention may be given
to vehicle operation. The seat may
move suddenly and could cause loss
of control of the vehicle.
• The seatback should not be reclined
any more than needed for comfort.
Seat belts are most effective when
the passenger sits well back and
straight up in the seat. If the seatback
is reclined, the risk of sliding under
the lap belt and being injured is
increased.

CAUTION
When adjusting the seat positions, be
sure not to contact any moving parts to
avoid possible injuries and/or damage.
FRONT MANUAL SEAT
ADJUSTMENT (if so equipped)
Your vehicle seats can be adjusted manu-
ally. For additional information about ad-
justing the seats, refer to the steps outlined
in this section.
WARNING
Before driving the vehicle, return the
seatback to an upright seating position
af ter manually releasing it. Also, make
sure the seat is locked in place. Failure
to do so may cause the seat to move in
a collision or sudden stop. This may re-
sult in damage to the seat or personal
injury.
Forward and backward
Pull the center of the bar up and hold it
while you slide the seat forward or back-
ward to the desired position. Release the
bar to lock the seat in position.
Reclining
To recline the seatback, pull the lever up
and lean back. To bring the seatback for-
ward, pull the lever up and lean your body
forward. Release the lever to lock the seat-
back in position.
The reclining feature allows adjustment of
the seatback for occupants of different
sizes for added comfort and to help obtain
proper seat belt fit. For additional informa-
tion, see “Precautions on seat belt usage”
(P. 1-12). Also, the seatback can be reclined
to allow occupants to rest when the vehicle
is stopped and the shif t lever is in the P
(Park) position.

FOLDING REAR SEATInterior trunk access
The trunk can be accessed from the driver
side and passenger side of the rear seat for
loading and unloading, as shown.
1. Move the front passenger seat to themost forward position. 2. Open the access cover on the rear par-
cel shelf.
3. Insert a key or another suitable tool (such as a pen or a screw driver) into the
slot, then slide the recessed lever in the
direction of the arrow
O1.
4. Fold down the passenger's side seat- back
O2.
NOTE:
To access the trunk in case of a dead
battery, use a key or another suitable
tool (such as a pen or screw driver), to
slide recessed lever in the direction of
the arrow.
WARNING
• Never allow anyone to ride in the
cargo area or on the rear seat when it
is in the fold-down position. Use of

•Properly secure all cargo with ropes
or straps to help prevent it from slid-
ing or shif ting. Do not place cargo
higher than the seatbacks. In a sud-
den stop or collision, unsecured
cargo could cause personal injury.
• When returning the seatbacks to the
upright position, be certain they are
completely secured in the latched
position. If they are not completely
secured, passengers may be injured
in an accident or sudden stop.
• Closely supervise children when they
are around cars to prevent them
from playing and becoming locked in
the trunk where they could be seri-
ously injured. Keep the car locked,
with the rear seatback and trunk lid
securely latched when not in use, and
prevent children's access to car keys. To fold down either side of the rear seat,
open the trunk and pull on the knob on that
side
OA.

WARNING
Head restraints/headrests supplement
the other vehicle safety systems. They
may provide additional protection
against injury in certain rear end colli-
sions. Adjustable head restraints/
headrests must be adjusted properly,
as specified in this section. Check the
adjustment af ter someone else uses
the seat. Do not attach anything to the
head restraint/headrest stalks or re-
move the head restraint/headrest. Do
not use the seat if the head restraint/
headrest has been removed. If the head
restraint/headrest was removed, rein-
stall and properly adjust the head
restraint/headrest before an occupant
uses the seating position. Failure to fol-
low these instructions can reduce the
effectiveness of the head restraints/
headrests. This may increase the risk of
serious injury or death in a collision. The illustration shows the seating posi-
tions equipped with head
restraints/headrests.

Indicates the seating position is
equipped with a head restraint.
 Indicates the seating position is
equipped with a headrest.
+ Indicates the seating position is not
equipped with a head restraint or headrest
(if applicable).
• Your vehicle is equipped with a head restraint/headrest that may be inte-
grated, adjustable or non-adjustable. • Adjustable head restraints/headrests
have multiple notches along the stalk(s)
to lock them in a desired adjustment
position.
• The non-adjustable head restraints/ headrests have a single locking notch to
secure them to the seat frame.
• Proper Adjustment: – For the adjustable type, align the headrestraint/headrest so the center of
your ear is approximately level with the
center of the head restraint/headrest.
– If your ear position is still higher than the recommended alignment, place
the head restraint/headrest at the
highest position.
• If the head restraint/headrest has been removed, ensure that it is reinstalled and
locked in place before riding in that des-
ignated seating position.
