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. 1-14).
•
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 re-
clined, the risk of sliding under the lap
belt and being injured is increased.

FLEXIBLE SEATING
WARNING
• Never allow anyone to ride in the
cargo area or on the rear seats when
they are in the fold-down position. In
a collision, people riding in these ar-
eas without proper restraints are
more likely to be seriously injured or
killed.
• Do not allow people to ride in any
area of your vehicle that is not
equipped with seats and seat belts.
Be sure everyone in your vehicle is in
a seat and using a seat belt properly.
• Do not allow more than one person
to use the same seat belt.
• Do not fold down the rear seats when
occupants are in the rear seat area or
any luggage is on the rear seats.
– Make sure that the seat path is
clear before moving the seat.
– Be careful not to allow hands or
feet to get caught or pinched in
the seat. •
Head restraints/headrests should be
adjusted properly as they may pro-
vide significant protection against
injury in an accident. Always replace
and adjust them properly if they have
been removed for any reason.
• If the head restraints/headrests are
removed for any reason, they should
be securely stored to prevent them
from causing injury to passengers or
damage to the vehicle in case of sud-
den braking or an accident.
• 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.
• Properly secure all cargo to help pre-
vent it from sliding or shif ting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
Folding the rear bench seat up
(if so equipped)
To fold the rear bench seat up:
1. Lif t up on the lever, located on the side of the seat, while lif ting the front of the seat
cushion up.
LRS3433
Safety-Seats, seat belts and supplemental restraint system1-7

2. Fold the bottom of the seat cushion to-ward the back of the vehicle until it locks
in place. 3. Repeat this process to raise and secure
the seat cushion on the other side of the
vehicle for maximum storage capacity.
To return the rear bench seat to a seating
position, reverse the process. Make sure to
properly push the seat cushion down
into place.
WARNING
• When the vehicle is being used to
carry cargo, properly secure all cargo
to help prevent it from sliding or
shif ting. Do not place cargo higher
than the seatbacks. In a sudden stop
or collision, unsecured cargo could
cause personal injury.
• Do not allow people to ride in any
area of your vehicle that is not
equipped with seats and seat belts.
Be sure everyone in your vehicle is in
a seat and using a seat belt properly.
Never ride in the rear seat unless the
seat bottom cushions are in place
and latched.
• 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.

The illustration shows the seating positions
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.

your shoulder and across your chest.
The front passenger seat and the rear
seating positions’ three-point seat belts
have two modes of operation:
• Emergency Locking Retractor (ELR)
• Automatic Locking Retractor (ALR) The ELR mode allows the seat belt to ex-
tend and retract to allow the driver and
passengers some freedom of movement
in the seat. The ELR locks the seat belt
when the vehicle slows down rapidly or
during certain impacts.
The ALR mode (child restraint mode) locks
the seat belt for child restraint installation.
When the ALR mode is activated, the seat
belt cannot be extended again until the
seat belt tongue is detached from the
buckle and fully retracted. The seat belt re-
turns to the ELR mode af ter the seat belt
fully retracts. For additional information,
see “Child restraints” (P. 1-26).
The ALR mode should be used only for
child restraint installation. During nor-
mal seat belt use by an occupant, the ALR
mode should not be activated. If it is
activated it may cause uncomfortable
seat belt tension. It can also change the
operation of the front passenger air bag.
For additional information, see “Front
passenger air bag and status light”
(P. 1-80).
WARNING
When fastening the seat belts, be cer-
tain that the seatbacks are completely
secured in the latched position. If they
are not completely secured, passen-
gers may be injured in an accident or
sudden stop.

• When the vehicle slows down rapidly
