Rear Seats
Rear Seat Reminder
If equipped, the message REAR
SEAT REMINDER LOOK IN REAR
SEAT displays under certain
conditions indicating there may be
an item or passenger in the rear
seat. Check before exiting the
vehicle.
This feature will activate when a
second row door is opened while
the vehicle is on or up to 10 minutes
before the vehicle is turned on.
There will be an alert when the
vehicle is turned off. The alert does
not directly detect objects in the rear
seat; instead, under certain
conditions, it detects when a rear
door is opened and closed,
indicating that there may be
something in the rear seat.
The feature is active only once each
time the vehicle is turned on and off,
and will require reactivation by
opening and closing the second row
doors. There may be an alert even
when there is nothing in the rear
seat; for example, if a child enteredthe vehicle through the rear door
and left the vehicle without the
vehicle being shut off.
The feature can be turned on or off.
See
Vehicle Personalization 0138.
Folding Seatbacks
Either side of the rear seatback can
be folded for more cargo space.
Caution
Folding a rear seat with the seat
belts still fastened may cause
damage to the seat or the seat
belts. Always unbuckle the seat
belts and return them to their
normal stowed position before
folding a rear seat.
To fold the rear seatbacks: 1. Lower the rear head restraints. See Head Restraints 053.2. Disconnect the rear seat belt
mini-latch, using a key in the
slot on the mini-buckle.
3. Let the belt retract.

64 Seats and Restraints
When riding in a vehicle, you travel
as fast as the vehicle does. If the
vehicle stops suddenly, you keep
going until something stops you.
It could be the windshield, the
instrument panel, or the seat belts!
When you wear a seat belt, you and
the vehicle slow down together.
There is more time to stop because
you stop over a longer distance and,
when worn properly, your strongest
bones take the forces from the seat
belts. That is why wearing seat belts
makes such good sense.
Questions and Answers About
Seat Belts
Q: Will I be trapped in the vehicleafter a crash if I am wearing a
seat belt?
A: You could be—whether you are
wearing a seat belt or not. Your
chance of being conscious
during and after a crash, so you
can unbuckle and get out, is
much greater if you are belted. Q: If my vehicle has airbags, why
should I have to wear seat
belts?
A: Airbags are supplemental
systems only. They work with
seat belts —not instead of them.
Whether or not an airbag is
provided, all occupants still have
to buckle up to get the most
protection.
Also, in nearly all states and in
all Canadian provinces, the law
requires wearing seat belts.
How to Wear Seat Belts
Properly
Follow these rules for everyone's
protection.
There are additional things to know
about seat belts and children,
including smaller children and
infants. If a child will be riding in the
vehicle, see Older Children 083 or
Infants and Young Children 085.
Review and follow the rules for
children in addition to the following
rules. It is very important for all occupants
to buckle up. Statistics show that
unbelted people are hurt more often
in crashes than those who are
wearing seat belts.

about wearing a seat belt properly.
.
Sit up straight and always keep
your feet on the floor in front of
you (if possible).
. Always use the correct buckle
for your seating position.
. Wear the lap part of the belt low
and snug on the hips, just
touching the thighs. In a crash,

66 Seats and Restraints
Always use the correct buckle for
your seating position.
Never route the lap or shoulder belt
over an armrest.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
If you are using a rear seating
position with a detachable seat belt
and the seat belt is not attached,
seeRear Seats 061 for instructions
on reconnecting the seat belt to the
mini-buckle.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see
“Seats” in the Index.
2. Pick up the latch plate and pull
the belt across you. Do not let
it get twisted.
The lap-shoulder belt may lock
if you pull the belt across you
very quickly. If this happens, let
the belt go back slightly to
unlock it. Then pull the belt
across you more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be
engaged. If this happens, let
the belt go back all the way
and start again.

Engaging the child restraint
locking feature in the front
outboard seating position may
affect the passenger sensing
system. SeePassenger
Sensing System 077.
3. Push the latch plate into the
buckle until it clicks.
If the latch plate will not go fully
into the buckle, check if the
correct buckle is being used.
Pull up on the latch plate to
make sure it is secure. If the
belt is not long enough, see
Seat Belt Extender 069. Position the release button on
the buckle so that the seat belt
could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height Adjuster”
later in this section for
instructions on use and
important safety information.
5. To make the lap part tight, pull
up on the shoulder belt.
To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position.
Always stow the seat belt slowly.
If the seat belt webbing returns
quickly to the stowed position, the
retractor may lock and cannot be
pulled out. If this happens, pull the
seat belt straight out firmly to unlock
the webbing, and then release it.
If the webbing is still locked in the
retractor, see your dealer.
Before a door is closed, be sure the
seat belt is out of the way. If a door
is slammed against a seat belt,
damage can occur to both the seat
belt and the vehicle.
