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 entered

Q: If my vehicle has airbags, whyshould 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
This section is only for people of
adult size.
There are special things to know
about seat belts and children, and
there are different rules for smaller
children and infants. If a child will be
riding in the vehicle, see Older
Children 088 orInfants and Young
Children 090. Follow those rules for
everyone's protection. 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.
There are important things to know
about wearing a seat belt properly.
.
Sit up straight and always keep
your feet on the floor in front
of you.
. 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, this applies force to the strong
pelvic bones and you would be
less likely to slide under the lap
belt. If you slid under it, the belt
would apply force on your
abdomen. This could cause
serious or even fatal injuries.
. Wear the shoulder belt over the
shoulder and across the chest.
These parts of the body are best
able to take belt restraining
forces. The shoulder belt locks if
there is a sudden stop or crash.
{Warning
You can be seriously injured,
or even killed, by not wearing
your seat belt properly.
. Never allow the lap or
shoulder belt to become
loose or twisted.
. Never wear the shoulder
belt under both arms or
behind your back.
. Never route the lap or
shoulder belt over an
armrest.

Seats and Restraints 71
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
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. See
Passenger
Sensing System 082.
If the webbing locks in the latch
plate before it reaches the
buckle, tilt the latch plate flat to
unlock.

Rear Seat Belt Comfort Guides
{Warning
A seat belt that is not properly
worn may not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. The shoulder
belt should go over the shoulder
and across the chest. These parts
of the body are best able to take
belt restraining forces.
Rear seat belt comfort guides may
provide added seat belt comfort for
older children who have outgrown
booster seats and for some adults.
When installed on a shoulder belt,
the comfort guide positions the
shoulder belt away from the neck
and head.
This vehicle will have rear seat belt
comfort guides in the rear outboard
seating positions. To install:
1. Remove the guide from its
storage pocket on the side of
the seatback.
2. Place the guide over the belt,and insert the two edges of the
belt into the slots of the guide.

3. Be sure that the belt is nottwisted and it lies flat. The
elastic cord must be behind the
belt with the plastic guide on
the front.
4. Buckle, position, and release
the seat belt as described
previously in this section. Make
sure the shoulder belt crosses
the shoulder. The belt should
be close to, but not contacting,
the neck.
To remove and store the comfort
guide, squeeze the belt edges
together so that the seat belt can be removed from the guide. Slide the
guide back into its storage pocket
on the side of the seatback.
Seat Belt Use During
Pregnancy
Seat belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear seat belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.
The best way to protect the fetus is
to protect the mother. When a seat
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making seat
belts effective is wearing them
properly.
Seat Belt Extender
If the vehicle's seat belt will fasten
around you, you should use it.
But if a seat belt is not long enough,
your dealer will order you an
extender. When you go in to order it,
take the heaviest coat you will wear,
so the extender will be long enough
for you. To help avoid personal
injury, do not let someone else use
it, and use it only for the seat it is
made to fit. The extender has been
designed for adults. Never use it for
securing child restraints. For more

Warning (Continued)
work with seat belts, not replace
them. Also, airbags are not
designed to inflate in every crash.
In some crashes seat belts are
the only restraint. SeeWhen
Should an Airbag Inflate? 079.
Wearing your seat belt during a
crash helps reduce your chance
of hitting things inside the vehicle
or being ejected from it. Airbags
are “supplemental restraints” to
the seat belts. Everyone in the
vehicle should wear a seat belt
properly, whether or not there is
an airbag for that person.
{Warning
Because airbags inflate with great
force and faster than the blink of
an eye, anyone who is up
against, or very close to, any
airbag when it inflates can be
(Continued)
Warning (Continued)
seriously injured or killed. Do not
sit unnecessarily close to any
airbag, as you would be if sitting
on the edge of the seat or leaning
forward. Seat belts help keep you
in position before and during a
crash. Always wear a seat belt,
even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle. The seat belts and
the front outboard passenger
airbags are most effective when
you are sitting well back and
upright in the seat with both feet
on the floor.
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
{Warning
Children who are up against,
or very close to, any airbag when
it inflates can be seriously injured
or killed. Always secure children
properly in the vehicle. To read
how, seeOlder Children 088 or
Infants and Young Children 090.
There is an airbag readiness light
on the instrument cluster, which
shows the airbag symbol.
The system checks the airbag
electrical system for malfunctions.
The light tells you if there is an
electrical problem. See Airbag
Readiness Light 0126.
