40 SEATS AND RESTRAINTS
Raising the Seatback
{Warning
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.
{Warning
A seat belt that is improperly
routed, not properly attached,
or twisted will not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. After raising the
rear seatback, always check to be
sure that the seat belts are properly
routed and attached, and are not
twisted.To raise a seatback:
1. Lift the seatback up. Make sure the center seat belt and latch do not
get trapped behind the seat. Push
the seatback rearward to lock it in
place.
A red tab near the seatback lever
retracts when the seatback is
locked in place.
2. Push and pull the top of the seatback to be sure it is locked into
position.
3. Reconnect the center seat belt mini-latch to the mini-buckle. Do
not let the belt twist.
4. Pull on the center seat belt to make sure the mini-latch is secure.
5. Repeat the steps to raise the other seatback, if necessary.
When the seat is not in use, it should
be kept in the upright, locked position.
Seat Belts
This section describes how to use seat
belts properly, and some things not
to do.
{Warning
Do not let anyone ride where a seat
belt cannot be worn properly. In a
crash, if you or your passenger(s)
are not wearing seat belts, injuries
can be much worse than if you are
wearing seat belts. You can be
seriously injured or killed by hitting
things inside the vehicle harder or
by being ejected from the vehicle.
In addition, anyone who is not
buckled up can strike other
passengers in the vehicle.
It is extremely dangerous to ride in
a cargo area, inside or outside of a
vehicle. In a collision, passengers
riding in these areas are more likely
to be seriously injured or killed. Do
not allow passengers to ride in any
area of the vehicle that is not
equipped with seats and seat belts.
Always wear a seat belt, and check
that all passenger(s) are restrained
properly too.

This vehicle has indicators as a
reminder to buckle the seat belts. See
Seat Belt Reminders095.
Why Seat Belts Work
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 vehicle
after 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 withseat 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.
Buckle To Drive
If equipped, this feature prevents the
vehicle from shifting out of P (Park)
when the driver seat belt is not
buckled. The Buckle to Drive feature
must be turned ON in the
infotainment system to work. See
Vehicle Personalization 0117 and if
equipped, Teen Driver 0184. If the
engine is running, the driver seat belt
is not buckled, and the brake pedal is
pressed with the vehicle in P (Park), a
message displays in the Driver
Information Center (DIC). Buckle the
driver seat belt to shift out of P (Park).
Shifting from P (Park) will be
prevented once for each ignition cycle.
For some fleet vehicles, the feature is
always ON and it cannot be turned
OFF in the infotainment system.
Shifting from P (Park) will be
prevented each time the above
conditions exist.
On some models, Buckle to Drive may
also prevent shifting out of P (Park) if
a front passenger is unbuckled under
similar conditions. A message displays
in the DIC. Buckle the front passenger
seat belt to shift out of P (Park). This

feature may not allow the vehicle to
shift out of P (Park) if an object, such
as a briefcase, handbag, grocery bag,
laptop, or other electronic device, is
on the front passenger seat. If this
happens, remove the object from the
seat or buckle the seat belt to shift
out of P (Park).
If the driver, or on some vehicles, the
present front passenger remains
unbuckled, the DIC message will turn
off after several seconds and the
vehicle can be shifted out of P (Park).
See“Seat Belts” and“Child Restraints”
in the Index for information about the
importance of proper restraint use.
If the driver seat belt, and in some
vehicles the front passenger seat belt,
is unbuckled when driving, the seat
belt reminder chime and light(s) will
come on. See Seat Belt Reminders 095.
This feature may not function
properly if the airbag readiness light is
on. See Airbag Readiness Light 096.
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 059 or
Infants and Young Children 060.
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.
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 (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, 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.
Always use the correct buckle for your
seating position.
Never route the lap or shoulder belt
over an armrest.

44 SEATS AND RESTRAINTS
{Warning
The seat belt can be pinched if it is
routed under plastic trim on the
seat, such as trim around the rear
seatback folding handle or side
airbag. In a crash, pinched seat
belts might not be able to provide
adequate protection. Never allow
seat belts to be routed under plastic
trim pieces.
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 038 for instructions on
reconnecting the seat belt to the
mini-buckle.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. If the seat has a seat belt guide, the seat belt must be routed through
the guide to properly position the
shoulder belt. If the seat belt is not routed through the guide, slide the
edge of the belt webbing through
the opening on the guide. Be sure
the belt is not twisted.
2. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”in
the Index.
3. 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. See
Child
Restraint Systems 063. If this
occurs, let the belt go back all the
way and start again. If the locking
feature stays engaged after letting
the belt go back to stowed position
on the seat, move the seat rearward
or recline the seat until the
shoulder belt retractor lock
releases.
Engaging the child restraint locking
feature in the front outboard
seating position may affect the
passenger sensing system. See
Passenger Sensing System 053.

If the webbing locks in the latch
plate before it reaches the buckle,
tilt the latch plate flat to unlock.
4. Push the latch plate into the buckleuntil it clicks.
Pull up on the latch plate to make
sure it is secure. If the belt is not
long enough, see Seat Belt Extender
0 46.
Position the release button on the
buckle so that the seat belt could
be quickly unbuckled if necessary.
5. To make the lap part tight, pull up on the shoulder belt.
It may be necessary to pull the
webbing firmly, through the
adjustable stop, or move the
adjustable stop along the webbing toward the outboard floor anchor,
to fully tighten the lap belt across
the lap.
To unlatch the belt, push the button
on the buckle. The belt should return
to its stowed position.
Slide the adjustable stop along the
webbing toward the guide loop when
the seat belt is not in use to prevent
the latch plate from rattling against
the interior trim.
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.
Seat Belt Pretensioners
This vehicle has seat belt
pretensioners for the front outboard
occupants. Although the seat belt
pretensioners cannot be seen, they are
part of the seat belt assembly. They
can help tighten the seat belts during
the early stages of a moderate to
severe frontal, near frontal, or rear
crash if the threshold conditions for
pretensioner activation are met. Seat
belt pretensioners can also help
tighten the seat belts in a side crash
or a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash, the
pretensioners and probably other
parts of the vehicle's seat belt systemwill need to be replaced. See
Replacing
Seat Belt System Parts after a Crash
0 47.
Do not sit on the outboard seat belt
while entering or exiting the vehicle or
at any time while sitting in the seat.
Sitting on the seat belt can damage
the webbing and hardware.
Rear Seat Belt Comfort Guides
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.
Comfort guides are available through
your dealer for the rear outboard
seating positions. Instructions are
included with the guides.
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.

SEATS AND RESTRAINTS 47
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 information on
the proper use and fit of seat belt
extenders see the instruction sheet
that comes with the extender.
Safety System Check
Periodically check the seat belt
reminder, seat belts, buckles, latch
plates, retractors, shoulder belt height
adjusters (if equipped), and seat belt
anchorages to make sure they are all
in working order. Look for any other
loose or damaged seat belt system
parts that might keep a seat belt
system from performing properly. See
your dealer to have it repaired. Torn,
frayed, or twisted seat belts may not
protect you in a crash. Torn or frayed
seat belts can rip apart under impact
forces. If a belt is torn or frayed, haveit replaced immediately. If a belt is
twisted, it may be possible to untwist
by reversing the latch plate on the
webbing. If the twist cannot be
corrected, ask your dealer to fix it.
Make sure the seat belt reminder light
is working. See
Seat Belt Reminders
0 95.
Keep seat belts clean and dry. See Seat
Belt Care 047.
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly cared for
and maintained.
Seat belt hardware should be kept dry
and free of dust or debris. As
necessary, exterior hard surfaces and
seat belt webbing may be lightly
cleaned with mild soap and water.
Ensure there is not excessive dust or
debris in the mechanism. If dust or
debris exists in the system please see
the dealer. Parts may need to be
replaced to ensure proper
functionality of the system.
{Warning
Do not bleach or dye seat belt
webbing. It may severely weaken
the webbing. In a crash, they might
not be able to provide adequate
protection. Clean and rinse seat belt
webbing only with mild soap and
lukewarm water. Allow the webbing
to dry.
Replacing Seat Belt
System Parts after a Crash
{Warning
A crash can damage the seat belt
system in the vehicle. A damaged
seat belt system may not properly
protect the person using it,
resulting in serious injury or even
death in a crash. To help make sure
the seat belt systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.

48 SEATS AND RESTRAINTS
After a minor crash, replacement of
seat belts may not be necessary. But
the seat belt assemblies that were
used during any crash may have been
stressed or damaged. See your dealer
to have the seat belt assemblies
inspected or replaced.
New parts and repairs may be
necessary even if the seat belt system
was not being used at the time of the
crash.
Have the seat belt pretensioners
checked if the vehicle has been in a
crash, or if the airbag readiness light
stays on after you start the vehicle or
while you are driving. SeeAirbag
Readiness Light 096.
Airbag System
The vehicle has the following airbags:
.A frontal airbag for the driver
.A frontal airbag for the front
outboard passenger
.A knee airbag for the driver.
.A knee airbag for the front outboard
passenger.
.A seat-mounted side impact airbag
for the driver
.A seat-mounted side impact airbag
for the front outboard passenger
.A roof-rail airbag for the driver and
the passenger seated directly behind
the driver
.A roof-rail airbag for the front
outboard passenger and the
passenger seated directly behind the
front outboard passenger
All vehicle airbags have the word
AIRBAG on the trim or on a label near
the deployment opening.
For frontal airbags, the word AIRBAG
is on the center of the steering wheel
for the driver and on the instrument
panel for the front outboard
passenger.
For knee airbags, the word AIRBAG is
on the lower part of the instrument
panel.
For seat-mounted side impact airbags,
the word AIRBAG is on the side of the
seatback or side of the seat closest to
the door.
For roof-rail airbags, the word AIRBAG
is on the ceiling or trim. Airbags are designed to supplement
the protection provided by seat belts.
Even though today's airbags are also
designed to help reduce the risk of
injury from the force of an inflating
bag, all airbags must inflate very
quickly to do their job.
Here are the most important things to
know about the airbag system:
{Warning
You can be severely injured or
killed in a crash if you are not
wearing your seat belt, even with
airbags. Airbags are designed to
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. See
When Should an
Airbag Inflate? 051.
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 (Continued)

Warning (Continued)
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 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.(Continued)
Warning (Continued)
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 059 or
Infants and Young Children 060.
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 096.
Where Are the Airbags?
The driver frontal airbag is in the
center of the steering wheel.
The front outboard passenger frontal
airbag is in the passenger side
instrument panel.
