For frontal airbags, the word
AIRBAG will appear on the middle
part of the steering wheel for the
driver and on the instrument panel
for the right front passenger.
With seat‐mounted side impact
airbags, the word AIRBAG will
appear on the side of the seatback
closest to the door.
With roof-rail airbags, the word
AIRBAG will appear along the
headliner or trim.
Airbags are designed to supplement
the protection provided by safety
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 safety belt
—even if
you have airbags. Airbags are
designed to work with safety
belts, but do not replace them.
Also, airbags are not designed to
deploy in every crash. In some
crashes safety belts are your only
restraint. See When Should an
Airbag Inflate? on page 3‑33.
Wearing your safety 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 safety belts. Everyone in your
vehicle should wear a safety belt
properly —whether or not there is
an airbag for that person.
{WARNING
Airbags inflate with great force,
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 the airbag, as you would
be if you were sitting on the edge
of the seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear a safety belt,
even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
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.

The roof-rail airbags for the driver,
right front passenger, and second
row outboard passengers are in the
ceiling above the side windows.
{WARNING
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
that person causing severe injury
or even death. The path of an
inflating airbag must be kept
clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering. (Continued)
WARNING (Continued)
Do not use seat accessories
that block the inflation path of a
seat-mounted side impact airbag.
Never secure anything to the
roof of a vehicle with roof-rail
airbags by routing a rope or tie
down through any door or window
opening. If you do, the path of an
inflating roof-rail airbag will be
blocked.

What Makes an Airbag
Inflate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inflator. Gas from the inflator fills the
airbag causing the bag to break out
of the cover and deploy. The inflator,
the airbag, and related hardware are
all part of the airbag module.
Frontal airbag modules are located
inside the steering wheel and
instrument panel. For vehicles with
seat‐mounted side impact airbags,
there are airbags modules in the
side of the front seatbacks closest
to the door. For vehicles with
roof-rail airbags, there are airbag
modules in the ceiling of the vehicle,
near the side windows that have
occupant seating positions.
How Does an Airbag
Restrain?
In moderate to severe frontal or
near frontal collisions, even belted
occupants can contact the steering
wheel or the instrument panel. In
moderate to severe side collisions,
even belted occupants can contact
the inside of the vehicle.
Airbags supplement the protection
provided by safety belts. Frontal
airbags distribute the force of the
impact more evenly over the
occupant's upper body, stopping
the occupant more gradually.
Seat‐mounted side impact and
roof-rail airbags distribute the force
of the impact more evenly over the
occupant's upper body.Rollover capable roof-rail airbags
are designed to help contain the
head and chest of occupants in the
outboard seating positions in the
first and second rows. The rollover
capable roof-rail airbags are
designed to help reduce the risk of
full or partial ejection in rollover
events, although no system can
prevent all such ejections.
But airbags would not help in many
types of collisions, primarily
because the occupant's motion is
not toward those airbags. See
When
Should an Airbag Inflate? on
page 3‑33 for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.

What Will You See After
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at least
partially inflated for some time after
they deploy. Some components of
the airbag module may be hot for
several minutes. For location of the
airbag modules, seeWhat Makes
an Airbag Inflate? on page 3‑35.
The parts of the airbag that come
into contact with you may be warm,
but not too hot to touch. There may
be some smoke and dust coming
from the vents in the deflated
airbags. Airbag inflation does not
prevent the driver from seeing out of
the windshield or being able to steer
the vehicle, nor does it prevent
people from leaving the vehicle.
{WARNING
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention. The vehicle may have a feature
that may automatically unlock
the doors, turn on the interior
lamps and hazard warning flashers,
and shut off the fuel system after
the airbags inflate. You can lock the
doors, turn off the interior lamps and
hazard warning flashers by using
the controls for those features.

Child Restraint Systems
(A) Rear‐Facing Infant Seat
A rear-facing infant seat (A)
provides restraint with the seating
surface against the back of the
infant.
The harness system holds the infant
in place and, in a crash, acts to
keep the infant positioned in the
restraint.
(B) Forward-Facing Child Seat
A forward-facing child seat (B)
provides restraint for the child's
body with the harness.(C) Booster Seats
A booster seat (C) is a child restraint
designed to improve the fit of the
vehicle's safety belt system.
A booster seat can also help a child
to see out the window.

The top drain grates are located
near the rear window on both sides
of the vehicle. Clean the grates and
drains if there is a blockage.
To remove each drain grate, do
the following:
1. Remove the cargo panels.
See Cargo Cover Panels on
page 4‑6 for more information.
2. Grasp the edges of the grate
and pull it out from the vehicle.
Flush the drain with clean water.To replace the drain grate:
1. Line up the clips on the vehiclewith the slots in the grate and
firmly push the grate down.
2. Do not force the grate. If it does not clip into place, realign the
clips with the holes and try
again.

Do not exceed the maximum vehicle
capacity when loading the vehicle.
For more information on vehicle
capacity and loading, seeVehicle
Load Limits on page 9‑24.
.If small heavy objects are
placed on the roof, cut a piece of
3/8 inch plywood to fit inside the
crossrails and siderails to spread
the load. Tie the plywood to the
siderail supports.
.Tie the load and secure it
to the crossrails or the siderail
supports. Use the crossrails only
to keep the load from sliding.
To move a crossrail, lift the
release lever up, on both sides
of the rail. Then slide the
crossrail to the desired position
balancing the force side to side.
Press the release lever down on
both sides of the rail, down to
tighten it. Try to slide the
crossrail back and forth slightly
to make sure it is tight.
.To carry long items, move the
crossrails as far apart as
possible. Tie the load to the
crossrails and the siderails or
siderail supports. Also tie the
load to the bumpers, but do not
tie the load so tightly that the
crossrails or siderails are
damaged.
.After moving a crossrail, be
sure it is securely locked into
the siderail.
A Center High-Mounted Stoplamp
(CHMSL) is located above the rear
window glass.
Make sure items loaded on the roof
of the vehicle do not block or
damage the CHMSL.
