{WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inflates. This is because the
back of the rear-facing child restraint would be
very close to the inflating airbag. A child in a
forward-facing child restraint can be seriously
injured or killed if the right front passenger airbag
inflates and the passenger seat is in a forward
position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag, no
system is fail-safe. No one can guarantee that an
airbag will not deploy under some unusual
circumstance, even though it is turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. If you secure a
forward-facing child restraint in the right front seat,
always move the front passenger seat as far back
as it will go. It is better to secure the child restraint
in a rear seat.
SeePassenger Sensing System
on page 2‑67
for additional information. If the child restraint has the LATCH system, see
Lower
Anchors and Tethers for Children (LATCH)
on
page 2‑43for how and where to install the child
restraint using LATCH. If a child restraint is secured
using a safety belt and it uses a top tether, see Lower
Anchors and Tethers for Children (LATCH)
on
page 2‑43for top tether anchor locations.
Do not secure a child seat in a position without a top
tether anchor if a national or local law requires that the
top tether be anchored, or if the instructions that come
with the child restraint say that the top strap must be
anchored.
In Canada, the law requires that forward-facing child
restraints have a top tether, and that the tether be
attached.
You will be using the lap-shoulder belt to secure the
child restraint in this position. Follow the instructions
that came with the child restraint. 1. Move the seat as far back as it will go before securing the forward-facing child restraint.
When the passenger sensing system has turned
off the right front passenger frontal airbag and
seat-mounted side impact airbag, the off indicator
on the passenger airbag status indicator should
light and stay lit when you start the vehicle. See
Passenger Airbag Status Indicator on page 4‑34.
2. Put the child restraint on the seat.
2-53

3. Pick up the latch plate, and run the lap andshoulder portions of the vehicle's safety belt
through or around the restraint. The child restraint
instructions will show you how.
4. Push the latch plate into the buckle until it clicks.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.
5. Pull the rest of the shoulder belt all the way out ofthe retractor to set the lock.
2-54

6. To tighten the belt, push down on the childrestraint, pull the shoulder portion of the belt to
tighten the lap portion of the belt and feed the
shoulder belt back into the retractor. When
installing a forward-facing child restraint, it may be
helpful to use your knee to push down on the child
restraint as you tighten the belt.
7. Push and pull the child restraint in different directions to be sure it is secure. If the airbags are off, the off indicator in the passenger
airbag status indicator will come on and stay on when
the vehicle is started.
If a child restraint has been installed and the on
indicator is lit, see
“If the On Indicator is Lit for a Child
Restraint ”under Passenger Sensing System
on
page 2‑67for more information.
To remove the child restraint, unbuckle the vehicle
safety belt and let it return to the stowed position.

Airbag System
The vehicle has the following airbags:
.A frontal airbag for the driver.
.A frontal airbag for the right front passenger.
.A seat-mounted side impact airbag for the driver.
.A seat-mounted side impact airbag for the right
front passenger.
.A roof-rail airbag for the driver and the passenger
seated directly behind the driver.
.A roof-rail airbag for the right front passenger and
the passenger seated directly behind the right front
passenger.All of the airbags in your vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
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.
2-56

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 2‑61
.
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 your seat or leaning forward.
Safety belts help keep you in position before and
during a crash. Always wear your 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.
2-57

{WARNING:
Children who are up against, or very close to, any
airbag when it inflates can be seriously injured or
killed. Airbags plus lap-shoulder belts offer
protection for adults and older children, but not for
young children and infants. Neither the vehicle's
safety belt system nor its airbag system is
designed for them. Young children and infants
need the protection that a child restraint system
can provide. Always secure children properly in
your vehicle. To read how, seeOlder Children
on
page 2‑33
or Infants and Young Childrenon
page 2‑36
.
There is an airbag readiness light on the instrument
panel 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
on page 4‑33for
more information.
2-58

Frontal airbags may inflate at different crash speeds.
For example:
.If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
.If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed
than if the vehicle hits an object that does not
deform.
.If the vehicle hits a narrow object (like a pole), the
airbags could inflate at a different crash speed
than if the vehicle hits a wide object (like a wall).
.If the vehicle goes into an object at an angle, the
airbags could inflate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specific vehicle design. Frontal airbags are not intended to inflate during vehicle
rollovers, rear impacts, or in many side impacts.
Your vehicle has a seat position sensor which enables
the sensing system to monitor the position of the right
front passenger's seat. The passenger seat position
sensor and passenger safety belt buckle switch provide
information that is used to determine if the airbags
should deploy at a reduced level or at full deployment.
In addition, your vehicle has a dual-stage driver airbag.
Dual-stage airbags adjust the restraint according to
crash severity. Your vehicle has electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more severe
frontal impact. For moderate frontal impacts, dual-stage
airbags inflate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
2-62

Your vehicle also has a dual-depth passenger airbag
that adjusts the restraint according to crash severity,
seat location, and safety belt status using electronic
frontal sensor(s) and other special sensors which
enable the sensing system to monitor the position of the
front passenger seat. The passenger airbag inflates to a
reduced depth when the passenger seat is in a forward
position. For more rearward front seating positions, the
passenger airbag may inflate to an increased depth
(a full deployment), based on safety belt status and the
crash severity measured early in the event. (Always
wear your safety belt, even with frontal airbags.)
Your vehicle has seat-mounted side impact and
roof-rail airbags. SeeAirbag System
on page 2‑56.
Seat-mounted side impact and roof-rail airbags are
intended to inflate in moderate to severe side crashes.
Seat-mounted side impact and roof-rail airbags will
inflate if the crash severity is above the system's
designed threshold level. The threshold level can vary
with specific vehicle design. Seat-mounted side impact and roof-rail airbags are
not intended to inflate in frontal impacts, near-frontal
impacts, rollovers, or rear impacts. A seat-mounted side
impact airbag is intended to deploy on the side of the
vehicle that is struck. Both roof-rail airbags will deploy
when either side of the vehicle is struck.
In any particular crash, no one can say whether an
airbag should have inflated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, inflation is determined by
what the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For seat-mounted side
impact and roof-rail airbags, deployment is determined
by the location and severity of the side impact.
2-63

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 airbag
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.
But airbags would not help in many types of collisions,
primarily because the occupant's motion is not toward
those airbags. SeeWhen Should an Airbag Inflate?
on
page 2‑61for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
2-64

Passenger Sensing System
The vehicle has a passenger sensing system for the
right front passenger position. The passenger airbag
status indicator will be visible on the overhead console
when the vehicle is started.
United StatesCanada
The words ON and OFF, or the symbol for on and off,
are visible during the system check. If you are using
remote start, if equipped, to start the vehicle from a
distance, you may not see the system check. When the
system check is complete, either the word ON or OFF,
or the symbol for on or off, will be visible. See
Passenger Airbag Status Indicator on page 4‑34. The passenger sensing system turns off the right front
passenger frontal airbag and seat-mounted side impact
airbag under certain conditions. The driver airbags and
the roof-rail airbags are not affected by the passenger
sensing system.
The passenger sensing system works with sensors
that are part of the right front passenger seat. The
sensors are designed to detect the presence of a
properly-seated occupant and determine if the right
front passenger frontal airbag and seat‐mounted side
impact airbag should be enabled (may inflate) or not.
According to accident statistics, children are safer when
properly secured in a rear seat in the correct child
restraint for their weight and size.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing child
restraint; a child riding in a forward-facing child seat; an
older child riding in a booster seat; and children, who
are large enough, using safety belts.
