information.
Automatic Dimming Mirror
Operation
Automatic dimming reduces the
glare from the headlamps of the
vehicle behind you. The dimming
feature comes on and the indicator
light comes on each time the vehicle
is started.
Cleaning the Mirror
Do not spray glass cleaner directly
on the mirror. Use a soft towel
dampened with water.
Windows
{WARNING
Leaving children, helpless adults,
or pets in a vehicle with the
windows closed is dangerous.
They can be overcome by
the extreme heat and suffer
permanent injuries or even death
from heat stroke. Never leave a
child, a helpless adult, or a pet
alone in a vehicle, especially with
the windows closed in warm or
hot weather.

2-8 Seats and Restraints
Rear Seats
Split Folding Seatbacks
With this feature, either side of the
rear seatback can be folded down
for more cargo space.
{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 safety 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 safety belts are
properly routed and attached, and
are not twisted.
Notice: Folding a rear seat with
the safety belts still fastened may
cause damage to the seat or the
safety belts. Always unbuckle the
safety belts and return them to
their normal stowed position
before folding a rear seat.
1. To fold the seatback down:
The rear safety belts must
be unbuckled and the front
seatbacks are not reclined.
2. Lift the lever located on the topof the seatback.
3. Fold the seatback forward.
Keep the seat in the upright locked
position when not in use.
To recline the seatback:
1. Lift and hold the lever located on top of the seatback.
2. Tilt the seatback rearward, then release the lever when the
seatback is in the desired
position.

Seats and Restraints 2-25
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 the 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 trim.
Even if you do not have a right front
passenger seat in the vehicle there
is still an active frontal airbag in the
right side of the instrument panel.
Do not place cargo in front of this
airbag.
{WARNING
Be sure that cargo is not near an
airbag. In a crash, an inflating
airbag might force that object
toward a person. This could
cause severe injury or even
death. Secure objects away from
the area in which an airbag would
inflate. For more information, see
Where Are the Airbags?
on
page 2‑27
and Vehicle Load
Limits on page 8‑22.
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.

Seats and Restraints 2-31
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.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 2‑29for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.

2-38 Seats and Restraints
If the passenger seat gets wet, dry
the seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to
occupy the seat. SeeAirbag
Readiness Light
on page 4‑15for
important safety information.
The on indicator may be lit if an
object, such as a briefcase,
handbag, grocery bag, laptop or
other electronic device, is put on an
unoccupied seat. If this is not
desired remove the object from
the seat.
{WARNING
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer/retailer and the service
manual have information about
servicing the vehicle and the airbag
system. To purchase a service
manual, see Service Publications
Ordering Information on page 12‑12.
{WARNING
For up to 10 seconds after the
ignition is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
(Continued)
WARNING (Continued)
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto or change about the vehicle
that could keep the airbags
from working properly?
A: Yes. If you add things that
change the vehicle's frame,
bumper system, height, front end
or side sheet metal, they may
keep the airbag system from
working properly. Changing or
moving any parts of the front
seats, safety belts, the airbag
sensing and diagnostic module,

Seats and Restraints 2-53
{WARNING
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck and
the safety belt continues to
tighten. Buckle any unused safety
belts behind the child restraint so
children cannot reach them. Pull
the shoulder belt all the way out
of the retractor to set the lock,
if your vehicle has one, after the
child restraint has been installed.Notice:
Do not let the LATCH
attachments rub against the
vehicle’ s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to
avoid rubbing the LATCH
attachments.
Do not fold the empty rear seat
with a safety belt buckled. This
could damage the safety belt or
the seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.
Make sure to attach the child
restraint at the proper anchor
location.
This system is designed to make
installation of child restraints easier.
When using lower anchors, do not
use the vehicle's safety belts. Instead use the vehicle's anchors
and child restraint attachments to
secure the restraints. Some
restraints also use another vehicle
anchor to secure a top tether.
1. Attach and tighten the lower
attachments to the lower
anchors. If the child restraint
does not have lower
attachments or the desired
seating position does not have
lower anchors, secure the child
restraint with the top tether and
the safety belts. Refer to your
child restraint manufacturer
instructions and the instructions
in this manual.
1.1. Find the lower anchors for the desired seating
position.
1.2. Put the child restraint on the seat.

Seats and Restraints 2-57
4. Pull the rest of the shoulder beltall the way out of the retractor to
set the lock.5. To tighten the belt, push downon the child restraint, 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. 6. If the child restraint has a top
tether, follow the child restraint
manufacturer's instructions
regarding the use of the top
tether. See Lower Anchors and
Tethers for Children (LATCH
System)
on page 2‑49for
more information.
7. Push and pull the child restraint in different directions to be sure
it is secure.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.

2-58 Seats and Restraints
Armrest Retaining Strap
{WARNING
A rear center armrest that is not
properly stowed and secured
could fall forward during a sudden
stop or collision. The armrest
could contact an infant secured
in a rear‐facing child restraint in
the center seat position. Fasten
the retaining strap onto the
stowed armrest before installing
a rear‐facing child restraint in the
rear center seat position.
When new, the vehicle's glove box
materials included an armrest
retaining strap. Use it to secure thecenter armrest before installing a
rear‐facing child restraint in the
second row center seat position.
Stow the rear seat center armrest.
Attach the retaining strap to the
armrest loop (A) and to the center
top tether anchor on the
seatback (B). Make sure the
retaining strap's clips are firmly
attached.
Install the rear-facing child
restraint using the child restraint
manufacturer's instructions and the
instructions described previously.Remove the armrest retaining strap
before installing a forward facing
child restraint in the center seat
position, as it may interfere with the
attachment of the top tether to the
top tether anchor on the seatback.
Securing Child Restraints
(Front Passenger Seat)
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint
on
page 2‑47.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the right front
passenger frontal airbag under
certain conditions. See Passenger
Sensing System
on page 2‑33and
Passenger Airbag Status Indicator
on page 4‑15for more information,
including important safety
information.
