When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags
will or should deploy is not based on how fast your
vehicle is traveling. It depends largely on what you hit,
the direction of the impact and how quickly your
vehicle slows down.
In addition, your vehicle has “dual stage” frontal airbags,
which adjust the restraint according to crash severity.
Your vehicle is equipped with electronic frontal sensors
which help the sensing system distinguish between a
moderate and a more severe frontal impact. For
moderate frontal impacts, these airbags inate at a level
less than full deployment. For more severe frontal
impacts, full deployment occurs. If the front of your
vehicle goes straight into a wall that does not move or
deform, the threshold level for the reduced deployment
is about 10 to 16 mph (16 to 25 km/h), and the
threshold level for a full deployment is about20 to 30 mph (32 to 48 km/h). (The threshold level can
vary, however, with specic vehicle design, so that it can
be somewhat above or below this range.)
Airbags may inate at different crash speeds. For
example:
If the vehicle hits a stationary object, the airbag
could inate at a different crash speed than if
the object were moving.
If the object deforms, the airbag could inate at a
different crash speed than if the object does not
deform.
If the vehicle hits a narrow object (like a pole) the
airbag could inate 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
airbag could inate at a different crash speed
than if the vehicle goes straight into the object.
The frontal airbags (driver and right front passenger) are
not intended to inate during vehicle rollovers, rear
impacts, or in many side impacts because ination
would not likely help the occupants.
Vehicles with dual stage airbags are also equipped with
special sensors which enable the sensing system to
monitor the position of both the driver and passenger
front seats. The seat position sensor provides
information which is used to determine if the airbags
should deploy at a reduced level or at full deployment.

Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my advanced airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module (located under the driver’s seat), or
the inside rearview mirror can affect the operation
of the advanced airbag system. If you have
questions, call Customer Assistance. The phone
numbers and addresses for Customer Assistance
are in Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 7-2.
Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken airbag covers, and
have them repaired or replaced. (The airbag system
does not need regular maintenance.)

{CAUTION:
If the removable rear glass is not stored
properly, it could be thrown about the vehicle
in a crash or sudden maneuver. People in the
vehicle could be injured. Whenever you store
the rear glass in the vehicle, always be sure
that it is stored securely in the midgate
storage pocket.
Do not remove the rear glass when the rear defroster is
on. If you remove the rear glass with the rear defroster
on, you may see a discharge spark coming from
the latch area.
To remove the rear glass do the following:
1. Fold the rear seats. SeeRear Seat Operation on
page 1-7for more information. The front seats
may have to be moved forward slightly to allow the
rear seats to fold completely.
Although the rear glass can be removed without
folding the rear seats, you will not be able to access
the rear glass storage pocket. Be sure to fold the
seats before removing the rear glass.

6. Turn both glass lock knobs (D), located at both top
corners of the storage pocket, to the locked
position. Push in on the corner of the rear glass to
allow the lock knob to engage more easily.Once both glass lock knobs are in the locked
position, the rear glass is securely stored.
7. Push both latch levers up to the locked position.
You should hear a click when each latch lever
locks correctly.
The rear seats can be returned to the normal
position when the rear glass is out and stored
properly in the storage pocket.

Lowering the Midgate with the Rear Glass
in Place
The midgate can be lowered to allow the cargo area of
your vehicle to extend into the cab. The rear glass
can be either installed in its normal position, or it can be
removed and stored in the rear glass storage pocket.
To lower the midgate, do the following:
1. Fold the rear seats. The front seats might have to
be moved forward slightly to allow the rear seats to
fold. SeeRear Seat Operation on page 1-7for
more information.
2. Standing outside of the vehicle, hold the midgate
securely so it does not fall forward. Turn the
midgate handle clockwise and pull the midgate
toward you.Rear Glass in Normal Position

If the mirrors are accidentally folded/unfolded manually,
they may shake or utter at normal driving speeds
and may not stay in the unfolded position. If this
happens, the mirrors need to be reset. See “Resetting
the Power Folding Mirrors” next.
Resetting the Power Folding Mirrors
The power folding mirrors will need to be reset if:
They are accidently manually folded/unfolded.
The mirrors will not stay in the unfolded position.
The mirrors shake and utter at normal driving
speeds.
To reset the power folding mirrors, fold and unfold them
at least three times using the mirror controls. This will
reset them to their normal detent position.

Center Console Storage Area
Your vehicle may have a console compartment with
cupholders between the bucket seats.
To open it, press the button and swing the console
lid open.
The rear of the console has a cupholder that swings
down for the rear seat passenger to use.
Luggage Carrier
You can load things on top of your vehicle if it has this
feature.
The luggage carrier has slats and siderails attached to
the roof and may have crossrails which can be moved
back and forth to help secure cargo. Tie the load to the
siderails or siderail supports.
Notice:Loading cargo on the luggage carrier that
weighs more than 200 lbs (91 kg) or hangs over
the rear or sides of the vehicle may damage your
vehicle. Load cargo so that it rests on the slats
as far forward as possible and against the side rails,
making sure to fasten it securely.Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, seeLoading Your Vehicle on
page 4-47.
To prevent damage or loss of cargo as you’re leaving,
check now and then to make sure the luggage and
cargo are still securely fastened.
Be sure the cargo is properly loaded.
If small heavy objects are placed on the roof cut a
piece of 3/8 inch plywood to t inside the crossrails
and siderails to spread the load. If plywood is
used, tie it to the siderail supports.
Tie the load to the crossrails or the siderail supports.
Use the crossrails only to keep the load from
sliding. To move the crossrails, pull out on the latch
release handle at each end. Slide the crossrail to
the desired position balancing the force side to side.
Push the release handle back into the latched
position and slide the crossrail back and forth
slightly to be sure the latch snaps securely into
place.

Rear Window Defogger
If your vehicle has this feature, the lines you see on the
rear window warm the glass. The rear window
defogger uses a warming grid to remove fog from the
rear window.
<(Rear):Press this button to turn the rear window
defogger on or off. An indicator light in the button
will come on to let you know that the rear window
defogger is activated.
The rear window defogger will turn off about 10 minutes
after the button is pressed. If you need additional
warming time, press the button again.
If your vehicle is equipped with heated mirrors this
button will activate them.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.
Outlet Adjustment
Your vehicle has air outlets located in the center and on
the side of your instrument panel that allow you to
adjust the direction and amount of airow inside the
vehicle. Move the louvers up or down. Use the
thumbwheel next to or underneath the outlet to close
the louvers. For the most efficient airow and
temperature control, keep the outlet in the fully opened
position.
Operation Tips

Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
Keep the air path under the front seats clear
of objects. This helps air to circulate throughout your
vehicle.
Adding outside equipment to the front of your
vehicle, such as hood-air deectors, etc., may affect
the performance of the heating and air conditioning
system. Check with your dealer before adding
equipment to the outside of your vehicle.
