When Should an Air Bag Inate?
Frontal Air Bags
The driver’s and right front passenger’s frontal air bags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
only if the impact speed is above the system’s
designed “threshold level.”
In addition, your vehicle has “dual stage” frontal air bags,
which adjust the amount of restraint according to crash
severity. For moderate frontal impacts, these air bags
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 doesn’t 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 about 20 to 25 mph
(32 to 40 km/h). The threshold level can vary, however,
with specic vehicle design, so that it can be somewhat
above or below this range.
If your vehicle strikes something that will move or
deform, such as a parked car, the threshold level will be
higher. The driver’s and right front passenger’s frontal
air bags are not designed to inate in rollovers, rear
impacts, or in many side impacts because ination
would not help the occupant.
Seat Position Sensors
Vehicles with dual stage air bags 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 air bags
should deploy at a reduced level or at full deployment.
Side Impact Air Bags
Your vehicle may or may not have a side impact air
bag. SeeAir Bag Systems on page 1-74. Side impact air
bags are designed to inate in moderate to severe
side crashes. A side impact air bag will inate if
the crash severity is above the system’s designed
“threshold level.” The threshold level can vary with
specic vehicle design. Side impact air bags are
not designed to inate in frontal or near-frontal impacts,
rollovers or rear impacts, because ination would not
help the occupant. A side impact air bag will only deploy
on the side of the vehicle that is struck.

Adding Equipment to Your Air
Bag-Equipped Vehicle
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the air
bags from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end or side sheet
metal or height, they may keep the air bag system
from working properly. Also, the air bag system
may not work properly if you relocate any of the air
bag sensors. If you have any questions about
this, you should contact Customer Assistance
before you modify your vehicle. 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.
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my advanced air bag system?
A:Changing or moving any parts of the front seats,
safety belts, the air bag sensing and diagnostic
module (located under the driver’s seat), or
the inside rearview mirror can affect the operation
of the advanced air bag 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 Your 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 air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Outside Power Camper-Type Mirror
If your vehicle is equipped with outside power
camper-type mirrors, they can be adjusted so you can
have a clear view of objects behind you.
To extend the mirrors move the selector switch, located
above the mirror control, to the middle position. The
mirror control will illuminate. Press the left side of
the mirror control to slide the mirror heads away from
the body of the vehicle. Press the right side of the mirror
control to slide the mirror heads toward the body of
the vehicle.
Outside Power Foldaway Mirrors
If your vehicle is equipped
with this feature, the
controls are located on the
driver’s door armrest.Move the upper selector switch to the left or right to
choose the mirror you want to adjust; then press
the dots located on the four-way control pad to adjust
the mirror.
The mirrors may also include a memory function which
works together with the memory seats. See “Memory
Seats” underMemory Seat on page 2-67for more
information.
To fold or unfold the mirrors, move the selector switch,
located above the mirror control, to the middle
position. The mirror control will illuminate. Press the
right or left side of the mirror control to fold or unfold the
mirrors. You may notice the mirror glass adjust as the
mirrors fold in; this is normal. The mirror glass will
reposition itself once the mirrors are unfolded.
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, you will need to reset the mirrors. See
“Resetting the Power Foldaway Mirrors” next.

Storage Areas
Glove Box
To open your glove box, lift up the latch and pull the
door open.
Cupholder(s)
Your vehicle may have cupholders located in the front
and rear oor console or in the fold down armrest, and in
the quarter trim.
Front Storage Area
Your vehicle may be equipped with a center armrest
storage compartment in the front bench seat.
To open it, fold down the armrest and press the latch
handle located at the front of the armrest. Then, let the
lid pop up and swing open.
The storage compartment may have a cassette/compact
disc holder.
Center Console Storage Area
Your vehicle may be equipped with a console
compartment between the bucket seats.
To open it, press the button and swing the console
lid open.
The console has a place to store coins.
Your console has a cupholder that swings down for the
rear seat passengers to use.
Luggage Carrier
If you have the luggage carrier, you can load things on
top of your vehicle.
The luggage carrier has slats and siderails attached to
the roof and 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. (918 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.

Outlet Adjustment
Use the air outlets located
in the center and on the
side of your instrument
panel to direct the airow.
Your vehicle has air outlets 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.
Rear seat outlets can be used to adjust airow toward
either seating area, the oor or upward. Move the center
louvers up or down to direct the airow.
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.

Rear Air Conditioning and Heating
System
If your vehicle is equipped with this system, there are
two rear heat and air conditioning controls. One control
is located in the overhead console and the other is
located in the headliner above the second row seats.
The system can be controlled from the front controls as
well as the rear controls.
The front control has three knobs that control airow
speed, temperature and airow location.
Fan Knob
The fan knob on the left side of the control panel
adjusts the fan speed. To increase airow, turn the knob
