•Do not place items over the
climate temperature sensor grid.
This may cause improper
operation of the system.
To aid in side window defogging/demisting in cold weather:
1. Select
.
2. Ensure that recirculation is disengaged.
3. Set the temperature control to full heat.
4. Set the fan to the highest speed.
5. Direct the outer instrument panel vents towards the side windows.
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.
REAR WINDOW DEFROSTER
Press the rear window defroster
control to clear the rear window of
thin ice or fog. The light above the
control will illuminate to indicate
that the rear defrost is operating.
The ignition must be in the RUN position and the engine running in
order to operate the rear window defroster.
The rear window defroster turns off automatically after a predetermined
amount of time, if a low battery condition is detected, or if the ignition is
turned to the OFF position. To manually turn off the rear window
defroster at any time, press the control again.
Do not use razor blades or other sharp objects to clean the inside
of the rear window or to remove decals from the inside of the
rear window. This may cause damage to the heated grid lines and
will not be covered by your warranty.

When to use the automatic locking mode
•Anytimea child safety seat is installed in the vehicle. Refer toSafety
Restraints for ChildrenorSafety Seats for Childrenlater in this
chapter.
How to disengage the automatic locking mode
Unbuckle the combination lap and shoulder belt and allow it to retract
completely to disengage the automatic locking mode and return to the
vehicle sensitive (emergency) locking mode.
After any vehicle collision, the combination lap and shoulder belt
system at all passenger seating positions must be checked by a
qualified technician to verify that the“automatic locking retractor”
feature for child seats is still functioning properly, in addition to other
checks for proper seat belt system function.
BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the safety belt assembly“automatic locking retractor”feature or
any other safety belt function is not operating properly. In addition, all
safety belts should be checked for proper function. Failure to replace
the belt and retractor assembly could increase the risk of injury in
collisions.
Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
front passenger seating positions.
The safety belt pretensioner is a device which removes excess webbing
from the safety belt system. The safety belt pretensioner uses the same
crash sensor system as the front air bag supplemental restraint system
(SRS). When the safety belt pretensioner deploys, webbing from the lap
and shoulder belt is tightened. The driver and front passenger seat belt
system (including retractors and buckles) must be replaced if the vehicle
is involved in a collision that results in deployment of front air bags and
safety belt pretensioners. Refer to theSafety belt maintenancesection
in this chapter.
Failure to replace the safety belt assembly under the above
conditions could result in severe personal injuries in the event of
a collision.

How does the safety belt pretensioner and air bag supplemental
restraint system work?
The safety belt pretensioner and air
bag SRS are designed to activate
when the vehicle sustains longitudinal
deceleration sufficient to cause the
sensors to close an electrical circuit
that initiates pretensioner activation
and air bag inflation.
The fact that the pretensioners and
air bags did not activate in a collision
does not mean that something is
wrong with the system. Rather, it
means the forces were not of the type sufficient to cause activation. Front
air bags and pretensioners are designed to activate in frontal and
near-frontal collisions, not rollover, side-impact, or rear-impacts unless the
collision causes sufficient longitudinal deceleration.
The air bags inflate and deflate
rapidly upon activation. After air bag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
air bag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, contact with
a deploying air bag may also cause abrasions, swelling or temporary
hearing loss. Because air bags must inflate rapidly and with considerable
force, there is the risk of death or serious injuries such as fractures,
facial and eye injuries or internal injuries, particularly to occupants who
are not properly restrained or are otherwise out of position at the time
of air bag deployment. Thus, it is extremely important that occupants be
properly restrained as far away from the air bag module as possible while
maintaining vehicle control.

Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag has deployed,the air bag will not function
again and must be replaced immediately.If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
The SRS consists of:
•driver and passenger air bag modules (which include the inflators and
air bags)
•side air bags. Refer toSide air bag systemlater in this chapter
•safety belt pretensioners
•one or more impact and safing sensors
•a readiness light and tone
•and the electrical wiring which connects the components
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system wiring (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power, the air bag ignitors and safety belt pretensioners.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAir bag readiness
section in theInstrument clusterchapter. Routine maintenance of the
air bag is not required.
Any difficulty with the system is indicated by one or more of the
following:
•The readiness light will either
flash or stay lit
•The readiness light will not
illuminate immediately after
ignition is turned to the RUN position
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.

How does the side air bag system work?
The side air bag system consists of
the following:
•An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
•A special seat cover designed to
allow air bag deployment.
•The same warning light,
electronic control and diagnostic unit as used for the front air bags.
•Two crash sensors located under the outboard side of the front seats,
attached near the floor.
Side air bags, in combination with seat belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated, even if the respective seat is not
occupied. The air bag was designed to inflate between the door panel
and occupant to further enhance the protection provided occupants in
side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates air bag inflation.
The fact that the air bags did not inflate in a collision does not mean that
something is wrong with the system. Rather, it means the forces were
not of the type sufficient to cause activation. Side air bags are designed
to inflate in side-impact collisions, not roll-over, rear-impact, frontal or
near-frontal collisions, unless the collision causes sufficient lateral
deceleration.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
