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.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag is inflated,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:
²driver and passenger air bag modules (which include the inflators and
air bags),
²one or more impact and safing sensors,
²a readiness light and tone
²and the electrical wiring which connects the components.
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
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

Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
Failure to follow these precautions may adversely affect the
handling of the vehicle and make it easier to lose control and roll
over.
Tires that are larger or smaller than your vehicle's original tires may also
affect the accuracy of your speedometer.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use snow tires and chains, you must
install steel wheels of the same size and specifications as those originally
installed.
Follow these guidelines when using snow tires and chains:
²Use only SAE Class S chains.
²Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
