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 readiness (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 readinesssection in
theInstrumentationchapter. Routine maintenance
of the air bag is not required.
A difficulty with the system is indicated by one or
more of the following:
²The readiness light
will either flash or
stay lit.
²The readiness light
will not illuminate immediately after ignition is
turned on.
²A group of five beeps will be heard. The tone
pattern will repeat periodically until the problem
and light are repaired.

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
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. 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.
²Do not use tire chains on aluminum wheels.
²Do not use tire chains if your vehicle is equipped
with P225/55VR16 tires.
²Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
