turns on the Air Bag Warning Light, either momentarily
or continuously. A single chime will sound if the light
comes on again after initial startup.
It also includes diagnostics that will illuminate the instru-
ment cluster Air Bag Warning Light if a malfunction is
noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
to protect you in a collision. If the light does not come
on as a bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it comes
on as you drive, have an authorized dealer service the
air bag system immediately.
Driver And Passenger Advanced Front Air Bag
Inflator Units
The Driver and Passenger Advanced Front Air Bag
Inflator Units are located in the center of the steering
wheel and on the right side of the instrument panel.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag inflation rates
are possible, based on several factors, including the
collision type and severity. The steering wheel hub trim
cover and the upper right side of the instrument panel
separate and fold out of the way as the air bags inflate to
their full size. The air bags fully inflate in about 50 to 70
milliseconds. This is about half of the time it takes to
blink your eyes. The air bags then quickly deflate while
helping to restrain the driver and front passenger.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 75

Multifunction Lever
The multifunction lever is located on the left side of the
steering column.
Turn Signals
Move the multifunction lever up or down and the arrows
on each side of the instrument cluster flash to show
proper operation of the front and rear turn signal lights.NOTE:If either light remains on and does not flash, or
there is a very fast flash rate, check for a defective outside
light bulb. If an indicator fails to light when the lever is
moved, it would suggest that the indicator bulb is
defective.

testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
(Continued)
CAUTION!(Continued)
converter damage and power loss will soon occur.
Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
4. Turn Signal Indicators The arrow will flash with the exterior turn
signal when the turn signal lever is operated.4
UNDERSTANDING YOUR INSTRUMENT PANEL 279
Page 282 of 790

NOTE:•A continuous chime will sound if the vehicle is
driven more than 1 mile (1.6 km) with either turn
signal on.
• Check for an inoperative outside light bulb if either
indicator remains on and does not flash, or flashes at
a rapid rate.
5. Voltmeter
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. If
the pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced. NOTE:
The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of the
cycling operation is controlled by the engine control
module. Post-heat operation can run for several minutes,
and then the electrical system and voltmeter needle will
stabilize.
6. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the Anti-lock Brake System reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake

VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
•Disconnect the negative cable from battery.
• Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
REPLACEMENT BULBS
All of the inside bulbs are brass or glass-wedge base.
Aluminum base bulbs are not approved.
