call an authorized dealer for service if your
vehicle overheats. If you decide to look un-
der the hood yourself, see "Maintaining Your
Vehicle". Follow the warnings under the
Cooling System Pressure Cap paragraph.
16. Air Bag Warning Light
This light will turn on for four to
eight seconds as a bulb check
when the ignition switch is first
turned to the ON/RUN position. If
the light is either not on during
starting, stays on, or turns on while driving, have
the system inspected at an authorized dealer as
soon as possible. Refer to "Occupant Re-

trol systems. The light will illuminate when the
key is in the ON/RUN position before engine
start. If the bulb does not come on when turning
the key from OFF to ON/RUN, have the condi-
tion checked promptly.
Certain conditions, such as a loose or missing
gas cap, poor fuel quality, etc., may illuminate
the light after engine start. The vehicle should
be serviced if the light stays on through several
of your typical driving cycles. In most situations,
the vehicle will drive normally and will not
require towing.
CAUTION!
Prolonged driving with the Malfunction Indi-
cator 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 converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
A malfunctioning catalytic converter, as ref-
erenced above, can reach higher tempera-
tures 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 re-
sult in death or serious injury to the driver,
occupants or others.
18. Vehicle Security Light
This light will flash rapidly for ap-
proximately 15 seconds when the
vehicle theft alarm is arming. The
light will flash at a slower speed
continuously after the alarm is set.
The security light will also come on for about three
seconds when the ignition is first turned on.
