10. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL)
is part of an onboard diagnostic sys-
tem called OBD II that monitors en-
gine and automatic transmission con-
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, poor fuel quality, etc., may
illuminate the light after engine start. The ve-
hicle 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

CAUTION!
(Continued)
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.
11. Rear Fog Lights
This indicator will illuminate when the
rear fog lights are on.
12. Temperature Gauge
The temperature gauge shows engine coolant
temperature. Any reading within the normal
range indicates that the engine cooling system
is operating satisfactorily.
The gauge pointer will likely indicate a higher
temperature when driving in hot weather, up
mountain grades, or when towing a trailer. It
should not be allowed to exceed the upper limits
of the normal operating range.
CAUTION!
Driving with a hot engine cooling system
could damage your vehicle. If the tempera-
ture gauge reads “H” pull over and stop the
vehicle. Idle the vehicle with the air condi-
tioner turned off until the pointer drops back
into the normal range. If the pointer remains
on the “H” and you hear continuous chimes,
turn the engine off immediately and call an
authorized dealer for service.
