23. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first placed in the RUN position and
remain on briefly as a bulb check. If the light stays on or
comes on while driving, turn off some of the vehicle’s
non-essential electrical devices or increase engine speed
(if at idle). If the charging system light remains on, it
means that the vehicle is experiencing a problem with the
charging system. Obtain SERVICE IMMEDIATELY. See
an authorized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.
24. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD. The
OBD system monitors engine and automatic
transmission control systems. The MIL will turn on when
the ignition is placed in the RUN position before engine
start. If the MIL does not come on when turning the
ignition from the OFF to RUN position, have the condi-
tion checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the MIL
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 MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability. If the MIL is
flashing, severe catalytic converter damage and
power loss will soon occur. Immediate service is
required.
