Engine Temperature Warning Light
Red WarningLight What It Means
Engine Temperature Warning Light
This light warns of an overheated engine condition. As engine coolant temperatures rise and
the gauge approaches
H, this indicator will illuminate and a single chime will sound after
reaching a set threshold. Further overheating will cause a continuous chime sound for
4 minutes, or until the engine is allowed to cool, whichever comes first.
If the light turns on while driving, safely pull over and stop the vehicle. If the A/C system
is on, turn it off. Also, shift the transmission into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To Do In Emergencies” for further
information.

Yellow Telltale Indicator Lights
Engine Check/Malfunction Indicator Light (MIL)
Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic Sys-
tem called OBD II that monitors engine and automatic transmission control systems. The light
will illuminate when the ignition is in the ON position before engine start. If the bulb does not
come on when turning the key from OFF to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap, poor quality fuel, etc., may illuminate
the light after engine start. The vehicle should be serviced if the light stays on through several
typical driving styles. In most situations, the vehicle will drive normally and will not require
towing.
When the engine is running, the MIL may flash to alert serious conditions that could lead to
immediate loss of power or severe catalytic converter damage. The vehicle should be serviced
as soon as possible if this occurs.
314 UNDERSTANDING YOUR INSTRUMENT PANEL

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
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.

This light monitors the Anti-Lock Brake System (ABS). The light will turn on when the
ignition is placed in the ON/RUN position and may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, then the Anti-Lock portion of the
brake system is not functioning and service is required. However, the conventional brake
system will continue to operate normally if the brake warning light is not on.
If the ABS light is on, the brake system should be serviced as soon as possible to restore the
benefits of Anti-Lock Brakes. If the ABS light does not turn on when the ignition is placed in
the ON/RUN position, have the light inspected by an authorized dealer.
