102 GETTING TO KNOW YOUR INSTRUMENT PANEL
Engine Check/Malfunction Indicator
Warning Light
The Engine Check/Malfunction
Indicator Light (MIL) is a part of an
Onboard Diagnostic System called
OBD II that monitors engine and
automatic transmission control systems.
This warning light will illuminate when the
ignition is in the ON/RUN position before engine
start. If the bulb does not come on when turning
the ignition switch 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 by an authorized dealer as soon
as possible if this occurs.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to
signal a fault with the 4WD system.
If the light stays on or comes on
during driving, it means that the 4WD
system is not functioning properly and that
service is required. We recommend you drive to
the nearest service center and have the vehicle
serviced immediately.
Service Forward Collision Warning (FCW)
Light — If Equipped
This telltale will turn on to indicate a
fault in the Forward Collision Warning
System. Contact an local authorized
dealer for service Ú page 277.
Service Stop / Start System Warning Light
This telltale will turn on to indicate the
Stop/Start system is not functioning
properly and service is required. Contact
an authorized dealer for service.
Cruise Control Fault Warning Light
This warning light will illuminate to
indicate the Cruise Control System is
not functioning properly and service is
required. Contact an authorized dealer.
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.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause damage
to the vehicle 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.
