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 ve-
hicle 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.
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.
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 your local authorized
dealer for service. Refer to Forward Collision Warning
