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
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.
Forward Collision Warning Light If

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
(FCW) in Safety for further information.
Stop/Start System Fault Warning Light If
Equipped
This telltale will turn on to indicate the Stop/Start system
is not functioning properly and service is required. Contact
your authorized dealer for service.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is displayed
to indicate that the tire pressure is lower than the recom-
mended value and/or that slow pressure loss is occurring.
In these cases, optimal tire duration and fuel consumption
may not be guaranteed.
