If there is a brake system problem that is specifically
related to traction control, the traction control
system will turn off, the warning light will come on
and the chime will sound.

If the traction control system is affected by an
engine-related problem, the system will turn off, the
warning light will come on and the chime will sound.

If the traction control system warning light comes on and
stays on for an extended period of time when the
system is turned on, your vehicle needs service.

Engine Coolant Temperature Gage

This gage measures the
temperature of the
vehicle’s engine. If the
pointer moves into
the shaded area, the
engine is too hot. A
temperature indicator light
will turn on and a chime
will sound.

If you have been operating your vehicle under normal
driving conditions, and the temperature indicator
light comes on, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.

Malfunction Indicator Lamp

Service Engine Soon Light

Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.

This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.

Notice: If you keep driving your vehicle with this
light on, after a while, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
