Tire Pressure Light
This light will come on
briefly when you turn
the ignition to RUN.
This light will also come on when one or more of
your tires are significantly underinflated.
If your vehicle has a Driver Information Center
(DIC), a CHECK TIRE PRESSURE DIC message
will accompany the light. See DIC Warnings and
Messages on page 270 for more information.
Stop and check your tires as soon as it is safe to do
so. If underinflated, inflate to the proper pressure.
See Tires on page 507 for more information.
This light will flash for 60 seconds and then turn on
solid if a problem is detected with the Tire Pressure
Monitor system.
See Tire Pressure Monitor System on page 516 for
more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has 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 check engine 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.
