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 272 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 510 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.
