CHECK TIRE PRESSURE
If the vehicle has ABS brakes, this warning message
will appear when the air pressure in one of the tires
is too low or too high. Check the vehicle's tire pressure
as soon as possible, and fill the affected tire to the
appropriate level. The correct tire inflation pressure
should be set to those shown on the tire-loading
information label on the vehicle. See Loading Your
Vehicle on page 4-35 for more information.

System" in the options section under DIC Controls and
Displays on page 3-45 for more information.

acknowledged when the engine is turned off. It will
also re-display for three seconds if the message has
been acknowledged, but the condition still exists
when the engine is turned off.
The message will re-appear when the engine is turned
on and the condition still exists.
