On vehicles with the Tire Pressure Monitor System
(TPMS), this message displays when the pressure in
one or more of the vehicle's tires needs to be checked.
This message also displays LEFT FRT (left front),
RIGHT FRT (right front), LEFT RR (left rear), or RIGHT
RR (right rear) to indicate the location of the low tire.
The low tire pressure warning light will also come on.
See Tire Pressure Light on page 4 39. You can receive
more than one tire pressure message at a time. To read
the other messages that may have been sent at the
same time, press the set/reset button or the trip
