TIRE LOW ADD AIR TO TIRE
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 5 23. 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 odometer reset
stem. If a tire pressure message
appears on the DIC, stop as soon
as you can. Have the tire pressures
checked and set to those shown on
the Tire Loading Information label.
See Tires on page 10 44, Vehicle
Load Limits on page 9 15, and Tire
Pressure on page 10 51. The DIC
also shows the tire pressure values.
See DIC Operation and Displays
(With DIC Buttons) earlier in this
section.
