This message displays if a part on
the Tire Pressure Monitor System
(TPMS) is not working properly.
The tire pressure light also flashes
and then remains on during the
same ignition cycle. See Tire
Pressure Light on page 5‑24.
Several conditions may cause
this message to appear. See Tire
Pressure Monitor Operation on
page 10‑75 for more information.
If the warning comes on and stays
on, there may be a problem with the
TPMS. See your dealer.
TIRE LEARNING ACTIVE
This message displays when the
Tire Pressure Monitor System
(TPMS) is re-learning the tire
positions on the vehicle. The tire
positions must be re-learned after
rotating the tires or after replacing a
tire or sensor. See Tire Rotation on
page 10‑79, Tire Pressure Monitor
System on page 10‑74, and Tire

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 is low. This message
also displays LEFT FRONT, RIGHT
FRONT, LEFT REAR, or 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 5‑24.
If a tire pressure message appears
on the DIC, stop as soon as you
can. Inflate the tires by adding air
until the tire pressure is equal to the
values shown on the Tire Loading
Information label. See Tires on
page 10‑64, Vehicle Load Limits on
page 9‑11, and Tire Pressure on
page 10‑72.
If the vehicle does not have a spare
tire, the message will display “Use
Inflator Kit in Trunk”. Use the inflator
kit to inflate the tires to the correct
pressure. See Tire Sealant and
Compressor Kit on page 10‑89 for
more information.
More than one tire pressure
message can be received at a
time. To read the other messages,
press the set/reset button.
The DIC display also shows the
tire pressure values. See Driver
Information Center (DIC) on
page 5‑27.
