Tire Messages

CHECK TIRE PRESSURE or
TIRE LOW ADD AIR TO TIRE
If the vehicle has the Tire Pressure
Monitor System (TPMS), this
message displays when the
pressure in one or more of the tires
is low. The low tire pressure warning
light will also come on. See Tire
Pressure Light on page 5 26.
This message will also indicate
which tire needs to be checked.
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. 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 52, Vehicle Load Limits on
page 9 12, and Tire Pressure on
page 10 60.
The DIC also shows the tire
pressure values. See Driver
Information Center (DIC) on
page 5 28.
SERVICE TIRE MONITOR
SYSTEM
If the vehicle has the Tire Pressure
Monitor System (TPMS), this
message displays if a part on the
system 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 26.
Several conditions may cause this
message to appear. See Tire
Pressure Monitor Operation on
page 10 63 for more information.
If the warning comes on and stays
on, there may be a problem with the
TPMS. See your dealer.

If the vehicle has the Tire Pressure
Monitor System (TPMS), this
message displays when the system
is re-learning the tire positions on
the vehicle. See Driver Information
Center (DIC) on page 5 28 for more
information. The tire positions must
be re-learned after rotating the tires
or after replacing a tire or sensor.
