Tire Messages


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 5‑30. Several conditions may cause this message to appear. See Tire Pressure Monitor Operation on page 10‑65 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 your vehicle. The tire positions must be re-learned after rotating the tires or after replacing a tire or sensor.

See Tire Inspection on page 10‑68, Tire Rotation on page 10‑68, Tire Pressure Monitor System on page 10‑64, and Tire Pressure on page 10‑62 for more information.


If the vehicle has 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 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 5‑30. 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 10‑54, Vehicle Load Limits on page 9‑17, and Tire Pressure on page 10‑62. The DIC also shows the tire pressure values. See Driver Information Center (DIC) on page 5‑33.
