Tire Pressure
If the vehicle has the Tire Pressure Monitor System (TPMS), the pressure for each tire can be viewed in the DIC. The tire pressure will be shown in either kilopascals (kPa) or pounds per square inch (psi). Press the vehicle information button until the DIC displays FRONT TIRES kPa (PSI) LEFT ## RIGHT ##. Press the vehicle information button again until the DIC displays REAR TIRES kPa (PSI) LEFT ## RIGHT ##.
If a low tire pressure condition is detected by the system while driving, a message advising you to add pressure in a specific tire will appear in the display. See Tire Pressure on page 10‑62 and Tire Messages on page 5‑49 for more information.
If the tire pressure display shows dashes instead of a value, there may be a problem with the vehicle.
If this consistently occurs, see your dealer for service.
