Start the TPMS Calibration Process
This vehicle has an indirect TPMS. Unlike other systems that directly measure air pressure, an indirect TPMS uses the
VSA wheel speed sensors to monitor and compare tire characteristics while driving and determine when one or more
tires are significantly underinflated.
To ensure proper operation, you must inflate all four tires to the cold inflation pressures listed on the driver's doorjamb
label and start the TPMS calibration process during the PDI using the method below.
1. Start the engine, and park the vehicle in an open area away from trees, power lines, and tall buildings. Remove
loose articles, cell phones, and electrical accessories near the GPS antenna. If you see this screen, press and
hold the audio power button to bypass it.
2. You will then see this screen, telling you the system is initializing (acquiring its location from the GPS satellites).
Keep watching the screen.
NOTE: Initialization averages about 10 minutes, but it can take as long as 45 minutes. If it completes within
10 minutes, the screen changes to the globe screen.
3. If the system does not initialize within 10 minutes, a second screen (shown below) appears. The system is still
initializing, but it will not automatically change to the globe screen when the initialization is complete. Do not
follow the screen instructions right away. After 30 minutes, try restarting the engine to see if the system
completed the initialization. If it did not, then follow the screen instructions.
NOTE: The initialization screen may appear after battery voltage to the audio-navigation unit has been
disconnected for more than 5 minutes. If that happens, follow the screen instructions. If you are still unable to
get GPS initialization, do a search in the service information using keyword GPS.
