Turning the System On and Off
The URPA system can be turned on and off using the park assist button located next to the shift lever.

The LED next to the park assist button lights up when the system is on and turns off when it has been disabled.
When the system is off, PARK ASSIST OFF displays on the Driver Information Center (DIC). The message disappears after a short period of time.
URPA defaults to the on setting each time the vehicle is started.
