Other information:
During vehicle start up, when the ParkSense
Rear Park Assist System has detected a faulted

The HSA system is designed to mitigate roll
back from a complete stop while on an incline.
If the driver releases the brake while stopped on
an incline, HSA will continue to hold the brake
pressure for a short period. If the driver does
not apply the throttle before this time expires,
the system will release brake pressure and the
vehicle will roll down the hill as normal...
