wheel to provide support when backing into an area near a target parking spot,
and when departing from a parallel parking spot. (Changing the shift position
and speed adjustment when moving forward or backing up are not performed
automatically.)
While the IPA is operating, if the system detects an obstacle that could result in a
collision, the emergency brakes operate, regardless of whether the Front and Rear
Parking Assist with Automated Braking function** is on or off.
