Adaptive Cruise Control
(Advanced)
If equipped with Adaptive Cruise Control

control set speed and following gap. Read
this entire section before using this system.

works like regular cruise control. ACC uses
camera and radar sensors. See
The following gap is the following time (or
distance) between your vehicle and a vehicle
detected directly ahead in your path,
moving in the same direction. If no vehicle
is detected in your path, ACC works like
regular cruise control.
