Adaptive Cruise Control
(Optional)
This vehicle may have an Adaptive
Cruise Control with Braking (ACB)
system that enhances the cruise
control function. The adaptive cruise
control system uses a radar sensor to
detect the following distance to vehicles
in front. The system will attempt to
maintain either a safe distance or the
vehicle speed depending on what is
selected by the driver. If a following
distance conflict occurs the system
will alter the vehicles throttle position,
apply engine braking, and even apply
vehicle foundation brakes in attempt to
maintain the following distance. The
driver should always remain alert and
ultimately is the one still responsible
for safe vehicle control.
When the system is active and
controlling the speed and distance, the
screen will show the following display.
