Adaptive Cruise Control
If equipped, Adaptive Cruise Control
(ACC) allows the driver to select the
cruise control set speed and
following gap. Read this entire
section before using this system.
The following gap is the following
time 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. ACC uses a radar
sensor. See Radio Frequency
Statement 0 324.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle
speed when the Traction Control
System (TCS) or StabiliTrak/
Electronic Stability Control (ESC)
activates, the ACC may
automatically disengage. When road
conditions allow ACC to be safely
used, the ACC can be turned back
on. If TCS or StabiliTrak/ESC have
been disabled, the ACC will not
engage. See Traction Control/
Electronic Stability Control 0 185.
{
Warning
ACC has limited braking ability
and may not have time to slow
the vehicle down enough to avoid
a collision with another vehicle
you are following. This can occur

when vehicles suddenly slow or
stop ahead, or enter your lane.
Also see “Alerting the Driver” in

action and apply the brakes. See
Defensive Driving 0 162.

a vehicle ahead. Keep the
entire front of the vehicle
clean.
