Cruise Control
A
d
aptive Cruise Control
If equipped, Adaptive Cruise Control (ACC)
allows the cruise control set speed and
following gap to be selected. 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 camera and
radar sensors.
If avehicle is detected in your path, ACC
can speed up the vehicle or apply 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
system activates, ACC may automatically
disengage. See Traction Control/Electronic
Stability Control 3178. When road conditions
allow ACC to be safely used, ACC can be turned
back on.
Disabling the TCS or StabiliTrak/ESC system will
disengage and prevent engagement of ACC.
ACC can reduce the need for you to frequently
br
ake and accelerate, especially when used
on expressways, freeways, and interstate
highways. When used on other roads, you
may need to take over the control of braking or
acceleration more often.
{ Warning
A
CC has limited braking ability and may
no
t 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 this section. Complete attention
is always required while driving and you
should be ready to take action and apply the
brakes. See Defensive Driving 3154.

Do not use ACC when:
(Continued)
Warning (Continued)
•
On
winding and hilly roads or when the
sensors are blocked by snow, ice, or dirt.
The system may not detect avehicle
ahead. Keep the entire front of the
vehicle clean.
•
Visibility is poor due to rain, snow, fog,
dirt, insect residue, or dust; when other
foreign objects obscure the camera
and/or radar; or when the vehicle
in front or oncoming traffic causes
additional environmental obstructions,
such as road spray. ACC performance is
limited under these conditions.
•
On slippery roads where fast changes
in tire traction can cause excessive
wheel slip.
•
Towing atrailer
