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. See
Radio Frequency Statement 0 409.
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 the
Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates while ACC is
engaged, ACC may automatically
disengage. See Traction Control/
Electronic Stability Control 0 239. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC
will not engage if the TCS or
StabiliTrak/ESC electronic stability
control system is disabled.
ACC can reduce the need for you to
frequently brake 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
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 this section.
Complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0 209.
Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
On winding and hilly roads or
when the sensors are blocked by
snow, ice, or dirt. The system
DRIVING AND OPERATING
Warning (Continued)
may not detect a vehicle ahead.
Keep the entire front of the
vehicle clean.
Visibility is low, such as in fog,
rain, or snow conditions. ACC
performance is limited under
these conditions.
On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
: Press to turn the system on or
off. The indicator turns white on the
instrument cluster when ACC is
turned on.
