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.
See Radio Frequency
Statement0452.
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 0271. 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 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 (Continued)
Warning (Continued)
and you should be ready to
take action and apply the
brakes. See Defensive
Driving0235.
{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 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

.The sensors are blocked.
.The Traction Control System
(TCS) or StabiliTrak/ESC has
activated or been disabled.
.There is a fault in the
system.
.The radar falsely reports
blockage when driving in a
desert or remote area with
no other vehicles or
roadside objects.
.A DIC message may display
to indicate that ACC is
temporarily unavailable.
The ACC active symbol will
turn white when ACC is no
longer active.
In some cases, when ACC will
not activate, regular cruise
control may be used. See
“Switching Between ACC and
Regular Cruise Control”
previously in this section.
Always consider driving
conditions before using either
cruise control system. Notification to Resume ACC
ACC will maintain a following
gap behind a detected vehicle
and slow your vehicle to a
stop behind that vehicle.
If the stopped vehicle ahead
has driven away and ACC has
not resumed, the vehicle
ahead indicator will flash as a
reminder to check traffic
ahead before proceeding. In
addition, the left and right
sides of the Safety Alert Seat
will pulse three times, or three
beeps will sound. Touch the
Settings icon on the
infotainment home page.
Select
“Vehicle” to display the
list of available options and
select ”Alert Type” and
“Adaptive Cruise Go Notifier”
in “Collision/Detection
Systems”.
When the vehicle ahead drives
away, ACC resumes
automatically if the stop was
brief. If necessary, press RES+
or the accelerator pedal to
resume ACC. If stopped for more than two minutes or if
the driver door is opened and
the driver seat belt is
unbuckled, ACC automatically
applies the Electric Parking
Brake (EPB) to hold the
vehicle. The Electric Parking
Brake light will turn on. See
Electric Parking Brake
0269.
To release the EPB, press the
accelerator pedal.
A DIC warning message may
display indicating to shift to
P (Park) before exiting the
vehicle. See Vehicle Messages
0 146.
{Warning
If ACC has stopped the
vehicle, and if ACC is
disengaged, turned off,
or canceled, the vehicle will
no longer be held at a stop.
The vehicle can move. When
ACC is holding the vehicle at
a stop, always be prepared
to manually apply the
brakes.
