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 Statement0410.
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 0240. 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 0210.
{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
(Continued)
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.
J:Press to turn the system on or
off. The indicator turns white on the
instrument cluster when ACC is
turned on.

The set speed can also be increased
while the vehicle is stopped.
.If stopped with the brake applied,
press RES+ until the desired set
speed is displayed.
.If ACC is holding the vehicle at a
stop and there is another vehicle
directly ahead, pressing RES+ will
increase the set speed.
.Pressing RES+ when there is no
longer a vehicle ahead or the vehicle
ahead is pulling away and the brake
is not applied will cause the ACC to
resume.
When it is determined there is no
vehicle ahead or the vehicle ahead is
beyond the selected following gap,
then the vehicle speed will increase to
the set speed.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster (Base
Level) 094 or
Instrument Cluster (Uplevel) 096. The
increment value used depends on the
units displayed. Reducing Speed While ACC Is at a
Set Speed
If ACC is already activated, do one of
the following:
.Use the brake to get to the desired
lower speed. Release the brake and
press SET−. The vehicle will now
cruise at the lower speed.
.Press and hold SET−
until the
desired lower speed is displayed,
then release it.
.To decrease speed in smaller
increments, press SET− to the first
detent. For each press, the vehicle
goes about 1 km/h (1 mph) slower.
.To decrease speed in larger
increments, press or hold SET− to
the second detent. For each press,
the vehicle speed decreases to the
next 5 km/h (5 mph) mark on the
speedometer.
The set speed can also be decreased
while the vehicle is stopped.
.To decrease speed while the vehicle
is stopped, press SET− until the
desired set speed is displayed. Selecting the Follow Distance Gap
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected.
Press
[on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap setting
displays briefly on the instrument
cluster and the HUD (if equipped).
Subsequent presses cycle the gap
button through three settings: Far,
Medium, or Near. The gap setting will
be maintained until it is changed.
Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the

following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions.
Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. SeeForward Collision Alert
(FCA) System 0285.
Courtesy Gap (If Equipped with
Super Cruise)
Press and Hold
[on the steering
wheel when vehicle is moving to
temporarily increase the gap with the
vehicle ahead to allow for merging
traffic.
Press and Hold
[when stopped to
cancel ACC from resuming
automatically (if the stop is brief) and
remain stationary. This can be used to
allow traffic to merge between you
and the vehicle ahead.
Press RES+ or the accelerator pedal to
resume ACC. Following distance gap
will return to the original selection
after hold. Alerting the Driver
If ACC is engaged, driver action may
be required when ACC cannot apply
sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, the
collision alert symbol will flash on the
windshield. Either eight beeps will
sound from the front, or both sides of
the Safety Alert Seat will pulse five
times. See
“Collision/Detection
Systems” underVehicle Personalization
0 123.
See Defensive Driving 0210. Approaching and Following a
VehicleThe vehicle ahead indicator is in the
instrument cluster and HUD display,
if equipped.
The vehicle ahead indicator only
displays when a vehicle is detected in
your vehicle’s path moving in the
same direction.
If this symbol is not displaying, ACC
will not respond to or brake to
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow a detected vehicle ahead at the
selected follow gap. The vehicle speed
increases or decreases to follow a
detected vehicle in front of your
vehicle when that vehicle is traveling
slower than your vehicle set speed.
It may apply limited braking,
if necessary. When braking is active,

258 DRIVING AND OPERATING
Notification to Resume ACC
ACC will maintain a follow 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. See
“Alert Type”and “Adaptive Cruise Go
Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 123.
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, the ACC
automatically applies the Electric
Parking Brake (EPB) to hold the
vehicle. The EPB status light will turn
on. See Electric Parking Brake 0238.
To release the EPB, press the
accelerator pedal. A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle.
{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.
{Warning
Leaving the vehicle without placing
it in P (Park) can be dangerous. Do
not leave the vehicle while it is
being held at a stop by ACC. Always
place the vehicle in P (Park) and
turn off the ignition before leaving
the vehicle.
ACC Override
If using the accelerator pedal while
ACC is active, the ACC indicator turns
blue on the instrument cluster and in the HUD (if equipped) to indicate that
automatic braking will not occur. ACC
will resume operation when the
accelerator pedal is not being pressed.
{Warning
The ACC will not automatically
apply the brakes if your foot is
resting on the accelerator pedal.
You could crash into a vehicle
ahead of you.
Curves in the Road
{Warning
On curves, ACC may not detect a
vehicle ahead in your lane. You
could be startled if the vehicle
accelerates up to the set speed,
especially when following a vehicle
exiting or entering exit ramps. You
could lose control of the vehicle or
crash. Do not use ACC while driving
on an entrance or exit ramp. Always
be ready to use the brakes if
necessary.

DRIVING AND OPERATING 259
{Warning
On curves, ACC may respond to a
vehicle in another lane, or may not
have time to react to a vehicle in
your lane. You could crash into a
vehicle ahead of you, or lose control
of your vehicle. Give extra attention
in curves and be ready to use the
brakes if necessary. Select an
appropriate speed while driving in
curves.
ACC may operate differently in a
sharp curve. It may reduce the vehicle
speed if the curve is too sharp.
If equipped, the curve speed
control indicator
nmay illuminate
green when ACC is actively controlling
the vehicle speed and detects a sharp
curve on the road ahead.
ACC automatically slows the vehicle
down while navigating the curve and
may increase speed out of the curve,
but will not exceed the set speed.
When following a vehicle and entering
a curve, ACC may not detect the
vehicle ahead and accelerate to the set
speed. When this happens, the vehicle
ahead indicator will not appear.
ACC may detect a vehicle that is not
in your lane and apply the brakes.
ACC may occasionally provide an alert
and/or braking that is considered
unnecessary. It could respond to
vehicles in different lanes, signs, guardrails, and other stationary
objects when entering or exiting a
curve. This is normal operation. The
vehicle does not need service.
Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.
Objects Not Directly in Front of Your
Vehicle
The detection of objects in front of
the vehicle may not be possible if:
.The vehicle or object ahead is not
within your lane.
.The vehicle ahead is shifted, not
centered, or is shifted to one side of
the lane.
