Adaptive Cruise
Control (Advanced)
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.
See Radio Frequency
Statement0477.
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
0276. 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 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

Warning (Continued)
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 0240.
{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

when cruise is not being used.
Select the set speed desired
for ACC. This is the vehicle
speed when no vehicle is
detected in its path.
While the vehicle is moving,
ACC will not set at a speed
below a minimum speed,
although it can be resumed.
If equipped with Super Cruise,
this minimum speed is 5 km/h
(3 mph), otherwise, it is

2. Get up to the desired speed.
3. Press and release SET–.
4. Remove your foot from the accelerator pedal.
After ACC is set, it may
immediately apply the brakes if
a vehicle ahead is detected
closer than the selected
following gap.
ACC can also be set while the
vehicle is stopped if ACC is on
and the brake pedal is applied.
The ACC indicator displays on
the instrument cluster and
Head-Up Display (HUD),
if equipped. When ACC is
turned on, the indicator will be
lit white. When ACC is
engaged, the indicator will turn
green. Be mindful of speed limits,
surrounding traffic speeds,
and weather conditions when
selecting the set speed.
Resuming a Set Speed
If the ACC is set at a desired
speed and then the brakes are

The vehicle ahead indicator is
in the instrument cluster and
HUD display (if equipped).
It 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 for
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, the
brake lamps will come on. The
automatic braking may feel or
sound different than if the
brakes were applied manually.
This is normal.Passing a Vehicle While
Using ACC
If the set speed is high
enough, and the left turn
signal is used to pass a vehicle
ahead in the selected
following gap, ACC may assist
by gradually accelerating the
vehicle prior to the lane
change.
{Warning
When using ACC to pass a
vehicle or perform a lane
change, the following
distance to the vehicle being
passed may be reduced.
ACC may not apply
sufficient acceleration or
braking when passing a
vehicle or performing a lane
change. Always be ready to
manually accelerate or brake
to complete the pass or lane
change.
Stationary or Very
Slow-Moving Objects
{Warning
ACC may not detect and
react to stopped or
slow-moving vehicles ahead
of you. For example, the
system may not brake for a
vehicle it has never detected
moving. This can occur in
stop-and-go traffic or when
a vehicle suddenly appears
due to a vehicle ahead
changing lanes. Your vehicle
may not stop and could
cause a crash. Use caution
when using ACC. Your
complete attention is always
required while driving and
you should be ready to take
action and apply the brakes.

292 Driving and Operating
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.

could crash into a vehicle
ahead of you, or lose control(Continued)
Warning (Continued)
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
bmay
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.
