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 Control0291. 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 0242.
{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 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.
.When towing a trailer.

Near Gap Setting
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. See Forward Collision
Alert (FCA) System
0346.

312 Driving and Operating
Approaching and Following a
Vehicle
The 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 yourvehicle 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

Warning (Continued)
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 (Continued)

attention is on the road ahead,
ACC resumes automatically.
See“Attention to the Road”
under Super Cruise 0317.
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 0288.
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

Warning (Continued)
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 (Continued)

entrance or exit ramp.
Always be ready to use the
brakes if necessary.
{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.

Driving and Operating 317
Do not modify the hood,
headlamps, or fog lamps, as
this may limit the camera’s
ability to detect an object.
Cleaning the Sensing System
The camera sensor on the
windshield behind the
rearview mirror and the radar
sensors on the front of the
vehicle can become blocked by
snow, ice, dirt, or mud. These
areas need to be cleaned for
ACC to operate properly.
If ACC will not operate, regular
Cruise Control may be
available. See“Switching
Between ACC and Regular
Cruise Control” previously in
this section. Always consider
driving conditions before using
either cruise control system.
For cleaning instructions, see
“Washing the Vehicle” under
Exterior Care 0457.Super Cruise
