When ACC is engaged, a
green
oindicator will be lit on
the instrument cluster. When
the regular cruise control is
engaged, a green
Jindicator
will be lit on the instrument
cluster and the following gap
will not display.
When the vehicle is turned on,
the cruise control mode will be
set to the last mode used
before the vehicle was
turned off.
{Warning
Always check the cruise
control indicator on the
instrument cluster to
determine which mode
cruise control is in before
using the feature. If ACC is
not active, the vehicle will
not automatically brake for
other vehicles, which could
cause a crash if the brakes
are not applied manually.
You and others could be
seriously injured or killed. Setting Adaptive Cruise
Control
If
ois on when not in use,
SET-/RES+ could be pressed
by mistake and activate ACC
when not desired. Keep
ooff
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
25 km/h (15 mph). The minimum
allowable set speed is 25 km/h
(15 mph).
To set ACC while moving:
1. Press
J.
2. Get up to the desired speed.
3. Press and release SET−. 4. Remove your foot from the
accelerator.
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 ACC is set at a desired
speed and then the brakes are
applied, ACC is disengaged
without erasing the set speed
from memory.

the first detent. For each
press, the vehicle goes
1 km/h (1 mph) faster.
.To increase speed in larger
increments, press RES+ to
the second detent. For each
press, the vehicle speed increases to the next 5 km/h
(5 mph) mark on the
speedometer.
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.

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.

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

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 0316.
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 0287.
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 (Continued)

hands can be taken off the
steering wheel.
Always pay attention to the
road and the operation of the
vehicle. Always monitor and be
attentive of surrounding
traffic, including vehicles that
may cross the road in front of
your vehicle. Super Cruise steering can be
overridden with manual
steering at any time. When
Super Cruise is engaged,
always be prepared to take
immediate action
—including
steering, accelerating, and
braking quickly, if necessary.
When Super Cruise is
engaged, the Forward
Collision System will alert and
brake.
Steering Manually and
Changing Lanes
The vehicle can always be
manually steered, even with
Super Cruise engaged; for
example, when manually
changing lanes.
When the steering wheel is
moved manually, the steering
wheel light bar flashes blue

wheel light bar could occur
under any of the following
conditions:
.Lane markings are poor,
or visibility is limited.
.The Driver Attention System
(DAS) does not detect that
the driver's head and eyes
are directed toward
the road.
.ACC is canceled.
.The vehicle is on a tight
