210 DRIVING AND OPERATING
When pressed, the current gap setting
displays briefly on the instrument
cluster. 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 0226. 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 on the HUD 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 0135.
See Defensive Driving 0166. 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,

DRIVING AND OPERATING 211
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.
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. Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
.
Vehicles in front of your vehicle
that have a rear aspect that is low,
small, or irregular.
. An empty truck or trailer that has
no cargo in the cargo bed.
. Vehicles with cargo extending
from the back end.
. Non-standard shaped vehicles,
such as vehicle transport, vehicles
with a side car fitted, or horse
carriages.
. Vehicles that are low to the road
surface.
. Objects that are close to the front
of your vehicle.
. Vehicles on which extremely heavy
cargo is loaded in the cargo area
or rear seat.
ACC Automatically Disengages
ACC may automatically disengage and
the driver will need to manually apply
the brakes to slow the vehicle when:
.
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.

212 DRIVING AND OPERATING
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. See
“Alert Type ”and “Adaptive Cruise Go
Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 135. When the vehicle ahead drives away,
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 0198.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0134.
{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) indicating ACC
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.

DRIVING AND OPERATING 213
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.
{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(Continued)
Warning (Continued)
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.
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.

214 DRIVING AND OPERATING
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. Driving in Narrow Lanes
Vehicles in adjacent traffic lanes or
roadside objects may be incorrectly
detected when located along the
roadway.
Do Not Use ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on steep
hills or when towing a trailer. ACC will
not detect a vehicle in the lane while
driving on steep hills. If the brakes are
applied, ACC disengages.
Disengaging ACC
There are three ways to

.
Step lightly on the brake pedal.
. Press
*.
. Press
o.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
ois pressed or if the
ignition is turned off.
Weather Conditions Affecting ACC
If the interior temperature is
extremely high, the instrument cluster
may indicate that ACC is temporarily
unavailable. This can be caused by
extreme hot weather conditions with
direct sunlight on the front camera.
ACC will return to normal operation
once the cabin temperature is lower.

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-12984300) -
2020 - CRC - 3/19/19
DRIVING AND OPERATING 215
Conditions that are associated with
low visibility, such as fog, rain, snow,
or road spray, may limit ACC
performance. Water droplets from rain
or snow that remain on the
windshield may also limit ACC’s
ability to detect objects.
Lighting Conditions Affecting ACC
The ACC front camera can be affected
by poor lighting conditions, and ACC
may have limited performance when:
.There are changes in brightness,
such as entering and exiting
tunnels, bridges, and overpasses.
. Low sun angles cause the camera
to not detect objects, or it is more
difficult to detect objects in the
same traffic lane.
. Lighting is poor in the evening or
early morning .
There are multiple changes in
brightness or shadows along the
vehicle roadway.
. In a tunnel without the headlamps
on, or in a tunnel when there is a
vehicle in front that does not have
its taillamps on.
. Subjected to strong light from
opposing lane traffic in the front
of the vehicle, such as high-beam
headlamps from oncoming traffic.
Accessory Installations and Vehicle
Modifications
Do not install or place any object
around the front camera windshield
area that would obstruct the front
camera view.
Do not install objects on top of the
vehicle that overhang and obstruct the
front camera, such as a canoe, kayak,
or other items that can be transported
on the vehicle roof.
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 can
become blocked by snow, ice, dirt,
mud, or debris. This area needs to be
cleaned for ACC to operate properly.
The vehicle headlamps may need to
be cleaned due to dirt, snow, or ice.
Objects that are not illuminated
correctly may be difficult to detect.
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 0324.
