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 0244.
Alerting the Driver

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-13566829) -
2020 - CRC - 6/14/19
216 DRIVING AND OPERATING
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 0140.
See Defensive Driving 0173.
Approaching and Following a
Vehicle
The vehicle ahead indicator is on the
instrument cluster and HUD display.
This indicator only displays when a
vehicle is detected in your vehicle’s
path moving in the same direction. If this indicator 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 the vehicle in front at the
selected follow gap. The vehicle speed
increases or decreases to follow the
vehicle in front of you, but will not
exceed the 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.
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
(Continued)
Warning (Continued)
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.
ACC Automatically Disengages
ACC may automatically disengage and
you will need to manually apply the
brakes to slow the vehicle if:
. The sensors are blocked.
. The Traction Control System (TCS)
or StabiliTrak/ESC system 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.
The ACC indicator 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 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
0 140. 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 0200.
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.
