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when ACC is no longer active.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.

218 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.
{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.
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.
ACC may occasionally provide an alert
and/or braking that is considered
unnecessary. It could respond to

making a lane change:
. Always check mirrors.
. Glance over your shoulder.
. Use the turn signals.
Take Over Alert
{Warning
Super Cruise will not maintain the
vehicle’s speed while the steering
wheel light bar is flashing red.
If the steering wheel light bar
flashes red, immediately resume
manual steering to prevent serious
injury or death. If you do not
resume manual steering, the vehicle
will begin to slow in the same lane
and eventually come to a complete
stop on the freeway. Any time the steering wheel light bar
flashes red, resume manual steering
immediately. The instrument cluster
light
^, will also turn red and a
message will display in the Driver
Information Center (DIC). In addition,
beeps will sound, or the Safety Alert
Seat will vibrate. See “Collision/
Detection Systems” underVehicle
Personalization 0140. After you begin
steering manually, then Super Cruise
will disengage.
The red flashing steering 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

.A Super Cruise system fault
occurs.
Attention to the Road
{Warning
Super Cruise is a driver assistance
system and cannot accurately
detect or predict all situations.
Super Cruise is not a crash
avoidance system. To prevent
serious injury or death, you must
supervise the driving task and
monitor the road conditions. You
may need to respond to traffic
events by steering, braking,
or accelerating. See Defensive
Driving 0173. Super Cruise also
cannot determine whether you are
awake, asleep, impaired, or properly
focused on safe driving. The vehicle
could crash into other vehicles,
drive out of the lane, or drive off
the road. Complete attention is
always required while driving, even
while using Super Cruise. Be
prepared to take over steering or
apply the brakes at any time.
{Warning
To prevent serious injury or death,
be alert and pay special attention
when passing highway exits,
entrances, and crossings with Super
Cruise, and be ready to take control
of the vehicle when necessary.
Changes in lane markings around
exits and entrances can
momentarily cause Super Cruise to
not detect the correct lane. If this
occurs, Super Cruise may attempt
steering inputs to bring the vehicle
back into the correct lane and, in
rare circumstances, could
over-correct and cause the vehicle
to momentarily cross into a lane
next to your vehicle unless you
manually steer to maintain your
lane position. The Driver Attention System (DAS) on
the steering column continually
monitors driver head and eye position
to estimate driver attention to the
road. The camera does not record or
share pictures, audio, or video.
Sunglasses, hats, or other types of
clothing that change the shape of the
head may interfere with camera
performance. To improve camera
performance, raise or lower the
steering wheel, or change the seat
position.
