or the apply the accelerator pedal. Alerting the Driver
If ACC is engaged, driver action may be
required when ACC cannot apply sufficient
braking because your vehicle is approaching
a vehicle ahead too quickly.
When this condition occurs, the red collision
alert symbol 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. To view available settings
from the infotainment screen, touch Settings
> Vehicle > Collision/Detection Systems.
See
Defensive Driving 0183.
Approaching and Following a Vehicle
The vehicle ahead indicator light is displayed
in the instrument cluster and the HUD,
if equipped. It only displays when a vehicle
is detected in your vehicle’s path and is
moving in the same direction. If the vehicle
ahead indicator light does not appear in the
instrument cluster, then ACC will not
respond to, or brake for, vehicles ahead.
While ACC is active, ACC will automatically
adjust your vehicle’s speed to follow a
detected vehicle ahead according to the
selected following gap setting. ACC may
decrease your vehicle’s cruise speed when
following a detected vehicle ahead that is
traveling slower than your ACC set speed.
ACC may apply limited braking, if necessary.
When ACC automatic braking is active, the
brake lamps will turn 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
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.
Pay close attention to the road ahead to
avoid these three increasing alerts:
