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.
If equipped with Super Cruise, the radar
sensors on the front of the vehicle can also
become blocked by snow, ice, dirt, mud,
or debris. These areas need 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” underExterior Care 0414.Super Cruise
If equipped, Super Cruise can steer to
maintain lane position under certain
conditions on Super Cruise-enabled roads
that are separated from opposing traffic.
Super Cruise can also steer to perform a
lane change under certain conditions on
Super Cruise-enabled roads. when a lane
change is initiated by the driver using the
turn signal lever.
A lane change can be initiated by the driver
using the turn signal lever.
The Super Cruise System may initiate a lane
change maneuver in following scenarios:
.to pass slower traffic
.when the current lane is ending ahead
.to return to the initial lane
See “Super Cruise Lane Change” later in this
section and Turn and Lane-Change Signals
0 149.
{Warning
Super Cruise can only assist to maintain
lane position, or steer to change lanes,
when driving on compatible roads. 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.
Super Cruise is:
.Not a self-driving system
.Not a crash avoidance or warning
system
.Not a substitute for proper supervision
of the driving task.
Super Cruise uses the following to detect
the current lane position and lane markings
ahead on compatible roads under certain
conditions:
.Cameras
.Global Positioning System (GPS) sensing
.A high-precision map
.GPS-enhancement data downloaded
through OnStar
Super Cruise works with Adaptive Cruise

{Warning
Super Cruise Lane Change may not detect
a vehicle in an adjacent lane. Always
supervise the driving task and monitor
traffic conditions when using the Super
Cruise Lane Change feature. Only request
a lane change when traffic conditions are
safe for a lane change, and always be
ready to manually steer the vehicle. See
“Steering Manually and Changing Lanes”
listed previously in this section.
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 road. To begin steering manually, hold the
steering wheel firmly (with both hands)
using the highlighted regions as shown in
the picture below.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

(DIC). In addition, beeps will sound, or the
Safety Alert Seat will vibrate. See “Collision/
Detection Systems” underVehicle
Personalization 0137. 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 toward the road.
.ACC is canceled.
.The vehicle is on a tight curve, or the
lanes are too wide, or the vehicle goes
into a curve too fast.
.The compatible road ends.

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. SeeDefensive Driving
0 206. 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.
Pay close attention to the road ahead to
avoid these three increasing alerts:

First Alert
.If the steering wheel light bar flashes green, the system has detected that your head and eyes may not be
directed toward the road.
.The flashing will stop when the system detects that your head and eyes appear to be directed toward
the road.
Second Alert
.If the steering wheel light bar flashes green for too long, Super Cruise will alert the driver to take control of
steering immediately by flashing the light bar red. Also, either beeps will sound or the Safety Alert Seat will
vibrate. See “Collision/Detection Systems” underVehicle Personalization 0137.
.Take over steering, then Super Cruise will disengage.

Driving and Operating 275
Stationary or Very Slow-Moving Objects;
Cross-Traffic
{Warning
Super Cruise is not a crash avoidance
system and will not steer or brake to
avoid a crash. Super Cruise does not steer
to prevent a crash with stopped or
slow-moving vehicles. You must supervise
the driving task and may need to steer
and brake to prevent a crash, especially
in stop-and-go traffic or when a vehicle
suddenly enters your lane. Always pay
attention when using Super Cruise.
Failure to do so could result in a crash
involving serious injury or death.
Curves in the Road
{Warning
The vehicle could drift out of your lane of
travel. To prevent crashes, always be
ready to manually steer.
Super Cruise may not detect your lane on
curves in the road. Super Cruise may not
detect the markings that show your lane. (Continued)
Warning (Continued)
You may not have time to react to a
vehicle in the lane next to your vehicle
while on curves in the road.
Super Cruise may hand control back to the
driver more often driving around a sharp
curve while towing a trailer.
Super Cruise may operate differently in
sharp curves. It may drift out of your lane
of travel if the curve is too sharp.
When entering a curve, Super Cruise may
not detect the lane markings and may not
adjust the steering enough to stay in your
lane of travel. When this happens, you will
need to steer the vehicle.
Super Cruise may detect other lane
markings that are not in your lane and may
or may not steer appropriately to maintain
your lane.
Super Cruise may occasionally provide an
alert and/or steering that is considered
unnecessary. It could respond to lane
markings 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.
