212 Driving and Operating
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

begin to slow in the same lane and
eventually come to a complete stop on
the road.
Any time the steering wheel light bar
flashes red, resume manual steering
immediately.
To begin steering manually, hold the
steering wheel firmly (with both hands)
using the highlighted regions as shown in
the picture below.
The Super Cruise lightZwill also turn red

Safety Alert Seat will vibrate. To view
available settings from the infotainment
home screen, touch Settings > Vehicle >
Collision/Detection Systems. 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 road speed limit of the Super
Cruise-compatible, non-divided road is
below 72 km/h (45 mph).
.The Super Cruise-compatible road ends.
.The vehicle is approaching an intersection
controlled by a traffic light, stop sign,
or other traffic control device.
.A Super Cruise system fault occurs.
.Super Cruise is unable to complete the
lane change maneuver.
.Super Cruise detects the outside air
temperature is very cold.
The steering wheel light bar may flash
amber if the system anticipates certain
conditions that may require the driver to
take steering control. The Super Cruise light
Zwill also turn amber in the instrument
cluster, and a message will display in the
DIC. When the steering wheel light bar
flashes amber, resume manual steering to
prevent further escalation.

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
0 164. 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.

214 Driving and Operating
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. To view available settings from the infotainment home screen, touch Settings >
Vehicle > Collision/Detection Systems.
.Take over steering, then Super Cruise may disengage or the steering wheel light bar will flash blue to
indicate the need for a driver override. Do not take hands off the steering wheel until the steering
wheel light bar is green.
.To re-engage Super Cruise after disengagement, pressZon the steering wheel. See “Using Super
Cruise” previously in this section.
Third Alert
.If the steering wheel light bar flashes red for too long, a voice command will tell you to take control of
the vehicle.
.Take control of the steering immediately; ACC and Super Cruise will disengage.
.A DIC message will indicate that Super Cruise is locked out. Super Cruise cannot be re-engaged until the
vehicle is turned off and back on.
.Continued failure to take over steering will cause the vehicle to brake to a stop and OnStar will be
called. The brake lamps and hazard warning flashers will come on.
.Take control of the vehicle and continue driving.

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. You
may not have time to react to a vehicle (Continued)
Warning (Continued)
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.
