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:

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.
