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 (Continued)

Warning (Continued)
the road conditions. You
may need to respond to
traffic events by steering,
braking, or accelerating. See
Defensive Driving0235.
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:

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.
