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:

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 in the lane next to
your vehicle while on curves
in the road.
Super Cruise may operate
differently in sharp curves.
The vehicle 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.

System Care
The camera on the steering
column has a lens cover that
may become dirty over time
and affect camera
performance. Clean the lens
cover with a soft cloth
sprayed with glass cleaner.
Wipe the lens gently, then dry
it. Never use abrasive cloths/
cleaners or corrosive
chemicals of any kind on the
lens cover.
Super Cruise uses the front
radar, front camera, and
360-degree cameras for its
operation. Clean surfaces are
required for Super Cruise
operation. See Adaptive
Cruise Control (Advanced)
0304, “Surround Vision
Camera” under Assistance
Systems for Parking or
Backing 0335, and Lane Keep
Assist (LKA) 0351 for care

The Super Cruise system is
a highly sophisticated
system and should only be
serviced by technicians with
the proper training, tools,
and safety instructions,
which your dealer has.
Without proper training and
tools the vehicle may
become damaged.
