220 DRIVING AND OPERATING
Super Cruise
If equipped, Super Cruise can steer to
maintain lane position under certain
conditions on compatible highways
that are separated from opposing
traffic.
{Warning
Super Cruise can only assist to
maintain lane position when driving
on compatible highways. You must
supervise the driving task and
monitor the freeway conditions.
You may need to respond to traffic
events by steering, braking,
or accelerating. SeeDefensive
Driving 0173.
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
highways 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 Control (ACC), which controls
acceleration and braking while Super
Cruise is enabled and operating.
Review and understand both this
section and the ACC section before
using Super Cruise. See Adaptive
Cruise Control 0211.
An active OnStar or connected service
plan that includes Emergency Services
is required to use Super Cruise.
{Warning
Super Cruise does not perform all
aspects of driving, nor does it do
everything a driver can do. Super
Cruise only steers to maintain lane
position. Super Cruise can only be
used with Adaptive Cruise Control.
Super Cruise does: . Not prevent crashes or warn
of possible crashes.
. Not steer to avoid stopped or
slow-moving vehicles,
construction barriers or
cones, motorcycles, children,
pedestrians, animals, or other
objects on the freeway.
. Not steer in response to
vehicles or objects next to
your vehicle, including
vehicles attempting to enter
your lane.
. Not change lanes.
. Not steer to merge onto or to
exit freeways.

224 DRIVING AND OPERATING
Steering Manually and Changing
Lanes
The vehicle can always be manually
steered, even with Super Cruise
engaged; for example, when changing
lanes.
When the steering wheel is moved
manually, the steering wheel light bar
pulses blue and
^on the instrument
cluster turns blue to indicate Super
Cruise is not steering the vehicle.
When ready to allow Super Cruise to
resume steering again, position the
vehicle in the center of the lane, hold
the steering wheel until the steering
wheel light bar turns green, and then
release the steering wheel when it is
safe to do so.
Super Cruise does not respond to
vehicles in other lanes near your
vehicle.
{Warning
To help prevent crashes before
making a lane change:
. Always check mirrors.
. Glance over your shoulder.
. Use the turn signals.
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 freeway. 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 display in the Driver
Information Center (DIC). In addition,
beeps will sound, or the Safety Alert
Seat will vibrate. See “Collision/
Detection Systems” underVehicle
Personalization 0140. 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 freeway.
. 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 freeway ends.

.A Super Cruise system fault
occurs.
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. See Defensive
Driving 0173. 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.

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
