266 DRIVING AND OPERATING
{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:

Map Updates
Super Cruise map information must
be periodically updated at least once
every seven months to determine
whether Super Cruise is available on
certain roads. See the following
website for Super Cruise map open
source compliance documentation,
including the license information:
http://oss.veoneer.com/
Data Download
If the vehicle is equipped with OnStar
and has an active service plan,
additional data may be collected
through the OnStar system. This
includes information about: the
vehicle’s operation; a crash involving
the vehicle; the use of the vehicle and
its features; and, in certain situations,
the location and approximate GPS
speed of the vehicle. Refer to the
OnStar Terms and Conditions and
Privacy Statement on the OnStar
website.Location Services
This setting enables or disables
sharing of vehicle location outside the
vehicle for certain purposes. Even if
the Location Services setting is
disabled, vehicle location information
will continue to be shared for
emergency services and Super Cruise,
if equipped.
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.

with the proper training, tools, and
safety instructions, which your
dealer has. Without proper training
and tools the vehicle may become
damaged.

When an object is very close to the
vehicle rear (<0.6m (2 ft)), five beeps
will sound from the rear followed by a
continuous beep from the rear,
or both sides of the Safety Alert Seat
will pulse five times. When an object
is very close to the vehicle front
(<0.3m (1 ft)), a continuous beep will
sound from the front, or both sides of
the Safety Alert Seat will pulse five
times. Beeps for FPA are higher
pitched than for RPA.
When the System Does Not Seem to
Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST :If this
message occurs, check the following
conditions:
.The sensors are not clean. Keep the
vehicle's rear bumper free of mud,
dirt, snow, ice, and slush. For
cleaning instructions, see Exterior
Care 0370.
.The Park Assist sensors are covered
by frost or ice. Frost or ice can form
around and behind the sensors and
may not always be seen; this can
occur after washing the vehicle in cold weather. The message may not
clear until the frost or ice has
melted.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system.
PARK ASSIST OFF : If the PA system
does not activate due to a temporary
condition, the message displays on the
DIC. This can occur under the
following conditions:
.The driver has disabled the system.
.An object was hanging out of the
trunk during the last drive cycle.
Once the object is removed, RPA
will return to normal operation.
.The bumper is damaged. Take the
vehicle to your dealer to repair the
system.
.Other conditions, such as vibrations
from a jackhammer or the
compression of air brakes on a very
large truck, are affecting system
performance. Backing Warning and Reverse
Automatic Braking
Vehicles with Adaptive Cruise Control
(ACC) have the Backing Warning
System and Reverse Automatic
Braking (RAB) system. The Backing
Warning part of this system can warn
of rear objects when backing up at
speeds greater than 8 km/h (5 mph),
and RAB may automatically brake
hard at speeds between 1–32 km/h
(0.5–20 mph).
The Backing Warning System will
beep once from the rear when an
object is first detected, or pulse twice
on both sides of the Safety Alert Seat.
When the system detects a potential
crash, beeps will be heard from the
rear, or five pulses will be felt on both
sides of the Safety Alert Seat. There
may also be a brief, sharp application
of the brakes.
{Warning
The Backing Warning System only
operates at speeds greater than
8 km/h (5 mph). It does not detect
children, pedestrians, bicyclists,
