entrance or exit ramp.
Always be ready to use the
brakes if necessary.
{Warning
On curves, ACC may
respond to a vehicle in
another lane, or may not
have time to react to a
vehicle in your lane. You
could crash into a vehicle
ahead of you, or lose control
of your vehicle. Give extra
attention in curves and be
ready to use the brakes if
necessary. Select an
appropriate speed while
driving in curves.
ACC may operate differently
in a sharp curve. It may reduce
the vehicle speed if the curve
is too sharp. If equipped, the curve speed
control indicator
nmay
illuminate green when ACC is
actively controlling the vehicle
speed and detects a sharp
curve on the road ahead.
ACC automatically slows the
vehicle down while navigating
the curve and may increase
speed out of the curve, but will
not exceed the set speed.
When following a vehicle and
entering a curve, ACC may not
detect the vehicle ahead and
accelerate to the set speed.
When this happens, the
vehicle ahead indicator will not
appear.
ACC may detect a vehicle that
is not in your lane and apply
the brakes.
ACC may occasionally provide
an alert and/or braking that is
considered unnecessary.
It could respond to vehicles 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.

316 Driving and Operating
Do not modify the hood,
headlamps, or fog lamps, as
this may limit the camera’s
ability to detect an object.
Cleaning the Sensing System
The camera sensor on the
windshield behind the
rearview mirror and the radar
sensors on the front of the
vehicle can become blocked by
snow, ice, dirt, or mud. These
areas need to be cleaned for
ACC to operate properly.
If ACC will not operate, regular
Cruise Control may be
available. See“Switching
Between ACC and Regular
Cruise Control” previously in
this section. Always consider
driving conditions before using
either cruise control system.
For cleaning instructions, see
“Washing the Vehicle” under
Exterior Care 0455.Super Cruise
If equipped, Super Cruise can
steer to maintain lane position
under certain conditions on
Super Cruise-enabled roads
that are separated from
opposing traffic.
Super Cruise can also steer to
perform a lane change under
certain conditions on Super
Cruise-enabled roads.
A lane change can be initiated
by the driver using the turn
signal lever. If equipped with
Automatic Lane Change, the
Super Cruise System may
initiate a lane change
maneuver in the following
scenarios:
.To pass slower traffic
.When the current lane is
ending ahead
.To return to the initial lane See
“Super Cruise Lane
Change” later in this section
and Turn and Lane-Change

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.

How the System Works
The instrument cluster may
have a Park Assist display with
bars that show“distance to
object,” driving direction, and
object location information for
the Park Assist system. As the
object gets closer, more bars
light up and the bars change
color from yellow to amber
to red.
Beeps sound to warn the
driver of certain objects that
are detected around the
vehicle. The frequency of
beeps increases as the vehicle
gets closer to the object.
When the object is very close
to the vehicle, the beeps are
continuous. Beeps for the
front are higher pitched than
beeps for the rear. If equipped
with Safety Alert seat, both
sides of the seat will pulse
alongside the beeps. 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
0455.
.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
appropriate message displays
on the DIC. PA OFF message
is displayed when disabled by
the driver. Front/Rear PA OFF
message is displayed when an
attached object is detected in
the front or rear respectively.
PA Temporarily Unavailable
message is displayed for
system failures. 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

.Clean the headlamps.
Automatic Emergency
Braking (AEB)
If equipped, the AEB system
may help avoid or reduce the
harm caused by front-end
crashes. AEB also includes
Intelligent Brake Assist (IBA).
When the system detects a
vehicle in the path ahead that
is traveling in the same
direction, and that you may
crash into, it can provide a
boost to braking,
or automatically brake the
vehicle. This can help avoid or
lessen the severity of crashes
when driving in a forward gear.
Depending on the situation,
the vehicle may automatically
brake moderately or hard. This
Automatic Emergency Braking
can only occur if a vehicle is
detected. Vehicle detection is
shown by the Forward
Collision Alert (FCA) vehicle
ahead indicator being lit. See
Forward Collision Alert (FCA)
System0342. The system works when
driving in a forward gear
between 8 km/h (5 mph) and
80 km/h (50 mph), or on
vehicles with Adaptive Cruise
Control (ACC), above 4 km/h
(2 mph). It can detect vehicles
up to approximately 60 m
(197 ft).
{Warning
AEB is an emergency crash
preparation feature and is
not designed to avoid
crashes. Do not rely on AEB
to brake the vehicle. AEB will
not brake outside of its
operating speed range and
only responds to detected
vehicles.
AEB may not:
.Detect a vehicle ahead on
winding or hilly roads.
.Detect all vehicles,
especially vehicles with a
trailer, tractors, muddy
vehicles, etc.
(Continued)
Warning (Continued)
.Detect a vehicle when
weather limits visibility,
such as in fog, rain,
or snow.
.Detect a vehicle ahead if it
is partially blocked by
pedestrians or other
objects.
Complete attention is
always required while
driving, and you should be
ready to take action and
apply the brakes and/or
steer the vehicle to avoid
crashes.
AEB may slow the vehicle to a
complete stop to try to avoid a
potential crash. If this
happens, AEB may engage the
Electric Parking Brake (EPB)
to hold the vehicle at a stop.
Release the EPB or firmly
press the accelerator pedal.
