@:Press to turn on recirculation.
An indicator light comes on. Air is
recirculated to quickly cool the inside
of the vehicle or to reduce the entry of
outside air and odors.
Auto Defog : The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high
humidity is detected, the climate
control system may adjust to outside
air supply and turn on the air
conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control system
does not detect possible window
fogging, it returns to normal
operation.
Ionizer : If equipped with an ionizer,
this feature helps to clean the air
inside the vehicle and remove
contaminants such as pollen, odors,
and dust. If the climate control
system is on and the ionizer is
enabled, the ionizer status indicator
will be lit on the climate control
display.Rear Window Defogger
K: Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.
The defogger can be turned off by
turning the ignition to off or

The rear window defogger can be set
to automatic operation. When auto
rear defog is selected, the rear window
defogger turns on automatically when
the interior temperature is cold and
the outside temperature is about 7 °C
(44 °F) and below. The auto rear
defogger turns off automatically.
If equipped, the heated outside
mirrors turn on when the rear window
defogger button is on and help to
clear fog or frost from the surface of
the mirror. See Heated Mirrors029.
Caution
Do not try to clear frost or other
material from the inside of the
front windshield and rear window
with a razor blade or anything else
that is sharp. This may damage the
rear window defogger grid and
affect the radio's ability to pick up
stations clearly. The repairs would
not be covered by the vehicle
warranty.
Remote Start Climate Control
Operation : If equipped with remote
start, the climate control system may
run when the vehicle is started
remotely. If equipped with heated or
ventilated seats or a heated steering
wheel, these features may come on
during a remote start. See Remote
Vehicle Start 014, Heated and
Ventilated Front Seats 044, and Heated

Sensor
The solar sensor, on top of the
instrument panel near the windshield,
monitors the solar intensity.
The climate control system uses the
sensor information to adjust the
temperature, fan speed, recirculation,
and air delivery mode for best
comfort.
If the sensor is covered, the automatic
climate control system may not work
properly.Afterblow Feature
If equipped, under certain conditions,
the fan may stay on or may turn on
and off several times after you turn
off and lock the vehicle. This is
normal.
Air Vents
Adjustable air vents are in the center
and on the sides of the instrument
panel, and on the rear of the center
console storage.
Move the slider knobs to change the
direction of or to close off the airf low.Operation Tips
.Clear away any ice, snow, or leaves
from air inlets at the base of the
windshield that could block the
flow of air into the vehicle.
.Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle.
.Keep the path under the front seats
clear of objects to help circulate the
air inside of the vehicle more
effectively.
.Use of non-GM approved hood
deflectors can adversely affect the
performance of the system. Check
with your dealer before adding
equipment to the outside of the
vehicle.
.Do not attach any devices to the air
vent slats. This restricts airf low and
may cause damage to the air vents.

DRIVING AND OPERATING 241
Ending Cruise Control
There are four ways to end cruise
control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to
N (Neutral).
.PressJ.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if the
ignition is turned off.
Adaptive Cruise Control
(Advanced)
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed and
following gap. Read this entire section
before using this system. The
following gap is the following time
between your vehicle and a vehicle
detected directly ahead in your path,
moving in the same direction. If no
vehicle is detected in your path, ACC works like regular cruise control. ACC
uses camera and radar sensors. See
Radio Frequency Statement
0393.
If a vehicle is detected in your path,
ACC can apply acceleration or limited,
moderate braking to maintain the
selected following gap. To disengage
ACC, apply the brake. If ACC is
controlling your vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates, the ACC may
automatically disengage. See Traction
Control/Electronic Stability Control
0 235. When road conditions allow
ACC to be safely used, the ACC can be
turned back on.
Disabling the TCS or StabiliTrak/ESC
system will disengage and prevent
engagement of ACC.
ACC can reduce the need for you to
frequently brake and accelerate,
especially when used on expressways,
freeways, and interstate highways.
When used on other roads, you may
need to take over the control of
braking or acceleration more often. 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.
{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver”
in this section.
Complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0205.

Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
.Vehicles with cargo extending from
the back end.
.Non-standard shaped vehicles, such
as vehicle transport, vehicles with a
side car fitted, or horse carriages.
.Objects that are close to the front of
your vehicle.
ACC Automatically Disengages
ACC may automatically disengage and
the driver will need to manually apply
the brakes to slow the vehicle when:
.The sensors are blocked.
.The Traction Control System (TCS)
or StabiliTrak/ESC system has
activated or been disabled.
.There is a fault in the system.
.The radar falsely reports blockage
when driving in a desert or remote
area with no other vehicles or
roadside objects. A DIC message
may display to indicate that ACC is
temporarily unavailable. The ACC indicator will turn white
when ACC is no longer active.
In some cases, when ACC is
temporarily unavailable, regular cruise
control may be used. See
“Switching
Between ACC and Regular Cruise
Control ”in this section. Always
consider driving conditions before
using either cruise control system.
Notification to Resume ACC
ACC will maintain a follow gap behind
a detected vehicle and slow your
vehicle to a stop behind that vehicle.
If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead indicator
will flash as a reminder to check
traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat will pulse three
times, or three beeps will sound. See
”Alert Type ”and “Adaptive Cruise Go
Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 121. When the vehicle ahead drives away,
ACC resumes automatically if the stop
was brief. If necessary, press RES+ or
the accelerator pedal to resume ACC.
If stopped for more than two minutes
or if the driver door is opened and the
driver seat belt is unbuckled, the ACC
automatically applies the Electric
Parking Brake (EPB) to hold the
vehicle. The EPB status light will turn
on. See
Electric Parking Brake 0233.
To release the EPB, press the
accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0120.
{Warning
If ACC has stopped the vehicle, and
if ACC is disengaged, turned off,
or canceled, the vehicle will no
longer be held at a stop. The vehicle
can move. When ACC is holding the
vehicle at a stop, always be
prepared to manually apply the
brakes.

Under certain conditions, the Park
Assist system can assist the driver
during backing and parking
maneuvers when the vehicle is driven
at no more than 9 km/h (6 mph). An
illuminated indicator in the Park
Assist button indicates the system is
ready.
Sensors located in the bumpers
measure the distance between the
vehicle and objects using sonar
technology. These sensors are
designed to detect certain objects up
to 2.5 m (8 ft) behind and 1.2 m (4 ft)
in front of your vehicle that are taller
than 25 cm (10 in).
Different environmental conditions
may affect whether and how far the
Park Assist system can detect objects.
Keep the sensors clean of mud, dirt,
snow, ice, and slush; and clean
sensors after a car wash in freezing
temperatures. Sensors that are not
clean may not detect objects or may
cause the system to alert when not
required.

15440907) - 2022 - CRC - 1/4/22
DRIVING AND OPERATING 255
{Warning
The Park Assist System is no
substitute for careful and attentive
driving. The Park Assist system
does not detect children,
pedestrians, bicyclists, animals,
or objects located below the
bumper or that are too close or too
far from the vehicle. It is not
available at speeds greater than
9 km/h (6 mph). To prevent injury,
death, or vehicle damage, even with
Park Assist, always check the area
around the vehicle and check all
mirrors before moving forward or
backing.
How the System Works
The vehicle may have a Park
Assist amphitheatre-like display on
the cluster with bars that represent
the estimated location of a detected
object and the vehicle’s distance from
the object. As a detected object
becomes closer, more bars light up
and change color from yellow to
amber to red. When an object is first detected in the
rear, one beep will be heard from the
rear, or the driver's seat will pulse two
times, if equipped with Safety Alert
Seat. When an object is very close,
five beeps will sound from the front or
rear (depending on the object's
location), or the driver's seat will pulse
five times. Beeps for front are higher
pitched than the rear.
Turning the System On and Off
The Park Assist System can be turned
on or off using the infotainment
system. See
Vehicle Personalization
0 121.
The
Xbutton is used to turn on or
off the Park Assist, which also turns
on or off the Backing Warning and
Reverse Automatic Braking (RAB) at the same time. When the system is
turned off, a system off message is
shown on the display. This message
disappears after a short period
of time.
Turn off Park Assist when towing a
trailer to prevent unwanted beeps and
when a bike rack is attached to ensure
proper operation.
When the System Does Not Seem to
Work Properly
If a service message displays, check
the following conditions:
.The sensors may not be clean. Keep
the vehicle's front and rear bumpers
free of mud, dirt, snow, ice, and
slush. For cleaning instructions, see
Exterior Care
0357.
.The Park Assist sensors may be
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.

256 DRIVING AND OPERATING
If a service message displays and the
above conditions do not exist, take the
vehicle to your dealer for repairs.
If the Park Assist System does not
activate due to a temporary condition,
a system off message is shown on the
display. This can occur under the
following conditions:
.The driver has disabled the system.
.An object is currently blocking the
rear sensors (for example, bike rack,
tailgate, trailer hitch, etc.). Once the
object is removed, Park Assist will
return to normal operation.
.The bumper is damaged. Take the
vehicle to your dealer for repairs.
.Other conditions, such as vibrations
from a jackhammer or the
compression of air brakes on a very
large truck, are affecting system
performance.
Automatic Parking
Assist (APA)
Automatic Parking Assist (APA)
with Braking
If equipped, under certain conditions
APA with Braking can use sensors
based on sonar technology along the
vehicle’s front, rear and sides to detect
a parking spot, and automatically park
the vehicle with some driver
assistance. The vehicle will
automatically maneuver into a
detected spot moving at or near idle
speed. It does this by automatically
steering and braking while the driver
is responsible for acceleration and
gear shifting as needed. The driver
must always be prepared to apply
braking or additional acceleration, as
needed. A display and audible beeps
help to guide the parking maneuvers.
{Warning
APA may not always detect objects
in the parking space, objects that
are not rigid (e.g. shrubs and
chain-link fences), objects below the(Continued)
Warning (Continued)
bumper, objects high off the ground
(e.g. flatbed trucks), hanging
objects, objects below ground level
(e.g. large potholes), or moving
objects (e.g. pedestrians, cyclists,
vehicles). Always verify that the
parking space is appropriate for
parking a vehicle. APA may not
respond to changes in the parking
space, such as movement of an
adjacent vehicle, or a person or
object entering the parking space.
APA does not detect or avoid traffic
that is behind or alongside of the
vehicle. Always be prepared to stop
the vehicle during the parking
maneuver.
How to Activate Automatic Parking
To activate APA, press the soft-touch
button or hard switch
Ofor the
system to begin searching for a
parking space while driving forward at
no greater than 30 km/h (18 mph). By
default, APA searches for parallel
parking spaces to the right of the
vehicle up to the sensors’ range of
