Parking Assist
If available, Front and Rear Parking
Assist (FRPA) uses sensors on the
front and rear bumpers to detect
objects while parking the vehicle.
It operates at speeds less than
8 km/h (5 mph). FRPA uses audio
beeps to provide distance and
system information.
Keep the sensors on the vehicle's
front and rear bumpers clean to
ensure proper operation.
See Parking Assist on page 9-34.
Power Outlets
The accessory power outlet can be
used to plug in electrical equipment,

When Should an Airbag
Inflate?
This vehicle is equipped with
airbags. SeeAirbag System on
page 3-23. Airbags are designed to
inflate if the impact exceeds the
specific airbag system's deployment
threshold. Deployment thresholds
are used to predict how severe a
crash is likely to be in time for the
airbags to inflate and help restrain
the occupants. The vehicle has
electronic sensors that help the
airbag system determine the
severity of the impact. Deployment
thresholds can vary with specific
vehicle design.
Frontal airbags are designed to
inflate in moderate to severe frontal
or near frontal crashes to help
reduce the potential for severe
injuries, mainly to the driver's or
front outboard passenger's head
and chest.
Whether the frontal airbags will or
should inflate is not based primarily
on how fast the vehicle is traveling. It depends on what is hit, the
direction of the impact, and how
quickly the vehicle slows down.
Frontal airbags may inflate at
different crash speeds depending on
whether the vehicle hits an object
straight on or at an angle, and
whether the object is fixed or
moving, rigid or deformable, narrow
or wide.
Frontal airbags are not intended to
inflate during vehicle rollovers, in
rear impacts, or in many side
impacts.
In addition, the vehicle has
advanced technology frontal
airbags. Advanced technology
frontal airbags adjust the restraint
according to crash severity.
Knee airbags (if equipped) are
designed to inflate in moderate to
severe frontal or near frontal
impacts. Knee airbags are not
designed to inflate during vehicle
rollovers, in rear impacts, or in many
side impacts.
Seat-mounted side impact airbags
are designed to inflate in moderate
to severe side crashes depending
on the location of the impact.
Seat-mounted side impact airbags
are not designed to inflate in frontal
impacts, near frontal impacts,
rollovers, or rear impacts.
A seat-mounted side impact airbag
is designed to inflate on the side of
the vehicle that is struck.
Roof-rail airbags are designed to
inflate in moderate to severe side
crashes depending on the location
of the impact. In addition, these
roof-rail airbags are designed to
inflate during a rollover or in a
severe frontal impact. Roof-rail
airbags are not designed to inflate in
rear impacts. Both roof-rail airbags
will inflate when either side of the
vehicle is struck, if the sensing
system predicts that the vehicle is
about to roll over on its side, or in a
severe frontal impact.

Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position. The
passenger airbag status indicator
will light on the instrument panel
when the vehicle is started.United States
Canada and Mexico
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or OFF, or the symbol for
on or off, will be visible. See
Passenger Airbag Status Indicator
on page 5-12.
The passenger sensing system
turns off the front outboard
passenger frontal airbag and knee
airbag (if equipped) under certain conditions. No other airbag is
affected by the passenger sensing
system.
The passenger sensing system
works with sensors that are part of
the front outboard passenger seat.
The sensors are designed to detect
the presence of a properly seated
occupant and determine if the front
outboard passenger frontal airbag
and knee airbag (if equipped)
should be allowed to inflate or not.
According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.
Whenever possible, children age
12 and under should be secured in
a rear seating position.
Never put a rear-facing child seat in
the front. This is because the risk to
the rear-facing child is so great,
if the airbag inflates.

diagnostic module, steering wheel,
instrument panel, any of the airbag
modules, ceiling or pillar garnish
trim, overhead console, front
sensors, side impact sensors,
or airbag wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle has a
passenger sensing system for the
front outboard passenger position,
which includes sensors that are part
of the passenger seat. The
passenger sensing system may not
operate properly if the original seat
trim is replaced with non-GM
covers, upholstery, or trim; or with
GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad
or device, installed under or on top
of the seat fabric, could also
interfere with the operation of the
passenger sensing system. Thiscould either prevent proper
deployment of the passenger
airbag(s) or prevent the passenger
sensing system from properly
turning off the passenger airbag(s).
See
Passenger Sensing System on
page 3-30.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires
and Wheels on page 10-52 for
additional important information.
If you have to modify your vehicle
because you have a disability and
you have questions about whether
the modifications will affect the
vehicle's airbag system, or if you
have questions about whether the
airbag system will be affected if the
vehicle is modified for any other
reason, call Customer Assistance.
See Customer Assistance Offices
on page 13-3.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag readiness light is working. See
Airbag Readiness Light on
page 5-12.
{Caution
If an airbag covering is damaged,
opened, or broken, the airbag
may not work properly. Do not
open or break the airbag
coverings. If there are any

8-6 Climate Controls
Sensors
The solar sensor, located on top of
the instrument panel near the
windshield, monitors the solar heat.
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.
Air Vents
Use the louvers located on the air
vents to change the direction of the
airflow.
Use the thumbwheels near the air
vents to control the amount of
airflow or to shut off the airflow.
Operation Tips
.Keep all outlets open whenever
possible for best system
performance.
.Keep the paths under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
.Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Maintenance
Air Intake
Clear away any ice, snow, or leaves
from the air intake at the base of the
windshield that can block the flow of
air into the vehicle.
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
SeeMaintenance Schedule on
page 11-2. To find out what type of
filter to use, see Maintenance
Replacement Parts on page 11-12.

detected on curves, highway exit
ramps, or hills; or due to poor
visibility. FCA will not detect another
vehicle ahead until it is completely
in the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.Collision Alert
When your vehicle approaches
another detected vehicle too rapidly,
the FCA display will come on. Also,
eight rapid high-pitched beeps will
sound from the front. When this
Collision Alert occurs, the brake
system may prepare for driver
braking to occur more rapidly which
can cause a brief, mild deceleration.
Continue to apply the brake pedal
as needed. Cruise control may be
disengaged when the Collision Alert
occurs.
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press
[to set the
FCA timing to far, medium, or near,
or on some vehicles, Off. The first
button press shows the current
setting on the DIC. Additional button
presses will change this setting. The
chosen setting will remain until it is
changed and will affect the timing of
both the Collision Alert and the
Tailgating Alert features. The timing
of both alerts will vary based on
vehicle speed. The faster the
vehicle speed, the farther away the

alert will occur. Consider traffic and
weather conditions when selecting
the alert timing. The range of
selectable alert timings may not be
appropriate for all drivers and
driving conditions.
Unnecessary Alerts
FCA may provide unnecessary
alerts to turning vehicles, vehicles in
other lanes, objects that are not
vehicles, or shadows. These alerts
are normal operation and the
vehicle does not need service.
Cleaning the System
If the FCA system does not seem to
operate properly, cleaning the
outside of the windshield in front of
the rearview mirror may correct the
issue.
Parking Assist
If equipped, the Front and Rear
Parking Assist (FRPA) system,
assists the driver with parking and
avoiding objects. FRPA operates at
speeds less than 8 km/h (5 mph).The sensors on the front and rear
bumper detect objects up to 1.2 m
(4 ft) in front of the vehicle, 2.5 m
(8 ft) behind the vehicle, and at least
25 cm (10 in) off the ground and
below liftgate level. This detection
distance may be less during warmer
or humid weather.
{Warning
The parking 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 8 km/h
(5 mph). To prevent injury, death,
or vehicle damage, even with
parking assist, always check the
area around the vehicle and
check all mirrors before moving
forward or backing.
How the System Works
When the vehicle is shifted into
R (Reverse) the front and rear
sensors are automatically turned on.
After the vehicle is shifted out of
R (Reverse), the rear sensors are
turned off and the front sensors stay
on until the vehicle is above a
speed of 8 km/h (5 mph). For the
front park assist system to be active
again without shifting into
R (Reverse), the park assist button
on the center stack, forward of the
shift lever, must be pressed. See
“Turning the System On and Off”
later in this section.
FRPA operates only at speeds less
than 8 km/h (5 mph).
When the vehicle is in N (Neutral),
the system may be active. If the
vehicle is in a car wash, the sensors
may detect objects in the car wash.
See
“Turning the System On and
Off” later in this section to turn the
system off.

Driving and Operating 9-35
High-toned beeps from the front
speakers are for objects detected
near the front bumper. Low-toned
beeps from the rear speakers are
for objects detected near the rear
bumper. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is a
continuous tone for five seconds.
Objects Detected by Both the
Front and Rear Sensors
In general, if objects are detected at
the same time near both the front
and rear bumpers while backing up,
the beeps only sound to indicate
that objects are close to the rear
bumper.
However, if an object comes within
0.3 m (1 ft) of the front bumper while
the vehicle is backing up and at the
same time there is another object
further than 0.3 m (1 ft) from the rear
bumper, then higher-pitched beeps
only sound to indicate the front
object.Turning the System On and Off
The FRPA system can be turned on
and off by pressing the park assist
button on the center stack, forward
of the shift lever.
The indicator light in the button
comes on when the system is
turned on.
When the system is off, the indicator
light in the button is off or PARK
ASSIST OFF briefly displays on the
Driver Information Center (DIC).
FRPA defaults to the on setting
each time the vehicle is started.
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, take the
vehicle to your dealer to repair the
system.
PARK ASSIST OFF: If the FRPA
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.
.The sensors are not clean. Keep
the vehicle's bumpers free of
mud, dirt, snow, ice and slush.
For cleaning instructions, see
Exterior Care on page 10-68.
.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

lane over that is in the side blind
zone. This indicates it may be
unsafe to change lanes. Before
making a lane change, check the
SBZA display, check mirrors, glance
over your shoulder, and use the turn
signals.
Left Side MirrorDisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror SBZA displays will
briefly come on to indicate the
system is operating. When the
vehicle is in a forward gear, the left-
or right-side mirror display will light
up if a moving vehicle is detected in
that blind zone. If the turn signal is
activated in the same direction of a
detected vehicle, this display will
flash as an extra warning not to
change lanes. SBZA can be disabled through
vehicle personalization. See
“Collision/Detection Systems”
under
Vehicle Personalization on
page 5-30. If SBZA is disabled by
the driver, the SBZA mirror displays
will not light up.
When the System Does Not
Seem to Work Properly
SBZA displays may not come on
when passing a vehicle quickly or
for a stopped vehicle. SBZA may
alert to objects attached to the
vehicle, such as a bicycle, or object
extending out to either side of the
vehicle. This is normal system
operation; the vehicle does not need
service.
SBZA may not always alert the
driver to vehicles in the side blind
zone, especially in wet conditions.
The system does not need to be
serviced. The system may light up
due to guardrails, signs, trees,
shrubs, and other non-moving objects. This is normal system
operation; the vehicle does not need
service.
SBZA may not operate when the
SBZA sensors in the left or right
corners of the rear bumper are
covered with mud, dirt, snow, ice,
or slush, or in heavy rainstorms. For
cleaning instructions, see "Washing
the Vehicle" under
Exterior Care on
page 10-68. If the DIC still displays
the system unavailable message
after cleaning both sides of the
vehicle toward the rear corners of
the vehicle, see your dealer.
If the SBZA displays do not light up
when vehicles are in the blind zone
and the system is clean, the system
may need service. Take the vehicle
to your dealer.
When SBZA is disabled for any
reason other than the driver turning
it off, the Side Blind Zone Alert On
option will not be available on the
personalization menu.
