mirrors before moving forward or
backing.
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.
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 0399.
.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 a very
large truck, are affecting system
performance.

300 DRIVING AND OPERATING
Turning the Feature On or Off
TouchXon the center stack to turn
on or off the Front and Rear Park
Assist, Reverse Automatic Braking
(RAB), and the Backing Warning
System at the same time. The
indicator light next to the button
comes on when the features are on
and turns off when the features have
been disabled.
Turn off Park Assist when towing a
trailer.
To turn the RPA symbols or guidance
lines (on some models) on or off, see
“Rear Camera Park Assist Symbols”
under Vehicle Personalization 0126.
Automatic Parking
Assist (APA)
If equipped, APA searches for and
steers the vehicle into parallel and
perpendicular parking spots. When
using APA, you must still shift gears
while the system applies the brakes
and accelerator. A display and audible
beeps help to guide parking
maneuvers.
Do not use APA when towing a trailer.
{Warning
APA may not detect objects in the
parking space, objects that are soft
or narrow, objects high off the
ground such as flatbed trucks,
objects below ground level such as
large potholes, or moving objects
(e.g. pedestrians). Always verify that
the parking space is appropriate for
parking a vehicle. APA does 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.
Touch
Oon the center stack to
enable the system to search for a
parking space that is large enough and
within 1.5 m (5 ft) of the vehicle. The
vehicle speed must be below
30 km/h (18 mph). The system cannot:
.Detect whether it is a legal parking
space.
.Park exactly lined up with the
vehicle next to it if the spot is
approached at an angle or if the
parking space is angled.
.Park exactly centered in a spot that
is marked too large.
.Always detect short curbs.

304 DRIVING AND OPERATING
Rear Cross Traffic Alert
(RCTA) System
If equipped, RCTA displays a red
warning triangle with a left or right
pointing arrow to warn of traffic
coming from the left or right. This
system detects objects coming from
up to 20 m (65 ft) from the left or
right side of the vehicle. When an
object is detected, either three beeps
sound from the left or right or three
Safety Alert Seat pulses occur on the
left or right side, depending on the
direction of the detected vehicle.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out from
the back of the vehicle do not move
further back when a trailer is towed.
Turning the Feature On or Off
Turn off RCTA when towing a trailer.
RCTA can also be turned on or off
through vehicle personalization. See
“Collision/Detection Systems”under
Vehicle Personalization 0126.
Assistance Systems for
Driving
If equipped, when driving the vehicle
in a forward gear, Forward Collision
Alert (FCA), Lane Departure Warning
(LDW), Lane Keep Assist (LKA), Side
Blind Zone Alert (SBZA), Lane Change
Alert (LCA), Automatic Emergency
Braking (AEB), and/or the Front
Pedestrian Braking (FPB) System can
help to avoid a crash or reduce crash
damage.
Forward Collision Alert
(FCA) System
The FCA system may help to avoid or
reduce the harm caused by front-end
crashes. When approaching a vehicle
ahead too quickly, FCA provides a red
flashing alert on the windshield and
rapidly beeps or pulses the driver seat.
FCA also lights an amber visual alert
if following another vehicle too
closely.
FCA detects vehicles within a distance
of approximately 60 m (197 ft) and
operates at speeds above 8 km/h
(5 mph). If the vehicle has Adaptive Cruise Control (ACC), it can detect
vehicles to distances of approximately
110 m (360 ft) and operates at all
speeds. See
Adaptive Cruise Control
(Advanced) 0270.
{Warning
FCA is a warning system and does
not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. It also may not
provide any warning at all. FCA
does not warn of pedestrians,
animals, signs, guardrails, bridges,
construction barrels, or other
objects. Be ready to take action and
apply the brakes. See Defensive
Driving 0217.
FCA can be disabled through vehicle
personalization. See "Collision/
Detection Systems" under Vehicle
Personalization 0126.

vehicle ahead indicator light will be
on. SeeForward Collision Alert (FCA)
System 0304.
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.
{Warning
AEB may automatically brake the
vehicle suddenly in situations
where it is unexpected and
undesired. It could respond to a (Continued)
Warning (Continued)
turning vehicle ahead, guardrails,
signs, and other non-moving
objects. To override AEB, firmly
press the accelerator pedal, if it is
safe to do so.
Intelligent Brake Assist (IBA)
IBA may activate when the brake
pedal is applied quickly by providing a
boost to braking based on the speed
of approach and distance to a vehicle
ahead.
Minor brake pedal pulsations or pedal
movement during this time is normal
and the brake pedal should continue
to be applied as needed. IBA will
automatically disengage only when
the brake pedal is released.
{Warning
IBA may increase vehicle braking in
situations when it may not be
necessary. You could block the flow
of traffic. If this occurs, take your
foot off the brake pedal and then
apply the brakes as needed.

2022 - CRC - 10/11/21
VEHICLE CARE 353
The brake/clutch master cylinder
reservoir is filled with GM approved
DOT 4 brake fluid as indicated on the
reservoir cap. SeeEngine Compartment
Overview 0331 for the location of the
reservoir.
Checking Brake Fluid
Place the vehicle in P (Park) or
Neutral with the parking brake applied
if equipped with a manual
transmission. On a level surface, the
brake fluid level should be between
the minimum and maximum marks
on the brake fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.Normal brake lining wear. When
new linings are installed, the fluid
level goes back up.
.A fluid leak in the brake/clutch
hydraulic system. Have the brake/
clutch hydraulic system fixed. With
a leak, the brakes will not work well.
Always clean the brake fluid reservoir
cap and the area around the cap
before removing it. Do not top off the brake/clutch fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are installed.
Add or remove fluid, as necessary,
only when work is done on the brake/
clutch hydraulic system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You or
others could be burned, and the
vehicle could be damaged. Add
brake fluid only when work is done
on the brake/clutch hydraulic
system.
When the brake/clutch fluid falls to a
low level, the brake warning light
comes on. See Brake System Warning
Light 0108.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid at
the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0410. What to Add
Use only GM approved DOT 4 brake
fluid from a clean, sealed container.
See
Recommended Fluids and
Lubricants 0420.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the paint
finish can be damaged. Immediately
wash off any painted surface.
Battery - North America
The original equipment battery is
maintenance free. Do not remove the
cap and do not add fluid.
Refer to the replacement number
shown on the original battery label
when a new battery is needed.
