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
0364.
.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.
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)
Enhanced Automatic
Parking Assist (APA)
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 or unpark
the vehicle with some driver
assistance. The vehicle will
automatically maneuver into a

Cadillac Lyriq Owner Manual (GMNA-Localizing-U.S./Canada-15644413) -
2023 - CRC - 2/23/22
Driving and Operating 263
detected spot moving at or
near idle speed. It does this by
automatically steering,
braking, accelerating, and gear
shifting. 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
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(Continued)
Warning (Continued)
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
Oon
the infotainment screen for
the system to begin searching
for a parking space while
driving forward at no greater
than 30 km/h (18 mph). APA
searches for parking spaces,
to the left or right of the
vehicle, up to the sensors’
ranges of 1.5 m (5 ft). To
search for a parking space to
the left, turn on the left turn
signal or, if available, change the side selection in the
infotainment display. To
choose or change the parking
mode, make a selection on the
infotainment display.
APA cannot park in all empty
parking spots. The parking
spot must:
.Be sufficiently large to fit the
vehicle comfortably.
.Have an adjacent vehicle,
wall, or pillar for the system
to align to.
After completely passing an
eligible parking spot, a beep
sounds and a notification to
stop the vehicle is displayed in
the driver information center.
Generally, APA selects the
nearest empty parking spot

Reverse Automatic
Braking (RAB)
Backing Warning and
Reverse Automatic
Braking (RAB)
Vehicles with Adaptive Cruise
Control (ACC) have the
Backing Warning System and
Reverse Automatic Braking
(RAB) system. When in
R (Reverse), Backing Warning
alerts of rear objects at
vehicle 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 SafetyAlert 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, animals, or objects
below the bumper or that
are too close or too far from
the vehicle. In some
situations, such as at higher
backing speeds, there may
not be enough time for the
short, sharp application of
the vehicle brake system to
occur. To prevent injury,
death, or vehicle damage,
even with the Backing
Warning System, always
check the area around the
vehicle and check all mirrors
before backing.
When the vehicle is in
R (Reverse), if the system
detects the vehicle is backing
too fast to avoid a crash with
a detected object behind your
vehicle in your path, it may
automatically brake hard to a
stop to help avoid or reduce
the harm caused by a backing
crash.
{Warning
RAB may not avoid many
types of backing crashes. Do
not wait for the automatic
braking to apply. This
system is not designed to
replace driver braking and
only works in R (Reverse)
when an object is detected
directly behind the vehicle.
It may not brake or stop in
time to avoid a crash. It will
not brake for objects when
the vehicle is moving at very
low speeds. It does not
detect children, pedestrians,
bicyclists, animals, or objects

below the bumper or that
are too close or too far from
the vehicle. To prevent
injury, death, or vehicle
damage, even with RAB,
always check the area
around the vehicle before
and while backing.
Pressing the brake pedal after
the vehicle comes to a stop
will release RAB. If the brake
pedal is not pressed soon
after the stop, the Electric
Parking Brake (EPB) may be
set. When it is safe, press the
accelerator pedal firmly at any
time to override RAB.
{Warning
There may be instances
where unexpected or
undesired automatic braking
occurs. If this happens,
either press the brake pedal
or firmly press the (Continued)
Warning (Continued)
accelerator pedal to release
the brakes from the RAB
system. Before releasing the
brakes, check the RVC and
check the area around the
vehicle to make sure it is
safe to proceed.
Unexpected braking events
are possible with a static
installed accessory, such as a
bike rack or hitch-mounted
cargo carrier.
Rear Pedestrian Alert
Under certain conditions, this
feature can provide alerts for
a pedestrian within the
system’s range directly behind
the vehicle. This feature only
works in R (Reverse) below
12 km/h (8 mph), and detects
pedestrians up to 8 m (26 ft)
away during daytime driving.
During nighttime driving,
feature performance is very
limited.
Rear Pedestrian Alert Indicator
When a pedestrian is detected
within the system’s range
directly behind the vehicle, this
symbol flashes amber on the
infotainment display, along
with five beeps from the rear,
or if equipped, two pulses
from both sides of the driver
seat. When a pedestrian is
detected close to the vehicle,
the symbol flashes red on the
infotainment display, along
with ten beeps from the rear,
or if equipped, seven pulses
from both sides of the
driver seat.

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 much too closely.
FCA detects vehicles within a
distance of approximately
110 m (360 ft) and operates at
all speeds.
{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

Detecting the Vehicle
Ahead
FCA warnings will not occur
unless the FCA system
detects a vehicle ahead. When
a vehicle is detected, the
vehicle ahead indicator will display green. Vehicles may
not be detected on curves,
highway exit ramps, or hills,
due to poor visibility; or if a
vehicle ahead is partially
blocked by pedestrians or
other objects. 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
(Continued)
Warning (Continued)
windshield, headlamps, and
FCA sensors clean and in
good repair.
Collision Alert
When your vehicle approaches
another detected vehicle too
rapidly, the red FCA display
will flash on the windshield.
Also, eight rapid high-pitched
beeps will sound from the
front, or both sides of the
Safety Alert Seat will pulse
five times. Continue to apply
the brake pedal as needed.

Automatic Emergency
Braking (AEB)
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
ahead in your path that is
traveling in the same direction
that you may be about to
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. This is shown by the
FCA vehicle ahead indicator
being lit. See Forward Collision
Alert (FCA) System0270. The system works when
driving in a forward gear
above 4km/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.
.Detect a vehicle when
weather limits visibility,
such as in fog, rain,
or snow.
(Continued)
Warning (Continued)
.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. (Continued)
