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.

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

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

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)

Warning (Continued)
It could respond to a 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.
AEB and IBA can be disabled
through vehicle
personalization. To view
available settings for this
feature, touch the Settings
icon on the infotainment home
page. Select “Vehicle”to
display the list of available
options and select “Collision/
Detection Systems”.
A system unavailable message
may display if:
.The front of the vehicle or
windshield is not clean.
.Heavy rain or snow is
interfering with object
detection.
.There is a problem with the
StabiliTrak system.
The AEB system does not
need service.
Front Pedestrian
Braking (FPB) System
If equipped, the FPB system
may help avoid or reduce the
harm caused by front-end
crashes with pedestrians near
the forward path of the
vehicle when driving in a
forward gear. FPB displays an
amber indicator,
~, when a
nearby pedestrian is detected
ahead. When approaching a
detected pedestrian too
quickly, FPB provides a red
flashing alert on the
windshield and rapidly beeps
or pulses the driver seat. FPB
can provide a boost to braking
or automatically brake the
vehicle. This system includes
Intelligent Brake Assist (IBA),
and the Automatic Emergency
Braking (AEB) system may also

respond to pedestrians. See
Automatic Emergency Braking
(AEB)0273.
The FPB system can detect
and alert to pedestrians in a
forward gear at speeds
between 8 km/h (5 mph) and
80 km/h (50 mph). During
daytime driving, the system
detects pedestrians up to a
distance of approximately
40 m (131 ft). During nighttime
driving, system performance is
very limited.
{Warning
FPB does not provide an
alert or automatically brake
the vehicle, unless it detects
a pedestrian. FPB may not
detect pedestrians, including
children:
.When the pedestrian is
not directly ahead, fully
visible, or standing upright,
or when part of a group. (Continued)
Warning (Continued)
.Due to poor visibility,
including nighttime
conditions, fog, rain,
or snow.
.If the FPB sensor is
blocked by dirt, snow,
or ice.
.If the headlamps or
windshield are not cleaned
or in proper condition.
Be ready to take action and
apply the brakes. For more
information, see Defensive
Driving 0196. Keep the
windshield, headlamps, and
FPB sensor clean and in
good repair.
FPB can be set to Off, Alert,
or Alert and Brake through
vehicle personalization. To
view available settings for this
feature, touch the Settings
icon on the infotainment home
page. Select “Vehicle”to display the list of available
options and select
“Collision/

Detecting the Pedestrian
Ahead
FPB alerts and automatic
braking will not occur unless
the FPB system detects a
pedestrian. When a nearby
pedestrian is detected in front
of the vehicle, the pedestrian
ahead indicator will display
amber.
Front Pedestrian Alert

Cadillac Lyriq Owner Manual (GMNA-Localizing-U.S./Canada-15644413) -
2023 - CRC - 2/23/22
276 Driving and Operating
When the vehicle approaches
a pedestrian ahead too rapidly,
the red FPB alert display will
flash on the windshield. Eight
rapid high-pitched beeps will
sound from the front, or both
sides of the Safety Alert Seat
will pulse five times. When this
Pedestrian 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 Front Pedestrian
Alert occurs.
Automatic Braking
If FPB detects it is about to
crash into a pedestrian
directly ahead, and the brakes
have not been applied, FPB
may automatically brake
moderately or brake hard. This
can help to avoid some very
low speed pedestrian crashes
or reduce pedestrian injury.
FPB can automatically braketo detected pedestrians
between 8 km/h (5 mph) and
80 km/h (50 mph). Automatic
braking levels may be reduced
under certain conditions, such
as higher speeds.
If this happens, Automatic
Braking may engage the
Electric Parking Brake (EPB)
to hold the vehicle at a stop.
Release the EPB. A firm press
of the accelerator pedal will
also release Automatic
Braking and the EPB.
If equipped with the Night
Vision system, pedestrians
detected by the Night Vision
system will not cause
automatic braking to occur.{Warning
FPB may alert or
automatically brake the
vehicle suddenly in
situations where it is
unexpected and undesired.
It could falsely alert or brake
