306 DRIVING AND OPERATING
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press
[to set the
FCA timing to Far, Medium, or Near.
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.
If your vehicle is equipped with
Adaptive Cruise Control (ACC),
changing the FCA timing setting
automatically changes the following
gap setting (Far, Medium, or Near).
Following Distance Indicator
The following distance to a moving
vehicle ahead in your path is indicated
in following time in seconds on the
Driver Information Center (DIC). See
Driver Information Center (DIC) (Base
Level)
0116 or
Driver Information Center (DIC)
(Uplevel) 0119. The minimum
following time is 0.5 seconds away.
If there is no vehicle detected ahead,
or the vehicle ahead is out of sensor
range, dashes will be displayed.
Unnecessary Alerts
FCA may provide unnecessary alerts
for 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, this may correct the
issue:
.Clean the outside of the windshield
in front of the rearview mirror.
.Clean the entire front of the vehicle.
.Clean the headlamps.
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 in the path ahead
that is traveling in the same direction,
it can provide a boost to braking,
or automatically brake the vehicle, to
avoid a crash. 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. When detecting a vehicle,
the Forward Collision Alert (FCA)

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-15268585) -
2022 - CRC - 10/11/21
308 DRIVING AND OPERATING
AEB and IBA can be disabled through
vehicle personalization. See“Collision/
Detection Systems” underVehicle
Personalization 0126.
{Warning
Using AEB or IBA while towing a
trailer could cause you to lose
control of the vehicle and crash.
Turn the system to Alert, or if the
vehicle has ACC to Off, when
towing a trailer.
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/Electronic Stability
Control (ESC) 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 nearby
pedestrians 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)
0 306.
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.
.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 0217. Keep
the windshield, headlamps, and FPB
sensor clean and in good repair.

312 DRIVING AND OPERATING
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.
LCA may not operate when the LCA
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" underExterior Care0399.
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 LCA displays do not light up
when moving vehicles are in the side
blind zone or are rapidly approaching
this zone and the system is clean, the
system may need service. Take the
vehicle to your dealer.
Radio Frequency Information
See Radio Frequency Statement 0440.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. This system uses a camera
to detect lane markings. LKA may be
ready to assist at speeds between
80 km/h (50 mph) and 180 km/h
(112 mph). LKA may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking. It may also provide a Lane
Departure Warning (LDW) alert if the
vehicle unintentionally crosses a
detected lane marking. This system is
not intended to keep the vehicle
centered in the lane. LKA will not
assist or alert if the turn signal is
active in the direction of lane
departure, or if it detects that you are
accelerating, braking, or actively
steering. LKA can be overridden by
turning the steering wheel. If the
system detects you are steering
intentionally across a lane marker, the
LDW will not be given. Do not expect
the LDW to occur when you are
intentionally crossing a lane marker.{Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a lane
marking is detected.
The LKA and LDW systems
may not:
.Provide an alert or enough
steering assist to avoid a lane
departure or crash.
.Detect lane markings under poor
weather or visibility conditions.
This can occur if the windshield
or headlamps are blocked by dirt,
snow, or ice; if they are not in
proper condition; or if the sun
shines directly into the camera.
.Detect road edges.
.Detect lanes on winding or hilly
roads.
If LKA only detects lane markings
on one side of the road, it will only
assist or provide an LDW alert (Continued)

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-15268585) -
2022 - CRC - 10/11/21
DRIVING AND OPERATING 313
Warning (Continued)
when approaching the lane on the
side where it has detected a lane
marking. Even with LKA and LDW,
you must steer the vehicle. Always
keep your attention on the road and
maintain proper vehicle position
within the lane, or vehicle damage,
injury, or death could occur. Always
keep the windshield, headlamps,
and camera sensors clean and in
good repair. Do not use LKA in bad
weather conditions or on roads with
unclear lane markings, such as
construction zones.
{Warning
Using LKA on slippery roads could
cause loss of control of the vehicle
and a crash. Turn the system off.
{Warning
LKA will not alert the driver if a
towed trailer crosses into an
adjacent lane of travel. Serious
injury or property damage may
occur if the trailer moves into
another lane. Always monitor the
trailer position while towing to
make sure it is within the same
lane as the tow vehicle.
How the System Works
LKA uses a camera sensor installed on
the windshield ahead of the rearview
mirror to detect lane markings. It may
provide brief steering assist if it
detects an unintended lane departure.
It may further provide an audible alert
or the driver seat may pulse indicating
that a lane marking has been crossed.
The system does not provide a Lane
Departure Warning (LDW) when
intentionally steering across a lane
marker.To turn LKA on and off, press
Aon
the center stack. If equipped, the
indicator light on the button comes
on when LKA is on and turns off
when LKA is disabled.
When on,
Ais white, if equipped,
indicating that the system is not
ready to assist.
Ais green if LKA is
ready to assist. LKA may assist by
gently turning the steering wheel if
the vehicle approaches a detected
lane marking.
Ais amber when
assisting. It may also provide a Lane
Departure Warning (LDW) alert by
flashing
Aamber if the vehicle
crosses a detected lane marking.
Additionally, there may be three
beeps, or the driver seat may pulse
three times, on the right or left,
depending on the lane departure
direction.
Take Steering
The LKA system does not
continuously steer the vehicle. If LKA
does not detect active driver steering,
an alert and chime may be provided.

Headlamp Aiming
Front Headlamp Aiming
Headlamp aim has been preset and
should need no further adjustment.
If the vehicle is damaged in a crash,
the headlamp aim may be affected.
If adjustment to the headlamps is
necessary, see your dealer.
Bulb Replacement
LED Lighting
This vehicle has LED lamps. For
replacement of any LED lighting
assembly, contact your dealer.
Electrical System
Electrical System Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is too
heavy, the circuit breaker opens and
closes, protecting the circuit until the
current load returns to normal or the
problem is fixed. This greatly reduces
the chance of circuit overload and fire
caused by electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be borrowed.Choose some feature of the vehicle
that is not needed to use and replace
it as soon as possible.
To check a fuse, look at the band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure to
replace a bad fuse with a fuse of the
identical size and rating.

Replacing a Blown Fuse
1. Turn off the ignition.
2. Locate the fuse puller in the enginecompartment fuse block.
3. Use the fuse puller to remove thefuse from the top or side, as shown
above. 4. If the fuse must be replaced
immediately, borrow a replacement
fuse with the same amperage from
the fuse block. Choose a vehicle
feature that is not needed to safely
operate the vehicle. Repeat
Steps 2-3.
5. Insert the replacement fuse into the empty slot of the blown fuse.
At the next opportunity, see your
dealer to replace the blown fuse.
Headlamp Wiring
An electrical overload may cause the
lamps to go on and off, or in some
cases to remain off. Have the
headlamp wiring checked right away if
the lamps go on and off or remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop. Wiper function is
available immediately after the wiper
switch is set to off, and back to on.

386 VEHICLE CARE
such as troughs or ruts, is normal.
If the vehicle is vibrating when driving
on a smooth road, the tires and
wheels may need to be rebalanced.
See your dealer for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or corroded.
If wheel nuts keep coming loose, the
wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel leaks
air, replace it. Some aluminum wheels
can be repaired. See your dealer if any
of these conditions exist.
Your dealer will know the kind of
wheel that is needed.
Each new wheel should have the same
load-carrying capacity, diameter,
width, offset, and be mounted the
same way as the one it replaces.
Replace wheels, wheel bolts, wheel
nuts, or Tire Pressure Monitor System
(TPMS) sensors with new GM original
equipment parts.
{Warning
Using the wrong replacement
wheels, wheel bolts, or wheel nuts
can be dangerous. It could affect
the braking and handling of the
vehicle. Tires can lose air, and
cause loss of control, causing a
crash. Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.
Caution
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or odometer
calibration, headlamp aim, bumper
height, vehicle ground clearance,
and tire or tire chain clearance to
the body and chassis.
Used Replacement Wheels
{Warning
Replacing a wheel with a used one
is dangerous. How it has been used
or how far it has been driven may
be unknown. It could fail suddenly
and cause a crash. When replacing
wheels, use a new GM original
equipment wheel.
Tire Chains
{Warning
Do not use tire chains. There is not
enough clearance. Tire chains used
on a vehicle without the proper
amount of clearance can cause
damage to the brakes, suspension,
or other vehicle parts. The area
damaged by the tire chains could
cause loss of control and a crash.
Use another type of traction device
only if its manufacturer
recommends it for the vehicle's tire
size combination and road
conditions. Follow that(Continued)
