Turning the Feature On or Off
Bicyclist Detection can be turned on or off
through vehicle settings. To view available
settings from the infotainment screen, touch
Settings > Vehicle > Collision/Detection
Systems.
Blind Zone Steering Assist (BZSA)
If equipped, the Blind Zone Steering Assist
(BZSA) system can detect a potential crash
with a moving vehicle in the lane you are
entering. It provides a brief, urgent turn of
the steering wheel to alert you to take
action to avoid a collision.
BZSA works with the Lane Keep Assist (LKA).
BZSA operates when the vehicle is in a
forward gear, and only when LKA is enabled
and able to assist. SeeLane Keep Assist
(LKA) 0245.
BZSA will provide a steering correction when
your vehicle is about to leave the current
lane of travel, with the possibility of a
collision with a vehicle in the adjacent lane.
This steering correction happens closer to
the center of the lane and has a stronger
steering correction than LKA. Unlike LKA, the
steering correction with BSZA will happen
even if your turn signal is on in the
direction of lane departure. In addition to the BZSA steering
intervention, the
Awill turn amber, six
beeps or six seat pulses will occur,
if equipped with Safety Alert Seat, and
8or|will flash on the outside
rear view mirror.
{Warning
Do not rely on Blind Zone Steering Assist
(BZSA) to prevent crashes. This system
does not replace the need to pay
attention and drive safely. Failure to use
proper care when driving may result in
vehicle damage, injury, or death.
.BZSA performance may be affected by
weather and road conditions.
.BZSA does not provide steering
assistance to avoid a vehicle that is in,
or has entered, your lane of travel.
.BZSA will not prevent a towed trailer
from crossing into the adjacent lane.
Always monitor the trailer position
while towing to ensure it is in the
same lane as your vehicle. BZSA is
only designed to detect when your
vehicle unintentionally crosses
detected lane lines.
Traffic Sign Assistant
If equipped, Traffic Sign Assistant recognizes
designated traffic signs via the front camera
located behind the windshield in front of the
interior rear view mirror, and displays the
detected speed limit in the Driver
Information Center (DIC). Additionally, speed
limit information from the navigation
system map database may be used.
Caution
The system is intended to assist the
driver within a defined speed range to
discern certain traffic signs. Always pay
attention to posted speed limit signs.
Do not ignore traffic signs which are not
displayed by the system.
The system does not discern any signs
other than the conventional traffic signs
that might give or end a speed limit.
It may not detect some electronic speed
signs.

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 unintendedlane 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
non the
center stack. If equipped, the indicator light
on the button comes on when LKA is on and
turns off when LKA is disabled. In some
vehicles a long press of over three seconds
is required to turn LKA off.
When on,

detected lane marking.
nis amber when
assisting. It may also provide a Lane
Departure Warning (LDW) alert by flashing
namber 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. Steer the vehicle to dismiss. LKA
may become temporarily unavailable after
repeated take steering alerts.
When the System Does Not Seem to
Work Properly
The system performance may be
affected by:
.Close vehicles ahead.
.Sudden lighting changes, such as when
driving through tunnels.
.Banked roads.
.Roads with poor lane markings, such as
two-lane roads.
If the LKA system is not functioning
properly when lane markings are clearly
visible, cleaning the windshield may help.
A camera blocked message may display if
the camera is blocked. Some driver
assistance systems may have reduced
performance or not work at all. An LKA or
LDW unavailable message may display if the
systems are temporarily unavailable. This
message could be due to a blocked camera.

Trailer Towing
General Towing Information
Only use towing equipment that has been
designed for the vehicle. Contact your dealer
or trailering dealer for assistance with
preparing the vehicle to tow a trailer. Read
the entire section before towing a trailer.
To tow a disabled vehicle, seeTransporting
a Disabled Vehicle 0317. To tow the vehicle
behind another vehicle such as a motor
home, see Recreational Vehicle Towing
0 318.
Only use unleaded gasoline with an octane
rating of 89 or higher. Using gasoline with a
lower octane rating while towing may
damage the engine and may not be covered
by the vehicle warranty. See Recommended
Fuel 0247.
Driving Characteristics and
Towing Tips
{Warning
You can lose control when towing a
trailer if the correct equipment is not
used or the vehicle is not driven properly.
(Continued)
Warning (Continued)
For example, if the trailer is too heavy or
the trailer brakes are inadequate for the
load, the vehicle may not stop as
expected. You and others could be
seriously injured. The vehicle may also be
damaged, and the repairs would not be
covered by the vehicle warranty. Pull a
trailer only if all the steps in this section
have been followed. Ask your dealer for
advice and information about towing a
trailer with the vehicle.
Driving with a Trailer
Trailering is different than just driving the
vehicle by itself. Trailering means changes in
handling, acceleration, braking, durability,
and fuel economy. Successful, safe trailering
takes correct equipment, and it has to be
used properly.
The following information has many
time-tested, important trailering tips and
safety rules. Many of these are important
for your safety and that of your passengers.
Read this section carefully before pulling a
trailer. When towing a trailer:
.Become familiar with and follow all state
and local laws that apply to trailer
towing. These requirements vary from
state to state.
.State laws may require the use of
extended side view mirrors. If your
visibility is limited or restricted while
towing, install extended side view mirrors,
even if not required.
.Do not tow a trailer during the first
800 km (500 mi) of vehicle use to prevent
damage to the engine, axle, or other
parts.
.GM recommends performing an oil
change to the vehicle before heavy
towing.
.Do not drive over 80 km/h (50 mph) and
do not make starts at full throttle during
the first 800 km (500 mi) of trailer
towing.
.Vehicles can tow in D (Drive). If the
transmission downshifts too often, a
lower gear may be selected using Manual
Mode. See
Manual Mode 0185.

Driving and Operating 251
The following advanced driver assistance
features should be turned off when towing
a trailer, and may turn off automatically
when a trailer is detected:
.Park Assist
.Reverse Automatic Braking (RAB)
.Rear Cross Traffic Alert (RCTA)
.Rear Cross Traffic Braking (RCTB)
.Lane Change Alert (LCA)
.Super Cruise and Adaptive Cruise
Control (ACC), unless equipped with
trailering functionality, see Adaptive
Cruise Control (Advanced).
Automatic Emergency Braking (AEB) and
Front Pedestrian Braking (FPB) should be set
to Alert unless equipped with Super Cruise.
Do not use Automatic Parking Assist (APA)
while towing a trailer.
{Warning
To prevent serious injury or death from
carbon monoxide (CO), when towing a
trailer:
.Do not drive with the liftgate, trunk/
hatch, or rear-most window open. (Continued)
Warning (Continued)
.Fully open the air outlets on or under
the instrument panel.
.Adjust the climate control system to a
setting that brings in only outside air.
See“Climate Control Systems” in the
Index.
For more information about carbon
monoxide, see Engine Exhaust 0181.
Towing a trailer requires experience. The
combination of the vehicle and trailer is
longer and not as responsive as the vehicle
itself. Become familiar to the handling and
braking by driving on a level road surface
before driving on public roads.
The trailer structure, the tires, and the
brakes must be all be rated to carry the
intended cargo. Inadequate trailer
equipment can cause the combination to
operate in an unexpected or unsafe manner.
Before driving, inspect all trailer hitch parts
and attachments, safety chains, electrical
connectors, lamps, tires, and mirrors. See
Towing Equipment 0256. If the trailer has
electric brakes, start the combination
moving and then manually apply the trailer
brake controller to check that the trailer brakes work. During the trip, occasionally
check that the cargo and trailer are secure
and that the lamps and any trailer brakes
are working.Towing with a Stability Control System
When towing, the stability control system
might be heard. The system reacts to
vehicle movement caused by the trailer,
which mainly occurs during cornering. This is
normal when towing heavier trailers.
Following Distance
Stay at least twice as far behind the vehicle
ahead as you would when driving without a
trailer. This can help to avoid heavy braking
and sudden turns.
Passing
More passing distance is needed when
towing a trailer. The combination of the
vehicle and trailer will not accelerate as
quickly and is much longer than the vehicle
alone. It is necessary to go much farther
beyond the passed vehicle before returning
to the lane. Pass on level roadways. Avoid
passing on hills if possible.

17180837) - 2024 - CRC - 2/28/23
252 Driving and Operating
Backing Up
Hold the bottom of the steering wheel with
one hand. To move the trailer to the left,
move that hand to the left. To move the
trailer to the right, move that hand to the
right. Always back up slowly and, if possible,
have someone guide you.
Making TurnsCaution
Turn more slowly and make wider arcs
when towing a trailer to prevent damage
to your vehicle. Making very sharp turns
could cause the trailer to contact the
vehicle.
Make wider turns than normal when towing,
so the trailer will not go over soft shoulders,
over curbs, or strike road signs, trees,
or other objects. Always signal turns well in
advance. Do not steer or brake suddenly.
Driving on Grades
Reduce speed and shift to a lower gear
before starting down a long or steep
downhill grade. If the transmission is not
shifted down, the brakes may overheat and
result in reduced braking efficiency. The vehicle can tow in D (Drive). Shift the
transmission to a lower gear if the
transmission shifts too often under heavy
loads and/or hilly conditions.
When towing at higher altitudes, engine
coolant will boil at a lower temperature
than at lower altitudes. If the engine is
turned off immediately after towing at high
altitude on steep uphill grades, the vehicle
could show signs similar to engine
overheating. To avoid this, let the engine
run, preferably on level ground, with the
transmission in P (Park) for a few minutes
before turning the engine off. If the
overheat warning comes on, see
Engine
Overheating 0271.
Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and trailer on a
level surface when possible. When parking your vehicle and your trailer
on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet. Turn the wheels into
the curb if facing downhill or into traffic
if facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, gradually release the brake pedal to
allow the chocks to absorb the load of
the trailer.
4. Reapply the brake pedal. Then apply the parking brake and shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
.Start the engine.
.Shift into the desired gear.
.Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.

Driving and Operating 253
Maintenance When Trailer Towing
The vehicle needs service more often when
used to tow trailers. SeeMaintenance
Schedule 0330. It is especially important to
check the automatic transmission fluid,
engine oil, axle lubricant, belts, cooling
system, and brake system before and during
each trip.
Check periodically that all nuts and bolts on
the trailer hitch are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily
overheat during severe operating conditions.
See Engine Overheating 0271.
Trailer Towing
Caution
Towing a trailer improperly can damage
the vehicle and result in costly repairs
not covered by the vehicle warranty. To
tow a trailer correctly, follow the
directions in this section and see your
dealer for important information about
towing a trailer with the vehicle. Trailering is different than just driving the
vehicle by itself. Trailering means changes in
handling, acceleration, braking, durability,
and fuel economy. Successful, safe trailering
takes correct equipment, and it has to be
used properly.
The following information has many
time-tested, important trailering tips and
safety rules. Many of these are important
for your safety and that of your passengers.
Read this section carefully before pulling a
trailer.
Trailer Weight
{Warning
Never exceed the towing capacity for
your vehicle.
Safe trailering requires monitoring the
weight, speed, altitude, road grades, outside
temperature, dimensions of the front of the
trailer, and how frequently the vehicle is
used to tow a trailer.
Trailer Weight Ratings
When towing a trailer, the combined weight
of the vehicle, vehicle contents, trailer, and
trailer contents must be below all of the
maximum weight ratings for the vehicle
including:
.Gross Combined Weight Rating (GCWR)
.Gross Vehicle Weight Rating (GVWR)
.Maximum Trailer Weight Rating
.Gross Axle Weight Rating-Rear (GAWR-RR)
.Maximum Trailer Tongue Weight Rating
See “Weight-Distributing Hitch Adjustment”
under Towing Equipment 0256 to
determine if equalizer bars are required to
obtain the maximum trailer weight rating.
See “Trailer Brakes” underTowing
Equipment 0256 to determine if brakes are
required based on the trailer weight.
The only way to be sure the weight is not
exceeding any of these ratings is to weigh
the tow vehicle and trailer combination,
fully loaded for the trip, getting individual
weights for each of these items.

{Warning
You and others could be seriously injured
or killed if the trailer is too heavy or the
trailer brakes are inadequate for the load.
The vehicle may be damaged, and the
repairs would not be covered by the
vehicle warranty.
Only tow a trailer if all the steps in this
section have been followed. Ask your
dealer for advice and information about
towing a trailer.
Gross Combined Weight Rating (GCWR)
GCWR is the total allowable weight of the
completely loaded vehicle and trailer
including any fuel, passengers, cargo,
equipment, and accessories. Do not exceed
the GCWR for your vehicle. The GCWR for
the vehicle is on the Tow Rating Chart
following.
Gross Vehicle Weight Rating (GVWR)
For information about the vehicle's
maximum load capacity, seeVehicle Load
Limits 0170. When calculating the GVWR
with a trailer attached, the trailer tongue
weight must be included as part of the
weight the vehicle is carrying.
Maximum Trailer Weight
The maximum trailer weight rating is
calculated assuming the tow vehicle has a
driver, a front seat passenger, and all
required trailering equipment. This value
represents the heaviest trailer the vehicle
can tow, but it may be necessary to reduce
the trailer weight to stay within the GCW,
GVWR, maximum trailer tongue load,
or GAWR-RR for the vehicle.
Use the tow rating chart to determine how
much the trailer can weigh, based on the
vehicle model and options.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17180837) - 2024 - CRC - 2/28/23
256 Driving and Operating
The trailer tongue weight (1) should be 10%
of the total loaded trailer weight (2). Some
specific trailer types, such as boat trailers,
fall outside of this range. Always refer to
the trailer owner’s manual for the
recommended trailer tongue weight for each
trailer. Never exceed the maximum loads for
your vehicle, hitch and trailer.
The trailer load balance percentage is
calculated as: weight (1) divided by
weight (2) times 100.
After loading the trailer, separately weigh
the trailer and then the trailer tongue to see
if the weights are appropriate for your
vehicle. If the trailer weight is too high, it
may be possible to transfer some of the
cargo into your vehicle. If the trailer tongueweight is too high or too low, it may be
possible to rearrange some of the cargo
inside of the trailer.
Do not exceed the maximum allowable
tongue weight for your vehicle. Use the
shortest hitch extension available to position
the hitch ball closer to your vehicle. This will
help reduce the effect of the trailer tongue
weight on the trailer hitch and the rear axle.
If a cargo carrier is used in the trailer hitch
receiver, choose a carrier that positions the
load as close to the vehicle as possible.
Make sure the total weight, including the
carrier, is no more than half of the
maximum allowable tongue weight for the
vehicle or 227 kg (500 lb), whichever is less.
Ask your dealer for trailering information or
assistance.
Rear Gross Axle Weight Rating
(GAWR-RR)
The GAWR-RR is the total weight that can be
supported by the rear axle of the vehicle. Do
not exceed the GAWR-RR for the vehicle,
with the tow vehicle and trailer fully loaded
for the trip including the weight of the
trailer tongue. If using a weight-distributing
hitch, do not exceed the GAWR-RR before
applying the weight distribution spring bars.
For additional assistance with trailering or
additional information, see your dealer.
Towing Equipment
Hitches
Always use the correct hitch equipment for
your vehicle. Crosswinds, large trucks going
by, and rough roads can affect the trailer
and the hitch.
Proper hitch equipment for your vehicle
helps maintain control of the vehicle-trailer
combination. Many trailers can be towed
using a weight-carrying hitch which has a
coupler latched to the hitch ball, or a tow
eye latched to a pintle hook. Other trailers
may require a weight-distributing hitch that
uses spring bars to distribute the trailer
tongue weight between your vehicle and
trailer axles. See
“Maximum Trailer Tongue
Weight” underTrailer Towing 0253 for
weight limits with various hitch types.
Never attach rental hitches or other
bumper-type hitches. Only use
frame-mounted hitches that do not attach to
the bumper.
