Lane Keep Assist
(LKA) Light
Base LevelUplevel
If equipped, the Lane Keep
Assist Light may display the
following colors:
.Blank: LKA is disabled.
.White: Appears when the
vehicle starts. A steady
white light indicates that
LKA is not ready to assist.
.Green: Appears when LKA is
turned on and ready to

the steering wheel if the
vehicle approaches a
detected lane marking.
.Amber: Appears when LKA is
active. The light flashes
amber as a Lane Departure
Warning (LDW) alert to
indicate that the lane
marking has been
unintentionally crossed.
If the system detects you
are steering intentionally (to
pass or change lanes), the
LDW alert may not display.
LKA will not assist or alert if
the turn signal is active in the
direction of lane departure,
or if LKA detects that you are
accelerating, braking,
or actively steering. See Lane
Keep Assist (LKA) 0351.

236 Driving and Operating
Average driver reaction time is
about three-quarters of a
second. In that time, a vehicle
moving at 100 km/h (60 mph)
travels 20 m (66 ft), which
could be a lot of distance in an
emergency.
Helpful braking tips to keep in
mind include:
.Keep enough distance
between you and the vehicle
in front of you.
.Avoid needless heavy
braking.
.Keep pace with traffic.
If the engine ever stops or a
brake fault occurs, the brakes
may lose power assist. More
effort will be required to stop
the vehicle and it can take
longer to stop.
Steering
Caution
To avoid damage to the
steering system, do not
drive over curbs, parking
barriers, or similar objects at
speeds greater than 3 km/h
(1 mph). Use care when
driving over other objects
such as lane dividers and
speed bumps. Damage
caused by misuse of the
vehicle is not covered by the
vehicle warranty.
Electric Power Steering
The vehicle is equipped with
an electric power steering
system, which reduces the
amount of effort needed to
steer the vehicle. It does not
have power steering fluid.
Regular maintenance is not
required.
If the vehicle experiences a
system malfunction and loses
power steering, greater
steering effort may be
required. Power steering
assist also may be reduced if
you turn the steering wheel as
far as it can turn and hold it
there with force for an
extended period of time.
See your dealer if there is a
problem.
Curve Tips
.Take curves at a reasonable
speed.
.Reduce speed before
entering a curve.

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -
2023 - CRC - 5/10/22
238 Driving and Operating
If the vehicle starts to slide,
follow these suggestions:
.Ease your foot off the
accelerator pedal and steer
the way you want the vehicle
to go. The vehicle may
straighten out. Be ready for
a second skid if it occurs.
.Slow down and adjust your
driving according to weather
conditions. Stopping
distance can be longer and
vehicle control can be
affected when traction is
reduced by water, snow, ice,
gravel, or other material on
the road. Learn to recognize
warning clues—such as
enough water, ice, or packed
snow on the road to make a
mirrored surface —and slow
down when you have any
doubt.
.Try to avoid sudden
steering, acceleration,
or braking, including
reducing vehicle speed by
shifting to a lower gear. Any
sudden changes could cause
the tires to slide. Remember: Antilock brakes
help avoid only the
braking skid.
Track Events and
Competitive Driving
(V-Series and
V-Series Blackwing)
Before any track event, there
are three features that should
be turned off:
.Automatic Emergency
Braking (AEB). See
Automatic Emergency
Braking (AEB)
0345.
.Lane Keep Assist. See Lane
Keep Assist (LKA) 0351.
.Adaptive Cruise Control. See
Adaptive Cruise Control
(Advanced) 0304.
{Danger
High-performance features
are intended for use only on
closed tracks by
experienced and qualified

drivers and should not be
used on public roads.
High-speed driving,
aggressive cornering, hard
braking, and other
high-performance driving
can be dangerous. Improper
driver inputs for the
conditions may result in loss
of control of the vehicle,
which could injure or kill you
or others. Always drive
safely.
Track events and competitive
driving may affect the vehicle
warranty. See the warranty
manual before using the
vehicle for competitive driving.
{Warning
Some of the adjustments
and procedures specified in
this section may require
specialized skill, training, and
equipment. Failure to (Continued)

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-16500442) -

Driving and Operating 253
.Shift to a lower gear when
going down steep or long
hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill
slope can cause brake
overheating, can reduce
brake performance, and
could result in a loss of
braking. Shift the
transmission to a lower gear
to let the engine assist the
brakes on a steep downhill
slope.
{Warning
Coasting downhill in
N (Neutral) or with the
ignition off is dangerous.
This can cause overheating
of the brakes and loss of
steering assist. Always have
the engine running and the
vehicle in gear.
.Drive at speeds that keep
the vehicle in its own lane.
Do not swing wide or cross
the center line.
.Be alert on top of hills;
something could be in your
lane (e.g., stalled car, crash).
.Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or IceCaution
To avoid damage to the
wheels and brake
components, always clear
snow and ice from inside the
wheels and underneath the
vehicle before driving.
Snow or ice between the tires
and the road creates less
traction or grip, so drive
carefully. Wet ice can occur at
about 0 °C (32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in
freezing rain until roads can be
treated.
For Slippery Road Driving:
.Accelerate gently.
Accelerating too quickly
causes the wheels to spin
and makes the surface under
the tires slick.
.Turn on Traction Control.
See Traction Control/
Electronic Stability Control
0
290.
.The Antilock Brake System
(ABS) improves vehicle
stability during hard stops,
but the brakes should be
applied sooner than when on
dry pavement. See Antilock
Brake System (ABS) 0286.
.Allow greater following
distance and watch for
slippery spots. Icy patches
can occur on otherwise clear
roads in shaded areas. The
surface of a curve or an
overpass can remain icy
when the surrounding roads
