Information
Driving for Better
Fuel Economy
Driving habits can affect fuel
mileage. Here are some driving
tips to get the best fuel
economy possible:
.Set the climate controls to
the desired temperature
after the engine is started,
or turn them off when not
required.
.Avoid fast starts and
accelerate smoothly.
.Brake gradually and avoid
abrupt stops.
.Avoid idling the engine for
long periods of time.
.When road and weather
conditions are appropriate,
use cruise control.
.Always follow posted speed
limits or drive more slowly
when conditions require.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
242 Driving and Operating
.Keep vehicle tires properly
inflated.
.Combine several trips into a
single trip.
.Replace the vehicle's tires
with the same TPC Spec
number molded into the
tire's sidewall near the size.
.Follow recommended
scheduled maintenance.
Distracted Driving
Distraction comes in many
forms and can take your focus
from the task of driving.
Exercise good judgment and
do not let other activities
divert your attention away
from the road. Many local
governments have enacted
laws regarding driver
distraction. Become familiar
with the local laws in
your area.
To avoid distracted driving,
keep your eyes on the road,
keep your hands on the
steering wheel, and focus your
attention on driving.
.Do not use a phone in
demanding driving situations.
Use a hands-free method to
place or receive necessary
phone calls.
.Watch the road. Do not read,
take notes, or look up
information on phones or
other electronic devices.
.Designate a front seat
passenger to handle
potential distractions.
.Become familiar with vehicle
features before driving, such
as programming favorite
radio stations and adjusting
climate control and seat
settings. Program all trip
information into any
navigation device prior to
driving.
.Wait until the vehicle is
parked to retrieve items that
have fallen to the floor.
.Stop or park the vehicle to
tend to children.
.Keep pets in an appropriate
carrier or restraint.
.Avoid stressful
conversations while driving,
whether with a passenger or
on a cell phone.
{Warning
Taking your eyes off the
road too long or too often
could cause a crash
resulting in injury or death.
Focus your attention on
driving.
Refer to the infotainment
section for more information
on using that system and the
navigation system, if equipped,
including pairing and using a
cell phone.
Defensive Driving
Defensive driving means
“always expect the
unexpected.” The first step in
driving defensively is to wear
the seat belt. See Seat Belts
0 55.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
Driving and Operating 243
.Assume that other road
users (pedestrians,
bicyclists, and other drivers)
are going to be careless and
make mistakes. Anticipate
what they may do and be
ready.
.Allow enough following
distance between you and
the driver in front of you.
.Focus on the task of driving.
Impaired Driving
Death and injury associated
with impaired driving is a
global tragedy.
{Warning
Drinking alcohol or taking
drugs and then driving is
very dangerous. Your
reflexes, perceptions,
attentiveness, and judgment
can be affected by even a
small amount of alcohol or
drugs. You can have a(Continued)
Warning (Continued)
serious—or even fatal —
collision if you drive after
drinking or taking drugs.
Do not drive while under the
influence of alcohol or drugs,
or ride with a driver who has
been drinking or is impaired
by drugs. Find alternate
transportation home; or if
you are with a group,
designate a driver who will
remain sober.
Control of a Vehicle
Braking, steering, and
accelerating are important
factors in helping to control a
vehicle while driving.
Braking
Braking action involves
perception time and reaction
time. Deciding to push the
brake pedal is perception time.
Actually doing it is
reaction time. 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.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
244 Driving and Operating
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.
Variable Effort Steering
The vehicle has a steering
system that varies the amount
of effort required to steer the
vehicle in relation to the speed
of the vehicle.
The amount of steering effort
required is less at slower
speeds to make the vehicle
more maneuverable and easier
to park. At faster speeds, the
steering effort increases to
provide a sport-like feel to the
steering. This provides
maximum control and stability.
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 berequired. 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.
.Maintain a reasonable
steady speed through the
curve.
.Wait until the vehicle is out
of the curve before
accelerating gently into the
straightaway.
Steering in Emergencies
.There are some situations
when steering around a
problem may be more
effective than braking.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
Driving and Operating 245
.Holding both sides of the
steering wheel allows you to
turn 180 degrees without
removing a hand.
.Antilock Brake System (ABS)
allows steering while
braking.
Off-Road Recovery
The vehicle's right wheels can
drop off the edge of a road
onto the shoulder while
driving. Follow these tips:1. Ease off the accelerator and then, if there is
nothing in the way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn,
until the right front tire
contacts the
pavement edge.
3. Turn the steering wheel to go straight down the
roadway.
Loss of Control
Skidding
There are three types of skids
that correspond to the
vehicle's three control
systems:
.Braking Skid —wheels are
not rolling.
.Steering or Cornering Skid —
too much speed or steering
in a curve causes tires to slip
and lose cornering force.
.Acceleration Skid —too
much throttle causes the
driving wheels to spin. Defensive drivers avoid most
skids by taking reasonable
care suited to existing
conditions, and by not
overdriving those conditions.
But skids are always possible.
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.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
246 Driving and Operating
.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) 0349.
.Lane Keep Assist. See Lane
Keep Assist (LKA) 0356.
.Adaptive Cruise Control. See
Adaptive Cruise Control
(Advanced) 0305.
{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
perform these procedures
properly could cause
malfunction, potentially
resulting in death, personal
injury, or damage to the
vehicle or property. Do not
attempt to perform these
adjustments or procedures
unless properly qualified.
{Warning
Prior to each track event
and again before returning
to public roads, tighten the
wheel nuts with a torque
wrench to the proper torque
specification. Wheel nuts
that are improperly or
incorrectly tightened can (Continued)

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -

Driving and Operating 247
Warning (Continued)
cause the wheels to become
loose or come off, resulting
in a crash. See Capacities
and Specifications0482 for
wheel nut torque
specifications.
Caution
If the vehicle is used for
track events and
competitive driving, the
engine may use more oil
than it would with normal
use. Low oil levels can
damage the engine. Check
the oil level often and
maintain the proper level.
See Engine Oil 0383.
Competitive Driving Mode can
be selected. See Driver Mode
Control 0293.
Seat Belts
Lap-Shoulder Belt
If equipped, the driver seat
belt has an Automatic Locking
Retractor (ALR). This feature
is useful in performance
driving scenarios where the
driver wants to be held in the
seat more tightly to take
advantage of the aggressive
bolstering of the seat.
1. Move the seat 8-10 cm (3-4 in) rearward from the
normal driving position.
2. Pull the driver shoulder belt out as far as it will go,
until it stops, to set the
lock. While holding the
shoulder belt in this
position, buckle the belt.
When the shoulder belt is
released, the retractor will
make a ratchet sound
when it retracts. When the
retractor lock is set, the
belt can be tightened but
not pulled out of the
retractor. 3. Adjust the belt, and then
move the seat forward
8-10 cm (3-4 in) to the
desired driving position.
This will secure the belt.
The belt fit should be tight,
but not uncomfortable.
To unlatch the belt, press
the button on the buckle.
The belt should return to
its stowed position.
Axle Fluid
Axles must have 2 400 km
(1,500 mi) before being used in
track driving.
The front, if equipped with
AWD, and rear axle fluid
temperatures may be higher
than when driving in severe
conditions. Drain and refill with
new fluid after the first racing
or competitive driving event,
and then after every 24 hours
of racing or competitive
driving. See your dealer for
the correct fluid.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
248 Driving and Operating
Caution
During a first time track or
racing event, high axle
temperatures can occur.
Damage could be caused to
the axle and would not be
covered by the vehicle
warranty. Do not drive as
long or as fast the first time
the vehicle is driven on the
track or raced.
.The axle lubricant should be
replaced with new lubricant.
.On vehicles without a
differential cooler, additional
cooling capacity is required
for continuous competitive
driving. The V-Series
Blackwing has a differential
cooler, so no additional
cooling capacity is
necessary.
Engine OilCaution
If the vehicle is used for
track events and
competitive driving, the
engine may use more oil
than it would with normal
use. Low oil levels can
damage the engine. Check
the oil level often and
maintain the proper level.
See Engine Oil 0383.
Check the oil level often during
track events and competitive
driving, and keep the oil level
at or near the upper mark. See
“Checking the Engine Oil" in
Engine Oil 0383.
Fuel
Use premium unleaded
gasoline with a posted octane
rating of 93 at a track event.
Unleaded gasoline with a
posted octane rating of 91 may be used, but
performance will be degraded.
See Prohibited Fuels
0361.
Automatic or Manual
Transmission Fluid
Have the transmission fluid
set to the track specific oil
level prior to track usage.
Transmission fluid should be
changed after every 15 hours
of track usage. Any
transmission level set or
change should be performed
at the dealer.
Brakes
Battery Disconnect
Disconnect the battery before
servicing the hydraulic brake
system. It is critical to
disconnect the battery before
bleeding the system, replacing
the pads, or any other work.
The battery must be
disconnected to prevent the
brake master cylinder from
pressurizing the hydraulic
system during its automated

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
Driving and Operating 249
self diagnostic tests that may
occur when a door is opened
or the remote key is present.
{Warning
To avoid personal injury and/
or vehicle damage, always
disconnect the battery
before performing service
work on the hydraulic brake
system. Bleeding the brake
system with the battery
connected can lead to
excessive pressurization of
the system during automatic
diagnostic tests or diagnosis
of a leak or air in the braking
system. A Diagnostic
Trouble Code (DTC) may set
and vehicle speed may be
limited.Brake Cooling (V-Series
Blackwing)
Prior to any track event, high
speed driving event,
or competitive driving,
complete the following:
1. Ensure all the brake cooling parts are correctly
secured and installed.
2. Inspect and replace any deflectors that have
damage.
3. Inspect for blockage in the front brake cooling duct
prior to every event.
4. Remove front tire deflector (if equipped).
If improved brake cooling is
desired on vehicles with
cast-iron brakes (RPO JGH),
install the ball joint protector
front shields, remove both
upper and lower rear rotor
shields, and install the rear
lower control arm cooling
deflectors, per the
instructions included with the
brake cooling kit. These parts are for track use only. After
track events, reinstall the
original front and rear rotor
shields and remove the rear
lower control arm cooling
deflectors.
