In addition, the vehicle has a
passenger sensing system for
the front outboard passenger
position, which includes
sensors that are part of the
passenger seat. The
passenger sensing system
may not operate properly if
the original seat trim is
replaced with non-GM covers,
upholstery, or trim; or with GM
covers, upholstery, or trim
designed for a different
vehicle. Any object, such as an
aftermarket seat heater or a
comfort-enhancing pad or
device, installed under or on
top of the seat fabric, could
also interfere with the
operation of the passenger
sensing system. This could
either prevent proper
deployment of the passenger
airbag(s) or prevent the
passenger sensing system
from properly turning off the
passenger airbag(s). See
Passenger Sensing System

.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

.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.

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)

2. Using the G-Force Gaugein the HUD display, use
enough pedal force to
completely stop the vehicle
in four to five seconds.
(~0.7g Decel level to stop
the vehicle in a straight
line). If ABS activates,
braking is too hard.
3. Repeat the first two steps 20 consecutive times, this
should take about
five minutes.
4. After completing the 20 stops, cool the brakes by
driving for 8 km (5 mi) at
100 km/h (60 mph).
Alternative Closed Course
Brake Burnishing Procedure
This brake burnish procedure
should only be run on vehicles
with a factory equipped brake
system.
This procedure should only be
run on a track and only on dry
pavement. Brake pedal fade
will occur during this track
burnish procedure and can cause brake pedal travel and
force to increase. This could
extend stopping distance until
the brakes are fully burnished.
1. Start track lapping at lower speeds and lower
braking efforts for
three minutes of driving.
Allow for increased braking
distances due to reduced
brake output.
2. After Step 1, increase speed and braking effort
for the next six minutes of
lapping, gradually ending
up at 90% effort. Continue
to allow for increased
braking distance due to
reduced brake output.
3. Cool the brakes by lapping with minimal light braking
for six minutes.
Wheel Alignment

Tire Inflation Pressure
Guidelines
Tire inflation pressures affect
vehicle handling and tire life,
and should be adjusted for
various types of tracks/
courses.
Inspect the tires prior to every
track/course session. Track/
course driving will reduce the
tire tread life.
To maximize tire life, drive
800 km (500 mi) prior to
racetrack driving or complete
the minimum track running
that will increase the tire
pressures by 35 kPa (5 psi).
After this, immediately let the
tires cool to cold pressures.
