sensing and diagnostic module, and
airbag wiring along with the proper
replacement procedures.
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). SeePassenger Sensing
System 061.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0384 for additional important
information. If the vehicle must be modified
because you have a disability and have
questions about whether the
modifications will affect the vehicle's
airbag system, or if you have
questions about whether the airbag
system will be affected if the vehicle is
modified for any other reason, call
Customer Assistance. See
Customer
Assistance Offices 0433.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See Airbag
Readiness Light 0105.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag may
not work properly. Do not open or
break the airbag coverings. If there
are any opened or broken airbag
coverings, have the airbag covering
and/or airbag module replaced. For
the location of the airbags, see
Where Are the Airbags? 057. See
your dealer for service.
Replacing Airbag System
Parts after a Crash
{Warning
A crash can damage the airbag
systems in the vehicle. A damaged
airbag system may not properly
protect you and your passenger(s)
in a crash, resulting in serious
injury or even death. To help make
sure the airbag systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.
If an airbag inflates, you will need to
replace airbag system parts. See your
dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See
Airbag Readiness Light 0105.

114 INSTRUMENTS AND CONTROLS
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the vehicle is
started. It provides information about
tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of the
tires are significantly underinflated.
A Driver Information Center (DIC) tire
pressure message may also display.
Stop as soon as possible, and inflate
the tires to the pressure value shown
on the Tire and Loading Information
label. SeeTire Pressure 0374.
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the problem is not corrected, the light will
come on at every ignition cycle. See
Tire Pressure Monitor Operation
0377.
Engine Oil Pressure Light
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check the
oil level as soon as possible. Add oil
if required, but if the oil level is
within the operating range and the
oil pressure is still low, have the
vehicle serviced. Always follow the
maintenance schedule for changing
engine oil.
This light should come on briefly as
the engine is started. If it does not
come on, have the vehicle serviced by
your dealer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle could
be low on oil and might have some
other system problem. See your dealer.
Low Fuel Warning Light
A Low Fuel Warning Light near the
fuel gauge comes on briefly when the
ignition is turned on as a check to
show it is working.
It also comes on when the fuel gauge
indicator nears empty. The light turns
off when fuel is added. If it does not,
have the vehicle serviced.

226 DRIVING AND OPERATING
Caution
Brake 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. From a stop, accelerate as rapidly as possible without activating
traction control to a speed of 100
km/h (60 mph).
2. Using the G-Force Gauge in 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.

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

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-15268585) -
2022 - CRC - 10/11/21
DRIVING AND OPERATING 227
that will increase the tire pressures by
35 kPa (5 psi). After this, immediately
let the tires cool to cold pressures.
Tire Inflation Pressure High Speed
SeeTire Pressure for High-Speed
Operation 0375.
Tire Inflation Pressure for Track
Driving
For driving on a race course, if the
vehicle is equipped with 275/35ZR19
(100Y) and 305/30ZR19 (102Y) tires,
set the cold (stationary) tire pressures
to 28 psi. During track sessions, set
the tire pressures at 35 to 38 psi for
hot tires. If pressures exceed 38 psi,
adjust the pressures down to 35 to
38 psi. Return the tires to the
recommended cold tire inflation
pressure when track driving has
ended.
Driving and Operating
{Warning
Operating the vehicle at high speeds
can be dangerous. Improper tire
inflation pressure can put (Continued)
Warning (Continued)
additional strain on the tires and
can cause a sudden failure. Make
sure the tires are in excellent
condition, and use the correct cold
tire inflation pressure for the
vehicle load and track/course.
{Warning
Tracks/courses put high loads on
tires operating at high speed, which
can lead to tire failure if not
inflated properly. Always limit
vehicle cargo to the driver plus one
passenger with no additional cargo.
{Warning
Track/course loads wear tires both
on the tread and internal to the
tire. When driven in track/course
conditions, even if tread is not worn
down to the treadwear indicator,
tires must be replaced after the
equivalent of two tanks of fuel or
approximately 160 km (100 mi).
Custom Launch Control (If
Equipped)
Custom Launch Control allows the
following parameters for Launch
Control to be modified:
.Launch RPM
.Slip Target (5%–15%)
.Surface Type
To adjust the Launch RPM, all of
these conditions must be met:
.The vehicle must be in Track Mode.
See “Track Mode ”under Driver Mode
Control 0259.
.Performance Traction Management
(PTM) Mode must be enabled. See
Driver Mode Control 0259.
.The steering wheel must be straight.
.The driver door must be closed.
.The transmission must be in D
(Drive) or forward gear.
.The parking brake must not be
engaged.
For more information on Competitive
Driving Mode, see Competitive Driving
Mode 0265.

DRIVING AND OPERATING 231
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment
in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper tread
depth. SeeTires0367.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving on
flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.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 Ice
Caution
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.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-15268585) -
2022 - CRC - 10/11/21
234 DRIVING AND OPERATING
A vehicle-specific Tire and
Loading Information label is
attached to the vehicle's center
pillar (B-pillar). The Tire and
Loading Information label shows
the number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading Information
label also shows the tire size of
the original equipment tires (3)
and the recommended cold tire
inflation pressures (4). For more
information on tires and inflation
seeTires 0367 and
Tire Pressure 0374.
There is also important loading
information on the Certification
label. It may show the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight Rating
(GAWR) for the front and rear
axle. See “Certification Label” later
in this section. “Steps for Determining Correct
Load Limit–
1.Locate the statement "The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs." on your
vehicle’s placard.
2.Determine the combined weight
of the driver and passengers
that will be riding in your
vehicle.
3.Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the "XXX" amount
equals 1400 lbs. and there will
be five 150 lb passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) = 650 lbs.)
5.Determine the combined weight
of luggage and cargo being
loaded on the vehicle. That
weight may not safely exceed
the available cargo and luggage
load capacity calculated in
Step 4.
6.If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your
vehicle. Consult this manual to
determine how this reduces the
available cargo and luggage
load capacity of your vehicle.”
See Trailer Towing (LSY 2.0L L4 and
LGY 3.0L V6 Engines Only) 0323
for important information on
towing a trailer, towing safety
rules, and trailering tips.

2022 - CRC - 10/11/21
DRIVING AND OPERATING 325
Ask your dealer for trailering
information or assistance.
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.
Never attach rental hitches or other
bumper-type hitches. Only use
frame-mounted hitches that do not
attach to the bumper.
Always seal any holes in your vehicle
if the trailer hitch removed. If not
sealed, dirt, water, and carbon
monoxide (CO) from the exhaust may
enter your vehicle. SeeEngine Exhaust
0 245.
Consider using mechanical sway
controls with any trailer. Ask a
trailering professional about sway
controls or refer to the trailer
manufacturer's recommendations and
instructions.
Tires
.Do not tow a trailer while using a
compact spare tire on the vehicle.
.Tires must be properly inflated to
support loads while towing a trailer.
See Tires 0367 for instructions on
proper tire inflation.
Safety Chains
Always attach chains between the
vehicle and the trailer, and attach the
chains to the holes on the trailer hitch
platform. Instructions about safety
chains may be provided by the hitch
manufacturer or by the trailer
manufacturer.
Cross the safety chains under the
tongue of the trailer to help prevent
the tongue from contacting the road if
it becomes separated from the hitch.
Always leave just enough slack so the
combination can turn. Never allow
safety chains to drag on the ground.
Trailer Brakes
Loaded trailers over 450 kg (1,000 lb)
must be equipped with brake systems
and with brakes for each axle. Trailer
braking equipment conforming to Canadian Standards Association (CSA)
requirement CAN3-D313, or its
equivalent, is recommended.
State or local regulations may require
trailers to have their own braking
system if the loaded weight of the
trailer exceeds certain minimums that
can vary from state to state. Read and
follow the instructions for the trailer
brakes so they are installed, adjusted,
and maintained properly. Never
attempt to tap into your vehicle's
hydraulic brake system. If you do,
both the vehicle anti-lock brakes and
the trailer brakes may not function,
which could result in a crash.
Turn Signals When Towing a
Trailer
When properly connected, the trailer
turn signals will illuminate to indicate
the vehicle is turning, changing lanes,
or stopping. When towing a trailer,
the arrows on the instrument cluster
will illuminate even if the trailer is not
properly connected or the bulbs are
burned out.

Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer. See the
warranty manual for information
regarding the tire warranty and
where to get service. For
additional information refer to the
tire manufacturer.
{Warning
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a result
of too much flexing. There
could be a blowout and a
serious crash. SeeVehicle
Load Limits 0233.
.Underinflated tires pose the
same danger as overloaded
tires. The resulting crash
(Continued)
Warning (Continued)
could cause serious injury.
Check all tires frequently to
maintain the recommended
pressure. Tire pressure should
be checked when the tires
are cold.
.Overinflated tires are more
likely to be cut, punctured,
or broken by a sudden impact
— such as when hitting a
pothole. Keep tires at the
recommended pressure.
.Worn or old tires can cause a
crash. If the tread is badly
worn, replace them.
.Replace any tires that have
been damaged by impacts
with potholes, curbs, etc.
.Improperly repaired tires can
cause a crash. Only your
dealer or an authorized tire
(Continued)
Warning (Continued)
service center should repair,
replace, dismount, and mount
the tires.
.Do not spin the tires in
excess of 56 km/h (35 mph)
on slippery surfaces such as
snow, mud, ice, etc. Excessive
spinning may cause the tires
to explode.
See Tire Pressure for High-Speed
Operation 0375 for inflation
pressure adjustment for
high-speed driving.
All-Season Tires
This vehicle may come with all-season
tires. These tires are designed to
provide good overall performance on
most road surfaces and weather
conditions. Original equipment tires
designed to GM's specific tire
performance criteria have a TPC
specification code molded onto the
sidewall. Original equipment
