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.

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.

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.

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

252 Driving and Operating
Brake Burnishing
New brake pads must be
burnished before racing or
other competitive driving.
Caution
These procedures are
specific to the V-Series with
performance brake linings
package. This procedure
should not be run on other
models as damage may
result.
Caution
The new vehicle break-in
period should be completed
before performing the brake
burnishing procedure or
damage may occur to the
powertrain/engine. See New
Vehicle Break-In0265.
Caution
Brake pedal fade will occur
during any track burnish
procedure and can cause
brake pedal travel and force
to increase. This could
extend stopping distance
until the brakes are fully
burnished.
When performed as
instructed, these procedures
will not damage the brakes.
During the burnishing
procedure, the brake pads will
smoke and produce an odor.
The braking force and pedal
travel may increase. After the
procedure is complete, the
brake pads may appear white
at the rotor contact.
Perform these procedures in a
safe manner and in compliance
with all local and state
ordinances/laws regarding
motor vehicle operation.
Perform the procedures only
on dry pavement. As with all high performance
brake systems, some amount
of brake squeal is normal.
Street High Performance
Brake Burnishing Procedure
This section is for the V-Series
Blackwing with J57 carbon
ceramic brake rotors only.
This procedure should only be
run on a track or other
non-public area, and only on
dry pavement.
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).

258 Driving and Operating
{Warning
Wet brakes can cause
crashes. They might not
work as well in a quick stop
and could cause pulling to
one side. You could lose
control of the vehicle.
After driving through a large
puddle of water or a car/
vehicle wash, lightly apply
the brake pedal until the
brakes work normally.
Flowing or rushing water
creates strong forces.
Driving through flowing
water could cause the
vehicle to be carried away.
If this happens, you and
other vehicle occupants
could drown. Do not ignore
police warnings and be very
cautious about trying to
drive through flowing water.
Caution
Driving through deep
puddles or standing water
can cause water to come in
through the engine air intake
and damage the engine.
If deep puddles or standing
water cannot be avoided,
proceed with caution and do
not exceed 8 km/h (5 mph).
Do not drive through water
that may come close to or
cover the vehicle’s
underbody.
Hydroplaning
Hydroplaning is dangerous.
Water can build up under the
vehicle's tires so they actually
ride on the water. This can
happen if the road is wet
enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.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. See Tires
0418.
.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.

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
Driving and Operating 259
.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(Continued)
Warning (Continued)
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 (Continued)
Caution (Continued)
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
0 291.
.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)0287.
.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
are clear. Avoid sudden
steering maneuvers and
braking while on ice.
.Turn off cruise control.
.Select All-Wheel Drive (AWD)
Mode for vehicles equipped
with AWD. Select Snow/Ice
Mode for FWD only vehicles.
See Driver Mode Control
0293 and
All-Wheel Drive 0287.
Cold Weather Mode
In very low temperatures, a
cold weather message may
display on the Driver
Information Center (DIC). The
engine speed, transmission
shift patterns, and cabin fan speed may operate differently
to enable the vehicle to warm
up quicker. You can manually
override the cabin fan speed in
cold weather mode.
Blizzard Conditions
Stop the vehicle in a safe
place and signal for help. Stay
with the vehicle unless there is
help nearby. If possible, use
Roadside Assistance. See
Roadside Assistance Program

489. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine
exhaust under the vehicle.
This may cause exhaust
gases to get inside. Engine
exhaust contains carbon
monoxide (CO), which cannot

Warning (Continued)
be seen or smelled. It can
cause unconsciousness and
even death.
If the vehicle is stuck
in snow:
.Clear snow from the base
of the vehicle, especially
any blocking the
exhaust pipe.
.Open a window about
5 cm (2 in) on the vehicle
side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the
highest setting. See
“Climate Control Systems.”
