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
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)

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
260 Driving and Operating
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
(Continued)
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.”

holding the vehicle. See
Automatic Vehicle Hold (AVH)
Light0129.
Ride Control
Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction
Control System (TCS) and
StabiliTrak/Electronic Stability
Control (ESC). These systems
help limit wheel slip and assist
the driver in maintaining
control, especially on slippery
road conditions.
TCS activates if it senses that
any of the drive wheels are
spinning or beginning to lose
traction. When this happens,
the system brakes the
spinning wheel(s) and/or
reduces engine power to limit
wheel spin. StabiliTrak/ESC activates
when the computer senses a
difference between the
intended path and the
direction the vehicle is actually
traveling. StabiliTrak/ESC
selectively applies braking
pressure at any one of the
vehicle's brakes to help steer
the vehicle in the intended
direction.
If cruise control is being used
and TCS or StabiliTrak/ESC
begins to limit wheel spin,
cruise control will disengage.
Cruise control may be turned
back on when road conditions
allow.
Both systems come on
automatically when the vehicle
is started and begins to move.
The systems may be heard or
felt while they are operating
or while performing diagnostic
checks. This is normal and
does not mean there is a
problem with the vehicle.
It is recommended to leave
both systems on for normal
driving conditions, but it may
be necessary to turn TCS off
if the vehicle gets stuck in
sand, mud, ice, or snow. See If
the Vehicle Is Stuck
0261 and
“Turning the Systems Off and
On” later in this section.
The indicator light for both
systems is in the instrument
cluster. This light will:
.Flash when TCS is limiting
wheel spin.
.Flash when StabiliTrak/ESC
is activated.
.Turn on and stay on when
either system is not working.

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

302 Driving and Operating
Launch Control will initially
limit engine speed as you
rapidly apply the accelerator
pedal to wide open throttle.
Allow the engine rpm to
stabilize. A smooth, quick
release of the brake pedal,
while maintaining the fully
pressed accelerator pedal, will
manage wheel slip.
After the vehicle is launched,
the system continues in
Competitive Driving Mode
or PTM.
Competitive Driving Mode,
PTM, and Launch Control are
systems designed for a closed
course race track and not
intended for public roads. The
systems are not intended to
compensate for lack of driver
experience or familiarity with
the race track.Limited-Slip
Differential
If equipped, the Electronic
Limited-Slip Differential (eLSD)
is automatically activated.
eLSD actively monitors vehicle
sensors and driver inputs to
determine the amount of
change for the conditions.
With eLSD, the vehicle has:
.Enhanced high-speed
control.
.Improved traction through
corners, allowing more
acceleration.
.More precise steering.
.Increased vehicle agility.
.Integration with StabiliTrak/
Electronic Stability
Control (ESC).
For vehicles with eLSD, driven
under severe conditions, the
rear axle fluid should be
changed. See Competitive
Driving Mode 0299 and
Maintenance Schedule 0471.
Cruise Control
{
Warning
Cruise control can be
dangerous where you
cannot drive safely at a
steady speed. Do not use
cruise control on winding
roads or in heavy traffic.
Cruise control can be
dangerous on slippery roads.
On such roads, fast changes
in tire traction can cause
excessive wheel slip, and
you could lose control. Do
not use cruise control on
slippery roads.
With cruise control, a speed of
about 40 km/h (25 mph) or
more can be maintained
without keeping your foot on
the accelerator. Cruise control
does not work at speeds
below about 40 km/h (25 mph).
If equipped with a manual
transmission, the cruise
control will remain active when

Cadillac CT5 Owner Manual (GMNA-Localizing-U.S./Canada-16500419) -
2023 - CRC - 5/10/22
Driving and Operating 303
the gears are shifted. The
cruise is disengaged if the
clutch is pressed for several
seconds.
If the Traction Control/
StabiliTrak/Electronic Stability
Control (ESC) system begins
to limit wheel spin while using
cruise control, the cruise
control automatically
disengages. See Traction
Control/Electronic Stability
Control0291. If a collision
alert occurs when cruise
control is activated, cruise
control is disengaged. See
Forward Collision Alert (FCA)
System 0346. When road
conditions allow cruise control
to be safely used, it can be
turned back on.
Cruise control will disengage if
either TCS or StabiliTrak/ESC
is turned off.
If the brakes are applied,
cruise control disengages.

Passing Another Vehicle
While Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed.
When you take your foot off
the pedal, the vehicle will slow
down to the previous set
cruise speed.
While pressing the accelerator
pedal or shortly following the
release to override cruise,
briefly applying SET− will
result in cruise set to the
current vehicle speed.
Using Cruise Control on Hills
How well the cruise control will
work on hills depends upon
the vehicle speed, load, and
the steepness of the hills. When going up steep hills, you
might have to step on the
accelerator pedal to maintain
your speed. When going
downhill, the cruise control
system may automatically
brake to slow the vehicle
down. Also, you may have to
brake or shift to a lower gear
to keep your speed down.
If the brake pedal is applied,
cruise control disengages.
Ending Cruise Control
There are five ways to end
cruise control:
.Step lightly on the brake
pedal.
.Press*.
.Shift the transmission to
N (Neutral).
.Press the clutch pedal for
several seconds or shift to
Neutral (manual
transmissions).
.PressJ.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
Jis
pressed or if the ignition is
turned off.
Adaptive Cruise
Control (Advanced)
If equipped, Adaptive Cruise
Control (ACC) allows the
cruise control set speed and
following gap to be selected.
Read this entire section
before using this system. The
following gap is the following
time between your vehicle and
a vehicle detected directly
ahead in your path, moving in
the same direction. If no
vehicle is detected in your
path, ACC works like regular
cruise control. ACC uses
camera and radar sensors.
See Radio Frequency
Statement 0496.
If a vehicle is detected in your
path, ACC can speed up the
vehicle or apply limited,
moderate braking to maintain
