ignition is off. The lamps will not
come back on again until one of the
following occurs:
.The ignition is turned on.
.The doors are closed and then
re-opened.
Exterior Lighting Battery

INFOTAINMENT SYSTEM 165
Hybrid Speech Recognition
If equipped, this feature helps
distinguish words by using
Internet-based information along with
the system’s voice recognition
database. This allows you to speak
more naturally when using voice
recognition.
Using Voice Recognition
Voice recognition becomes available
once the system has been initialized.
This begins when the ignition is
turned on. Initialization may take a
few moments.1. Press
gon the steering wheel
controls to activate voice
recognition.
2. The audio system mutes and the system plays a prompt.
3. Clearly speak one of the commands described in this section.
A voice recognition system prompt
can be interrupted while it is
playing by pressing
gagain.
Once voice recognition is started, both
the infotainment display and
instrument cluster show the selections and visual dialog content. These
displays can be turned on or off in the
Tutorial Mode under
Settings0182.
There are three voice prompt modes
supported:
.Informative verbal prompts: This
type of prompt will provide more
information regarding the supported
actions.
.Short prompts: This type of prompt
will provide simple instructions
about what can be stated.
.Auto informative prompts: This type
of prompt plays during the first few
speech sessions, then automatically
switches to the short prompt after
some experience has been gained
through using the system.
If a command is not spoken, the voice
recognition system says a help
prompt.
Prompts and Infotainment Displays
While a voice recognition session is
active, there may be corresponding
options showing on the displays.
A selection can be made by manually
touching the option, or by speaking
the number for the option to select. Manual interaction in the voice
recognition session is permitted.
Interaction during a voice session may
be completed entirely using voice
commands while some manual
commands may expedite a task. If a
selection is made using a manual
control, the voice recognition dialog
will progress in the same way as if the
selection were made using a voice
command. Once the system completes
the task, or the session is terminated,
the voice recognition dialog stops.
An example of this type of manual
intervention is touching an entry of a
displayed number list instead of
speaking the number associated with
the entry desired.
Canceling Voice Recognition
.Touch or say
“Cancel”or“Exit ”to
terminate the voice recognition
session and show the display where
voice recognition was initiated.
.Pression the steering wheel
controls to terminate the voice
recognition session and show the
display where voice recognition was
initiated.

226 DRIVING AND OPERATING
{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 IceCaution
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.
.Turn on Traction Control. See
Traction Control/Electronic Stability
Control 0257.
.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) 0253.
See Driver Mode Control 0258.
.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.
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 Service. See Roadside
Service 0432. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside mirror.

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-15283641) -
2022 - CRC - 10/12/21
232 DRIVING AND OPERATING
Caution (Continued)
.Should the vehicle be used for
racing or competitive driving
(after break-in), the rear axle
lubricant must be replaced
beforehand.
See Track Events and Competitive
Driving (V-Series and V-Series
Blackwing) 0213.
On new vehicles, the various
mechanical and electrical systems
experience a “break-in”period during
the first 6,400 km (4,000 miles) of
routine driving. As the vehicle is
driven, the mechanical systems adjust
to provide optimal fuel economy and
transmission shift performance.
Electrical systems will adapt and
calibrate during the break-in period.
A one-time occurrence of clicks and
similar vehicle noises is normal during
this process.
Normal driving charges the vehicle’s
battery to achieve the best operation
of the vehicle, including fuel economy.
Composite Materials
This vehicle may be equipped with
parts containing carbon fiber,
sheet-molding compound, or other
composite materials. Dealer-installed
accessories may also contain
composite materials.
{Warning
Exposed edges of parts containing
carbon fiber and other composite
materials can be sharp. Contact
with these parts could result in
injury. Use caution to avoid
contacting these parts, including
when washing the vehicle. If the
parts are damaged, replace the
parts promptly with replacements
from your dealer.
{Warning
Rocker extensions may break under
pressure, resulting in property
damage or injury. Do not stand on
the rocker extension or use it as
a step.
{Warning
Rear end spoilers may break under
pressure, resulting in property
damage or injury. Do not push the
vehicle by the spoiler or use the
spoiler as a handle.
Ignition Positions
The vehicle has an electronic keyless
ignition with pushbutton start.
The Remote Key must be in the
vehicle for the system to operate.
If the pushbutton start is not working,
the vehicle may be near a strong radio

antenna signal causing interference to
the Keyless Access system. SeeRemote
Keyless Entry (RKE) System Operation
0 7.
To shift out of P (Park), the vehicle
must be on and the brake pedal must
be applied.
Stopping the Engine/OFF (No
Indicator Lights) : When the vehicle
is stopped, press ENGINE START/
STOP once to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0237.
If the vehicle has an automatic
transmission, and is not in P (Park),
the ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition system will
turn OFF.
If the vehicle has a manual
transmission and is stationary, the
ignition will turn off, and Retained Accessory Power (RAP) will remain
active. See
Retained Accessory Power
(RAP) 0237.
The vehicle may have an electric
steering column lock. The lock is
activated when the vehicle is switched
to OFF and the driver door is opened.
A sound may be heard as the lock
actuates or releases. The steering
column lock may not release with the
wheels turned off center. If this
happens, the vehicle may not start.
Move the steering wheel from left to
right while attempting to start the
vehicle. If this does not work, the
vehicle needs service.
Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake and
steering systems and disable the
airbags.
If the vehicle must be shut off in an
emergency: 1. Brake using a firm and steady pressure. Do not pump the brakes
repeatedly. This may deplete power
assist, requiring increased brake
pedal force. 2. Shift the vehicle to N (Neutral).
This can be done while the vehicle
is moving. After shifting to
N (Neutral), firmly apply the brakes
and steer the vehicle to a safe
location.
3. Come to a complete stop. Shift to P (Park) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition off.
4. Set the parking brake. See Electric
Parking Brake 0254.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the vehicle
off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
press and hold ENGINE START/STOP
for longer than two seconds, or press
twice within five seconds.
