To recalibrate the vehicle's position on
the map, park with the vehicle
running for two to five minutes, until
the vehicle position updates. Make
sure the vehicle is parked in a location
that is safe and has a clear view of the
sky and away from large obstructions.
If the System Needs
Service
If the navigation system needs service,
see your dealer.
Map Data Updates
The map data in the vehicle is the
most up-to-date information available
when the vehicle was produced.
See www.gmnavdisc.com for details on
ordering, purchasing, and installing a
new or replacement SD card. Features
are subject to change. For more
information on this feature, see
my.cadillac.com/learn.
Database Coverage
Explanations
Coverage areas vary with respect to
the level of map detail available for
any given area. Some areas feature
greater levels of detail than others.
If this happens, it does not mean
there is a problem with the system. As
the map data is updated, more detail
can become available for areas that
previously had limited detail. SeeMap
Data Updates 0163.
Voice Recognition
If equipped, voice recognition allows
for hands-free operation within the
navigation, audio, phone, and weather
applications. This feature can be
started by pressing
gon the steering
wheel or touching
gon the
infotainment display.
However, not all features within these
areas are supported by voice
commands. Generally, only complex
tasks that require multiple manual
interactions to complete are
supported by voice commands. For example, tasks that take more
than one or two touches, such as a
song or artist to play from a media
device, would be supported by voice
commands. Other tasks, like adjusting
the volume or seeking up or down, are
audio features that are easily
performed by touching one or two
options, and are not supported by
voice commands.
In general there are flexible ways to
speak commands for completing the
tasks.
If your language supports it, try
stating a one-shot command, such as
“Directions to address <number, street,
city, state/province>.”
Do not include
the ZIP code while stating the address
during the command. Another
example of a one-shot Destination
Entry command is, “Directions to
Place of Interest at <hotel>.” If these
commands do not work, try saying,
“Take me to Place of Interest ”or “Find
address ”and the system will walk you
through by asking additional
questions.

Driving 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.
.Keep vehicle tires properly inflated.
.Combine several trips into a
single trip.
.Replace the vehicle&#39;s tires with the
same TPC Spec number molded into
the tire&#39;s sidewall near the size.
.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.

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-14584335) -
2021 - CRC - 12/4/20
206 DRIVING AND OPERATING
.The Antilock Brake System (ABS)
allows steering while braking.
Off-Road Recovery
The vehicle&#39;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&#39;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.
.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.
