Voltmeter Gauge (Base
Level Cluster)
Standard Theme
When the ignition is on, this gauge
indicates the battery voltage.
When the engine is running, this
gauge shows the condition of the
charging system. The gauge can
transition from a higher to lower or a
lower to higher reading. This is
normal. If the vehicle is operating
outside the normal operating range,
the charging system light comes on.
See Charging System Light 0127. Readings outside the normal operating
range can also occur when a large
number of electrical accessories are
operating in the vehicle and the
engine is left idling for an extended
period. This condition is normal since
the charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can only be driven for a
short time with the readings outside
the normal operating range. If the
vehicle must be driven, turn off all
accessories, such as the radio and air
conditioner, and unplug all chargers
and accessories.
Readings outside the normal operating
range indicate a possible problem in
the electrical system. Have the vehicle
serviced as soon as possible.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety belt reminder
light on the instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to
remind the driver to fasten their
safety belt. Then the light stays on
solid until the belt is buckled. This
cycle may continue several times if
the driver remains or becomes
unbuckled while the vehicle is moving.
If the driver safety belt is buckled,
neither the light nor the chime
comes on.

There is a passenger safety belt
reminder light near the passenger
airbag status indicator. SeePassenger
Sensing System 079.
When the vehicle is started, this light
flashes and a chime may come on to
remind passengers to fasten their
safety belt. Then the light stays on
solid until the belt is buckled. This
cycle continues several times if the
passenger remains or becomes
unbuckled while the vehicle is moving.
If the passenger safety belt is buckled,
neither the chime nor the light
comes on.
The front passenger safety belt
reminder light and chime may turn on
if an object is put on the seat such as
a briefcase, handbag, grocery bag,
laptop, or other electronic device. To turn off the reminder light and/or
chime, remove the object from the

The airbag readiness light comes on
for several seconds when the vehicle is
started. If the light does not come on
then, have it fixed immediately.
{Warning
If the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in the
vehicle might not inflate in a crash,
or they could even inflate without a
crash. To help avoid injury, have
the vehicle serviced right away.
If there is a problem with the airbag

DRIVING AND OPERATING 185
Driving Information
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. .
Become familiar with vehicle
features before driving, such as
programming favorite radio
stations and adjusting climate
control and seat settings. Program
all trip information into any
navigation device prior to driving.
. Wait until the vehicle is parked to
retrieve items that have fallen to
the floor.
. Stop or park the vehicle to tend to
children.
. Keep pets in an appropriate carrier
or restraint.
. Avoid stressful conversations
while driving, whether with a
passenger or on a cell phone.
{Warning
Taking your eyes off the road too
long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving. See the infotainment manual for
information on that system or the
navigation system, if equipped,
including pairing and using a cell
phone.
Defensive Driving
Defensive driving means
“always
expect the unexpected.” The first step
in driving defensively is to wear the
safety belt. See Safety Belts067.
. Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
. Allow enough following distance
between you and the driver in
front of you.
. Focus on the task of driving.
Control of a Vehicle
Braking, steering, and accelerating are
important factors in helping to control
a vehicle while driving.

DRIVING AND OPERATING 207
Caution
Driving with the parking brake on
can overheat the brake system and
cause premature wear or damage to
brake system parts. Make sure that
the parking brake is fully released
and the brake warning light is off
before driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive
away. Avoid rapid acceleration when
the EPB is applied, to preserve parking
brake lining life.
Brake Assist
This vehicle has a brake assist feature
designed to assist the driver in
stopping or decreasing vehicle speed
in emergency driving conditions. This
feature uses the stability system
hydraulic brake control module to
supplement the power brake system
under conditions where the driver has
quickly and forcefully applied thebrake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the vehicle
until the ABS activates. Minor brake
pedal pulsation or pedal movement
during this time is normal and the
driver should continue to apply the
brake pedal as the driving situation
dictates. The brake assist feature will
automatically disengage when the
brake pedal is released or brake pedal
pressure is quickly decreased.
Hill Start Assist (HSA)
Hill Start Assist (HSA) may
automatically activate when the
vehicle is stopped on a hill and
Automatic Vehicle Hold (AVH) is not
enabled. This feature is designed to
prevent the vehicle from rolling, either
forward or rearward, during vehicle
drive off. During the transition from
releasing the brake pedal to
accelerating to drive off on a hill, HSA
holds the braking pressure to prevent
rolling. HSA will not activate if the
vehicle is in a drive gear and facing
downhill or if the vehicle is facing
uphill and in R (Reverse).
Automatic Vehicle
Hold (AVH)
Automatic Vehicle Hold (AVH) can be
turned on by pressing AUTO HOLD
with the driver safety belt fastened,
the driver door closed, and the engine
running. The AVH indicator will
come on.
This feature will activate when the
vehicle is stopped to prevent it from
moving. After the brake pedal has
been released and before the

Cadillac CT6 Owner Manual (GMNA-Localizing-MidEast-10293390) - 2017 -
CRC - 6/21/16
208 DRIVING AND OPERATING
accelerator pedal has been pressed,
AVH uses braking pressure to hold the
vehicle stationary. In addition, the
ABS pump motor may activate to
build brake pressure to maintain the
vehicle at a standstill if necessary.
If AVH is holding the vehicle, the AVH
indicator will change to green. Once
AVH is active it will hold the vehicle
for a defined time period then engage
the parking brake. While AVH is
holding the vehicle, the parking brake
will engage if the driver door is
opened or the driver safety belt is
unfastened.Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak®, an
electronic stability control system.
These systems help limit wheel spin
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, TCS applies the brakes to the
spinning wheels and reduces engine
power to limit wheel spin.
StabiliTrak activates when the vehicle
senses a difference between the
intended path and the direction the
vehicle is actually traveling.
StabiliTrak selectively applies braking
pressure to any one of the vehicle
wheel brakes to assist the driver in
keeping the vehicle on the
intended path. If cruise control is being used and
traction control or StabiliTrak 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 0190 and “Turning
the Systems Off and On ”later in this
section.

218 DRIVING AND OPERATING
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected follow gap. The vehicle speed
increases or decreases to follow the
vehicle in front of you, but will not
exceed the set speed. It may apply
limited braking, if necessary. When
braking is active, the brake lights will
come on. The automatic braking may
feel or sound different than if the
brakes were applied manually. This is
normal.
Stationary or Very Slow-Moving
Objects
{Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a vehicle
it has never detected moving. This
can occur in stop-and-go traffic or
when a vehicle suddenly appears
due to a vehicle ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use(Continued)
Warning (Continued)
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes.
ACC Automatically Disengages
ACC may automatically disengage and
you will need to manually apply the
brakes to slow the vehicle when:
. The sensors are blocked.
. The Traction Control System (TCS)
or electronic stability control
system has activated or been
disabled.
. No traffic or other objects are
being detected.
. There is a fault in the system.
The ACC indicator will not be
displayed when ACC is no longer
active. Notification to Resume ACC
ACC will maintain a follow gap behind
a detected vehicle and slow your
vehicle to a stop behind that vehicle.
If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead indicator
will flash as a reminder to check
traffic ahead before proceeding. In
addition, the left and right sides of the
Safety Alert Seat will pulse three
times, or three beeps will sound. See
”Alert Type
”and “Go Notifier” in
“Collision/Detection Systems” under
Vehicle Personalization 0152.
When the vehicle ahead drives away,
ACC resumes automatically if the stop
was brief. If necessary, press RES+ or
the accelerator pedal to resume ACC.
If stopped for more than two minutes
or if the driver door is opened and the
driver safety belt is unbuckled, the
ACC automatically applies the Electric
Parking Brake (EPB) to hold the
vehicle. The Electric Parking Brake
status light will turn on. See Electric
Parking Brake 0205. To resume ACC
and release the EPB, press the
accelerator pedal.
