214 Driving and Operating
Brakes Antilock Brake
System (ABS) This vehicle has ABS, an advanced
electronic braking system that helps
prevent a braking skid.
When the vehicle begins to drive
away, ABS checks itself.
A momentary motor or clicking noise
might be heard while this test is
going on, and it might even be
noticed that the brake pedal moves
a little. This is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning
Light 0 135 .
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to avoid a sudden obstacle, a
computer senses the wheels are
slowing down. If one of the wheels
is about to stop rolling, the computer
will separately work the brakes at
each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS. Using ABS Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You may hear the ABS
pump or motor operating and feel
the brake pedal pulsate. This is
normal.
Braking in Emergencies ABS allows you to steer and brake
at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Electric Parking Brake

Cadillac CT6 Owner Manual (GMNA-Localizing-U.S./Canada-9235592) -
2016 - crc - 11/6/15
Driving and Operating 215The vehicle has an Electric Parking
Brake (EPB). The EPB can always
be activated, even if the ignition is
off. To prevent draining the battery,
avoid repeated cycles of the EPB
system when the engine is not
running.
The system has a red parking brake
status light and an amber parking
brake warning light. See Electric
Parking Brake Light 0 134
and Service Electric Parking Brake
Light 0 134 . There are also parking
brake-related Driver Information
Center (DIC) messages. See Brake
System Messages 0 147 . In case of
insufficient electrical power, the EPB
cannot be applied or released.
Before leaving the vehicle, check
the red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a
complete stop.
2. Press the EPB switch
momentarily. The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes
continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the
light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the red
parking brake status light is flashing.
See your dealer. See Electric
Parking Brake Light 0 134 .
If the amber parking brake warning
light is on, press the EPB switch
and hold it. Continue to hold the
switch until the red parking brake
status light remains on. If the amber
parking brake warning light remains
on, see your dealer.
If the EPB is applied while the
vehicle is moving, the vehicle will
decelerate as long as the switch is
pressed. If the switch is pressed
until the vehicle comes to a stop,
the EPB will remain applied. The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, block the
rear wheels to prevent vehicle
movement.
EPB Release To release the EPB:
1. Place the ignition in the ACC/
ACCESSORY or ON/
RUN mode.
2. Apply and hold the brake
pedal.
3. Push down momentarily on the
EPB switch.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pushing down on the EPB switch
and holding it down. Continue to
hold the switch until the red parking

Automatic Vehicle
Hold (AVH)
AVH can be turned on by pressing
AVH 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
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

218 Driving and Operating 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 0 198
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 is
activated.
.
Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC),
and
d comes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
d comes on and stays on:
1. Stop the vehicle. 2. Turn the engine off and wait
15 seconds.
3. Start the engine.
4. Drive the vehicle.
If
d comes on and stays on, the
vehicle may need more time to
diagnose the problem. If the
condition persists, see your dealer.

220 Driving and Operating If the vehicle is equipped with AWD,
the Tour mode is in between the
Sport and the Snow/Ice modes for a
more balanced feel.
Sport Mode Use where road conditions or
personal preference demand a more
controlled response.
When selected, the Sport mode
indicator will display in the Driver
Information Center (DIC).
When in Sport mode, the vehicle will
shift automatically but may hold a
lower gear longer than it would in
the normal driving mode based on
braking, throttle input, and vehicle
lateral acceleration. See Automatic
Transmission 0 210 . The steering,
including Active Rear Steer (if
equipped), will change to provide
more precise control.
If the vehicle is equipped with AWD,
the Sport mode sends more torque
to the rear wheels. Snow/Ice Mode Use when more traction is needed
during slippery conditions. Snow/Ice
mode will use a different accelerator
pedal map in order to optimize
traction on slippery surfaces.
When selected, the Snow/Ice mode
indicator will display in the DIC.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow, or gravel. If the
vehicle becomes stuck, see If the
Vehicle Is Stuck 0 198 .
If the vehicle is equipped with AWD,
the Snow/Ice mode will provide
more torque to the front wheels. Cruise Control
{ WarningCruise 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 the Traction Control/electronic
stability control system begins to
limit wheel spin while using cruise
control, the cruise control

units. See Instrument Cluster
(Uplevel) 0 121 or Instrument
Cluster (Base Level) 0 118 . The
increment value used depends on
the units displayed.
Selecting the Follow Distance Gap
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected.
Press
[ on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap
setting displays briefly on the
instrument cluster and HUD. The
gap setting will be maintained until it
is changed.
Since each gap setting corresponds
to a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further back your vehicle will follow a
vehicle detected ahead. Consider
traffic and weather conditions when
selecting the following gap. The
range of selectable gaps may not be
appropriate for all drivers and
driving conditions.
Changing the gap setting
automatically changes the alert
timing sensitivity (Far, Medium,
or Near) for the Forward Collision
Alert (FCA) feature. See Forward
Collision Alert (FCA) System 0 237 .
Alerting the Driver
If ACC is engaged, driver action
may be required when ACC cannot
apply sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, the
collision alert symbol on the HUD
will flash on the windshield. Either

once a large enough space is found.
Follow the instructions in the DIC.
When instructed to drive in reverse,
shift to R (Reverse) to engage
automatic steering. The steering
wheel will vibrate briefly as a
reminder to remove hands from the
steering wheel. Check surroundings
and continue braking or accelerating
as needed, and be prepared to stop
to avoid vehicles, pedestrians,
or objects. If the vehicle exceeds
10 km/h (6 mph), APA is
automatically disengaged. A DIC
progress arrow displays the status
of the parking maneuver. Depending
on the space size, additional
maneuvers may be required, and
there will be additional instructions.
When changing gears, allow the
automatic steering to complete
before continuing the parking
maneuver. APA will beep and
display a PARKING COMPLETE
message. Place the vehicle in
P (Park).
APA may automatically disengage if:
.
The steering wheel is used by
the driver. .
The maximum allowed speed is
exceeded.
.
There is a failure with the APA

Assistance Systems for
Driving If equipped, when driving the
vehicle in a forward gear, Forward
Collision Alert (FCA), Lane
Departure Warning (LDW), Lane
Keep Assist (LKA), Side Blind Zone
Alert (SBZA), Lane Change Alert
(LCA), the Front Automatic Braking
(FAB) system, the Front Pedestrian
Braking (FPB) system and/or the Night Vision system can help to
avoid a crash or reduce crash
damage.
Forward Collision Alert
(FCA) System If equipped, the FCA system may
help to avoid or reduce the harm
caused by front-end crashes. When
approaching a vehicle ahead too
quickly, FCA provides a red flashing
alert on the windshield and rapidly
beeps or pulses the driver seat.
FCA also lights an amber visual
alert if following another vehicle
much too closely.
FCA detects vehicles within a
distance of approximately 60 m
(197 ft) and operates at speeds
above 8 km/h (5 mph). If the vehicle
has Adaptive Cruise Control (ACC),
it can detect vehicles to distances of
approximately 110 m (360 ft) and
operates at all speeds. See
Adaptive Cruise Control 0 223 .
