If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display a message in
the Driver Information Center (DIC).
See Transmission Messages 0147.
When the vehicle is shifted into
P (Park), the ignition system will
switch to OFF.
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), and turn the ignition to
OFF. On vehicles with an
automatic transmission, the shift
lever must be in P (Park) to turn
the ignition switch to the OFF
position.
4. Set the parking brake. See Electric Parking Brake 0207.{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 the ENGINE START/
STOP button for longer than
two seconds, or press twice in
five seconds.
ACC/ACCESSORY (Amber Indicator
Light) : This mode allows you to use
some electrical accessories when the
engine is off.

battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after five to 10 seconds, especially in
very cold weather (below −18 °C
or 0 °F), it could be flooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the floor and holding it there
as you press ENGINE START/
STOP, if equipped. Wait at least
15 seconds between each try, to
allow the cranking motor to cool
down. When the engine starts,
release the accelerator. If the
vehicle starts briefly but then
stops again, do the same thing.
This clears the extra gasoline
from the engine. Do not race the
engine immediately after starting
it. Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Stop/Start System
{Warning
Exiting the vehicle without first
shifting into P (Park) may cause the
vehicle to move. You or others may
be injured. Because the vehicle has
the auto engine stop/start feature,
the vehicle's engine might seem to
be shut off; however, once the brake
pedal is released, the engine will
start up again.
Shift to P (Park) and turn the
ignition to LOCK/OFF, before exiting
the vehicle.
If equipped with the 2.0L L4, or 3.6L
V6 non-turbo engine, the vehicle has a
fuel saving stop/start system to shut
off the engine to help conserve fuel.
Auto Engine Stop/Start
When the brakes are applied and the
vehicle is at a complete stop, the
engine may turn off. When stopped,
the tachometer may display Auto
Stop, or the Auto Stop light may come
on in the instrument cluster. See
Tachometer 0118 and Auto Stop
Mode (Uplevel Cluster Only) 0130.
When the brake pedal is released or
the accelerator pedal is pressed, the
engine may restart.
Auto Stop may be deactivated if:
. A minimum vehicle speed is not
reached.
. The engine or transmission is not
at the required operating
temperature.
. The outside temperature is not in
the required operating range.
Typically below −10 °C (14 °F) or
above 50 °C (122 °F).
. The shift lever is in any gear other
than D (Drive).
. The battery has been recently
disconnected.
. The battery charge is low.
. The interior comfort level has not
reached the required level for the
climate control system or defog
settings. See Dual Automatic
Climate Control System 0172.
. The Auto Stop time is greater than
two minutes.

climbing or descending hills, to stay in
gear longer, or to downshift for more
power or engine braking.
The transmission will only allow you
to shift into gears appropriate for the
vehicle speed and engine revolutions
per minute (rpm). The transmission
will not automatically shift to the next
lower gear if the engine rpm is too
high, nor to the next higher gear when
the maximum engine rpm is reached.
If shifting is prevented for any reason,
a SHIFT DENIED message will be
displayed in the instrument cluster.
SeeTransmission Messages 0147.
When accelerating the vehicle from a
stop in snowy and icy conditions, it is
suggested to shift into second gear.
A higher gear allows the vehicle to
gain more traction on slippery
surfaces.Drive Systems
All-Wheel Drive
Vehicles with this feature always send
engine power to all four wheels. It is
fully automatic, and adjusts itself as
needed for road conditions.
Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock Brake
System (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 may be heard
while this test is going on, and it may
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 0126.
If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to avoid

DRIVING AND OPERATING 207
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
The vehicle has an Electric Parking
Brake (EPB). The switch for the EPB is
on the instrument panel, to the left of
the steering wheel. 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. SeeParking Brake
Light 0125 and Service Electric Parking
Brake Light 0126. There are also
parking brake-related Driver
Information Center (DIC) messages.
See Brake System Messages 0138. 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.

Cadillac CTS/CTS-V Owner Manual (GMNA-Localizing-MidEast-10293089) -
2017 - crc - 6/22/16
208 DRIVING AND OPERATING
2. Lift up the EPB switchmomentarily.
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 Parking Brake Light 0125.
If the amber parking brake warning
light is on, lift up on the EPB switch
and hold it up. 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 held up. If the
switch is held up 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, the rear
wheels should be blocked to prevent
vehicle movement.
EPB Release
To release the EPB:
1. Place the ignition in the ACC/ ACCESSORY or ON/RUN
position.
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 brake status light
is off. If either light stays on after
release is attempted, see your dealer.
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 the

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 previously set cruise
speed. While pressing the accelerator
pedal or shortly following the release
to override cruise control, briefly
applying the SET–switch will result in
cruise control 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 the vehicle speed.
When going downhill, the cruise
control system may automatically
brake to slow the vehicle down (CTS
model only). Also, you may have to
brake or shift to a lower gear to keep
the vehicle speed down. If the brake
pedal is applied, cruise control
disengages. Ending Cruise Control
There are four ways to end cruise
control:
.
Step lightly on the brake pedal.
. Press
*.
. Shift the transmission to
N (Neutral).
. Press
J.
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
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed and
following gap. 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. If a vehicle is detected in your path,
ACC can apply acceleration or limited,
moderate braking to maintain the
selected following gap. To disengage
ACC, apply the brake. If ACC is
controlling your vehicle speed when
the Traction Control System (TCS) or
electronic stability control system
activates, the ACC may automatically
disengage. See
Traction Control/
Electronic Stability Control 0209. When
road conditions allow ACC to be safely
used, the ACC can be turned back on.
ACC will not engage if the TCS or
electronic stability control system is
disabled.{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver” in this section.
Complete attention is always

DRIVING AND OPERATING 225
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 symbol
will flash as a reminder to check
traffic 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” underVehicle
Personalization 0149.
When the vehicle ahead drives away,
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 to
hold the vehicle. The electric parking
brake status light will turn on. See
Electric Parking Brake 0207. To release
the electric parking brake, press the
accelerator pedal. A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See
Vehicle
Messages 0138.
{Warning
If ACC has stopped the vehicle, and
if ACC is disengaged, turned off,
or canceled, the vehicle will no
longer be held at a stop. The vehicle
can move. When ACC is holding the
vehicle at a stop, always be
prepared to manually apply the
brakes.
{Warning
Leaving the vehicle without placing
it in P (Park) can be dangerous. Do
not leave the vehicle while it is
being held at a stop by ACC. Always
place the vehicle in P (Park) and
turn off the ignition before leaving
the vehicle. ACC Override
If using the accelerator pedal while
ACC is active, a warning message on
the DIC and in the HUD (if equipped)
will indicate that automatic braking
will not occur. See
Vehicle Messages
0 138. ACC will resume operation
when the accelerator pedal is not
being pressed.
{Warning
The ACC will not automatically
apply the brakes if your foot is
resting on the accelerator pedal.
You could crash into a vehicle
ahead of you.
Curves in the Road
{Warning
On curves, ACC may not detect a
vehicle ahead in your lane. You
could be startled if the vehicle
accelerates up to the set speed,
especially when following a vehicle (Continued)

DRIVING AND OPERATING 227
Do Not Use ACC on Hills and When
Towing a Trailer
Do not use ACC when driving on steep
hills or when towing a trailer. ACC will
not detect a vehicle in the lane while
driving on steep hills. The driver will
often need to take over acceleration
and braking on steep hills, especially
when towing a trailer. If the brakes are
applied, the ACC disengages.
Ending ACC
There are three ways to
disengage ACC:
.Step lightly on the brake pedal.
. Press

J. Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if
the ignition is turned off.
Cleaning the Sensing System
The camera sensor on the windshield
behind the rearview mirror and the
radar sensors on the front of the
vehicle can become blocked by snow,
ice, dirt, or mud. These areas need to
be cleaned for ACC to operate
properly.
For cleaning instructions, see
“Washing the Vehicle ”under Exterior
Care 0315.
System operation may also be limited
under snow, heavy rain, or road spray
conditions.
Driver Assistance
Systems
This vehicle may have features that
work together to help avoid crashes or
reduce crash damage while driving,
backing, and parking. Read this entire
section before using these systems.
{Warning
Do not rely on the Driver
Assistance Systems. These systems
do not replace the need for paying
attention and driving safely. You
may not hear or feel alerts or
warnings provided by these
systems. Failure to use proper care
when driving may result in injury,
death, or vehicle damage. See

sensors will not detect objects and
can also cause false detections. Keep
the sensors clean of mud, dirt, snow,
ice, and slush; and clean sensors after
a car wash in freezing temperatures.
{Warning
The Parking Assist system does not
detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or that
are too close or too far from the
vehicle. It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle
damage, even with Parking Assist,
always check the area around the
vehicle and check all mirrors before
moving forward or backing.
The instrument cluster may have a
parking assist display with bars that
show“distance to object ”and object
location information for the Parking
Assist system. As the object gets
closer, more bars light up and the bars
change color from yellow to amber
to red.
When an object is first detected in the
rear, one beep will be heard from the
rear, or both sides of the Safety Alert
Seat will pulse two times. When an
object is very close (<0.6 m (2 ft) in the
vehicle rear, or <0.3 m (1 ft) in the
vehicle front), five beeps will sound
from the front or rear depending
where the object is detected, or both
sides of the Safety Alert Seat will
pulse five times. Beeps for FPA are
higher pitched than for RPA. Backing Warning and Reverse
Automatic Braking
Vehicles with Adaptive Cruise Control
(ACC) have the Backing Warning and
Reverse Automatic Braking (RAB)
system. The Backing Warning part of
this system can warn of rear objects
when backing up at speeds greater
than 8 km/h (5 mph).
The Backing Warning System will
beep once from the rear when an
object is first detected, or pulse twice
on both sides of the Safety Alert Seat.
When the system detects a potential
crash, beeps will be heard from the
rear, or five pulses will be felt on both
sides of the Safety Alert Seat. There
may also be a brief, sharp application
of the brakes.
{Warning
The Backing Warning System only
operates at speeds greater than
8 km/h (5 mph). It does not detect
children, pedestrians, bicyclists,
animals, or objects below the
bumper or that are too close or too

Automatic Parking Assist (APA)
If equipped, APA searches for and
steers the vehicle into parallel and
perpendicular parking spots. When
using APA, you must still shift gears,
and control the brakes and
accelerator. A display and audible
beeps help to guide parking
maneuvers.
{Warning
APA does not apply the brakes. APA
may not detect objects in the
parking space, objects that are soft
or narrow, objects high off the
ground such as flatbed trucks,
or objects below ground level such
as large potholes. Always verify that
the parking space is appropriate for
