22 IN BRIEF
Rear Cross Traffic Alert
(RCTA) System
If equipped, the RCTA system shows a
triangle with an arrow on the
infotainment display to warn of traffic
behind your vehicle that may cross
your vehicle's path while in
R (Reverse). In addition, beeps will
sound, or the driver seat will pulse.
SeeAssistance Systems for Parking or
Backing 0224.
Park Assist
If equipped, Rear Park Assist (RPA)
uses sensors on the rear bumper to
assist with parking and avoiding
objects while in R (Reverse).
It operates at speeds less than 8 km/h
(5 mph). RPA may show a warning
triangle on the infotainment display
and a graphic on the instrument
cluster to provide the object distance.
In addition, multiple beeps or seat
pulses may occur if very close to an
object.
The vehicle may also have the Front
Park Assist system. See
Assistance Systems for Parking or
Backing 0224.
Reverse Automatic
Braking (RAB)
If the vehicle has Adaptive Cruise
Control (ACC) it also has the RAB
system, which is designed to help
avoid or reduce the harm caused by
backing crashes when the vehicle is
shifted into R (Reverse). If the system
detects the vehicle is backing too fast
to avoid a crash with a detected object
behind your vehicle in your path, it
may automatically brake hard to
a stop.
See Assistance Systems for Parking or
Backing 0224.
Power Outlets
The accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone or MP3 player. The vehicle has two accessory power
outlets:
.
Inside the instrument panel
storage area below the climate
control system.
. On the rear of the center floor
console.
Lift the cover to access the accessory
power outlet.
See Power Outlets 0108.

LIGHTING 147
.The light sensor determines it is
daytime.
. The parking brake is released or
the vehicle is not in P (Park).
The taillamps, sidemarker lamps,
instrument panel lights, and other
lamps will not be on.
The DRL turn off when the headlamps
are turned to
Oor the ignition is off.
For vehicles first sold in Canada, the
DRL can only be turned off when the
transmission is in P (Park).
Automatic Headlamp
System
When the exterior lamp control is set
to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor, otherwise the headlamps will
come on when they are not needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it is
light outside when the vehicle leaves
the garage, there is a slight delay
before the automatic headlamp
system changes to the DRL. During
that delay, the instrument cluster may
not be as bright as usual. Make sure
the instrument panel brightness control is in the full bright position.
See
Instrument Panel Illumination
Control 0149.
When it is bright enough outside, the
headlamps will turn off or may change
to Daytime Running Lamps (DRL).
The automatic headlamp system turns
off when the exterior lamp control is
turned to
Oor the ignition is off.
Lights On with Wipers
If the windshield wipers are activated
in daylight with the engine on, and
the exterior lamp control is in AUTO,
the headlamps, parking lamps, and
other exterior lamps come on. The
transition time for the lamps coming
on varies based on wiper speed. When
the wipers are not operating, these
lamps turn off. Move the exterior
lamp control to
Oor;to disable
this feature.

maintaining the fully pressed
accelerator pedal, will manage wheel
slip. Complete shifts as described in
Manual Transmission0198.
Automatic Transmissions
. The brake pedal must be firmly
pressed to the floor, equivalent to
a panic brake event.
. The accelerator pedal is rapidly
applied to wide open throttle. (If
the vehicle rolls due to wide open
throttle, release the throttle, press
the brake pedal more firmly, and
re-apply the accelerator to wide
open throttle.)
The Launch Control feature will
initially limit engine speed as the
driver rapidly applies the accelerator
pedal to wide open throttle. Allow the
engine rpm to stabilize. A smooth,
quick release of the brake pedal, while
maintaining the fully pressed
accelerator pedal, will manage
wheel slip.
After the vehicle is launched, the
system continues in Performance
Traction Management (V-Series). Competitive Driving Mode, PTM, and
Launch Control are systems designed
for a closed course race track and not
intended for use on public roads. The
systems are not intended to
compensate for lack of driver
experience or familiarity with the race
track.
Limited-Slip Rear Axle
(Except V-Series)
If equipped, the mechanical
limited-slip differential can give more
traction on snow, mud, ice, sand,
or gravel. It works like a standard axle
most of the time, but when traction is
low, this feature allows the drive
wheel with the most traction to move
the vehicle. For vehicles with
limited-slip differential, driven under
severe conditions, the rear axle fluid
should be changed.
See
Competitive Driving Mode (FE3
Only) 0209 and Maintenance Schedule
0 327.
Limited-Slip Rear Axle
(V-Series Only)
If equipped, the Electronic
Limited-Slip Differential (eLSD) is
automatically activated. eLSD actively
monitors vehicle sensors and driver
inputs to determine the amount of
change for the conditions. With eLSD,
the vehicle has:
.
Enhanced high-speed control.
. Improved traction through
corners, allowing more
acceleration.
. More precise steering.
. Increased vehicle agility.
. Integration with StabiliTrak/
Electronic Stability Control (ESC).
For vehicles with eLSD, driven under
severe conditions, the rear axle fluid
should be changed.
See Competitive Driving Mode (FE3
Only) 0209 and Maintenance Schedule
0 327.

DRIVING AND OPERATING 215
For each press, the vehicle speed
decreases to the next 5 km/h
(5 mph) mark on the speedometer.
The cruise control system may
automatically brake to slow the
vehicle down (ATS model only).
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster 0113.
The increment value used depends on
the units displayed.
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– control will result
in cruise control set to the current
vehicle speed.
Using Cruise Control on Hills
How well 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 (ATS
only), and the transmission may
downshift to a lower gear, to slow the
vehicle down. 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 will
disengage.
Ending Cruise Control
There are five ways to end cruise
control:
.
Step lightly on the brake pedal
(manual and automatic
transmissions).
. Press the clutch pedal for several
seconds or shift to Neutral
(manual transmissions).
. Shift the transmission to
N (Neutral).
. Press
*.
. 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 for selecting
the cruise control set speed and
following gap. Read this entire section
before using this system. ACC uses a
camera and radar sensors to detect
other vehicles. See Radio Frequency
Statement 0356. The following gap is
the following time (or distance)
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.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
limited, moderate braking to maintain
the selected following gap. To
disengage ACC, apply the brake. If the
Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates while ACC is

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12460272) - 2019 - crc - 5/8/18
216 DRIVING AND OPERATING
engaged, ACC may automatically
disengage. SeeTraction Control/
Electronic Stability Control 0204. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC
will not engage if the TCS or
StabiliTrak/ESC 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
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0171.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
. On winding and hilly roads or
when the sensors are blocked
by snow, ice, or dirt. The
system may not detect a
vehicle ahead. Keep the entire
front of the vehicle clean.
. Visibility is low, such as in
fog, rain, or snow conditions.
ACC performance is limited
under these conditions.
. On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
J:Press to turn the system on or
off. The indicator turns white on the
instrument cluster when ACC is
turned on.
+RES : Press the control up briefly to
resume the previous set speed or to
increase vehicle speed if ACC is
already engaged. To increase speed by
1 km/h (1 mph), press +RES up to the
first detent. To increase speed to the
next 5 km/h (5 mph) mark on the
speedometer, press +RES up to the
second detent.
SET– :Press the control down briefly
to set the speed and activate ACC or
to decrease vehicle speed if ACC is

220 DRIVING AND OPERATING
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 lamps 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
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
the driver will need to manually apply
the brakes to slow the vehicle if:
.
The sensors are blocked.
. The Traction Control System (TCS)
or StabiliTrak/ESC system has
activated or been disabled.
. There is a fault in the system.
. The radar falsely reports a
blockage when driving in a desert
or remote area with no other
vehicles or roadside objects. A DIC
message may display to indicate
that ACC is temporarily
unavailable.
The ACC active symbol will turn white
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 before proceeding. In addition,
the left and right sides of the Safety
Alert Seat will pulse three times,
or three beeps will sound. See
“Switching Between ACC and Regular
Cruise Control
”previously in this
section. See “Alert Type”and
“Adaptive Cruise Go Notifier” in
“Collision/Detection Systems” under
Vehicle Personalization 0135.
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 seat belt is
unbuckled, the ACC automatically
applies the Electric Parking Brake
(EPB) to hold the vehicle. The EPB
status light will turn on.
See Parking Brake (Electric) 0201 or
Parking Brake (Manual) 0203. To
resume ACC and release the EPB,
press the accelerator pedal. ACC can
be resumed when the vehicle is
traveling greater than 5 km/h (3 mph).
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0134.

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 Park 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 Park Assist,
always check the area around the
vehicle and check all mirrors before
moving forward or backing.
The instrument cluster may have a
Park Assist display with bars that
show“distance to object ”and object
location information for the Park
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 on
object location, 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 a
potential object threat 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.

DRIVING AND OPERATING 229
FCA can be disabled with either the
FCA steering wheel control or,
if equipped, through vehicle
personalization. See“Collision/
Detection Systems” underVehicle
Personalization 0135.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected, the
vehicle ahead indicator will display
green. Vehicles may not be detected
on curves, highway exit ramps,
or hills, due to poor visibility; or if a
vehicle ahead is partially blocked by
pedestrians or other objects. FCA will
not detect another vehicle ahead until
it is completely in the driving lane.
{Warning
FCA does not provide a warning to
help avoid a crash, unless it detects
a vehicle. FCA may not detect a
vehicle ahead if the FCA sensor is
blocked by dirt, snow, or ice, or if
the windshield is damaged. It may
also not detect a vehicle on winding
or hilly roads, or in conditions that
can limit visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
Collision Alert
With Head-Up Display
Without Head-Up Display
When your vehicle approaches
another detected vehicle too rapidly,
the red FCA display will flash on the
windshield. Also, eight high-pitched
beeps will sound from the front,
or both sides of the Safety Alert Seat
will pulse five times. When this
Collision Alert occurs, the brake
system may prepare for driver braking
to occur more rapidly which can cause
a brief, mild deceleration. Continue to
apply the brake pedal as needed.
Cruise control may be disengaged
when the Collision Alert occurs.
