DRIVING AND OPERATING 201
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.
Parking Brake (Electric)
Automatic Transmission
Manual Transmission
If equipped with an Electric Parking
Brake (EPB), the switch is on the
center console for manual
transmission vehicles, or on the left
side of the instrument panel for
automatic transmission vehicles. The
EPB can always be activated, even if
the ignition is off. To prevent draining
the battery, avoid repeated cycles of
the EPB when the engine is not
running.

204 DRIVING AND OPERATING
Hill Start Assist (HSA)
This vehicle has a Hill Start Assist
(HSA) feature, which may be useful
when the vehicle is stopped on a
grade sufficient enough to activate
HSA. This feature is designed to
prevent the vehicle from rolling, either
forward or rearward, during vehicle
drive off. After the driver completely
stops and holds the vehicle in a
complete standstill on a grade, HSA
will be automatically activated. During
the transition period between when
the driver releases the brake pedal and
starts to accelerate to drive off on a
grade, HSA holds the braking pressure
for a maximum of two seconds to
ensure that there is no rolling. The
brakes will automatically release when
the accelerator pedal is applied within
the two-second window. It 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).
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak/
Electronic Stability Control (ESC).
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/ESC activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak/ESC 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 TCS
or StabiliTrak/ESC 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 0181 and “Turning
the Systems Off and On ”later in this
section.

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12460272) - 2019 - crc - 5/8/18
DRIVING AND OPERATING 205
The indicator light for both systems is
in the instrument cluster. This
light will:
.Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak/ESC 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 may display in the
Driver Information Center (DIC), and
dcomes 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
dcomes 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
dcomes on and stays on, the
vehicle may need more time to
diagnose the problem. If the condition
persists, see your dealer.
Turning the Systems Off and On
Thegbutton for TCS and StabiliTrak/
ESC is on the center console (ATS) or
the steering wheel (ATS-V).
Caution

package, available features, and mode
selected, the suspension, steering, and
powertrain will change settings to
achieve the desired mode
characteristics. If the vehicle is
equipped with Magnetic Ride Control,
selecting the various Driver Modes
adjusts the ride of the vehicle to
enhance the ride performance for the
road conditions and the
selected mode.
The Driver Mode Control has three or
four modes: Tour, Sport, Snow/Ice,
and Track (V-Series Only). Snow/Ice
mode is only available on automatic
transmission vehicles. Press and
release the MODE button (ATS) or
press the
yorzbutton (ATS-V) on
the center console to activate the
mode menu in the cluster. The first
press of the button will show the
current mode. Subsequent presses will
scroll though the available modes. The
Tour and Sport modes will feel similar
on a smooth road. Select a new
setting whenever driving conditions
change.
Tour Mode
Use for normal city and highway
driving to provide a smooth, soft ride.
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 or Track 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 0194. The
steering will change to provide more
precise control. If the vehicle has
Magnetic Ride Control, the suspension
will change to provide better
cornering performance.
Competitive Driving Mode can be
accessed through this mode.
Snow/Ice Mode
Use when more traction is needed
during slippery conditions.
Snow/Ice mode will use a different
accelerator pedal map to optimize
traction on a slippery surface. The
accelerator pedal will reduce engine
torque at small pedal inputs. The
transmission will also shift differently
to assist in maintaining traction.
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 0181.

Launch Control (V-Series Only)
A Launch Control feature is available,
within Competitive Driving Mode
(V-Series) or Performance Traction
Management (V-Series), to allow the
driver to achieve high levels of vehicle
acceleration in a straight line. Launch
Control is a form of traction control
that manages tire spin while
launching the vehicle. This feature is
intended for use during closed course race events where consistent zero to
60 and quarter mile times are
desirable.
Launch Control is only available when
the following criteria are met:
.
Competitive Driving Mode is
selected (V-Series) or any of the
Performance Traction
Management modes are selected
(V-Series). The TCS light comes on
in the instrument cluster and the
appropriate DIC message displays.
. The vehicle is not moving.
. The steering wheel is pointing
straight.
Manual Transmissions
. The clutch is pressed and the
vehicle is in 1 (First) gear.
. The accelerator pedal is rapidly
applied 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 clutch, while

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 213
Cruise Control
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).
{Warning
Cruise 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.If equipped with a manual
transmission and 2.0L L4 engine
(LTG), the cruise control will remain
active when the gears are shifted. The
cruise is deactivated if the clutch is
pressed for several seconds. In an
ATS-V Series vehicle, cruise control is
canceled immediately with the
activation of the clutch pedal.
If the StabiliTrak/Electronic Stability
Control (ESC) system begins to limit
wheel spin while using cruise control,
the cruise control automatically
disengages. See
Traction Control/
Electronic Stability Control 0204. If a
collision alert occurs when cruise
control is activated, cruise control is
disengaged. See Forward Collision Alert
(FCA) System 0228. When road
conditions allow you to safely use it
again, cruise control can be turned
back on.
Turning off the TCS or StabiliTrak/
ESC system will disengage cruise
control.
If the brakes are applied, cruise
control disengages.
J: Press to turn the system on and
off. A white cruise control indicator
appears in the instrument cluster
when cruise is turned on.
+RES : If there is a set speed in
memory, press the control up briefly
to resume that speed or hold to
accelerate. If cruise control is already
active, use to increase vehicle speed.
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.
