174 DRIVING AND OPERATING
Caution
Low oil levels can damage the
engine. If using the vehicle for
competitive driving, the engine may
use more oil than it would with
normal use. Check the oil level
often during competitive driving.
Competitive Driving Mode can be
selected. See Driver Mode Control
0 205.

.
The 3.6L V6 twin turbo engine
(LF4) comes standard with a 7 qt
sump, integrated oil cooler, and
other powertrain and powertrain
cooling components in preparation
for track use.
Fuel
Use premium unleaded gasoline with
a posted octane rating of 93 at a track
event. Unleaded gasoline with a
posted octane rating of 91 may be
used, but performance will be
degraded.
Automatic Transmission Fluid
Have the transmission fluid set to the
track specific oil level prior to track
usage. Transmission fluid should be
changed after every 15 hours of track
usage. Any transmission level set or
change should be performed at your
dealer.
Manual Transmission Fluid
Manual transmission fluid should be
changed after every 15 hours of track
usage.
Brake Fluid
.Before racing, replace existing
brake fluid with a qualified racing
brake fluid from a sealed
container. Brake fluid with a dry
boiling point >279 °C (534 °F) is
qualified. If racing brake fluid is
used, replace it with GM approved
brake fluid before driving on
public roads. See Recommended
Fluids and Lubricants 0337.
. Do not use silicone-based fluids.
If racing brake fluid is in the vehicle
and the age of the brake fluid is over a
month old or unknown, replace the
brake fluid between racing/closed
track driving.

DRIVING AND OPERATING 175
Caution
Failure to change the brake fluid
and transfer case fluid after any
performance or race track driving
could result in damage not covered
by the vehicle warranty. Have the
brake fluid and transfer case fluid
changed by your dealer after any
performance or race track driving.
SeeRecommended Fluids and
Lubricants 0337.
Brake Burnishing
For vehicles equipped with front
Brembo brake systems:
Base Vehicles Only: Performance/
racing brake pads are required prior to
racing or closed track driving. Vehicles
with option code Y4Q have
performance brake pads.
New brake pads must be burnished
before racing or other competitive
driving.
Caution
Performing the brake burnish
procedure on a base brake system
can result in brake damage.
Caution
The new vehicle break-in period
should be completed before
performing the brake burnish
procedure, otherwise damage may
occur to the powertrain/engine. See
New Vehicle Break-In 0184.
Caution
Brake pedal fade will occur during
any track burnish procedure and
can cause brake pedal travel and
force to increase. This could extend
stopping distance until the brakes
are fully burnished. When this procedure is performed as
instructed, it will not damage the
brakes. The brake pads will smoke and
produce an odor. The braking force
and pedal travel may increase. After
the procedure, the brake pads may
appear white at the rotor contact.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor
vehicle operation.
Brake Burnish Procedure (V-Series
and Y4Q Only)
1. Apply the brakes 25 times starting at 100 km/h (60 mph) to
50 km/h (30 mph) while
decelerating at 0.4 g. This is a
medium brake application. Drive
for at least 1 km (0.6 mi)
between applying the brakes.
This first step may be skipped if
there are more than 320 km
(200 mi) on the brake pads.
2. Repeatedly apply the brakes from 100 km/h (60 mph) to 25 km/h
(15 mph) while decelerating at
0.8 g. This is a hard brake

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12460272) - 2019 - crc - 5/8/18
DRIVING AND OPERATING 179
.Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper tread
depth. See Tires0282.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving on
flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the vehicle
on a long downhill slope can cause
brake overheating, can reduce brake
performance, and could result in a
loss of braking. Shift the
(Continued)
Warning (Continued)
transmission to a lower gear to let
the engine assist the brakes on a
steep downhill slope.
{Warning
Coasting downhill in N (Neutral) or
with the ignition off is dangerous.
This can cause overheating of the
brakes and loss of steering assist.
Always have the engine running
and the vehicle in gear.
. Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills; something
could be in your lane (e.g., stalled
car, crash). .
Pay attention to special road signs
(e.g., falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and the
road creates less traction or grip, so
drive carefully. Wet ice can occur at
about 0 °C (32 °F) when freezing rain
begins to fall. Avoid driving on wet ice
or in freezing rain until roads can be
treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick.
. Turn on Traction Control. See
Traction Control/Electronic Stability
Control 0204.
. Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes should

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12460272) - 2019 - crc - 5/8/18
180 DRIVING AND OPERATING
be applied sooner than when on
dry pavement. SeeAntilock Brake
System (ABS) 0200.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas. The
surface of a curve or an overpass
can remain icy when the
surrounding roads are clear. Avoid
sudden steering maneuvers and
braking while on ice.
. Turn off cruise control.
Blizzard Conditions
Stay with the vehicle unless there is
help nearby. If possible, use Roadside
Assistance. See Roadside Service 0350.
To get help and keep everyone in the
vehicle safe:
. Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may cause
exhaust gases to get inside. Engine
exhaust contains carbon monoxide
(CO), which cannot be seen or
smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in snow:
. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side that
is away from the wind, to
bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
. Adjust the climate control
system to circulate the air
inside the vehicle and set the
(Continued)
Warning (Continued)
fan speed to the highest
setting. See“Climate Control
Systems.”
For more information about CO, see
Engine Exhaust 0193.
To save fuel, run the engine for short
periods to warm the vehicle and then
shut the engine off and partially close
the window. Moving about to keep
warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle speed.
This keeps the battery charged to
restart the vehicle and to signal for
help with the headlamps. Do this as
little as possible, to save fuel.

12460272) - 2019 - crc - 5/8/18
DRIVING AND OPERATING 181
If the Vehicle Is Stuck
Slowly and cautiously spin the wheels
to free the vehicle when stuck in sand,
mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. SeeTraction Control/
Electronic Stability Control 0204.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you or
others could be injured. The vehicle
can overheat, causing an engine
compartment fire or other damage.
Spin the wheels as little as possible
and avoid going above 56 km/h
(35 mph).
Rocking the Vehicle to Get it Out
Turn the steering wheel left and right
to clear the area around the front
wheels. Turn off any traction system.
Shift back and forth between
R (Reverse) and a low forward gear, spinning the wheels as little as
possible. To prevent transmission
wear, wait until the wheels stop
spinning before shifting gears. Release
the accelerator pedal while shifting,
and press lightly on the accelerator
pedal when the transmission is in
gear. Slowly spinning the wheels in
the forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out, see
Towing the Vehicle
0314.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can carry.
This weight is called the vehicle
capacity weight and includes the
weight of all occupants, cargo, and
all nonfactory-installed options.
Two labels on the vehicle may
show how much weight it may
properly carry: the Tire and
Loading Information label and the
Certification label.
{Warning
Do not load the vehicle any
heavier than the Gross Vehicle
Weight Rating (GVWR),
or either the maximum front or
rear Gross Axle Weight Rating
(GAWR). This can cause
systems to break and change
the way the vehicle handles.
This could cause loss of control
and a crash. Overloading can
also reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12460272) - 2019 - crc - 5/8/18
184 DRIVING AND OPERATING
weight of the driver, passengers,
and cargo should never exceed the
vehicle's capacity weight.
Certification Label
Label Example
A vehicle-specific Certification
label is attached to the vehicle's
center pillar (B-pillar). The label
may show the gross weight
capacity of the vehicle, called the
Gross Vehicle Weight Rating
(GVWR). The GVWR includes the
weight of the vehicle, all
occupants, fuel, and cargo.
{Warning
Things inside the vehicle can
strike and injure people in a
sudden stop or turn, or in a
crash.
.Put things in the cargo
area of the vehicle. In the
cargo area, put them as far
forward as possible. Try to
spread the weight evenly.
.Never stack heavier things,
like suitcases, inside the
vehicle so that some of
them are above the tops of
the seats.
.Do not leave an unsecured
child restraint in the
vehicle.
.Secure loose items in the
vehicle.
.Do not leave a seat folded
down unless needed.
Starting and Operating
New Vehicle Break-In
Follow these recommended guidelines
during the first 2 414 km (1,500 mi) of
driving this vehicle. Parts have a
break-in period and performance will
be better in the long run.
For the first 2 414 km (1,500 mi):
. Avoid full throttle starts and
abrupt stops.
. Do not exceed 4000 engine rpm.
. Avoid driving at any one constant
speed, fast or slow.
. Avoid downshifting to brake or
slow the vehicle when the engine
speed will exceed 4000 rpm.
. Do not let the engine labor. Never
lug the engine in high gear at low
speeds. With a manual
transmission, shift to the next
lower gear. This rule applies at all
times, not just during the break-in
period.

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12460272) - 2019 - crc - 5/8/18
DRIVING AND OPERATING 185
.Check engine oil with every
refueling and add if necessary. Oil
and fuel consumption may be
higher than normal during the
first 2 414 km (1,500 mi).
. New brake linings also need a
break-in period. Avoid making
hard stops during the first
322 km (200 mi). This is
recommended every time brake
linings are replaced.
Composite Materials
This vehicle may be equipped with
parts containing carbon fiber,
sheet-molding compound, or other
composite materials. Dealer-installed
accessories may also contain
composite materials. These parts and
accessories may include the splitter or
rocker extensions.
{Warning
Exposed edges of parts containing
carbon fiber and other composite
materials can be sharp. Contact
with these parts could result in
injury. Use caution to avoid
contacting these parts, including
when washing the vehicle. If the
parts are damaged, replace the
parts promptly with replacements
from your dealer.
{Warning
Rocker extensions may break under
pressure, resulting in property
damage or injury. Do not stand on
the rocker extension or use it as
a step.
Ignition Positions
The vehicle has an electronic keyless
ignition with pushbutton start.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interference to
the Keyless Access system. See Remote
Keyless Entry (RKE) System Operation
0 29.
To shift out of P (Park), the vehicle
must be in on and the brake pedal
must be applied.

186 DRIVING AND OPERATING
Stopping the Engine/OFF (No
Indicator Lights) :When the vehicle
is stopped, press ENGINE START/
STOP once to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0190.
Automatic Transmission
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).
When the vehicle is shifted into
P (Park), the ignition will turn off.
Manual Transmission
If the vehicle is stationary, the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0190.
The vehicle may have an electric
steering column lock. The lock is
activated when the ignition is turned
off and either front door is opened.
A sound may be heard as the lock actuates or releases. The steering
column lock may not release with the
wheels turned off center. If this
happens, the vehicle may not start.
Move the steering wheel from left to
right while attempting to start the
vehicle. If this does not work, the
vehicle needs service.
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) with an automatic
transmission, or Neutral with a
manual transmission. Turn the
ignition off.
4. Set the parking brake. See Parking Brake (Electric) 0201
or Parking Brake (Manual) 0203.
{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 ENGINE START/STOP
for longer than two seconds, or press
twice within five seconds.
