longer than 25 brake
applications.
3. Cool down: Drive at 100 km/h (60 mph) for approximately
15 km (10 mi) without using the
brakes.
4. Apply the brakes 25 times from 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
applications.
Axle Fluid
Axles must have 885 km (500 mi)
before being used in track driving.
The axle fluid temperatures may be
higher than when driving in severe
conditions. Drain and refill with new
fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. See Recommended
Fluids and Lubricants 0314.Caution
During a first time track or racing
event, high axle temperatures can
occur. Damage could be caused to
the axle and would not be covered
by the vehicle warranty. Do not
drive as long or as fast the first
time the vehicle is driven on the
track or raced.
. The axle lubricant should be
replaced with new lubricant.
. Additional cooling capacity is also
required for continuous
competitive driving.
Track Battery
If equipped, this is a lightweight, low
power battery for track use only.
Remove after each event.
Only use this battery when
temperatures are above freezing.
Store in a cool, dry location. Charge
periodically to keep the state of charge
from getting too low. A battery tender
can be used. When installing or removing the track
battery, steps must be followed to
calibrate the electronic throttle
control. See
Battery0255.
Wheel Alignment (V-Series Only)
Wheel alignment suggested specs for
track use:
. Front: -2.0 deg camber, 0.2 deg
total toe
. Rear: -1.7 deg camber, 0.2 deg
total toe
V-Series Vehicles Equipped with
the Original Equipment Tires
Follow the requirements and
recommendations for tire inflation
pressures while driving on various
types of tracks/courses. This helps to
achieve a well-balanced vehicle and
enhance tire traction performance.
Use good judgment to determine the
appropriate tire inflation pressure and
speeds for the track/course
configuration and environmental
conditions. Contact the tire
manufacturer if further assistance is
needed.

DRIVING AND OPERATING 177
To maximize tire life, drive 800 km
(500 mi) prior to racetrack driving or
complete the minimum track running
that will increase the tire pressures by
35 kPa (5 psi). After this, immediately
let the tires cool to cold pressures.
Tire Inflation Pressure
Guidelines
Tire inflation pressures affect vehicle
handling and tire life, and should be
adjusted for various types of tracks/
courses.
Inspect the tires prior to every track/
course session. Track/course driving
will reduce the tire tread life.
Driving and Operating
{Warning
Operating the vehicle at high speeds
can be dangerous. Improper tire
inflation pressure can put
additional strain on the tires and
can cause a sudden failure. Make
sure the tires are in excellent(Continued)
Warning (Continued)
condition, and use the correct cold
tire inflation pressure for the
vehicle load and track/course.
{Warning
Tracks/courses put high loads on
tires operating at high speed, which
can lead to tire failure if not
inflated properly. Always limit
vehicle cargo to the driver plus one
passenger with no additional cargo.
{Warning
Track/course loads wear tires both
on the tread and internal to the
tire. When driven in track/course
conditions, even if tread is not worn
down to the treadwear indicator,
tires must be replaced after the
equivalent of two tanks of fuel or
approximately 160 km (100 mi). Tire Inflation Pressure for Tracks
with Sustained High-Speed
Operation on Banked Turns
(e.g., Daytona International Speedway,
Indianapolis Motor Speedway,
or similar)
Inflate tires to a minimum of 300 kPa
(44 psi) when cold.
Do not reduce tire inflation pressure
when hot.
Tire Inflation Pressure for Tracks
with Combined High-Speed and
High-Load Corners
(e.g., Nurburgring Nordschliefe, Spa
Francorchamps, or similar)
Inflate tires to a minimum of 260 kPa
(38 psi) when cold.
Limit vehicle speed to below 230 km/h
(143 mph) until 290 kPa (42 psi) is
reached.
For continuous track use, hot tire
inflation pressure may be adjusted to
a minimum of 290 kPa (42 psi).

2017 - crc - 6/16/16
178 DRIVING AND OPERATING
Tire Inflation Pressure for Road/
Street Courses
(e.g., Virginia International Raceway,
Road Atlanta, or similar)
Inflate tires to a minimum of 240 kPa
(35 psi) cold.
For continuous road/street course use,
hot tire inflation pressure may be
adjusted to a minimum of 270 kPa
(39 psi).
Return the tires to the recommended
cold tire inflation pressure when
high-speed driving has ended. See
Vehicle Load Limits0181 and Tire
Pressure 0273.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop
and accelerate. Always drive slower in
these types of driving conditions and
avoid driving through large puddles
and deep-standing or flowing water.
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick
stop and could cause pulling to one
side. You could lose control of the
vehicle.
After driving through a large puddle
of water or a car/vehicle wash,
lightly apply the brake pedal until
the brakes work normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be very
cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can
build up under the vehicle's tires so
they actually ride on the water. This
can happen if the road is wet enough and you are going fast enough. When
the vehicle is hydroplaning, it has
little or no contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.
Allow extra following distance.
. Pass with caution.
. Keep windshield wiping equipment
in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper tread
depth. See Tires0270.
. 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.

There is also important loading
information on the Certification
label. It may show the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight Rating
(GAWR) for the front and rear
axle. See “Certification Label” later
in this section.
“Steps for Determining Correct
Load Limit–
1.Locate the statement "The
combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs." on your vehicle’s
placard.
2.Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3.Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lbs.
4.The resulting figure equals
the available amount of cargo
and luggage load capacity. For
example, if the "XXX" amount
equals 1400 lbs. and there
will be five 150 lb passengers
in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) =
650 lbs.)
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing
a trailer, load from your
trailer will be transferred to
your vehicle. Consult this
manual to determine how this reduces the available
cargo and luggage load
capacity of your vehicle.”
This vehicle is neither designed
nor intended to tow a trailer.
Example 1
1.Vehicle Capacity Weight
for Example 1 = 453 kg
(1,000 lbs).
2.Subtract Occupant Weight
@ 68 kg (150 lbs) × 2 =
136 kg (300 lbs).
3.Available Occupant and
Cargo Weight = 317 kg
(700 lbs).

Wheels and Tires
Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer. See the
warranty manual for information
regarding the tire warranty and
where to get service. For
additional information refer to the
tire manufacturer.
{Warning
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a
result of too much flexing.
There could be a blowout
and a serious crash. See
Vehicle Load Limits0181.
(Continued)
Warning (Continued)
.Underinflated tires pose
the same danger as
overloaded tires. The
resulting crash could cause
serious injury. Check all
tires frequently to
maintain the
recommended pressure.
Tire pressure should be
checked when the tires
are cold.
.Overinflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact —such as when
hitting a pothole. Keep
tires at the recommended
pressure.
.Worn or old tires can
cause a crash. If the tread
is badly worn,
replace them.
(Continued)
Warning (Continued)
.Replace any tires that have
been damaged by impacts
with potholes, curbs, etc.
.Improperly repaired tires
can cause a crash. Only
the dealer or an authorized
tire service center should
repair, replace, dismount,
and mount the tires.
.Do not spin the tires in
excess of 56 km/h
(35 mph) on slippery
surfaces such as snow,
mud, ice, etc. Excessive
spinning may cause the
tires to explode.

VEHICLE CARE 273
Tire Pressure
Tires need the correct amount of
air pressure to operate effectively.Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires that
do not have enough air, can
result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can result in:
.Unusual wear.
.Poor handling.
.Rough ride.
(Continued)
Caution (Continued)
.Needless damage from
road hazards.
The Tire and Loading Information
label on the vehicle indicates the
original equipment tires and the
correct cold tire inflation
pressures. The recommended
pressure is the minimum air
pressure needed to support the
vehicle's maximum load carrying
capacity. See Vehicle Load
Limits 0181.
How the vehicle is loaded affects
vehicle handling and ride comfort.
Never load the vehicle with more
weight than it was designed to
carry.
When to Check
Check the tires once a month
or more. How to Check
Use a good quality pocket-type
gauge to check the tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven for
at least three hours or no more
than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to get
the pressure measurement. If the
cold tire inflation pressure
matches the recommended
pressure on the Tire and Loading
Information label, no further
adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
inflation pressure in high, press
on the metal stem in the center of
the tire valve to release air.
Re-check the tire pressure with
the tire gauge.

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-MidEast-10287885) -
2017 - crc - 6/16/16
274 VEHICLE CARE
Put the valve caps back on the
valve stems to keep out dirt and
moisture and prevent leaks. Use
only valve caps designed for the
vehicle by GM. TPMS sensors
could be damaged and would not
be covered by the vehicle
warranty.
Tire Pressure for
High-Speed Operation
{Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts additional
strain on tires. Sustained
high-speed driving causes excessive
heat buildup and can cause sudden
tire failure. This could cause a
crash, and you or others could be
killed. Some high-speed rated tires
require inflation pressure
adjustment for high-speed
operation. When speed limits and
road conditions allow the vehicle to
be driven at high speeds, make sure(Continued)
Warning (Continued)
the tires are rated for high-speed
operation, are in excellent
condition, and are set to the correct
cold tire inflation pressure for the
vehicle load.
Vehicles with P225/45R17 90V and
225/40R18 92V size tires require
inflation pressure adjustment when
driving the vehicle at speeds of
160 km/h (100 mph) or higher. Set the
cold tire inflation pressure to
280 kPa (41 psi).
Vehicles with 225/40RF18 88W and
255/35RF18 90W or 255/35ZR18 (94Y)
and 275/35ZR18 (99Y) size tires
require inflation pressure adjustment
when driving the vehicle at speeds of
160 km/h (100 mph) or higher. Set the
cold tire inflation pressure to
300 kPa (44 psi).
Sustained operation at speeds over
160 km/h (100 mph) requires a load
limit of the driver and one passenger,
with no additional cargo. When loaded above this level, up to the GVW, do
not operate the vehicle above
160 km/h (100 mph).
Return the tires to the recommended
cold tire inflation pressure when
high-speed driving has ended. See
Vehicle Load Limits
0181 and Tire
Pressure 0273.
Tire Pressure Monitor
System
Caution
Modifications made to the Tire
Pressure Monitor System (TPMS) by
anyone other than an authorized
service facility may void
authorization to use the system.
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor the
air pressure in your vehicle's tires and
transmit tire pressure readings to a
receiver located in the vehicle.

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-MidEast-10287885) -
2017 - crc - 6/16/16
VEHICLE CARE 275
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the
inflation pressure recommended by
the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or tire
inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires
is significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to
tire failure. Under-inflation also
reduces fuel efficiency and tire tread
life, and may affect the vehicle's
handling and stopping ability.Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver's responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS
malfunction indicator is combined
with the low tire pressure telltale.
When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent the
TPMS from functioning properly.
Always check the TPMS malfunctiontelltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.
See
Tire Pressure Monitor Operation
0 275 for additional information.
Tire Pressure Monitor
Operation
This vehicle may have a Tire Pressure
Monitor System (TPMS). The TPMS is
designed to warn the driver when a
low tire pressure condition exists.
TPMS sensors are mounted onto each
tire and wheel assembly, excluding the
spare tire and wheel assembly. The
TPMS sensors monitor the air
pressure in the tires and transmit the
tire pressure readings to a receiver
located in the vehicle.

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-MidEast-10287885) -
2017 - crc - 6/16/16
276 VEHICLE CARE
When a low tire pressure condition is
detected, the TPMS illuminates the
low tire pressure warning light on the
instrument cluster. If the warning
light comes on, stop as soon as
possible and inflate the tires to the
recommended pressure shown on the
Tire and Loading Information label.
SeeVehicle Load Limits 0181.
A message to check the pressure in a
specific tire displays in the Driver
Information Center (DIC). The low tire
pressure warning light and the DIC
warning message come on at each
ignition cycle until the tires are
inflated to the correct inflation
pressure. Using the DIC, tire pressure
levels can be viewed. For additional
information and details about the DIC
operation and displays see Driver
Information Center (DIC) 0122.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the air
pressure is getting low and needs to
be inflated to the proper pressure. A Tire and Loading Information label,
attached to your vehicle, shows the
size of the original equipment tires
and the correct inflation pressure for
the tires when they are cold. See
Vehicle Load Limits
0181, for an
example of the Tire and Loading
Information label and its location.
Also see Tire Pressure 0273.
The TPMS can warn about a low tire
pressure condition but it does not
replace normal tire maintenance. See
Tire Inspection 0278, Tire Rotation
0 278 and Tires 0270.
Caution
Tire sealant materials are not all
the same. A non-approved tire
sealant could damage the TPMS
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only
the GM approved tire sealant
available through your dealer or
included in the vehicle. Factory-installed Tire Inflator Kits use
a GM approved liquid tire sealant.
Using non-approved tire sealants
could damage the TPMS sensors. See
Tire Sealant and Compressor Kit
0286
for information regarding the inflator
kit materials and instructions.
TPMS Malfunction Light and
Message
The TPMS will not function properly if
one or more of the TPMS sensors are
missing or inoperable. When the
system detects a malfunction, the low
tire warning light flashes for about
one minute and then stays on for the
remainder of the ignition cycle. A DIC
warning message also displays. The
malfunction light and DIC warning
message come on at each ignition
cycle until the problem is corrected.
Some of the conditions that can cause
these to come on are:
. One of the road tires has been
replaced with the spare tire. The
spare tire does not have a TPMS
sensor. The malfunction light and
DIC message should go off after
the road tire is replaced and the
sensor matching process is

active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
11. Shut the ignition off.
12. Set all four tires to the recommended air pressure level
as indicated on the Tire and
Loading Information label.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected for
signs of wear or damage at least
once a month.
Replace the tire if:
.The indicators at three or more
places around the tire can
be seen.
.There is cord or fabric showing
through the tire's rubber.
.The tread or sidewall is
cracked, cut, or snagged deep
enough to show cord or fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of the
size or location of the damage.
Tire Rotation
If the vehicle has non-directional
tires, they should be rotated at the
intervals specified in the
Maintenance Schedule. See
Maintenance Schedule 0307.
Tires are rotated to achieve a
uniform wear for all tires. The first
rotation is the most important.
Anytime unusual wear is noticed,
rotate the tires as soon as
possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels. If the
unusual wear continues after the
rotation, check the wheel
alignment. See When It Is Time for
New Tires 0280 and Wheel
Replacement 0282.
