For additional information and
details about the DIC operation and
displays seeDriver Information
Center (DIC) on page 5‑26.
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 on page 9‑11, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10‑50. The TPMS can warn about a low
tire pressure condition but it
does not replace normal tire
maintenance. See
Tire Inspection
on page 10‑56, Tire Rotation on
page 10‑57 andTires on
page 10‑42.
Notice: 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 on page 10‑67 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 performed
successfully. See “TPMS Sensor
Matching Process” later in this
section.

Vehicle Care 10-57
.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
every 12 000 km/7,500 mi. See
Maintenance Schedule on
page 11‑3.
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 on
page 10‑59 andWheel
Replacement on page 10‑63.
Directional tires should not be
rotated. Each tire and wheel
should be used only in the
position it is in. Directional tires
will have an arrow on the tire
indicating the proper direction of
rotation or will have “left”or
“right” molded on the sidewall.
Use this rotation pattern if the
vehicle has different size tires
on the front and rear and they
are non-directional.
Different tire sizes should not be
rotated front to rear.

10-58 Vehicle Care
Use this rotation pattern when
rotating tires of the same size
installed on all four wheel
positions.
If the vehicle has a compact
spare tire, do not include it in the
tire rotation.Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure on page 10‑50
and
Vehicle Load Limits on
page 9‑11.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑53.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications on
page 12‑2.
{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.

10-60 Vehicle Care
GM's exclusive TPC Spec
system considers over a
dozen critical specifications that
impact the overall performance
of the vehicle, including brake
system performance, ride and
handling, traction control, and
tire pressure monitoring
performance. GM's TPC Spec
number is molded onto the tire's
sidewall near the tire size. If the
tires have an all-season tread
design, the TPC Spec number
will be followed by MS for mud
and snow. SeeTire Sidewall
Labeling on page 10‑45, for
additional information. GM recommends replacing
worn tires in complete sets of
four. Uniform tread depth on all
tires will help to maintain the
performance of the vehicle.
Braking and handling
performance may be adversely
affected if all the tires are not
replaced at the same time.
If proper rotation and
maintenance have been done,
all four tires should wear out at
about the same time. See
Tire
Rotation on page 10‑57 for
information on proper tire
rotation. However, if it is
necessary to replace only one
axle set of worn tires, place the
new tires on the rear axle.
Winter tires with the same speed
rating as the original equipment
tires may not be available for H,
V, W, and ZR speed rated tires.
Never exceed the winter tire's maximum speed capability when
using winter tires with a lower
speed rating.
{WARNING
Tires could explode during
improper service. Attempting
to mount or dismount a tire
could cause injury or death.
Only your dealer or authorized
tire service center should
mount or dismount the tires.
{WARNING
Mixing tires of different sizes
(other than those originally
installed on the vehicle), brands,
or types may cause loss of
control of the vehicle, resulting in
a crash or other vehicle damage.
Use the correct size, brand, and
type of tire on all four wheels.

Black plate (61,1)Cadillac ATS Owner Manual - 2013 - CRC - 10/5/12
Vehicle Care 10-61
{WARNING
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
A tire and/or wheel could fail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size,
load range, speed rating, and
construction (radial) as the
original tires.
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low-pressure warning if non-TPC
Spec rated tires are installed.
See Tire Pressure Monitor
Operation on page 10‑53. The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. See
Vehicle Load Limits
on page 9‑11, for the label
location and more information
about the Tire and Loading
Information label.
Different Size Tires and
Wheels
If wheels or tires are installed that
are a different size than the original
equipment wheels and tires, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, electronic stability control,
or All-Wheel Drive, the performance
of these systems can also be
affected.
{WARNING
If different sized wheels are used,
there may not be an acceptable
level of performance and safety
if tires not recommended for
those wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tire systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.
See Buying New Tires on
page 10‑59 andAccessories and
Modifications on page 10‑3.

Used Replacement Wheels
{WARNING
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{WARNING
If the vehicle has 225/40R18,
225/40RF18, 255/35RF18,
225/35R19, or 255/30R19 size
tires, do not use tire chains.
There is not enough clearance.
Tire chains used on a vehicle
without the proper amount of
clearance can cause damage to(Continued)
WARNING (Continued)
the brakes, suspension, or other
vehicle parts. The area damaged
by the tire chains could cause
loss of control and a crash.
Use another type of traction
device only if its manufacturer
recommends it for the vehicle's
tire size combination and
road conditions. Follow that
manufacturer's instructions.
To avoid vehicle damage, drive
slow and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the rear tires. Notice:
If the vehicle is
equipped with a tire size other
than 225/40R18, 225/40RF18,
255/35RF18, 225/35R19, or
255/30R19, use tire chains only
where legal and only when
necessary. Use low profile chains
that add no more than 12 mm
thickness to the tire tread and
inner sidewall. Use chains that
are the proper size for the tires.
Install them on the tires of the
rear axle. Do not use chains on
the tires of the front axle. Tighten
them as tightly as possible with
the ends securely fastened. Drive
slowly and follow the chain
manufacturer's instructions. If the
chains contact the vehicle, stop
and retighten them. If the contact
continues, slow down until it
stops. Driving too fast or
spinning the wheels with chains
on will damage the vehicle.
