Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change thevehicle's frame, bumper system,height, front end, or side sheetmetal may keep the airbag systemfrom working properly. Theoperation of the airbag system canalso be affected by changing anyparts of the front seats, safety belts,airbag sensing and diagnosticmodule, steering wheel, instrumentpanel, any of the airbag modules,ceiling or pillar garnish trim, theinside rearview mirror, front sensors,side impact sensors, or airbagwiring.
Yo u r d e a l e r a n d t h e s e r v i c e m a n u a lhave information about the locationof the airbag sensors, sensing anddiagnostic module and airbagwiring.
In addition, the vehicle has apassenger sensing system for thefront outboard passenger position,which includes sensors that are partof the passenger's seat. Thepassenger sensing system may notoperate properly if the original seat
trim is replaced with non-GMcovers, upholstery or trim, or withGM covers, upholstery or trimdesigned for a different vehicle. Anyobject, such as an aftermarket seatheater or a comfort enhancing pador device, installed under or on topof the seat fabric, could alsointerfere with the operation of thepassenger sensing system. Thiscould either prevent properdeployment of the passengerairbag(s) or prevent the passengersensing system from properlyturning off the passenger airbag(s).SeePassenger Sensing System063.
If the vehicle has rollover roof-railairbags, seeDifferent Size Tiresand Wheels0318for additionalimportant information.
If you have to modify your vehiclebecause you have a disability andhave questions about whether themodifications will affect the vehicle'sairbag system, or if you havequestions about whether the airbagsystem will be affected if the vehicle
is modified for any other reason, callCustomer Assistance. SeeCustomer Assistance Offices0366.

304 Vehicle Care
Winter Tires
This vehicle was not originallyequipped with winter tires. Wintertires are designed for increasedtraction on snow and ice-coveredroads. Consider installing wintertires on the vehicle if frequentdriving on ice or snow coveredroads is expected. See your dealerfor details regarding winter tireavailability and proper tire selection.Also, seeBuying New Tires0317.
With winter tires, there may bedecreased dry road traction,increased road noise, and shortertread life. After changing to wintertires, be alert for changes in vehiclehandling and braking.
If using winter tires:
.Use tires of the same brand andtread type on all four wheelpositions.
.Use only radial ply tires of thesame size, load range, andspeed rating as the originalequipment tires.
Winter tires with the same speedrating as the original equipment tiresmay not be available for H, V, W, Y,and ZR speed rated tires. If wintertires with a lower speed rating arechosen, never exceed the tire'smaximum speed capability.
Low-Profile Tires
Caution
Low-profile tires are more
susceptible to damage from road
hazards or curb impact than
standard profile tires. Tire and/or
wheel assembly damage can
occur when coming into contact
with road hazards like potholes,
or sharp edged objects, or when
sliding into a curb. The warranty
does not cover this type of
damage. Keep tires set to the
correct inflation pressure and
when possible, avoid contact with
curbs, potholes, and other road
hazards.
Summer Tires
Ultra High Performance SummerTires
This vehicle may come with 245/40R19 and 275/35R19 ultra highperformance summer tires. Thesetires have a special tread andcompound that are optimized formaximum dry and wet roadperformance. This special tread andcompound will have decreasedperformance in cold climates, andon ice and snow. Driving a vehiclewith ultra high performance summertires when temperatures are belowapproximately 5 °C (40 °F) is notrecommended. If driving in theseconditions, winter tires should beinstalled. SeeWinter Tires0304.
Caution
Ultra high performance summer

tire size, and date the tire was
manufactured. The TIN is
molded onto both sides of the
tire, although only one side may
have the date of manufacture.
(5) Tire Ply Material:The type
of cord and number of plies in
the sidewall and under the tread.
(6) Uniform Tire Quality
Grading (UTQG):Tire
manufacturers are required to
grade tires based on three
performance factors: treadwear,
traction, and temperature
resistance. For more information
seeUniform Tire Quality
Grading0319.
(7) Maximum Cold Inflation
Load Limit:Maximum load that
can be carried and the
maximum pressure needed to
support that load.
Tire Designations
Tire Size
The following is an example of a
typical passenger vehicle
tire size.
(1) Passenger (P-Metric) Tire:
The United States version of a
metric tire sizing system. The
letter P as the first character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association.
(2) Tire Width:The three-digit
number indicates the tire section
width in millimeters from
sidewall to sidewall.
(3) Aspect Ratio:Atwo-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item 3 of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(4) Construction Code:Aletter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Service Description:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.

of reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allow theTPMS to continue to functionproperly.
SeeTire Pressure MonitorOperation0312.
SeeRadio Frequency Statement0374.
Tire Pressure Monitor
Operation
This vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly, including the spare tireand wheel assembly. The TPMSsensors monitor the air pressure in
the tires and transmit the tirepressure readings to a receiverlocated in the vehicle.
When a low tire pressure conditionis detected, the TPMS illuminatesthe low tire pressure warning lightlocated on the instrument cluster.If the warning light comes on, stopas soon as possible and inflate thetires to the recommended pressureshown on the Tire and LoadingInformation label. SeeVehicle LoadLimits0226.
AmessagetocheckthepressureinaspecifictiremaydisplayintheDriver Information Center (DIC). Thelow tire pressure warning light andthe DIC warning message,if equipped, come on at eachignition cycle until the tires areinflated to the correct inflationpressure. Using the DIC, it may bepossible to view the tire pressure
levels. For additional informationand details about the DIC operationand displays, seeDriver InformationCenter (DIC)0108.
The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven. Thiscould be an early indicator that theair pressure is getting low andneeds to be inflated to the properpressure.
ATire and Loading Information labelshows the size of the originalequipment tires and the correctinflation pressure for the tires whenthey are cold. SeeVehicle LoadLimits0226,foranexampleoftheTire and Loading Information labeland its location. Also seeTirePressure0309.
The TPMS can warn about a lowtire pressure condition, but it doesnot replace normal tiremaintenance. SeeTire Inspection0315,Tire Rotation0315,andTires0303.

11 . P r o c e e d t o t h e l e f t r e a r t i r e ,and repeat the procedure inStep 8. The horn sounds twotimes to indicate the sensoridentification code has beenmatched to the left rear tire,and the TPMS sensor matchingprocess is no longer active.The TIRE LEARN or TIRELEARNING ACTIVE messageon the infotainment displaygoes off.
12. Turn the vehicle off.
13. Set all four tires to therecommended air pressurelevel as indicated on the Tireand 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
The tires should be rotated
every 12 000 km/7,500 mi. See
Maintenance Schedule0349.
Tires are rotated to achieve
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. SeeWhen It Is Time
for New Tires0316andWheel
Replacement0320.
Different tire sizes should not be
rotated front to rear.

Chevrolet SS Sedan Owner Manual (GMNA-Localizing-U.S.-10122752) -2017 - crc - 8/31/16
316 Vehicle Care
Use this rotation pattern if the
vehicle has different size tires
on the front and rear.
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 Pressure0309andVehicle
Load Limits0226.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation0312.
Check that all wheel nuts are
properly tightened. See“Wheel
Nut Torque”underCapacities
and Specifications0362.
{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
ascraperorwirebrushlaterto
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.
When It Is Time for New
Tires
Factors such as maintenance,temperatures, driving speeds,vehicle loading, and road conditionsaffect the wear rate of the tires.
Treadwear indicators are one way totell when it is time for new tires.Treadwear indicators appear whenthe tires have only 1.6 mm (1/16 in)or less of tread remaining. SeeTireInspection0315andTire Rotation0315.

Chevrolet SS Sedan Owner Manual (GMNA-Localizing-U.S.-10122752) -2017 - crc - 8/31/16
318 Vehicle Care
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, a n d Z R s p e e d r a t e d t i r e s .
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
acrashorothervehicledamage.
Use the correct size, brand, and
type of tire on all four wheels.
{Warning
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
Atireand/orwheelcouldfail
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.
SeeTire Pressure Monitor
Operation0312.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. SeeVehicle Load Limits
0226.
Different Size Tires and
Wheels
If wheels or tires are installed thatare a different size than the originalequipment wheels and tires, vehicleperformance, including its braking,ride and handling characteristics,stability, and resistance to rollovermay be affected. If the vehicle haselectronic systems such as antilockbrakes, rollover airbags, traction

control, electronic stability control,or All-Wheel Drive, the performanceof these systems can also beaffected.
{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.
SeeBuying New Tires0317andAccessories and Modifications0272.
Uniform Tire Quality
Grading
The following information relates
to the system developed by the
United States National Highway
Traffic Safety Administration
(NHTSA), which grades tires by
treadwear, traction, and
temperature performance. This
applies only to vehicles sold in
the United States. The grades
are molded on the sidewalls of
most passenger car tires. The
Uniform Tire Quality Grading
(UTQG) system does not apply
to deep tread, winter tires,
compact spare tires, tires with
nominal rim diameters of
10 to 12 inches (25 to 30 cm),
or to some limited-production
tires.
While the tires available on
General Motors passenger cars
and light trucks may vary with
respect to these grades, they
must also conform to federal
safety requirements and
additional General Motors Tire
Performance Criteria (TPC)
standards.
Quality grades can be found
where applicable on the tire
sidewall between tread shoulder
and maximum section width. For
example:
Treadwear 200 Traction AATemperature A
All Passenger Car Tires Must
Conform to Federal Safety
Requirements In Addition To
These Grades.
Treadwear
The treadwear grade is a
comparative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course. For example, a tire
graded 150 would wear one and
one-half (1Ω) times as well on
the government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of
their use, however, and may
depart significantly from the
