68 Seats and Restraints
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.

226 Driving and Operating
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.
Tire and Loading Information
Label
Label Example
Avehicle-specificTireand
Loading Information label is
attached to the vehicle's center
pillar (B-pillar). The Tire and
Loading Information label shows
the number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading
Information label also shows the
tire size of the original
equipment tires (3) and the
recommended cold tire inflation
pressures (4). For more
information on tires and inflation
seeTires0303andTire
Pressure0309.
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

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

F). Always store ultra high
performance summer tires
indoors and at temperatures
above -7 °C (20 °F) when not in
use. If the tires have been
subjected to -7 °C (20 °F) or less,
let them warm up in a heated
space to at least 5 °C (40 °F) for
24 hours or more before being
installed or driving a vehicle on
which they are installed. Do not
apply heat or blow heated air
directly on the tires. Always
inspect tires before use. SeeTire
Inspection0315.
Tire Sidewall Labeling
Useful information about a tire is
molded into its sidewall. The
examples show a typical
passenger tire sidewall.
Passenger (P-Metric) Tire Example
(1) Tire Size:The tire size is a
combination of letters and
numbers used to define a
particular tire's width, height,
aspect ratio, construction type,
and service description. See the
“Tire Size”illustration later in this
section for more detail.
(2) TPC Spec (Tire
Performance Criteria
Specification):Original
equipment tires designed to
GM's specific tire performance
criteria have a TPC specification
code molded onto the sidewall.
GM's TPC specifications meet or
exceed all federal safety
guidelines.
(3) DOT (Department of
Transportation):The
Department of Transportation
(DOT) code indicates that the
tire is in compliance with the
U.S. Department of
Transportation Motor Vehicle
Safety Standards.
DOT Tire Date of
Manufacture:The last four
digits of the TIN indicate the tire
manufactured date. The first two
digits represent the week
(01-52) and the last two digits,
the year. For example, the third
week of the year 2010 would
have a four-digit DOT date
of 0310.
(4) Tire Identification Number
(TIN):The letters and numbers
following the DOT code are the
Tire Identification Number (TIN).
The TIN shows the
manufacturer and plant code,

Chevrolet SS Sedan Owner Manual (GMNA-Localizing-U.S.-10122752) -2017 - crc - 8/31/16
306 Vehicle Care
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.
