10-40 Vehicle Care
(C) Aspect Ratio:A two-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(D) Construction Code
:A
letter 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.
(E) Rim Diameter
:Diameter of
the wheel in inches. (F) Service Description
:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carry capacity a tire is
certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch
of the tire. Air pressure is
expressed in psi (pounds per
square inch) or kPa (kilopascal).
Accessory Weight
:This
means the combined weight
of optional accessories.
Some examples of optional accessories are, automatic
transmission, power steering,
power brakes, power windows,
power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire's height to its width.
Belt
:A rubber coated layer of
cords that is located between
the plies and the tread. Cords
may be made from steel or other
reinforcing materials.
Bead
:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire
:A pneumatic tire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline
of the tread.

10-52 Vehicle Care
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of your
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 an MS for
mud and snow. SeeTire
Sidewall Labeling
on page 10‑37
for additional information.
GM recommends replacing tires
in sets of four. This is because
uniform tread depth on all tires
will help keep your vehicle
performing most like it did when
the tires were new. Replacing
less than a full set of tires can
affect the braking and handling
performance of your vehicle. See
Tire Inspection
on page 10‑49
andTire Rotationon page 10‑49
for information on proper tire
rotation.
{WARNING
Mixing tires could cause you
to lose control while driving.
If you mix tires of different
sizes, brands, or types (radial
and bias-belted tires), the
vehicle may not handle
properly, and you could have
a crash. Using tires of different
sizes, brands, or types may
also cause damage to your
vehicle. Be sure to use the
correct size, brand, and type
of tires on all wheels. It is all
right to drive with your
compact spare temporarily, as
it was developed for use on
your vehicle. See Compact
Spare Tire
on page 10‑77.
{WARNING
If you use bias-ply tires on the
vehicle, the wheel rim flanges
could develop cracks after
many miles of driving. A tire
and/or wheel could fail
suddenly, causing a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If you must replace your
vehicle's tires with those that do
not have a TPC Spec number,
make sure they are the same
size, load range, speed rating,
and construction type (radial and
bias-belted tires) as your
vehicle's original tires.

10-92 Vehicle Care
A paper towel can be used to blot
excess moisture from the fabric or
carpet after the cleaning process.
Leather
To remove dust, a soft cloth
dampened with water can be used.
If a more thorough cleaning is
necessary, a soft cloth dampened
with a mild soap solution can be
used. Allow the leather to dry
naturally. Do not use heat, steam,
or spot lifters or spot removers,
or shoe polish on leather. Many
commercial leather cleaners and
coatings that are sold to preserve
and protect leather may
permanently change the
appearance and feel of the leather
and are not recommended. Do not
use silicone or wax-based products,
or those containing organic solvents
to clean the vehicle's interior
because they can alter the
appearance by increasing the gloss
in a non-uniform manner.
Instrument Panel, Vinyl, and
Other Plastic Surfaces
To remove dust, a soft cloth
dampened with water can be used.
If a more thorough cleaning is
necessary, a clean soft cloth
dampened with a mild soap solution
can be used to gently remove dust
and dirt. Never use spot lifters or
removers on plastic surfaces.
Many commercial cleaners and
coatings that are sold to preserve
and protect soft plastic surfaces
may permanently change the
appearance and feel of the interior
and are not recommended. Do not
use silicone or wax-based products,
or those containing organic solvents
to clean the vehicle's interior
because they can alter the
appearance by increasing the gloss
in a non-uniform manner.Some commercial products may
increase gloss on the instrument
panel. The increase in gloss may
cause annoying reflections in the
windshield and even make it difficult
to see through the windshield under
certain conditions.
Care of Safety Belts
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them. In
a crash, they might not be able to
provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.

Vehicle Data
Recording and
Privacy
Your GM vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven.
For example, your vehicle uses
computer modules to monitor and
control engine and transmission
performance, to monitor the
conditions for airbag deployment
and deploy airbags in a crash and,
if so equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store
data to help your dealer/retailer
technician service your vehicle.
Some modules may also store data
about how you operate the vehicle,
such as rate of fuel consumption or
average speed. These modules may
also retain the owner’s personal
preferences, such as radio pre-sets,
seat positions, and temperature
settings.
Event Data Recorders
This vehicle has an Event Data
Recorder (EDR). The main purpose
of an EDR is to record, in certain
crash or near crash-like situations,
such as an airbag deployment or
hitting a road obstacle, data that will
assist in understanding how a
vehicle's systems performed. The
EDR is designed to record data
related to vehicle dynamics and
safety systems for a short period of
time, typically 30 seconds or less.
The EDR in this vehicle is designed
to record such data as:
.How various systems in your
vehicle were operating
.Whether or not the driver and
passenger safety belts were
buckled/fastened
.How far, if at all, the driver was
pressing the accelerator and/or
brake pedal
.How fast the vehicle was
traveling
