Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire pressing
outward on each square inch of the tire. Air pressure
is expressed in pounds per square inch (psi) or
kilopascal (kPa).
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.
Cold Ination Pressure:The amount of air pressure in
a tire, measured in pounds per square inch (psi) or
kilopascals (kPa) before a tire has built up heat
from driving. SeeInation - Tire Pressure on page 5-59.Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment including
the maximum capacity of fuel, oil, and coolant, but
without passengers and cargo.
DOT Markings:A code molded into the sidewall of a
tire signifying that the tire is in compliance with the
U.S. Department of Transportation (DOT) motor vehicle
safety standards. The DOT code includes the Tire
Identification Number (TIN), an alphanumeric designator
which can also identify the tire manufacturer, production
plant, brand, and date of production.
GVWR:Gross Vehicle Weight Rating, seeLoading
Your Vehicle on page 4-30.
GAWR FRT:Gross Axle Weight Rating for the front
axle, seeLoading Your Vehicle on page 4-30.
GAWR RR:Gross Axle Weight Rating for the rear axle,
seeLoading Your Vehicle on page 4-30.
Intended Outboard Sidewall:The side of an
asymmetrical tire, that must always face outward
when mounted on a vehicle.
Kilopascal (kPa):The metric unit for air pressure.
Light Truck (LT-Metric) Tire:A tire used on light duty
trucks and some multipurpose passenger vehicles.

Spare Tire
Your vehicle, when new, had a fully inflated spare tire.
A spare tire may lose air over time, so check its
inflation pressure regularly. SeeInation - Tire Pressure
on page 5-59andLoading Your Vehicle on page 4-30
for information regarding proper tire inflation and loading
your vehicle. For instructions on how to remove,
install or store a spare tire, seeRemoving the Flat Tire
and Installing the Spare Tire on page 5-75and
Storing a Flat or Spare Tire and Tools on page 5-82.
Your vehicle may have a different size spare tire
than the road tires originally installed on your vehicle.
This spare tire was developed for use on your vehicle,
so it is all right to drive on it.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare
tire is correctly inflated. Have the damaged or flat road
tire repaired or replaced as soon as you can and
installed back onto your vehicle. This way, a spare tire
will be available in case you need it again.
Do not mix tires and wheels of different sizes, because
they will not fit. Keep your spare tire and its wheel
together. If your vehicle has a spare tire that does not
match your vehicle’s original road tires and wheels in size
and type, do not include the spare tire in the tire rotation.
Appearance Care
Cleaning the Inside of Your Vehicle
Your vehicle’s interior will continue to look its best if
it is cleaned often. Although not always visible, dust
and dirt can accumulate on your upholstery. Dirt can
damage carpet, fabric, leather, and plastic surfaces.
Regular vacuuming is recommended to remove particles
from your upholstery. It is important to keep your
upholstery from becoming and remaining heavily soiled.
Soils should be removed as quickly as possible. Your
vehicle’s interior may experience extremes of heat that
could cause stains to set rapidly.
Lighter colored interiors may require more frequent
cleaning. Use care because newspapers and garments
that transfer color to your home furnishings may also
transfer color to your vehicle’s interior.
When cleaning your vehicle’s interior, only use cleaners
specifically designed for the surfaces being cleaned.
Permanent damage may result from using cleaners on
surfaces for which they were not intended. Use glass
cleaner only on glass. Remove any accidental over-spray
from other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.

If you want to purchase service information, seeService
Publications Ordering Information on page 7-16.
Owner Checks and Services on page 6-9tells you what
should be checked, when to check it, and what you can
easily do to help keep your vehicle in good condition.
The proper replacement parts, fluids, and lubricants to
use are listed inRecommended Fluids and Lubricants
(Gasoline Engine) on page 6-13andNormal
Maintenance Replacement Parts on page 6-15. When
your vehicle is serviced, make sure these are used.
All parts should be replaced and all necessary repairs
done before you or anyone else drives the vehicle.
We recommend the use of genuine GM parts.
Scheduled Maintenance
(Gasoline Engine)
This maintenance section applies to vehicles with a
gasoline engine. If your vehicle has a diesel engine, see
the maintenance schedule section in the DURAMAX
®
Diesel Engine Supplement.
When the change engine oil light comes on, it means
that service is required for your vehicle. Have your
vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if you are
driving under the best conditions, the engine oil life
system may not indicate that vehicle service is necessary
for over a year. However, your engine oil and filter must
be changed at least once a year and at this time thesystem must be reset. Your GM Goodwrench
®dealer has
GM-trained service technicians who will perform this work
using genuine GM parts and reset the system.
If the engine oil life system is ever reset accidentally,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System (Gasoline Engine) on page 5-16
for information on the Engine Oil Life System and
resetting the system.
When the change engine oil light appears, certain
services, checks, and inspections are required.
Required services are described in the following for
“MaintenanceI” and “MaintenanceII.” Generally, it is
recommended that your first service be MaintenanceI,
your second service be MaintenanceII, and that you
alternate MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.
MaintenanceI— Use MaintenanceIif the change
engine oil light comes on within 10 months since
the vehicle was purchased or MaintenanceIIwas
performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message comes on
10 months or more since the last service or if the
message has not come on at all for one year.
