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 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 Tire 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. SeeInflation - Tire Pressureon
page 7!65.
Curb Weight: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.

First Engine Oil Change After Every
160 000 km/100,000 Miles
.Automatic transmission fluid and filter change(normal service). SeeAutomatic TransmissionFluid on page 7!24.
.Four!wheel drive only: Transfer case fluid change(normal service). Check vent hose at transfer casefor kinks and proper installation. Check to be surevent hose is unobstructed, clear, and free ofdebris. During any maintenance, if a power washeris used to clean mud and dirt from the underbody,care should be taken to not directly spray thetransfer case output seals. High pressure watercan overcome the seals and contaminate thetransfer case fluid. Contaminated fluid willdecrease the life of the transfer case and shouldbe replaced.

Recommended Fluids and
Lubricants
Fluids and lubricants identified below by name, partnumber, or specification can be obtained from yourdealer/retailer.
UsageFluid/Lubricant
Engine Oil
The engine requires a special engineoil meeting GM Standard GM4718M.Oils meeting this standard can beidentified as synthetic, and shouldalso be identified with the AmericanPetroleum Institute (API) Certified forGasoline Engines starburst symbol.However, not all synthetic API oilswith the starburst symbol will meetthis GM standard. Look for and useonly oil that meets GM StandardGM4718M. For the proper viscosity,seeEngine Oil on page 7!17.
