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. See Inflation - Tire Pressure
on
page 6‑71
.
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.

Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). SeeTire Inspection
and Rotation on page 6‑78.
Scheduled Maintenance
When the Change Engine Oil Soon
Message Displays
Change engine oil and filter. See Engine Oilon
page 6‑18. An Emission Control Service.
When the Change Engine Oil Soon message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset. Your
dealer/retailer has trained service technicians who will
perform this work and reset the system. If the engine oil
life system is reset accidentally, service the vehicle
within 5 000 km/3,000 miles since the last service. Reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 6‑20. When the Change Engine Oil Soon message displays,
certain services, checks, and inspections are required.
The services described for Maintenance
Ishould be
performed at every engine oil change. The services
described for Maintenance IIshould be
performed when:
.Maintenance Iwas performed the last time the
engine oil was changed.
.It has been 10 months or more since the Change
Engine Oil Soon message has displayed or since
the last service.

First Engine Oil Change After Every
160 000 km/100,000 Miles
.Automatic transmission fluid change (normal
service). SeeAutomatic Transmission Fluidon
page 6‑24.
.Transfer case fluid change (normal service). Check
vent hose at transfer case for kinks and proper
installation. Check to be sure vent hose is
unobstructed, clear, and free of debris. During any
maintenance, if a power washer is used to clean
mud and dirt from the underbody, care should be
taken to not directly spray the transfer case output
seals. High pressure water can overcome the seals
and contaminate the transfer case fluid.
Contaminated fluid will decrease the life of the
transfer case and should be replaced.
.Spark plug replacement and spark plug wires
inspection. An Emission Control Service.
First Engine Oil Change After Every
240 000 km/150,000 Miles
.Engine cooling system drain, flush, and refill,
cooling system and cap pressure check, and
cleaning of outside of radiator and air conditioning
condenser (or every 5 years, whichever occurs
first). SeeEngine Coolant
on page 6‑29.An
Emission Control Service.
.Engine accessory drive belt inspection for fraying,
excessive cracks, or obvious damage and
replacement, if needed. An Emission Control
Service.
