When to Add Engine OilIf the oil is below the L mark for the L6 engine or the
cross-hatched area at the tip of the dipstick for the
V8 engine, add at least one quart/liter of the
recommended oil. This section explains what kind of oil to
use. For engine oil crankcase capacity, seeCapacities
and Specifications on page 5-121.
Notice:Do not add too much oil. If the engine has so
much oil that the oil level gets above the
cross-hatched area (F) that shows the proper
operating range for the L6 engine or above the
cross-hatched area for the V8 engine, the engine
could be damaged.

Tire Terminology and De nitions
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 Pressure
on page 5-65.
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
