1998 HONDA PRELUDE Owners Manual

Identification Numbers

Your vehicle has several identifying numbers located in various places.
The Vehicle Identification Number (VIN) is the 17-digit number your
Honda dealer uses to register your
vehicle for warranty purposes. It is also necessary for licensing and
insuring your vehicle. The easiest
place to find the VIN is on a plate
fastened to the top of the dashboard.
You can see it by looking through the windshield on the driver's side. Itis also on the Certification label at-
tached to the driver's doorjamb, and is stamped on the engine com-
partment bulkhead. The VIN is also
provided in bar code on the Certification label.

Tire Information

Tire Size Designation

A tire's sidewall is marked with a tire size designation. You will need this
information when selecting replace-
ment tires for your vehicle. The
following explains what the letters and numbers in the tire size
designation mean.
(Example tire size designation)
205/50R16 87V
205 — Tire width in millimeters.
50 — Aspect ratio. The tire's section

height as a percentage of its width.

R — Tire construction code (Radial).
16 Rim diameter in inches.
87 — Load Index, a numerical code

associated with the maximum load
the tire can carry.
V — Speed Symbol. See the speed
rating chart in this section for
additional information.

Wheel Size Designation
Wheels are also marked with important information that you need
if you ever have to replace one. The
following explains what the letters and numbers in the wheel size
designation mean.

(Example wheel size designation)

16
x 6-1/2 JJ

16 — Rim diameter in inches.
6-1/2 — Rim width in inches.
JJ — Rim contour designation.

Tire Speed Ratings
The chart below shows many of the
different speed ratings currently

being used for passenger vehicle

tires. The speed symbol is part of the

tire size designation on the sidewall
of the tire. This symbol corresponds

to that tire's designed maximum safe
operating speed.

Tire Information

Tire Pressure Adjustment For High Speed Driving
Honda strongly recommends that
you not drive faster than posted speed limits and conditions allow. If
you decide it is safe to drive at high speeds, be sure to adjust the cold tire
pressures as shown below. If you do not adjust the tire pressure, exces-sive heat can build up and cause
sudden tire failure.
Be sure to readjust the pressure for
normal driving speeds. You should
wait until the tires are cold before adjusting the tire pressure (see page
198).

DOT Tire Quality Grading (U.S. Cars)

The tires on your vehicle meet all U.S. Federal Safety Requirements.
All tires are also graded for treadwear, traction, and temperature
performance according toDepartment of Transportation (DOT) standards. The following
explains these gradings. Treadwear
The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlledconditions on a specified government
test course. For example, a tire
graded 150 would wear one and one
half (1-1/2) times as well on the
government course as a tire graded 100. The relative performance of
tires depends upon the actual condi-
tions of their use, however, and may depart significantly from the norm
due to variations in driving habits,
service practices, and differences in
road characteristics and climate.

Tire Information

Traction

The traction grades, from highest tolowest, are A, B, and C, and theyrepresent the tire's ability to stop on
wet pavement as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may
have poor traction performance.
Warning: The traction grade as- signed to this tire is based on brak-
ing (straight ahead) traction tests and does not include cornering (turning) traction.
Temperature

The temperature grades are A (the
highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor
laboratory test wheel. Sustained high temperature can cause the materialof the tire to degenerate and reduce
tire life, and excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum required by law. Warning: The temperature grade for
this tire is established for a tire thatis properly inflated and not over-
loaded. Excessive speed, underinfla-
tion, or excessive loading either separately or in combination, can
cause heat build-up and possible tire
failure.

Oxygenated Fuels

Some conventional gasolines are
being blended with alcohol or an
ether compound. These gasolines

are collectively referred to as

oxygenated fuels. To meet clean air

standards, some areas of the United

States and Canada use oxygenated

fuels to help reduce emissions.

If you use an oxygenated fuel, be
sure it is unleaded and meets the

minimum octane rating requirement.

Before using an oxygenated fuel, try

to confirm the fuel's contents. Some
states/provinces require this
information to be posted on the

pump.
The following are the EPA-approved
percentages of oxygenates:
ETHANOL (ethyl or grain alcohol)
You may use gasoline containing up to 10 percent ethanol by volume.Gasoline containing ethanol may be
marketed under the name "Gasohol."
MTBE (Methyl Tertiary Butyl Ether)
You may use gasoline containing up to 15 percent MTBE by volume.
METHANOL (methyl or wood
alcohol)

You may use gasoline containing up to 5 percent methanol by volume as
long as it also contains cosolvents and corrosion inhibitors to protect
the fuel system. Gasoline containing more than 5 percent methanol by
volume may cause starting and/or performance problems. It may alsodamage metal, rubber and plastic
parts of your fuel system. If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Fuel system damage or performance
problems resulting from the use ofan oxygenated fuel containing more
than the percentages of oxygenates
given above are not covered under

warranty.
