CLEAN Indicator Light
After 50 hours of cassette tape play, the light will come on as a reminder to clean the tape heads. If the light comes on and the tape
heads were not cleaned at the recommended 30 hours of usage (see maintenance section below), they should be cleaned immediately.
To reset, push the indicator for a minimum of five seconds until the light goes off.

Defective Tape Eject

The tape player includes a protection mechanism to automatically eject defective tapes (warped housing, loose label, faulty tape movement) immediately upon insertion, if a tape malfunctions while
in play, the tape direction will change back and forth and then e|ect
the cassette. Tapes ejected before play should be considered faulty and discarded; tapes ejected during play may only be unevenly
wound and could be re-usable if fully rewound, manually, outside the player.
NOTE:
The tape player may repeat cycle through the loading and unloading
motion several times in an effort to eject a faulty tape. During this
process the tape will either eject fully or rise to the loading level and
have to be pulled out manually. In either case, discard the tape; re-
use may damage the tape player.

Maintenance

The head in the cassette tape player can pick up dirt or tape
deposits each time a cassette is played. The result is low or "muddy" sound from one or both channels, as if the treble tone
control were turned all the way down. To prevent this, you should periodically clean the head with a commercially available cleaning

cassette.

As preventive maintenance, clean the head about every 30 hours of
use. If you wait until the head becomes very dirty (noticeably poor
sound), it may not be possible to remove all deposits with a simple
cleaning cassette.
The use of 120 minutes tape is not recommended.
CAUTION:
Storing cassettes out of their cases, or touching the magnetic
tape with your fingers will increase the amount of dirt that gets to

the tape head. Using low-quality "off-brand" tape will increase the
amount of tape deposits that get on the head. Both of these

practices may eventually lead to damage of the head and playing

mechanism.ProCarManuals.comMain Menu t s

Sunroof
Sunroof
To open the sunroof, push and hold the switch. To close
the sunroof, push and hold the switch. Release the switch
when the roof reaches the desired position.
Do not hold the switch on after the sunroof has fully opened or
closed, or you may damage the sunroof motor. Do not allow any part of your body to extend through the
sunroof while the vehicle is in motion. In the event of a collision
or
sudden application of the brakes, severe personal injury could

result.

To avoid the possibility of injury while closing the sunroof,

never allow
any part of your body to extend through the

opening.

CAUTION:

Operating the sunroof in severe cold or when it is covered with
snow or ice may cause damage to the sunroof.

Sunshade

As well as the sunroof, there is a sliding sunshade which you canadjust to let in light with the roof closed, or to block out light
entirely. The sunshade opens automatically as you open the sunroof.

Gasoline
For proper operation of your car's emission controls, your engine is
designed to use unleaded fuel only.

CAUTION:

Using leaded or even low-lead gasoline could damage some of your
emission controls, and also void their coverage under the emission
controls warranty.
Use gasoline from pumps labeled unleaded, with a pump octane
number of 86 or higher. The pump octane number is an average of
the Research (R) octane and Motor (M) octane numbers. Use of a
lower octane gasoline can cause persistent, heavy "SPARK
KNOCK" (a metallic rapping noise), which can lead to engine damage

if severe.
CAUTION:
If you notice steady spark knock while holding a steady speed on a
level road, try changing brands of gasoline. If the spark knock persists, consult your Honda dealer. Failure to do so is considered
misuse, and misuse is not covered under the New Car Warranty.
Occasionally you may notice light spark knock while accelerating or
driving up hills. This is no cause for concern, it simply means your engine is running at its most economical.
Gasoline Containing Alcohol
If you decide to use a gasoline containing alcohol ("gasohol"), be
sure its octane rating is at least as high as that recommended for
unleaded gasoline. There are two types of "gasohol": that
containing ethanol, and that containing methanol. Do not use
gasohol that contains more than 10% ethanol. Do not use gasoline
containing methanol (methyl or wood alcohol) that does not also contain cosolvents and corrosion inhibitors for methanol. Never use
gasoline containing more than 5% methanol, even if it hascosolvents and corrosion inhibitors.

Gasoline (cont'd)
NOTE:
Fuel system damage or vehicle performance problems resulting
from the use of such fuels is not covered under the new car warranties. Honda cannot endorse the use of fuels containingmethanol since evidence of their suitability is as yet incomplete. Before purchasing fuel from an unfamiliar station, try to confirm
whether the fuel contains alcohol; of what kind, and how much. If
you notice any undesirable operating symptoms after using a
gasoline that contains alcohol, or one that you think contains
alcohol, switch to an unleaded gasoline, as recommended on page 55.
Operation In Foreign Countries In order to comply with U.S. Federal Emissions Regulations, you
must use unleaded fuels of the recommended octane rating. These
fuels may not be available in other countries. If you intend taking your car outside the U.S. or Canada, write to American Honda
Consumer Affairs (stating the year and model of your car) at the
address below for information regarding modifications you mayneed to have done.

Fuel Filler Door and Cap
Gasoline is extremely flammable and is explosive under certain
conditions. Perform this operation in a well-ventilated area with
the engine stopped. Do not smoke or allow open flames or sparks in the area or where gasoline is stored.
The fuel filler door is opened by pulling up on the lever at the leftside of the driver's seat.
The door will lock automatically when closed; push it until it clicks.

CAUTION:

You may hear a hiss when you open the filler cap. This sound is residual pressure escaping from the fuel tank. Open the cap slowly
and remove the cap after the hissing stops. Do not overfill the tank;
fill only until the gas pump clicks off automatically and never top off.ProCarManuals.comMain Menu t s
