Supplemental Restraint System

System Service Precautions
Do not modify your steering wheel
or any other part of the supple-
mental restraint system. Modifica-
tions could make the system inef-
fective.
Do not tamper with the system
components or wiring. This could cause the airbag to inflate inadver-
tently, possibly injuring someone
very seriously.
Tell anyone who works on your car
that you have a supplemental
restraint system. Failure to follow
the procedures and precautions in
the official Honda service manualcould result in personal injury or
damage to the system.
Scrapping an entire car that has an

uninflated airbag can be dangerous.

Get assistance from a Honda dealer

if your car must be scrapped.
If you sell your car, please be sure
to tell the new owner that the car

has a supplemental restraint sys-

tem. Alert them to the information

and precautions in this part of the

owner's manual.

Fuel Economy

The condition of your car and your
driving habits are the two most
important things that affect the
fuel mileage you get.

Vehicle Condition

Always maintain your car accord-
ing to the maintenance schedule.
This will keep it in top operating
condition.
An important part of that mainte-
nance is the Periodic Checks
(see page
133). For example an
underinflated tire causes more "rolling resistance," which uses
fuel. It also wears out faster, so check the tire pressure at least

monthly. In winter, the build-up of

snow on your car's underside adds

weight and rolling resistance.

Frequent cleaning helps your fuel

mileage and reduces the chance of

corrosion.
Driving
Habit
s

You can improve fuel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more fuel. Always
drive in the highest gear that al-
lows the engine to run and acceler-
ate smoothly. Depending on traffic
conditions, try to maintain a con-
stant speed. Every time you slow
down and speed up, your car uses
extra fuel. Use the cruise control,
when appropriate, to increase fuel
economy.

A cold engine uses more fuel than a
warm engine. It is not necessary to "warm-up" a cold engine by letting
it idle for a long time. You can
drive away in about a minute, no
matter how cold it is outside. The
engine will warm up faster, and you
get better fuel economy. To cut
down on the number of "cold starts,"
try to combine several short trips
into one. The air conditioner puts an extra
load on the engine which makes it
use more fuel. Turn off the A/C to
cut down on air conditioner use.
Use the flow-through ventilation
when the outside air temperature is moderate.

Maintenance

Regularly maintaining your Honda
is the best way to protect your investment. You will be rewarded
with safer, more economical,
trouble-free driving. This section
lists items that need to be checked
regularly and explains how to check them. It also details some
simple maintenance tasks you can

do yourself. The maintenance

schedules for normal and severe
driving conditions show you when
these things need to be done.
If you are interested in how to per-
form more complex maintenance
on your Honda, you can purchase
the Service Manual. See page 221 for information on how to
obtain a copy, or see your Honda

dealer.

Engine Belts, Tires

Engine Belts

Check the condition of the two
engine belts. Examine the edges of
each belt for cracks or fraying.
Check the tension of each belt by pushing on it with your thumb
midway between the pulleys.
The belts should have the following "play" or deflection.
Alternator belt:
10.0 — 12.0 mm (0.39 — 0.47 in)

Power steering belt:
13.5 — 16.5
mm
(0.53
—
0.65 in)
If you see signs of wear or loose-

ness, have your dealer adjust or

replace the belts. Your dealer will
check these belts as part of the

normal scheduled maintenance.
Tires

Check the inflation and condition
of your car's tires at least once a

month.

Inflation

Check the pressure in the tires
when they are cold. This means the car has been parked for at least
three hours. If you have to drive
the car before checking the tire
pressure, the tires can still be
considered "cold" if you drive less than one mile.
If you check the pressure when the
tires are hot (the car has been
driven several miles), you will see
readings 28 to 41 kPa (0.3 to 0.4
kg/cm2, 4 to 6 psi) higher than the
cold reading. This is normal. Do not
let air out to match the specified
cold pressure. The tire will be

underinflated.

Maintenance
POWER STEERING BELT

Tires

The correct cold tire pressures are:
(US: S, Canada: S)
205 kPa (2.1 kg/cm2, 30 psi)

(US: Si, Si 4WS, Canada: SR, SR 4WS)

220 kPa (2.2 kg/cm2, 32 psi)

Compact spare:

415 kPa(4.15 kg/cm2, 60 psi)

These pressures are also given on
the tire information label on the driver's door jamb. Remember to
check the pressure in the spare tire
at the same time. You should get your own tire
pressure gauge and use it at all
times. That makes it easier for you
to tell if a pressure loss is caused by
a tire problem and not a variation
between gauges.
Keeping the tires properly inflated
provides you with the best combi-
nation of riding comfort, handling
and tread life. Underinflated tires
wear unevenly, reduce you car's
handling, and are more likely to fail
because of higher temperatures.
Overinflated tires make your car
ride more harshly, are more prone
to damage from road hazards, and
wear unevenly.
Inspection

Every time you check inflation, you
should also examine the tires for
damage, foreign objects, and wear.
You should look for:
Bumps or bulges in the tread or
side of the tire. Replace the tire if
you find either of these condi-
tions. Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see fabric or cord.
Excessive tread wear.

Maintenance

TIRE INFORMATION LABELProCarManuals.comMain Menu Table of Contents s t

Tires

Your car's tires have wear indica-
tors molded into the tread. When
the tread wears down to that point,
you will see a 12.7 mm (1/2 inch)
wide band running across the tread.
This shows there is less than 1.6 mm (1/16 inch) of tread left on the
tire. A tire that is this worn gives
very little traction on wet roads.
You should replace the tire if you
can see the tread wear indicator in
three or more places around the

tire.
Maintenance

In additio n
to proper inflation,
correct wheel alignment helps to
decrease tire wear. You should get your car's wheel alignment check-
ed every 12 months or 24,000 km
(15,000 miles).
The tires were properly balanced
by the factory. They may need to
be rebalanced at some time before
they are worn out. Have your
dealer check the tires if you feel a
consistent vibration while driving.
A tire should always be rebalanced
if it is removed from the wheel.
Make sure the installer balances
the wheels when you have new
tires installed. This increases riding
comfort and tire life.
Tire Rotation

To help increase tire life and
distribute wear more evenly, you
should have the tires rotated every 12,000 km (7,500 miles). Move the
tires to the positions shown in the
chart each time they are rotated.

Tires

Traction

The traction grades, from highest
to lowest, are A, B, and C, and they
represent 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
material of 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
that is properly inflated and not

overloaded. Excessive speed,

underinflation, or excessive loading.
either separately or in combination,
can cause heat build-up and
possible tire failure.
