wheel HONDA PRELUDE 1992 Owner's Manual

The Braking System

Your Honda is equipped with disc brakes at all four wheels. The
braking system is power-assisted to
reduce the effort needed on the
brake pedal.
Put your foot on the brake pedal
only when you intend to brake.
Resting your foot on the pedal
keeps the brakes applied lightly,
causing them to build up heat. Heat
build-up can reduce how well your
brakes work. It also keeps your
brake lights on all the time, confusing drivers behind you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their effective-
ness. Use the engine to assist the
brakes by downshifting to a lower
gear and taking your foot off the
accelerator pedal. Check your brakes after driving
through deep water. Apply the
brakes moderately to see if they feel normal. If not, apply them
gently and frequently until they do. Since a longer distance is needed to
stop with wet brakes, be extra
cautious and alert in your driving.

Brake Wear Indicators

All four brakes have audible brake
wear indicators. When the brake pads need re-placing, you will hear a distinctive
metallic "screeching" sound when
you apply the brakes. If you do not
have the brake pads replaced, they
will begin screeching all the time.
Your brakes may sometimes squeal
or squeak when you apply them
lightly. Do not confuse this with the
brake wear indicators. They make a very audible "screeching".
Brake System Design

The hydraulic system that operates
the brakes has two separate cir- cuits. Each circuit works diago-
nally across the car (the left-front
brake is connected with the right-
rear brake, etc.). If one circuit
should develop a problem, you will
still have braking at two wheels.

The Braking System

If this happens, you will immediate-
ly notice that the brake pedal goes
down much farther and you need to press on it much harder. A much
longer distance will be needed to stop the car.
Slow the car by downshifting to a
lower gear and removing your foot
from the accelerator pedal. Pull to
the side of the road as soon as it is
safe. Because of the longer stop-
ping distance needed, brake system
failure is very hazardous. It is best
to have your car towed, but if you
must drive the car in this condition,
be extremely cautious. Have your car repaired as soon as possible.
Anti-lock Brakes

The Prelude Si and Si 4WS models
in
the U.S. and SR and SR 4WS
models in Canada have an Anti-
lock Brake System (ABS) as standard equipment.
ABS helps you maintain steering
control. It does this by helping you
to prevent the wheels from locking
up and skidding.
The ABS is always "On". It
requires no special effort or driving
technique. You will feel a pulsation
in the brake pedal when the ABS

activates.

Activation varies with the amount of traction your tires have. On drypavement, you will need to press on
the brake pedal very hard before
you feel the pedal
pulsation that
means the ABS has activated.
However, you may feel the ABS
activate immediately if you are
trying to stop on snow or ice. Under all conditions, the ABS is helping to
prevent the wheels from locking so
you can retain steering
control.
You should continue to press on the
brake pedal with the same force.
You may feel a slight movement of
the brake pedal just after you start
the engine. This
is
the ABS

working.

The Braking System, Four Wheel Steering

The ABS is self-checking. If
anything goes wrong, the ABS indi-
cator on the instrument panel
comes on (see page 34 ). This means
the Anti-lock function of the brak-
ing system has shut down. The
brakes still work like a convention-
al system, providing normal stop- ping ability. You should have the
dealer inspect your car as soon as

possible.
The ABS works by comparing the
speed of the wheels. When re-
placing tires, use the same size
originally supplied with the car.
Tire size and construction can
affect wheel speed and may cause
the system to work inconsistently.
A car with ABS may require a
longer distance to stop on loose or
uneven surfaces than an equivalent
car without Anti-lock. The ABS
cannot make up for road conditions
or bad judgment. It is still yourresponsibility to drive at reasonable
speeds for weather and
traffic
conditions, and to leave a margin of

safety.

For a technical description of the
Anti-lock brake system hardware,
refer to page 208 . Four Wheel Steering

The Si 4WS and SR 4WS models

feature an electronically controlled

system that steers the rear wheels

as you steer the front wheels.

It uses the car's speed, angle of the

front wheels, and the rate that you

turn the steering wheel to steer the

rear wheels in the appropriate
direction and angle.

Four Wheel Steering, Driving in Bad Weather

At very slow speeds, the rear
wheels steer in the opposite direction to the front wheels. This
helps in maneuvers such as parallelparking and U-turns.
At higher speeds, the rear wheels
first steer in the same direction as the front wheels. This aids with
changing lanes. As you turn the
steering wheel more, the rear
wheels return to straight ahead and
then steer in the opposite direction
to the front wheels. This givesimproved handling when going
around curves at highway speeds. The rear wheels return to the
straight ahead position when you
turn off the engine. They also
return to straight ahead if you sit
still for more than two minutes
with the engine running. They
return to steering mode as soon as
you move the steering wheel or
start to drive away.
The 4WS system is self-checking.
If it detects a problem anywhere in
the system, it turns on the 4WS indicator on the instrument panel
(see page 35) and points the rear
wheels straight ahead. Your car
will then drive like a conventional car without 4WS.
Driving in Bad Weather

Rain, fog, and snow conditions re-
quire a different driving technique
because of reduced traction and
visibility. Keep your car well- maintained and exercise greater
caution when you need to drive in
bad weather. The cruise control
should not be used in these condi-

tions.

Driving in Bad Weather

Driving Technique — Always
drive slower than you would in dry
weather. It takes your car longer to react, even in conditions that may
seem just barely damp. Apply
smooth, even pressure to all the
controls. Abrupt steering wheel
movements or sudden, hard appli-
cation of the brakes can cause loss
of control in wet weather. Be extra
cautious for the first few miles of
driving while you adjust to the change in driving conditions. This
is especially true in snow. A person
can forget some snow-driving tech- niques during the summer months.
Practice is needed to relearn those

skills.

Exercise extra caution when
driving in rain after a long dry spell.
After months of dry weather, the
first rains bring oil to the surface of
the roadway, making it slippery. Visibility — Being able to see
clearly in all directions and being
visible to other drivers are impor-
tant in all weather conditions. This is more difficult in bad weather. To
be seen more clearly during day-
light hours, turn on your headlights.
Inspect your windshield wipers and
washers frequently. Keep the wind- shield washer reservoir full of the

proper fluid. Replace the wind-

shield wiper blades if they start to
streak the windshield or leave parts
unwiped. Use the defrosters and air conditioner to keep the windows
from fogging up on the inside (see
page 73).
Traction — Check your tires
frequently for wear and proper pressure. Both are important in
preventing "hydroplaning" (loss of
traction on a wet surface). In the
winter, mount snow tires on all four
wheels for the best handling.
Watch road conditions carefully, they can change from moment to
moment. Wet leaves can be as slip-
pery as ice. "Clear" roads can have
patches of ice. Driving conditions
can be very hazardous when the
outside temperature is near freez-
ing. The road surface can become
covered with areas of water pud-
dles mixed with areas of ice, so
your traction can change without

warning.

Be careful when downshifting. If
traction is low, you can lock up the
drive wheels for a moment and
cause a skid.

Towing a Trailer

Driving

When parking your car and trailer,
especially on a hill, be sure to
follow all the normal precautions.
Turn your front wheels into the curb, set the parking brake firmly,
and put the transmission in 1st or
Reverse (5-speed) or Park (auto-
matic). In addition, place wheel chocks at each of the trailer's tires.
Backing up with a trailer is diffi-
cult and takes practice. Drive
slowly, make small movements
with the steering wheel, and havesomeone stand outside to guide you.
Grip th e
steering wheel on the
bottom (rather than the usual posi- tion near the top). Move your hand
to the left to get the trailer to move
to the left, and right to move the

trailer right.ProCarManuals.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.

Replacing Tires

The tires that came with your Honda were selected to match the
performance capabilities of the car
and provide the best combination of
handling, ride comfort, and long life.
You should replace them with
radial tires of the same size, load
range, and speed rating. Mixing
radial and bias-ply or bias-belted tires on your car can reduce its
braking ability, traction, and
steering accuracy.
It is best to replace all four tires at
the same time. If that is not possi-
ble or necessary, then replace the two front tires or the two rear tires
as a pair. Replacing just one tire
can seriously affect your car's han-

dling.

If you ever need to replace a wheel,
make sure you use the same wheel
that originally came on your Honda.
Replacement wheels are available
at your Honda dealer. Wheels and Tires

DOT Tire Quality Grading

(US Cars)

The tires on your car meet all U.S.
Federal Safety Requirements. All
tires are also graded for treadwear,

traction, and temperature perform-
ance according to Department 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 con-

trolled conditions on a specified

government test course. For exam-

ple, 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 per-

formance of tires depends upon the

actual conditions of their use, how-

ever, and may depart significantly

from the norm due to variations in

driving habits, service practices

and differences in road character-

istics and climate.

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.
