light HONDA PRELUDE 1990 Service Manual

Power Steering
The power steering on your car provides easy handling while parking and maneuvering in traffic, without loss of road "feel" at
highway speeds. An engine-driven hydraulic pump provides full
power assist at low speeds and decreasing assist as the car goes

faster.

CAUTION:

If the power steering system should fail, or if the engine should
stall, the car can still be steered. However, much greater effort will be required, particularly in sharp turns at low speed.

NOTE:

You may feel a slight clunk or knock when turning the wheel with
the engine off. This is a normal condition due to the design of the system.
Power Steering Fluid
Check the power steering fluid level with the engine cold and the
car parked on level ground. Make sure the fluid level is between theupper and lower marks on the reservoir. If the level has dropped
close to or below the lower mark, check for leaks before adding
fluid to the upper mark. Do not overfill.

CAUTION:

Use only genuine Honda power steering fluid. The use of other
fluids such as A.T.F. or other manufacturer's power steering fluid will damage the system. POWER STEERING

Brakes

Brake System Design
The diagonally-separated dual service brake systemis designed so half the
system will still provide
braking action if the other
half fails.However, stopping the car with only half the system will require
more pedal pressure and pedal travel than normal. Also, the distance
required to stop will be longer using only half the brake system. If
the brakes fail suddenly, downshift to a lower gear for increased engine braking, and pull off the road as soon as possible.
It is dangerous to drive your car with a problem in either the
brake electrical or hydraulic system; have your dealer check
both systems if you suspect brake trouble. Do not ride the brakes, In other words, don't put your foot on
the brake pedal unless you intend to brake. This causes excessive brake wear and can damage, or lead to loss of braking
effectiveness through overheating. Your brake lights may also
confuse drivers behind you.Driving through deep water may affect the brakes.
Check their effectiveness by pressing the brake pedal gently.If the car does not slow down at the normal rate, continue
gently applying the brakes, while maintaining a safe speed, until
they dry out and normal performance returns.
Brake Wear
Both front and rear brakes should be inspected for wear at the
intervals shown in the maintenance schedule on page 78
When the brakes require maintenance, use only genuine Honda replacement parts or their equivalent.
Brake Wear Indicators
Your car is equipped with audible brake wear indicators. When the
brake pads need to be replaced, the wear indicators will make a "screeching" sound or a high pitch chirp.

NOTE:

Due to some driving habits or climates, brakes may "squeal" when
you first apply them or when you have them partially applied; this is normal, and does not indicate excessive wear. The wear indicator
makes a "screeching" sound while the brakes are applied.ProCarManuals.comMain Menu t s

Fuse Replacement
The fuse boxes are located under the dashboard on the driver's side and on the right front fender beside the battery. The circuitsprotected by each fuse are listed on the plastic sheet in the box.
If any of your car's lights, accessories, or controls don't work,
check their fuses. If a fuse has blown, the wire inside it win be
burned through.
Checking the fuses: 1 . Turn off the ignition and all other switches.
2 . If you find a blown or possibly faulty fuse, use the fuse remover (located inside the fuse box under the dashboard) to pull the
blown fuse out of its clips.
3 . Check all other fuses as well as the one you suspect.
4 . Push in a new fuse of the same rating, and make sure it fits tightly in the clips. If it fits loosely, have your dealer fix it.If you don't have a spare, take a fuse of the same rating (or lower)
out of a circuit you may not need, like the radio or cigarette lighter. Remember to replace the borrowed fuse and the missing spares. FUSE BOX COVER

Washing

NOTE:

Retract the headlights before washing the car. However, make sure

the headlight lenses are cleaned periodically.

Rinse all loose dirt off the car by spraying it with lukewarm or cold

water. Do not use hot water.
Wash using a soft bristle brush, sponge, or cloth with water
containing a mild detergent, such as a liquid dishwashing detergent.
Remove oil, tar, tree sap, etc., with tar remover or turpentine.
Remove road salt, insects, etc., with mild detergent and lukewarm
water. Any of these substances may damage the finish if left on
painted surfaces.

Rinse the car well. Promptly wipe with a chamois or soft towel toprevent water-spotting. Do not let water or soap air-dry on painted

surfaces.
During wiping, inspect the surface for stone chips and scratches;paint them with touch-up paint so they won't rust (touch-up paint

is available through your Honda dealer).
For further instructions on corrosion protection, refer to the Rust

Prevention section on page 112.

Aluminum Alloy Wheels (Si with 4WS or ALB)
CAUTION:
Wash the wheels after driving on snowy or icy roads where salt

has been applied.

Avoid off-road driving. Brush, rocks, dirt and severe impact may
damage the wheels.
Install tire chains carefully. Improperly installed chains can cause

damage to the wheels.
Honda aluminum alloy wheels are treated with a protective
finish. Wash them with a low-phosphate detergent and sponge.
Do not use abrasive cleaners or stiff brushes. Always install aluminum wheels in sets of four. If mixed with
other types, the car's handing may be affected.

Changing a Flat Tire (cont'd)
7. Set the jack handle extension in the connector on the end of the jack and install the lug wrench/jack handle. Turn the lug wrench/jack handle clockwise until the tire is slightly off the ground.
8. Remove the lug nuts, wheel cover and wheel.
(Wheel cover is not equipped
with 4WS or ALB models)
9. Install the spare tire; and install the lug nuts hand tight.
10. Lower the car, remove the jack,
then tighten the lug nuts

securely in an "X" pattern as
shown.11. Tighten the lug nuts securely.
The recommended torque is:
110 N .
m(11 kg-m,80 Ib-ft)
If a torque wrench was not

used, ask an authorized Honda

dealer to verify the torque as
soon as possible.
12. Repai
r or replace the damaged tire as soon as you can, then
reinstall it in its original position on the car, and put the spare back
in the car.

CAUTION:

Always stow the jack, tools and tire securely to prevent them
from becoming dangerous projectiles in an accident.
NOTE:
Secure the tire and the spacer as shown in the illustration.

Jump Starting
To start a car with a dead battery, use another battery of the same voltage, and the proper jumper cables. Procedures other than those below could cause injury or
damage from battery acid spray, explosion or charging system

overload.

Never connect the jumper cable directly to the negative post of
the "dead" battery.
Never allow the two cars to touch each other.
Never allow the jumper cable clamps to touch each other.
Never lean over the battery when making connections.
Never attempt to jump start a vehicle with a frozen battery. The
battery could rupture and explode. If you suspect a frozen
battery, remove the vent caps and check the fluid. If there
seems to be no fluid, or if you see ice, do not attempt a jump
start until the fluid thaws.

CAUTION:

If jumper cables are connected backwards, the car's main fuse
may blow.
1.Turn off all lights, heater and other electrical loads, set parking
brake, and
shift transmission to Neutral or Park.
2. Use one cable to connect the positive terminal of the booster battery to the positive terminal of the "dead" battery.

Jump Starting (cont'd)
3. Use the other cable to connect the negative terminal of the booster battery to the engine at the ground cable as shown.
4.To remove the cables, reverse the above procedures exactly.
DO NOT push or tow a car to start it. The forward surge when the
engine starts could cause a collision. Also, under some conditions,
the catalytic converter could be damaged. A car equipped with an
automatic transmission cannot be started by pushing or towing.
NOTE:
After jump-starting the car, there is a possibility that the ALB
warning light may come on due to insufficient battery voltage. After
the battery is sufficiently recharged and the engine is turned off and restarted, the ALB warning light should indicate that the ALB
system is OK, by coming on for a few seconds each time the engine is started. If the light remains on after recharging, have it checked

by a Honda dealer.ProCarManuals.comMain Menu t s
