1990 HONDA PRELUDE stop start

Charging System Warning Light
The charging system warning light comes on when there is a problem with the electrical charging system or when the ignition
switch is turned on with the engine not running. If the light comes
on while driving, stop the car and check to see if the alternator belt is loose or broken.
To check the belt tension, stop the engine and push with about 98N (22 Ib) of force on the middle of the belt as shown. The belt should
deflect about:
10
—
12 mm (0.4
—
0.5 in) If the engine has been running,
some engine components may
be hot enough to burn you. Keep hands away from the
radiator fan. The fan may start
automatically without warning
and run for up to 15 minutes,
even after the engine is turned
off.

NOTE:

If necessary, have the charging system checked by an authorized

Honda dealer.

Check Engine Warning Light
This light comes on for a couple of seconds each time the ignition is
turned on. It will also come on, and remain on, if there is a
malfunction in the emission control system. If the light comes on
while driving, avoid driving at high speed, and have the system checked by a Honda dealer as soon as possible.
Parking Brake/Brake Failure Warning Light
Check the brake warning light every time you start the car.
With the parking brake set, the warning light should go on when the
ignition switch is turned to II or III, With the parking brake released,
the light should go on when the ignition switch is turned to III. If the light goes on at any other time, it means the brake fluid level in the
master cylinder reservoir is too low ; add fluid and have your dealer
check for leaks and brake pad wear immediately. See page 99. BRAKE

Anti Lock Brake Warning Light (Si with ALB)
The ALB (Anti Lock Brake) warning light will come on, and remain
on, if there is a malfunction in the ALB system or when the ignition switch is turned on with the engine not running, if the light comes
on while driving, stop the car at a safe place and shut off the engine, if the light does not go out or lights again while driving, have the
system checked by an authorized Honda dealer as soon as possible.

NOTE:
The light does not indicate a failure of the normal brake system.
The light only indicates a malfunction in the ALB system. In such acase, the ALB system is automatically shut down but normal
braking capability continues.
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.

Operating Tips

For smoother operation, apply the brakes when shifting from
Neutral or Park to a forward or reverse gear.
When parking: bring the car to a stop with the foot brake, hold the brake on and shift into Park, set the hand brake and then turn off
the engine.

NOTE:

Your 4 speed automatic transmission is equipped with a torque
converter lock-up clutch. Because of this, you may notice what
feels like an extra shift as the clutch engages.
CAUTION: Shift into P only after the car has come to a complete stop.
Shift into or out of R only after the car has come to a complete

stop.

Do not "rev-up" the engine when the brake is on and the shift
lever is in D, S, 2 or R.
When stopped on a hill, use the brakes to hold your position, not the accelerator pedal.Do not shift from N or P into D, S, 2 or R when the engine is
above idle speed. Before shifting into gear, make sure your foot
is firmly on the brake pedal. Do not rest your hand on the shift lever or push the shift button
while driving.

Driving Technique

D-4th
Use the D range for normal in-town and highway driving. The car
will start off in 1st and shift automatically to 2nd, 3rd, and 4th. The
further down you push the accelerator, the later the transmission will shift and the faster the car will accelerate.

S3/S4

The "S" shift selector range changes the shift points under part
throttle acceleration, allowing the transmission to stay in each lower
gear for a longer period before automatically upshifting. With the shift selector in the "S" range, the "S3" indicator light in the dashpanel will come on and the transmission will shift from 1st to 2nd
and 3rd but not 4th. This is especially useful when climbing or
descending grades. While driving in the "S" range, the car's performance is improved but fuel economy is reduced.
Shifting the Automatic (cont'd)ProCarManuals.comMain Menu t s

While driving in the "S" range, you can select 4th gear by pushing
the "S4"
switch. Depending upon vehicle speed and throttle pedal
position, the transmission will shift to 4th gear when the switch is
pressed; the "S4" indicator light in the instrument panel will come
on. Pushing the "S4" switch again will cause the transmission to
downshift to 3rd gear In the "S3" mode. The "S4" indicator light in
the instrument panel will go out, and the "S3" light on the instrument panel will come on.
If the shift lever is moved to any other driving range, the "S4"
switch will be cancelled automatically.

NOTE:
In both the D and S modes, the transmission holds in
2nd while
you are
stopped in gear. When you start moving again, the
transmission shifts to 1st, then 2nd and so on. If rapid acceleration is necessary, depress the accelerator to the
floor; the transmission will automatically shift down according to
load and engine speed. This applies to both D and S ranges.

S4 SWITCHProCarManuals.comMain Menu t s

R-Reverse
2-2nd

Use 2nd gear
for increased engine braking when driving
downhill,
and increased power when driving uphill; also for driving on slippery
roads, and freeing the car from mud or
sand, where 1 st gear could
provide too much power and cause skidding or wheel-spin. The
maximum recommended speed in 2nd gear is:

60 mph (97
km/h)

CAUTION:

Shift into or out of reverse only after the car has come to a

complete stop; the transmission may be damaged if you shift

while the car is moving.

P-Park

CAUTION:

Use this position when starting the engine , or when parking. Shift

into Park only when the car is COMPLETELY stopped.

N — Neutral
Use when starting the engine or during prolonged idling in traffic.

Towing a Trailer (cont'd)

Towing Safety

Stopping distance will be increased when towing a trailer. For
each 10 mph (16 km/h) of speed, allow at least two car lengths between you and the vehicle ahead. Avoid sudden braking
which may cause trailer jackknifing and loss of control.
Avoid jerky starts and sudden acceleration. If your car has amanual transmission, always start out in first gear and release
the clutch at moderate engine rpm.
Avoid rapid lane changing and sharp turns. The trailer could hit your car in a tight turn. Slow down before making a turn.
Remember, the total length of your car plus trailer will require a
wider turning circle.
Crosswinds may adversely affect handling of your car and
trailer, Use the rearview mirrors frequently to warn you of approaching large vehicles that may pass you causing your car
and trailer to sway. When being passed, firmly grip the steering wheel and be prepared to reduce speed immediately but
gradually. Never increase speed. Steer straight ahead.
Towing a trailer in bad weather will magnify any difficulty in
controlling the car caused by the weather itself. Avoid sudden maneuvers: slow down and use extra caution.
Be careful when passing other vehicles. Passing requires
considerable distance because of the added weight and length

of your trailer.ProCarManuals.comMain Menu t s

CAUTION:
Before starting out, check the operation of the lights and all car/
trailer connections. After driving a short distance, stop and
recheck the lights and connections.
Reversing is difficult and requires practice. While backing-up,
the trailer may pivot off-course. To correct for this, grip the bottom of the steering wheel and move your hand to the left to
move the trailer to the left, or to the right to move the trailer to
the right. Turn the steering wheel a little at a time, and keep the
speed very low. Have someon e guide you when backing.

To help
prevent overheating of the brakes, shift into a lower
gear to make use of engine braking before descending steep or
long grades. Do not make sudden downshifts. Pay strict attention to the coolant temperature gauge when
going up hills. Because of the added load of the trailer, your car's
engine may overheat on hot days. Turning off the air conditioner
will reduce the load on the cooling system.
On cars equipped with automatic transmission. —Do not hold the car stationary on an incline by using the accelerator pedal; this can cause the transmission fluid tooverheat. Instead, use the handbrake or footbrake.
—When towing trailers, avoid high transmission fluid temperatures (caused by the transmission frequently shiftingbetween 3rd and 4th gears) by driving in S3.

NOTE:

Be sure to check state and local laws concerning maximum speed or

other driving restrictions for cars towing trailers. If you are driving
across several states, check each state's requirements before

leaving home, because restrictions may vary.

Parking with a Trailer

Whenever parking your car on an incline with a trailer attached, first
place and seat chocks at each wheel of the car and trailer. This is in

addition to the normal parking preparations of firmly applying the parking brake and placing the transmission in first or reverse
(manual transmission) or P (automatic transmission).

CAUTION:
Parking on an incline is not recommended and should be done only
if it cannot be avoided. Follow all precautions mentioned above
and turn the wheels to point towards a curb if facing downhill,
away from a curb if facing uphill. When leaving an inclined parking place, move the car slightly to unseat the chocks. Then while
keeping the foot brakes firmly applied, have an assistant remove
the chocks.ProCarManuals.comMain Menu t s

Engine Oil and Filter

Checking

Check the engine oil a couple of minutes after shutting the engine
off, with the car parked on level ground. Remove the dipstick and wipe it clean. Reinsert it all the way down, then pull it out and read
the level. The level should be between the upper and lower marks.
ENGINE OIL
FILLER CAP

Adding
If the level has dropped close to the lower mark, add oil until it is
even with the upper mark. 1 .Turn the oil filler cap counterclockwise to remove. Add oil, then check the level again. Do not overfill.
2. Reinstall the cap and twist clockwise until it stops.

CAUTION:
Be sure the oil filler cap is correctly replaced before starting the

engine.
Engine oil is a major factor affecting the performance and

service life of the engine; you should use only a premium quality

detergent oil labeled SG grade.
LOOK FOR THIS LABEL
ON THE OIL CONTAINER

Use the proper viscosity oil for the
climate in which you drive:
Some oil labels may also include additional designations of quality
such as CC or CD. However, these are acceptable only when
used together with SG.
NOTE:

5W-30 viscosity
oil is recommended for improved fuel economy.
