1990 HONDA PRELUDE check engine

Speedometer

The speed is indicated in miles per hour (outside scale) and
kilometers per hour (inside).

Odometer

The numbers on the odometer indicate miles.
The odometer registers total distance traveled, and serves as your
guide for determining when periodic maintenance is due. Federal law makes it illegal to alter the odometer of any motor vehicle with the
intent to change the number of miles indicated.

Trip Meter
The numbers on the trip meter indicate miles.
The trip meter can be returned to zero by pushing in the resetbutton. Use it for checking fuel consumption or distance traveled per trip.

Tachometer
The tachometer indicates engine speed in revolutions per minute.The beginning of the RED ZONE indicates the maximum allowable
engine R.P.M. Do not run the engine with the tachometer indicator
needle in the RED ZONE.

Fuel Gauge
FUEL TANK CAPACITY: 60 l (15.9 US gal, 13.2 Imp gal)
As a convenience, the gauge continues to show the same fuel level as when the ignition was last on. After refueling, the gauge will
slowly change to the new fuel level when the ignition is switched on.
When the needle first indicates E (empty), you have a usable reserve left in the tank of about:
4 l
(1.1
US gal, 0,9 Imp gal)
Coolant Temperature GaugeCAUTION:
The needle should stay within the white range. If the needle reaches the red line at "H" (Hot), pull safely off the road, stop the
engine and check the coolant level in the reserve tank on the passenger side of the radiator under the hood.
Do not remove the radiator cap when the engine is hot. The
coolant is under pressure and may blow out and scald you.

Warning and Indicator Lights (cont'd)

Oil Pressure Warning Light

A severe fluctuation in engine oil pressure will cause this light to
flash on and off. You should stop as soon as possible, check the oil level, and add oil if necessary.
The oil pressure warning light will come on, and remain on, if there is insufficient oil pressure or when the ignition switch is turned on
with the engine not running. If the light should stay on while driving,
get the car off the road as soon as you can, turn the engine off and
check the engine oil level (see page 83).
Even if the oil level is correct, the engine should be checked by a
Honda dealer before the car is driven again.

NOTE:

The oil pressure warning light will only light as a result of low oil pressure. It is not directly an oil level indicator.
CAUTION:
Running the engine while the oil pressure warning light is on
constantly may cause immediate and severe engine damage.
Cruise Control Indicator Light
When the cruise control system is on, this indicator light is on (see
page 35 and 36).

Fuel Reserve Warning Light

If the warning light glows, it means you should refuel, because the
tank contains less than:
10 l (2.6 US gal, 2.2 Imp gal) CRUISE

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

Warning and indicator Lights (cont'd)
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.

Fuel vapor is extremely hazardous under certain conditions.
Always stop the engine before refueling, and never refuel near
sparks or open flames.

CAUTION:

When reinstalling the fuel cap, be sure both tabs on the cap are engaged in the slots of the filler neck and turn the cap until it stops.
If you replace the cap, use only a genuine Honda replacement part
or Its equivalent. Failure to use the proper part could cause serious
fuel system problems.
How to Improve Your Gas Mileage:
Drive at a smooth, steady pace to avoid unnecessary
decelerations and stops — accelerating back to speed uses more
fuel.
Plan trips to avoid rush hour traffic if possible.Make sure the parking brake is completely released.
Consolidate trips whenever possible.
Keep vehicle weight to a minimum by removing unnecessary
items from the luggage area.
Whenever possible, use fresh air from the dash vents to keep
cool when driving; open windows, or use of the air conditioningboth affect fuel economy.
Keep the tires adjusted to the recommended pressure.
Tire Pressure (measured cold)

Front: 195 kPa (28 psi)
Rear: 180 kPa (26 psi)
195 kPa (28 psi) : (Si with 4WS)

Condition of Your Car

You can only get maximum fuel economy if your car is in top running condition. Have all required maintenance done at theproper intervals. Check tire pressures and tire wear frequently. If
tire wear is uneven, have the alignment checked by your Honda dealer. Proper alignment saves gasoline and prolongs tire life.

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
