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.

The condition of the battery can be determined by checking the
test indicator. Service as required according to the label on the
battery.

Any corrosion around the positive and negative terminals should be washed off with a solution of baking soda and warm water. Dry the
terminals and then coat them with grease.
The battery gives off explosive gases; keep sparks, flames andcigarettes away. Provide adequate ventilation when charging orusing the battery in an enclosed space.
The battery contains sulfuric acid (electrolyte). Contact with skin or eyes may cause severe burns. Wear protective clothing
and a face shield.
— If electrolyte gets on your skin, flush with water.
— If electrolyte gets in your eyes, flush with water for at least
15 minutes and call a physician immediately.
Electrolyte is poisonous.
— If swallowed, drink large quantities of water or milk and follow with milk of magnesia or vegetable oil and call a physician.

System Maintenance
Run your air conditioner at least once a week for about ten minutes,
even during the off season, to lubricate the seals and the inside of

the compressor and, to verify that the system is functional.

If the air conditioner is not cooling properly, it may indicate an
undercharged system. Have your dealer check the system for leaks,
then evacuate and charge the system with refrigerant 12. Charging quantity:

850-950 g(30.1-33.6 oz)

CAUTION:

Prolonged use of an undercharged system may damage the

compressor.ProCarManuals.comMain Menu t s

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
