Inspection

1. Check the battery terminals 1 for corrosion.
2. Check the battery cables 2 for looseness.
3. Check the battery case 3 for cracks and other

damage.

4. Check the battery electrolyte level.

If the electrolyte level is excessively low, the battery
must be replaced.

5. If the battery has a built-in hydrometer, perform the

following steps:

1) Carefully clean the battery upper surface.

2) Check the hydrometer.

The hydrometer design will vary with the battery
manufacturer.

Jump Starting the Engine with a Booster Battery

The following description assumes that you are using a
booster battery mounted on a second vehicle.
The listed steps (with some minor modifications) are also
applicable if you are using a naked booster battery or
special battery charging equipment.

ELECTRICAL-BODY AND CHASSIS 8–17

Caution:
Never push or tow the vehicle in an attempt to start it.
Extensive damage to the emission system and other
vehicle parts will result.  (only catalytic converter vehicle)
Treat both the discharged battery and the booster
battery with great care when using jumper cables.
Carefully follow the procedure outlined below.
Always be aware of the dangers of sparking.

Failure to follow the following procedure can result in:

a. Serious personal injury, especially to your eyes.

b. Extensive property damage from a battery

explosion, battery acid discharge, or electrical fire.

c.

Extensive damage to the electronic components of
both vehicles.

Do not use a 24 volt booster battery.  Serious damage to
the vehicle’s electrical system and electronic components
will result.

Jump Starting Procedure

1. Set the parking brake on both vehicles.

2. If one or both vehicles is equipped with an automatic

transmission, place the selector lever in the “PARK”
position.

If one or both vehicles is equipped with a manual
transmission, place the gear shift in the “NEUTRAL”
position.

3. Turn off the ignition on both vehicles.

4. Turn off all vehicle lights and accessories.

5. Check the built-in hydrometer on the discharged

battery (If so equipped).

If there is no hydrometer indication abandon the
jump start procedure.

6. Be sure that the two vehicles are not touching.

Attach the end of one jumper cable to the booster
battery positive terminal.

7. Attach the other end of the same cable to the

discharged battery positive terminal.

8. Once again, check that the booster battery has a 12-

volt rating.

9. Attach one end of the remaining booster cable to the

booster battery negative terminal.

10. Attach the other end of the booster cable to a solid

ground (such as the air conditioner compressor
mounting bracket or the alternator mounting bracket)
in the engine room of the vehicle with the discharged
battery.

Be sure that the ground connection is at least 500
mm (20 in) from the discharged battery.

Caution:
Do not attach the booster cable to the discharged battery
negative terminal.

11. Start the engine of the vehicle with the booster

battery.

Check that all unnecessary electrical accessories are
off.

12. Start the engine of the vehicle with the discharged

battery.

13. Remove the jumper cables in the reverse order to

which they were attached.

Caution:
Be absolutely sure to remove the negative jumper cable
from the vehicle with the discharged battery first.
