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, specially to your eyes.

b. Extensive property damage from a battery explosion,

battery acid discharge, or electrical file.

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 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 Be sure that the two vehicles are not touching.

Attach the end of one jumper cable to the booster battery

positive terminal.

6 Attach the other end of the same cable to the discharged

battery positive terminal.

7. Once again, check that the booster battery has a 12 volt

rating.

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

booster battery negative terminal.

9. 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.

10.Be sure that the ground connection is at least 500 mm (20

in) from the discharged battery.
