before proceeding. If no water is available, remove the caps<br />
and cover the filler openings with a cloth. After jump starting<br />
the vehicle, dispose of the cloth.<br />
WARNING! If you do not cover the filler openings<br />
on the battery, electrolyte could boil out of the<br />
openings and hurt someone or damage the vehicle.<br />
Replace caps securely if the battery has the<br />
full level of electrolyte. If the electrolyte is low<br />
and no water is available, cover with a cloth.<br />

WARNING! When connecting jumper cables,<br />
make sure they can not get caught in any moving<br />
parts in the engine compartment. You could<br />
be seriously injured.<br />
1. Attach one end of a jumper cable to the positive terminal<br />
of the discharged (dead) battery. This will have a large<br />
red “+” or “P” on the battery case, post, or clamp.<br />
2. Attach the other end of the same cable to the positive (+)<br />
terminal of the good (booster) battery.<br />
3. Attach the remaining jumper cable FIRST to the negative<br />
terminal (black “–” or “N”) of the good battery.<br />
4. Attach the other end of the negative cable to a bare<br />
metal part bolted to the engine block or clamp directly to<br />
the engine block if possible.<br />
IMPORTANT: Always connect positive (+) to positive (+)<br />
and negative (–) to negative (–).<br />
5. Start the engines:<br />
• Start the vehicle that has the good battery first. Let it<br />
run for a few minutes.<br />
• Then start the vehicle that has the discharged<br />
(dead) battery.<br />
