PREVENTIVE MAINTENANCE
WARNING! To avoid death, serious personal
injury and damage to the vehicle, heed all
warnings and instructions of the jumper cable
manufacturer.
• The jumper cables must be long enough so
that the vehicles do not touch.
If either battery has vent caps, remove them and check
the fluid level. If it is OK, replace the caps before going
further. If the level is low, add distilled water and replace
the caps before proceeding. If no water is available,
remove the caps and cover the filler openings with a cloth.
After jump starting the vehicle, dispose of the cloth.
WARNING! If you do not cover the filler openings
on the battery, electrolyte could boil out
of the openings and cause death, injury or
damage the vehicle. Replace caps securely if
the battery has the full level of electrolyte. If
the electrolyte is low and no water is available,
cover with a cloth.
Preparing the vehicles:
1. Position the two vehicles together, but do not let them
to touch.
