JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make
sure the vehicles are not touching. Turn off all unnecessary
lights and accessories.2. If required, remove all the vent plugs from the booster
battery. Lay a cloth over the open vents on the booster
battery. (This helps reduce the explosion hazard, personal
injuries and burns.)
If the booster battery is an extended maintenance interval
battery, it is not necessary to remove the vent plugs.
3. If the engine in the vehicle with the booster battery is not
running, start it and let it run for about 5 minutes. During jump
starting, run the engine at about 2000 rpm with the
accelerator pedal lightly depressed.
4. Locate positive (+) and negative (±) terminals of each
battery. Connect the jumper cables in the exact order (

 ) shown in the illustration.

Connect a positive (red) jumper cable clamp to the
positive (+) terminal of the discharged battery.
Connect the clamp at the other end of the positive (red)
cable to the positive (+) terminal of the booster battery.
Connect a negative (black) cable clamp to the negative
(±) terminal of the booster battery.
Connect the clamp at the other end of the negative
(black) cable to a solid, stationary, unpainted metallic
point (e.g. water inlet housing filler plug) away from the
battery. Do not connect it to or near any part that moves
when the engine is cranked.
