1. Remove the protective cap from the booster
block terminal located in the R.H. side
engine compartment;
2. Connect one end of the red jumper cable to
the positive (+) post of the booster power

7. Disconnect the jumper cables in reverse
order given in steps 2 through 5;
8. Install protective cap on the booster block
terminal.
NOTE
Jumper cables must be rated at 500 cranking
amperes. If jumper cable length is 20 feet (6
m) or less, use 2/0 (AWG) gauge wires. If
cable length is between 20 to 30 feet (6 to 9
m), use 3/0 (AWG) gauge wires.
