Jump-Starting Engine

If you encounter a situation in which it is necessary to jump-start an engine,
use the following procedures.
WARNING
Batteries which are to be linked together must be of the same voltage (12 to
12, 24 to 24). Take care to observe proper polarity when connecting batteries.
Batteries produce explosive gases. Keep sparks, flames, cigarettes, etc., away
from batteries at all times. Protect your eyes by wearing safety goggles. Be
sure vehicles are NOT touching each other.
CAUTION
To avoid damaging any electronic controllers when jump-starting a V-MAC vehicle,
always turn the ignition switch OFF before connecting the batteries.
1. Connect the positive (+) cable to positive (+) post of discharged battery or
to the positive post of the remote jump-start connector (if equipped).
2. Connect the other end of the same cable to the positive (+) post of the
booster battery.
3. Connect the second cable, negative (-) side, to the other post of the booster
battery.
4. Make the final connection to the negative (-) battery terminal or the remote
jump-start connector (if equipped) of the stalled vehicle, and stand back.
