Caution
Do not connect the negative terminal
when finally connecting to the
vehicle you want to charge.
In final connection, attach the clip to
the steel frame bolted to the engine
block.
The final connection point should be
as far away from the battery as
possible.
If you connect the jumper cable to
the negative terminal on the dead
battery, it can cause arcs or even
battery explosion.
Serious personal injury or vehicle
damage can result.
4. Turn off the electrical devices on
the vehicle as possible (e.g. lights,
blower, audio system), start and run
the discharged vehicle for 20

battery.
5. During jump starting, the engine on
the vehicle providing the jump
starting can be allowed to run.
Caution
Attempts to start the engine of the
vehicle with the discharged battery
should be made at intervals of about
one minute and should not last longer
than 15 seconds each.
After the vehicle with discharged
battery starts:
1. Take care to disconnect the
grounding terminal (-).
Disconnect from the vehicle with
discharged battery first. Keep the
engine running on the vehicle with
discharged battery.
