must transport a portable fuel container,
please observe the following:
- Never fi ll a po rtable fue l container
while it is anywhe re in or on the vehicle
(for examp le, in the luggage compar t­

on the gro und before filling.
- Always keep the fi ller nozzle comp lete­
ly inside the po rtable conta iner before
and during filling.
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. Th is w ill
he lp prevent static electricity from dis­
charging and cause a fi re .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fue l vapors are
h ighly f lammable .
- Always observe local and state/provin­
cial laws regard ing the use, storage
and tra nsporta tion of fuel co ntainers .
- Make certai n the fuel container meets
industry standards (ANSI/ ASTM

be able to detect the battery 's state of
charge. Always connect the negative
ground cab le to the negative ground post
of the battery manager control unit.
