For your safety, we strongl y recommend that you do not travel with a portable fuel
cially in cras h.
If , under exceptional circum stances, you must transport a portable fuel co ntain er,
pl ease observe the foUowing:
- Never
fill a portable fuel container while
it is anywhere in or on the ve hicl e (for ampl e, in the lu ggage compartment, or on the trunk). electricity can build up while filling and can ig nite fuel vapors

- Always pl

-Alway s keep the filler nozz le co mplet ely
in side the portab le container b efo re and during fillin g.
- If filling a
portable container made of
metal , the filler nozzle must a lway s be in
contact with the container. This will help prevent static e lec tricity from disc ha rgin g and ca use a fire.
