the right-hand and left-hand sides of the vehi-
cle. If one of the fuel tanks is defective, it can
be disabled and the other fuel tank can be
used instead.

Refuelling
i
When refuelling the vehicle for the first
time, make sure a fuel tank on one side is
completely filled. In this manner, the expan-
sion line is depressurised and the correct
function of the expansion line is ensured. If
the expansion line or the drain plug has
been opened, e.g. for maintenance or repair
work, repeat this procedure. The vehicle
may otherwise be refuelled simultaneously
or alternately at the next refuelling.
