technician to have the 42-volt battery system
reconnected. See What Will You See After

Fuses and Circuit Breakers

The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers and fusible thermal links.
This greatly reduces the chance of fires caused by
electrical problems.
Be sure you replace a bad fuse with a new one of
the identical size and rating.
If you ever have a problem on the road and do not
have a spare fuse, you can borrow one that has the
same amperage. Just pick some feature of your
vehicle that you can get along without — like the
radio or cigarette lighter — and use its fuse, if it is
the correct amperage. Replace it as soon as
you can.
Your vehicle also has a special fuse in the battery
box for the 42-volt batteries. If this fuse has
failed and needs to be replaced, the vehicle will
be disabled and you will need to have your vehicle
repaired by your dealer. Do not attempt to
self-service this fuse.
