Electrical System
Fuses and Circuit Breakers
The wiring circuits in the 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 the 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.
The vehicle also has a special fuse in the battery box
for the 300-volt batteries. If this fuse has failed and
needs to be replaced, the vehicle will be disabled and
you will need to have the vehicle repaired by your
dealer/retailer. Do not attempt to self-service this fuse.

more information on its location. For more information on
the main underhood fuse block, see “Underhood Fuse
