Look at the silver-colored band
inside the fuse. If the band is broken
or melted, replace the fuse. 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 don't 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.Engine Compartment
Fuse Block
The Engine Compartment Fuse
Block is located in the engine
compartment, on the driver side of
the vehicle. Lift the cover for access
to the fuse/relay block.
If the vehicle is a hybrid, see
the hybrid supplement for more
information. Notice:
Spilling liquid on any
electrical component on the
vehicle may damage it. Always
keep the covers on any electrical
component.
To remove fuses, hold the end of
the fuse between your thumb and
index finger and pull straight out.
