correct fuse.
Spare fuses are provided, however if you ever have a problem on the road
and don’t have a spare fuse, you can “borrow” one of the correct value. 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 of the value you need.
Replace it as soon
as you can. See “Fuses and Circuit Breakers” in this
section.
To reinstall the fuse panel cover, push in and turn the fastener clockwise.
