Fuse Id Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires caused
by electrical problems.
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.
Engine Con tment Fuse Bloc
-;
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. 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.
There are three fuse blocks in your vehicle: the engine
compartment fuse block, the MaxiFuse relay center and
the rear compartment fuse block.
The fuse block is located next to the air filter on the
driver's side of the engine. Lift the cover to gain access.
