1. Put the tire on the ground at the rear of the vehicle,
with the valve stem pointed up and to the rear.
2. Pull the retainer through the wheel.
3. Put the socket end of the extension, on an angle,
through the hole in the rear bumper and into the
hoist shaft.
4. Raise the tire fully against the underside of the
vehicle. Continue turning the wheel wrench
clockwise until you hear two clicks or feel it skip
twice. This indicates that the tire is secure and the
cable is tight. The spare tire hoist cannot be
overtightened.5. Make sure the tire is stored securely. Push, pull
and then try to turn the tire. If the tire moves, use
the wheel wrench and socket end of the extension
to tighten the cable.
Return the jack, wheel wrench and wheel blocks
to the proper location in the vehicle. Roll up
the instruction label and return it to the slot in the
tool kit.

Fuses and 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 ®res
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.
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 Ð like the radio or
cigarette lighterÐ and use its fuse, if it is the correct
amperage. Replace it as soon as you can.
Engine Compartment Fuse Block
The fuse block is located under the hood in the engine
compartment on the driver's side of the vehicle. See
Engine Compartment Overview on page 5-12for more
information on location.
Remove the primary cover by pressing the two locking
tabs. Remove the secondary cover by snapping off
while lifting. To reinstall the fuse panel cover, reverse
the sequence.
