Look f or a burned wire inside the
f use. If it is burned, replace it with
one of the spare f uses of the same
rating or lower.
Check each of the large f uses in
the primary under-hood f use box
by looking through the top at the
wire inside. Removing these f uses
requires a Phillips-head screw-
driver. Check the smaller f uses in the
under-hood f use box and all the
fuses in the interior fuse boxes by
pulling out each f use with the f use
puller provided in the primary
under-hood f use box.5.

If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem in your vehicle.
Leave the blown fuse in that
circuit and have your vehicle
checked by a qualif ied mechanic.If the radio f use is removed, the
audio system will disable itself . The
nexttimeyouturnontheradioyou
will see ‘‘ ’’ in the f requency
display. Use the Preset buttons to
enter the f ive-digit code (see page
).
If you cannot drive the vehicle
without f ixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
f rom one of the other circuits. Make
sureyoucandowithoutthatcircuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown f use with a
spare f use that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
f use with one of the correct rating as
soon as you can.

Replacing a f use with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a replace-
ment f use with the proper rating f or the
circuit, install one with a lower rating.

If your vehicle needs to be towed,
call a prof essional towing service or,
if youbelongtoone,anorganization
that provides roadside assistance.
Never tow your vehicle behind
another vehicle with just a rope or
chain. It is very dangerous.
There are three popular types of
prof essional towing equipment.
The operator
loads your vehicle on the back of a
truck. Any other
method of towing will damage the
drive system. When you contact the
towing agency, inf orm them that a
f lat-bed is required. The tow
truck uses two pivoting arms that go
under the tires (f ront or rear) and lif t
them of f the ground. The other two
tires remain on the ground. Refer to
on page
for non-emergency towing
inf ormation.
The tow
truck uses metal cables with hooks
on the ends. These hooks go around
parts of the f rame or suspension and
cables lif t that end of the vehicle of f
the ground. Your vehicle’s
suspension and body can be
seriously damaged. 283Flat -bed Equipment
