If something electrical in your
vehicle stops working, the first thing
youshouldcheckforisablownfuse.
Determine f rom the chart on pagesand , or the diagram on the
fuse box lid, which fuse or fuses
control that device. The diagram f or
theinteriordriver’ssidefuseboxis
on the kick panel below the f use box.
Check those f uses f irst, but check all
the f uses bef ore deciding that a
blown f use is the cause. Replace any
blown f uses, and check if the device
works.
Turn the ignition switch to LOCK
(0). Make sure the headlights and
all other accessories are off.
Remove the cover f rom the f use
box. 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
screwdriver.
Check the smaller f uses in the
under-hood f use boxes and all the
fuses in the interior fuse box by
pulling out each one with the f use
puller provided in the primary
under-hood f use box.

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 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 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.
Look f or a burned wire inside the
f use. If it is burned, replace it with
oneof thesparefusesof thesame
rating or lower. 6.

that has a higher rating greatly
increases the chances of damaging the
