Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereisproba-
bly something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. (Seeon page .)
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the car from
a booster battery (see page ). In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.
Do you have f uel? Turn the
ignition switch to ON (II) for a
minute and watch the f uel gauge.
The low f uel level warning light
may not be working, so you were
not reminded to f ill the tank.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
Your car has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page ).
A key that is not properly coded
will cause the immobilizer system
indicator in the dash panel to blink
rapidly.
Are you using the proper starting
procedure? Ref er to
on page . If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See
on page .

All the electrical circuits in your car
have fuses to protect them from a
short circuit or overload. These
f uses are located in two f use boxes.The interior f use box is underneath
the steering column. To open it, turn
the knobs as shown.The under-hood f use box is located
in the back of the engine
compartment on the lef t side. To
open it, push the tabs as shown.

If something electrical in your car
stops working, the f irst thing you
should check f or is a blown f use.
Determine f rom the chart on pagesand , or the diagram on the
fuse box lid, which fuse or fuses
control that component. Check those
f uses f irst, but check all the f uses
bef ore deciding that a blown f use is
not the cause. Replace any blown
f uses and check the component’s
operation.
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 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 box by
pulling out each f use with the f use
puller provided in the interior f use
box.

Look f or a burned wire inside the
f use. If it is burned, replace it with
oneof thesparefusesof thesame
rating or lower.If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem in your car.
Leave the blown fuse in that
circuit and have your car checked
by a qualif ied mechanic.
If you cannot drive the car 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 sure
youcandowithoutthatcircuit
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.
