Taking Care of the Unexpected

Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
key to START (III):You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run.
When you turn the ignition switch to
START (III), you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Check these things: Check the transmission interlock.
The transmission must be in Park
orNeutralorthestarterwillnot
operate.
Turn the ignition switch to ON (II).
Turn on the headlights, and check
their brightness. If the headlights
are very dim or don’t light at all,
the battery is discharged. See
on page .
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereis
probably something wrong with
the electrical circuit f or the
ignition switch or starter motor.
You will need a qualif ied
technician to determine the
problem (see
on 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 vehicle
f rom 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. Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the dash panel to blink
rapidly(seepage ).

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.

NOTICE:BLOWNReplacing 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
replacement f use with the proper rating
f or the circuit, install one with a lower
rating.
