In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to the START (III)
position or on models with keyless
access system, press the engine
start/stop button to set START
Mode (see page ), but the engine
does not run.
Turn the ignition switch to the
START (III) position or on models
with keyless access system, press
the engine start/stop button to set
STARTMode(seepage ).If
the headlights do not dim, check
the condition of the fuses. If the
f uses are OK, there is probably
something wrong with the
electrical circuit for 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
discharged 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
).
Are you using a properly coded
key or keyless access remote (on
models with keyless access
system)? An improperly coded key
or keyless access remote will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ).65

If something electrical in your
vehicle stops working, the first thing
youshouldcheckforisablownfuse.
Determine f rom the chart on pages, and , or the diagram on
thefuseboxlidorthefuselabel,
which f use or f uses 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 if the device works. 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 at the wire inside.
Removing these f uses requires a
Phillips-head screwdriver.
Turn the ignition switch to the
LOCK (0) position.
Make sure the headlights and all
other accessories are of f .

Look f or a blown wire inside the
f use. If it is blown, replace it with
one of the spare f uses of the same
rating or lower.
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 one with the f use
pullerprovidedonthebackof the
under-hood f use box cover.
Also check the combined f use box in

If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem with your
vehicle. Leave the blown fuse in
that circuit, and have your vehicle
checked by a qualif ied technician.
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).
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 that anything is wrong.
Replace the f use with one of the
correct rating as soon as you can.
Your vehicle has spare fuses on the
back of the under-hood f use box
cover. 6.

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