The sensor on the negative terminal
monitors your vehicles battery
condition.
If there is a problem with the sensor,
you will see a‘‘CHECK BATTERY
SENSOR’’ message on the multi-
information display. Have the vehicle
checked by your dealer. Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a cloth
or paper towel. Coat the terminals
with grease to help prevent further
corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualified technician.
WARNING:
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle's
electrical system. Always disconnect
the negative (－ ) cable first, and
reconnect it last.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt
you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.
If the radio fuse is removed, the
audio system will disable itself. The
next time you turn on the radio you
will see ‘‘ENTER CODE ’’in the
frequency display. Use the preset
buttons to enter the digit code (see
page 305).

Diagnosing why the engine won't
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:●
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
faster than normal, but the engine
does not start up and run.
Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all. Check these things:
●
Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.
●
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
Jump Starting
on page 552.
●
Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the fuses. If the fuses
are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. See
Emergency Towing on page 566.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
connections (see page 541). You
can then try jump starting the
vehicle from a booster battery (see
page 552).
The Starter Operates Normally
In this case, the starter motor's speed
sounds normal, or even faster than
normal, when you turn the ignition
switch to the START (III) position,
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 instrument panel
to blink rapidly (see page 72).

If this indicator comes on
while driving, it means one
of the engine's emissions control
systems may have a problem. Even
though you may feel no difference in
your vehicle's performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damage.
If you have recently refueled your
vehicle, the indicator coming on
could be due to a loose or missing
fuel fill cap. Tighten the cap until it
clicks at least once. Tightening the
cap will not turn the indicator off
immediately; it can take several days
of normal driving. If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have your vehicle
checked by the dealer as soon as
possible.
If you keep driving with the malfunction
indicator lamp on, you can damage
your vehicle's emissions controls and
engine. Those repairs may not be
covered by your vehicle's warranties.
You will also see a
‘‘CHECK
EMISSION SYSTEM ’’message on
the multi-information display (see
page 86).
Readiness Code
Your vehicle has certain ‘‘readiness
codes ’’that are part of the on-board
diagnostics for the emissions systems. In
some states, part of the emissions testing
is to make sure these codes are set. If
they are not set, the test cannot be
completed.
If the battery in your vehicle has been
disconnected or gone dead, these codes
may be erased. It takes several days of
driving under various conditions to set
the codes again.
To check if they are set, turn the ignition
switch to the ON (II) position, without
starting the engine. The malfunction
indicator lamp will come on for 20
seconds. If it then goes off, the readiness
codes are set. If it blinks five times, the
readiness codes are not set. If possible,
do not take your vehicle for an emissions
test until the readiness codes are set.
Refer to Emissions Testing for more
information (see page 583).Malfunction Indicator Lamp

5. Look for a burned wire inside thefuse. If it is burned out, replace it
with one of the spare fuses of the
same rating or lower. If you cannot drive the vehicle
without fixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
from one of the other circuits. Make
sure you can do without that circuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown fuse with a
spare fuse that has a lower rating, it
might blow out again. This does not
indicate that anything is wrong.
Replace the fuse with one of the
correct rating as soon as you can.
Replacing a fuse with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a
replacement fuse with the proper rating
for the circuit, install one with a lower
rating.
6. 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
qualified technician.
If the radio fuse is removed, the
audio system will disable itself. The
next time you turn on the radio you
will see ‘‘ENTER CODE ’’in the
frequency display. Use the preset
buttons to enter the digit code (see
page 305).

Your vehicle has several identifying
numbers located in various places.
The vehicle identification number
(VIN) is the 17-digit number your
dealer uses to register your vehicle
for warranty purposes. It is also
necessary for licensing and insuring
your vehicle. The easiest place to
find the VIN is on a plate fastened to
the top of the dashboard. You can
see it by looking through the
windshield on the driver's side. It is
also on the certification label
attached to the driver's doorjamb,
and is stamped on the engine
compartment bulkhead. The VIN is
also provided in bar code on the
certification label.
