Your vehicle is equipped with the [email protected]
theft-deterrent system.
is a passive theft-deterrent system.
[email protected] enables fuel
if
the ignition lock cylinder is
turned with a valid key.
If
a correct key is not used
or
the ignition lock cylinder
is
tampered with, the fuel
system is disabled and the vehicle will not start.
During normal operation, the security light will turn
off
approximately five seconds after
the key is turned
to
RUN.
If the engine stalls and the security light flashes, wait
about
10
minutes until the light stops flashing before
trying
to
restart the engine. Remember to
release
the key from START as soon
as
the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the security light comes on,
you will be able to restart the engine
if
you turn the
engine
off.
However, your
not working properly and must be serviced by your
dealer. Your vehicle is not protected by [email protected]
at this time. You may also want to check the fuse.

Turn and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn is finished, the lever will return
automatically.
To
signal a lane change, raise or lower the lever until
the arrow starts
to
flash. Hold it there until you complete
your lane change. The lever will return by itself when
you release it.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
As you signal a turn or a lane change,
if
the arrows flash
more quickly than normal, a signal bulb may be burned
out and other drivers won’t
see
your
turn signal.
If
a bulb is burned out, replace it to help avoid an
accident.
If
the arrows don’t
go
on
at all when you signal
a turn, check for burned-out bulbs and a blown fuse.
See
Fuses and Circuit Breakers
on page
5-102.

So
be sure to keep your
rear bumper free of mud, dirt,
snow, ice and slush or materials such as paint or

the display continues
to
flash red, see your
dealer.
For cleaning instructions, see
Cleaning the

As
always, drivers should use care when backing up a
vehicle.
Always
look behind you, being sure to check
for
other vehicles, obstructions and blind spots.

Windshield Wiper
Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due
to
heavy snow, etc., the wiper
will
stop until the motor
cools.
If
the overload
is
caused by some electrical
problem and not snow, etc., be sure to get
it
fixed.
Power
Windows and Other
Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load
is
too
heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.

Fuses
and
Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse.
If
the
band
is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and don’t have
a spare fuse,
you can borrow one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without
-
like the radio or
cigarette lighter
-
and use its fuse,
if
it is the correct
amperage. Replace it as soon as you can.
Instrument Panel
Fuse
Block
The fuse
block
access
door is on
the
driver‘s
side
edge of the
instrument
panel. Pull
off
the
cover
to
access the
fuse block.
You can remove
fuses
with a fuse
extractor
which is
mounted
to
the fuse block access door.
To
remove
fuses
if
you don’t have a fuse extractor, hold the end of the
fuse between your
thumb and index
finger
and pull
straight out.
You
may
have spare fuses located behind the
fuse
block access door. These can be used
to
replace a bad
fuse. However, make sure it is of the
correct
amperage.
