Theft-Deterrent
Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number
of theft-deterrent
features, we
know that nothing we put on
it
can
make it
impossible to steal. However, there are ways
you
can help.
I1
Your vehicle is equipped
II
(Personalized Automotive
Security System)
theft-deterrent system.
II
is a passive
theft-deterrent system.
It works
when
you insert or
remove the key from the
ignition.
II
uses
a
resistor pellet in the ignition key
that matches
a
decoder in your
vehicle.
II
system
senses
that
someone is
using the wrong key, it shuts
down the vehicle’s
starter and fuel systems.
For about three minutes,
the
starter won’t
work and fuel won’t
go to the
engine.
If
someone tries to start
your
vehicle
again or
uses
another key during this time, the vehicle will not
start.
This discourages someone from randomly trying different
keys
with different resistor pellets in an
attempt to
make a match.
The ignition key must
be clean and
dry before it’s inserted
in the ignition or the engine may not start.
If
the
engine
does not start and the SECURITY light is flashing,
the
key
may
be dirty or
wet. Turn the ignition
off.
Clean
and dry the key. Wait about three minutes
and
try
again.
If
the starter still won’t
work,
and
the
key
appears to be clean and dry, wait
about three minutes
and try another ignition key. At this time,
you
may
also want to check the
fuse.
See
Fuses and Circuit
Breakers
on
page
5-90.
If
the starter won’t
work
with
the
other key,
your vehicle needs
service.
If
your
vehicle
does
start, the first ignition key may
be
faulty.
See
your
dealer or a locksmith who
can service the

two
downward (for left). These positions
allow you to signal a turn or a lane change.
To
signal a turn,
movethe lever all the way
up or down.
When the turn is finished, the lever will return
automatically.
An arrow on the instrument
Dane1 cluster will flash in
I
ihe direction of the

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 then check the
fuse.

Your
vehicle
will
not
pass this inspection
if
the
OBD
(on-board
diagnostic)
system determines that critical
emission
control
systems have not been completely
diagnosed
by the system. The vehicle would be
considered
not
ready
for
inspection. This can happen
if
you
have
recently replaced your battery or
if
your
battery has run
down. The diagnostic system is
designed
to
evaluate critical emission control systems
during
normal
driving. This may take several days
of routine
driving.
If
you have done this and your vehicle
still does
not
pass the inspection for lack of
OBD
system
readiness,
see
your dealer or qualified service
center
to
prepare the vehicle for inspection.
Oil
Pressure
Light
If
you have a problem with
your oil, this light may stay
on after
you
start
your
engine,
or
come
on
when
you are driving.
This
indicates
that oil is
not going through your engine
quickly
enough to keep
it
lubricated. The
engine
could
be
low on oil or could have some
other oil
problem.
Have
it
fixed
right
away.
The oil light could also come on in the following
situations:
The light
will come on briefly when you turn on the
ignition to show you that
it
is working properly.
If
it
doesn’t come on with the ignition on, you may
have a problem with the fuse
or bulb. Have it fixed
right
away.
Sometimes
when the engine is idling at a
stop, the
light may blink on and
off.
This is normal.
Don’t keep d
ing
if
the
o
yessure
is
low.
If
you do,
your engine can become
so
hot that it
catches fire.
You
or
others could be burned.
Check your
oil as soon
as
possible and have
your
vehicle
serviced.
Notice:
Damage to your engine from
neglected oil
problems can be costly and
is
not covered by
your
warranty.

The tire inflation monitor system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The
system
can alert you about a
low
tire
-
but it doesn’t replace normal tire maintenance. See
Tires on
page
5-58.
When the LOW
TIRE light comes
on,
you should stop
as soon as you can and
check all your tires for
damage.
(If
a tire is flat,
see
If a Tire Goes
Flat
on page
5-67.)
Also
check
the tire pressure in all four tires as soon as
you can. See
lnflation
--
Tire Pressure
on
page
5-58.
The
LOW
TIRE light will also be displayed (while
the ignition is on) until you
reset (calibrate) the system.
Don’t reset the tire inflation monitor system without
first correcting the cause of the problem
and checking
and adjusting the pressure in all four tires.
If
you
reset the system
when the tire pressures are incorrect,
the system
will not work properly and
may
not alert
you
when a tire is low.
Any time you adjust a tire’s pressure, rotate your tires,
or
have
one
or
more
tires repaired or replaced, you’ll
need to reset (calibrate) the tire inflation monitor system.
You’ll also need to reset the system
whenever
you
buy
new tires and
whenever the vehicle’s battery has
been disconnected.
To
reset (calibrate) the
system:
1.
Turn the ignition to RUN.
2.
Locate the red RESET button inside of your
instrument panel fuse block.
The fuse block is located
under
the
cover labeled
FUSES,
which is at the
end of the
instrument
panel
on the passenger’s side of the
vehicle.
The
RESET button is the
first button in the
top
row
of
the fuse block.
seconds.
The
LOW
TIRE
light
will
come
on
and
flash three
times. Then it will go off. If the light doesn’t go
off,
see your dealer
for
service.
3.
Press and hold the
RESET button for
about
five
The
system
completes
the calibration process
during
driving.
The
system normally takes
15
to
20
minutes of driving
in each of three speed
ranges
to
”learn” tire pressures.
The
speed ranges are
15
to
40 mph
(25
to
65
km/h),
40
to
65 mph (65
to
105
km/h)
and
above
65
mph
(I05
km/h). When
learning is complete,
the
system
will
alert you after two
to
eight minutes
if
a tire
is
12
psi
(83
kPa) different from
the
other three tires.
Detection
thresholds may
be
higher
and detection times may
be longer on rough roads, curves and
at high speeds.
The
system is not
capable of detection at
speeds
greater
than
70

If
this
happens,
have your headlamp
system

Fuses
and
Circuit
Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and in the fuse
block wiring itself. 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
