with
the
manual
door lock and
open the
door.
This should set
off
the alarm.
If
the alarm does
not
sound
when it should, but the
vehicle’s
lamps flash, check to see
if
the horn works.
The horn fuse
may
be
blown. To replace the fuse,
see
Fuses
and
Circuit
Breakers
on
page

Operation
Your vehicle is equipped
Ill
(Personalized Automotive
Security System)
theft-deterrent system.
Ill
is a passive
theft-deterrent system.
This means
you don’t have
to do anything different
to arm or disarm the
system. It works
when
you
insert or
remove
the
key
from the ignition.
Ill
system
senses that someone
is using the wrong key, it shuts down the vehicle’s
starter and fuel systems. The starter will not work
and
fuel will stop being delivered to
the engine. Anyone
using a trial-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
When trying to start
the vehicle,
if
the engine
does
not
start and the
SECURITY
light comes
on,
the
key
may
have
a
damaged
transponder.
Turn
the ignition
off
and try again.
If the engine still does not start,
and
the
key
appears
to
be
undamaged, 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
engine still
does not start with the
other key, your
vehicle
needs
service. If your vehicle does
start,
the
first
key may
be
faulty. See your dealer
who
can
service
the
Ill
to have a new key made.
It is possible for
the
Ill
decoder to learn
the transponder value of a
new
or
replacement
key.
Up to
10
additional keys may
be
programmed
for
the vehicle. This procedure is
for
programming
additional
keys only.
2-20
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
the
fuse.
See
Fuses
and
Circuit
Breakers
on
page
5-90.
Turn

Chime
If
your turn signal is left on
for
more than
0.8
miles
(1

km),
a
chime will sound at each flash of the turn
signal. To turn
off
the chime, move the turn signal lever
to
the
off
position.
Headlamp
High/Low-Beam
Changer
To
change the headlamps from low beam to high beam
or high beam
to
low beam, pull the turn signal lever
toward you
and release it.
When the high beams are
on, this light located on
the
instrument panel cluster
will also be on.
If
your vehicle is equipped with the Head-Up
Display
(HUD),
this symbol will also
appear in the display
area to
indicate the high beams
are
on.
See
Head-Up
Display
(HUD)
on
page

for
more information.
Flash-To-Pass
This feature lets you
use
the
high-beam
headlamps to
signal the driver in front
of
you
that
you
want to pass.
It works
even
if
your headlamps are
off.
Pull the turn signal lever toward you
briefly to
flash-to-pass.
If the headlamps are
off
or
on
low
beam,
the
high-beam
headlamps will turn
on.
They’ll
stay
on as long as
you hold the lever toward you
and
the
high-beam
indicator on the instrument panel cluster will come
on.

Accessory
Power
Outlets
The
accessory
power
outlets can be used to plug in
electrical
equipment
such
as
a cellular telephone or
CB
radio.
Your
vehicle
may
have
up to three power outlets
depending
on
the
type of front seat
you
have.

may
have
a small cap that must be pulled
down to access
the
accessorypower outlet.
If
it
does,
when not using
the
outlet be sure to cover it with
the
protective
cap.
The accessory power outlets will
only operate when the
ignition key is
in

and for
10
minutes after turning
the ignition
off.
I f
you would like the outlets to operate
regardless
of
ignition position, and for extended periods
of
time, see “Engine
Compartment Fuse Block” under
Fuses and Circuit Breakers
on
page
5-90
or contact
your dealer.
Notice:
When using an accessory power outlet,
maximum electrical load
must
not exceed
15
amps.
Always turn
off
any electrical equipment when
not in
use. Leaving electrical equipment on for
extended
periodswill drain
your
battery.
Certain electrical accessories may not be compatible to
the accessory power outlets and could result
in
blown
vehicle or adapter fuses.
If
you experience a problem
see your dealer for additional information on the
accessory power outlets.
Notice:
Adding some
electrical equipment
to
your
vehicle can damage it or keep other things from
working as
they should. This wouldn’t be
covered
by
your
warranty. Check with
your
dealer before
adding electrical equipment, and
never
use
anytning
that exceeds the amperage rating.

When adding electrical equipment, be sure to follow
the proper installation instructions included with
the equipment.
Notice:
Power outlets
are
designed
for
accessory
plugs
only. Do not
hang
any
type
of
accessory
or
accessory
bracket
from
the

Power
Windows and Other
Power
Options
Circuit breakers in the rear
fuse block 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
and
circuit
breakers. 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.
You
will find a fuse puller clipped in
both of the
fuse
blocks.
Snap the wide end of the fuse
puller
at
the
side
indentations and pull the
fuse
out.
The MaxiFuses are located in two fuse
blocks,
one
located in the engine compartment
on
the
passenger’s
side
and the other under
the
rear
seat on the
driver’s
side.
If
a MaxiFuse should
blow,
have
your
vehicle
serviced by
your
dealer
immediately.
