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.
PASS-Key®II
Your vehicle is equipped
with the PASS-Key®II
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
®II is a passive
theft-deterrent system.
It works when you insert or
remove the key from the
ignition.
PASS-Key
®II uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.When the PASS-Key
®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 warning
light on the instrument panel isflashing, 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. SeeFuses and Circuit
Breakers on page 5-87. If the starter won’t work with the
other key, your vehicle needs service. If your vehicle
does start, thefirst ignition key may be faulty. See your
dealer or a locksmith who can service the PASS-Key
®II.

Turn and Lane-Change Signals
The turn signal has the following positions: two upward
(for right) and two downward (for left). 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 isfinished, the lever will return
automatically.
An arrow on the instrument
panel cluster willflash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts toflash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
If the arrowflashes faster than normal as you signal a
turn or a lane change, 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 then check the
fuse. SeeFuses and Circuit Breakers on page 5-87.
A chime will sound if you leave your turn signal on for
more than 3/4 mile (1.2 km).
Headlamp High/Low-Beam Changer
To change your headlamps from low beams to
high beams, or high to low, pull the multifunction lever
all the way toward you. Then release it.
When the high beams are
on, this indicator light
located on the instrument
panel cluster will also
be on.

Tire Pressure Monitor System
If your vehicle has the tire inflation monitor system, it
can alert you to a large change in the pressure of
one tire. The system“learns”the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 45 and 90 minutes
of driving to learn the tire pressures. This time may
be longer depending on your individual driving habits.
Learning need not be accumulated during a single
trip. Once learned, the system will remember the tire
pressures until the system is recalibrated.
After the system has learned tire pressures with properly
inflated tires, the LOW TIRE light will come on if the
pressure in one tire becomes 12 psi (83 kPa) lower than
the other three tires. The tire inflation monitor system
won’t alert you if the pressure in more than one tire is low,
if the system is not properly calibrated, or if the vehicle is
moving faster than 70 mph (110 km/h).
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.
SeeTires on page 5-56.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 isflat, seeIf a Tire Goes Flat on page 5-66.)
Also check the tire pressure in all four tires as soon as
you can. SeeInflation—Tire Pressure on page 5-57.
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 thefirst button in the top row of
the fuse block.

Service Parts Identication Label
You’llfind this label on the inside of the trunk lid. It’s very
helpful if you ever need to order parts. On this label is:
•your VIN,
•the model designation,
•paint information and
•a list of all production options and special equipment.
Be sure that this label is not removed from the
vehicle.
Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your vehicle
unless you check with your dealerrst. Some
electrical equipment can damage your vehicle and
the damage wouldn’t be covered by your warranty.
Some add-on electrical equipment can keep other
components from working as they should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-54.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood fuse block. An electrical overload will
cause the lamps to go on and off, or in some cases to
remain off. If this happens, have your headlamp
system checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a 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, have
itfixed.
Power Windows and Other Power
Options
Circuit breakers in the instrument panel 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 isfixed.

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 offires 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.
Instrument Panel Fuse Block
Some fuses are located in
a fuse block on the
passenger’s side of the
vehicle. Pull off the cover
labeled FUSES to
expose the fuses.
