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 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” in the
Index). 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 PASS
-
Key II.

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 (see “Fuses and Circuit Breakers” in the Index).
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 light, located on the
instrument panel, will also be on.
Flash-to-Pass Feature
This feature lets you use your high
-
beam headlamps
to signal the driver in front of you that you want to pass.
It works even if your headlamps are off.
To use it, pull the turn signal lever toward you a little,
but not so far that you hear a click.
If your headlamps are off or on low beam, your
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 dash will come on.
Release the lever to return to normal operation.

Auxiliary Power Connection
(Power Drop)
Your vehicle is equipped
with an auxiliary
power connection.
It is located on the passenger’s side of the vehicle,
under the glove box, and is labeled with a wire function
and fuse rating. This feature provides power, ground
and accessory wires which can be accessed to add
aftermarket electrical equipment to your vehicle.
For information on accessing the connection and
electrical hookup, please refer to your service manual.
To order a service manual, see “Service Publications,
Ordering” in the Index.
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 anything that
exceeds the fuse rating.

Low Oil Pressure Warning 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:
D
The light will come on briefly when you turn on the
ignition to show you that is 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.)
D
Sometimes when the engine is idling at a stop, the
light may blink on and off. This is normal.
CAUTION:
Don’t keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches fire. You or others could be burned.
Check you 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.

To reset (calibrate) the system: turn the ignition switch
to RUN. Then press and hold the RESET button for
about five seconds. The red RESET button is located
inside 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. 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.
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
(105 km/h). When learning is complete, the system will
alert you after 2
-
8 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 mph (110 km/h).
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual wear,
rotate your tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels. See
“When It’s Time for New Tires” and “Wheel
Replacement” later in this section for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.

Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood electrical center. 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 Wipers
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
it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel 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.
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 in the 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 rating.
Instrument Panel Fuse Block
Some fuses are located
in a fuse block on the
passenger’s side of the
instrument panel. Pull off
the cover labeled FUSES to
expose the fuses.
