Key

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 you accidentally use a key that has a damaged or
missing resistor pellet, the starter won’t work. The
SECURITY light will then come on. But you don’t have
to wait three minutes before trying another ignition key.
See your dealer or a locksmith who can service the
PASS
-
Key II to have a new key made.
If you’re ever driving and the SECURITY light comes
on, you will be able to restart your engine if you turn it
off. Your PASS
-
Key II system, however, is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by the PASS
-
Key II system.
If you lose or damage a PASS
-
Key II ignition key,
see your dealer or a locksmith who can service
PASS
-
Key II to have a new key made. Also,
see “Roadside Assistance” in the Index for
more information.

Turn Signal and Lane Change Indicator
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 is finished, the lever will return automatically.
An arrow on the instrument
panel cluster will flash in
the direction of the turn
or lane change.
To signal a lane change, just 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.
If the arrow flashes 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 (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.
2-52
To use the lighter, just push it in all the way and let go.
When it’s ready, it will pop back out by itself.
NOTICE:
Don’t hold a cigarette lighter in with your hand
while it is heating. If you do, it won’t be able to
back away from the heating element when it’s
ready. That can make it overheat, damaging the
lighter and the heating element.
Sun Visors
To block out glare, you can swing down the visors. You
can also move them from side to side. The visors also
have extenders that you can pull out for added coverage.
Visor Vanity Mirrors
Open the cover on the visor to expose the vanity mirror.
If your vehicle has the optional lighted vanity mirrors,
the lamps come on when you open the cover.
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.
2-53
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.

Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to
help your vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON light is on or not working properly.
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:
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.
6-44
To reset (calibrate) the system:
1.
Turn the ignition switch to RUN.
2.
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.
6-59
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.
