{CAUTION:
You can lose control of the vehicle if you try to

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
The 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 the ignition
key is inserted or
removed from the ignition.
PASS-Key
®II uses a resistor pellet in the ignition key
that matches a decoder in the vehicle.When the PASS-Key
®II system senses that the wrong
key has been inserted into the ignition, it shuts down
the vehicle’s starter and fuel systems. The starter will not
work and fuel will not go to the engine for about
three minutes. If someone tries to start the vehicle again
with the wrong key, or uses another incorrect key
during this time, the vehicle will not start. This
discourages someone from randomly trying keys with
different resistor pellets in an attempt to make a match.
The ignition key must be clean and dry before it is
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 is ashing, 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 vehicle still does not start, the ignition
key may be faulty. Wait about three more minutes and
try a spare ignition key. At this time, you may also
want to check the fuse. SeeFuses and Circuit Breakers
on page 5-91for information on fuse location. If the
starter will not work with the spare key, the vehicle
needs service. See your dealer or a locksmith who can
service the PASS-Key
®II.

Turn Signal/Multifunction Lever
The multifunction lever located on the left side of the
steering column includes the following:
Turn and Lane-Change Signals
Headlamp High/Low-Beam Changer
Flash-to-Pass
Windshield Wipers
Windshield Washer
Cruise Control
Turn and Lane-Change Signals
To signal a turn, move the turn signal/multifunction lever
up or down. The lever returns to its original position
when the turn is completed.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
To signal a lane change, raise or lower the turn signal/
multifunction lever until the arrow starts to ash. Hold it
there until the lane change is completed. The lever will
return to its original position when released.
Arrows that ash rapidly when signaling for a turn or
lane change, or that fail to work, may indicate a
burned-out signal bulb or fuse. Other drivers will not see
the signal. SeeFront Turn Signal and Parking Lamps
on page 5-48andTaillamps, Turn Signal, and
Stoplamps on page 5-50for turn signal bulb replacement
procedures. Also seeFuses and Circuit Breakers on
page 5-91for location of fuses.
A chime will sound if the turn signal is left on for more
than 3/4 mile (1.2 km).

Ashtrays and Cigarette Lighter
The center front ashtray is located below the instrument
panel comfort controls.
To remove the ashtray, open the storage door.
Then open the ashtray lid, lift up and pull it out.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
Push the lighter to use it. When the heating element is
hot, the lighter will pop back out by itself.
Notice:If you put papers or other ammable items
in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
your vehicle. Never put ammable items in
the ashtray.
Climate Controls
Dual Climate Control System
Your vehicle may have this climate control system.
The heating, cooling, and ventilation for the vehicle can
be controlled with it.
Manual Operation
To change the current mode, select one of the following
settings on the right knob.
MAX (Maximum Air-Conditioning):This mode
recirculates much of the air inside the vehicle and sends it
through the instrument panel outlets. The air-conditioning
compressor will run automatically in this setting unless
the outside temperature is below 40°F (4°C).

xed right away.
Sometimes when the engine is idling at a stop,
the light may blink on and off. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.

Doing Your Own Service Work
If you want to do some of your own service work, you
will want to use the proper service manual. It tells
you much more about how to service your vehicle than
this manual can. To order the proper service manual,
seeService Publications Ordering Information on
page 7-11.
Your vehicle may have an airbag system. If it does, see
Servicing Your Airbag-Equipped Vehicle on page 1-58
before attempting to do your own service work.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. SeeMaintenance Record on page 6-16.{CAUTION:
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. English and metric
fasteners can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
