Now, if a door or the hatch/trunk lid is opened without
the key or the key fob transmitter, the alarm will go off.
Your horn will sound for two minutes, then it will go off
to save battery power. And, your vehicle won't start.
The theft
-deterrent system won't arm if you lock the
doors with a key, the manual door lock, or if you use the
power door lock after the doors are closed.
If your passenger stays in the vehicle when you leave
with the keys, have the passenger lock the vehicle after
the doors are closed. This way the alarm won't arm, and
your passenger won't set it off.
PASS-Key

Your vehicle is equipped
with the PASS
-Key
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key is a passive
theft
-deterrent system. It
works when you insert or
remove the key from
the ignition.PASS
-Key uses a resistor pellet in the ignition key that
matches a decoder in your vehicle.
When the PASS
-Key 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 shutdown period will start over
again. This discourages someone from randomly trying
different keys with different resistor pellets in an attempt
to make a match.
The key must be clean and dry before it's inserted in the
ignition or the engine may not start. If the SECURITY
light comes on, the key may be dirty or wet.
If this happens and the starter won't work, turn the
ignition off. Clean and dry the key, wait three minutes
and try again. If the starter still won't work, wait three
minutes and try the other ignition key. At this time, you
may also want to check the fuses (see ªFuses and Circuit
Breakersº 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.

2-25 Racing or Other Competitive Driving
See your Warranty Book before using your vehicle for
racing or other competitive driving.
NOTICE:
If you use your vehicle for racing or other
competitive driving, your engine may use more
oil than it would with normal use. Low oil levels
can damage the engine. Be sure to check the oil
level often during racing or other competitive
driving and keep the level at or near the upper
mark on the engine oil dipstick. You may need
to add oil. See ªAdding Oilº under ªEngineº in
the Index.
Engine Coolant Heater (If Equipped)
The engine coolant heater is located on the driver's side
of the engine under the manifold.
In very cold weather, 0
F (
-18
C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm
-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.

NOTICE:
Damage to your transmission caused by shifting
out of PARK (P) or NEUTRAL (N) with the
engine racing isn't covered by your warranty.
AUTOMATIC OVERDRIVE (
): This position is for
normal driving.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (
).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (
):

When driving on hilly, winding roads.

When going down a steep hill.SECOND (2): This position gives you more power but
lower fuel economy. You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
If you manually select SECOND (2) when you start the
vehicle, the transmission will drive (and stay) in second
gear. You may use this feature for reducing torque to the
rear wheels when you are trying to start your vehicle
from a stop on slippery road surfaces, or for preventing
the transmission from downshifting into FIRST (1) in
situations where a downshift would be undesirable.
FIRST (1): This position gives you even more power
(but lower fuel economy) than SECOND (2). You can
use it on very steep hills, or in deep snow or mud. If the
selector lever is put in FIRST (1), the transmission
won't shift into first gear until the vehicle is going
slowly enough.

yellowblue
2-32
This chart shows when to shift to the next higher gear
for the best fuel economy.
If your engine speed drops below 900 rpm, or if the
engine is not running smoothly, you should downshift to
the next lower gear. You may have to downshift two or
more gears to keep the engine running smoothly or for
good engine performance.
NOTICE:
When you are shifting gears, don't move the
gearshift lever around needlessly. This can
damage parts of the transmission and may
require costly repair. Shift directly into the next
appropriate gear.
One to Four Light (Manual Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to
deactivate this feature. This helps you get the best
possible fuel economy.
After shifting to FOURTH (4), you may downshift to a
lower gear if you prefer.

Convex Outside Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before
changing lanes.
Storage Compartments
Instrument Panel Cupholder
The cupholder is located on the center console in front of
the ashtray. To open it, place your thumb on the left side
of the lid and raise the right side with your index finger.
Center Console Storage
To use this storage area, pull up the lid on the driver's
side front edge of the console and swing it to the
passenger's side.
You can use the key to lock and unlock the console.
Don't leave the key in the lock, or it could be damaged
when the driver sits down.
The fuel fill door release button and accessory power
outlet are located inside the center console.

Instrument Panel Cluster
Your instrument panel cluster and Driver Information Center (DIC) are designed to let you know at a glance how the
vehicle is running. You'll know how fast you're going, about how much fuel you have left and many other things
you'll need to know to drive safely and economically. The instrument panel cluster indicator warning lights, gages
and DIC messages are explained on the following pages.

2-77 Speedometer and Odometer
Your speedometer lets you see your speed in either miles
per hour (mph) or kilometers per hour (km/h).
You may note that there are not two separate scales for
mph and km/h. When you press the E/M
(English/Metric) button on the Driver Information
Center (DIC), the cluster will calculate the proper speed
and move the needle to the correct position. Either the
MPH or the km/h telltale will illuminate, depending on
which measurement you choose.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
If it can't, then a new instrument cluster is replaced in
the vehicle and a label must be put on the driver's door
to show the old mileage reading when the new odometer
was installed. See your dealer if a new odometer must
be replaced in your vehicle.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Fuel will shut off at about 6200 rpm.
If you continue to drive your vehicle at the fuel shut off
rpm, you could damage your engine. Be sure to operate
your vehicle below the fuel shut off rpm or reduce your
rpm quickly when the fuel shuts off.
Warning Lights, Gages and Messages
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.

2-83 Malfunction Indicator Lamp
(Check Engine Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transmission,
exhaust or fuel system of your vehicle or the
replacement of the original tires with other than
those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the CHECK ENGINE light to
come on. Modifications to these systems could
lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.
