Content Theft-Deterrent
(If Equipped)
If your vehicle has’this option, it has a theft-deterrent
alarm system.
A red light located on top of your instrument panel (near
the center
of the vehicle, next to the windshield) will
flash slowly when the system is armed.
While armed, the doors will not unlock with the power
lock switch. The
alarm will go off if someone damages
the vehicle, tampers with the trunk lock, enters the
vehicle (without using the remote keyless
entry
transmitter or key to unlock the doors), or turns the
ignition on. Your
horn will sound and your headlamps
will
flash for up to two minutes. The system will also
cut off the fuel supply, preventing the vehicle from
being driven.
Arming with the Power Lock Switch
Your alarm system will arm when you use either the
power lock switch to lock the doors while any door is
open and the key is removed from the ignition (if you
would like to
turn off the power door lock switch
arming, see “Locks and Lighting Choices” in the Index).
The security light flashes quickly to let you know when
the system is ready
to arm with the power door switches.
The security light will stop flashing
and stay on when
you press the rear of the power lock switch, to let you
know the system is arming. After all doors are closed
and locked, the security light will begin flashing at a
very slow rate to let you know the system is armed.

Engine Coolant Heater (If Equipped)
6
In very cold weather, 0 OF (- 18 O 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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located below the
air cleaner near the coolant
reservoir bottle.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
I
A CAUTION:
-
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt
AC outlet. If the cord won't reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.
4. Before starting the engine, be sure to unplug and store
the cord as it was before to keep it away from moving
engine parts. If you don't, it could be damaged.

AUTOMATIC OVERDRIVE (D): This position is for
normal driving.
If your vehicle has overdrive, AUTOMATIC
OVERDRIVE
(D) is the overdrive position. If you need
more power for passing, and you’re:
Going less than 35 mph (55 km/h), push your
Going about 35 mph (55 km/h) or more, push the
accelerator pedal about halfway down.
accelerator pedal
all the way down.
You’ll shift down to the next gear
and have
more power.
NOTICE:
If your vehicle seems to start up rather slowly, or
if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor.
If you drive very far that way, your
vehicle can be damaged.
So, if this happens, have
your vehicle serviced right away. Until then, you
can use
SECOND (2) when you are driving less
than
35 mph (55 km/h) and AUTOMATIC
OVERDRIVE
(D) for higher speeds. THIRD
(3): This
position is also used for normal
driving, but it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE
(D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
0 When going down a steep hill.
2-23

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.
NOTICE:
.
Don’t drive in SECOND (2) for more than
25 miles (40 km) at speeds over 55 mph
(88 km/h), or you can damage your transaxle.
Use AUTOMATIC OVERDRIVE (D) or
THIRD (3) as much as possible.
Don’t shift into
SECOND (2) unless you are going
slower than
65 mph (105 km/h), or you can
damage your engine. 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 shift
lever is put in FIRST (1)’ the transaxle won’t shift into
first gear until the vehicle is going slowly enough.
NOTICE:
If your front wheels can’t rotate, don’t try to
drive. This might happen
if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transaxle.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into
PARK (P)
to hold your vehicle in position on a hill.
2-24

Performance Shifting (If Equipped)
1 Press the performance shift
button, located
on the side
of the console shift knob,
to allow the transaxle to
shift
at higher engine
speeds, increasing
acceleration performance.
If you have a vehicle with the
3800 Supercharged
engine option, the
“PERF SHIFT” light in the
instrument panel cluster will come on.
Downshifts will occur at a lower percentage of
accelerator use while you’re
in the performance
shift mode.
Press the button again to return to normal shifting. The
transaxle
will then shift at lower engine speeds,
increasing fuel economy.
Parking Brake
To set the parking brake,
hold the regular brake pedal
down with your right foot.
Push down the parking
brake pedal with
your
left foot.
To release the parking brake, hold the regular brake
pedal down with your right foot and push the parking
brake pedal with your left foot. When you lift your left
foot, the parking brake pedal will follow it to the
released position.

Instrument Panel Cluster
/
APPLY BRAKE TO Y((FT FROM PARK
United States Version Shown, Others Similar
Your instrument cluster is designed to let you know at a glance how your vehicle is running. You’ll know how fast
you’re going, about how much fuel
is in your tank and many other things you need to drive safely and economically.
2-62

The low traction light also comes on briefly when you
turn the ignition key to RUN. If the light doesn’t come
on then, have
it fixed so it will be there to tell you when
the anti-lock brake system, Traction Control System or Enhanced Traction System is active.
Malfunction Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENGINE SOON
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD
I1 (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
SERVICE ENGINE SOON 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.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0
a
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center
diagnosis and
service may be required.
2-69

If the Light Is Flashing If the Light Is On Steady
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
0 Avoiding hard accelerations.
Avoiding steep uphill grades.
0 If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light
Is On Steady” following.
If the light continues to flash, when
it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key
off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see “If
the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your dealer or qualified service center for service.
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put
fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system
can determine if the fuel
cap has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should
turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not
run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect
this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel?
2-70

If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel
quality will cause your
engine not to
run as efficiently as designed. You may
notice
this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to
turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to
turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic
tools to fix any mechanical or electrical
problems that may have developed.
Oil Warning Light
If you have a problem with
your oil pressure, 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 two other situations:
0
0
When the ignition is on but the engine is not running,
the light will come on
as a test to show you it is
working, but the light
will go out when you turn the
ignition to START.
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.
If you make
a hard stop, the light may come on for a
moment. This is normal.
