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.
Passlock®
Your vehicle has the Passlock®theft-deterrent system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If a correct key is not used or the
ignition lock cylinder is tampered with, the fuel system
is disabled and the vehicle will not start.
During normal operation, the THEFT SYSTEM light will
turn off approximately five seconds after the ignition
key is turned to ON and the engine is started.
After attempting to start the engine, if the THEFT
SYSTEM light flashes or stays on, wait ten minutes
with the key in ON until the light goes off. Then turn
the ignition to OFF before attempting to start
the engine again.
Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run
if you follow these guidelines:
Do not drive at any one speed, fast or slow,
for the rst 500 miles (805 km). Do not make
full-throttle starts.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-35for more information.
2-15

Engine Coolant Heater
Your vehicle may have this feature. In very cold
weather, 0°F (−18°C) or colder, the engine coolant
heater can provide 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. At temperatures
above 32°F (0°C), use of the coolant heater is not
required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located in
front of the coolant surge tank on the passenger’s
side. SeeEngine Compartment Overview on
page 5-12for more information on location.
3. Plug it into a normal, grounded 110-volt AC outlet.
{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 re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not 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 do not, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.
2-18

AUTOMATIC OVERDRIVE (D):This position is for
normal driving. If you need more power for passing,
and you are:
•Going less than 35 mph (56 km/h), push your
accelerator pedal about halfway down.
•Going about 35 mph (56 km/h) or more, push the
accelerator all the way down.
You will shift down to the next gear and have more
power.
Notice:If your vehicle seems to start up rather
slowly or not shift gears when you go faster, and
you continue to drive your vehicle that way, you
could damage the transaxle. Have your vehicle
serviced right away. You can drive in SECOND (2)
when you are driving less than 35 mph (55 km/h)
and AUTOMATIC OVERDRIVE (D) for higher speeds
until then.THIRD (3):This position is also used for normal driving.
However, 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.
•When going down a steep hill.
SECOND (2):This position gives you more power but
lower fuel economy than THIRD (3). 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:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of SECOND (2).
2-21

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 will not shift
into first gear until the vehicle is going slow enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
Second-Gear Start
Your vehicle is equipped with a second-gear start
feature. Place the shift lever in SECOND (2) gear to
provide more traction when you are starting on ice
or other slippery surfaces. The transaxle will be in
SECOND (2) gear when the vehicle begins to move.
After starting in SECOND (2) gear place the shift lever
in THIRD (3) or AUTOMATIC OVERDRIVE (D).
This feature is only for improved traction when the road
surface is slippery and is not intended for continuous
use or when the vehicle is stuck in sand, mud, ice, snow
or gravel.
Parking Brake
To set the parking brake,
push down the parking
brake pedal with your left
foot. If the ignition is
on, the brake system
warning light will come
on. SeeBrake System
Warning Light on
page 3-27.
To release the parking brake, hold the regular brake
pedal down with your right foot. Push down on the
parking brake pedal with your left foot. If the parking
brake is not released when you begin to drive, the brake
system warning light will come on and a chime will
sound warning you that the parking brake is still on.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and are parking on a hill,
seeTowing a Trailer on page 4-35.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll know how
fast you’re going, how much fuel you’re using, and many other things you will need to drive safely and economically.
Your vehicle has this instrument panel cluster, which includes indicator warning lights and gages that are explained
on the following pages.
3-23

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 awhile, 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:Modications made to the engine,
transaxle, exhaust, intake, 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 this light to come on.
Modications 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.
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 does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
•Light Flashing— A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Diagnosis and service may be required.
•Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
