To close the liftgate, pull down on the handle, then
firmly shut the liftgate. Don't drive with the liftgate
open, even slightly. See ªEngine Exhaustº in the Index.
A message in your instrument panel cluster will warn
you if the liftgate is not completely closed. See ªRear
Hatch Ajar Warning Messageº in the Index.
Theft
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.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transaxle. Also remember to lock the doors.

PASS-Key
III
Your vehicle is equipped
with the PASS
-Key III
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key III is a passive
theft
-deterrent system. This
means you don't have to do
anything different to arm or
disarm the system. It works
when you insert or remove
the key from the ignition.
Your PASS
-Key III system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received,
including interference that may cause undesired operation.This device complies with RSS
-210 of Industry Canada.
Operation is subject to the following two conditions: (1) this
device may not cause interference, and (2) this device must
accept any interference received, including interference that
may cause undesired operation of the device.
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
PASS
-Key III uses a radio frequency transponder in the
key that matches a decoder in your vehicle.
When the PASS
-Key III system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. The starter will not work and fuel will
stop being delivered to the engine. Anyone using a
trial
-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
If the engine does not start and the security message
comes on, the key may have a damaged transponder.
Turn the ignition off and try again.

2-42
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check fuse 12. If the engine still
does not start with the other key, your vehicle needs
service. If your vehicle does start, the first key may
be faulty. See your dealer or a locksmith who can
service the PASS
-Key III to have a new key made.
See ªFuses and Circuit Breakersº in the Index.
It is possible for the Pass
-Key III decoder to learn the
transponder value of a new or replacement key. Up to
10 additional keys may be programmed for the vehicle.
This procedure is for learning additional keys only. If all
the currently programmed keys are lost or do not
operate, you must see your dealer or a locksmith who
can service PASS
-Key III to have keys made and
programmed to the system.
See your dealer or a locksmith who can service
PASS
-Key III to get a new key blank that is cut exactly
as the ignition key that operates the system.To program the new key:
1. Verify the new key has ªPK3º stamped on it.
2. Insert the ignition key in the ignition and start the engine.
If the engine will not start see your dealer for service.
3. After the engine has started, turn the key to OFF and
remove the key.
4. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
5. The security message will turn off once the key has
been programmed. It may not be apparent that the
security message went on due to how quickly the key
is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the security message comes on
and stays on, you will be able to restart your engine if you
turn it off. Your PASS-Key III system, however, is not
working properly and must be serviced by your dealer.
Your vehicle is not protected by the PASS
-Key III system
at this time.
If you lose or damage a PASS
-Key III key, see your
dealer or a locksmith who can service PASS
-Key III to
have a new key made. In an emergency, call Chevrolet
Roadside Assistance. See ªRoadside Assistanceº in the
Index for more information.

NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
OFF (C): This position unlocks the steering wheel,
ignition and transaxle, but does not send electrical
power to any accessories. Use this position if your
vehicle must be pushed or towed, but never try to
push
-start your vehicle. A warning chime will sound if
you open the driver's door when the ignition is off and
the key is in the ignition.RUN (D): This is the position to which the switch
returns after you start your engine and release the
switch. The switch stays in RUN when the engine is
running. But even when the engine is not running,
you can use RUN to operate your electrical power
accessories, and to display some instrument panel
warning lights.
START (E): This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to RUN for normal driving.
If the engine is not running, ACCESSORY and RUN are
positions that allow you to operate your electrical
accessories, such as the radio.
Retained Accessory Power (RAP)
With RAP, the power windows (option), the power rear
quarter windows (if equipped), audio system and the
optional electronic level control (ELC) will continue to
work up to 10 minutes after the ignition key is turned to
OFF and none of the doors are opened.

2-45
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position
-- that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only.
NOTICE:
Don't try to shift to PARK (P) if your vehicle is
moving. If you do, you could damage the
transaxle. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine warms up.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If the engine doesn't start in 10 seconds, push the
accelerator pedal about one
-quarter of the way down
while you turn the key to START. Do this until the
engine starts. As soon as it does, let go of the key.

2-46
3. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for a maximum of 15 seconds. This clears
the extra gasoline from the engine. If the engine still
won't start or starts briefly but then stops again,
repeat Step 1 or 2, depending on temperature.
When the engine starts, release the key and the
accelerator pedal.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
Engine Coolant Heater (If Equipped)
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.

2-47
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
electrical cord is located on the driver's side of the
engine compartment.
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 fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-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.
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'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

2-48
Automatic Transaxle Operation
Maximum engine speed is limited when you're in
PARK (P) or NEUTRAL (N), to protect driveline
components from improper operation.
There are several different positions for your shift lever.
PARK (P): This gear position locks your front wheels.
It's the best position to use when you start your engine
because your vehicle can't move easily.
Ensure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transaxle shift lock control system. You have to fully
apply your regular brakes before you can shift from
PARK (P) when the ignition key is in RUN. As you step
on the brake pedal, while in PARK (P), you may hear a
click from the solenoid of the system. This ensures that
the system is operating properly.If you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
move the shift lever into the gear you wish. See
ªShifting Out of PARK (P)º in this section.
CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
See ªShifting Into PARK (P)º in the Index. If
you're pulling a trailer, see ªTowing a Trailerº in
the Index.
