Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors or in
different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols

Section 2 Features and Controls
2-1

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, the power door lock switch, or by
lifting the rear door manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert the key into the security lock slot and turn it
so the slot is in the vertical position.
Lockout Protection
If you press the power door lock switch when the key is
in the ignition and any door is open, all the doors will
lock and the driver’s door will unlock. Be sure to remove
the key from the ignition when locking your vehicle.
The lockout protection can be overridden by pressing
and holding the power door lock in the lock position for
three seconds.
Trunk
To release the trunk lid from the outside, use the key or
the remote keyless entry transmitter.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-30.
2-10

Passive Arming
If passive arming is enabled through the Driver
Information Center (DIC), the system will arm itself
60 seconds after cycling the ignition off and closing
all doors.
Passlock®
Your vehicle is equipped with 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, fuel is disabled.
During normal operation, the security light will go off
approximately three seconds after the key is turned to
RUN following an engine start. The security light is
located on the instrument panel cluster. SeeInstrument
Panel Cluster on page 3-22.
If the engine stalls and the security light ashes, wait
until the light stops ashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock
®system is
not working properly and must be serviced by yourdealer. Your vehicle is not protected by Passlock
®at
this time. See your dealer for service. Or seeRoadside
Assistance Program on page 7-6for more information.
You may also want to check the fuses. SeeFuses
and Circuit Breakers on page 5-91.
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 (Manual Transaxle) on page 4-37or
Towing a Trailer (Automatic Transaxle) on
page 4-38for more information.
2-16

Ignition Positions
With the key in the ignition switch, you can turn it to
four different positions.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in. If
it is, turn the steering wheel left and right while you
turn the key hard. If none of this works, then
your vehicle needs service.
9(LOCK):This position locks your steering column. It
is a theft-deterrent feature. You will only be able to
remove your key when the ignition is turned to LOCK.
If you have an automatic transaxle, the ignition
switch cannot be turned to LOCK unless the shift lever
is in PARK (P).
{CAUTION:
If you have a manual transaxle removing the key
from the ignition switch will lock the steering
column and result in a loss of ability to steer the
vehicle. This could cause a collision. If you need
to turn the engine off while the vehicle is
moving, turn the key to ACC.
ACC (ACCESSORY):This position operates some of
your electrical accessories. It unlocks the steering wheel
and ignition.
R(RUN):This is the position the switch returns to after
you start your engine and release the switch. The
switch stays in the RUN position when the engine is
running. But even when the ignition is not running, you
can use RUN to operate your electrical accessories
and to display some warning and indicator lights.
/(START):This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to RUN for normal driving.
A warning tone will sound if you open the driver’s door
when the key has not been removed from the ignition.
2-17

Retained Accessory Power (RAP)
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow the radio, power
windows and sunroof to continue to work up to
10 minutes after the ignition is turned off.
Your vehicle’s radio will work when the ignition key is in
RUN or ACC. Once the key is turned off, the radio,
power windows and sunroof will continue to work for up
to 10 minutes or until any door is opened.
Starting the Engine
Automatic Transaxle
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
Manual Transaxle
The shift lever should be in NEUTRAL and the parking
brake engaged. Hold the clutch pedal to the oor
and start the engine. Your vehicle will not start if the
clutch pedal is not all the way down — that is a safety
feature.
2-19

Starting Procedure
1. With your foot off the accelerator pedal, turn your
ignition to START. When the engine starts, let go
of the key. The idle speed will go down as your
engine gets warm.
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 it does not start, wait about 15 seconds and try
again to start the engine by turning the ignition to
START. Wait about 15 seconds between each try.
When your engine has run about 10 seconds to
warm up, your vehicle is ready to be driven. Do not
run your engine at high speed when it is cold.
If the weather is below freezing (32°F or 0°C), let
the engine run for a few minutes to warm up.3. If your engine still will not start, or starts but then
stops, it could be ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
oor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briey but then stops again, do the same thing,
but this time keep the pedal down for ve or
six seconds. This clears the extra gasoline from the
engine.
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 do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.
Engine Coolant Heater
If your vehicle has this feature, in very cold weather
0°F (−18°C) or colder, the engine coolant heater can
help. You will 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. At temperatures above 32°F (0°C),
use of the coolant heater is not required.
2-20

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. For
the 2.2L engine, the electrical cord is located on the
passenger’s side of the vehicle between the strut
and the air cleaner/lter. For the 2.0L engine,
the electrical cord is located on the passenger’s
side of the vehicle near the strut.
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
a GM dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.
