transmission, or the speed is greater than 5 mph
(8 km/h) for a vehicle with a manual transmission.
The automatic door locking feature cannot be disabled.
Programmable Automatic Door
Unlock
Your vehicle can be programmed through the Driver
Information Center (DIC) to automatically unlock several
ways. SeeDIC Vehicle Personalization on page 3-40
for more information.
Rear Door Security Locks
Your vehicle has rear door security locks that prevent
passengers from opening the rear doors from the inside.
The rear door security locks
are located on the inside
edge of each rear door.
You must open the rear
doors to access them.
To set the locks, do the following:
1. Insert the key into the security lock slot and turn it
so the slot is in the horizontal position.

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.

Remote Trunk Release
To open the trunk from
inside the vehicle, press
the remote trunk release
button located inside
the driver’s storage
compartment located on
the lower left side of
the instrument panel.
SeeInstrument Panel Overview on page 3-4orDriver’s
Storage Compartment on page 2-35.
The remote trunk release will only work when either the
ignition is in OFF or ACC, or the vehicle speed is
less than 2 mph (3 km/h).
Emergency Trunk Release Handle
Notice:Do not use the emergency trunk release
handle as a tie-down or anchor point when securing
items in the trunk as it could damage the handle.
The emergency trunk release handle is only
intended to aid a person trapped in a latched trunk,
to open the trunk from the inside.
There is a glow-in-the-dark emergency trunk release
handle located on the inside of the trunk lid of your
vehicle. This handle will glow following exposure to light.
Pull the release handle and push the trunk lid open

2-11

Sun Visors
To block out glare, swing down the visor(s). The visors
can also be detached from the center mount and
swung to the side to cover the windows.
Visor Vanity Mirror
Your vehicle may have a driver’s side vanity mirror.
Swing down the sun visor and lift the cover to expose
the mirror.
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.
Content Theft-Deterrent
Your vehicle may have a
content theft-deterrent
alarm system.
Arming the System
With the ignition off, you can arm the system by doing
any one of the following:
Press the remote keyless entry transmitter lock
button.
Press the power door lock switch while the driver’s
door is open.
The system will arm after either of these things occur:
Thirty seconds after all the doors are closed.
Sixty seconds with any door open.
If you press the lock button on the transmitter a second
time while all the doors are closed, the system will
arm immediately. The system will still arm in 60 seconds
if a door is open. When the open door is closed, it will
also become armed.
The security light, located on the instrument panel
cluster, will turn on to indicate that arming has been
initiated. Once the system is armed, the security light will
ash once every three seconds.
If the security light is ashing twice per second, this
means that a door is open.
If you do not want to arm the system, you may lock the
car with the manual lock knobs on the doors.
2-14

Disarming the System
You can disarm the system by doing any one of the
following:
Press the remote keyless entry transmitter unlock
button.
Turn the ignition on.
If the system is armed and the trunk is opened using
the trunk release button on the transmitter, the system
will temporarily disarm itself and re-arm when the
trunk has been closed. This allows the you to exit the
vehicle, lock the doors using the transmitter, and
open the trunk using the transmitter without having to
disarm and re-arm the system.
Once the system is disarmed, the security light will stop
ashing.
How the System Alarm is Activated
If the system is armed, it can be activated by either:
Opening the driver’s door or trunk. This will cause
a ten second pre-alarm chirp followed by a
thirty second full alarm of horn and lights.
Opening any other door. This will immediately cause
a full alarm of horn and lights for thirty seconds.
When an alarm event has nished, the system will
re-arm itself automatically.
How to Turn Off the System Alarm
To turn off the system alarm, do one of the following:
Press the lock button on the remote keyless
entry transmitter. The system will then re-arm itself.
Press the unlock button on the remote keyless entry
transmitter. This will also disarm the system.
Insert the key in the ignition and turn it on. This will
also disarm the system.
Simulated Armed Mode
If you choose not to arm the system or if proper arming
cannot be completed, the Content Theft Deterrent
system will ash the security light once every three
seconds after a one minute delay with all the doors
closed. This ashing serves as a visual deterrent;
however, the system is not armed.
How to Detect a Tamper Condition
If you hear three chirps when you press the unlock, lock,
or trunk release buttons on the remote keyless
transmitter, it means that the content theft security
system alarm was activated previously.
2-15

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.
