easier to use your power door locks at any time either
manually or with the power door lock switches.
When the driver leaves the vehicle and pushes the power
door lock switch to LOCK, three chimes will be heard.
The doors will not lock. Seven seconds after the driver's
door has been closed, all of the doors will lock, the
lamps will flash and the horn will chirp.If the driver opens another door before the seven
seconds, the doors will not lock until seven seconds after
the last door is closed.
If the power door lock switch is pressed to LOCK twice
when leaving the vehicle, the doors will immediately lock.
Rear Door Security Locks

with rear door security
locks that help prevent
passengers from opening
the rear doors of your
vehicle from the inside.

To use the security locks:
1. Move the switch up.
2. Close the door.
3. Do the same thing on the other rear door.

The rear doors of your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open a rear door when the security lock is on:
1. Unlock the door from the inside.
2. Then open the door from the outside.
If you don't cancel the security lock feature, adults or
older children who ride in the rear won't be able to open
the rear door from the inside. You should let adults and
older children know how these security locks work, and
how to cancel the locks.
To cancel the rear door lock:
1. Unlock the door from the inside and open it from
the outside.
2. Move the switch down.
3. Do the same for the other rear door.
The rear doors will now work normally.Anti-Lockout Protection
Anti-Lockout Protection is a standard feature intended
to provide enhanced security and convenience. This
feature prevents a driver who has left the keys in the
ignition from locking the doors, using the power door
locks while any door is open.
To override this feature, when the key is in the ignition
and a door is open, hold the power door lock switch for
three seconds.
This feature cannot guarantee that you will never be
locked out of your vehicle. If you don't leave the keys in
the ignition, or if you use the manual door lock, or if
you use the remote keyless entry transmitter (if
equipped), you could still lock your keys inside your
vehicle. Always remember to take your keys with you.
Leaving Your Vehicle
If you are leaving your vehicle, open your door and set
the locks from the inside, then get out and close the door.

2-11 Resynchronization
Your keyless entry system is equipped with a security
system that prevents anyone from recording and playing
back your signal. The transmitter does not send the same
signal twice to the receiver. The receiver will not respond
to a signal that has been sent to it more that once.
To resynchronize your transmitter and receiver, follow
these directions:
1. Stand close to your vehicle.
2. Press and hold the LOCK and UNLOCK buttons
on the transmitter at the same time.
3. Hold the buttons for five seconds. In this time, the
doors should lock and unlock once. This confirms
the resynchronization. If the doors do not lock and
unlock, see your dealer for service.
Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder or use the remote keyless
entry transmitter (if equipped).
CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't 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 with the setting
on VENT. That will force outside air into
your vehicle. See ªComfort Controlsº in
the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

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 five seconds after the key is turned to
the ON ignition position.
If the engine stalls and the SECURITY light flashes,
wait until the light stops flashing 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 your dealer. Your vehicle
is not protected by Passlock at this time. You may also
want to check the fuse (see ªFuses and Circuit Breakersº
in the Index). See your dealer for service.
In an emergency, call the Pontiac Roadside Assistance
Center at 1
-800-ROADSIDE or 1-800-762-3743.
(In Canada, call 1
-800-268-6800.)
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the
long run if you follow these guidelines:

Don't drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't 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.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.

radio is not protected by the feature. If THEFTLOCK is
activated, your radio will not operate if stolen.
