The rear doors of your vehicle cannot be opened from
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.
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 and open the door from
the outside.
2. Move the lever all the way down.
3. Do the same for the other rear door.
The rear door locks will now work normally.Anti-Lockout Feature
The power door locks will not work if the key is left in
the ignition with the driver's door open. You can
override this feature by holding the power door lock
switch for more than three seconds, unless the engine
is running.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from the inside. Then get out and
close the door. You may also use the lock button on the
remote keyless entry transmitter after shutting the doors.
If your vehicle has a theft
-deterrent system,
see ªUniversal Theft
-Deterrentº in the Index.

2-15 Remote Trunk Release Lockout (Option)
The trunk release lockout
switch in the trunk allows
you to secure items in
the trunk.
By pressing the left side of the valet switch, the remote
trunk release button below the driver's door armrest will
be disabled. Push the right side of the valet switch to
enable the remote trunk release button to work again.
Trunk Security Override (Option)
Pressing the trunk symbol on the remote keyless entry
transmitter opens the trunk even if the remote trunk
release lockout switch is activated.
Trunk Lid
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:
1. Make sure all other windows are shut.
2. Turn the fan on your heating or cooling
system to its highest speed with the
setting on ECON or VENT. That will
force outside air into your vehicle. See
ªComfort Controlsº in the Index.
3. If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.

3. Get out of the car, close the door and wait for the
SECURITY light to go out.
4. Then, reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown. To
replace the fuse, see ªFuses and Circuit Breakersº in
the Index.
If the alarm does not sound, or the vehicle's lamps do
not flash, the vehicle should be serviced by an
authorized service center.
PASS-Key
II
Your vehicle is equipped with the PASS-Key II
(Personalized Automotive Security System)
theft
-deterrent system. PASS-Key II is a passive
theft
-deterrent system. It works when you insert or
remove the key from the ignition.
PASS
-Key II uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.When the PASS
-Key II system senses that someone is
using the wrong key, it shuts down the vehicle's starter
and fuel systems. For about three minutes, the starter
won't work and fuel won't go to the engine. If someone
tries to start your vehicle again or uses another key
during this time, the vehicle will not start. This
discourages someone from randomly trying different
keys with different resistor pellets in an attempt to make
a match.
The ignition key must be clean and dry before it's
inserted in the ignition or the engine may not start. If the
engine does not start and the SECURITY light is on, the
key may be dirty or wet. Turn the ignition off.
Clean and dry the key. Wait about three minutes and try
again. If the starter still won't work, and the key appears
to be clean and dry, wait about three minutes and try
another ignition key. At this time, you may also want to
check the fuse (see ªFuses and Circuit Breakersº in the
Index). If the starter won't work with the other key, your
vehicle needs service. If your vehicle does start, the first
ignition key may be faulty. See your dealer or a
locksmith who can service the PASS
-Key II.

If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won't work. The
SECURITY light will flash. But you don't have to wait
three minutes before trying another ignition key.
See your dealer or a locksmith who can service the
PASS
-Key II to have a new key made.
If you're ever driving and the SECURITY light comes
on and remains on, you will be able to restart your
engine if you turn it off. Your PASS
-Key II system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS
-Key II system.
If you lose or damage a PASS
-Key II ignition key, see
your dealer or a locksmith who can service PASS
-Key II
to have a new key made. 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
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.

2-21 Retained Accessory Power (If Equipped)
If you have this option, after you turn the ignition off
and even remove the key, you will still have electrical
power to such accessories as the radio and power
windows for up to 10 minutes. Power is turned off if you
open a door.
Always leave your key in LOCK. If you leave your key
in any other position than LOCK, your battery will
discharge prematurely.
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.
Starting Your V6 Engine
1. Without pushing 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 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 doesn't start right away, hold your key in
START for about three to five seconds at a time until
your engine starts. Wait about 15 seconds between
each try to help avoid draining your battery or
damaging your starter.
