2004 PONTIAC GTO Owners Manual

Immobilizer Operation
Your vehicle may have a passive theft-deterrent system.
The system is an electronic engine immobilizer, which
disables the car, when the key is removed from the
ignition.
The system works when you turn the key to ON. The
key uses a transponder that matches an immobilizer
control unit in your vehicle. The correct key will start
the vehicle.
Your vehicle has a special key that works with the
theft-deterrent system. There is a transponder in the key
head. If the key is ever damaged, you may not be
able to start your vehicle.
When trying to start the vehicle, if the engine does not
start and the security light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.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 the fuse. SeeFuses
and Circuit Breakers on page 5-87for more information
on fuses. 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
who can service the theft-deterrent system to have
a new key made.
If you are ever driving and the security light comes on
and stays on, you will be able to restart your engine
if you turn it off. The theft-deterrent system, however, is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by the
theft-deterrent system at this time.
In an emergency, contact Roadside Assistance. See
Roadside Assistance Program on page 7-5.

Content Theft-Deterrent
Your vehicle has a theft-deterrent alarm system.
Arming the System
The alarm system is turned on when the LOCK button
on the key is pressed. Therefore, locking the doors
by pressing LOCK not only locks all the doors but, after
a short delay, also sets the alarm system. When the
system is armed, the alarm is triggered when any of the
doors, hood or trunk are opened or a hot-wire
attempted. The alarm system thinks a break-in has
occurred. An alarm sounds and the turn signals
and dome light will flash.When the alarm system is turned on, you may open the
trunk by pressing the trunk symbol button on the key.
This does not set off the alarm, but leaves the alarm
system on and undisturbed. Closing the trunk re-arms
the trunk alarm after a short delay.
The LOCK button on the key will not function when the
ignition is turned ON or the driver’s door is open.
Disarming the System
To disarm the system, press UNLOCK on the key or
turn the ignition to ON.
2-14

How to Detect a Tamper Condition
The exterior turn signals should flash twice when
returning to your vehicle and pressing UNLOCK on the
key. If they flash three times, an attempted break-in
has occurred while the vehicle was armed. If you wish
to find out what set the alarm off, turn the ignition on
and look at the trip computer display for the ALARM
ACTIVATED message being shown. The ALARM
ACTIVATED message will be displayed first for
one second, followed by the trigger point screens.
The trigger point screens will also be displayed for
one second. If more than one trigger point has been
activated, the display will show each trigger point screen
in sequence for one second, returning back to the
ALARM ACTIVATED screen. The alarm screens will be
shown in a continuous cycle until the trip computer
MODE button is pressed. The center display then
reverts to the last screen shown prior to the ignition
being off.
The possible trigger points are the following:
•The hood has been opened.
•The trunk has been opened.
•One of the doors has been opened.
•Hot wiring of the vehicle was attempted
(ignition on without key inserted).
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:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
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.
2-15

Ignition Positions
With the key in the ignition switch, you can turn it to
three different positions.
A (LOCK and ACCESSORY):This is the only position
from which you can insert or remove the key. When
the key is inserted and is in this position, all accessories,
electrical systems, and engine are off. If the key is
cycled back to this position the accessories will remain
on until the key is removed. Once the key is removed
the accessories will turn off. If the key is left inserted in
this position, a chime will sound when the driver’sdoor is opened to remind you the key has been left in
the ignition. The key can only be turned to this position if
the vehicle’s automatic transmission is in PARK (P).
To help guard against theft, your vehicle’s engine
is automatically disabled shortly after turning the key to
this position. This is indicated by the flashing padlock
symbol on the bottom left corner of the instrument panel.
The steering column is automatically locked when the
key is removed. To release the steering wheel, insert the
key again and turn it towards the front of the vehicle.
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.
B (ON and ACCESSORY):This position is where the
key returns to after you start your engine and release the
key. The ignition switch stays in ON when the engine
is running. But even when the engine is not running, you
can use ON to operate your electrical accessories
and to display some instrument panel warning lights.
C (START):This position starts the engine. When
the engine starts, release the key. The ignition switch
will return to ON for normal driving.
2-16

Retained Accessory Power (RAP)
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow the radio to
continue to work for one hour after the ignition is turned
to OFF. The windows will also be accessible for
15 minutes or until either door is opened.
Starting Your Engine
Automatic Transmission
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:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
The shift lever should be in neutral and the parking
brake engaged. Hold the clutch pedal to the floor and
start the engine. Your vehicle won’t start if the clutch
pedal is not all the way down – that’s a safety feature.
Starting Your Engine
1. With your foot off the accelerator pedal and the
parking brake firmly applied, 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, wait about 15 seconds and try
again to start the engine by turning the ignition
key 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. Don’t
run your engine at high speeds 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.
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.
2-17

Racing or Other Competitive Driving
See your warranty book before using your vehicle
for racing or other competitive driving.
Notice:If you use your vehicle for racing or other
competitive driving, the engine may use more
oil than it would with normal use. Low oil levels can
damage the engine. Be sure to check the oil level
often during racing or other competitive driving and
keep the level at or near 1 quart (1 L) above the
upper mark that shows the proper operating range
on the engine oil dipstick. For information on
how to add oil, seeEngine Oil on page 5-13. After
the competitive driving, remove excess oil so
that the level on the dipstick is not above the upper
mark that shows the proper operating range.
Automatic Transmission Operation
There are several different positions for your shift
lever. Push in the button on top of the shift lever when
shifting into position.PARK (P):The engine can be started in this position.
This position prevents the rear wheels from turning
and so should be selected, together with the parking
brake, when leaving the vehicle. Never select PARK (P)
while your vehicle is still moving.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not 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 will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). SeeShifting Into Park (P) on
page 2-24. If you are pulling a trailer, see
Towing a Trailer on page 4-35.
2-18

Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transmission
shift lock control system. You must have your foot
on the regular brakes before you can shift from
PARK (P) when the ignition key is in ON. The vehicle
will not shift from PARK (P) if the button is pressed
before the brake is applied. If you cannot shift out
of PARK (P), ease pressure on the shift lever, push the
shift lever all the way into PARK (P), and release the
shift lever button as you maintain brake application.
Then press the shift lever button and move the
shift lever into the desired gear. SeeShifting Out of
Park (P) on page 2-26.
REVERSE (R):Use this gear to back up. Never select
REVERSE (R) while your vehicle is still moving.
Reverse lights will operate when this position is selected
and the ignition is on. After reversing, make sure the
vehicle has fully stopped before selecting another gear
position. After selecting this position, pause for a
moment before accelerating to allow the transmission to
engage reverse gear.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
see If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-28.
NEUTRAL (N):In this position, your engine doesn’t
connect with the wheels. To restart when you’re already
moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed. This is
the out-of-gear position. You may then start a stalled
engine while the vehicle is still moving or stopped.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.
2-19

DRIVE (D):This is the most effective position for
normal or freeway driving. This position gives maximum
fuel efficiency, as the transmission can choose the
appropriate gear (1 through 4) for the existing load and
driving conditions.
After selecting DRIVE (D) from PARK (P) or
NEUTRAL (N), pause for a moment before accelerating,
to allow the transmission to engage the forward gear.
Use this position when towing.
THIRD (3):This position is also used for normal driving.
However, it offers more power and lower fuel economy
than DRIVE (D). Here are some times you might choose
THIRD (3) instead of DRIVE (D):
•When driving on hilly, winding roads.
•When towing a trailer, so there is less shifting
between gears.
•When going down a steep hill.SECOND (2):This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you
would also want to use your brakes off and on.
FIRST (1):This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1), the transmission
won’t shift into first gear until the vehicle is going slowly
enough.
Remember to move the shift lever back to DRIVE(D) so
that the transmission again upshifts into higher gears.
Even though the shift lever may be in FIRST (1),
the transmission does not select first gear until vehicle
speed is less that 35 mph (56 km/h).
