ECU PONTIAC GTO 2005 Owner's Manual

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 5-86for 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.
SeeRoadside Assistance Program on page 7-6.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.

Exterior Lamps
The switch to the left of
the steering wheel on the
instrument panel controls
the following:
;(Parking Lamps):Turn the switch to this position
to turn on the parking lamps, together with the
taillamps, sidemarker lamps, license plate lamps, and
instrument panel lights.
2(Headlamps):Turn the switch to this position to
turn on the headlamps, together with the parking lamps,
taillamps, sidemarker lamps, and license plate lamps.AUTO (Automatic Headlamps):Turn the switch to
AUTO to provide for automatic operation of the
headlamps, taillamps, sidemarker lamps, and parking
lamps. For more information seeAutomatic Headlamp
System on page 3-14.
9(Off):Turn the switch to this position to turn all
lamps off.
Headlamps
When the headlamps are switched on, the instrument
panel is automatically illuminated. Once illuminated, you
can adjust their brightness. Some illuminated areas
of the vehicle have been linked to the brightness control,
such as the trip computer, headlamp switch, radio,
etc. This means that the interior lights can be adjusted
to your preference. When the headlamps are turned
off and back on again, the brightness level reverts to the
last adjusted setting.
Your vehicle is designed to provide additional security,
when returning to the vehicle at night. When the
UNLOCK or LOCK button on the key is used, the car’s
exterior lights will come on for a preset time or until
the car is relocked. This feature only works if the
headlamp control is in the AUTO or headlamp positions.
To set or adjust the time the headlamps stay on after
the UNLOCK button has been pressed, seeVehicle
Personalization on page 2-30.
3-13

Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
Security Light
This light flashes when the
vehicle security system is
activated.
Please seeTheft-Deterrent Systems on page 2-13for
more information.
Fog Lamp Light
This light will come on
when the fog lamps are
in use.
The light will go out when the fog lamps are turned off.
SeeFog Lamps on page 3-15for more information.
Highbeam On Light
This light will come on
when the high-beam
headlamps are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8.

Theft-Deterrent Feature
Your vehicle’s radio has an electronically coded security
system. The system recognizes the vehicle which the
radio has been installed. If the radio is kept in the
vehicle, the PIN should not be required, even if the
battery or the radio has been removed and reinstalled.
If the link between your vehicle and the radio is
disrupted, the radio will prompt you for a four-digit
PIN code to be entered.
The PIN is supplied on the security card. As the pin is
the only means of enabling operation of the radio, place
the security card in a safe place. Do not leave the
security card in the glovebox. The PIN should also be
written down and kept with other important documents.
If the security card is lost and the PIN is not recorded,
the PIN can be requested from your GM dealer,
after supplying proof of ownership. There may be a
charge for this service.
When the radio and vehicle are turned off, the blinking
red light indicates that the radio is armed.
Security Release Procedure
To type in the PIN code, do the following:
1. Turn the ignition to ON.
2. Turn the radio on. CODE____will appear on
the display.
3. Use the preset buttons to enter the PIN code.
If the wrong PIN code is entered, the radio will display
CODE ERR WAIT.
After a few seconds, the radio will display
CODE 2____,indicating that this is the
second attempt. The correct code should now
be entered. After three attempts, the radio will
display LOCK OUT 1 HR. After 1 hour, the radio will
allow another three attempts to enter the PIN.

Winter Driving
Here are some tips for winter driving:
•Have your vehicle in good shape for winter.
•You may want to put winter emergency supplies in
your trunk.
Also seeTires on page 5-52.Include an ice scraper, a small brush or broom, a
supply of windshield washer fluid, a rag, some winter
outer clothing, a small shovel, a flashlight, a red
cloth, and a couple of reflective warning triangles. And,
if you will be driving under severe conditions, include
a small bag of sand, a piece of old carpet, or a couple of
burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.

And, if you do have a heavy load, you should spread
it out.
{CAUTION:
Do not load your vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or either
the maximum front or rear Gross Axle Weight
Rating (GAWR). If you do, parts on your
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of your vehicle.
If you put things inside your vehicle — like suitcases,
tools, packages, or anything else — they will go as fast
as the vehicle goes. If you have to stop or turn
quickly, or if there is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the rear area of your vehicle.
Try to spread the weight evenly. If you
have fold-down rear seats, you will nd
four anchors on the back wall of your
trunk. You can use these anchors to tie
down lighter loads. They are not strong
enough for heavy things, however, so put
them as far forward as you can in the
trunk or rear area.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.

If the coolant overflow reservoir is completely empty,
add coolant to the radiator. SeeEngine Overheating on
page 5-26.
{CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the
radiator. Never turn the radiator pressure
cap — even a little — when the engine and
radiator are hot.
Occasionally check the coolant in the radiator. For
information on how to add coolant to the radiator, see
Cooling System on page 5-29.
Radiator Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
SeeEngine Compartment Overview on page 5-12for
information on location.
Engine Overheating
Immediate action is required if your engine overheats.
This is indicated by the coolant temperature gage
and the Engine Temp Hot message on the trip computer
display. SeeEngine Coolant Temperature Gage on
page 3-28andTrip Computer on page 3-33for more
information.
