2005 PONTIAC GTO battery

To prevent the battery from draining, the headlamp and
parking lamps will turn off when the ignition has been
turned off and the driver’s door is opened, because the
vehicle senses that the driver has forgotten to turn
off the lights. The lights stay off until the ignition is again
turned on, or the lights are turned back on manually
by the headlamp switch. The headlamps can be set to
automatically turn off after you have locked the
vehicle and walked away. To set or adjust the time
delay from when the driver’s door is opened to when the
lights automatically turn off, seeVehicle Personalization
on page 2-30. If you wish to have the lights on when
leaving the vehicle, wait until they have been
automatically turned off, then turn the light control first
to off, then to parking lamps or headlamps.
Fog Lamps
The control to the left of the steering wheel on the
instrument panel also controls the fog lamps.
-(Fog Lamp):When using the fog lamps, the
ignition must be on and the parking lamps or the
low-beam headlamps. If the high-beam headlamps are
activated or flashed, the fog lamps will turn off.
Pull the exterior lamp adjuster control out to turn the fog
lamps on, and push the control in to turn the fog
lamps off. The indicator light in the knob will come on
when the fog lamps are working.
Instrument Panel Brightness
Slide the control to
increase or decrease
the instrument
panel brightness.
Courtesy Lamps
When a door is open, the courtesy lamps will
automatically come on.

Dome Lamp
The dome lamp has three positions.
ON:In this position, the dome lamp is always on.
DOOR:In this position, the light automatically comes
on when a door is opened. It will turn off 30 seconds
after the last door is closed. If the ignition is turned on,
the light turns off immediately unless a door is open.
OFF:In this position, the dome lamp is always off, even
when a door is opened.
The dome lamp can be set to remain on for a preset
amount of time after the ignition has been turned
off. SeeVehicle Personalization on page 2-30.
Entry Lighting
The entry lighting feature illuminates the interior of the
vehicle before you enter. The interior lamps will come on
for 40 seconds when you unlock the doors using the
remote key buttons. After 40 seconds have elapsed, the
interior lamps will turn off. The lamps will turn off
before 40 seconds have elapsed if you do either of
the following:
•Lock all doors using the remote key buttons.
•Lock the doors manually using the lock knob.Entry lighting is canceled when any door is opened, but
the interior lights will stay on until all doors are closed.
The interior lamps may stay on for up to 25 seconds after
all doors have been closed if they have not been locked.
Front Reading Lamps
Your vehicle has reading lamps located in the dome
lamp. The lamps can be turned on and off manually by
pressing the side of each reading lamp.
Trunk Lamp
The trunk lamp comes on when you open your trunk.
Battery Run-Down Protection
Your vehicle has a battery run-down protection feature
designed to protect your vehicle’s battery.
It will activate when there has been no electrical change
for one hour, nothing has been turned on or off, after
the ignition has been turned to ON or LOCK.
Once activated, all the interior lamps will turn off
including dome, reading, glovebox, trunk.

The system is turned on if a door is opened, the vehicle
is unlocked, or the trunk is opened. Once the system
is turned on, the one hour battery protection time resets
to zero and the interior lamps will continue to operate
for another hour, or until the vehicle is locked.
The interior lamp system will shut down 10 seconds
after your vehicle is locked using either the key or the
remote key locking system. However, if an interior lamp,
such as the dome lamp, has been turned on manually
and is on at the time the vehicle is locked, the system will
not shut down after the normal 10 seconds. The one hour
battery protection will be activated instead.
The vehicle’s hazard lights will continue to operate at
all times.
Accessory Control
If you want the accessories to operate once the key has
been removed from the ignition, you must turn the
system on by either manually starting an accessory,
such as turning the radio on again. This will activate a
one hour timer that will operate accessories such as
the radio, accessory power outlet, and windshield wipers
before turning off. These actions will reset the timer to
zero. Likewise, if an accessory such as the radio is
turned on at any time during the one hour period, the
timer is reset to zero and all accessories will continue to
operate for another hour. To enable accessory control
after the system has been reset, you must turn the
ignition on and then off again.
Accessory Power Outlets
The vehicle has an
accessory power outlet
which can be used to plug
in electrical equipment.
The accessory power outlet is located inside the center
console. The power outlet is operational when the
ignition is turned to ON, LOCK, or when Retained
Accessories Power is in operation. SeeRetained
Accessory Power (RAP) on page 2-17.
Remove the tethered cap to use the outlet. When
not using the outlet, be sure to cover it with the
protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.

Charging System Light
The charging system light
will come on when you
turn on the ignition,
until the engine is started,
as a check to show
you it is working.
When the engine is running, the light should go out.
If the light illuminates and the Check Alternator message
on the trip computer stays on, or comes on while you
are driving you may have a problem with the electrical
charging system. It could indicate that you have a loose
generator drive belt or another electrical problem.
Have it checked right away. Driving while this light is on
could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
The Check Alternator message will remain until the
MODE button on the trip computer is pressed, but the
symbol will remain until the problem is fixed.
One-to-Four Shift Light (Manual
Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to turn off
this feature. This helps you get the best possible fuel
economy.
After shifting to FOURTH (4), you may downshift to a
lower gear if you prefer.
3-26

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.

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.

You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it or
CAUTION: (Continued)
CAUTION: (Continued)
smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on with
your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
