2005 Pontiac GTO Owner ManualM

Vehicle Damage Warnings
Also, in this manual you will find these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specific component, control, message,
gage, or indicator.
If you need help figuring out a specific name of a
component, gage, or indicator, reference the
following topics:
•Seats and Restraint Systems in Section 1
•Features and Controls in Section 2
•Instrument Panel Overview in Section 3
•Climate Controls in Section 3
•Warning Lights, Gages, and Indicators in Section 3
•Audio System(s) in Section 3
•Engine Compartment Overview in Section 5
iv

Your vehicle cannot be locked using the remote key if
the key is in the ignition and the ignition is ON.
The vehicle also cannot be locked if the driver’s door
is open.
To use the remote key to lock the doors, both doors must
be closed. If only the passenger’s door is open when the
lock button is pressed, the driver’s door will lock but the
passenger’s door will not. The horn will honk three times
to indicate that the passenger’s door has not locked.
The passenger’s door must be closed and the system
must be reset in order to lock both doors. To reset the
system, press the unlock button and then press the lock
button on the remote key.
Programmable Automatic
Door Locks
Your vehicle is equipped with an automatic door locking
feature which can be programmed through the trip
computer buttons and instrument panel center display.
It can be programmed to be on or off. SeeVehicle
Personalization on page 2-30for more information.
Your vehicle was programmed from the factory
to automatically lock when the shift lever is moved out
of PARK (P).
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot 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 and select the
control setting that will force outside air
into your vehicle. See Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-26.
2-8

Running the Engine While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-26.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 4-24.
{CAUTION:
It can be 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).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P)
(Automatic Transmission) on page 2-24.

Climate Controls
Climate Control System
With this system you can control the heating, cooling,
and ventilation for your vehicle.
Operation
To change the current mode, turn the right control to
select one of the following:
Y(Vent):This mode directs air to the instrument
panel outlets.
%(Bi-Level):This mode directs the air to the
instrument panel outlets and the floor outlets. This
position can be used for most winter driving.
[(Floor):This mode directs the air to the
floor outlets.
The right control can also be used to select defog or
defrost modes. Information on defogging and defrosting
can be found later in this section.
9(Fan):Turn the left control clockwise or
counterclockwise to increase or decrease the fan speed.
The fan must be on to run the air-conditioning
compressor.
>(Recirculation):This mode keeps outside air from
coming into the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or to
help heat or cool the air inside your vehicle more quickly.
Move the right control to this position to turn recirculation
on. Turn the air conditioning on when using recirculation.
Recirculation is not recommended for use over long
periods of time.
Temperature Control:Turn the center control
clockwise or counterclockwise to increase or decrease
the temperature inside your vehicle.
3-19

A/C (Air Conditioning):Press this button on the left
dial to turn the air-conditioning system on or off.
When A/C is pressed, an indicator light in the button will
come on to let you know that air conditioning is
activated.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the coolest temperature.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to choose from to
clear fog or frost from your windshield. Use the
defog mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more quickly.
Turn the right control to select the defog or
defrost modes.
-(Defog):This mode directs the air to the windshield
and to the floor outlets. When you select this mode,
the system turns off recirculation automatically.
The recirculation mode cannot be selected while in the
defog mode. Do not drive the vehicle until all the
windows are clear.
To help clear the side windows quickly while using air
conditioning, do the following:
1. Select the bi-level mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the temperature.
