2005 PONTIAC GTO light

After shifting to FOURTH (4), you may downshift to a
lower gear if you prefer.
Notice:Forcing the shift lever into any gear except
FOURTH (4) when the 1 TO 4 SHIFT light comes
on may damage the transmission. Shift only from
FIRST (1) to FOURTH (4) when the light comes on.
This light will come on when:
•The engine coolant temperature is higher than
169°F (76°C),
•you are going 15 to 19 mph (24 to 31 km/h) and
•you are 21 percent throttle or less.
SeeOne-to-Four Shift Light (Manual Transmission) on
page 3-26andTrip Computer on page 3-33for more
information.
Parking Brake
To set the parking brake, pull up on the parking brake
handle without pressing the release button. If the ignition
is on, the brake system warning light will come on.
SeeBrake System Warning Light on page 3-27.
To release the parking brake, hold the regular brake
pedal down. Pull the parking brake handle up until you
can press the release button. Hold the release button
in as you move the brake handle all the way down.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.

Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may find it difficult to move
the shift lever out of PARK (P). This is called torque lock.
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave the
driver’s seat. To find out how, seeShifting Into Park (P)
(Automatic Transmission) on page 2-24.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push your vehicle uphill. This should take some of
the pressure from the parking pawl in the transmission,
so you can move the shift lever out of PARK (P).
Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift lock
control system. You must fully apply your regular brakes
before you can press the button on the shift lever to
shift from PARK (P) while the ignition is ON. See
Automatic Transmission Operation on page 2-18.If you cannot shift out of PARK (P), ease pressure on
the shift lever by pushing it all the way into PARK (P)
while keeping the brake pedal down. Release the
shift lever button. Then move the shift lever out of
PARK (P), being sure to press the shift lever button.
Shift Lock Release
If you ever hold the brake pedal down but still cannot
shift out of PARK (P), try this:
1. Turn the ignition to LOCK to remove the key.
2. Remove the front console rubber insert, located in
front of the shift lever, by lifting upwards.
3. Remove the screw slightly to the right of the
front center.
4. Open the console storage compartment and pry
the console cover assembly from the console.
The cover is attached in six places.
5. Insert a tool into the opening in front of the shift
lever and move the yellow release lever forward.
6. Press the button on the shift lever to move lever out
of park.
7. Replace the console cap.
8. Have the vehicle fixed as soon as possible.

Turn and Lane-Change Signals
To signal a turn, move the lever all the way up to signal
right turn and all the way down to signal a left turn.
When the turn is finished, the lever will return
automatically.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
flash rapidly, a signal bulb may be burned out and other
drivers won’t see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you signal
a turn, check for burned-out bulbs and then check the
fuse. SeeFuses and Circuit Breakers on page 5-86.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high
beam with the headlamps on, push the turn
signal/multifunction lever away from you. The headlamps
will change from low beam to high beam.
When the high beams are
on, a light on the
instrument panel cluster
also will be on if the
ignition is on.
If the fog lamps are on when the high-beam headlamps
are activated, the fog lamps will turn off. The fog
lamp indicator in the instrument panel cluster will
turn off.

;(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.

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.
