2004 PONTIAC GTO transmission

Shift Speeds
{CAUTION:
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Don’t shift down
more than one gear at a time when you
downshift.
This chart shows when to shift to the next gear for the
best fuel economy.
Manual Transmission Recommended
Shift Speeds
1to2 2to3 3to4 4to5 5to6
16 mph
(25 km/h)22 mph
(35 km/h)30 mph
(48 km/h)40 mph
(65 km/h)50 mph
(80 km/h)
If your speed drops below 20 mph (32 km/h), or if the
engine is not running smoothly, you should downshift to
the next lower gear.
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.
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.

Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure the vehicle is in PARK (P) and the
parking brake is firmly set before you leave it. After
you’ve moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can
move the shift lever away from PARK (P), without first
pushing the shift lever button. If you can, it means
that the shift lever wasn’t fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you don’t 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) 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).
2-25

Shifting Out of Park (P)
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 in ON.
SeeAutomatic 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 OFF and remove the key.
2. Unclip the console cap and remove the screw
slightly to the right of the front center.
3. Remove console cap to expose the yellow
release lever.
4. Push the release lever forward and press the button
on the shift lever to move lever out of park.
5. Replace the console cap.
6. Have the vehicle fixed as soon as possible.
Parking Your Vehicle/Key Removal
Before leaving a manual transmission vehicle, fully press
the clutch pedal in, move the shift lever into
REVERSE (R), and firmly apply the parking brake. Once
the shift lever has been placed in REVERSE (R) with
the clutch pedal pressed in, you can turn the ignition key
to LOCK, remove the key, and release the clutch.

Pausing Cruise Control
To pause cruise control, press the brake pedal on
automatic transmissions or the clutch pedal on
manual transmissions, or press the ON-OFF/CANCEL
switch once.
This deactivates the cruise control but retains the speed
in its memory. The CRUISE ACTIVE message and
cruise control symbol on the display will turn off.
To regain the memory speed momentarily, turn the lever
up to the RES-ACCEL position, provided you are
travelling over 25 mph (40 km/h). Holding the lever in
the RES-ACCEL position for longer than one second
causes the vehicle to accelerate.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load, and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers find this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
Press the ON-OFF/CANCEL switch twice. The cruise
control symbol and message will turn off.
Pressing the ON-OFF/CANCEL switch once pauses the
cruise control but keeps the system ready and the
speed in memory.
A second press turns the system off completely and
wipes the speed memory clear.
A third press turns the system back on to ready, without
any speed memory.
Turning off the ignition completely turns off cruise
control and wipes the speed memory clear.
Cruise control will be canceled if the Traction Control
System (TCS) becomes active. SeeTraction Control
System (TCS) on page 4-8.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Exterior Lamps
The dial to the left of the
steering wheel on the
instrument panel controls
the following positions:
;(Parking Lamps):Turn the dial 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 dial 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 dial to AUTO

taillamps, sidemarker lamps, and parking lamps.
For more information see “Automatic Headlamp System”
following.
9(Off):Turn the switch to this position to turn all
lamps off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset.
The DRL system will make your low-beam headlamps
come on at a reduced brightness when the following
conditions are met:
•The ignition is on.
•The exterior lamp control is turned to AUTO and
the light sensor detects daytime light.
•The exterior lamp control is turned to the off
position.
•The parking brake is released.
•For vehicles with automatic transmissions, the shift
lever is not in PARK (P).

Speedometer
The speedometer shows vehicle speed in both miles
per hour (mph) and kilometers per hour (km/h).
Tachometer
The tachometer shows engine speed in revolutions
per minute (rpm).
For automatic transmission vehicle’s, under wide open
throttle acceleration, when the accelerator pedal is
pushed flat to the floor, it is possible that the tachometer
needle may briefly enter the lower end of the
tachometer’s red zone just prior to automatically
upshifting into a higher gear. This is normal during
wide open throttle acceleration and will not harm
the engine.
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.
Safety Belt Reminder Light
When the key is turned to
ON, the safety belt light
will come on and stay
on for several seconds and
a chime will be sounded
for eight seconds,
then it will flash
continuously until the
driver’s belt is buckled.
If the driver’s belt is already buckled, the light will not
come on.
