2009 PONTIAC G5 transmission

Automatic Transmission Operation
If the vehicle has an automatic transmission, the
shift lever is located on the console between the seats.
There are several different
positions for the automatic
transmission.
P (Park):This position locks the front wheels. It is the
best position to use when starting the engine because
the vehicle cannot move easily.{CAUTION:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
rmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park (Automatic Transmission) on page 2-31.
If you are pulling a trailer, seeTowing a Trailer
(Automatic Transmission) on page 4-31orTowing
a Trailer (Manual Transmission) on page 4-38.
2-26

Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to fully
apply the regular brakes rst and then press the shift
lever button before the vehicle can shift from P (Park)
when the ignition key is in ON/RUN. If the vehicle cannot
shift out of P (Park), ease pressure on the shift lever
and push the shift lever all the way into P (Park) as you
maintain brake application. Then press the shift lever
button and then move the shift lever into another gear.
SeeShifting Out of Park (Automatic Transmission)
on page 2-33.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
R (Reverse):Use this gear to back up.
To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-21.
N (Neutral):In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is rmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle.
D (Drive):This position is for normal driving with the
automatic transmission. It provides the best fuel
economy. If you need more power for passing and
you are:
Going less than about 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h), push the accelerator
all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-14.
2-27

I (Intermediate):This position is also used for normal
driving. However, it reduces vehicle speed without using
the brakes for slight downgrades where the vehicle
would otherwise accelerate due to steepness of grade.
If constant upshifting or downshifting occurs while
driving up steep hills, this position can be used to
prevent repetitive types of shifts. You might choose
I (Intermediate) instead of D (Drive) when driving
on hilly, winding roads and when towing a trailer,
so that there is less shifting between gears.
L (Low):This position reduces vehicle speed more
than I (Intermediate) without actually using the brakes.
You can use it on very steep hills, or in deep snow
or mud. If the shift lever is put in L (Low), the
transmission will not shift into a low gear until
the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. The repair
will not be covered by the vehicle warranty. If you
are stuck, do not spin the tires. When stopping on
a hill, use the brakes to hold the vehicle in place.Manual Transmission Operation
This is the shift pattern.
Here is how to operate the manual transmission:
1 (First):Press the clutch pedal and shift into 1 (First).
Then, slowly let up on the clutch pedal as you press
the accelerator pedal.
You can shift into 1 (First) when the vehicle is traveling
less than 20 mph (32 km/h). If you have come to a
complete stop and it is hard to shift into 1 (First), put the
shift lever in N (Neutral) and let up on the clutch pedal.
Press the clutch pedal back down. Then shift into
1 (First).
2-28

2 (Second):Press the clutch pedal as you let up on the
accelerator pedal and shift into 2 (Second). Then, slowly
let up on the clutch pedal as you press the accelerator
pedal.
3 (Third), 4 (Fourth) and 5 (Fifth):Shift into 3 (Third),
4 (Fourth) and 5 (Fifth) the same way you do for
2 (Second). Slowly let up on the clutch pedal as
you press the accelerator pedal down.
To stop, let up on the accelerator pedal and press
the brake pedal. Just before the vehicle stops, press
the clutch pedal and the brake pedal, and shift to
N (Neutral).
N (Neutral):Use this position when you start or idle the
engine.
R (Reverse):To back up, press down the clutch pedal
and shift into R (Reverse).
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
Also, use R (Reverse), along with the parking brake, for
parking the vehicle.Shift Speeds
{CAUTION:
If you skip a gear when you downshift, you could
lose control of the vehicle. You could injure
yourself or others. Do not shift down more than
one gear at a time when you downshift.
Up-Shift Light
If the vehicle has a manual
transmission, there may be
an up-shift light. This light
will show you when to shift
to the next higher gear for
the best fuel economy.
When this light comes on, you can shift to the next
higher gear if weather, road, and traffic conditions let
you. For the best fuel economy, accelerate slowly
and shift when the light comes on.
While accelerating, it is normal for the light to go on and
off if you quickly change the position of the accelerator.
Ignore the light when downshifting.

Shifting Into Park (Automatic
Transmission)
{CAUTION:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake rmly set. The vehicle can roll. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, use the steps that follow.
If you are pulling a trailer, seeTowing a Trailer
(Automatic Transmission) on page 4-31orTowing
a Trailer (Manual Transmission) on page 4-38.To shift into P (Park):
1. Hold the brake pedal down and set the parking
brake. SeeParking Brake on page 2-30for more
information.
2. Move the shift lever into P (Park) by holding in the
button on the shift lever and pushing the lever all
the way toward the front of the vehicle.
3. Turn the ignition key to LOCK/OFF.
2-31

Leaving the Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly if
the shift lever is not fully in P (Park) 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 the vehicle with the engine running.
If you have to leave an automatic transmission vehicle
with the engine running, be sure the vehicle is in
P (Park) and the parking brake is rmly set before you
leave it. After you have moved the shift lever into
P (Park), hold the brake pedal down. Then, see if you
can move the shift lever away from P (Park) without rst
pushing the button. If you can, it means that the shift
lever was not fully locked into P (Park).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift into
P (Park) properly, the weight of the vehicle may put too
much force on the parking pawl in the transmission.
You may nd it difficult to pull the shift lever out of
P (Park). This is called “torque lock.” To prevent torque
lock, set the parking brake and then shift into P (Park)
properly before you leave the driver seat. To nd
out how, seeShifting Into Park (Automatic Transmission)
on page 2-31.
Move the shift lever out of P (Park) before you release
the parking brake.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take some of
the pressure from the parking pawl in the transmission,
so you can pull the shift lever out of P (Park).

Shifting Out of Park
(Automatic Transmission)
This vehicle is equipped with an electronic shift lock
release system. The shift lock release is designed to:
Prevent ignition key removal unless the shift
lever is in P (Park) with the shift lever button fully
released, and
Prevent movement of the shift lever out of
P (Park) unless the ignition is in ON/RUN or ACC/
ACCESSORY and the regular brake pedal is applied.
The shift lock release is always functional except in the
case of a an uncharged or low voltage (less than 9 volt)
battery.
If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting on page 5-34for more information.
To shift out of P (Park):
1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the desired position.If you still are unable to shift out of P (Park):
1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift
lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from P (Park),
consult your dealer/retailer or a professional towing
service.
Parking the Vehicle
(Manual Transmission)
Before leaving the vehicle, fully press the clutch pedal
down, move the shift lever into R (Reverse), and rmly
apply the parking brake. Once the shift lever has been
placed in R (Reverse) with the clutch pedal pressed
down, the ignition key can be turned to LOCK/OFF,
then remove the key and release the clutch pedal.
SeeManual Transmission Operation on page 2-28.

Running the Vehicle 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 a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that has
no fresh air ventilation. For more information, see
Engine Exhaust on page 2-34.
{CAUTION:
It can be dangerous to get out of the vehicle
if the automatic transmission shift lever is not
fully in P (Park) with the parking brake rmly set.
The vehicle can roll. Do not leave the 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 the vehicle will not move, even when you are
on fairly level ground, always set the parking brake
and move the shift lever to P (Park).
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park (Automatic Transmission)
on page 2-31.
