2009 PONTIAC G8 Owners Manual

A (LOCK/OFF):This is the only
position from which you can remove
the key. This locks the steering
wheel, ignition and automatic
transmission.
On vehicles with an automatic
transmission, the shift lever must
be in P (Park) to turn the ignition
switch to the LOCK/OFF position.
The ignition switch can bind in
the LOCK/OFF position with the
wheels turned off center. If this
happens, move the steering wheel
from right to left while turning the key
to ACC/ACCESSORY. If this doesn’t
work, then the vehicle needs service.
B (ACC/ACCESSORY):This
position provides power to some
of the electrical accessories.
It unlocks the steering wheel and
ignition. The transmission is
also unlocked in this position
on automatic transmission
vehicles. To move the key from
ACC/ACCESSORY to LOCK/OFF,
push in the key and then turn it
to LOCK/OFF.C (ON/RUN):The ignition switch
stays in this position when the
engine is running. This position can
be used to operate the electrical
accessories, including the ventilation
fan and 12 volt power outlet, as
well as to display some warning and
indicator lights.
The battery could be drained
if you leave the key in the
ACC/ACCESSORY or ON/RUN
position with the engine off.
You may not be able to start the
vehicle if the battery is allowed
to drain for an extended period
of time.
D (START):This position starts the
engine. When the engine starts,
release the key. The ignition switch
will return to ON/RUN for normal
driving.
A warning tone will sound when the
driver door is opened when the
ignition is still in ACC/ACCESSORY
and the key is in the ignition.Retained Accessory
Power (RAP)
These vehicle accessories may be
used for up to 10 minutes after
the engine is turned off:
Audio System
Power Windows
The power windows will continue to
work for up to 10 minutes or until
any door is opened. The radio
will work when the key is in ON/RUN
or ACC/ACCESSORY. Once the
key is turned from ON/RUN to
LOCK/OFF, the radio will continue
to work for 10 minutes or until
the driver door is opened.
Driving and Operating 8-3

Starting the Engine
Place the transmission in the
proper gear.
Automatic Transmission
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart
the vehicle when it is already
moving, use N (Neutral) only.
Notice:Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage
the transmission. Shift to P (Park)
only when the vehicle is stopped.
Manual Transmission
The shift lever should be in Neutral
and the parking brake engaged.
Hold the clutch pedal down to
the oor and start the engine. The
vehicle will not start if the clutch
pedal is not all the way down.Starting Procedure
1. With your foot off the accelerator
pedal, turn the ignition key to
START. When the engine starts,
let go of the key. The idle speed
will go down as the engine
warms. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently to allow the
oil to warm up and lubricate all
moving parts.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking for a
few seconds or until the vehicle
starts. If the engine does not start
and the key is held in START for
many seconds, cranking will be
stopped after 15 secondsto prevent cranking motor
damage. To prevent gear
damage, this system also
prevents cranking if the engine is
already running. Engine cranking
can be stopped by turning the
ignition switch to ACC/
ACCESSORY or LOCK/OFF.
Notice:Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after
5-10 seconds, especially in
very cold weather (below 0°F
or−18°C), it could be ooded with
too much gasoline. Push the
accelerator pedal all the way to
the oor and holding it there as
you hold the key in START for
a maximum of 15 seconds.
8-4 Driving and Operating

Wait at least 15 seconds between
each try, to allow the cranking
motor to cool. When the engine
starts, let go of the key and
accelerator. If the vehicle starts
briey but then stops again,
repeat the procedure. This clears
the extra gasoline from the
engine. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Notice:The engine is designed
to work with the electronics
in the vehicle. If you add electrical
parts or accessories, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer/retailer. If you do not, the
engine might not perform
properly. Any resulting damage
would not be covered by the
vehicle warranty.Engine Coolant Heater
The engine coolant heater, if
available, can help in cold weather
conditions at or below 0°F (−18°C)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting your
vehicle. An internal thermostat in the
plug-end of the cord will prevent
engine coolant heater operation at
temperatures above 0°F (−18°C).
To Use The Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The electrical cord is located on
the driver side of the engine
compartment, behind the
air cleaner for V8 models.
The electrical cord is located
on the passenger side of
the engine compartment, behind
the engine compartment fuse
block for V6 models.3. Plug it into a normal, grounded
110-volt AC outlet.
{CAUTION
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a re. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4. Before starting the engine, be
sure to unplug and store the
cord as it was before to keep
it away from moving engine
parts. If you do not it could be
damaged.
Driving and Operating 8-5

The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.
Automatic Transmission
Operation
The shift lever is located on the
center console between the
front seats.
There are several different positions
for the shift lever. When the
position of the shift lever is changed,a message is shown in the Driver
Information Center (DIC). The
selected gear is magnied in the
DIC, and changes according to the
shift lever’s movement. There
are also messages for Sport Shift
Mode, Normal Shift Mode and Driver
Shift Control.
P (Park):This position locks the
rear wheels. It is the best position
to use when the engine is started
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
(Continued)
CAUTION (Continued)
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 8-12. If you are pulling a
trailer, seeTowing a Trailer on
page 9-89.
Make sure the shift lever is fully
in P (Park) before starting the
engine. The vehicle has an
automatic transmission shift lock
control system. Fully apply the brake
pedal rst and then press the shift
lever button before shifting from
P (Park) when the ignition key is in
ON/RUN or ACC/ACCESSORY.
If you cannot shift out of P (Park),

ease pressure on the shift lever and
push the shift lever all the way
into P (Park) while maintaining brake
application. Then press the shift
lever button and move the shift lever
into another gear. SeeShifting
Out of Park on page 8-13.
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.
At low vehicle speeds, R (Reverse)
can also be used 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 8-29for additional information.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.
{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. It provides the best fuel
economy. If more power is needed
for passing, and the vehicle is:
Going less than 35 mph
(55 km/h), push the accelerator
pedal about halfway down.
Going about 35 mph (55 km/h) or
more, push the accelerator all the
way down.
Downshifting the transmission in
slippery road conditions could result
in skidding, see Skidding under
Loss of Control on page 8-23
Notice:Spinning the tires or
holding the vehicle in one place
on a hill using only the
accelerator pedal may damage
the transmission. If you are stuck,
do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.
Driving and Operating 8-7

Sport Shift Mode
The automatic transmission has a
Sport Shift Mode. When you
are in the Sport Shift Mode the
vehicle will still shift automatically.
The transmission may remain
in a gear longer than it would in the
normal driving mode based on
braking, throttle input, and vehicle
lateral acceleration. To use this
feature, move the shift lever
over from D (Drive) to the right
quadrant. The Sport Shift message
in the DIC displays. If the shift
lever is not moved forward or
rearward, the vehicle remains in
sport mode.Performance Mode Lift Foot Mode
Within Sport Shift Mode there is a
further performance feature called
Performance Mode Lift Foot (PMLF)
Mode. The feature is activated
automatically when sports oriented
driving is detected, based on
cornering and on/off throttle
application. PMLF allows the
transmission to hold the current gear
instead of upshifting when the
throttle is lifted.
Driver Shift Control (DSC)
Notice:If you drive your vehicle
at high RPMs without upshifting
while using Active Select Mode,
you could damage the vehicle.
Always upshift when necessary
while using Active Select Mode.The automatic transmission has a
DSC mode that allows gear changes
similar to a manual transmission.
To use this feature:
1. Move the shift lever over from
D (Drive) to the right quadrant.
The Sport Shift message in
the DIC displays.
2. To enter the DSC mode, press
the shift lever forward to upshift
or rearward to downshift.
The Active Select On message
in the DIC will come on.
The DIC will indicate the requested
gear range when moving the
shift lever forward or rearward.
8-8 Driving and Operating

While using the DSC mode, the
vehicle has rmer shifting and
increased performance. This can be
used for sport driving or when
climbing or descending hills, to stay
in gear longer, or to down shift
for more power or engine braking.
The transmission will only allow the
driver to shift into gears appropriate
for the vehicle speed and engine
Revolutions Per Minute (RPM). The
transmission will not automatically
shift to the next lower gear if the
engine RPM is too high.
If shifting is prevented for any
reason, the currently selected gear
will ash multiple times, indicating
that the transmission has not
shifted gears.While in the DSC mode, the
transmission automatically
downshifts when the vehicle comes
to a stop.
When accelerating the vehicle from
a stop in snowy and icy conditions,
1st, 2nd or 3rd gear starts can
be selected from a standing start.
This is useful for gentle acceleration
on slippery surfaces.
To return to Normal Shift mode,
slide the shift lever over from
the right quadrant to the left into
D (Drive). A Normal Shift message
will be displayed in the DIC.
Normal Shift Mode is recommended
for normal or freeway driving, as
it provides optimum fuel economy.Powertrain Braking
For vehicles with a 6 speed
automatic transmission, there is
an additional feature known as
Powertrain Braking. When driving
on steep descents where frequent
braking is required, the vehicle
will automatically downshift to
provide engine braking assistance.
This feature also reduces brake
temperatures and wear.
Downshifting will only occur when
the driver’s foot is applied to
the brake. Active Select Mode can
be switched on to override the
feature and gain complete control of
shifts if desired.
