How OnStar Service Works
The OnStar system can record and
transmit vehicle information. This
information is automatically sent to
an OnStar Call Center when the
OnStar button is pressed, the
emergency button is pressed, or if
the airbags or AACN system deploy.
The vehicle information usually
includes your GPS location and, in
the event of a crash, additional
information regarding the accident
that the vehicle has been involved in
(e.g. the direction from which the
vehicle was hit). When the Virtual
Advisor feature of OnStar
Hands-Free Calling is used, the
vehicle also sends OnStar your GPS
location so that we can provide
services where you are located.
OnStar service cannot work unless
the vehicle is in a place where
OnStar has an agreement with a
wireless service provider for service
in that area. OnStar service also
cannot work unless you are in
a place where the wireless service
provider OnStar has hired forthat area has coverage, network
capacity and reception when
the service is needed, and
technology that is compatible with
the OnStar service. Not all services
are available everywhere,
particularly in remote or enclosed
areas, or at all times.
Location information about the
vehicle is only available if the GPS
satellite signals are available
and unobstructed.
The vehicle must have a working
electrical system (including adequate
battery power) for the OnStar
equipment to operate. There are
other problems OnStar cannot
control that may prevent OnStar from
providing OnStar service to you at
any particular time or place. Some
examples are damage to important
parts of the vehicle in an accident,
hills, tall buildings, tunnels, weather
or wireless phone network
congestion.Your Responsibility
Increase the volume of the radio if
you cannot hear the OnStar advisor.
If the light next to the OnStar
buttons is red, the system is not
functioning properly and should be
checked by your dealer/retailer.
If the light appears clear (no light is
appearing), the OnStar subscription
has expired. Press the blue
OnStar button to con rm that the
OnStar equipment is active.

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 your
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

Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart
when you are already moving, use
N (Neutral) only.
Notice:Do not try to shift to
P (Park) if your vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when your vehicle is stopped.
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 your
engine gets warm. 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 seconds
to 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.
Try pushing the accelerator
pedal all the way to the oor
and holding it there as you hold
the key in START for up to a
maximum of 15 seconds.
Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
8-4 Driving and Operating
2008 - Pontiac G8 Owner Manual

{CAUTION
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (carbon
monoxide) gas to get inside.
CO could overcome you and
kill you. You cannot see it or
smell it, so you might not know
it is in your vehicle. Clear away
snow from around the base of
your vehicle, especially any
that is blocking the exhaust
pipe. And check around again
from time to time to be sure
snow does not collect there.
Open a window just a little on
the side of the vehicle that is
away from the wind. This will
help keep CO out.Run your engine only as long as you
must. This saves fuel. When you run
the engine, make it go a little faster
than just idle. That is, push the
accelerator slightly. This uses less
fuel for the heat that you get and it
keeps the battery charged. You will
need a well-charged battery to
restart the vehicle, and possibly
for signaling later on with the
headlamps. Let the heater run
for a while.
Then, shut the engine off and close
the window almost all the way to
preserve the heat. Start the engine
again and repeat this only when you
feel really uncomfortable from the
cold. But do it as little as possible.
Preserve the fuel as long as you can.
To help keep warm, you can get out
of the vehicle and do some fairly
vigorous exercises every half hour or
so until help comes.
If Your Vehicle is Stuck
in Sand, Mud, Ice,
or Snow
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
SeeRocking Your Vehicle to Get It
Out on page 8-28.
{CAUTION
If you let your vehicle’s tires
spin at high speed, they can
explode, and you or others
could be injured. The vehicle
can overheat, causing an
engine compartment re or
other damage. Spin the wheels
as little as possible and avoid
going above 35 mph (55 km/h)
as shown on the speedometer.

chains on the vehicle, seeTire
Chains on page 9-62.
