Brake System Warning
Light
Your vehicle’s hydraulic brake
system is divided into two parts. If
one part is not working, the
other part can still work and stop
you. For good braking, though, you
need both parts working well.
If the warning light comes on, there
is a brake problem. Have your
brake system inspected right away.If your vehicle has anti-lock brakes,
this light should come on when
you turn the key to START. If it does
not come on, have it xed so it
will be ready to warn you if there is
a problem.
When the ignition is on, the brake
system warning light will also
come on when you set your parking
brake. The light will stay on if
your parking brake does not release
fully. If it stays on after your
parking brake is fully released, it
means you have a brake problem.
If the light comes on and Brake
message comes on the Driver
Information Center (DIC), while you
are driving, pull off the road and
stop carefully. You may notice that
the pedal is harder to push or
the pedal may go closer to the oor.It may take longer to stop. If the
light is still on, have the vehicle
towed for service. SeeAntilock
Brake System (ABS) Warning Light
on page 4-17andTowing Your
Vehicle on page 9-84.
{CAUTION
Your brake system may not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to an
accident. If the light is still on
after you have pulled off the
road and stopped carefully,
have the vehicle towed for
service.
The Brake message will remain until
3(Trip/Fuel) or8(Enter) are
pressed, but the brake light will
remain until the problem is xed. See

Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light will come
on brie y, as a check, when
you start your vehicle.
If it does not, have your vehicle
serviced so that the light works
properly when it needs to.
If the light and a message in the
DIC stays on longer than a few
seconds after you start your engine,
or comes on and stays on while
you are driving, try resetting
the system. To reset the system:
1. If you are driving, pull over when
it is safe to do so.
2. Place the vehicle in PARK (P).
3. Turn off the ignition.
4. Then restart the engine.If the light remains on after resetting
the system or comes on again
while driving, your vehicle needs
service. If the ABS light is on,
but the regular brake system
warning light is not on, the antilock
brakes are not working properly,
but the regular brakes are still
functioning. Have your vehicle
serviced right away. If both brake
lights are on, you do not have
antilock brakes, and there’s a
problem with your regular brakes as
well. Have your vehicle towed for
service. SeeTowing Your Vehicle
on page 9-84.
The ABS Fault message will remain
until
3(Trip/Fuel) or8(Enter)
are pressed, but the warning
light will remain until the problem is
xed. SeeDIC Warnings and
Messages on page 4-27for more
information.
Engine Coolant
Temperature Gage
This gage shows the engine coolant
temperature. If the gage pointer
moves into the red area, the engine
is too hot. It means that the engine
has overheated. Pull off the road,
stop the vehicle, and turn off the
engine as soon as possible. See
Engine Overheating on page 9-16.

Tire Pressure Light
TPMS Light
This light comes on brie y when the
engine is started and provides
information about tire pressures and
the Tire Pressure Monitoring System.
When the Light is Solid
This light will also come on when
one or more of your tires are
signi cantly underin ated. A CHECK
TIRE PRESSURE DIC message
will accompany the light.
SeeDIC Warnings and Messages
on page 4-27for more information.Stop and check your tires as soon as
it is safe to do so. If underin ated,
in ate to the proper pressure. See
Tires on page 9-39for more
information.
When the Light Flashes First and
Then is Solid
This indicates that there may be a
problem with the Tire Pressure
Monitor System.
The light ashes for about a minute
and stays on solid for the
remainder of the ignition cycle. This
sequence will repeat with every
ignition cycle. SeeTire Pressure
Monitor System on page 9-49
andTire Pressure Monitor Operation
on page 9-51for more information.
Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It makes sure that
emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.
This light comes on brie y, as a
check to show it is working,
when the ignition is turned to
ON/RUN. If the light does not come
on, see your dealer/retailer.
If the light stays on it indicates that
there is an OBD II problem and
service is required.

Malfunctions often are indicated by
the system before any problem
is apparent. Heeding the light can
prevent more serious damage
to your vehicle. This system assists
your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your
vehicle with this light on, after
a while, the emission controls
might not work as well, your
vehicle’s fuel economy might not
be as good, and the engine
might not run as smoothly. This
could lead to costly repairs
that might not be covered by your
warranty.
Notice:Modi cations made to
the engine, transmission, exhaust,
intake, or fuel system of your
vehicle or the replacement of the
original tires with other than those
of the same Tire Performance
Criteria (TPC) can affect your
vehicle’s emission controls and
can cause this light to come on.
Modi cations to these systemscould lead to costly repairs not
covered by your warranty. This
could also result in a failure to
pass a required Emission
Inspection/Maintenance test.
SeeAccessories and
Modifications on page 9-3.
This light comes on during a
malfunction in one of two ways:
Light Flashing:A mis re condition
has been detected. A mis re
increases vehicle emissions and
could damage the emission control
system on your vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to your vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If you are towing a trailer, reduce
the amount of cargo being
hauled as soon as it is possible.If the light continues to ash, when
it is safe to do so, stop the
vehicle. Find a safe place to park
the vehicle. Turn the key off, wait at
least 10 seconds, and restart the
engine. If the light is still ashing,
follow the previous steps and
see your dealer/retailer for service
as soon as possible.
Light On Steady:An emission
control system malfunction has been
detected on your vehicle. Diagnosis
and service might be required.
You might be able to correct the
emission system malfunction
by considering the following:
Make sure the fuel cap is fully
installed. SeeFilling the Tank
on page 8-35. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel
to evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn
the light off.

Care of CDs
Sound quality can be reduced
because of CD quality, the method
of recording, the quality of the
music that has been recorded, and
the way the CD has been handled.
If the surface of a CD is soiled,
take a soft, lint free cloth or dampen
a clean, soft cloth in a mild,
neutral detergent solution mixed
with water, and clean it. Make sure
the wiping process starts from
the center to the edge.
Handle CDs carefully.
Do not touch the bottom side of
a CD while handling it; this
could damage the surface.
Pick up CDs by grasping the
outer edges or the edge of
the hole and the outer edge.
Store CDs in their original cases
or other protective cases and
away from direct sunlight
and dust.
Care of the CD Player
Notice:If a label is added to a CD,
or more than one CD is inserted
into the slot at a time, or an
attempt is made to play scratched
or damaged CDs, the CD player
could be damaged. While using
the CD player, use only CDs in
good condition without any label,
load one CD at a time, and keep
the CD player and the loading slot
free of foreign materials, liquids,
and debris.
Do not add any label to a CD, it
could get caught in the CD player.
If a CD is recorded on a personal
computer and a description label
is needed, label the top of the
recorded CD with a marking pen.

Starting and
Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not
need an elaborate break-in. But it
will perform better in the long
run if you follow these guidelines:
Do not drive at any one
constant speed, fast or slow,
for the rst 500 miles (805 km).
Do not make full-throttle
starts. Avoid downshifting to
brake or slow the vehicle.
During the rst 600 miles
(1 000 km), avoid using
more than moderate
acceleration in lower gears and
avoid vehicle speeds above
68 mph (110 km/h).
Between the rst 600 miles
(1 000 km) and 3,000 miles
(5 000 km), heavy acceleration
in lower gears can be used.
Vehicle speeds above 68 mph
(110 km/h) should be limited
to ve minutes per use.
Avoid making hard stops for the
rst 200 miles (322 km) or so.
During this time the new brake
linings are not yet broken in.
Hard stops with new linings can
mean premature wear and
earlier replacement. Follow this
breaking-in guideline every
time you get new brake linings.
Do not tow a trailer during
break-in. SeeTowing a Trailer
on page 9-85for the trailer
towing capabilities of your
vehicle and more information.
Following break-in, engine speed
and load can be gradually
increased.
Ignition Positions
The ignition switch has four different
positions.
Notice:Using a tool to force the
key from the ignition switch
could cause damage or break the
key. Use the correct key and
turn the key only with your hand.
Make sure the key is in all the
way. If none of this works,
then your vehicle needs service.
To shift out of P (Park), turn the
ignition to ON/RUN and apply
the brake pedal.
8-2 Driving and Operating
2008 - Pontiac G8 Owner Manual
Page 152 of 334
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.

When the engine starts, let go of
the key and accelerator. If the
vehicle starts brie y but then
stops again, do the same thing.
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.

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 8-27for additional information.N (Neutral):In this position, the
engine does not connect with
the wheels. To restart 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 from the vehicle.
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.
The transmission will shift down
to a lower gear and have
more power.
Downshifting the transmission in
slippery road conditions could result
in skidding, see Skidding under
Loss of Control on page 8-21.
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
