2009 Pontiac G8 Owner ManualM

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 9-88.
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 4-26for 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 9-20.
Tire Pressure Light
TPMS Light
This light comes on briey when the
engine is started and provides
information about tire pressures and
the Tire Pressure Monitoring System.When the Light is On Steady
This light will also come on when
one or more of your tires are
signicantly underinated. A CHECK
TIRE PRESSURE DIC message
will accompany the light.
SeeDIC Warnings and Messages
on page 4-26for more information.
Stop and check your tires as soon
as it is safe to do so. If underinated,
inate to the proper pressure.
SeeTires on page 9-42for more
information.
When the Light Flashes First and
Then is On Steady
This indicates that there may be a
problem with the Tire Pressure
Monitor System.
The light ashes for about a minute
and stays on on steady for the
remainder of the ignition cycle.
This sequence will repeat with every
ignition cycle. SeeTire Pressure
Monitor System on page 9-52
andTire Pressure Monitor Operation
on page 9-54for more information.
Instruments and Controls 4-17

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 ensures
that emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.
This light comes on when the ignition
is on, but the engine is not running,
as a check to show it is working. If it
does not, have the vehicle serviced
by your dealer/retailer.If the check engine light comes on
and stays on, while the engine
is running, this indicates that there
is an OBD II problem and service
is required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage to
the vehicle. This system assists the
service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the 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 the vehicle warranty.Notice:Modications made to
the engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than those
of the same Tire Performance
Criteria (TPC) can affect the
vehicle’s emission controls and
can cause this light to come on.
Modications to these systems
could lead to costly repairs not
covered by the vehicle warranty.
This could also result in a failure
to pass a required Emission
Inspection/Maintenance test.

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

Alcohol affects four things that
anyone needs to drive a vehicle:
judgment, muscular coordination,
vision, and attentiveness.
Police records show that
almost 40 percent of all motor
vehicle-related deaths involve
alcohol. In most cases, these deaths
are the result of someone who
was drinking and driving. In recent
years, more than 17,000 annual
motor vehicle-related deaths have
been associated with the use of
alcohol, with about 250,000 people
injured.
For persons under 21, it is against
the law in every U.S. state to drink
alcohol. There are good medical,
psychological, and developmental
reasons for these laws.
The obvious way to eliminate the
leading highway safety problem
is for people never to drink alcohol
and then drive.Medical research shows that alcohol
in a person’s system can make crash
injuries worse, especially injuries to
the brain, spinal cord, or heart.
This means that when anyone who
has been drinking — driver or
passenger — is in a crash, that
person’s chance of being killed or
permanently disabled is higher than
if the person had not been drinking.
Control of a Vehicle
The following three systems help
to control your vehicle while
driving — brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of
your vehicle.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3.
Braking
SeeBrake System Warning Light on
page 4-15.
Braking action involves perception
time and reaction time. First,
you have to decide to push on the
brake pedal. That is perception time.
Then you have to bring up your
foot and do it. That is reaction time.
Average reaction time is about
three-fourths of a second. But that
is only an average. It might be
less with one driver and as long as
two or three seconds or more
with another. Age, physical
condition, alertness, coordination,
and eyesight all play a part. So
do alcohol, drugs, and frustration.
But even in three-fourths of a
second, a vehicle moving at 60 mph
(100 km/h) travels 66 feet (20 m).
That could be a lot of distance in an
emergency, so keeping enough
space between your vehicle
and others is important.
Driving and Operating 8-17

Steering
Power Steering
If you lose power steering assist
because the engine stops or the
system is not functioning, you can
steer but it will take much more effort.
Steering Tips
It is important to take curves at a
reasonable speed.
Traction in a curve depends on the
condition of the tires and the
road surface, the angle at which the
curve is banked, and your speed.
While in a curve, speed is the
one factor you can control.
If you need to reduce speed, do it
before you enter the curve, while the
front wheels are straight ahead.
Try to adjust the speed so you can
drive through the curve. Maintain
a reasonable, steady speed. Wait to
accelerate until you are out of the
curve, and then accelerate
gently into the straightaway.
Steering in Emergencies
There are times when steering can
be more effective than braking.
For example, you come over a hill
and nd a truck stopped in your
lane, or a car suddenly pulls
out from nowhere, or a child darts
out from between parked cars
and stops right in front of you.
You can avoid these problems by
braking — if you can stop in
time. But sometimes you cannot;
there is not room. That is the
time for evasive action — steering
around the problem.
Your vehicle can perform very well
in emergencies like these. First
apply the brakes. SeeBraking on
page 8-17. It is better to remove as
much speed as you can from a
possible collision. Then steer around
the problem, to the left or right
depending on the space available.An emergency like this requires
close attention and a quick decision.
If you are holding the steering wheel
at the recommended 9 and 3 o’clock
positions, you can turn it a full
180 degrees very quickly without
removing either hand. But you have
to act fast, steer quickly, and just as
quickly straighten the wheel once
you have avoided the object.
The fact that such emergency
situations are always possible is a
good reason to practice defensive
driving at all times and wear
safety belts properly.
8-22 Driving and Operating

Off-Road Recovery
Your vehicle’s right wheels can drop
off the edge of a road onto the
shoulder while driving.
If the level of the shoulder is only
slightly below the pavement,
recovery should be fairly easy. Ease
off the accelerator and then, if there
is nothing in the way, steer so that
your vehicle straddles the edge of
the pavement. Turn the steering
wheel 3 to 5 inches, 76 to 127 mm,
(about one-eighth turn) until the right
front tire contacts the pavement
edge. Then turn the steering wheel to
go straight down the roadway.
Passing
Passing another vehicle on a
two-lane road can be dangerous.
To reduce the risk of danger
while passing:
Look down the road, to the sides,
and to crossroads for situations
that might affect a successful
pass. If in doubt, wait.
Watch for traffic signs, pavement
markings, and lines that could
indicate a turn or an intersection.
Never cross a solid or
double-solid line on your side of
the lane.
Do not get too close to the
vehicle you want to pass. Doing
so can reduce your visibility.
Wait your turn to pass a slow
vehicle.
When you are being passed,
ease to the right.
Loss of Control
Let us review what driving experts
say about what happens when
the three control systems — brakes,
steering, and acceleration — do
not have enough friction where the
tires meet the road to do what
the driver has asked.
In any emergency, do not give up.
Keep trying to steer and constantly
seek an escape route or area of
less danger.
Skidding
In a skid, a driver can lose control
of the vehicle. Defensive drivers
avoid most skids by taking
reasonable care suited to existing
conditions, and by not overdriving
those conditions. But skids are
always possible.
The three types of skids correspond
to your vehicle’s three control
systems. In the braking skid,
the wheels are not rolling.
