2008 PONTIAC G8 Owners Manual

{CAUTION
It can be dangerous to get out
of your vehicle if the shift lever
is not fully in PARK (P) with the
parking brake rmly set. Your
vehicle can roll. Do not leave
your 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 your
vehicle will not move, even
when you are on fairly level
ground, always set the parking
brake and move the shift lever
to PARK (P).
Follow the proper steps to be sure
your vehicle will not move. See
Shifting Into Park (Automatic
Transmission) on page 8-10.
If you are parking on a hill and if
you are pulling a trailer, also
seeTowing a Trailer on page 9-85.
Driving Your Vehicle
Defensive Driving
Defensive driving means “always
expect the unexpected.” The
rst step in driving defensively is to
wear your safety belt, seeSafety
Belts on page 1-5.
{CAUTION
Assume that other road users
(pedestrians, bicyclists, and
other drivers) are going to be
careless and make mistakes.
Anticipate what they might do
and be ready. In addition:
Allow enough following
distance between you and
the driver in front of you.
Focus on the task of driving.
Driver distraction can cause
collisions resulting in injury or
possible death. These simple
defensive driving techniques
could save your life.
Drunk Driving
{CAUTION
Drinking and then driving is
very dangerous. Your reexes,
perceptions, attentiveness, and
judgment can be affected by
even a small amount of alcohol.
You can have a serious — or
even fatal — collision if you
drive after drinking. Do not
drink and drive or ride with a
driver who has been drinking.
Ride home in a cab; or if you
are with a group, designate a
driver who will not drink.
Death and injury associated with
drinking and driving is a global
tragedy.
Alcohol affects four things that
anyone needs to drive a vehicle:
judgment, muscular coordination,
vision, and attentiveness.
Driving and Operating 8-13
2008 - Pontiac G8 Owner Manual

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 4-16.
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.
8-14 Driving and Operating
2008 - Pontiac G8 Owner Manual

And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is
pavement or gravel; the condition of
the road, whether it is wet, dry, or
icy; tire tread; the condition of
the brakes; the weight of the
vehicle; and the amount of brake
force applied.
Avoid needless heavy braking.
Some people drive in
spurts — heavy acceleration
followed by heavy braking — rather
than keeping pace with traffic.
This is a mistake. The brakes might
not have time to cool between
hard stops. The brakes will wear out
much faster if you do a lot of heavy
braking. If you keep pace with
the traffic and allow realistic
following distances, you will
eliminate a lot of unnecessary
braking. That means better braking
and longer brake life.If your vehicle’s engine ever stops
while you are driving, brake normally
but do not pump the brakes.
If you do, the pedal could get harder
to push down. If the engine stops,
you will still have some power brake
assist. But you will use it when
you brake. Once the power assist is
used up, it can take longer to
stop and the brake pedal will be
harder to push.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3.Antilock Brake
System (ABS)
Your vehicle has the Antilock
Brake System (ABS), an advanced
electronic braking system that
will help prevent a braking skid.
When you start the engine and
begin to drive away, ABS will check
itself. You might hear a momentary
motor or clicking noise while this
test is going on, and you might even
notice that the brake pedal moves
a little. This is normal.
If there is a problem with ABS,
this warning light will stay on.
SeeAntilock Brake System (ABS)
Warning Light on page 4-17.
Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you.
Driving and Operating 8-15
2008 - Pontiac G8 Owner Manual

You slam on the brakes and
continue braking. Here is what
happens with ABS:
A computer senses that wheels
are slowing down. If one of
the wheels is about to stop rolling,
the computer will separately
work the brakes at each wheel.
ABS can change the brake pressure
faster than any driver could.
The computer is programmed to
make the most of available tire and
road conditions. This can help
you steer around the obstacle while
braking hard.
As you brake, the computer keeps
receiving updates on wheel speed
and controls braking pressure
accordingly.Remember: ABS does not change
the time you need to get your
foot up to the brake pedal or always
decrease stopping distance.
If you get too close to the vehicle in
front of you, you will not have
time to apply the brakes if that
vehicle suddenly slows or stops.
Always leave enough room up
ahead to stop, even though
you have ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down rmly and
let antilock work for you. You might
hear the antilock pump or motor
operate, and feel the brake
pedal pulsate, but this is normal.
Braking in Emergencies
With ABS, you can steer and
brake at the same time. In many
emergencies, steering can help
you more than even the very
best braking.
Electronic Stability
Program
The vehicle has the Electronic
Stability Program (ESP®) that
assists with directional control of the
vehicle in difficult driving conditions
by reducing engine power and
applying the brakes to individual
wheels. This is especially useful
in slippery road conditions.
The system operates if it senses
that the rear wheels are spinning
too much, are beginning to lose
traction or if it senses that the
vehicle is not moving in its intended
direction. It turns on automatically
every time the vehicle is started.
When ESP is working, this light
and the STABILITY CONTROL
ASSISTANCE message will come
8-16 Driving and Operating
2008 - Pontiac G8 Owner Manual

on and the ESP CTRL message
will be displayed at the bottom of
the DIC.
The STABILITY CONTROL
ASSISTANCE message will remain
on while the system is working
until the
3button is pressed to
display the trip computer. The ESP
CTRL message stays on at the
bottom of the DIC while the system
is working.
You may feel or hear the system
working, but this is normal.
When this light and the STABILITY
CTRL OFF message is on and
the ESP OFF message is displayed,
the system will not limit wheel spin.Adjust your driving accordingly.
SeeDIC Warnings and Messages
on page 4-27for more information.
ESP is automatically enabled
whenever you start your vehicle.
To limit wheel spin, especially
in slippery road conditions, you
should always leave the system
enabled. You can turn ESP off if you
ever need to.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if your
vehicle is stuck in sand, mud, ice or
snow, and you want to rock your
vehicle to attempt to free it. It may
also be necessary to turn off the
system when driving in extreme
off-road conditions where high
wheel spin is required. SeeIf Your
Vehicle is Stuck in Sand, Mud,
Ice, or Snow on page 8-27.The ESP button is located in front of
the transmission gear selector lever.
To turn the system off or on, press
and release the ESP button.
The DIC will briey display the
appropriate message and then
return to the trip computer display.
Driving and Operating 8-17
2008 - Pontiac G8 Owner Manual

When this light and the STABILITY
CTRL OFF message is on briey
and the ESP OFF message is
displayed at the bottom of the DIC,
the system will not limit wheel spin.
If the ESP OFF message is
always displayed at the bottom of
the DIC when the button is pressed
to turn the system on or off, the
system needs repair. Contact your
dealer/retailer.
The system is on when this light
and the STABILITY CTRL ON
message is displayed briey on
the DIC.
ESP Operation
ESP limits wheel spin by reducing
engine power to the wheels and
by applying brakes to each
individual wheel as necessary.
The ESP system is enabled
automatically when you start your
vehicle, and it will activate the
STABILITY CONTROL
ASSISTANCE light and the ESP
CTRL message on the DIC if
it senses that any of the wheels are
spinning or beginning to lose
traction while driving.
Notice:If you allow the wheel(s)
of one axle to spin excessively
while the ESC/TCS, ABS and
Brake warning lights and
the SERVICE ESC and/or
SERVICE TRACTION messages
are displayed, you could damagethe differential. The repairs would
not be covered by your warranty.
Reduce engine power and do
not spin the wheel(s) excessively
while these lights and this
message are displayed.
The traction control system may
activate on dry or rough roads
or under conditions such as heavy
acceleration while turning or
abrupt upshifts/downshifts of the
transmission. When this happens,
you may notice a reduction in
acceleration, or may hear a noise or
vibration. This is normal.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3for
more information.

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.
A lot of the “driver lost control”
accidents mentioned on the news
happen on curves. Here is why:
Experienced driver or beginner,
each of us is subject to the same
laws of physics when driving
on curves. The traction of the tires
against the road surface makes
it possible for the vehicle to change
its path when you turn the front
wheels. If there is no traction, inertia
will keep the vehicle going in thesame direction. If you have ever
tried to steer a vehicle on wet ice,
you will understand this.
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.
Suppose you are steering through
a sharp curve. Then you
suddenly accelerate. Both control
systems — steering and
acceleration — have to do their
work where the tires meet the road.
Adding the sudden acceleration
can demand too much of those
places. You can lose control.
What should you do if this ever
happens? Ease up on the
accelerator pedal, steer the vehicle
the way you want it to go, and
slow down.Speed limit signs near curves warn
that you should adjust your
speed. Of course, the posted
speeds are based on good weather
and road conditions. Under less
favorable conditions you will want to
go slower.
If you need to reduce speed when
approaching a curve, 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.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3.

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 8-14. 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.
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 (about
one-eighth turn) until the right front
tire contacts the pavement edge.
Then turn the steering wheel to go
straight down the roadway.
