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. Driver Shift Control can
be switched on to override the
feature and gain complete control
of shifts if desired.
Parking Brake
To set the parking brake, pull up on
the parking brake handle. If the
ignition is in the ON/RUN position,
the brake system warning light
will come on. SeeBrake System
Warning Light on page 4-16.To release the parking brake:
1. Hold the brake pedal down.
2. Pull the parking brake handle up
until you can press the release
button.
3. Hold the release button in as you
move the brake handle all the
way down.
Notice:Driving with the parking
brake on can overheat the
brake system and cause
premature wear or damage to
brake system parts. Make
sure that the parking brake is
fully released and the brake
warning light is off before driving.
Driving with the park brake applied
will cause a warning chime to
sound and the Park Brake message
to appear in the DIC. The message
will remain on until:
the park brake is released
the vehicle comes to a stop.
If you are towing a trailer and you
are parking on a hill, seeTowing a
Trailer on page 9-85.

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.

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.

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

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 brie y display the
appropriate message and then
return to the trip computer display.
