2009 PONTIAC G8 change time

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 topush 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. See
Antilock Brake System (ABS)
Warning Light on page 4-16.
Let us say the road is wet and you
are driving safely. Suddenly, an
animal jumps out in front of you.
You slam on the brakes and continue
braking. Here is what happens
with ABS:
A computer senses that the 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
to each wheel, as required, faster
than any driver could. This can help
you steer around the obstacle while
braking hard.
8-18 Driving and Operating

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 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.
Driving and Operating 8-19

In the steering or cornering skid, too
much speed or steering in a curve
causes tires to slip and lose
cornering force. And in the
acceleration skid, too much throttle
causes the driving wheels to spin.
If your vehicle starts to slide, ease
your foot off the accelerator pedal
and quickly steer the way you want
the vehicle to go. If you start steering
quickly enough, your vehicle may
straighten out. Always be ready for a
second skid if it occurs.
Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
you want to slow down and
adjust your driving to these
conditions. It is important to slow
down on slippery surfaces because
stopping distance is longer and
vehicle control more limited.
While driving on a surface with
reduced traction, try your best to
avoid sudden steering, acceleration,
or braking, including reducing vehicle
speed by shifting to a lower gear.Any sudden changes could cause
the tires to slide. You might not
realize the surface is slippery until
your vehicle is skidding. Learn to
recognize warning clues — such as
enough water, ice, or packed snow
on the road to make a mirrored
surface — and slow down when you
have any doubt.
Remember: Any Antilock Brake
System (ABS) helps avoid only the
braking skid.
Driving at Night
Night driving is more dangerous
than day driving because some
drivers are likely to be impaired — by
alcohol or drugs, with night vision
problems, or by fatigue.
Night driving tips include:
Drive defensively.
Do not drink and drive.
Reduce headlamp glare by
adjusting the inside rearview
mirror.
Slow down and keep more space
between you and other vehicles
because headlamps can only
light up so much road ahead.
Watch for animals.
When tired, pull off the road.
Do not wear sunglasses.
Avoid staring directly into
approaching headlamps.
Keep the windshield and all glass
on your vehicle clean — inside
and out.
Keep your eyes moving,
especially during turns or curves.
No one can see as well at night as
in the daytime. But, as we get
older, these differences increase.
A 50-year-old driver might need
at least twice as much light to see
the same thing at night as a
20-year-old.
8-24 Driving and Operating

Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that lets you know when to change
the engine oil and lter. This is
based on engine revolutions and
engine temperature, and not
on mileage. Based on driving
conditions, the mileage at which an
oil change will be indicated can
vary considerably. For the oil
life system to work properly, you
must reset the system every
time the oil is changed.
When the system has calculated
that oil life has been diminished,
it will indicate that an oil change is
necessary. The Service Engine
Oil message will be displayed.Change the oil as soon as possible
within the next 600 miles (1 000 km).
It is possible that, if you are driving
under the best conditions, the oil life
system might not indicate that an oil
change is necessary for over a year.
However, the engine oil and lter
must be changed at least once a
year and at this time the system must
be reset. Your dealer/retailer has
trained service people who will
perform this work using genuine
parts and reset the system. It is also
important to check the oil regularly
and keep it at the proper level.
If the system is ever reset
accidentally, you must change
the oil at 3,000 miles (5 000 km)
since the last oil change. Remember
to reset the oil life system whenever
the oil is changed.
How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where you
change the oil prior to the Service
Engine Oil message being displayed,
reset the system.
After changing the engine oil, reset
the system:
1. Turn the ignition key to ON/RUN
with the engine off.
2. Fully press and release the
accelerator pedal three times
within ve seconds.
If the Service Engine Oil
message does not appear,
the system is reset.
If the Service Engine Oil message
displays, reset the system again.
9-10 Vehicle Service and Care

Notice:Continuing to drive with
worn-out brake pads could
result in costly brake repair.
Some driving conditions or climates
can cause a brake squeal when
the brakes are rst applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent
brake pulsation. When tires are
rotated, inspect brake pads for wear
and evenly tighten wheel nuts in
the proper sequence to torque
specications inCapacities and
Specifications on page 10-2.
Brake linings should always be
replaced as complete axle sets.Brake Pedal Travel
See your dealer/retailer if the brake
pedal does not return to normal
height, or if there is a rapid increase
in pedal travel. This could be a
sign that brake service might
be required.
Brake Adjustment
Every time he brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle
is complex. Its many parts have
to be of top quality and work
well together if the vehicle is
to have really good braking.The vehicle was designed and
tested with top-quality brake parts.
When parts of the braking system
are replaced — for example,
when the brake linings wear
down and new ones are
installed — be sure to get new
approved replacement parts. If this
is not done, the brakes might
not work properly. For example,
if someone puts in brake linings that
are wrong for the vehicle, the
balance between the front and rear
brakes can change — for the
worse. The braking performance
expected can change in many other
ways if the wrong replacement
brake parts are installed.

The TPMS operates on a radio
frequency and complies with
RSS-210 of Industry and Science
Canada. Operation is subject to the
following two conditions:
1. This device may not cause
interference.
2. This device must accept any
interference received, including
interference that may cause
undesired operation of the device.
Changes or modications to this
system by other than an authorized
service facility could void
authorization to use this equipment.Tire Pressure Monitor
Operation
The Tire Pressure Monitor System
(TPMS) is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and
wheel assembly, excluding the
spare tire and wheel assembly. The
TPMS sensors monitor the air
pressure in the vehicle’s tires and
transmit the tire pressure readings to
a receiver located in the vehicle.
When a low tire pressure condition
is detected, the TPMS turns on the
7
low tire pressure warning light.
At the same time a message to
check the pressure in a specic tire
appears on the Driver Information
Center (DIC) display. The low tire
pressure warning light and the DIC
warning message come on at each
ignition cycle until the tires are
inated to the correct ination
pressure. Using the DIC, tire
pressure levels can be viewed bythe driver. For additional information
and details about the DIC operation
and displays seeDIC Operation and
Displays on page 4-22andDIC
Warnings and Messages on
page 4-26.
The low tire pressure warning light
may come on in cool weather
when the vehicle is rst started, and
then turn off as you start to drive.
This could be an early indicator that
the air pressure in the tire(s) are
getting low and need to be inated
to the proper pressure.
A Tire and Loading Information label
shows the size of the vehicle’s
original equipment tires and the
correct ination pressure for the
vehicle’s tires when they are cold.
SeeLoading the Vehicle on
page 8-30, for an example of the Tire
and Loading Information label and its
location on the vehicle. Also see
Inflation - Tire Pressure on
page 9-49.
9-54 Vehicle Service and Care

Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.
SeeWhen It Is Time for New
Tires on page 9-59andWheel
Replacement on page 9-64.
When rotating the vehicle’s tires,
always use the correct rotation
pattern shown here.The compact spare tire, if the
vehicle has one, is not included
in the tire rotation.
After the tires have been rotated,
adjust the front and rear ination
pressures as shown on the Tire
and Loading Information label.
SeeInflation - Tire Pressure on
page 9-49andLoading the
Vehicle on page 8-30.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation on page 9-54.
Make certain that all wheel
nuts are properly tightened.
See “Wheel Nut Torque” under
Capacities and Specifications on
page 10-2.{CAUTION
Rust or dirt on a wheel, or on
the parts to which it is
fastened, can make wheel
nuts become loose after time.
The wheel could come off and
cause an accident. When you
change a wheel, remove any
rust or dirt from places where
the wheel attaches to the
vehicle. In an emergency, you
can use a cloth or a paper
towel to do this; but be sure to
use a scraper or wire brush
later, if needed, to get all the
rust or dirt off. SeeChanging
