Driving while this light is on could
drain your battery.
If you must drive a short distance
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
The Alternator message will remain
until
3(Trip/Fuel) or8(Enter)
are pressed, but the light will remain
until the problem is xed. See
DIC Warnings and Messages on
page 4-27for more information.
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
DIC Warnings and Messages on
page 4-27for more information. United States

Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light will come
on briey, 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.

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

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.
