2008 PONTIAC G6 brakes

THIRD (3):This position, available on the SE model, is
also used for normal driving. However, it reduces
vehicle speed more than DRIVE (D) without using your
brakes. Here are some times you might choose
THIRD (3) instead of DRIVE (D):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
LOW (L):This position, available on the SE model,
reduces vehicle speed more than THIRD (3) without
using your brakes. You can use LOW (L) on hills. It can
help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.
You can use LOW (L) on very steep hills, or in deep
snow or mud. If the shift lever is put in LOW (L),
the transmission will not shift into rst gear until the
vehicle is going slowly enough.
Notice:Driving in LOW (L) for more than 25 miles
(40 km) or at speeds over 55 mph (90 km/h) may
damage the transmission. Also, shifting into
LOW (L) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or DRIVE (D)
instead of LOW (L).Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
MANUAL MODE (M):This position, available on the
GT/GXP models, allows you to change gears similar to a
manual transmission. If your vehicle has this feature,
see Manual Shift Mode (MSM) following.
Manual Shift Mode (MSM) (Automatic
Transmission)
To use this feature, do the following:
1. Move the shift lever from DRIVE (D) rearward and
then to the right into the MANUAL MODE (M).
While driving in manual shift mode, the transmission
will remain in the driver gear selected.
2. Press the shift level forward to upshift or rearward
to downshift.
The odometer display on the instrument panel cluster
will change from the vehicle’s mileage to the letter M, for
manual shift mode, and a number indicating the
requested gear range when moving the shift lever
forward or rearward. SeeSpeedometer and Odometer
on page 3-29for more information.

Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
The cruise control buttons
are located on the steering
wheel.
J(On/Off):Press this button to turn the cruise
control system on and off.RES+ (Resume):Press this button to resume a set
speed and to accelerate the speed.
SET−(Set):Press this button to set a speed and to
decrease the speed.
[(Cancel):Press this button to cancel cruise control.
To set a speed do the following:
1. Press the on/off symbol to turn cruise control on.
The indicator light on the button comes on.
2. Get to the speed you want.
3. Press the SET−symbol and release it. The cruise
symbol displays in the instrument panel cluster to
show the system is engaged.
4. Take your foot off the accelerator pedal.
When the brakes are applied, the cruise control
shuts off.
If the vehicle is in cruise control and the Traction
Control System (TCS) or Enhanced Traction System
(ETS) begins to limit wheel spin, the cruise control
automatically disengages. SeeTraction Control System
(TCS) on page 4-5. When road conditions allow, the
cruise control can be used again.
3-11

Resuming a Set Speed
Suppose the cruise control is set at a desired speed
and the brakes are applied. This disengages the cruise
control. The cruise symbol in the instrument panel
cluster also goes out, indicating cruise is no longer
engaged. To return to the previously set speed, you do
not need to go through the set process again. Once
at a speed of about 25 mph (40 km/h) or more, press the
RES+ symbol briey.
This takes the vehicle back up and maintains the
previously chosen speed.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed.
If the cruise control system is already engaged,
press the RES+ symbol. Hold it there until the
speed desired is reached and then release
the button.
To increase the vehicle speed in very small
amounts, press the RES+ symbol briey and then
release it. Each time this is done, the vehicle
goes about 1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
If the cruise control system is already engaged,
Push and hold the SET−symbol until the lower
speed desired is reached, then release it.
To slow down in very small amounts, push the
SET−symbol briey. Each time this is done,
the vehicle goes about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle speed.
When you take your foot off the pedal, the vehicle will
slow down to the cruise control speed set earlier.
Using Cruise Control on Hills
How well the cruise control works on hills depends upon
the vehicle speed, load, and the steepness of the
hills. When going up steep hills, you might have to step
on the accelerator pedal to maintain your vehicle’s
speed. When going downhill, you might have to brake
or shift to a lower gear to keep your vehicle’s speed
down. Applying the brakes does turn off the cruise
control. Many drivers nd this to be too much trouble
and do not use cruise control on steep hills.

Antilock Brake System Warning
Light
For vehicles with the
Antilock Brake System
(ABS), this light will come
on briey when you
start the engine.
That is normal. If the light does not come on then, have it
xed so it will be ready to warn you if there is a problem.
If the ABS light stays on, turn the ignition off, if the light
comes on when you are driving, stop as soon as it
is safely possible and turn the ignition off. Then start the
engine again to reset the system. If the ABS light still
stays on, or comes on again while you are driving, your
vehicle needs service. If the regular brake system
warning light is not on, you still have brakes, but you do
not have antilock brakes. If the regular brake system
warning light is also on, you do not have antilock brakes
and there is a problem with your regular brakes. See
Brake System Warning Light on page 3-34.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-46for all
brake related DIC messages.
Traction Control System (TCS)
Warning Light
If the traction control
warning light comes on
and stays on, there may be
a problem with the
traction control system.
SeeTraction Control System (TCS) on page 4-5for
more information.

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. SeeTraction Control System (TCS) on
page 4-5andStabiliTrak
®System on page 4-6.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-4.
Braking
SeeBrake System Warning Light on page 3-34.
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
4-3

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 5-4.
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 Warning
Light on page 3-35.
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 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
4-4

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.
Traction Control System (TCS)
Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system reduces engine power and may
also upshift the transmission to limit wheel spin.
Also, the traction control system activates the
appropriate corner brakes to gain even quicker control
to limit wheel spin.This light, located on the
instrument panel, will come
on when your Traction
Control System is limiting
wheel spin.
You may feel or hear the system working, but this is
normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. SeeCruise Control
on page 3-10.
The Traction Control System operates in all transmission
shift lever positions except park or neutral. But the
system can upshift the transmission only as high as the
shift lever position you’ve chosen, so you should use
the lower gears only when necessary. SeeAutomatic
Transmission Operation on page 2-27.
4-5

This light is located on the
instrument panel cluster.
When the system is on, this light will come on to let you
know if there’s a problem, or if the system has been
turned off.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Traction
Control System on. But you can turn the system off if
you prefer.
To turn the system on or off, press the traction control
button (TC) located under the climate controls. In
order to effectively “rock” the vehicle, you will need to
turn off TCS.
If you press the TC button once, the traction control
system will turn off and the traction control system
warning light will come on. The StabiliTrak
®system will
stay on. Press the TC button again to turn the system
back on. The traction control system warning light will go
off. If you press and hold the TC button, the StabiliTrak
®
system and the traction control system will turn off.
Press the TC button again to turn StabiliTrak®and the
traction control system back on. For more information,
seeStabiliTrak
®System on page 4-6.
When you turn the system off, the Traction Control
System warning light will come on and stay on. If the
Traction Control System is limiting wheel spin when you
press the button to turn the system off, the warning
light will come on and the system will stop limiting wheel
spin. The system will not provide traction assistance
until the system is turned back on.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-4for more information.
StabiliTrak®System
Your vehicle may be equipped with a vehicle stability
enhancement system called StabiliTrak®.Itisan
advanced computer controlled system that assists you
with directional control of the vehicle in difficult
driving conditions.
StabiliTrak
®activates when the computer senses a
discrepancy between your intended path and the
direction the vehicle is actually traveling. StabiliTrak
®
selectively applies braking pressure at any one of
the vehicle’s brakes to help steer the vehicle in the
direction which you are steering.
