2009 PONTIAC G6 brakes

Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-11.
Notice:If your vehicle seems to accelerate slowly
or not shift gears when you go faster, and you
continue to drive your vehicle that way, you could
damage the transmission. Have your vehicle serviced
right away. You can drive in L (Low) when you are
driving less than 35 mph (56 km/h) and D (Drive)
for higher speeds until then.
3 (Third):This position is also used for normal driving.
However, it reduces vehicle speed more than D (Drive)
without using the brakes. Here are some times you
might choose 3 (Third) instead of D (Drive):
When driving on hilly, winding roads.
When towing a trailer, so there is less shifting
between gears.
When going down a steep hill.
L (Low):This position reduces vehicle speed more
than 3 (Third) without using the brakes. You can
use L (Low) on hills. It can help control vehicle speed
going down steep mountain roads along with using
the brakes off and on.You can use L (Low) on very steep hills, in deep snow
or mud. If the shift lever is in L (Low), 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 the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
M (Manual Mode):This position allows you to change
gears similar to a manual transmission. If the vehicle
has this feature, see Manual Shift Mode (MSM)
following.
2-28

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 4-7. When road conditions allow, the
cruise control can be used again.
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.
3-11

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’sspeed. 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.
Ending Cruise Control
There are three ways to disengage the cruise control:
Step lightly on the brake pedal.
Press the on/off button.
Press the cancel button.
The cruise symbol in the instrument panel cluster turns
off when the system is disengaged.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.

{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
If the light comes on while driving, pull off the road and
stop carefully. The pedal can be harder to push, or
the pedal could go closer to the oor. It could take
longer to stop. Try turning off and restarting the vehicle
one or two times, if the light is still on, have the
vehicle towed for service. SeeTowing Your Vehicle on
page 4-26.
Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey when the engine
is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while 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 stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is not
on, the vehicle still has brakes, but not antilock brakes.
If the regular brake system warning light is also on,
the vehicle does not have antilock brakes and there is a
problem with the regular brakes. SeeBrake System
Warning Light on page 3-34.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-46for all
brake related DIC messages.

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.
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 the 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
the vehicle. SeeTraction Control System (TCS) on
page 4-7andStabiliTrak
®System on page 4-6.
Adding non-dealer/non-retailer accessories can affect
vehicle 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. Deciding to push the brake pedal is perception
time. Actually doing it 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
the 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 with a lot of heavy braking. Keeping pace with
the traffic and allowing realistic following distances
eliminates a lot of unnecessary braking. That means
better braking and longer brake life.
If the engine ever stops while the vehicle is being
driven, brake normally but do not pump the brakes.
If the brakes are pumped, the pedal could get harder
to push down. If the engine stops, there will still be some
power brake assist but it will be used when the brake
is applied. 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
vehicle performance. SeeAccessories and Modifications
on page 5-4.

Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS),
an advanced electronic braking system that will
help prevent a braking skid.
When the engine is started and the vehicle begins to
drive away, ABS checks itself. A momentary motor
or clicking noise might be heard while this test is going
on, and it might even be noticed that the brake pedal
moves a little. This is normal.
If there is a problem with
ABS, this warning light
stays on. SeeAntilock
Brake System (ABS)
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 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
the driver steer around the obstacle while braking hard.
As the brakes are applied, the computer keeps
receiving updates on wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the time needed to get
a foot up to the brake pedal or always decrease stopping
distance. If you get too close to the vehicle in front of you,
there will not be enough time to apply the brakes if that
vehicle suddenly slows or stops. Always leave enough
room up ahead to stop, even with ABS.

Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work. The antilock pump or
motor might be heard operating and the brake pedal
might be felt to pulsate, but this is normal.
Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more than
even the very best braking.
StabiliTrak®System
The vehicle may have the StabiliTrak system which
combines antilock brake, traction and stability control
systems and helps the driver maintain directional control
of the vehicle in most driving conditions.
StabiliTrak activates when the computer senses a
discrepancy between the 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 intended direction.This symbol will appear
when the StabiliTrak
system is activated.
When you rst start the vehicle and begin to drive away,
the system performs several diagnostic checks to ensure
there are no problems. The system may be heard or felt
while it is working. This is normal and does not mean
there is a problem with the vehicle.
This light is located on the
instrument panel cluster.
When the system is on, this light will come on if there
is a problem, or if the system has been turned off.
StabiliTrak comes on automatically whenever the
vehicle is started. To help assist with directional control
of the vehicle, the system should always be left on.
