2010 PONTIAC G6 brakes

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 first 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.
Manual Shift Mode (MSM) (If Equipped)
To use this feature,
1. Move the shift lever from D (Drive) rearward into
the M (Manual Mode).
While driving in manual mode, the transmission will
remain in the driver selected gear.
2. Press the shift lever forward to upshift or rearward
to downshift.
3-26

SET−(Set):Press this button to set a speed and to
decrease the speed.
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 5-6. 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 40 km/h) (25 mph) or more, press
the RES+ symbol briefly.
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 briefly and then
release it. Each time this is done, the vehicle
goes about 1.6 km/h (1 mph) faster.
4-8

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 briefly. Each time this is done,
the vehicle goes about 1.6 km/h (1 mph) 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 find this to be too much trouble
and do not use cruise control on steep hills.
Ending Cruise Control
There are two ways to disengage the cruise control:
•Step lightly on the brake pedal.
•Press the on/off 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.

When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The
light will stay on if the parking brake does not fully
release. If it stays on after the parking brake is fully
released, it means there is a brake problem.
{WARNING:
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 floor. 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 5-23.
Antilock Brake System (ABS)
Warning Light
The Antilock Brake
System (ABS) light comes
on briefly 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 4-30.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 4-42for all
brake related DIC messages.
4-31

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 5-6and
Electronic Stability Control (ESC) on page 5-5.
Adding non-dealer/non-retailer accessories can affect
vehicle performance. SeeAccessories and Modications
on page 6-4.
Braking
SeeBrake System Warning Light on page 4-30.
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 100 km/h (60 mph) travels
20 m (66 feet). 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.
5-3

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 Modications
on page 6-4.Antilock Brake System (ABS)
This vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that helps 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 4-31.
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.
5-4

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 firmly 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.
Electronic Stability Control (ESC)
The vehicle has an Electronic Stability Control system
called StabiliTrak 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 light comes on when
StabiliTrak is activated.
When you first 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.
5-5

This light comes on if there
is a problem with the
system or 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.
The Traction Control System (TCS) and StabiliTrak
can be turned off if needed by pressing and holding
the TCS/ESC button until the StabiliTrak/TCS Off light
comes on. Press the button again to turn StabiliTrak and
Traction Control back on. See Traction Control System
(TCS) following for more information.
If cruise control is being used when the system
activates, cruise control will automatically disengage.
Press the cruise control button to reengage when road
conditions allow. SeeCruise Control on page 4-7for
more information.Traction Control System (TCS)
The vehicle has 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.
The system may be heard or felt while it is working, but
this is normal.
If cruise control is being used when TCS begins to
limit wheel spin, the cruise control will automatically
disengage. Press the cruise control button to reengage
when road conditions allow. SeeCruise Control on
page 4-7for more information.
TCS 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 that
is chosen, so use the lower gears only when necessary.
SeeAutomatic Transmission Operation on page 3-24.
