2010 PONTIAC G5 brakes

{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park (Automatic Transmission) on page 3-30 .If
you are pulling a trailer, see Towing a Trailer
(Automatic Transmission) on page 5-33 orTowing
a Trailer (Manual Transmission) on page 5-39 .Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to fully
apply the regular brakes first and then press the shift
lever button before the vehicle can shift from P (Park)
when the ignition key is in ON/RUN. If the vehicle cannot
shift out of P (Park), ease pressure on the shift lever
and push the shift lever all the way into P (Park) as you
maintain brake application. Then press the shift lever
button and then move the shift lever into another gear.
See
Shifting Out of Park (Automatic Transmission)
on page 3-31.
Notice: Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
R (Reverse): Use this gear to back up.
To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission,
see If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 5-23.
3-25

N (Neutral):In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice: Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle. D (Drive):
This position is for normal driving with the
automatic transmission. It provides the best fuel
economy. If you need more power for passing and
you are:
•Going less than about 35 mph (55 km/h), push the
accelerator pedal about halfway down.
•Going about 35 mph (55 km/h), push the accelerator
all the way down.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” under Loss of
Control on page 5-15 .
I (Intermediate): This position is also used for normal
driving. However, it reduces vehicle speed without using
the brakes for slight downgrades where the vehicle
would otherwise accelerate due to steepness of grade.
If constant upshifting or downshifting occurs while
driving up steep hills, this position can be used to
prevent repetitive types of shifts. You might choose
I (Intermediate) instead of D (Drive) when driving
on hilly, winding roads and when towing a trailer, so that
there is less shifting between gears.
L (Low): This position reduces vehicle speed more
than I (Intermediate) without actually using the brakes.
You can use it on very steep hills, or in deep snow
or mud. If the shift lever is put in L (Low), the
transmission will not shift into a low gear until the
vehicle is going slowly enough.
3-26

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.
Manual Transmission Operation
This is the shift pattern.
Here is how to operate the manual transmission:
1 (First): Press the clutch pedal and shift into 1 (First).
Then, slowly let up on the clutch pedal as you press
the accelerator pedal.
You can shift into 1 (First) when the vehicle is traveling
less than 20 mph (32 km/h). If you have come to a
complete stop and it is hard to shift into 1 (First), put the shift lever in N (Neutral) and let up on the clutch pedal.
Press the clutch pedal back down. Then shift into
1 (First).
2 (Second):
Press the clutch pedal as you let up on the
accelerator pedal and shift into 2 (Second). Then,
slowly let up on the clutch pedal as you press the
accelerator pedal.
3 (Third), 4 (Fourth) and 5 (Fifth): Shift into 3 (Third),
4 (Fourth) and 5 (Fifth) the same way you do for
2 (Second). Slowly let up on the clutch pedal as you
press the accelerator pedal down.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press the
clutch pedal and the brake pedal, and shift to N (Neutral).
N (Neutral): Use this position when you start or idle the
engine.
R (Reverse): To back up, press down the clutch pedal
and shift into R (Reverse).
Notice: Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission. The
repairs would not be covered by the vehicle warranty.
Shift to R (Reverse) only after the vehicle is stopped.
Also, use R (Reverse), along with the parking brake, for
parking the vehicle.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this 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. See Brake System Warning Light on
page 4-26.
For vehicles with a Driver Information Center (DIC),
see DIC Warnings and Messages on page 4-38 for all
brake related DIC messages.
Enhanced Traction System (ETS)
Indicator/Warning Light
For vehicles with the
Enhanced Traction
System (ETS), this light
serves as an indicator
and warning light.
This light comes on briefly while 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 indicator/warning light is on and not flashing, the
ETS system could have been disabled. Check all related
Driver Information Center (DIC) messages to determine
whether the system has been turned off or if the system
is not working properly and the vehicle requires service.
If the ETS has been disabled, wheel spin is not limited.
If the indicator/warning light is on and flashing, the ETS
is actively working. The LOW TRACTION DIC message
also appears when the system is actively limiting
wheel spin.
See Enhanced Traction System (ETS) on page 5-11
and DIC Warnings and Messages on page 4-38 for
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 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.See
Traction Control System (TCS) on page 5-8 ,
Enhanced Traction System (ETS) on page 5-11 , and
Electronic Stability Control (ESC) on page 5-6 .
Adding non-dealer/non-retailer accessories can affect
vehicle performance. See Accessories and Modications
on page 6-3.
Braking
See Brake System Warning Light on page 4-26 .
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. 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 6-3.Antilock Brake System (ABS)
The vehicle might have the Antilock Brake System
(ABS), an advanced electronic braking system that helps
prevent a braking skid.
If the vehicle has ABS,
this warning light on the
instrument panel comes on
briefly when the vehicle is
started.
When the engine is started, or when 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 or pulses a little. This is normal.
5-4

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 firmly and let antilock work. A slight brake pedal
pulsation might be felt or some noise noticed, but this is
normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If the vehicle has ABS, it allows the driver to steer and
brake at the same time. However, if the vehicle does not
have ABS, the first reaction — to hit the brake pedal hard
and hold it down — might be the wrong thing to do. The
wheels can stop rolling. Once they do, the vehicle cannot
respond to the driver’s steering. Momentum will carry it in
whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the very
thing the driver was trying to avoid, or into traffic.
If the vehicle does not have ABS, use a “squeeze”
braking technique. This gives maximum braking while
maintaining steering control. Do this by pushing on
the brake pedal with steadily increasing pressure.
In an emergency, you will probably want to squeeze the
brakes hard without locking the wheels. If you hear or
feel the wheels sliding, ease off the brake pedal.
This helps retain steering control. With ABS, it is
different. SeeAntilock Brake System (ABS) on page 5-4 .
In many emergencies, steering can help more than
even the very best braking.
5-5

Electronic Stability Control (ESC)
The vehicle may have an Electronic Stability Control
(ESC) system which combines antilock brake, and
traction and stability control systems that help the driver
maintain directional control of the vehicle in most
driving conditions.
When the vehicle is started and begins to move, 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. The system
should initialize before the vehicle reaches 20 mph
(32 km/h).
If the system fails to turn on or activate, the ESC/TCS
light comes on, and the ESC OFF and/or SERVICE ESC
message displays.
For more information, seeDriver Information Center
(DIC) on page 4-35 andElectronic Stability Control
(ESC)/Traction Control System (TCS) Indicator/Warning
Light on page 4-28. This light flashes on the
instrument panel cluster
when the ESC system
is on and activated.
ESC activates when the computer senses a discrepancy
between the intended path and the direction the vehicle
is actually travelling. ESC selectively applies braking
pressure at any one of the vehicle’s brakes to help steer
the vehicle in the direction which you are steering.
When the system activates, an ESC ACTIVE message
displays on the Driver Information Center. See DIC
Warnings and Messages on page 4-38 . This light also
flashes on the instrument panel cluster when the
ESC system is on and activated. A noise may be heard
or a vibration felt in the brake pedal. This is normal.
Continue to steer the vehicle in the intended direction.
