2010 PONTIAC G3 brakes

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.
D4 (Automatic Overdrive) : This position is for normal
driving.
When operating the vehicle in severe cold conditions,
the transmission may be prevented from shifting into
D4 gear until the transmission fluid has warmed up to
it's operational temperature.
Notice: If the vehicle seems to start up rather
slowly or not shift gears when you go faster, and
you continue to drive the vehicle that way, you
could damage the transmission. Have the vehicle
serviced right away. You can drive in 2 (Second)
when you are driving less than 35 mph (55 km/h)
and D4 (Automatic Overdrive) for higher speeds
until then.
2 (Second) : This position gives you more power but
lower fuel economy. You can use 2 (Second) on hills.
It can help control vehicle speed as you go down steep
mountain roads, while using the brakes off and on. Notice:
Do not drive in 2 (Second) at speeds over
65 mph (105 km/h), or you can damage the
transmission. Use D4 (Automatic Overdrive) as
much as possible. Do not shift into 2 (Second)
unless you are going slower than 65 mph (105 km/h)
or you can damage the engine.
1 (First) : This position gives you even more power but
lower fuel economy than 2 (Second). You can use it on
very steep hills, or in deep snow or mud. If the shift
lever is put in 1 (First), the transmission will not shift into
first gear until the vehicle is going slowly enough.
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.
If there is a malfunction with the automatic transmission,
the malfunction indicator lamp (MIL) or the HOLD
indicator light will turn on or flash. See Malfunction
Indicator Lamp on page 4‑29.
Have the vehicle fixed as soon as possible.

Cruise Control
For vehicles with cruise control, a speed of about
39 km/h (24 mph) or more can be maintained without
keeping your foot on the accelerator. Cruise control
does not work at speeds below 39 km/h (24 mph).
When the brakes are applied, or the clutch pedal if you
have a manual transmission, the cruise control turns off.
{WARNING:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the cruise control on winding roads or in
heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire traction
can cause excessive wheel slip, and you could
lose control. Do not use cruise control on slippery
roads.
The cruise control buttons
are located on the right
side of the steering wheel.
I/O(On/Off) :Press to turn the cruise control on
or off.
RES+ (Resume/Accelerate) : Press to make the
vehicle accelerate or resume to a previously set speed.
SET− (Set/Coast) : Press to set the speed or make the
vehicle decelerate.

Setting Cruise Control
{WARNING:
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.
1. Press
I/Oto turn cruise control on.
2. Accelerate to the speed desired.
3. Press the SET− button and release it. The cruise
control light comes on in the instrument panel
cluster to show that the cruise control is on.
4. Take your foot off the accelerate pedal.
Resuming a Set Speed
If the cruise control is set to a desired speed and then
the brakes are applied, or the clutch pedal if you have a
manual transmission, the cruise control shuts off. But it
does not need to be reset. Once the vehicle is going about 39 km/h (24 mph) or
more, briefly press the RES+ button. The vehicle
returns to the previously set speed and stays there.
If the RES+ button is held, the vehicle speed will
continue to increase until the button is released or the
brake pedal is applied. Do not hold in the RES+ button,
unless you want the vehicle to go faster.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed.
.Use the accelerator pedal to get to a higher speed.
Press the SET−
button, then release the button
and the accelerator pedal.
.Press the RES+ button. Hold it there until the
desired speed is reached, and then release it.
To increase the vehicle speed in small amounts,
briefly press the RES+ button and then release it.
Each time this is done, the vehicle goes about
1.6 km/h (1 mph) faster.
The accelerate feature only works after the cruise
control is turned on by pressing the SET− button.
4-9

Reducing Speed While Using Cruise
Control
There are two ways to reduce the vehicle speed while
using cruise control:
.Press the SET−button until the lower speed
desired is reached, then release it.
.To slow down in small amounts, briefly press the
SET− button. 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 slows 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 the vehicle's speed.
When going downhill, you might have to brake or shift
to a lower gear to keep the vehicle's speed down.
When the brakes are applied the cruise control turns off.
Ending Cruise Control
There are two ways to turn off the cruise control:
.Step lightly on the brake pedal, or press the clutch
pedal, if you have a manual transmission.
.PressI/Oon the cruise control pad.
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
will also come 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.
If the light comes on while driving, carefully pull off the
road and stop. The pedal may be harder to push or may
go closer to the floor. It may take longer to stop. If the
light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 5‑25.
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 the light stays on, turn the ignition to LOCK/OFF or if
the light comes on, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again while driving, the vehicle needs service. See your
dealer/retailer. If the regular brake system warning light
is not on, the brakes will still work, but the antilock
brakes will not work. If the regular brake system
warning light is also on, the antilock brakes will not
work and there is a problem with the regular brakes.
See
Brake System Warning Light on page 4‑26.
The ABS warning light will come on briefly when the
ignition is turned to ON/RUN. This is normal. If the light
does not come on then, have it fixed so it will be ready
to warn if there is a problem.
Hold Mode Light
If the vehicle has this
feature, this light comes
on when the hold mode
is active.
If the HOLD mode light flashes, have the vehicle
checked. See “Hold Mode”underAutomatic
Transmission Operation
on page 3‑22for 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.
Adding non‐dealer/non‐retailer accessories can affect
vehicle performance. See Accessories and
Modifications 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.
5-3

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 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 comes
on briefly when the
vehicle is started.
The warning light is on the instrument panel cluster.
See Antilock Brake System (ABS) Warning Light
on
page 4‑27.
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.
5-4

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 might be heard,
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.
See Antilock Brake System (ABS) on page 5‑4.
In many emergencies, steering can help more than
even the very best braking.
Steering
Power Steering
If power steering assist is lost because the engine stops
or the system is not functioning, the vehicle can be
steered but it will take more effort.
Steering Tips
It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and vehicle speed. While in a curve, speed is
the one factor that can be controlled.
