brakes PONTIAC VIBE 2007 Owners Manual

Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your
regular brakes rst and then press the shift lever
button before you can shift from PARK (P)
when the ignition key is in ON. If you cannot shift
out of PARK (P), ease pressure on the shift
lever, push the shift lever all the way into
PARK (P) and release the shift lever button as you
maintain brake application. Then press the shift
lever button and move the shift lever into the gear
you wish. SeeShifting Out of Park (P) (Automatic
Transaxle) on page 117.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage
the transaxle. The repairs would not be
covered by your warranty. Shift to
REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of
snow, ice or sand without damaging your
transaxle, seeIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 252.NEUTRAL (N):In this position, your engine does
not connect with the wheels. To restart when
you are already moving, use NEUTRAL (N) only.
{CAUTION:
Shifting into a drive gear while your
engine is running at high speed is
dangerous. Unless your foot is rmly on
the brake pedal, your vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while your engine is running at
high speed.
Notice:Shifting out of PARK (P) or
NEUTRAL (N) while the engine is running at
high speed may damage the transaxle.
The repairs would not be covered by your
warranty. Be sure the engine is not running at
high speeds when shifting your vehicle.
109

DRIVE (D):This position is for normal driving. It
provides the best fuel economy for your vehicle. If
you need more power for passing, and you are:
Going less than about 27 mph (43 km/h),
push your accelerator pedal about
halfway down.
Going about 29 mph (47 km/h) or more, push
your accelerator pedal all the way down. You
will shift down to the next gear and have
more power.
Downshifting the transaxle in slippery road
conditions could result in skidding, see
Skidding underLoss of Control on page 237.
SECOND (2):This position reduces vehicle speed
more than DRIVE (D) without using your brakes.
You can use SECOND (2) 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.LOW (L):This position reduces vehicle speed
even more than SECOND (2) without using your
brakes. You can use it on very steep hills, or
in deep snow or mud. If the shift lever is put in
LOW (L), the transaxle will not shift into low gear
until the vehicle is going slow enough.
Notice:Spinning the tires or holding the
vehicle in one place on a hill using only the
accelerator pedal may damage the transaxle. If
you are stuck, do not spin the tires. When
stopping on a hill, use the brakes, or parking
brake to hold the vehicle in place.

Shifting Out of Park (P)
(Automatic Transaxle)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your
regular brakes before you can shift from PARK (P)
when the ignition is in ON. SeeAutomatic
Transaxle Operation on page 108.
If you cannot shift out of PARK (P), ease pressure
on the shift lever – push the shift lever all the
way into PARK (P) and release the shift lever
button as you maintain brake application. Then
press the shift lever button and move the
shift lever into the gear you wish.
Shift Lock Release
If you ever hold the brake pedal down but still
cannot shift out of PARK (P), try this:
1. Turn the ignition to LOCK. Make sure the
parking brake is applied.2. Carefully pry the
cover from the shift
lock override,
located to the right
of the shift lever.
3. Insert the end of a at-tipped tool into the
round slot and press down rmly.
4. While maintaining brake application, move the
shift lever into the drive gear you want.
5. Have the vehicle xed as soon as possible.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good
braking, though, you need both parts working well.
If the warning light comes on, there is a brake
problem. Have your brake system inspected
right away.
If your vehicle has anti-lock brakes, this light
should come on when you turn the key to START.
If it does not come on then, have it xed so it
will be ready to warn you if there is a problem.When the ignition is on, the brake system warning
light will also come on when you set your
parking brake. The light will stay on if your parking
brake does not release fully. If it stays on after
your parking brake is fully released, it means you
have a brake problem.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice
that the pedal is harder to push or the pedal may
go closer to the oor. It may take longer to
stop. If the light is still on, have the vehicle towed
for service. SeeAnti-Lock Brake System
Warning Light on page 167andTowing Your
Vehicle on page 259.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.

Anti-Lock Brake System
Warning Light
With the Anti-Lock Brake System (ABS), this light
comes on when the engine is started and can
stay on for several seconds. This is normal.
If the light stays on, turn the ignition to LOCK. If
the light comes on while you are driving, 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
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 anti-lock
brakes. If the regular brake system warning light
is also on, you do not have anti-lock brakes
and there is a problem with the regular brakes.
SeeBrake System Warning Light on page 166.The ABS warning light comes on briey when you
turn the ignition key to ON. This 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.
Low Tire Pressure Warning Light
This light should come
on briey as you start
the engine.
It will then come on only when a low tire pressure
condition exists.
SeeTire Pressure Monitor System on page 330
for more information.

Control of a Vehicle
You have three systems that make your vehicle go
where you want it to go. They are the brakes, the
steering, and the accelerator. All three systems
have to do their work at the places where the tires
meet the road.
Sometimes, as when you are driving on snow or
ice, it is easy to ask more of those control systems
than the tires and road can provide. That means
you can lose control of your vehicle.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 272.
Braking
SeeBrake System Warning Light on page 166.
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.
226

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 may not have
time to cool between hard stops. The brakes
will wear out much 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 may 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 may take longer to stop and the brake pedal
will be harder to push.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 272.Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
If your vehicle has ABS, this warning light on the
instrument panel will come on briey when
you start your vehicle.
When you start your engine, or when you begin to
drive away, ABS will check itself. You may hear a
momentary motor or clicking noise while this test is
going on, and you may even notice that your brake
pedal moves or pulses a little. This is normal.
If there is a problem with ABS, the anti-lock brake
system warning light will stay on. SeeAnti-Lock
Brake System Warning Light on page 167.

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
front wheel and at both rear wheels.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, your computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.
228

If your vehicle has the vehicle stability control
system, it includes a brake assist system which
provides more powerful braking during a sudden,
hard brake application. See “Vehicle Stability
Control System” underTraction Control System
(TCS) on page 230.
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 your brakes 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 anti-lock work for you.
You may feel a slight brake pedal pulsation
or notice some noise, but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a
situation that requires hard braking.If you have ABS, you can steer and brake at the
same time. However, if you do not have ABS, your
rst reaction — to hit the brake pedal hard and hold
it down — may be the wrong thing to do. Your
wheels can stop rolling. Once they do, the vehicle
cannot respond to your 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 you were trying to avoid, or
into traffic.
If you do not have ABS, use a “squeeze” braking
technique. This will give you maximum braking
while maintaining steering control. You can 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 will help you retain
steering control. If you do have ABS, it is different.
SeeAnti-Lock Brake System (ABS) on page 227.
In many emergencies, steering can help you
more than even the very best braking.
229

Traction Control System (TCS)
Your vehicle may have a traction control system
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 works the front brakes and
reduces engine power to limit wheel spin.
You may feel or hear the system working, but this
is normal. Leave the system on during ordinary
driving so that it can operate when needed. When
the ignition is turned to ON, the system
automatically turns on.
This light should come
on briey when you
start the engine.
If it stays on or comes on while you are driving,
there is a problem with your traction control
system.The TRAC OFF button
is located to the left of
the steering wheel
below the instrument
panel cluster.
When getting the vehicle out of mud or newly
fallen snow, turn off the traction control system.
The system that controls engine performance
interferes with the process of freeing the
front wheels. To turn off traction control, press the
TRAC OFF button. The traction control system
warning light will come on. The vehicle stability
control system (StabiliTrak
®) is always activated,
even when the traction control system is turned
off. To turn the traction control system back
on, press the TRAC OFF button again. The
traction control system warning light will go off.
SeeTraction Control System (TCS) Warning Light
on page 168for more information.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 272for more information.
