brakes CHEVROLET AVEO 2007 1.G Owners Manual

Ensure that the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has
an automatic transaxle shift lock control system.
You have to apply your regular brakes before you
can shift from PARK (P) when the key is in ON.
If you cannot shift out of PARK (P) while holding
the brake pedal down, seeShifting Out of Park (P)
on page 120.
REVERSE (R):Use this gear to back up.
When shifting from NEUTRAL (N) to
REVERSE (R), you need to apply the regular
brake and push the release button on the front of
the shifter and then forward.
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 248.NEUTRAL (N):In this position, your engine does
not connect with the wheels. To restart while
you are already moving, use NEUTRAL (N) only.
Also, use NEUTRAL (N) when your vehicle is
being towed.
{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.
113

AUTOMATIC OVERDRIVE (D4):This position is
for normal driving.
When operating your vehicle in severe cold
conditions, the transaxle may be prevented from
shifting into D4 gear until the transaxle fluid
has warmed up to it’s operational temperature.
Notice:If your vehicle seems to start up rather
slowly or not shift gears when you go faster,
and you continue to drive your vehicle that
way, you could damage the transaxle.
Have your vehicle serviced right away. You
can drive in SECOND (2) when you are driving
less than 35 mph (55 km/h) and AUTOMATIC
OVERDRIVE (D4) for higher speeds until then.
SECOND (2):This position gives you more
power but lower fuel economy. 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.Notice:Do not drive in SECOND (2) at speeds
over 65 mph (105 km/h), or you can damage the
transaxle. Use AUTOMATIC OVERDRIVE (D4) as
much as possible. Do not shift into SECOND (2)
unless you are going slower than 65 mph
(105 km/h) or you can damage your engine.
FIRST (1):This position gives you even more
power but lower fuel economy than SECOND (2).
You can use it on very steep hills, or in deep
snow or mud. If the shift lever is put in FIRST (1),
the transaxle 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 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.
If there is a malfunction with the automatic
transaxle, the malfunction indicator lamp (MIL) or
the HOLD indicator light will turn on or flash.
SeeMalfunction Indicator Lamp on page 180or
Hold Mode Light on page 180.
Have your vehicle fixed as soon as possible.
114

Shifting Out of Park (P)
Your automatic transaxle 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 turned to
ON. SeeAutomatic Transaxle Operation on
page 112.
If you cannot shift out of PARK (P) while holding
the brake pedal down, try this:
1. Set the parking brake.
2. Turn the ignition off and remove the key.
3. Remove the cover over the shift-lock release
slot by prying it off using a small, flat object.
The shift-lock release slot is located at the top
of the shift lever.4. Insert the key into the shift-lock release slot
and press and hold the key.
5. Shift to NEUTRAL (N).
6. Remove the key from the shift-lock release
slot, insert the key into the ignition and start
the engine.
7. Replace the shift-lock release slot cover.
8. Apply and hold the regular brake fully
and release the parking brake.
9. Shift to the gear you want.
10. Have the system fixed as soon as you can.

Rear Window Wiper/Washer
(Hatchback)
{CAUTION:
In freezing weather, do not use your
washer until the windshield is warmed.
Otherwise the washer uid can form ice
on the windshield, blocking your vision.
Your vehicle may have a rear window
washer/wiper. Operate the rear window
washer/wiper system by pushing the windshield
washer/wiper lever away from you. The wiper
operates intermittently when the lever is in the first
position. Washer fluid sprays onto the rear
window and the wiper operates continuously when
the lever is pushed to the second position.
The rear window washer uses the same fluid
bottle as the windshield washer. However, the rear
window washer will run out of fluid before the
windshield washer. If you can wash your
windshield but not your rear window, check the
fluid level.
Cruise Control
If your vehicle has cruise control, you can maintain
a speed of about 24 mph (39 km/h) or more
without keeping your foot on the accelerator. This
can really help on long trips. Cruise control
does not work at speeds below 24 mph (39 km/h).
When you apply your brakes, or the clutch
pedal if you have a manual transaxle, the cruise
control turns off.
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your 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.
141

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 your regular
brakes. SeeBrake System Warning Light on
page 163.
The ABS warning light will come on briefly when
you turn the ignition to ON. This is normal. If
the light does not come on then, have it fixed so it
will be ready to warn you if there is a problem.
Hold Mode Light
If your vehicle has this
feature, this light will
come on when the hold
mode is active.
If the HOLD mode light flashes, have your vehicle
checked. See “Hold Mode” underAutomatic
Transaxle Operation on page 112for additional
information on this feature.

Charging System Light
The charging system
light will come on briefly
when you turn on the
ignition, and the engine
is not running, as a
check to show you it is
working.
Then it should go out when the engine is started.
If it stays on, or comes on while you are driving,
you may have a problem with the electrical
charging system. Have it checked by your dealer.
Driving while this light is on could drain your
battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and air conditioner.
Anti-Lock Brake System Warning
Light
Your vehicle may have
the Anti-Lock Brake
System (ABS).
This light will come on when the ignition is turned
to ON and may stay on for several seconds.
That is normal.
If the light stays on, turn the ignition to LOCK. 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 you are driving, your vehicle needs
service. See your dealer/retailer. 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 your regular brakes. SeeBrake System
Warning Light on page 163.

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
Modifications on page 264.
Braking
SeeBrake System Warning Light on page 163.
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.
224

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
Modifications on page 264.Anti-Lock Brake System (ABS)
Your vehicle might 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 will
come on briefly
when you start your
vehicle.
The warning light is on the instrument panel
cluster for a sedan. SeeAnti-Lock Brake System
Warning Light on page 179. For hatchback
models, the warning light is on the Secondary
Information Center (SIC). SeeAnti-Lock Brake
System Warning Light on page 179.

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
wheel.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, the computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.
226

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 the 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 firmly and let anti-lock work for you.
You might 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
first reaction — to hit the brake pedal hard and
hold it down — might 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 225.
In many emergencies, steering can help you more
than even the very best braking.
