2007 CHEVROLET OPTRA 5 brake

;(Parking Lamps):Turn the band to this
position to turn on the parking lamps, together
instrument panel lights, taillamps, and license
plate lamp.
OFF:Turn the band to this position to turn
all lamps off except the Daytime Running
Lamps (DRL).
Headlamps on Reminder
If you open the driver’s door with the ignition
turned to LOCK or ACC while leaving the lamps
on, you will hear a warning chime.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.The DRL system will make your low-beam
headlamps come on in daylight when the following
conditions are met:
•The ignition is on.
•The exterior lamp band is in OFF or in the
parking lamp position.
•The parking brake is released.
An indicator light will come on when the DRL are
on. SeeDaytime Running Lamps (DRL)
Indicator Light on page 176.
When the DRL system is on, the taillamps,
sidemarker lamps, parking lamps and instrument
panel lights will not be illuminated unless you
have turned the exterior lamps control to
the parking lamp or headlamp position.
The DRL system will turn off when one of the
following conditions are met:
•The ignition is off.
•The parking brakes are on.
•The high-beam headlamps are on.
•The low-beam headlamps are on.
•The flash-to-pass feature is used.
As with any vehicle, you should turn on the
regular headlamp system when you need it.

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.
This light should come
on briefly when you turn
the ignition to ON. If it
does not come on then,
have it fixed 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 fully release. 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 floor. It may take longer to
stop. If the light is still on, have the vehicle
towed for service. SeeTowing Your Vehicle on
page 241.
{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
If your vehicle has an
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. 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 168.
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.

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 249.
Braking
SeeBrake System Warning Light on page 168.
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.
210

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 249.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 briefly
when you start your
vehicle.
211

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, your computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.
212

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 firmly 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
first 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 211.
In many emergencies, steering can help you more
than even the very best braking.
