2007 CHEVROLET OPTRA 5 headlamp

Fog Lamps
If your vehicle has fog lamps, use them for better
visibility in foggy or misty conditions.
The band for the front fog lamps is located in the
middle of the turn signal/multifunction lever.
While using the fog lamps, the ignition must be on
as well as the parking lamps or low-beam
headlamps.
Turn the band to ON to turn the fog lamps on. An
indicator light will come on while the fog lamps
are on. SeeFog Lamp Light on page 176.
Turn the band to OFF to turn the fog lamps off.
The fog lamps will also turn off while the
high-beam headlamps are turned on. When the
high-beam headlamps are turned off, the fog lamps
will turn on again.
Instrument Panel Brightness
The thumbwheel for
this feature is located
on the instrument panel
to the left of the
steering wheel.
Turn the thumbwheel up to brighten the instrument
panel lights or down to dim them.

While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road to
make a mirrored surface — and slow down when
you have any doubt.
If you have the Anti-Lock Brake System (ABS),
remember: It helps avoid only the braking
skid. If you do not have ABS, then in a braking
skid, where the wheels are no longer rolling,
release enough pressure on the brakes to get the
wheels rolling again. This restores steering
control. Push the brake pedal down steadily when
you have to stop suddenly. As long as the
wheels are rolling, you will have steering control.Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
•Drive defensively.
•Do not drink and drive.
•Adjust the inside rearview mirror to reduce the
glare from headlamps behind you.
•Since you cannot see as well, you may need
to slow down and keep more space between
you and other vehicles.
•Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
•In remote areas, watch for animals.
•If you are tired, pull off the road in a safe
place and rest.

No one can see as well at night as in the daytime.
But as we get older these differences increase.
A 50-year-old driver may require at least twice as
much light to see the same thing at night as a
20-year-old.
What you do in the daytime can also affect your
night vision. For example, if you spend the
day in bright sunshine you are wise to wear
sunglasses. Your eyes will have less trouble
adjusting to night. But if you are driving, do not
wear sunglasses at night. They may cut down on
glare from headlamps, but they also make a
lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or
even several seconds, for your eyes to re-adjust
to the dark. When you are faced with severe glare,
as from a driver who does not lower the high
beams, or a vehicle with misaimed headlamps,
slow down a little. Avoid staring directly into
the approaching headlamps.Keep the windshield and all the glass on your
vehicle clean — inside and out. Glare at night is
made much worse by dirt on the glass. Even
the inside of the glass can build up a film caused
by dust. Dirty glass makes lights dazzle and
flash more than clean glass would, making the
pupils of your eyes contract repeatedly.
Remember that the headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as the headlamps should be
checked regularly for proper aim, so should your
eyes be examined regularly. Some drivers suffer
from night blindness — the inability to see in dim
light — and are not even aware of it.
221

You will need a well-charged battery to restart the
vehicle, and possibly for signaling later on with
your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window
almost all the way to preserve the heat. Start
the engine again and repeat this only when you
feel really uncomfortable from the cold. But do it as
little as possible. Preserve the fuel as long as
you can. To help keep warm, you can get out of
the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
In order to free your vehicle when it is stuck, you
will need to spin the wheels, but you do not
want to spin your wheels too fast. The method
known as rocking can help you get out when you
are stuck, but you must use caution.
{CAUTION:
If you let your vehicle’s tires spin at high
speed, they can explode, and you or others
could be injured. And, the transaxle or
other parts of the vehicle can overheat.
That could cause an engine compartment
re or other damage. When you are stuck,
spin the wheels as little as possible. Do not
spin the wheels above 35 mph (55 km/h) as
shown on the speedometer.
Notice:Spinning the wheels can destroy parts
of your vehicle as well as the tires. If you
spin the wheels too fast while shifting
the transaxle back and forth, you can destroy
the transaxle. SeeRocking Your Vehicle to
Get It Out on page 236.
For information about using tire chains on your
vehicle, seeTire Chains on page 323.

Headlamp Aiming
Headlamp aim has been preset at the factory and
should need no further adjustment.
However, if your vehicle is damaged in an accident,
the headlamp aim may be affected. Aim adjustment
to the low-beam headlamps may be necessary if it
is difficult to see the lane markers (for horizontal
aim), or if oncoming drivers flash their high-beam
headlamps at you (for vertical aim).
If you believe your headlamps need to be
re-aimed, it is recommend that you take the vehicle
to your dealer for service.
Bulb Replacement
For the proper type of replacement bulbs, see
Replacement Bulbs on page 301.
For any bulb changing procedure not listed in this
section, contact your dealer.
Halogen Bulbs
{CAUTION:
Halogen bulbs have pressurized gas
inside and can burst if you drop or
scratch the bulb. You or others could be
injured. Be sure to read and follow the
instructions on the bulb package.
Headlamps
To replace a headlamp bulb, do the following:
1. Open the hood. SeeHood Release on
page 257for more information.
2. For wagon models, remove the two bolts from
the top of the headlamp assembly and one
nut on the inside that retains the headlamp
assembly.
For hatchback models, remove the four screws
and the radiator grill. Then remove the
three bolts and the headlamp assembly.
