2007 CHEVROLET OPTRA 5 service reset

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.

Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
•At the service station, the gas pump shuts off
before the gage reads full.
•It takes a little more or less fuel to fill up than
the gage indicated. For example, the gage may
have indicated the tank was half full, but it
actually took a little more or less than half the
tank’s capacity to fill the tank.
•The indicator moves a little when you turn a
corner or speed up.
•The gage goes back to empty when you turn off
the ignition.
Low Fuel Warning Light
This light comes on
when the fuel tank is
low on fuel.The low fuel warning light comes on when there is
about 2.0 gallons (7.5 liters) of fuel remaining in
the tank.
To turn the light off, add fuel to the fuel tank.
SeeFilling the Tank on page 254.
Audio System(s)
Determine which radio your vehicle has and then
read the pages following to familiarize yourself
with its features.
Driving without distraction is a necessity for a
safer driving experience. SeeDefensive Driving on
page 206. By taking a few moments to read this
manual and get familiar with your vehicle’s
audio system, you can use it with less effort, as
well as take advantage of its features. While your
vehicle is parked, set up your audio system by
presetting your favorite radio stations, setting the
tone and adjusting the speakers. Then, when
driving conditions permit, you can tune to
your favorite stations using the presets and
steering wheel controls if the vehicle has them.

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.
