2004 Chevrolet Optra Owner ManualM

Vehicle Damage Warnings
Also, in this manual you will find these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage your
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see CAUTION
and NOTICE warnings in different colors or in different
words.
There are also warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along with
the text describing the operation or information
relating to a specific component, control, message,
gage, or indicator.
If you need help figuring out a specific name of a
component, gage, or indicator, reference the following
topics:
•Seats and Restraint Systems in Section 1
•Features and Controls in Section 2
•Instrument Panel Overview in Section 3
•Climate Controls in Section 3
•Warning Lights, Gages, and Indicators in Section 3
•Audio System(s) in Section 3
•Engine Compartment Overview in Section 5

Sun Visors
To block out glare you can swing down the visors. You
can also remove them from the center mount and
swing them to the side.
Visor Vanity Mirror
Your vehicle also has vanity mirrors located on the back
of the sun visors. Swing down the sun visor and lift
the cover to expose the vanity mirror.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Theft-Deterrent System
Your vehicle may have a theft-deterrent system.
The theft-deterrent system will not arm when you lock
the doors using the key or the manual door lock. It
activates only when you use the optional remote keyless
entry transmitter.
Arming the System
To arm the system, do the following:
1. Turn the key to LOCK and remove the key from the
ignition.
If the key is inserted in the ignition, the transmitter
will not operate the theft-deterrent system.
2. Close the doors, the windows, the hood, and the
trunk or liftgate.
Make sure the windows are closed, as the system
can be activated even if the windows are open.
3. Lock the door using the remote keyless entry
transmitter. The transmitter must be used to activate
the theft-deterrent system.
•The LED on the transmitter will flash once.
•All of the doors will lock.
•The hazard warning lamps will flash once and
the horn will chirp.
•The theft-deterrent mode will activate.
•The security light will flash once every second to
indicate that the theft-deterrent system is armed.
The security light is located on the base of
the driver’s door lock.

Notice:If your key seems stuck in LOCK and you
can not turn it, be sure you are using the correct
key; if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. Turn the key only with your hand. Using a
tool to force it could break the key or the ignition
switch. If none of these works, then your vehicle
needs service.
LOCK:This position locks your steering wheel, ignition,
shift lever and transaxle. This is the only position in which
you can insert or remove the key. For easier key
operation when unlocking the steering wheel, move the
steering wheel from right to left and turn the key to ACC.
ACC (ACCESSORY):This position operates some of
your electrical accessories, such as the radio, but
not the ventilation fan.
ON:This is the position to which the switch returns
after you start your engine and release the key.
The switch stays in ON when the engine is running. But
even when the engine is not running, you can use
ON to operate your electrical accessories, and to display
some instrument panel warning lights.START:This position starts the engine. When the
engine starts, release the key. The switch will return to
ON for normal driving. Do not turn the key to START
if the engine is running.
Even if the engine is not running, ACC and ON allow
you to operate electrical accessories, such as the radio.
Starting Your Engine
Automatic Transaxle
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position — that’s a
safety feature. To restart when you’re already moving,
use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
Manual Transaxle
The gear selector should be in neutral and the parking
brake engaged. Hold the clutch pedal to the floor
and start the engine. Your vehicle won’t start if the clutch
pedal is not all the way down – that’s a safety feature.

Shift Speeds
{CAUTION:
If you skip a gear when you downshift, you
could lose control of your vehicle. You could
injure yourself or others. Don’t shift down
more than one gear at a time when you
downshift.
Parking Brake
The parking brake lever is located between the bucket
seats.
To set the parking brake, hold the brake pedal down
and pull up on the parking brake lever. If the ignition is
on, the brake system warning light will come on.
SeeBrake System Warning Light on page 3-30.
2-28

To release the parking brake, hold the brake pedal
down. Pull the parking brake lever up until you can press
the release button. Hold the release button in as you
move the brake lever all the way down.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
Shifting Into Park (P) (Automatic
Transaxle)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set.
CAUTION: (Continued)
CAUTION: (Continued)
Your vehicle can roll. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, use the steps
that follow.
1. Hold the brake pedal down and set the parking
brake.
2. Move the shift lever into the PARK (P) position by
pushing the lever toward the passenger side of the
vehicle and then up.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
