ignition CHEVROLET CLASSIC 2004 Owner's Manual

Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed.
•Use the accelerator pedal to get to the higher
speed. Press the SET DECEL button, then release
the button and the accelerator pedal. You’ll now
cruise at the higher speed.
•Press the ACCEL RESUME button. Hold it there until
you get up to the speed you want, and then release
the button. To increase your speed in very small
amounts, press the ACCEL RESUME button briefly
and then release it. Each time you do this, your
vehicle will go about 1 mph (1.6 km/h) faster.
The accelerate feature will only work after you turn on
the cruise control by pressing the SET DECEL button.
Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
•Press the SET DECEL button until you reach the
lower speed you want, then release it.
•To slow down in very small amounts, press the
SET DECEL button briefly. Each time you do
this, you’ll go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers find this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
•Step lightly on the brake pedal;
•Press OFF/ON.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Exterior Lamps
Headlamps
See “Headlamps” underTurn Signal/Multifunction Lever
on page 3-6.
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 at a reduced brightness when the following
conditions are met:
•The ignition is on,
•the exterior lamp control is turned to AUTO or you
have turned on your parking lamps,
•the light sensor detects daytime light,
•the parking brake is released, and
•the shift lever is not in PARK (P).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 remain off any time your vehicle is
in PARK (P) or the parking brake is engaged and the
vehicle speed is less than 8 mph (13 km/h), for
United States vehicles only.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Automatic Headlamp System
When it is dark enough outside, your Automatic
Headlamp System will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights will also be dim.
Your vehicle is equipped with a light sensor on the
top of the instrument panel under the defroster grill, so
be sure it is not covered which will cause the system
to be on whenever the ignition is on.
The system may also be on when driving through a
parking garage, heavy overcast weather or a tunnel.
This is normal.
3-13

There is a delay in the transition between the daytime
and nighttime operation of the DRL and the Automatic
Headlamp System so that driving under bridges or bright
overhead street lights does not affect the system. The
DRL and Automatic Headlamp System will only be
affected when the light sensor sees a change in lighting
lasting longer than this delay.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. See “Instrument
Panel Brightness Control” underInterior Lamps
on page 3-15.
To idle your vehicle with the system off, set the park
brake while the ignition is off. Then start the vehicle. The
system will stay off until you release the park brake.
As with any vehicle, you should turn on the regular
headlamps when you need them.Headlamps Off in Park (P)
This feature works when the ignition is on and it is dark
outside. To turn the headlamps off when it is dark outside,
turn the exterior lamp control to the parking lamp position.
In this position, the parking lamps, sidemarker lamps,
taillamps, license plate lamps and instrument panel lights
will be on, but the headlamps will be off.
To turn on the headlamps along with the other lamps
when it is dark outside, turn the exterior lamp control to
the AUTO or headlamp position.
Delayed Headlamps
The delayed headlamps feature will continue to
illuminate the headlamps for 20 seconds after the key is
turned to OFF at night. Then the headlamps will
automatically turn off.
To override the 20 second delayed headlamp feature
while it is active turn the switch at the end of the
turn signal/multifunction lever up one position and then
back to AUTO.

Interior Lamps
Instrument Panel Brightness
The thumbwheel for this
feature is located on the
instrument panel to the left
of the steering wheel.
Move the thumbwheel to the right to brighten the lights
or to the left to dim them.
Entry/Exit Lighting
When you open any door, the dome lamp inside your
vehicle will go on. This lamp will fade out 10 seconds
after the last door is closed, or when the ignition
is turned on after all doors have been closed. This lamp
will also go on when you press the trunk release
button, the unlock button or the horn button on the
remote keyless entry transmitter.
The lamps inside of your vehicle will stay on for about
10 seconds after your key is removed from the ignition to
provide an illuminated exit.
Dome Lamp
The switch on this lamp has three positions. The ON
position will turn on the lamp. The DOOR position
will turn on the lamp while a door is opened. The OFF
position will shut off the lamp completely, even while
a door is opened.
Trunk Lamp
The trunk lamp comes on when you open your trunk.
3-15

Battery Run-Down Protection
Your vehicle has a battery run-down protection feature
designed to protect your vehicle’s battery.
When any interior lamp (trunk, reading, footwell, visor
vanity or glove box) is left on when the ignition is turned
off, the battery run-down protection system will
automatically shut the lamp(s) off after 20 minutes. This
will avoid draining the battery.
To reactivate the interior lamps, do one of the following:
•Turn on the ignition,
•turn the exterior lamp control off and then on,
•open a door,
•press any remote keyless entry transmitter button
(if equipped),
•press the remote trunk release button, or
•press the power door lock switch.
The battery run-down feature will also be activated
when any door on the vehicle is left open and the
ignition is in OFF.
Accessory Power Outlets
With accessory power outlets you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
The accessory power outlet is located to the right of the
ashtray.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem see your dealer for additional information
on accessory power outlets.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensor, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, seeSupplemental Restraint System (SRS)
on page 1-56.
This light will come on
when you start your
vehicle, and it will flash for
a few seconds. Then the
light should go out. This
means the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to ON. If the
light doesn’t come on then, have it fixed so it will
be ready to warn you if there is a problem.
3-26

Charging System Light
The charging system light
will come on when you
turn on the ignition, but the
engine is not running, as
a check to show you it
is working.
When the engine is running, the light should go out.
If it stays on, or comes on while you are driving and you
hear a chime, you may have a problem with the
electrical charging system. It could indicate that you
have a loose generator drive belt or another electrical
problem. Have it checked right away. 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.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into two
parts. If one part isn’t 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 key to ON. If it
doesn’t come on
then, have it fixed so it will
be ready to warn you if
there’s 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 doesn’t
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
3-27

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 4-29.
{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 the
anti-lock brake system, the
light will come on when
your engine is started and
may stay on for several
seconds. That’s normal.
If the light stays on, turn the ignition to OFF. Or, if the light
comes on and the chime sounds when you’re driving,
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’re driving, your
vehicle needs service. If the regular brake system
warning light isn’t on, you still have brakes, but you don’t
have anti-lock brakes. If the regular brake system
warning light is also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
Brake System Warning Light on page 3-27earlier in this
section.
The anti-lock brake system warning light will come on
briefly when you turn the ignition key to ON. This is
normal. If the light doesn’t come on then, have it fixed
so it will be ready to warn you if there is a problem.
3-28

Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
If the gage pointer moves into the red area, the light
comes on and you hear a chime, your engine is too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-22.
Low Coolant Warning Light
This light comes on
briefly when you turn
your ignition ON.
If this light comes on and stays on, the coolant level in
your vehicle is low. SeeEngine Coolant on page 5-19.
If the light is on along with an overheat warning,
you may have a serious overheating problem, see
Engine Coolant Temperature Gage on page 3-29.
Notice:If you operate the engine without coolant
or fail to maintain the cooling system properly,
you could damage the engine. The repairs would not
be covered by your warranty. Always follow the
maintenance schedule in this manual for
maintaining your cooling system. SeeCooling
System on page 5-25for more information.
SeeEngine Overheating on page 5-22for information
on what to do. Your vehicle should be serviced as soon
as possible.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner environment.
The Check Engine light comes on to indicate that there is
a problem and service is required. Malfunctions often will
be indicated by the system before any problem is
apparent. This may prevent more serious damage to your
vehicle. This system is also designed to assist your
service technician in correctly diagnosing any
malfunction.Notice:If you keep driving your vehicle with this
light on, after a while, your emission controls
may not work as well, your fuel economy may not
be as good and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.
Notice:Modications made to the engine,
transaxle, exhaust, intake or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
