2000 CHEVROLET VENTURE radio

When using a scrubbing action, non-abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a cut tape detection feature
and a cleaning cassette may appear as a broken tape.
To prevent the cleaning cassette from being ejected,
use the following steps.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape Player:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.
3. Press and hold the TAPE button for five seconds.
CAS will flash on the display for five seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
If your vehicle is equipped with the AM
-FM Stereo with
Cassette Tape and Compact Disc Player with Radio Data
System and Programmable Equalization:
1. Turn the ignition to RUN or ACCESSORY.
2. Turn the radio off.3. Press and hold the TAPE CD button for five seconds.
READY will appear on the display for five seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
When the cleaning cassette has been ejected, the cut tape
detection feature is active again.
You may also choose a non
-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own. A non
-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use of a non
-scrubbing action, dry-type cleaning
cassette is not recommended.
After you clean the player, press and hold the cassette
eject symbol or EJT button for five seconds to reset the
CLEAN or CLN indicator. The radio will display
CLEANED or
--- to show the indicator was reset.
Cassettes are subject to wear and the sound quality may
degrade over time. Always make sure the cassette tape
is in good condition before you have your tape
player serviced.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic transaxle
in PARK (P) or a manual transaxle in NEUTRAL
before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet. Turn off all
lamps that aren't needed, as well as radios. This will
avoid sparks and help save both batteries. In
addition, it could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
4. Open the hoods and locate the batteries.
Find the positive (+) and negative (
-) terminals on
each battery.
CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.

6-58 Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in the instrument panel fuse panel. An electrical
overload will cause the lamps to go on and off, or in
some cases to remain off. If this happens, have your
headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem, be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the instrument panel fuse panel
protect the power windows and other power accessories.
When the current load is too heavy, the circuit breaker
opens and closes, protecting the circuit until the problem
is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links.
Look at the silver
-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one that has the same
amperage or use one of the spare fuses in the underhood
fuse and relay center. Just pick some feature of your
vehicle that you can get along without
-- like the radio
or cigarette lighter
-- and use its fuse, if it is the right
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the
instrument panel fuse block and the underhood fuse
and relay center.
