ignition CHEVROLET EXPRESS CARGO VAN 2007 1.G Service Manual

With RDS, the radio can do the following:
•Seek to stations broadcasting the selected
type of programming
•Receive announcements concerning local and
national emergencies
•Display messages from radio stations
This system relies upon receiving specific
information from these stations and only works
when the information is available. In rare cases, a
radio station may broadcast incorrect information
that causes the radio features to work improperly.
If this happens, contact the radio station.
While the radio is tuned to an RDS station, the
station name or call letters appear on the display
instead of the frequency. RDS stations may
also provide the time of day, a program type (PTY)
for current programming, and the name of the
program being broadcast.

When cleaning the cassette tape player with the
recommended non-abrasive cleaning cassette,
it is possible that the cassette might eject, because
the cut tape detection feature on the radio can
recognize it as a broken tape, in error. To prevent
the cleaning cassette from being ejected, use
the following steps:
1. Turn the ignition on.
2. Turn the radio off.
3. Press and hold the TAPE DISC button for
five seconds. READY displays and the
cassette symbol flashes 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 activates again.
A non-scrubbing action, wet-type cleaner which
uses a cassette with a fabric belt to clean the tape
head can be used. This type of cleaning cassette
does not eject on its own. A non-scrubbing
action cleaner might not clean as thoroughly
as the scrubbing type cleaner. The use of a
non-scrubbing action, dry-type cleaning cassette
is not recommended.After the player is cleaned, press and hold the
eject button for five seconds to reset the CLEAN
indicator. The radio displays --- or CLEANED
to show the indicator was reset.
Cassettes are subject to wear and the sound
quality can degrade over time. Always make sure
the cassette tape is in good condition before
the tape player is serviced.
Care of Your CDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from
direct sunlight and dust. The CD player scans the
bottom surface of the disc. If the surface of a CD is
damaged, such as cracked, broken, or scratched,
the CD does not play properly or not at all. If the
surface of a CD is soiled, take a soft, lint free cloth
or dampen a clean, soft cloth in a mild, neutral
detergent solution mixed with water, and clean it.
Make sure the wiping process starts from the center
to the edge.
Do not touch the bottom side of a CD while handling
it; this could damage the surface. Pick up CDs by
grasping the outer edges or the edge of the hole
and the outer edge.
225

Care of the CD Player
Do not use CD lens cleaners for CD players
because the lens of the CD optics can become
contaminated by lubricants.
Fixed Mast Antenna
The fixed mast antenna can withstand most car
washes without being damaged. If the mast should
ever become slightly bent, straighten it out by
hand. If the mast is badly bent, replace it.
Check occasionally to make sure the mast is
still tightened to the fender. If tightening is
required, tighten by hand, then with a wrench
one quarter turn.
Chime Level Adjustment
The radio is used to adjust the vehicle’s chime
level. To change the volume level of the chime,
press and hold pushbutton 6 with the ignition on
and the radio power off. The volume level will
change from the normal level to loud, and LOUD
will appear on the radio display. To change back to
the default or normal setting, press and hold
pushbutton 6 again. The volume level will change
from the loud level to normal, and NORMAL will
appear on the radio display. Each time the chime
volume is changed, three chimes will sound to
indicate the change. Removing the radio and not
replacing it with a factory radio or chime module will
disable vehicle chimes.
