2002 CHEVROLET MONTE CARLO Owners Manual

3-6 Ventilation System
Adjust the amount of
airflow by moving the
thumbwheel located
underneath or on the sides
of the air vents. Change the
airflow direction by moving
the thumbwheel below the
vents to the right or left.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
compressor is running and the outside air button
is pressed.
If the airflow seems very low when the fan is adjusted to
the highest setting, regardless of the mode setting, your
passenger compartment air filter may need to be
replaced. See ªMaintenance Scheduleº and ªPassenger
Compartment Air Filterº in the Index.Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, adjust the
mode knob to floor and the fan to the highest speed
for a few seconds before driving off. This helps clear
the intake ducts of snow and moisture and reduces
the chance of fogging the inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off. See
ªRetained Accessory Powerº in the Index.

Using RDS Mode
Your audio system is equipped with a Radio Data
System (RDS). RDS is a system that receives data along
with the audio of the FM station you are currently tuned
to. RDS displays program information and can control
your radio. With RDS, the radio can do the following:

Seek only to stations with the types of programs you
want to listen to,

seek to stations with traffic announcements,
receive announcements concerning local and
national emergencies, and

receive and display messages from radio stations.
RDS features are only available on FM stations that
broadcast RDS information. The RDS features on
your radio rely on receiving specific RDS information
from these stations. These features will only work when
the RDS information is available. In rare cases, a radio
station may broadcast incorrect information that will
cause the radio features to work improperly. If this
happens, contact the radio station.
When you are tuned to an RDS station, the station
name will appear on the display, instead of the
frequency. Most RDS stations provide their station
name, the time of day and a Program Type (PTY) for
their current programming. Some stations also provide
the name of the current program.

announcement plays. When an alert announcement
comes on the current radio station, you will hear it,
even if the volume is muted or a cassette tape is
playing. If the cassette tape player is playing, play
will stop for the announcement and resume when
the announcement is finished.
This function will only work during actual emergency
broadcasts, and will not work during tests of the
emergency broadcast system. This feature is not
supported by all RDS stations.

your own speed, press the INFO button again for lessthan one second. A new group of words will appear on
the display. Once the complete message has been
displayed, the information symbol will disappear from

Playing a Cassette Tape
Your tape player is built to work best with tapes that are
up to 30 to 45 minutes long on each side. Tapes longer
than that are so thin they may not work well in this
player. The longer side with the tape visible should face
to the right. If the ignition is on and the radio is off,
the tape can be inserted and will begin playing. A tape
symbol is shown on the display whenever a tape is
inserted. If you hear nothing but a garbled sound, the tape may not be in squarely. Press EJT to remove
the tape and start over. If you want to insert a tape when
the ignition is off, first press EJT or DISP.

current selection has been playing from 3 to 13 seconds,
it will go to the beginning of the previous selection or the
