2002 CHEVROLET IMPALA Owners Manual

3-5 Rear Window Defogger
Press the button marked
REAR to turn the
defogger on. An indicator
in the button will light.
When turned on, the rear window defogger uses a
warming grid to remove fog from the rear window.
If your vehicle has the optional heated outside mirrors,
they will heat to clear the surface of the mirrors.The rear window defogger and the outside rearview
mirrors will automatically turn off after about 15 minutes.
If you turn them on again, the defogger and the outside
rearview mirrors will only stay on for about seven and
one half minutes before turning off again. You can also
turn them off by turning the ignition off or by pressing
the button again.
Do not attach anything like a temporary vehicle license
or decal across the defogger grid.
NOTICE:
Don't use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.
Don't put decals there because you might have to
scrape them off.

3-6 Ventilation System
Change the direction
of the airflow by
adjusting the vents.
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 (if equipped) 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.

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.

RDS Messages
ALERT!: Alert warns of national or local emergencies.
You will not be able to turn off alert announcements.
ALERT! appears on the display when an alert
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.
INFO (Information): If the current station has a
message, the information symbol will appear on the
display. These text messages are from the RDS
broadcaster to the listening public and may be general
information such as artist and song title, call in phone
numbers, etc. Press this button to see the message.
If the whole message does not appear on the display,
parts of the message will appear every three seconds
until the message is completed. To scroll through the
message at your own speed, press the INFO button
again for less than 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 the display until
another new message is received. The old message can
be displayed by pressing the INFO button until a new
message is received or a different station is tuned to.
When a message is not available from an FM station,
NO INFO will be displayed.
TRAF (Traffic): Press this button to receive traffic
announcements. If the current station does not broadcast
traffic announcements, the radio will seek to a station
that does. The traffic symbol will flash on the display.
When the radio finds a station that broadcasts traffic
announcements, it will stop. If no station is found,
NO TRAF will appear on the display.
Your radio can be programmed to interrupt the playback
of a cassette tape or FM radio by enabling the traffic
interrupt feature. Press the TRAF button once to seek
to an RDS station that supports the traffic interrupt
feature if the current station does not. The traffic
symbol will flash on the display when seeking for a
station that supports traffic interrupt. When the traffic
interrupt feature is on, the traffic symbol will appear on
the display.
