Rear Climate Control System
Your Envoy has one of the following rear climate control
systems. With any of these systems, the rear climate
controls will be disabled when the front climate control
system is in defrost. This occurs to provide maximum
airow to clear the windshield.
The temperature of the air coming through the rear
outlets is determined by the front passenger’s
temperature setting. Press the PWR button to turn the
rear climate controls on and off. Use the mode knob
to change the direction of airow (upper, bi-level or oor)
to the rear seat area.If your vehicle has the rear seat audio system, the lower
buttons are used to adjust the rear seat climate
controls. The temperature of the air coming through the
rear outlets is determined by the front passenger’s
temperature setting.
If the front climate control is on and not in defrost mode,
the rear climate control can be enabled by pressing the
lower power button (center button) on the control face.
If the front is off or is in defrost mode, the rear climate
control will ash “OFF” if the power button is pressed,
indicating the function is unavailable at this point.
The fan speed is controlled by the fan speed toggle
button. The mode button, on the right, controls where
the air is vented.

Audio System(s)
Notice:Before you add any sound equipment to
your vehicle – like a tape player, CB radio, mobile
telephone or two-way radio – be sure you can
add what you want. If you can, it’s very important to
do it properly. Added sound equipment may
interfere with the operation of your vehicle’s engine,
radio or other systems, and even damage them.
Your vehicle’s systems may interfere with the
operation of sound equipment that has been added
improperly.
So, before adding sound equipment, check with
your dealer and be sure to check federal rules
covering mobile radio and telephone units.
Your audio system has been designed to operate easily
and to give years of listening pleasure. You will get
the most enjoyment out of it if you acquaint yourself with
it rst. Figure out which radio you have in your vehicle,
nd 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
“Retained Accessory Power (RAP)” underIgnition
Positions on page 2-20.
Setting the Time
Your radio may have a button marked with an H or HR
to represent hours and an M or MN to represent
minutes.
Press and hold the hour button until the correct hour
appears on the display. AM or PM will appear on
the display. Press and hold the minute button until the
correct minute appears on the display. The time may be
set with the ignition on or off.
To synchronize the time with an FM station broadcasting
Radio Data System (RDS) information, press and
hold the hour and minute buttons at the same time for
two seconds until UPDATED and the clock symbol
appear on the display. If the time is not available from
the station, NO UPDAT will appear on the display.
RDS time is broadcast once a minute. Once you have
tuned to an RDS broadcast station, it may take a
few minutes for your time to update.

Radio with CD
If your vehicle is equipped with the Bose®audio
system, your vehicle will have six Bose®amplied
speakers.
Radio Data System (RDS)
Your audio system is equipped with a Radio Data
System (RDS). RDS features are available for use only
on FM stations that broadcast RDS information.
With RDS, your 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
Seek to stations with traffic announcements
This system relies upon receiving specic information
from these stations and will only work when the
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.
While you are tuned to an RDS station, the station
name or the call letters will 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. Base Radio Shown, Bose®Similar
