2001 CADILLAC SEVILLE Owners Manual

3-6 Electronic Solar Sensor
The sensor monitors the sun's solar radiation and is
located near the end of the instrument panel near
the windshield.
The climate control panel uses this information to
automatically make the necessary temperature and
airflow adjustments to maintain your comfort. The
climate control system may supply cooler air to one side
of your vehicle, if that side is facing the sun. Be careful
not to put anything over the sensor on top of the
instrument panel.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best. Your A/C setting
may be adjusted automatically or manually. It may also
be set separately on the passenger's side from the
driver's side. See ªClimate Control Panelº earlier in
this section.
Heating
Adjust the interior temperature to a comfortable level
and if the fan speed needs adjusting, press the up or
down arrow. Adjusting the fan speed will cancel the cold
air delay.
Outside air will be brought in and sent through the floor,
air conditioning or bi
-level outlets. The heater works
best if you keep your windows closed while using it. In
automatic operation, your fan will not run at high speed
to minimize warm
-up time.

3-7 Defrosting and Defogging
Use defrost (front) on cool and humid days to keep the
windshield and side windows clear. This setting will
remove fog or ice from the windshield quickly in
extremely humid or cold conditions. If you desire to
have more air on your feet, turn the control to the defog
mode. You may do this by pressing the right or left
arrow on the MODE button.
Press the up or down arrow on the fan button to control
the blower speed. You may also adjust the temperature
by turning the TEMP knob.
The recirculation mode and the A/C OFF message are
not available in the defrost mode.
Rear Window Defogger
The grid lines you see on
the rear window warm the
glass. Press this button to
turn on the rear defogger.With it, the rear window and both outside rearview
mirrors are heated. The light on the button will come on
while the system is activated.
The system will automatically shut off after 10 minutes.
If further defogging is desired, press the button again.
The system will automatically shut off after five minutes
for any cycles after the initial activation.
The lines along the top of the window are for the
diversity antenna and are not intended to defog the
rear window.
Do not attach a temporary vehicle license, tape or decals
across the defogger grid on the rear window.
NOTICE:
Scraping the inside of your rear window could
cut and damage the heating grids. Your warranty
would not cover this damage. Don't put decals
there because you might have to scrape them off.

3-8 Ventilation System
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 heater or the air
conditioning fan is running.
The front outlets are located in the center and at each
side of the instrument panel. You can adjust the
direction of airflow by moving the center control levers
or you can stop the airflow by moving the thumbwheel
located on each outlet downward.Rear Ventilation
The direction and quantity of airflow for the rear seats
can also be adjusted at the back of the console. Heater
outlets are located under the front seat to warm the feet
of rear passengers.
Move the fan lever to adjust the blower speed from LO
to HI. Adjust the knob to direct the air flow. To reduce
airflow to the rear outlets, slide the fan lever all the way
to the left. Turning the knob to OFF will completely
stop airflow, no matter where the fan blower control
is set.

3-9
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 the windows.

Keep the air path under the front seats clear
of objects. This helps circulate air throughout
your vehicle.
Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment filter, which is part of a three
-piece filter
system. The carbon
-treated filter removes certain
contaminants from the air, including pollen and dust
particles. Reductions in airflow, which may occur more
quickly in dusty areas, indicate that the filter needs to be
replaced early.The filter is located inside the air control module, with
an access panel under the instrument panel near the
accelerator pedal. The filter should be replaced as part
of routine scheduled maintenance. See the Maintenance
Schedule booklet for replacement intervals. See your
dealer for details on changing the filter.
Your vehicle will not be damaged if you choose not to
replace the filter once the old one is removed.

3-10 HVAC Steering Wheel Controls
(If Equipped)
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. See ªAudio
Steering Wheel Controlsº in
the Index.
FAN: Press the up arrow on the control to increase
the fan speed and the down arrow to decrease fan speed.
TEMP: Press the up arrow on the control to increase the
temperature and the down arrow to decrease temperature.
Climate Control Personalization
(If Equipped)
With this feature, your vehicle will recall the latest
climate control settings as adjusted the last time your
vehicle was operated. These settings include the set
temperatures for driver and passenger, air conditioning,
mode and fan speed. (This feature does not recall
recirculation or defrost modes.) This feature allows two
different drivers to store and recall their own climate
control settings. The settings recalled by the climate
control system are determined by which Remote
Keyless Entry (RKE) transmitter (ª1º or ª2º) was used
to enter the vehicle. The number on the back of the RKE
transmitter corresponds to driver 1 or to driver 2. After
any button is pressed on the RKE transmitter or the key
is placed in the ignition, the climate control settings will
automatically adjust to where they were last set. The
settings can also be changed by briefly pressing buttons
1 or 2 located on the driver's door.

your cassette tape is done playing, auto reverse plays theother side of your cassette tape. Cassette tapes may be
loaded with the radio off but they will not start playing
until the radio is on. If you want to insert a cassette tape
when the ignition is off, first press the eject button.
While the tape is playing, use the VOL, TONE, LEVEL,
and SPEAKER controls just as you do for the radio.
Other controls may have different functions when a tape
is inserted. The display will show an underlined tape
symbol. TAPE PLAY will appear on the display when a
tape is playing, with an arrow to indicate which side of
the tape is playing.
If an error occurs while trying to play a cassette tape, it
could be that:

The cassette tape is tight and the cassette player
cannot turn the hubs of the tape. Hold the cassette
tape with the open end down and try turning the right
hub counterclockwise with a pencil. Flip the tape
over and repeat. If the hubs do not turn easily, your
cassette tape may be damaged and should not be
used in the player. Try a new tape to be sure your
player is working properly.

The cassette tape is broken. (Check to see if your
tape is broken. Try a new tape.)
