2002 CADILLAC SEVILLE Owners Manual

3-5
If your vehicle is sitting in direct sunlight on a hot day
and you have the climate control system in AUTO, the
air will first flow out the floor ducts for a few seconds.
This is normal. This removes hot air from the air outlets.
As the air is cooled, the airflow will enter the vehicle
through the instrument panel outlets.
To avoid blowing cold air in cold weather, the system
will start at a reduced fan speed until warm air is
available. The length time required for this to happen
depends on the outside air temperature, engine coolant
temperature or the time since the engine was last started.
As the coolant warms up, the fan speed will gradually
increase and air will flow from the floor ducts, with
some airflow to the windshield to prevent fogging under
most normal conditions. If you select defrost mode or a
fan speed manually, this function will be canceled.
If you leave your vehicle, the system will remember
the control setting the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation. Defrost will change to automatic
operation when the ignition is shut off and then turned
back on.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 sure not to put anything over the electronic solar
sensor. If you do, the climate control system may not
function properly.

3-6 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 for more information.
Heating
Adjust the interior temperature to a comfortable level.
If the fan speed needs adjusting, press the up or down
arrow on the fan switch. Adjusting the fan speed will
cancel the cold air delay.
Outside air will be brought in and sent through the floor
ducts and the instrument panel 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.
Defogging and Defrosting
Use FRONT (defrost) 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 switch to control
the fan speed. You may also adjust the temperature by
turning a TEMP knob.
Recirculation and the A/C OFF feature are not available
in the defrost mode.

3-7 Rear Window Defogger
The grid lines you see on the rear window warm the
glass. When the rear window defogger is turned on, the
rear window and both outside rearview mirrors are heated
to remove snow and ice from the surface of the glass.
The rear window defogger
button is located on the
climate control panel near
the bottom left corner.
Press the button to turn on the rear defogger. The light in
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.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 or the
integrated rear window antenna, and the repairs
wouldn't be covered by your warranty.
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.

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 fan is running.
The vent 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 rear of the center console.
Floor ducts are located under the front seat to warm the
feet of rear passengers.
Move the fan lever to adjust the fan 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, regardless of the fan setting.

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.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 ªMaintenance
Scheduleº in the Index for replacement intervals. See
your dealer for assistance when 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.
~TEMP !(Temperature): Press the up arrow on
the control to increase the temperature and the down
arrow to decrease temperature.

Climate Control Personalization
(If Equipped)
This feature allows two different drivers to store and
recall their own climate control settings. These settings
include the set temperatures for the driver and front
passenger, the air conditioning, the mode and the
fan speed. (This feature does not recall recirculation
or defrost).
Each driver (1 or 2) has a corresponding number located
on the back of the remote keyless entry transmitter.
Settings recalled by the system are determined by which
transmitter is used to unlock the vehicle. After the
button with the unlock symbol is pressed, the settings
are automatically recalled.
The settings can also be recalled when the key is placed
in the ignition. If the settings are recalled this way, the
system will recall the settings of the last driver. If these
are not the correct settings, you must press the button
with the unlock symbol on remote keyless entry
transmitter that was used when you saved your settings.

3-11
The settings can be changed by briefly pressing the
corresponding memory button (1 or 2) located on the
driver's door panel.
Further programming for recalling climate control
personalization settings can be done using the DIC.
You can select or not select the following:

Automatic recall of the climate control settings when
the vehicle is unlocked with the remote keyless entry
transmitter, or

Automatic recall of the climate control settings when
a key is placed in the ignition.For programming information, see ªVehicle
Programming and Personalization Featuresº in
the Index.
Your vehicle is equipped with a dual
-zone electronic
climate control system. This system can automatically
adjust and control temperature, fan speed, air delivery
mode, air conditioning operation and air intake. You can
use the AUTO (automatic) setting or override the
automatic operation by manually altering the controls.
