2002 CADILLAC SEVILLE air condition

3-4
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is
helpful when you are trying to cool the air quickly or
limit odors entering your vehicle. Press this button again
to turn off the recirculation feature.
If you notice the windows fogging, press the
recirculation button to exit the recirculation mode.
Recirculation is not available in the defrost mode.
A/C (Air Conditioning): Press this button to turn the
air conditioning compressor on and off. The system will
cool and dehumidify the air inside the vehicle.
When the compressor is off, A/C OFF appears on the
climate control panel display. Press the button again and
the compressor will turn back on.
The A/C OFF feature is not available in the
defrost mode.
AUTO (Automatic): The AUTO button will turn on the
system and automatically adjust the fan speed, air
delivery mode and temperature to your previously
programmed settings.When the system is set for automatic operation, sensors
will control the air delivery mode. Air will come from
the floor ducts, the instrument panel or windshield
outlets. The fan speed will vary as the system maintains
the selected temperature setting.
To find your comfort zone, start with the 75
F (24
C)
setting and allow about 30 minutes for the system to
regulate. Turn the TEMP knob to adjust the temperature if
necessary. If you choose 60
F (16
C), the system will
remain at that maximum cooling setting and will not
regulate fan speed. If you choose 90
F (32
C), the system
will remain at that maximum heating setting and will not
regulate fan speed. Choosing either maximum setting will
not cause the system to heat or cool any faster.
With the automatic setting, the air conditioning
compressor cycles on and off when needed to cool the
air. In cold weather, when the system senses the need for
heat, the airflow will be directed out the floor ducts. As
the interior temperature approaches a desired setting, the
fan speed will decrease. To maintain interior comfort,
the airflow may move to the instrument panel air outlets
and floor ducts. On bright sunny days in cold weather,
the airflow may come out of the instrument panel outlets
to maintain comfort and prevent stuffiness.

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.

3-10 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.
!~
(Fan): Press the up arrow on the control to increase
the fan speed and the down arrow to decrease fan speed.
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.

4-16
With Stabilitrak
, you may see the STABILITY SYS
ENGAGED message on the Driver Information Center.
See ªStability Sys Engaged Messageº in the Index.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you'll
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting to a lower
gear). Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until your
vehicle is skidding. Learn to recognize warning
clues
-- such as enough water, ice or packed snow on
the road to make a ªmirrored surfaceº
-- and slow
down when you have any doubt.
Remember: Any anti
-lock brake system (ABS) helps
avoid only the braking skid.
Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired
-- by alcohol or drugs, with night vision
problems, or by fatigue.

Towing Your Vehicle
Consult your dealer or a professional towing service
if you need to have your disabled vehicle towed. See
ªRoadside Assistanceº in the Index. If you want to
tow your vehicle behind another vehicle for recreational
purposes (such as behind a motorhome), see
ªRecreational Vehicle Towingº in the Index.
Engine Overheating
You will find an ENGINE COOLANT HOT, IDLE
ENGINE message or an ENGINE OVERHEATED,
STOP ENGINE message on the Driver Information
Center (DIC). There is also an engine temperature
warning light and/or gage on the instrument panel.
See ªEngine Coolant Temperature Warning Lightº or
ªEngine Coolant Temperature Gageº in the Index.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the message
ENGINE OVERHEATED, STOP ENGINE is displayed,
an overheat protection mode which alternates firing
groups of cylinders helps prevent engine damage. In this
mode, you will notice a loss in power and engine
performance. This operating mode allows your vehicle
to be driven to a safe place in an emergency; you may
drive up to 50 miles (80 km). Driving extended miles
(km) and/or towing a trailer in the overheat protection
mode should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life system. See ªEngine Oilº in the Index.

6-4 Gasoline Specifications
It is recommended that gasoline meet specifications
which were developed by the American Automobile
Manufacturers Association and endorsed by the
Canadian Vehicle Manufacturers' Association for better
vehicle performance and engine protection. Gasolines
meeting these specifications could provide improved
driveability and emission control system performance
compared to other gasolines.
In Canada, look for
the ªAuto Makers'
Choiceº label on
the pump.
Canada Only
California Fuel
If your vehicle is certified to meet California Emission
Standards (see the underhood emission control label),
it is designed to operate on fuels that meet California
specifications. If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp may
turn on (see ªMalfunction Indicator Lampº in the Index)
and your vehicle may fail a smog
-check test. If this
occurs, return to your authorized GM dealer for
diagnosis. If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered by
your warranty.
