2002 CADILLAC DEVILLE air conditioning

3-11 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 airflow 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 can be determined by
which transmitter is used to unlock the vehicle. When
the button with the unlock symbol is pressed, the
settings will be automatically recalled for that driver.
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 to use the
vehicle. If these are not the correct settings for you,
press the button with the unlock symbol on remote
keyless entry transmitter that was used when you saved
your settings.The settings can also be recalled 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 more programming information, see ªMemory and
Personalization Featuresº in the Index.

7-21 Fuel System Inspection
Inspect the complete fuel system for damage or leaks.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the outside
of the radiator and air conditioning condenser. To help
ensure proper operation, a pressure test of the cooling
system and pressure cap is recommended at least once
a year.
Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts as
needed. Replace any components that have high effort
or excessive wear. Do not lubricate accelerator and
cruise control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook
-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. You may need to
have your brakes inspected more often if your driving
habits or conditions result in frequent braking.
