Malfunction Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENGINE
SOON
Your Cadillac is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called OBD
I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life
of the vehicle, helping to produce a cleaner
environment. (In Canada, OBD I1 is replaced by
Enhanced Diagnostics.) The SERVICE
ENGINE SOON
light comes on to indicate that there is a problem and
service is required. Malfunctions often will
be indicated
by the system before any problem is apparent, which
may prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
-
If you keep driving your vehicle with this light
on, after
a while, your emission controls may not
work
as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered
by your warranty.
This light should come on, as a check to show you it is
working, when
the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
Light FIashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service
is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle. Dealer or qualified service center diagnosis and
service may be required.

The following may prevent more senous damage to
your vehicle:
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
e Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
0 If towing a trailer, reduce the amount of cargo being
hauled as soon as
it is possible. Did you
just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine
may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition.
Make sure to install the fuel cap properly. It
will take a few driving trips to
turn the light off.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when
it is safe to do so,
stop the vehicle. FW your vehicle in PARK (P). Turn the
key off, wait at least
10 seconds and restart the engine.
If the light remains on steady, see “If the Light Is On
Steady” following.
If the light is still flashing follow the
previous steps, and drive
the vehicle to your dealer or
qualified service center for service.

Downloaded from www.Manualslib.com manuals search engine Fan Button
The button with the fan symbol adjusts the fan speed. Press the up
arrow to increase fan speed and the down
arrow to decrease fan speed.
Temperature Button
The red and blue temperature buttons adjust the air
temperature coming through the system. Press the blue
button for a eooler setting or the red button for a warmer setting. The outside temperature is always displayed
when your vehicle is running.
You can change it from
Fahrenheit to Celsius by pressing the
ENGNET
(English/metric) button on the DIC.
Mode Controls
The AUTO/ECON button automatically controls the
direction
of air delivery for air conditioning and non-air
conditioning modes.
Automatic Operation
When the system is set for AUTO, sensors will control
the air delivery mode.
Air will come from the floor,
middle or windshield outlets. The fan speed will vary as
the system maintains the selected temperature setting. Be
careful not to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor
is used by the automatic system
to regulate temperature.
To find your comfort zone, start with 75°F (24°C)
setting, allow about 20 minutes for the system to
regulate. Press the red or blue temperature buttons to
adjust the temperature if necessary. If you choose
60°F
(1 6" C), the system will remain at that maximum cooling
setting
and will not regulate fan speed. If you choose the
temperature of
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 this setting,
the air conditioning compressor
automatically cycles 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 outlets. As. the
interior temperature approaches a desired setting, the
blower speed will decrease.
To maintain interior
comfort, the airflow may move to the instrument panel
air outlets and floor outlets
(BI-LEVEL mode). On
bright, sunny days in cold weather, the airflow may
come
out of the A/C outlets (A/C mode) to maintain
comfort and prevent stuffiness.

If your vehicle is sitting out on a hot day and you have
it set -on
AUTO, the air will first flow out the floor air
outlets for a
few seconds. That is normal. This is to
expel hot air in the air outlets.
As the air is cooled, the
aifflow will move through the
A/C outlets. If you start
your vehicle with the fan setting on
HI, it will skip the
A/C Purge.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started.
As the coolant warms
up, the blower fan speed will gradually increase
and air
will flow from the heater outlets, with some aifflow to
the windshield to prevent fogging under most nonnal
conditions.
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, whereas,
DEFROST will change
to
AUTO when the ignition is shut off and then turned
back on.
Manual Operation
RECIRCULATION: Press this button to limit the
amount of fresh air entering your vehicle. This is helpful
when you are trying to cool the air quickly or limit odors
entering your vehicle. In the
AUTO mode, the system
will use recirculation as necessary to cool the air.
Pressing the recirculation button will change the
operation to a manual mode and the air will recirculate
non-stop. 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.
OFF: Press this button to turn the system off.
Fresh air will continue to flow through the vehicle,
and the system will try
to maintain the previously set
temperature. The outside temperature will show in
the display when the system is off.
@ DE-ICE (Option): Pressing this button helps to
remove ice or frost from the windshield. See "Heated Windshield" later in this section.

Downloaded from www.Manualslib.com manuals search engine DEFOG: Press thl's button to divide the air between the
windshield and
the heater outlets. This is useful when
fog appears on the windshield or side glass due to
sudden rain or snowy conditions. This feature is not
available with the heated windshield option.
AUTO/ECON: Press this button to switch between
AUTO and ECON. The ECON setting attempts to keep
air at a selected temperature, however, it does not
remove humidity from the air. Use this setting in cold
or
cool weather to save fuel. The AUTO setting is used
when it's warm outside and you need
to cool the air in
order to maintain a selected temperature and blower
speed.
FAN SPEEDS: Press the button with the fan
symbol until AUTO is displayed on the screen. At this
setting, the fan speed
is automatically controlled. If it is
cold outside, the blower may not
run in the maximum
high
fan speed right away. The system checks the temperature of the engine
coolant to assure it is warm
enough to provide heat. When
the engine coolant is
wm, the controller allows the fan to gradually increase
to a higher speed. This prevents cold air from blowing
into the passenger compartment.
If you want the blower
fan at a high speed, press the up arrow button until you
see HI
on the display. If you want the fan speed to be
automatic, but
you like the fan speed to be higher than
the
AUTO setting, press the fan symbol button until HI
AUTO
is shown on the display. If you want the blower
fan at a
low speed, press the down mow button until
LO is shown on the display. If you want the fan speed to
run lower than the
AUTO setting, press the button until
AUTO LO is shown on the display.
9 DEFROST: Press this button to quickly remove
fog or frost from the windshield.
This setting sends most
of the airflow to the windshield with only a small
amount to the floor outlets.

Downloaded from www.Manualslib.com manuals search engine Electronic Solar Sensor
The sensor monitors the sun’s solar radiation and is
located
on top of the instrument panel near the
windshield. The
ECC system uses this information to
automatically
make the necessary temperature and
airflow adjustments to maintain your
comfort.
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.
Press the
AUTO/ECON button to assist in cooling air
and in maintaining proper airflow. Adjust the
temperature
to a comfortable setting by pressing the
blue button to cool your vehicle
and pressing the red
button to
warm your vehicle. Press the fan button arrows
up or down
to adjust the fan speed.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle’s engine speed and
power. This is normal because the system is designed to
cycle the compressor on and off to keep the desired
temperature.

rress the AUTOECON button to direct airflow out
of the floor outlets and to help save fuel. Adjust the
temperature, if necessary, by pressing the blue button
to decrease temperature and pressing the red button
to
increase temperature. Also remember to adjust the fan
speed by pressing the up or down arrow.
Outside air will be brought in and sent through the floor
outlets. The heater works best if you keep your windows
closed while using it.
Ventilation System
Your Cadillac'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 lever located
on each side
of the outlets downward.

Downloaded from www.Manualslib.com manuals search engine The system will go off after a four-minute heating cycle.
If you shift out of
PARK (P), the system will only cycle
for
two minutes. If you want it to cycle again, press the
button. It will
go on for two-minute cycles after that. If
the windshield has cleared before the cycle is over, you
can turn it off by pressing the button again.
Use the defroster feature
to clear fog from the
windshield as previously described.
There is a metal film in the windshield which will block
out some radio or microwave signals. Therefore, the
heated windshield will reduce the useful range of
devices such as garage door openers and radar detectors.
(In certain states, radar detectors are legal.)
Do not use the DE-ICE button if your vehicle has a
cracked windshield.
A crack will not allow the system to
function properly. Have the windshield repaired before
using the DE-ICE button again.
Defogging and Defrosting
On cool, humid days, use DEFOG to keep the
windshield and side windows clear. Use DEFROST to
remove
fog or ice from the windshield quickly in
extremely humid
or cold conditions.

Press the DEFOG or DE-ICE button and adjust the fan
speed by pressing the fan button up or down. If you use
DEFROST, adjust
the fan speed the same way. If you
select DEFROST from AUTO, the system will control
the
fan speed. The temperature will also need to be
adjusted to your comfort level. Press the blue button to
decrease the temperature and the red button to increase the temperature.
Note that recirculation is not available
in the defrost or
defog modes.
