P
c
:. ..; .. .. .. '... ,
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and
your driving patterns.
To see the display, press the
INFORMATION button several times until
XX OIL
LIFE LEFT appears. If you see 99% OIL LIFE LEFT,
99% of your current oil life remains.
The DIC may display a
CHECK OIL LEVEL message.
Always keep a written record of the mileage and date
when you changed your oil. For more information, see
the Cadillac Maintenance Schedule booklet.
If you see
CHECK OIL LEVEL, it means that you have less
than 10% of the oil life left and you'should consider
changing your engine oil. If you see
CHANGE
ENGINE OIL, it means the oil life is gone and you
should change the oil right away.
The system should indicate changing the oil between
3,000 miles (5 000 km) and 7,500 miles (12 500 km).
It may indicate changing the oil before 3,000 miles
(5 000 km) depending on your driving habits. If the
vehicle has been driven
7,500 miles (12 500 km) it
will indicate to change the oil.
If you drive in a dusty
area, you should change your oil every
3,000 miles
(5 000 km) or three months (whichever comes first)
unless the display indicates changing
it sooner. The
system doesn't check
how much oil you have, so
you'll still have to check for that. To see how, see
"Engine Oil" in
the Index.
When new oil is added, you'll need to reset the system.
To reset, display the Oil Life Indicator by pressing the
INFORMATION button. Then press and hold the RESET
button until the display shows 100 OIL LIFE LEFT.
Electronic Level Control
This feature keeps the rear of your vehicle level as the

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.
