receives an incorrect feedback from the system, an error code
will be set
in memory and a “SERVICE RIDE CONTROC’ message will display on
the Driver Information Center. If this message should appear, have your
vehicle serviced at your Cadillac dealer at your earliest convenience.
Oil Life Indicator
This feature lets you know when to change your engine oil. It’s based
upon the engine oil temperatures and your driving patterns.
To see the display, press the Information button several times until
“XXX
OIL LIFE LEFT” appears.
You’ll
see how much oil life you have left, as a percentage. So, if you see
“95 OIL LIFE LEFT,” for example, that means that the way you’re
driving your car,
95% of your current oil life is still left.
The Oil Life Indicator may say
to change the oil sooner than your
maintenance schedule. This can happen
if driving conditions, such as
short trips
in cold weather, cause shorter oil life. Always keep a written
record of the mileage and date when you last changed your oil. For more
information on when to change your oil, see the Cadillac Maintenance
Schedule Booklet.
If you
see “CHANGE OIL SOON,” it means that you have less than 10%
of your 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 (certainly within 200 more miles
[320 km]).

Downloaded from www.Manualslib.com manuals search engine The system probably will say to change the oil between 3000 miles
(5000 km) and 7500 miles (12500 km), but it may even say to change it
before
3000 under very severe conditions. It all depends on your driving
patterns. If it’s been
7500 miles (12500 km) it always says to change the oil.
There are
two things the system doesn’t do:
0 It can’t sense heavy dust in the places where you drive. If you drive in
a dusty area, you should change your oil every
3000 miles (5000 km)
or
3 months (whichever comes first), unless the display says to change
it even sooner than that.
It 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.
men You’ve Changed the Oil
When new oil is put in, you’ll need to reset your system. To do it, display
the “OIL LIFE INDEX” by pressing the INFORMATION button. Then
press and hold the RESET buttons until the display shows
“100 OIL
LIFE LEFT”
Electronic Level Control
This keeps your car level.
The ignition has to be “ON” for the level control to work. When you turn
the ignition off, you may hear the level control exhausting. The system
consists
of an electronic height sensor, a small electric air compressor,
and air adjustable shock absorbers mounted on the rear
of the vehicle.
If the system has a slight leak, the air compressor will run frequently for a
few seconds each time.
For
a massive air leak, the air compressor will stay on for approximately
7 minutes. You should see your dealer for service, but you can keep
driving your Cadillac.

In this section you’ll find out how to operate the comfort control systems
and audio systems offered
with your Cadillac. Be sure to read about the
particular system supplied
with your vehicle.
YOUR CADILLACAIR SYSTEM
Outside Air
The outside air always flows throggh your vehicle when it is moving. It
enters your vehicle through an inlet at the base
of the windshield. Keep
this area clear of debris. Even
if the vehicle is not moving, you can always
get outside air.
If you are traveling in the 60 F (16 C) AUTO setting, a
door
will close to stop most of the flow of outside air, recirculating only
the interior air to cool your vehicle.
Air Outlets
The air outlets are
located in the center
and at each side
of the
instrument panel. You
can adjust the
direction
of air flow by
moving the center
control levers or stop
the air
flow by moving
the lever located on
each side
of the outlets
downward.

-I
Your vehicle has strategically placed electronic sensors, that feed
information to the vehicle’s computer systems. Your vehicle can control
the ventilation, heating, and air conditioning automatically year round.
The outside temperature, inside temperature setting, fan speeds, and the
ECC selection are displayed
on a digital screen.
OFF: Nothing is on, but air will flow through your vehicle if you’re
moving. The system
will try to keep the air at the selected temperature,
but it might not be able to maintain it
if it’s hot, or cold, outside.
“OUTSIDE” Temperature: The outside temperature is always displayed
when your vehicle is running. You can change it from Celsius to
Fahrenheit by pushing the ENG/MET (English/Metric) button.

Downloaded from www.Manualslib.com manuals search engine Temperature
To select the
temperature
you want,
push the blue button
for a cooler setting and
the red button for a
warmer setting. The
temperature setting
will be displayed on
the digital screen.
You can select temperatures from
65’F (18°C) to 85°F (29’C). And, at
each end,
you may choose 60” F (16’C), for maximum cooling, and 90 ” F
(33 ’ C), for maximum heating. We recommend when first getting familiar
with your vehicle, select
75°F (24’C). You may find that your own
personal comfort requires a slightly higher or lower setting. Once you set
the temperature, the system will automatically maintain the
set
temperature.
ECON
With this setting it’s all automatic, but the air conditioning compressor
does not operate and it won’t remove humidity from the air. However,
the system will try to keep the air at the selected temperature. Use this
setting
in cold or cool weather to save fuel.
r
If it’s warm outside and you need to cool the air, use the “AUTO” setting.

Downloaded from www.Manualslib.com manuals search engine AUTO
With this setting, the air conditioning compressor cycles when needed to
cool the air and it’s all automatic. In cold weather when the system senses
- the need for heat, the air flow will be directed out the floor ducts. As the
interior temperature approaches the desired setting, the blower speed
will decrease and the air flow could be directed through the defroster and
floor ducts.
To maintain interior comfort, the air flow may move to the air
outlets and floor ducts (Bi-level). On bright sunny days
in cold weather,
the air
flow could even come out the A/C outlets to maintain comfort and
prevent stuffiness.

A/C Purge
- .. 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 ducts for a few seconds. That is
normal. This is to expel hot air in the air ducts.
As the air is cooled, the
__ flow 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.
Cold Weather Purge
-- On cold days when your system is first turned on, in either the AUTO or
ECON setting and the fan setting is not on “HI”, a small amount of air
will flow through the defroster duct while the system is waiting for the
breath from fogging your windshield.

Downloaded from www.Manualslib.com manuals search engine Fan Speeds
Push the (symbol)
button until “AUTO” is
displayed on the
screen.
At this setting, the fan speed
is controlled automatically.
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 coolant to
assure it is warm enough to provide heat. When the coolant
is warm, the
controllers will allow the fan to ramp up to a higher speed. This prevents
cold air from blowing into the passenger compartment.
If you want the blower fan to run only at a fixed high speed, push the
(upper) 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.AUT0 setting, just push the buttons until “HI/AUTO”
is shown on the display.
If you want the blower to run only at a fixed
low speed, push the (low)
button until “LO” is shown on the display.
If you want the fan speed to run lower than the “AUTO” setting, push the
button until “AUTO
LO” is shown on the display.
DEFROSTER
--
Push this button to
remove fog or frost
from the windshield.
This setting sends most
of the air flow to the windshield with only a small
amount to the floor outlets.
The fan speed
will work automatically to maintain your requested interior
temperature.
If you need more air to your windshield, you should select a
higher fan speed.
In some cold start conditions, the AUTO fan speed may be limited until
the system warms up. This is normal
to prevent windshield fogging.
It will help a lot
if you first clear any ice and snow from the hood and the
air inlet (it’s between the hood and the windshield).

Downloaded from www.Manualslib.com manuals search engine REAR WINDOW DEFOGGER
Push this button to turn
on the rear defogger.
With it, your rear
window and both
outside rearview
mirrors are heated.
The system will automatically shut
off after 10 minutes. If further
defrosting is desired, simply push the button again.
NOTICE:
Scraping the inside of your rear window could cut and damage
the heating grids. Your warranty would not cover this damage.
And don’t put decals there; you might have to scrape them
off.
