This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at a lower speed for increased
maneuverability and parking ease. As your vehicle speed increases, the
steering effort is also increased proportionately. At highway speeds the
amount
of steering effort is increased to provide a manual like steering
feel for maximum control and enhanced vehicle stability.
Road Sensing Suspension
The Road Sensing Suspension automatically controls the ride of your
vehicle. The system controls damping forces in the
shock absorbers and
struts in response to various road and driving conditions. The system is
capable
of making these changes within milli-seconds.
The Road Sensing Suspension controller is a computer used to control
and monitor the system. The computer receives inputs from vertical
acceleration sensors, wheel to body position sensors, vehicle speed
sensor, lift and dive signals, and determines optimum strut valving or
(suspension stiffness) for your current operating conditions. The
computer also receives feedback from the various components to
determine proper system operation. If the computer receives an incorrect
feedback from the system, an error code will be set in memory and a
“SERVICE
RIDE CONTROL’ 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.

Downloaded from www.Manualslib.com manuals search engine Oil Life Indicator s_
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 “XX 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]) .
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.
151

Downloaded from www.Manualslib.com manuals search engine There are two things the system doesn’t do:
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.
0 It doesn’t check how much oil you have, so you’ll still have to check
for that. To see how, see Index under “Engine Oil.”
When 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 rear position 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, though.

COMFORT CONTROLS AND AUDIO SYSTEMS
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 CXDILLACAIR SYSTEM
Outside Air
The outside air always flows through 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 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 adiust the
-;".".,,rx???r c(xm- .. direct:on 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.

Downloaded from www.Manualslib.com manuals search engine Electronic Climate Control (ECC)
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 OC), for maximum heating. We recommend when fiit getting familiar
with your vehicle, select 75
OF (24OC). 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.
If it’s warm outside and you need to cool the air, use the next choice.
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
engine coolant to warm up enough to provide heat. This prevents your
breath from fogging your windshield.
As the coolant warms up, the
blower fan speed will gradually increase and air will flow from the heater
outlets, with some air bleed to the windshield to prevent fogging under
most normal conditions.
Manually Recirculate Inside Air
There may be times, when you don’t want air from the outside. To
recirculate the air from the inside only,
just set the temperature to 60°F
(16°C) and adjust your fan speed, if the air quantity is too high.
DEFOG
Push this button to divide the air between the windshield and the heater
ducts. This
is useful when fog appears on the windshield or side glass due
to a sudden rain or snowy conditions.
156

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
controller 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 AUTO 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.
