through the system.
Turn the TEMP knob clockwise to
increase the temperature and counterclockwise
to
decrease the temperature. The outside temperature is
always displayed when your vehicle is running.
Modt :ton
Press this button to deliver air through the floor, middle
or windshield outlets. The system will stay
in the
selected mode until the
MODE button is pushed again.
Press the up or down arrow to cycle through the
available modes.
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
(16"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 lnaximum 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 (AC 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
airflow 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.

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.
With the ECC system, press the AUTOECON 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.
If you have the dual-zone system, press the AC button
to turn the system on and then select the proper MODE
to direct airflow. The system will cool and dehumidify
the air inside the vehicle. Also while in the AUTO
mode, the system will use recirculation as necessary to
cool the air. You may also need to adjust the interior
temperature. Turn the TEMP knob clockwise to increase
the temperature and counterclockwise to decrease
temperature. Adjust the fan speed as needed.
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. With
the ECC system, press 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.
If you have the dual-zone system, press the MODE
button to select heater. This will direct airflow out of the
floor outlets. Adjust the interior temperature to your
comfort level by turning the
TEMP knob clockwise to
increase temperature and counterclockwise to decrease
temperature. If the fan speed needs adjusting, press the
up or down arrow.
With each system, 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.

Keep the hood and front air inlet free of ice, snow
or any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.
When you enter a vehicle in cold weather, adjust
the fan to the highest speed for a few moments
before driving off. This helps clear the intake
outlets of snow and moisture, and reduces the
chance of fogging the inside of the windows.
Keep the air path under the front seats clear of
objects. This helps circulate air throughout your
vehicle.
I
Heated Windshield (Option)
The heated windshield will remove ice or frost in
cold weather.
1. Remove snow that is piled up on the windshield.
2. Start your Cadillac and leave it in PARK (P).
3. Press the DE-ICE button. A light will come on to
tell you it is working. Try not to use other electrical
equipment while the system is working. 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.

Downloaded from www.Manualslib.com manuals search engine Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could
be damaged. Avoid
making very sharp turns while trailering.
I
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees or other objects.
Avoid jerky
or sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and extra wiring. Check
with your Cadillac dealer. The green arrows on your
instrument panel will flash whenever you signal a turn
or lane change. Properly hooked
up, the trailer lamps
will also flash, telling other drivers you’re about to
turn,
change lanes or stop. When
towing
a trailer, the green arrows on your
instrument panel will flash for turns even if the bulbs on
the trailer are burned out. Thus, you
may think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear hefor-e you start
down a long or steep downgrade.
If you don’t shift
down,
you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) or less to reduce the
possibility
of engine and transaxle overheating.

You will find an ENGINE COOLANT HOT-IDLE
ENGINE message or a
STOP ENGINE ENGINE
OVERHEATED message
on the DIC. There is also an
engine temperature warning light on the instrument
panel. See “Engine Temperature Warning Light”
in the
Index.
Overhe 1 Engine Ootection Operating
Mode
Should a low coolant condition exist and the message
STOP ENGINE ENGINE OVERHEATED is displayed,
an overheat protection mode which alternates firing
groups
of four cylinders helps prevent engine damage.
This operating mode allows your vehicle to be driven
to a safe place in
an emergency; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
NOTICE:
After driving in the Overheated Engine
Protection Operating
Mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be
severely degraded. Change the oil and reset the
oil life indicator. See “Engine Oil, When to Change” in the Index.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by
your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there seem to be no leak, with the engine on, check to
see if the electric engine fans are running. If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.
How to Add Coolant to the Coolant Surge
Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the proper level
(2.5 inches (60 mm) below the
base
of the fill neck), add a 50/50 mixture of cleun
water (preferably distilled) and DEX-COOL TM
antifreeze at the coolant surge tank, but be sure the
cooling system, including the coolant surge tank
pressure cap, is cool before
you do it. (See “Engine
Coolant’’ in the Index for more information.)
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the coolant surge
tank pressure cap
-- even a little -- they can come
out at high speed. Never turn the cap when the
cooling system, including the coolant surge tank
pressure cap,
is hot. Wait for the cooling system
and coolant surge tank pressure cap to
cool if you
ever have to turn the pressure cap.

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, see “Engine Overheating”
in the Index.
A 50/50 mixture of water and the proper coolant for
your Cadillac will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else.
A special procedure is required for adding sealer; see the
Cadillac service manual.
(To order a service manual, see
“Service and Owner Publications” in the Index.)

Downloaded from www.Manualslib.com manuals search engine Adding Coolant
If you need more coolant, add the proper mix at the
surge tank, but only when the engine is cool.
I
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
~ ~~
When replacing the pressure cap, make sure it is tight.
Surge Tank Pressure Cap
1 NOTICE:
The surge tank cap is a 15 psi (105 kPaj
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows
on the cap
line up.
If the surge tank pressure cap needs to be replaced, a
General Motors cap
is recommended.
