NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment; check
with your dealer. If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.
Engine Coolant Heater (Option)
(Canada
Only)
In very cold weather, 0°F (- 18 O C) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged
in a minimum of
four hours prior to starting your vehicle.
2-17

Downloaded from www.Manualslib.com manuals search engine To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
.3. Plug it into a nonnal, grounded 110-volt AC outlet.
I A CAUTION:
Plugging the cord into an ungrounded outlet
could cause
an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into
a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.
4. After you’ve used the coolant heater, be sure to store
the cord as it was before to keep it away
from moving
engine parts. If you don’t, it could be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind
of oil you have and some other things. Instead of
trying
to list everything here, we ask that you contact
your Cadillac dealer in the area where you’ll be parking
your vehicle.
The dealer can give you the best advice for
that particular area.

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.

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.
.I . .
....,.
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.

c
The direction of airflow to the rear seats can also be
adjusted. Move the center lever to direct airflow toward
the upper or floor outlets. To direct aifflow from side to
side, move the lever located in the center
of each vent to
the right or left.
e 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 ducts 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.
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.

Run your engine only as long as you must. This saves
fuel. When you
run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel
for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly
for signaling later on
with your headlamps. Let the heater run for awhile.
Then, shut the engine off
and close the window almost
all the way
to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as
you can. To help keep warm, you can get
out of
the vehicle and do some fairly vigorous exercises
every half hour
or so until help comes.

The coolant level should be indicated by a CHECK
COOLANT LEVEL message on the Driver Information
Center.
If it isn't, you may have a leak in the radiator
hoses, heater
hoses, radiator, water pump or somewhere
else in the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them.
If you
do, you can be burned.
Don't run the engine if there
is a leak. If you run
the engine,
it could lose all coolant. That could
cause an engine fire, and
you could be burned.
Get
any leak fixed before you drive the vehicle.
5-19

Downloaded from www.Manualslib.com manuals search engine NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
A CAUTION:
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.
A
1. You can remove the coolant surge tank pressure
cap when
the cooling system, including the coolant
surge tank pressure cap and upper radiator hose,
is no longer hot.
Turn the pressure cap slowly
counterclockwise until it first stops. (Don't press
down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is
still some pressure left.

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your vehicle for
5 years or 100,000 miles (166 0o0 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 O C).
Give boiling protection up to 265 “F (129 “C).
Protect against rust and corrosion.
0 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 TM (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.)
