1996 CADILLAC SEVILLE heater

Downloaded from www.Manualslib.com manuals search engine Engine Coolant Heater (Option) (Canada
Only)
In very cold weather, 0°F (- I 8 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.
To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, 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.

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.
Automatic Transaxle Operation
The automatic transaxle may have either a shift lever
located on the steering column or on the console.
between the seats.
There are several different
positions for the shift lever.

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
vour vehicle with the fan setting on
HI, it will skip the
i/~ 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 airflow
to
the windshield to prevent fogging under most normal
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 moae.
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 this 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
ox 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
warm, 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 arrow 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.
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.

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.

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. 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.
The front outlets
are located in the center and at each
side
of the instrument panel. You can adjust the
direction
of aifflow by moving the center control levers
or
you can stop the airflow by moving the lever located
on each side
of the outlets downward.

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.
The direction
of airflow for the rear seats can also be
adjusted. Move the
FAN lever to adjust the blower speed
from
LO to HI. Move the VENT lever to direct airflow
toward the upper or floor outlets.
