heating CADILLAC SEVILLE 1997 4.G User Guide

Downloaded from www.Manualslib.com manuals search engine This section tells you how to make your air system work
for
you. Your Electronic Climate Control (ECC) system
uses ozone-friendly
R- 134a refrigerant.
With the
ECC system. you can control the heating,
cooling and ventilation in your Cadillac. Your vehicle
also has a flow-through ventilation system described
later
in this section. The
button with the fan symbol adjusts the fan speed.
Press the up arrow to increase fan speed and the down
arrow to decrease fan speed.
The TEMPIAUTO knob adjusts the air temperature
coming through the system. Turn the TEMP/AUTO
knob clockwise to increase the temperature and
counterclockwise to decrease the temperature. Press
the
TEMWAUTO knob to put the system in the
automatic mode.
With this dual-zone feature, the right front passenger can
control the temperature
of air for hidher own zone. The
passenger can select a four degree warmer or cooler
temperature from the driver's setting.
To turn the system
on, press the PASSTEMP button. Press the up arrow to
increase the temperature and press the down arrow to
decrease
the climate setting. Pressing the OFF button
will
turn off the dual-zone function.

Downloaded from www.Manualslib.com manuals search engine To-find your comfort zone, start with the 75°F (24°C)
setting and allow about 20 minutes for the system to
regulate. Turn the
TEMP/AUTO knob to adjust the
temperature if necessary.
If you choose 60°F ( 1 6"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 maximum setting will not cause
the system
to heat or cool any faster.
With
the: automatic 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 air conditioning 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 from the air outlets. As the air
is cooled,
the airflow will move through the air conditioning
outlets. If you start your vehicle with the fan setting on
HI, it will skip the air conditioning 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 automatic operation when the ignition is shut off and
then turned back
on.

The lines you see on the
rear window
warm the
glass. Press this button
to
turn on the rear defogger.
With it, the rear window
and both outside rearview
mirrors are heated.
The system will automatically shut off after
10 minutes.
If further defogging is desired, press the button again.
Do not attach a temporary vehicle license, tape or decals
across the defogger gd
on the rear window.
I NOTICE:
c
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.
Some heating and cooling
controls can be adjusted at
the steering wheel. Other
touch controls operate some
audio controls. See "Audio
Steering Wheel Controls"
later in this section.

Hold the bottom of the steering wheel with one hand.
Then,
to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up
slowly and, if
possible, have someone guide you.
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or 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
instrulnent panel will flash for turns even if the bulbs on
the trailer are burned
out. Thus, you may think drivers NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with t,he
vehicle. Your vehicle could be damaged. Avoid

important to check occasionally to be sure the trailer
bulbs are still working.
making very sharp turns while trailering.
Reduce speed and shift to a lower gear before you start
When you’re turning with
a trailer, make wider turns down a long or steep downgrade. If you don’t shift
than normal.
Do this so your trailer won’t strike soft down, you might have to use your brakes so much that

or other objects. they would get hot and no longer work well.
Avoid jerky or sudden maneuvers. Signal weil
in advance. On

shift down and reduce your
speed to around
45 mph (70 km/h) or less to reduce the
possibility
of engine and transaxle overheating.

Downloaded from www.Manualslib.com manuals search engine If it isn’t, the coolant level should be indicated by a
CHECK COOLANT LEVEL message on the Driver
Information Center.
If it is, 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.
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 seems 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.

The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant
is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX-COOL" extended
life coolant.
8
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 DEX-COOL"
coolant will:
0 Give freezing protection down to -34°F (-37°C).
c
F
Give boiling protection up to 265°F (129°C).
0 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 only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@' 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. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered
by your new vehicle warranty.
Use a mixture of one-half cEean wccfer (preferably
distilled) and one-half DEX-COOL'" coolant which
won't damage aluminum parts.
If you use this mixture,
you don't need to add anything else.

If you need
more coolant, add the proper DEX-COOL@
coolant mixture at the surge tank, but only when the
engine .is cool.
I 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.
When replacing the pressure cap, make sure it is tight.
I NOTICE:
~~~~~~~~~~ ~
The surge tank cap is a 15 psi (105 kPa)
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.
Engine coolant temperature
is controlled by a thermostat
in
the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
If your thermostat needs to be replaced, a General
Motors thermostat
is recommended.

‘Zoading Your Vehicle”
in the Index.
0 Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
CAUTION: (Continued)
CAUTION: (Continued)
0 Overinflated tires are more likely to be
cut, punctured
or broken by a sudden
impact
-- such as when you hit a pothole.
