1998 CADILLAC DEVILLE heater

Downloaded from www.Manualslib.com manuals search engine Ventilation System
Your vehicle'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 direction
of airflow to the rear seats can be adjusted
if you have the optional full console (DeVille Concours
Only). Move the fan lever to adjust the blower speed
from LO to
HI. Motre the vent lever to direct the airflow.
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 aifflow by moving the lever located
on each side
of the outlets downward.

~ Ventilation Tips
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.
of objects. This helps circulate
air throughout
your vehicle.
Keep the air path under the front seats clear
Defogging and Defrosting
On cool, humid days, use DEFOG (digital cluster
climate control panel only) to keep the windshield
and side windows clear. Use DEFROST to remove fog or ice from the windshield quickly in extremely humid
or cold conditions.
With the digital cluster climate control panel, press
the DEFOG button and adjust the fan speed by pressing the fan button up or down.
If you use DEFROST,
adjust the fan speed the same way.
If you select
DEFROST from AUTO, the system will control the
fan speed. The temperature will also need to be
adjusted to your comfort level. Press the blue button
to decrease the temperature and the red button
to
increase the temperature. If your vehicle has a climate control panel (which
is
standard with the analog cluster). If you select
DEFROST, adjust the fan speed by pressing the fan
button up or down. If you select DEFROST from
AUTO, the system will control the fan speed. The
temperature also needs to be adjusted by turning the
TEMP/AUTO knob.
Note that recirculation is not available in the defiost
or defog modes.
Rear Window Defogger
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 grid on the rear window.

Downloaded from www.Manualslib.com manuals search engine 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 a while.
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.

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found
on the driver's door tells you the proper size,
speed rating and recommended inflation pressures for
the tires on your vehicle. It also gives you important
information about the number of people that can be in
your vehicle and the total weight that you can carry.
This weight is called the Vehicle Capacity Weight and
includes the weight
of all occupants, cargo and all

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.
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.
I 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 cooling fans are running. If the
engine is overheating, both fans should be running..
If
they aren’t, your vehicle needs service.

get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a 50/50 mixture of clean water and
DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant. 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.
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.

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.
B
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).
0 Give boiling protection up to 265 “F ( 129 O C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 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.

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clean water (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.
I
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system
is set for the proper coolant
mixture. With plain water or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a
50/50 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty.
Too much water in the mixture can
freeze and crack the engine, radiator, heater core
and other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
