1996 CADILLAC DEVILLE air condition

Downloaded from www.Manualslib.com manuals search engine Heating
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.

....,.
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.

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.
Defogging and Defrosting
On cool, humid days, use DEFOG 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.

Press the DEFOG or DE-ICE 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.
Note that recirculation is not available
in the defrost or
defog modes.

Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety, you’ll\
want to slow down and adjust your driving
to these
conditions.
It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction,
try
your best to avoid sudden steering, acceleration or
braking (including engine braking by shifting
to a lower
gear).
Any sudden changes could cause the tires to
slide.
You may not realize the surface is slippery until
your vehicle is skidding. Learn to recognize warning
clues
-- such as enough water, ice or packed snow on
the road
to make a “mirrored surface” -- and slow
down when you have any doubt.
Remember: Any anti-lock brake system
(ABS) helps
avoid only the braking skid.
Driving at Night
Night driving is more dangerous than day driving. One
reason is that some drivers
are likely to be impaired -- by
alcohol or
drugs, with night vision problems or by fatigue.

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.
Overheated Engine Protection Operating
Mode
Y
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.
I 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.

If you get the overheat warning but see or hear no
steam, the problem may not
be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
0 Idle for long periods in traffic.
Tow a trailer.
c
c
If you get the overheat warning with no sign of steam,
try this for
a minute or so:
1. Turn off your air conditioner.
2. Dial temperature control to the highest heat setting and open the window, as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- OVERDRIVE (a) or THIRD (3).
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes,
If the warning doesn’t come back on, you can drive
nonnally.
If the warning continues, pull over, stop
and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two
or three minutes while you’re parked, to see if
the warning stops.
But then, if you still have the
warning,
turn off the engine and get everyone out of the
vehicle
until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously in
this section.
You may decide not to lift the hood but to get &mice
help right away.

I A CAUTION:
You can be injured and your vehicle could be
damaged if
you try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before you attempt any vehicle maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English’ and “metric”
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Fuel
Use premiurn unleaded gasoline rated at 91 octane or
higher.
At a minimum, it should meet specifications ASTM
D4814 in the United States and CGSB 3.5-M93 in Canada.
Improved gasoline specifications have been developed by
the American Automobile Manufacturers Association
(AAMA) for better vehicle performance and engine
protection. Gasolines meeting the
AAMA specification could provide improved driveability and emission control
system protection compared to other gasolines.
Be sure the posted octane for premium is at least
91. If
the octane is less than
91, you may get a heavy knocking
noise when you drive.
(In an emergency, you may be
able to use a lower octane
-- as low as 87 -- if heavy
knocking does not occur.) If you’re using
91 or higher
octane unleaded gasoline and you still hear heavy
knocking, your engine needs service.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it is designed to operate on fuels that meet California
specifications. If such fuels are not available
in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may
turn on and/or your vehicle
may fail a smog-check test. If this occurs, return to your
authorized Cadillac dealer for diagnosis to determine the
cause
of failure. In the event it is determined that the
cause of the condition is the type of fuels used, repairs
may not be covered by your warranty.

Downloaded from www.Manualslib.com manuals search engine I NOTICE:
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied
or lightly
applied. This does not mean something is wrong with
your brakes.
Free movement of brake calipers and proprely torqued
wheel nuts are necessary
to help prevent brake
pulsation. When tires are rotated, inspect brake calipers
for movement, brake pads for wear, and evenly torque wheel nuts in the proper sequence to
GM Specifications.
Brake linings should always
be replaced as complete
axle sets.
Brake Pedal Travel Brake Adjustment
Every time you apply the brakes, with
or without the
vehicle moving,
your brakes adjust for wear.
Replacing Brake System Parts
The braking system on a modem vehicle is complex.
Its many parts have to
be of top quality and work well
together if the vehicle
is to have really good braking.
Vehicles
we design and test have top-quality GM brake
parts in them, as your Cadillac does when it is new.
When you replace
parts of your braking system -- for
example, when your brake linings wear down and you
have to have new ones put in
-- be sure you get new
genuine
GM replacement parts. If you don’t, your
brakes may no longer work properly. For example, if
someone puts in brake linings that are wrong for your
vehicle, the balance between your front and rear brakes
can change -- for the worse. The braking performance
you’ve come to expect can change in many other ways if
someone puts in the wrong replacement brake
parts.
--
See your dealer if the brake pedal does not return to
normal height,
or if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.

Downloaded from www.Manualslib.com manuals search engine Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded.
If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced.
If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes
be repaired). See your
Cadillac dealer if
any of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts. This way, you will
be sure to have the
right wheel, wheel bolts and wheel nuts for your Cadillac
model.
A CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose
air and make you
lose control. You could have
a collision in which
you or others could be injured.
Always use
the correct wheel, wheel bolts and wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer/odometer
calibration, headlamp aim, bumper height, vehicle
ground clearance and tire
or tire chain clearance
to
the body and chassis.
See “Changing
a Flat Tire” in the Index for
more information.
