Downloaded from www.Manualslib.com manuals search engine Electronic Climate Control (ECC)
Your vehicle has strategicaly placed electronic sensors, that feed
information to the vehicle’s computer systems. Your vehicle can control
the ventilation, heating, and air conditioning automatically year round.
The outside temperature, inside temperature setting, fan speeds, and the
ECC selection are displayed on a digital screen. I
OFF: Nothing is on, but air will flow through your vehicle if you’re
moving. The system will try to keep the air at the selected temperature,
but it might not
be able to maintain it if it’s hot, or cold, outside.
“OUTSIDE” Temperature: The outside temperature is always displayed
when your vehicle is running. You can change it from Celsius
to
Fahrenheit by pushing the ENG/MET(English/Metric) button.

To select the
temperature you want,
push the blue button
for a cooler setting and
the red button for a
warmer setting. The
temperature setting
will be displayed on
the digital screen.
You can select temperatures from 65OF (18OC) to
85°F (69OC). And, at
each end, you may choose 60"
F (16OC), for maximum cooling, and 90°F
(33OC), for maximum heating.We recommend when first getting familiar
with your vehicle, select 75OF (24OC). You may find that your own
personal comfort requires a slightly higher or lower setting. Once you set
the temperature, the system
will automatically maintain the set
temperature.
ECON
With this setting it's all automatic, but the air conditioning compressor \
does not operate and it won't remove
humidity from the air. However,
the system
will try to keep the air at the selected temperature. Use this
setting
in cold or cool weather to save fuel.
If it's warm outside and you need to cool the air, use the next choice.
AUTO
With this setting, the air conditioning compressor runs and it's all
automatic. In cold weather when the system senses the need for\
heat, the
air flow
will be directed out the floor ducts. As the interior temperature
approaches the desired setting, the blower speed
will decrease and the air
flow could be directed through the defroster and floor ducts.
To maintain
interior comfort, the air flow may move to the air outlets and floor ducts
(Bi-level). On bright sunny days in cold weather, the air flow could even
come out the A/C outlets to maintain comfort.

The system will go
off after a four minute heating cycle. If you shift out of
“P7’ (Park), the system will only cycle for two minutes. If you want it to
cycle again, push the switch. It will go on
for two minute cycles after that.
If it has cleared your windshield before the cycle is over, you can turn it
off try just pushing the switch again.
Use
the defroster to clear the windshield. In warm weather the heated
windshield system helps keep the vehicle’s interior cool by blocking much
of the sun’s heat producing radiation. The system’s solar control
properties also help reduce interior fading.
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.)
SOUND SYSTEMS
Your Delcoa sound system has been designed to operate easily and give
years
of listening pleasure. But you will get the most enjoyment out of it if
you acquaint yourself with it first. Find out what your Delcos system can
do and how to operate
all its controls, to be sure you’re getting the most
out
of the advanced engineering that went into it.
FM Stereo
FM stereo will give you the best sound. But FM signals will reach only
about
10 to 40 miles (16 to 65 km). And, tall buildings or hills can
interfere with
FM signals, causing the sound to come and go.
The range
for most AM stations is greater than for FM, especially at
night.
The longer range, however, can cause stations to interfere with
each other.
AM can pick up noise from things like storms and power
lines.
Try reducing the treble to reduce this noise if you ever get it.

Reduce speed and shift to a lower gear before you start down a long or
steep downgrade. If you don’t shift down,
you might have to use your
brakes
so much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed to around
45
mph (70 km/h) or less to reduce the possibility of engine and transaxle
overheating.
If your trailer weighs more than 1,000 pounds (450 Kg) and you have an
automatic transaxle with Overdrive, you may want to drive
in “3” instead
of Overdrive
Parking on Hills
You really should not park your vehicle, with a trailer attached, on a hill.
If something goes wrong, your rig could start to move. People can be
injured, and both your vehicle and the trailer can be damaged.
But if
you ever have to park your rig on a hill, here’s bow to do it:
1. Apply your regular brakes, but don’t shift into “P” (Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until
the chocks absorb the load.
4. Reapply the regular brakes. Then shift into “P” (Park) firmly and
apply your parking brake.
5. Release the regular brakes.
When You Are Ready to Leave Afler Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
c
4. Stop and have someone pick up and store the chocks.

You will find the warning light about a hot engine on your Cadillac
instrument panel (Export
Only).
The driver information will display either “ENGINE COOLANT HOT
IDLE ENGINE” or “STOP ENGINE ENGINE OVERHEATING.”
If Steam Is Coming From Your Engine:
A CAUTION
Steam from an overheated engine can burn you badly, even if
you just open the hood. Stay
away from the engine if you see or
hear steam coming from it. Just turn it off and get everyone
away from the vehicle until
it cools down. Wait until there is no
sign of steam or coolant before opening the hood.
If you keep driving when your engine is overheated, the liquids
in it can catch fire. You or others could be badly burned. Stop
your engine
if it overheats, and get out of the vehicle until the
engine
is cool.

may have a
leak in the radiator hoses, heater hoses, radiator, water pump
or somewhere else
in the cooling system.
I
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.
If there seems to be no leak, 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.

How to Add Coolant to the Coolant Surge Tank
If you haven’t found a problem yet, but the coolant level isn’t at or above
“FULL COLD,” add a 50/50 mixture of clean water (preferably distilled)
and a proper antifreeze at
the coolant recovery tank. (See “Engine
Coolant”
in the Index for more information about the proper coolant
mix.)
A CAUTION
Adding only plain water to your cooling system can De
dangerous. Plain water, or some other liquid like alcohol, can
boil before the proper coolant mix will.
Your vehicle’s coolant
warning system is set
for the proper coolant mix. With plain
water
or the wrong mix, 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 mix of clean
water and
a proper antifreeze.

How To Reset Transaxle Fluid Change Indicator: 4.6L (Northstar)
Your vehicle is equipped with a transaxle fluid change indicator.
A
“CHANGE TRANS FLUID” message will display on the Information
Center
when the power train computer determines that the transaxle
fluid needs to be changed or at each 100,000 miles
(160,000 km) interval,
whichever occurs first. When this message appears, change the t\
ransaxle
fluid and reset the transaxle fluid life indicator
as follows:
Turn the key “ON” with the engine stopped.
Press and hold the “OFF” and “REAR DEFOG” buttons on the
climate control simultaneously
until the “TRANS FLUID RESET”
message appears
in the Information Center (between 5 and 20
seconds).
ENGINE COOLANT
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.
The proper coo’ It for
your Cadillac will:
Give freezing protection down to -34°F (-37’C) .
Give boiling protection up to 262 ” F (128 ” C) .
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should.
What to Use:
Use a mixture of one-half clean water (preferably distilled) and one\
-half
antifreeze that meets
“GM Specification 1825-M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to
GM
Specification 1825-M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant c\
hange.
If you use these, you don’t need to add anything else.
