1-1 Push this button to
remove fog or frost
from the windshield.
This setting sends most of the air flow to the windshield with only a small
amount to the floor outlets. In some cold start conditions, the
“AUTO”
blower fan speed may be limited until the cooling system warms up. This
is normal to prevent windshield fogging.
The .fan speed will work automatically to maintain your requested interior
temperature. If
you need more air to your windshield, you should select a
higher fan speed.
It will help a lot if you first clear any ice and snow from the hood and the
air inlet (it’s between the hood and the windshield).
REAR DEFOGGER
I
Push this button to turn
on the rear defogger.
With it, your rear window and both outside rearview mirrors are heated.
The system will automatically shut off after
10 minutes. If further
defrosting is desired, simply push the button again.
NOTICE:
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.

Front De-Ice
Here’s how to use your heated windshield in cold weather to remove ice
or frost quickly:
1. If any snow is piled up on the windshield, brush it away.
2. Start your Cadillac and leave it in P (“Park”).
‘. .
n.
3. Push the switch. A light will come on to tell you it is working.
4. Try not to use other electrical equipment while the system is working.
The system will go
off after a four minute heating cycle. If you shift out of
“P” (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 by 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.)

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
66 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 how to do it:
Apply your regular brakes, but do not shift into “P” (Park).
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the regular brakes until
0 Reapply the regular brakes. Then shift into “P” (Park) firmly and
the
chocks absorb the load.
apply your parking brakes.
Release the regular brakes.
when You Are Ready to Leave A@er Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
0 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.
4. Stop and have someone pick up and store the chocks.

Engine damage from running your engine without coolant isn’t
covered
by your warranty.
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 visible
inside the surge tank add a
50/50 mixture of clean water (preferably
distilled) and a proper antifreeze at the coolant surge tank, but be sure
the cooling system, including the coolant surge tank pressure cap, is cool
before you do it.
(See “Engine Coolant” in the Index for more
information about the proper coolant mix.)
If it isn’t, you may have a leak in the radiator fiose, heater hoses, radiator, -
water pump or somewhere else in the cooling system. -

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 coolant for your Cadillac will:
Give freezing protection down to -34OF (-37 C).
0 Give boiling protection up to 262OF (128OC).
0 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 change.
If you use this mixture, you don’t need to add anything else.

1 NOTICE:
Your 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 with the overflow tube on the radiator filler neck.
i
When you replace your surge tank pressure cap, an AC@ cap is
recommended.
THERMOSTAT
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.
When you replace your thermostat, an
AC@ thermostat is recommended.
