speed, push the
“Lo” or “Hi” button until you see the “Auto Fan Lo Fan”
on the display.
When first starting your vehicle with a cold engine, the fan speed will
gradually increase as the temperature
of the engine coolant increases.
Defiost
To get fog or ice off the
windshield, push the
Defrost button.
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). The fan speed
operation is delayed if the engine is not at its normal operating
temperature.
Heated Windshield (Option)
Front De-Ice
Here’s how to use your heated windshield in cold weather to remove ice
or frost quickly:

2. Start your Cadillac and leave it in P (“Park”).

YOU will find the two warning lights about a hot engine on your Cadillac
instrument panel.
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

’ A CAUTION: I
An electric fan under the hood can start up even when the
engine
is not running and can injure you. Keep hands, clothing
and tools away from any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling, don’t do
anything else until it cools down.

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.
Dodbrun 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 Pied 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

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant Recovery Tank
If you haven’t found a problem yet, but the coolant level isn’t at or above
near
“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.)
1
A CAUTION: i
Jding only plain water to your cooling system can be
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.

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.
I
When the coolant in the coolant recovery tank is at or above near “FULL
COLD,” start your vehicle.
If the overheat warning continues, there’s one more thing you can try.
You can add the proper coolant mix directly to the radiator, but be sure
the cooling system is cool before you do it.
