The Driver Information Center will display either ENGINE COOLANT
HOT-IDLE ENGINE or
STOP ENGINE ENGINE OVERHEATING.
In addition you will find the warning light about a hot engine on your
instrument panel on Canadian vehicles.
Overheated Engine Protection Operating Mode
Should a low coolant condition exist and the message STOP ENGINE
ENGINE OVERHEATING 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.
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:
0 Climb a long hili on a hot day.
0 Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
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 wh.ile driving
-- AUTOMATIC OVERDRIVE (@) 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 normally.
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 service help right away.

A CAUTION:
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 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.
NOTICE:
In cold weather, water can freeze and crack the engine, radiator,
heater core
and other parts. So use the recommended coolant.
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.

Downloaded from www.Manualslib.com manuals search engine What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your
skin and could even cause cancer? Don't let used oil
stay
on your skin for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash
or properly throw away clothing or
rags containing used cngine
oil. (See the manufacturer's warnings about
the use and disposal of oil products.)
Used
oil can be a real threat to the environment. If you change your own oil,
be sure to drain all free-flowing oil from the filter before disposal. Don't ever
dispose
of oil by putting it in the trash, pouring it on the ground, into sewers,
or into streams or bodies
of water. Instead, recycle it by taking it to a place
that collects
used oil. If you have a problem properly disposing of your used
oil, ask your dealer, a service station or a local recycling center for help.
AIR CLEANER
11
A CAUTION:
Operating the engine with the air cleaner off can cause you or
others
to be burned. The air cleaner not only cleans the air, it
stops flame if the engine backfires. If it isn't there, and the
engine backfires, you could be burned. Don't drive with it off,
and be careful working on the engine with the air cleaner off.

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 coolant for your Cadillac
will:
Give freezing protection down to -34’F (-37OC).
0 Give boiling protection up to 262’F (128OC).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 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 1825M,” which won’t damage
aluminum parts. You can also use
a recycled coolant conforming to GM
Specification 1825M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant flush and
refill. If you use this
mixture, you don’t need to add anything else.

c
When you do need brake fluid, use only DOT-3 brake fluid -- such as
Delco Supreme
ll@ (GM Part No. 1052535). Use new brake fluid from a
sealed container only, and always clean the brake fluid reservoir cap
before removing it.
NOTICE:
e Don’t let someone put in the wrong kind of fluid. For
example, just a few drops of mineral-based oil, such
as
engine oil, in your brake system can damage brake system
parts
so badly that they’ll have to be replaced.
0 Brake fluid can damage paint, so be careful not to spill brake
fluid
on your vehicle. If you do, wash it off immediately. See
‘!Appearance Care” in the Index.
Brake Wear
Your Cadillac has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make a high-pitched
warning sound when the brake pads are worn and new pads are needed.
The sound may come and
go or be heard all the time your vehicle is
moving (except when you are pushing on the brake pedal firmly).
