When you decide it’s safe to lift the hood, here’s what you’ll see:
Coolant recovery tank
7 Radiator pressure cap
7 Electric engine fans
’ 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.

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.

Rust or dirt on the wheel, or on the parts to which it is fastened,
can make the wheel nuts become loose after a time. The wheel
could come off' and cause an accident. When you change a wheel,
remove
any rust or dirt from the places where the wheel
attaches
to the vehicte. In a emergency, you could use a cloth or
a paper towel to do this; but be sure to use a scraper or wipe
brush later, if you need to, to get all the rust'or dirt off.
-I
Remove any rust or dirt from the wheel bolts, mounting surfaces or spare
wheel. Place the spare on the wheel mounting surface.

If you plan 6n driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t
work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can
corrode, and your engine
oil can deteriorate quickly. Your vehicle’s
oxygen sensor
will be damaged. All of that means costly repairs that
wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell
us
where you’re going and give your Vehicle Identification Number (VIN).

A CAUTION:
Things that burn can get on hot engine parts and start a fire.
These include liquids like gasoline, oil, coolant, brake fluid,
windshield washer and other fluids, and plastic or rubber. You
or others could be burned. Be careful not to drop or spill things
that will burn onto
a hot engine.
Before closing the hood,
be sure all the filler caps are on properly.
Then just pull the
hood down until it’s about 15 inches (38 cm) from
closing. Then close it firmly.

It's a good idea to check your engine oil every time you get fuel. In order
to get an accurate reading, the oil must be warm and the vehicle must be
on level ground.
Turn
off the engine and give the oil a few minutes to drain back into the
oil pan. If you don't, the oil dipstick might not show the actual level.
,
L and clean it with a
paper towel
or cloth, ' then push it back in all
* I the way. Remove it
again, keeping the tip
lower.

Downloaded from www.Manualslib.com manuals search engine When to Add Oil: If
the oil is at or below
the ADD line, then
you’ll need
to add
some oil. But you must
use
the right kind. This
section explains what
kind
of oil to use. For
crankcase capacity, see
“Capacities and
Specifications” in the
Index.

To remove, turn the oil
fill cap to the left.
Just fill it enough to put the level somewhere
in the proper operating
range. Push
the dipstick all the way back in when you’re through.
What Kind of Oil to Use:
Look for three things:
0 SG
“SG” must be on the oil container, either by itself or combined with
other quality designations, such as “SG/CC,” “SG/CD,” “SF,SG,CC,”
etc. These letters show American Petroleum Institute
(MI) levels of
quality.

FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURL RANGE.
I

Downloaded from www.Manualslib.com manuals search engine SAE 1OW-30
As shown in the viscosity chart, SAE 1OW-30 is best for your vehicle.
However, you can use
SAE 5W-30 if it’s going to be colder than 60°F
(16°C) before your next oil change. When it’s very cold, below
O°F
(-18”C), you should use SAE 5W-30.
These numbers
on an oil container show its viscosity, or thickness. Do not
use other viscosity oils such as SAE 1OW-40 or SAE
20W-50.
Energy Conserving I1
Oils with these words on the container will help you save fuel.
This doughnut-shaped logo (symbol) is used on most
oil containers to
help you select the correct
oil.
You should look for this on the oil container, and use only those oils that
display the logo.

requirements for your vehicle.
Engine Oil Additives: Don’t add anything to your oil. Your Cadillac
dealer is ready to advise if you think something should be added.
When to Change Engine Oil: Your vehicle is equipped with an Engine Oil
Life Index (EOLI) feature. Oil change intervals are determined by the
EOLI and will usually fall at, or between, the two recommended
alternative intervals of 3,000 miles
(5,000 kilometers) and 7,500 miles
(12,500 kilometers), but could be shorter than 3,000 miles (5,000
kilometers) under some very severe driving conditions shown in Schedule
I. The system will also indicate the need for an oil change if 7,500 miles
(12,500 kilometers) has been driven.
Engine oil life remaining is displayed through the Fuel Data center and as
a
“CHANGE OIL SOON” light. The Fuel Data center display includes a
number between
0 and 100. This is the percentage of oil life
REMAINING based on driving conditions and mileage driven since the
last time the oil life indicator was reset.
The EOLI will not detect excessively dusty conditions or engine
malfunctions which may effect the
oil. If you drive in dusty areas, change
the engine
oil after every 3,000 miles (5,000 kilometers) or 3 months
(whichever comes first), unless instructed to
do so sooner by the EOLI.
