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. -

Although the compact spare was fully inflated when your vehicle was
new, it can lose air after a time. Check the inflation pressure regularly. It
should be
60 psi (420 Wa). After installing the compact spare on your
vehicle, you should stop as soon as possible and make sure your spare tire
is correctly inflated. The compact spare is made to perform well at posted
speed limits for distances up to
3,000 miles (5 000 km). The compact
spare is made to go up to
3,000 miles (5 000 km), so you can finish your
trip and have your full-size tire repaired or replaced where you want. Of
course, it’s best to replace your spare with a full-size tire as soon as you
can. Your spare will last longer and be
in good shape in case you need it
again.
Your anti-lock brake system warning light may come on when you are
driving with a compact spare. See “Anti-Lock Brake System Warning
Light”
in the Index.
NOTICE:
Don’t take your compact spare through an automatic car wash \
with guide rails. The compact spare can get caught on the rails.
That can damage the tire and wheel, and maybe other parts
of
your vehicle.
Don’t use your compact spare on some other vehicle.
And don’t
mix your compact spare or wheel with other wheels or tires.
They won’t fit. Keep your spare and its wheel together.

proper Cadillac Service Manual. It tells
you much more about how to
service your Cadillac than this manual can.

manual, see “Service Publications” in the Index.

If you plan on 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).

FUEL ECOlVOhfY
Your fuel economy (miles per gallon or liters per 100 kilometers) can vary
depending on how your Cadillac is driven. Several vehicles like yours
have been driven through a standard test and their actual fuel economy
was recorded. These readings were adjusted and printed on the fuel
economy window sticker which was attached to your
new Cadillac when it
was delivered and in the Gas Mileage Guide which is available from your
dealership.
c
The fuel economy estimates are based on results of tests required by the
U. S. Environmental Protection Agency (EPA). These tests are used to
certify that vehicles meet the Federal emissions and fuel economy
standards. Cadillac tests prototypes of new vehicles and submits the results
to the EPA. The EPA then confirms the accuracy
of the figures provided by
Cadillac. The vehicles are driven by a professional driver under controlled
-
laboratory conditions, on an instrument similar to a treadmill. These
procedures ensure that each vehicle is tested under identical conditions.
There are
two different fuel economy estimates for each vehicle, one for
city driving and one for highway driving.
To develop these two estimates,
separate tests are used to represent typical everyday city and rural driving.

ENGINE OIL
A “CHECK OIL LEVEL? message will appear when the engine oil is
approximately a quart low.
If the message is displayed, check the dipstick
level and add oil as needed.
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.
L
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.

in all the way. Remove it again, keeping the tip lower, and check
the level.
when to Add Oil
If the oil is at or below the ADD line, ADD mark, 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.

Downloaded from www.Manualslib.com manuals search engine 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 Cadillac has an “Oil Life Indicator.” This feature will let you know
when to change your oil
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change. Under severe
conditions, the indicator may come on before
3,000 miles (5 000 km).
Never drive your vehicle more than 7,500 miles (12 000 km) or 12 months
without an oil change.
The system won’t detect dust in the oil.
So, if you drive in a dusty area, be
sure to change your oil every
3,000 miles (5 000 km) or sooner if the
“Change Oil Soon” light comes on. Remember to reset the Oil Life
Indicator when the oil has been changed. For more information, see “Oil
Life Indicator” in the Index.
How to Reset the Oil Life Indicator
After the oil has been changed, display the “OIL LIFE LEFT” message
by pressing the INFORMATION button. Then press and hold the
RESET button until the display shows “100”. This resets the
oil life index.
The message will remain off until the next oil change
is needed. The
percentage
of oil life remaining may be checked at, any time by pressing
the INFORMATION button several times until the “OIL LIFE LEFT”
message appears. For more information on the Oil Life Index feature,
see
“Oil Life Index” in the Index.
Engine Coolant Heater (Engine Block Heater)
An engine coolant heater can be a big help if you have to park outside in
very cold weather, 0” F (-18OC) or colder. If your vehicle has this option,
see “Engine Coolant Heater” in the Index.
