If you let your tires spin at high speed, they can explode and you
or others could be injured. And, the transaxle or other parts
of
the vehicle can overheat. That could cause an engine fire or
other damage. When you’re stuck, spin the wheels as little as
possible. Don’t spin the wheels above
35 mph (55 km/h) as
shown on the beedometer.

Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That
will clear the area
around your front wheels. Then shift back and forth between
“R’
(Reverse) and a forward gear, spinning the wheels as little as possible.
Release the accelerator pedal while
you shift, and press lightly on the
accelerator pedal when the transaxle is
in gear. If that doesn’t get you out
after
a few tries, you may need to be towed out. If you do need to be
towed out, see “Towing Your Vehicle”
in the Index.

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.

oil (in Canada, GM Engine Oil) meets all the
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.

Downloaded from www.Manualslib.com manuals search engine How To Reset the Oil Life Indicator: After the oil has been changed,
press and hold the
“RANGE” and “RESET” buttons between 5 and 60
seconds. Once the buttons are released the “CHANGE OIL SOON”
light will flash 4 times to indicate it has reset to 100. If the “CHANGE
OIL SOON” light comes on for 5 seconds it did not reset. You will need
to reset the system again. The percentage
of oil life remaining may be
checked at any time by pressing the
“RANGE” and “FUEL USED” on
the Fuel Data center.
Engine Block Heater: An engine block heater can be a big help if you
have to park outside
in very cold weather, O°F (-18OC) or colder. If your
vehicle has this option, see “Engine Block Heater” in the Index.
What to Do with Used Oil:
’
A CAUTION:
Used engine oil contains things that have caused skin cancer in
laboratory animals. 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 engine oil.
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 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.

Downloaded from www.Manualslib.com manuals search engine 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:
0 Give freezing protection down to -34°F (-37°C) .
0 Give boiling protection up to 262°F (128” C) .
0 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 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 these, you don’t need to add anything else.
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
Waf--- and
a proper anti” e. .-

leaking out
of the brake system. If it is, you should have your brake
system fixed, since a leak means that sooner
or later your brakes won’t
work well, or won’t work at all.
So, it isn’t a good idea to “top off” your
brake fluid. Adding brake fluid won’t correct a leak.
If you add fluid when
your linings are worn, then you’ll have too much fluid when you get new
brake linings.
You should add (or remove) brake fluid, as necessary, only
when work is done on the brake hydraulic system.

When your brake fluid falls to a low level, your brake warning light will

To Check Brake Fluid:
You can check the brake fluid without taking off the cap. If it’s low, fill it
to the maximum “FLUID LEVEC’ indicator.
