This feature lets you know when to change your engine oil. It’s based
upon the engine oil temperatures and your driving patterns.
To see the display,
press the Information
button several times
until “XX OIL LIFE
LEFT” appears.
You’ll see how much oil life you have left, as a percentage.
So, if you see
“95 OIL LIFE LEFT,” for example, that means that the way you’re
driving your car, 95% of your current oil life is still left.
The Oil Life Indicator may say to change the oil sooner than your
maintenance schedule. This can happen
if driving conditions, such as
short trips in cold weather, cause shorter oil life. Always keep a written
record
of the mileage and date when you last changed your oil. For more
information on when to change your oil, see the Cadillac Maintenance
Schedule Booklet.
If you see “CHANGE OIL SOON,” it means that you have less than 10%
of your oil life left, and you should consider changing your engine oil.
If you
see “CHANGE ENGINE OIL,” it means the oil life is gone and
you should change the oil right away (certainly within 200 more miles
[ 320 km]) .
The system probably will say to change the oil between 3000 miles (5000
km) and 7500 miles (12500 km), but it may even say to change it before
3000 under
very severe conditions. It all depends on your driving patterns.
If it’s been 7500 miles (12500 km) it always says to change the oil.

Your cooling system may temporarily overheat during severe operating
conditions such as;
Climbing grades steeper than 4% at ambient temperatures above
90 Fahrenheit (32O Celsius) with a loaded vehicle and trailer.
I_ Stopping after high-speed driving.
0 Idling for long periods in stop and go traffic.
If “ENGINE HOT A/C COMPRESSOR
OFF” message appears on the
Driver Information Center, do not be alarmed. This is a normal function
designed to reduce the load
on the engine and cooling system. You can
continue to drive your vehicle.
If “ENGINE COOLANT HOT IDLE ENGINE’’ message appears on
the Driver Information Center, pull off to the side of the road as soon as
it is safe to do
so. When the vehicle is at a complete stop, shift the
the engine or increase engine speed above a normal idle. Within
two or
three minutes the system should cool sufficiently to allow A/C operation
normal driving after
10 minutes if the “ENGINE COOLANT HOT
IDLE ENGINE” message is not displayed.

IF NEITHER SAE 5W-30 NOR SAE 1OW-30
GRADE OILS ARE AVAILABLE, SAE 30 GRADE MAY BE USED AT TEMPERATURES
ABOVE 40 DEGREES F (4 OEGREES C).
ANY OTHER GRADE OIL NOT RECOMMENDED DO NOT USE SAE 1OW-40, SAE 2OW-50 OR
As shown in the 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 (16OC)
before your next oil change. When it's
very cold, 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.

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 -34OF (-37 C).
0 Give boiling protection up to 262OF (128OC).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
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 this mixture, you don’t need to add anything else.
