This message will appear when your engine oil is approximately a quart
low. If this message is displayed, check the
oil and add as needed.
CHECK WASHER FLUID - 25
This message will appear for a few seconds indicating that you need
washer solvent.
CHANGE OIL SOON - 40
This message will appear when your engine oil is less than 10 percent or
the mileage since the last
oil change is more than 6750 miles.
CHANGE ENGINE OIL - 82
This means that the life of your engine oil has expired and it should be
changed immediately. See engine
oil and filter recommendations in the
Maintenance Schedule. After an
oil change, the Oil Life Index must be
reset. See “Oil Life Indicator” in the index
on how to reset it.
CRUISE ENGAGED - 43
This message will appear for a few seconds when you select a speed to
cruise at.
ENGINE COOLANT HOT - 44
This message will appear when your engine coolant temperature is over
126°C (259OF). To avoid added strain on a hot engine, turn off your
Climate Control system, and stop and allow your vehicle to idle until it
cools down or the message
is removed. If it does not cool down, turn off
your engine and have it serviced before driving it again. Severe engine
damage can result from an overheated engine. See “Engine Overheating”
in the Index.
ENGINE HOT - A/C COMPRESSOR OFF - 16
This message will appear when the Climate Control is in “Auto” or
“Defrost” and the engine coolant is hotter than the normal operating
temperature.
To avoid added strain on a hot engine the air conditioning
compressor is automatically turned
off. When that happens, air
conditioned air is not delivered.
If the coolant temperature returns to
normal, the
A/C operation returns to normal.

receives an incorrect feedback from the system, an error code
will be set
in memory and a “SERVICE RIDE CONTROC’ message will display on
the Driver Information Center. If this message should appear, have your
vehicle serviced at your Cadillac dealer at your earliest convenience.
Oil Life Indicator
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
“XXX
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]).

4. Stop and have someone pick up and store the chocks.
Engine Cooling When Trailering
Your cooling system may temporarily overheat during severe operating
conditions such as;
Climbing grades steeper than 4% at ambient temperatures above
90” Fahrenheit (32’Celsius) with a loaded vehicle and trailer.
Stopping after high-speed driving.
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” 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 transmission
selector to
P (Park) and allow the engine to idle. Do not turn off 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 to
resume. At that
time resume driving at a reduced speed. Return to
normal driving after
10 minutes if the “ENGINE COOLANT HOT”
message
is not displayed.
Maintenance when Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer.
See
the Maintenance Schedule for more on this. Things that are
especially important
in trailer operation are automatic transaxle fluid
(don’t overfill), engine oil, belts, cooling system, and brake wear. Each of
these is covered
in this manual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea to review these sections
before
you start your trip.
Check periodically
to see that all hitch nuts and bolts are tight.

DO NOT USE SAE 1OW-40, SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
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 OF (16 C)
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 2OW-50.

ENGINE COOLANT 7
The following explains your cooling system and how to add coolant when (. I
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 (-37OC) .
0 Give boiling protection up to 262 F (128 C) .
0 Prote-ct against rust and corrosion.
Help keep the proper engine temperature.
Let the warning-lights work as they shoula.
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.
