2000 CADILLAC ELDORADO engine oil

2-72
CHECK OIL LEVEL - 36: For correct operation of the
low oil sensing system, your vehicle should be on a level
surface. A false CHECK OIL LEVEL message may
appear if the vehicle is parked on grades. The oil level
sensing system does not check for actual oil level if the
engine has been off for a short period of time, and the oil
level is never sensed while the engine is running. If the
CHECK OIL LEVEL message appears and your vehicle
has been parked on level ground with the engine off for
at least 30 minutes, the oil level should be checked by
observing the oil dipstick. Prior to checking the oil level,
be sure the engine has been off for five minutes and your
vehicle is on a level surface. Then check the dipstick and
add oil if necessary. See ªEngine Oilº in the Index.
CHECK WASHER FLUID
- 25: This message will
appear for several seconds indicating that you need
windshield washer solvent.
CRUISE ENGAGED
- 43: This message will appear
for a few seconds when you select a speed at which
to cruise.
DOOR AJAR
- 141: A door other than the driver's
is open or ajar when this message appears. The vehicle's
engine must be running and the transaxle not in
PARK (P) for this message to display. A chime will
also sound when the vehicle's speed is greater than
5 mph (8 km/h).DRIVER DOOR AJAR
- 140: This message
will display when the vehicle is being shifted out of
PARK (P) with the engine running to signal that the
driver's door is open or ajar. A chime will also sound
when the vehicle's speed is greater than 5 mph (8 km/h).
ENGINE COOLANT HOT, IDLE ENGINE
- 44:
This message will appear when the engine coolant
temperature is over 248
F (126
C). To avoid added
strain on a hot engine, turn off the climate control
system. Stop and allow your vehicle to idle until it cools
down or the message is removed. If it does not cool
down, turn off the engine and have it serviced before
driving it again. Severe engine damage can result from
an overheated engine. See ªEngine Overheatingº in
the Index.
ENGINE HOT
- A/C OFF - 16: This message displays
when the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off so that air conditioned air is not delivered.
If the coolant temperature returns to normal, you must
select AC to return to a normal A/C compressor
operation. If this message continues to appear,
have the system repaired as soon as possible to avoid
compressor damage.

enough outside and the Twilight Sentinel control is off,
a HEADLAMPS SUGGESTED message will display on
the DIC. This message informs the driver that turning on
the exterior lamps is recommended even though the
Daytime Running Lamps (DRL) are still illuminated
(it's become dark enough outside to require the
headlamps and/or other exterior lamps).ICE POSSIBLE
- 13: This message appears when
the outside air temperature is cold enough to create icy
road conditions.

2-82 Oil Life Indicator
This feature lets you know when to change the engine
oil. It's based on the engine oil temperatures and your
driving patterns. To see the display, press the SKIP
INFO button several times until XX OIL LIFE LEFT
appears. If you see 99% OIL LIFE LEFT, 99 percent
of your current oil life remains.
The Driver Information Center (DIC) may display a
CHANGE ENGINE OIL message. Always keep a
written record of the mileage and date when you
changed your oil. For more information, see the
Maintenance Schedule booklet. If you see CHANGE
ENGINE OIL, it means that you have no oil life left
and you should change your engine oil right away.
When the oil is changed, you'll need to reset the system.
See ªOil Life Indicator, How to Resetº in the Index.

4-22
Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh
-- such as after a day's
work
-- don't plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll find experienced and able service experts in
Cadillac dealerships all across North America. They'll
be ready and willing to help if you need it.
Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full?
Are all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble
-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?

4-38 Maintenance When Trailer Towing
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule booklet
for more on this. Things that are especially important in
trailer operation are automatic transaxle fluid (don't
overfill), engine oil, drive belt, cooling system and brake
system. If you're trailering, it's a good idea to review
this information before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See ªEngine Overheatingº
in the Index.

5-10 Overheated Engine Protection
Operating Mode
Should an overheated engine condition exist and the
message ENGINE OVERHEATED, STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups of cylinders helps prevent engine damage.
In this mode, you will notice a loss in power and engine
performance. This operating mode allows your vehicle
to be driven to a safe place in an emergency; you may
drive up to 50 miles (80 km). Towing a trailer in the
overheat protection mode should be avoided.
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life indicator. See ªEngine Oilº in
the Index.
If Steam Is Coming From Your Engine
CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away from
the engine if you see or hear steam coming from it.
Just turn it off and get everyone away from the
vehicle until it cools down. Wait until there is no sign
of steam or coolant before you open the hood.
CAUTION: (Continued)

5-13
CAUTION:
An electric engine cooling 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 surge tank is boiling,
don't do anything else until it cools down.
A low coolant level should be indicated by a CHECK
COOLANT LEVEL message on the Driver Information
Center. If it is, you may have a leak in the radiator
hoses, heater hoses, radiator, water pump or somewhere
else in the cooling system.
CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them.
If you do, you can be burned.
Don't run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.
See ªOverheated Engine Protection Operating
Modeº in the Index.

5-15
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 mixture will. Your vehicle's coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
CAUTION: (Continued)
CAUTION: (Continued)
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 mixture of clean, drinkable water
and DEX
-COOL
coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So use the recommended coolant.
CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
