low oil pressure CADILLAC DEVILLE 2001 8.G Owners Manual

Oil Pressure Light
This light tells you if there
could be a problem with
your engine oil pressure.
The light goes on when you turn your key to ON. It goes
off once you start your engine. That's a check to be sure
the light works. If it doesn't come on, be sure to have
it fixed so it will be there to warn you if something
goes wrong.
When the light comes on and stays on, it means that
oil isn't flowing through your engine properly. You
could be low on oil and you might have some other
system problem.CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches fire. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

LF-RF-LR-RR TIRE (If Equipped): On vehicles
equipped with the Tire Pressure Monitor, this message
shows the tire pressure for each tire (left front, right
front, left rear and right rear). Pressing the INFO button
will scroll through the tire pressure for each of the
four tires, such as:

34 PSI LF TIRE OK or

234 kPa LF TIRE OK
If a tire pressure is below 24 PSI (165 kPa) or above
36 PSI (248 kPa), the message will appear as shown
above except it will show TIRE LOW or TIRE HIGH
as appropriate. If desired, the tire pressure information
can be programmed not to appear when using the
INFO button to scroll through the DIC displays.
See ªVehicle Programming and Personalization
Featuresº in the Index.
If a low or high tire pressure is detected by the system
while driving, a CHECK TIRE PRESSURE message
will appear in the display. If this occurs, press the
INFO button to scroll to the tire(s) with a low or high
pressure condition. See ªDriver Information Center
(DIC) Messagesº in the Index for more information.ENGINE OIL LIFE (Reset): Press the INFO button
to display ENGINE OIL LIFE, then press and hold the
INFO RESET button until 100% ENGINE OIL LIFE is
displayed. (This only needs to be reset after you have
had the oil changed.)
TRANSMISSION FLUID LIFE MONITOR: Under
normal conditions, the rate of deterioration of the
transmission fluid is slow. See the Maintenance
Schedule booklet for proper fluid and change intervals.
Press the INFO button to display TRANS FLUID LIFE,
then press and hold the INFO RESET button until
100% TRANS FLUID LIFE is displayed. (This only
needs to be reset after you have had the fluid changed.)
ENG/MET: Press this button to display information in
the English (miles) or metric (kilometers) system.

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 a grade. 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 checked 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 a few 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 TIRE PRESSURE
- 144: This message is
displayed when the Tire Pressure Monitor (TPM) system
detects a low or high tire pressure condition in one or
more of the road tires. By pressing the INFO button
up or down the DIC display will show which tire or tires
do not have the correct inflation pressure. A ªLOW TIREº condition exists when the tire's air
pressure is under 24 psi (165 kPa) and a ªHIGH TIREº
condition exists when the tire's air pressure is above
36 psi (248 kPa).
The system will display the air pressure, the tire location
(LF, RF, RR or LR) and if the air pressure is low or
high. The tire pressure information is available in
English or metric measurements. For example, a driver's
side front tire that is low may be shown as: 22 PSI LF
TIRE LOW.
The correct tire inflation pressure should be set to those
shown on the Tire Loading
-Information Label, located on
the rear edge of the driver's door. For more information
regarding proper tire inflation, see ªInflation
-- Tire
Pressureº in the Index. If a tire is low, you should stop
as soon as possible and inspect your tire(s) for damage.
If a tire is flat, see ªIf a Tire is Flatº in the Index.

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?
