1994 CADILLAC SEVILLE oil pressure

Downloaded from www.Manualslib.com manuals search engine Engine Oil Light (Canadian \Export On&)
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 “Run” or “Start.”
It goes off
once you start your engine. That’s just a check to be sure the light works.
If it doesn’t, 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 oil isn’t going through
your engine properly. You could be low on oil, or you might have some
other oil problem.
NOTICE:
Damage to your engine from neglected oil problems can be
costly and
is not covered by your warranty.

HIGmAY HITNOSIS
Is thh Actually such a condition as “highway hypnosis”? Or is it just
plain falling asleep at the wheel? Call it highway hypnosis, lack
of
awareness, or whatever.
There is something about an easy stretch
of road with the same scenery,
along with the hum
of the tires on the road, the drone of the engine, and
the rush
of the wind against the vehicle that can make you sleepy. Don’t
let it happen to you!
If it does, your vehicle can leave the road in less than
a second, and you could crash and be injured.
What can you do about highway hypnosis? First, be aware that it can
happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with a comfortably cool
interior.
Keep your eyes moving. Scan the road ahead and to the sides. Check
your rearview mirrors and your instruments frequently.
If you get sleepy, pull off the road into a rest, service, or parking area
and take a nap, get some exercise, or both. For safety, treat drowsiness
on the highway as an emergency.

Don’t rub it roughly.
0 As soon as you’ve cleaned the section, use a sponge to remove the
suds.
0 Rinse the section with a clean, wet sponge.
Wipe off what’s left with a slightly damp paper towel or cloth.
0 Then dry it immediately with a blow dryer or a heat lamp.
NOTICE: I-
Be careful with a hair dryer or heat lamp. You could scorch the

0 Wipe with a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean off better with just water and mild soap.
If you need to use a solvent:
Gently scrape excess soil from the trim material with a clean, dull
knife or scraper. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the outside of the
stain, “feathering” toward the center. Keep changing
to a clean
section
of the cloth.
0 When you clean a stain from fabric, immediately dry the area with an
air hose, hair dryer, or heat lamp
to help prevent a cleaning ring. (See
the previous
NOTICE.)

Downloaded from www.Manualslib.com manuals search engine The Northstar engine is designed to minimize the need for routine
maintenance while incorporating systems to remind the driver when
service is required.
An oil life index indicator monitors ongoing operating
conditions and reminds the driver when an oil change is needed.
A low
coolant warning message keeps track of the level of this vital fluid. Direct
acting hydraulic tappets provide maintenance free zero lash operation of
the
32 valves from idle to the 6500 rpm redline. The camshafts are driven
by a
two stage roller chain assembly which is designed to provide quiet
maintenance free operation. Platinum tipped spark plugs increase the
replacement interval to
100,OO miles.
The four valves per cylinder design provides more efficient engine
breathing, resulting in higher power than comparable
two valve engines.
The induction system uses smooth thermoplastic tubes
to channel air into
the cylinders. These smooth tubes simulate the elaborate port polishing
methods used on racing engines. The shape and length
of the tubes
boosts horsepower by using sonic pressure waves created by the motion of
the inlet valves to increase the amount
of air entering each cylinder. Once
the intake charge has entered the cylinder, the centrally located spark
plug ensures fast and efficient burning of the fuel/air mixture.
This engine is designed to be very durable. The aluminum block has
cast-in-place iron cylinder liners for greater wear resistance. High
strength connecting rods support the
free floating piston pins in bronze
bushings for superior high speed performance.
The fillets of the nodular
iron crankshaft undergo a high pressure compression rolling operation to
improve their resistance to fatigue.
Quiet operation is enhanced by the use
of special materials and designs.
The front cover of the engine is stamped from laminated steel which
damps out noise. Special cam cover gasket seals isolate va1v.e train
operation. The fuel injectors are placed inside the induction system
housing to eliminate the clicking noise which
is common to other fuel
injected engines.
The Northstar engine is designed to provide years
of efficient, reliable,
satisfying operation.

The Hydra-Matic 4T80E transaxle has been designed to complement the
output characteristics of the Northstar engine. The innovative design
incorporates several features which enhance its overall operation.
This transaxle is the first
of a new generation of “SMART” transmissions.
The computer which controls the electronic shift solenoids adapts to
changing environments while you drive. This provides consistent high
quality shifts under all conditions. Communication between the engine
and transaxle through this computer controls engine output during
activation
of torque management or traction control. Smooth shifting is
ensured by design. Hydraulic accumulators control shift pressures and all
shifts are made to free wheeling elements.
The 4T80E uses a
dry sump lubrication system with a scavenger pump.
This unique feature er,ables the transaxle to maintain adequate
pressurized oil supply during all maneuvers.
