Downloaded from www.Manualslib.com manuals search engine STOP ENGINE ENGINE 0-TED - 42
This message will appear when your engine has overheated. Stop and
turn your engine off immediately to avoid severe engine damage. See
“Engine Overheating”
in the Index.
SERVICE VEHICLE SOON - 03
This message will appear if there is a problem with your Emission
Control System. If the “SERVICE ENGINE SOON” light on the
instrument panel and this message appears and then turns
off, it is an
indication that a temporary problem has cleared itself. Have your vehicle
checked at your earliest convenience.
STOP ENGINE LOW OIL PRESSURE - 35
If this message appears while the engine is running, stop the engine and
do not operate it until the cause of low oil pressure is corrected. Severe
damage to the engine can result.
SERVICE AIR BAG SYSTEM - 83
If this message appears, there is a problem with your Supplemental
Inflatable Restraint (Air Bag) system. Let only a qualified technician
work
on your vehicle. See your Cadillac dealer for service at once.
THEFT SYSTEM PROBLEM/CAR MAY NOT RESTART - 34
This message means there is a problem in the Personalized Automotive
Security System (PASS Key@ 11). PASS Key@ I1
will prevent the vehicle
from restarting
if it is turned off, so you should take the vehicle to a
proper service center before turning the engine
off. Never leave an
unattended vehicle with the engine running. Once you are where you can
get service, turn the engine off and then try to restart it. If
the vehicle
does not restart, the PASS Key@ I1 system will need servicing.
TRACTION ACTIVE - 91
If your vehicle is equipped with Traction Control, this message will be
displayed if Traction Control is being used to reduce wheel slippage.
TRACTION DISABLED - 88
If your vehicle is equipped with Traction Control, this message will be
displayed
if a problem is noted in the Traction Control System. Have your
vehicle serviced as soon as possible.

r If you need to use a solvent:
r
rn Gently scrape excess soil from the trim material with a clean, dull

(preferably cheesecloth).Cleaning should start at the outside
of the

oils, wax crayon, tar and
asphalt.
Carefully scrape off excess stain.

Downloaded from www.Manualslib.com manuals search engine The Northstar engine is designed to require less maintenance than many
other DOHC
V-8 engines. Engine systems are designed 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 100,000 miles.
The four valve per cylinder design provides more efficient engine
breathing which results in higher power than comparable
two valve
engines. The central location
of each spark plug ensures a fast and
complete burning of the fuel/air mixture. The induction system uses
smooth thermoplastic tubes to channel air into the cylinders. The
smoothness
of the tubes is equivalent to the elaborate port polishing
methods used for race car engines. Careful design using 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.
The Northstar engine is also 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 valve 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.

4T80-E Transaxle
r
The 4T80-E 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 enables the transaxle to maintain adequate
pressurized oil supply during all maneuvers.
