computer receives an incorrect feedback from the system, an error code will
be set in memory and a “SERVICE RIDE CONTROE’ message will display
on the Driver Information Center. If

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
now 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]).

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.
