Downloaded from www.Manualslib.com manuals search engine BATTERY VOLTS HIGH
This message shows that the electrical charging system is overcharging,
(more than 16 volts). To avoid being stranded have the electrical system
checked by your Cadillac dealership at your earliest convenience. You can
reduce the charging overload
by using the accessories. Turn on the lights,
radio, set the Climate Control on
“AUTO” and the fan speed on “HI”
and turn the rear window defogger on. You can monitor battery voltage
on the Driver Information Center by toggling the “INFORMATION”
button. When the engine is running, the normal range
is 11.5 to 15.5
volts.

BATTERY VOLTS LOW
This message will appear when the electrical system is charging less than
10 volts, or if the battery has been drained. If this message appears
immediately after starting it is possible that the generator can still
recharge the battery. The battery should recharge after driving a few
miles and the message should go out. If this message appears while
driving or after starting your vehicle and stays on, have it checked
immediately to determine the cause
of this problem. To help the
generator recharge the battery quickly,
you can reduce the load on the
electrical system by turning
off your accessories. You can monitor battery
voltage on the Driver Information Center by toggling the
“INFORMATION’’ button. The normal range is
11.5 to 15.5 volts.
CHANGE TRANS FLUID (Northstar Only)
This message will appear when it is time to replace the transaxle fluid.
See your maintenance booklet
for the proper fluid and change intervals.
CHECK BRAKE FLUID
This message is displayed to inform the driver that the brake reservoir
fluid level is low. Check the brake reservoir level and add as needed.
Have the brake system serviced by a Cadillac technician as soon as
possible.
If the brake warning light is on, follow the directions in that
section.
CHECK COOLANT LEVEL (Northstar Only)
This message will appear when there is a low level of engine coolant.
Have the cooling system serviced by a Cadillac technician as soon as
possible.

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,OO 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 forged steel connecting rods support the free floating
piston pins
in bronze bushings for superior high speed performance. The
fillits
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. We
think it is also just plain fun to drive.
