If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work
well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can
corrode, and your engine oil can deteriorate quickly. Your vehicle’s
oxygen sensor will be damaged. All of that means costly repairs that
wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write us at the following address for advice. Just tell us
where you’re going and give your Vehicle Identification Numbe\
r (VIN).

FUEL ECONOMY
Your fuel economy (miles per gallon or liters per 100 kilometers) can vary
depending on how your Cadillac is driven. Several vehicles like yours
have been driven through a standard test and their actual fuel econ\
omy
was recorded. These readings were adjusted and printed on the fuel
economy window sticker which was attached
to your new Cadillac when it
was delivered and in the Gas Mileage Guide which is available from your
dealership.
The fuel economy estimates are based on results of tests required by the
U. S. Environmental Protection Agency (EPA). These tests are used to
certify that vehicles meet the Federal emissions and fuel economy
standards. Cadillac tests prototypes of new vehicles and submits the
results to the EPA. The EPA then confirms the accuracy of
the figures
provided by Cadillac. The vehicles are driven by a professional driver
under controlled laboratory conditions, on an instrument similar \
to
a
treadmill. These procedures ensure that each vehicle is tested under
identical conditions.

NOTICE:
Continuing to drive with worn-out.brake pads could result in
costly brake repair.
Some driving conditions or climates may cause a brake squeal when the
brakes are first applied or lightly applied. This does not mean something
is wrong with your brakes.
Brake linings should always be replaced as complete axle sets. \
Brake Pedal Travel
See your dealer if the brake pedal does not return to normal height, or if
trouble.
F I L there is a rapid increase in pedal travel. This could be a sign of brake
r
Brake Adjustment
Every time you make a moderate brake stop, your disc brakes adjust for
wear.
If you rarely make a moderate or heavier stop, then your brakes
might not adjust correctly.
If you drive in that way, then -- very carefully --
make a few moderate brake stops about every 1000 miles (1600 km), so
your brakes will adjust properly.

buildup and possible tire failure.
These grades are molded on
the sidewalls of passenger car tires.
While the tires available as standard or optional equipment on General
Motors vehicles may vary with respect to these grades, all such tires meet
General Motors performance standards and have been approved for use
on General Motors vehicles. All passenger type
(P Metric) tires must
conform to Federal safety requirements
in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tire life and best overall performance.
In most cases, you
will not need to have your wheels aligned again.
However,
if you notice unusual tire wear or your vehicle pulling one way
or the other, the alignment may need to be reset. If you notice your
vehicle vibrating when driving
on a smooth road, your wheels may need
to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly corroded. If wheel nuts
keep coming loose, the wheel, wheel bolts, and wheel nuts should be
replaced. If the wheel leaks air, replace it (except some aluminum wheels,
__
which can sometimes be repaired). See your Cadillac dealer if any of
these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load carrying capacity, diameter,
width, offset, and be mounted the same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts, or wheel nuts,
replace them
only with new GM original equipment parts. This way, you
will be sure to have the right wheel, wheel bolts, and
wheel nuts for your
Cadillac model.

repaired right away. Bare metal will corrode quickly and may develop

It Minor chips and scratches can be repaired with touch-up materials
available from your dealer or other service outlets. Larger areas of finish

UNDERBODYlMAlNTEANCE
Chemicals used for ice and snow removal and dust control can collect on
the underbody.
If these are not removed, accelerated corrosion (rust) can
occur on the underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion protection.
At least every spring, flush these materials from the underbody with plain
water. Clean any areas where mud and other debris can collect. Dirt
packed in closed areas
of the frame should be loosened before being
flushed. Your dealer or an underbody vehicle washing system can do this
for you.
CHEMICAL PMNT SPOTTING
Some weather and atmospheric conditions can create a chemical fallout.
Airborne pollutants can fall upon and attack painted surfaces on your
vehicle. This damage can take
two forms: .blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into the paint
surface.
Although no defect in the paint job causes this, Cadillac will repair, at no
charge to the owner, the surfaces
of new vehicles damaged by this fallout
condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever comes first.

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.
