EXTERIOR LAIMP HOUSINGS
NOTICE:
Your Cadillac’s lamp housings are designed with small vents so
moisture will be removed when the lights are on, or after driving
for a short time.
If an excessive amount of moisture is present
which does not clear, see your Cadillac dealership for service.\

The tire has a puncture, cut, or other damage that can’t be repaired
well because
of the size or location of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at the Tire-Loading
Information label.
The tires installed on your vehicle when it was new had a Tire
Performance Criteria Specification (TPC Spec) number on each tire’s
sidewall. When you get new tires, get ones with that same
TPC Spec
number. That way, your vehicle
will continue to have tires that are
designed to give proper endurance, handling, speed rating, traction, ride
and other things during normal service
on your vehicle. If your tireshave
an all-season tread design, the TPC number will be followed by a
“MS”
(for mud and snow).
If you ever replace your tires with those not having a TPC Spec number,
make sure they are the same size, load range, speed rating and
construction type (bias, bias-belted or radial) as your original tires.
Uniform Tire Quality Grading

States National Highway Traffic Safety Administration which grades tires

to vehicles sold in the United (States.)
Treadweat
. . , .--, . .
r The treadwear grade is .a comparative rating based on the wear rate of
the tire when tested .under controlled -conditions on a specified
.government test course. .For example, a tire graded 150 would \
wear one
and a half
(I 1/2) times as well on the government course-as a tire graded
’ 100. The relative performance of tires depends uponthe .actual
conditions of.their use, however, and may depart significant@
frorri the
norm due to variationsin driving habits, service practices and differences
in rodd characteristics and climate.
.r Daction -A, B, C
t The traction grades, from highest to lowest are: A, B, and C. They
represent the tire’s ability to stop on wet-pavement as measured under
controlled conditionson specified government test surfaces of asphalt
’ and concrete. A tire marked C may have poor traction p.erformance.
Warning: The traction. grade assigned to this tire is based on braking
(straight-ahead) traction tests and doemot include cornering (turning)
r traction.
r Temperature -A, B, C
I I
The temperature grades. are A (the. highest), B, and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions.on a specified indoor laborato\

test .wheel. Sustained
high tevperature can cause the material of the tire
to degenerate and reduce tire.life, and excessive temperature can lead to
- sudden tire failure. The.gradq C corresponds to a level of performance
1- which all passenger car tires mustmeet under the,Federal Motor Vehicle
Safety Standard
No. 109. Grades €3 and A represent higher levels of
performance on thelaboratory test wheel than the.minimum required\

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

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.

front corner
of the instrument panel, on the driver’s side. You can see it if
you look through the windshield from outside your vehicle. The VIN also
appears
on the Vehicle Certification and Service Parts labels and the
certificates
of title and registration.
Engine Identificatiun
The eighth character in your VIN is the engine code. This code will help
you identify your engine, specifications, and replacement parts.
SERWCE PARTS IDENTIFICATION LABEL
You’ll find this label
on the spare tire cover. It’s very helpful if you ever need to order parts.
On this .label is:
-a your VIN,
the model designation,
paint information, and
a list of all production options and special equipment.
Be sure that this label is not removed from the vehicle.

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.

Your vehicle uses an independent shortflong arm rear suspension. All the
rear suspension components
are mounted on a suspension support which
is attached
to the body at four points and is fully isolated with bushings
and insulators to minimize road noise. Each rear wheel
is connected to
the suspension support through the suspension knuckle using an upper
and lower control arm and toe link.
The control arms and toe link are attached to the suspension support on
the inboard side, and to a suspension knuckle on the outboard side. The
hub and bearing assembly is mounted to the knuckle and is a single,
non-serviceable unit which eliminates the need for wheel bearing
adjustment. The load leveling (ELC) shock absorbers are attached to the
lower control arm, with the upper end
of the shock attached to the
suspension support. The springs are held in position between the lower
control
arms and a pocket in the suspension support.
