This rich tradition continues
into the
'90s as Cadillac became the
first automobile manufacturer
to be
awarded the prestigious Malcolm
Baldrige National Quality Award.
The
1992 Seville STS was the
first car ever to win
all three major
automotive awards: Car of the Year,
Motor Trend; Ten Best List, Car
&
Driver; Car of the Year, Automobile
Magazine.

A 1993 Cadillac Allantit in stock
technical configuration, was selected
as the pace car for the 76th Indianap-
olis
500. The demanding pace car
performance and handling require- ments were met because of such
advances as the Northstar system.
The system includes the
32 valve,
dual overhead camshaft, Northstar
4.6 liter V8 engine, 4T80 E electroni-
cally controlled automatic transaxle,
road sensing suspension,. speed sen-
sitive steering, antilock brakes and
traction control. For more than nine decades
Cadillac has been
a leader in quality
and technical innovation. Now more
than ever, substance takes shape

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’II). PASS-Key’II
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’II system
will need servicing.
TRACTION ACTIVE - 46
If your vehicle is equipped with Traction Control, this message will be
displayed
if Traction Control is being used to reduce wheel slippage.

controls braking pressure accordingly.
Remember: Anti-lock doesn’t change the time you need to get your foot
up to the brake pedal. If you get too close to the vehicle in front
of you,
you won’t have time to apply your brakes
if that vehicle suddenly slows or
stops. Always leave enough room up ahead to stop, even though you have
anti-lock brakes.
To Use Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down and let anti-lock
work for you. You may hear the anti-lock pump or motor operate, and
feel the brake pedal pulsate, but this is normal.
Traction Control System (Option)
Your vehicle may have a traction control system that limits wheel spin.
This is especially useful
in slippery road conditions. The system operates
only
if it senses that one or both of the front wheels are spinning or
beginning to lose traction. When this happens, the system works the front
brakes and reduces engine power (by shutting
off fuel injectors) to limit
wheel spin.
The “TRACTION ACTIVE” message will display on the Driver
Information Center when
the traction control system is limiting wheel
spin. See “Driver Information Center Messages” in the Index.
You may
feel the system working, or you may notice some noise, but this is normal.
If your vehicle is in cruise control when the traction control system begins
to limit wheel spin, the cruise control will automatically disengage. When
road conditions allow you
to safely use it again, you may re-engage the
cruise control. (See “Cruise Control”
in the Index.)
The “TRACTION DISABLED” message will display on the Driver
Information Center if there’s a problem with your traction control system.
See “Driver Information Center Messages” in the Index. When this
message is displayed, the system will not limit wheel spin. Adjust your
driving accordingly.

Use your anti-lock braking system when you need to. With anti-lock, you
can steer and brake at the same time. In many emergencies, steering can
help
you more than even the very best braking.
STEEMNG
Power Steering
If you lose power steering assist because the engine stops or the system is
not functioning, you can steer but it
will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on the news
happen on curves. Here’s why:
Experienced driver or beginner, each
of us is subject to the same laws of
physics when driving on curves. The traction of the tires against the road
surface makes it possible for the vehicle to change its path when you turn
the front wheels. If there’s no traction, inertia
will keep the vehicle going
in the same direction. If you’ve ever tried to steer a vehicle on wet ice,
you’ll understand this.
The traction you can get
in a curve depends on the condition of your tires
and
the road surface, the angle at which the curve is banked, and your
speed. While you’re in a curve, speed is the one factor
you can control.
Suppose you’re steering through a sharp curve. Then you suddenly
accelerate. Both control systems
-- steering and acceleration -- have to do
their work where the tires meet the road. Adding the sudden acceleration
can demand too much
of those places. You can lose control.

Let’s review what driving experts say about what happens when the three
control systems (brakes, steering and acceleration) don’t have enough
friction where the tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer and constantly seek
an escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle. Defensive drivers avoid
most skids by taking reasonable care suited to existing conditions, and by
not “overdriving” those conditions. But skids are always possible.
The three types of skids correspond to your Cadillac’s three control
systems. In the braking skid your wheels aren’t rolling. In the steering or
cornering skid, too much speed or steering in a curve causes tires to slip
and lose cornering force. And in
the acceleration skid too much throttle
causes the driving wheels to spin.
A cornering skid is best handled by easing your foot off the accelerator
pedal.
If you have the traction control system, remember: It helps avoid only the
acceleration skid.
If you do not have traction control, then an acceleration skid is also best
handled by easing your foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the accelerator pedal and
quickly steer the way you want the vehicle to
go. If you start steering
quickly enough, your vehicle may straighten out. Always be ready for a
second skid if
it occurs.
Of course, traction is reduced when water, snow, ice, gravel, or other
material is on the road. For safety, you’ll want to slow down and adjust
your driving to these conditions. It is important to slow down
on slippery
surfaces because stopping distance will be longer and vehicle control
more limited.

Downloaded from www.Manualslib.com manuals search engine What’s the worst time for this? “Wet ice.” Very cold snow or ice can be
slick and hard to drive on. But wet ice can be even more trouble because
it may offer the least traction of all.
You can get “wet ice” when it’s about
freezing
(32’F; O°C) and freezing rain begins to fall. Try to avoid driving
on wet ice until salt and sand crews can get there.
Whatever the condition
-- smooth ice, packed, blowing or loose snow --
drive with caution.
If you have the traction control system, it will improve your ability to
accelerate when driving on a slippery road. Even though your vehicle has
a traction control system, you’ll want to slow down and adjust your
driving to the road conditions. See “Traction Control System” in the
Index.
If you don’t have the traction control system, accelerate gently. Try not to
break the fragile traction.
If you accelerate too fast, the drive wheels will
spin and polish the surface under the tires even more.
Your anti-lock brakes improve your ability to make a hard stop on a
slippery road. Even though you have the anti-lock braking system, you’ll
want to begin stopping sooner than you would
on dry pavement. See
“Anti-lock” in the Index.
Allow greater following distance on any slippery road.

Downloaded from www.Manualslib.com manuals search engine Treadwear
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
(1 1/2) times as well on the government course as a tire graded
100. The relative performance of tires depends upon the actual
conditions
of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices and differences
in road characteristics and climate.
Traction - A, B, C
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 conditions on specified government test surfaces
sf asphalt
and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight-ahead) traction tests and does not include cornering (turning)
traction.
Temperature = A, B, C
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 laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire €ailure. The grade
C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard
No. 109. Grades B and A represent higher levels of
performance
on the laboratory test wheel than the minimum required by
law.
Warning: The temperature grade for this tire
is established for a tire that
is properly inflated and not overloaded. Excessive speed, underinflation,
or excessive loading, either separately or
in combination, can cause heat
buildup and possible tire failure.
These grades are molded on the sidewalls of passenger car tires.
