Downloaded from www.Manualslib.com manuals search engine The electronics and computerization which were
by Cadillac in the '70s came of age in the
'80s with Digital Fuel Injection and On-Board
1980, four wheel Anti-lock Brakes on
1986 models and Traction Control in the fall of 1989.
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,
The year 1993 saw the introduction
of the Northstar
system. The state
of the art system includes the 32 valve,
dual overhead camshaft, Northstar
4.6 liter V8 engine,
4T80-E electronically controlled automatic transaxle, road sensing suspension, speed sensitive steering, anti-lock brakes and traction control.
For more than nine decades Cadillac has been a leader in
and technical innovation. Now more than ever,
is "Creating a Higher Standard."

25 mph (40 b/h) or more without keeping your foot on
the accelerator. This can help on long trips. Cruise

you could lose control. Don’t
use cruise control on slippery roads.
If your vehicle is in cruise control when the traction
control system begins
to limit wheel spin, the cruise
control will automatically disengage. (See “Traction Control System” in
the Index.) When road conditions
allow you to safely use it again, you may turn the cruise
control back on.

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
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.
