traction control CADILLAC DEVILLE 1996 7.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine The electronics and computerization which were
pioneered
by Cadillac in the '70s came of age in the
'80s with Digital Fuel Injection and On-Board
Diagnostics in
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,
Automobile Magazine.
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.

With cruise control, you can maintain a speed of about
25 mph (40 b/h) or more without keeping your foot on
the accelerator. This can help on long trips. Cruise
control does not work at speeds below about
25 mph
(40 km/h).
Cruise control shuts off when you apply your brakes.
A CAUTION:
e
e Cruise control can be dangerous where you
can’t drive safely at a steady speed.
So,
don’t use your cruise control on winding
roads
or in heavy traffic.
Cruise control can be dangerous on
slippery
roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and
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.

Downloaded from www.Manualslib.com manuals search engine Remember: Anti-lock doesn’t change the time you need
to get your foot
up to the brake pedal or always decrease
stopping distance. 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.
Using 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
Your vehicle has 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 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 or hear
the system working, 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 control system automatically comes on
whenever you
start your vehicle. To limit wheel spin,
especially
in slippery road conditions, you should
always leave the system on.
But you can turn the
traction control system off
if you ever need to.
(You should turn the system
off if your vehicle ever
gets stuck
in sand, mud, ice or snow. See “Rocking
Your Vehicle” in the Index.)

To turn the system off, press
the
TRAC OFF button

The TRACTION OFF message will display on the
Driver Information Center. If the system
is limiting
wheel spin when you press the button, the TRACTION
OFF message will display -- but the system won’t turn
off right away. It will wait until there’s no longer a
current need to limit
wheel spin.
You can
turn the system back on at any time by pressing
the button again. The TRACTION

should display briefly

Downloaded from www.Manualslib.com manuals search engine Braking in Emergencies
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.
Steering
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.
MAGNASTEER TM (Concours Only)
Your vehicle may be equipped with GM MAGNASTEER,
a system that continuously adjusts the effort you feel when
steering at
all vehicle speeds. It provides ease when
parking yet a fm, solid feel at highway speeds.
Speed Sensitive Steering (SSS)
(DeVille Only)
This system varies the amount of steering effort
proportionate to your vehicle speed. Steering is easier at
a lower speed for maneuvering and parking ease. As
your vehicle speed increases, the steering effort also
increases.
At highway speeds, the amount of steering
effort is increased
to provide manual-like steering for
maximum control and stability.
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.
