1993 CADILLAC DEVILLE engine

Downloaded from www.Manualslib.com manuals search engine Sometimes, as when you’re driving on snow or ice, it’s easy to ask more of
those control systems than the tires and road can provide. That means
you can lose control
of your vehicle.
BRAKING
Braking action involves perception time and reaction time.
First, you have to decide to push on the brake pedal. That’s perception
- time. Then you have to bring up your foot and do it. That’s reaction time.
Average reaction time is about 3/4 of a second. But that’s only an
average. It might be less with one driver and as long as
two or three
seconds or more with another. Age, physical condition, alertness,
coordination, and eyesight all play
a part. So do alcohol, drugs and
frustration. But even in 3/4
of a second, a vehicle moving at 60 mph (100
km/h) travels 66 feet (20 m). That could be a lot of distance in an
emergency,
so keeping enough space between your vehicle and others is
important.
And, of course, actual stopping distances vary greatly
with the surface of
the road (whether it’s pavement or gravel); the condition
of the road
(wet, dry, icy); tire tread; and the condition
of your brakes.
Most drivers treat their brakes with care. Some, however, overwork the
braking system with poor driving habits.
Avoid needless heavy braking. Some people drive in spurts -- heavy
acceleration followed by heavy braking
-- rather than keeping pace

between hard
stops. Your brakes will wear out much faster if you do a
lot
of heavy braking.
a Don’t “ride” the brakes by letting your left foot rest lightly on the
brake pedal while driving.
CAUTION:
“Riding” your braws can cause them to overheat to the point
that they won’t work well. You might not be able to stop your
vehicle in time to avoid an accident.
If you “ride” your brakes,
they will get
so hot they will require a lot of pedal force to slow
you down. Avoid “riding” the brakes.

Downloaded from www.Manualslib.com manuals search engine If you keep pace with the traffic and allow realistic following distances,
you
will eliminate a lot of unnecessary braking. That means better
braking and longer brake life.
If your engine ever stops while you’re driving, brake normally but
don’t pump your brakes.
If you do, the pedal may get harder to push
down. If your engine stops, you will still have some power brake assist.
But you will use
it when you brake. Once the power assist is used up, it
may take longer
to stop and the brake pedal will be harder to push.
Anti-Lock Brakes (ABS)
Your Cadillac has an advanced electronic braking system that will help
prevent skidding.
This light on the
instrument panel will
go on when you start
your vehicle.

Here's how anti-lock works. Let's say the road is wet. You're driving
safely. Suddenly an animal jumps out in front
of you.
You slam on the brakes. Here's what happens with ABS.
A computer senses that wheels are slowing down. The computer
separately works the brakes at each front wheel and at the rear wheels.
The anti-lock system can change the brake pressure faster than any driver
could. The computer
is programmed to make the most of available tire
and road conditions.
-You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on wheel speed and
controls braking pressure accordingly.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
I 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
t- lug ~OU 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.
When you start your vehicle and begin to drive away,
you may hear a
momentary motor or clicking noise. And you may even notice that your
brake pedal moves a little while this is going
on. This is the ABS system
testing itself. You may also hear this during
a hard stop.
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 traction control
system works at low speeds only, such as when you accelerate from
a stop.
It applies brake pressure to an individual wheel that the system senses is
about to spin.

Disc Brake Wear Indicators
Your Cadillac has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a high-pitched
warning sound when the brake pads are worn and new pads are needed.
The sound may come and
go or be heard all the time your vehicle is
moving (except when you are pushing on the brake pedal firmly).
A CAUTION
The brake wear waming sound means thgt sooner or later your
brakes won’t work well. That could lead to an accident. when
you hear the brake wear warning sound, have your vehicle
serviced. 5-

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.
Rear Drum Brakes
Your rear drum brakes don’t have wear indicators, but if you ever hear a
rear brake rubbing noise, have the rear brake linings inspected.
Also, the
rear brake drums should be removed and inspected each time the tires
are removed for rotation or changing. When
you have the front brakes
replaced, have the rear brakes inspected, too.
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
there is a rapid increase in pedal travel. This could be a sign of brake
trouble.
Brake Adjustment
Every time you make a moderate brake stop, your 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.
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.

If you lose power steering assist because the engine stops or the system
fails to function, 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.
Those
two control systems -- steering and acceleration -- can overwhelm
those places where the tires meet the road and make you lose control.
What should you do if this ever happens? Let up on the accelerator
pedal, steer the vehicle the way you want it to go, and slow down.
Speed limit signs near curves warn that you should adjust your speed.
Of
course, the posted speeds are based on good weather and road
conditions. Under less favorable conditions you’ll want to go slower.
If you need to reduce your speed as you approach a curve, do it before
you enter the curve, while your front wheels are straight ahead.
