1993 CADILLAC ELDORADO Tire

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. Tha\
t means
you can lose control of your vehicle.
BRAKING
Braking action involves p- 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

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 re\
ar 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.

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.
Try to adjust your speed so you can “drive” through the curve. Maintain a
reasonable, steady speed. Wait to accelerate until you are out
of the
curve, and then accelerate gently into the straightaway.
When you drive into a curve at night, it’s harder to see the road ahead of
you because it bends away from the straight beams of your lights. This is
one good reason
to drive slower.

You may find sometime that your right wheels have dropped off the edge
of a road onto the shoulder while you’re driving.
If the level of the shoulder is only slightly below the pavement, recovery
should be fairly easy. Ease off the accelerator and then, if there is nothing
in the way, steer
so that your vehicle straddles the edge of the pavement.
You can turn the steering wheel up to
1/4 turn until the right front tire
contacts the pavement edge. Then turn your steering wheel to go straight
down the roadway.
If the shoulder appears to be about four inches
(100 mm) or more below
the pavement, this difference can cause problems. If there is not enough
room to pull entirely onto the shoulder and stop, then follow the same
procedures. But if the right front tire scrubs against the side
of the
pavement, do
NOT steer more sharply. With too much steering angle, the
vehicle may jump back onto the road with
so much steering input that it
crosses over into the oncoming traffic before you can bring it back under
control.
Instead, ease
off again on the accelerator and steering input, straddle the
pavement once more, then try again.

If other cars are lined up to pass a slow vehicle, wait your turn. But
take care that someone isn’t trying to pass you as you pull out to pass
the slow vehicle. Remember to glance over your shoulder and check
the blind spot.
Check your mirrors
, glance over your shoulder, and start your left
lane change signal before moving out
of the right lane to pass. When
you are far enough ahead
of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal and move back
into the right lane. (Remember that your right outside mirror is
convex. The vehicle
you just passed may seem to be farther away from
you than it really is.)
Try not to pass more than one vehicle at a time on two-lane roads.
Reconsider before passing the
next vehicle.
Don’t overtake
a slowly moving vehicle too rapidly. Even though the
brake lights are not flashing, it may be slowing down or starting to
turn.
If you’re being passed, make it easy for the following driver to get
ahead of you. Perhaps you can ease a little to the right.
LOSS OF 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.

Downloaded from www.Manualslib.com manuals search engine A cornering skid and an acceleration skid are best handled by easing your
foot
off the accelerator pedal.
If your vehicle starts to slide (as when you turn a corner on a wet, snow-
or ice-covered road), ease your foot off the accelerator pedal as soon as
you
feel the vehicle start to slide. Quickly steer the way you want the
vehicle to go.
If you start steering quickly enough, your vehicle will
straighten out. As it does, straighten the front wheels.
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.
While driving on a surface with reduced traction, try your best to avoid
sudden steering, acceleration,
or braking (including engine braking by
shifting to
a lower gear). Any sudden changes could cause the tires to
slide. You may not realize the surface is slippery until your vehicle is
skidding. Learn to recognize warning clues
-- such as enough water, ice or
packed snow
on the road to make a “mirrored surface” -- and slow down
when you have any doubt.
Remember: Any anti-lock braking system
(ABS) helps avoid only the
braking skid. Steer the way you want to go.
DIWTNG AT NIGHT
188

Downloaded from www.Manualslib.com manuals search engine Night driving is more dangerous than day driving. One reason is that
some drivers are likely to be impaired
-- by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.

Drive defensively. Remember, this is the most dangerous time.
Don’t drink and drive. (See “Drunken Driving” in the Index for more
on this problem.)
Adjust your inside rearview mirror to reduce the glare from headlights
behind you.
Since you can’t see as well, you may need to slow down and keep more
space between you and other vehicles. It’s hard to tell how fast the
vehicle ahead is going just by looking at its taillights.
Slow down, especially on higher speed roads. Your headlights can light
up only
so much road ahead.
In remote areas, watch
for animals.
If you’re tired, pull off the road in a safe place and rest.
Night Vision
No one can see as well at night as in the daytime. But as we get older
these differences increase.
A 50-year-old driver may require at least twice
as much light to see the same thing
at night as a 20-year-old.
What you do in the daytime can
also affect your night vision. For
example, if you spend the day
in bright sunshine you are wise to wear
sunglasses. Your eyes will have
less trouble adjusting to night.
But if you’re driving, don’t wear sunglasses at night. They may cut down
on glare from headlights, but they also make a lot
of things invisible that
should remain visible
- such as parked cars, obstacles, pedestrians, or
even trains blocking railway crossings. You may want to put on your
sunglasses after you have pulled into a brightly-lighted service or
refreshment area. Eyes shielded from that glare may adjust more quickly
to darkness back on the road. But be sure to remove your sunglasses
before you leave the service area.
You can be temporarily blinded by approaching lights. It can take a
second or
two, or even several seconds, for your eyes to readjust to the
189

Downloaded from www.Manualslib.com manuals search engine Just as your headlights should be checked regularly for proper aim, so
should your eyes be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and aren’t even aware of it.
DRn/lNG IN THE RAIN
Rain and wet roads can mean driving trouble. On a wet road you can’t
stop, accelerate or turn as well because your tire-to-road traction isn’t as
good
as on dry roads. And, if your tires don’t have much tread left, you’ll
get even less traction.
It’s always wise to go slower and be cautious if rain starts to fall while you
are driving. The surface may get wet suddenly when your reflexes are
tuned for driving on dry pavement.
The heavier the rain, the harder it is to see. Even if your windshield wiper
blades are
in good shape, a heavy rain can makc it harder to see road
signs and traffic signals, pavement markings, the edge
of the road, and
even people walking. Road spray can often be worse for vision than rain,
especially
if it comes from a dirty road.
So it is wise to keep your wiping equipment in good shape and keep your
windshield washer tank filled. Replace your windshield wiper inserts
when they show signs of streaking or missing areas on the windshield,
or
when strips of rubber start to separate from the inserts.
