1997 CADILLAC DEVILLE tires

Downloaded from www.Manualslib.com manuals search engine For the 1948 model, Cadillac introduced the legendary
tail fin which once more set the trend in automotive
styling for nearly two decades. This was closely
followed with the two door hardtop Coupe DeVille and
the industry's first modern overhead valve, high compression
V8 engine on the 1949 model.
Engineering innovations, conveniences and styling dominated the
'50s and '60s. Cruise control, automatic
climate control, tilt and telescoping steering wheels,
twilight sentinel and four door hard tops all debuted in
these years. In 1957 the Eldorado Brougham featured advances such as air suspension, memory seat,
automatic electric door locks, transistor radio, a brushed
stainless steel roof and low profile tires.

The Eldorado, introduced in 1953, was redesigned
for
1967 as the first front wheel drive personal luxury car.
The 472 cu. in.
V8 engine used in all Cadillacs in 1968
and 1969 was enlarged to
500 cu. in. for all 1970
through 1976 Eldorados. The Track Master
computerized skid control braking system option
debuted
on 1970 Eldorados.
A driver and passenger Air Cushion Restraint system (air bag) was available on all 1974,
1975 and
1976 Cadillacs.
Analog Electronic Fuel Injection was available, on 1975 Cadillacs and standard on the new international
size 1976 Seville. In 1978, the Trip Computer option
incorporated the first on-board microprocessor.

Vehicle Speed Limiter
This feature prevents your vehicle from exceeding
speeds that the tires are not rated for. When this
happens, the engine’s fuel supply is shut
off. When the
vehicle speed slows, the fuel supply will come on again. This gage
indicates the
engine speed in revolutions

(rpm).
1 NOTICE:
Do not operate the engine with the tachometer in
the red area or engine damage may occur.
Engine Speed Limiter
This feature prevents the engine from operating at too many

Downloaded from www.Manualslib.com manuals search engine Control of a Vehicle
You have three systems that make your vehicle go where
you want it to
go. They are the brakes, the steering and
the accelerator.
All three systems have to do their work
at the places where the tires meet the road.
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.
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. 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; the condition
of your brakes; the weight of the
vehicle and the amount
of brake force applied.

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. Refer to
“Traction Control System”
in the Index. What should
you do if this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want it
to go, and slow down.
If you have the DeVille Concours, you may see the
STABILITY
SYS ENGAGED message on the Driver
Information Center. See “Stability Engaged Message” in
the Index.
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.

Downloaded from www.Manualslib.com manuals search engine Do not get too close to the vehicle you want to
pass while you’re awaiting
an opportunity. For one
thing, following too closely reduces your area of
vision, especially if you’re following a larger
vehicle. Also, you won’t have adequate space if the
vehicle ahead suddenly slows or stops. Keep back a
reasonable distance.
0 When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and don’t
get too close. Time your move
so you will be
increasing speed as the time comes to move into the
other lane.
If the way is clear to pass, you will have a
“running start” that more than makes up for the
distance
you would lose by dropping back. And if
something happens to cause you to cancel your pass,
you need only slow down and drop back again and
wait for another opportunity.
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.

and move back into the right lane. (Remember that
your right outside mirror is convex. The vehicle you

it really is.)
0 Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.

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.

Downloaded from www.Manualslib.com manuals search engine 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.
Remember: Any traction control system helps avoid
only the acceleration skid.
If your traction control system is off, 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.
If you have the DeVille Concours, you may see the
STABILITY
SYS ENGAGED message on the Driver
Information Center. See “Stability Engaged Message’’ in
the Index.
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 brake system (ABS) helps
avoid only the braking skid.

Downloaded from www.Manualslib.com manuals search engine Driving in Rain and on Wet Roads
D
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 make
it harder to see road signs and traffic signals,
pavement markings, the edge of the road and even
people walking.
It’s wise to keep your windshield wiping equipment in
good shape and keep your windshield washer tank filled
with washer fluid. 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.
