Ant CADILLAC DEVILLE 1994 7.G Repair Manual
Page 197 of 399
Downloaded from www.Manualslib.com manuals search engine As you brake, your computer keeps receiving updates on wheel speed and
controls braking pressure accordingly.
Remember: 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 though you 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. You may hear the anti-lock pump or motor operate, and
feel the brake pedal pulsate, but this is normal.
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 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 (by shutting
off fuel injectors) 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 the system working, or you may notice some noise, 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 DISABLED” message will display on the Driver
Information Center if there’s a problem with your traction control system.
See “Driver Information Center Messages” in the Index. When this
message is displayed, the system will not limit wheel spin. Adjust your
driving accordingly.

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.
STEEMNG
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.
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. 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.
185
Page 199 of 399
Downloaded from www.Manualslib.com manuals search engine 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.
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.
Steering in Emergencies
There are times when steering can be more effective than braking. For
example, you come over a hill and find a truck stopped in your lane, or a
car suddenly pulls out from nowhere, or a child darts out from between
parked cars and stops right
in front of you. You can avoid these problems
by braking
-- if you can stop in time. But sometimes you can’t; there isn’t
room. That’s the time for evasive action
-- steering around the problem.
Your Cadillac can perform
very well in emergencies like these. First apply
your brakes. It is better to remove as much speed as yowan from a
possible collision. Then steer around the problem, to the left or right
depending on the space available.
An emergency like this requires close attention and a quick decision. If
you are holding the steering wheel at the recommended
9 and 3 o’clock
positions, you can turn it a full
180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and just as quickly
straighten the wheel once you have avoided the object. r

Page 202 of 399
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.
0 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.)
0 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

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.
A cornering skid is best handled by easing your foot off the accelerator
pedal.
If you have the traction control system, remember: It helps avoid only the
acceleration skid.
If you do not have traction control, 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.
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.

Page 204 of 399
Downloaded from www.Manualslib.com manuals search engine 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.
DRn/lNG ATNIGHT

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.

Downloaded from www.Manualslib.com manuals search engine One of the biggest problems with city streets is the amount of traffic on
them. You’ll want to watch out for what the other drivers are doing and
pay attention to traffic signals.
Here are ways to increase your safety in city driving:
0 Know the best way to get to where you are going. Get a city map and
plan your trip into an unknown part
of the city just as you would for a
cross-country trip.
0 Try to use the freeways that rim and crisscross most large cities. You’ll
save time and energy. (See the next section, “Freeway Driving.”)
Treat a green light as a warning signal. A traffic light is there because
the corner is busy enough to need it. When a light turns green, and
just before you start to move, check both ways for vehicles that have
not cleared the intersection or may be running the red light.

Mile for mile, freeways (also called thruways, parkways, expressways,
turnpikes, or superhighways) are the safest
of all roads. But they have
their own special rules.
The most important advice
on freeway driving is: Keep up with traffic and
keep to the right. Drive at the same speed most of the other drivers are
driving. Too-fast
or too-slow driving breaks a smooth traffic flow. Treat
the left lane on a freeway as a passing lane.
At the entrance there is usually a ramp that leads to the freeway.
If you
have a clear
view of the freeway as you drive along the entrance ramp,
you should begin to check traffic.
Try to determine where you expect to
blend with the flow.
Try to merge into the gap at close to the prevailing
speed. Switch
on your turn signal, check your mirrors and glance over
your shoulder as often as necessary.
Try to blend smoothly with the traffic
flow.
Once you are on the freeway, adjust your speed to the posted limit or to
the prevailing rate if it’s slower. Stay in the right lane unless you want to
pass.
Before changing lanes, check your mirrors.
Then use your turn signal.
Just before you leave the lane, glance quickly over your shoulder to make
sure there isn’t another vehicle in your “blind” spot.

Once you are moving on the freeway, make certain you allow a
reasonable following distance. Expect to move slightly slower at night.
When you want
to leave the freeway, move to the proper lane well in
advance.
If you miss your exit do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not to your sense of
motion. After driving for any distance at higher speeds, you may tend to
think you are going slower than you actually are.
BEFORE LEAVTNG ONA LONG THP
Make sure you’re ready. Try to be well rested. If you must start when
you’re not fresh
-- such as after a day’s work -- don’t plan to make too
many miles that first part
of the journey. Wear comfortable clothing and
shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it serviced and
maintained, it’s ready to
go. If it needs service, have it done before
starting out.
Of course, you’ll find experienced and able service experts in
Cadillac dealerships all across North America. They’ll be ready and
willing to help if
you need it.
Here are some things you can check before a trip:
0 Windshield Washer Fluid: Is the reservoir full? Are all windows clean
inside and outside?
Wiper Blades: Are they in good shape?
0 Fuel, Engine Oil. Other Fluids: Have you checked all levels?
Lights: Are they all working? Are the lenses clean?

tread good enough for long-distance driving? Are the tires all inflated
to the recommended pressure?
- Weather Forecasts: What’s the weamer outlook along your route?
Should you delay your trip a short time to avoid
a major storm
system?

HIGmAY HKPNOSIS
c_ Is there actually such a condition as “highway hypnosis”? Or is it just
plain falling asleep at the wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch
of road with the same scenery,
along with the hum of the tires on the road, the drone
of the engine, and
the rush
of the wind against the vehicle that can make you sleepy. Don’t
let it happen to you! If it does, your vehicle can leave the road in less than
a second, and you could crash and be injured.
What can you do about highway hypnosis? First, be aware that it can
happen. -_

Then here are some tips:
Make sure your vehicle is well ventilated, with a comfortably cool
interior.
Keep your eyes moving. Scan the road ahead and to the sides. Check
If you get sleepy, pull off the road into a rest, service, or parking area

and take a nap, get
some exercise, or both. For safety, treat drowsiness
on the highway as an emergency.
