Downloaded from www.Manualslib.com manuals search engine Speed Sensitive Steering (SSS)
This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at a lower speed for increased
maneuverability and parking ease. As your vehicle speed increases, the
steering effort is also increased proportionately. At highway speeds the
amount
of steering effort is increased to provide a manual like steering
feel for maximum control and enhanced vehicle stability.
Road Sensing Suspension
The Road Sensing Suspension automatically controls the ride of your
vehicle. The system controls damping forces in the
shock absorbers and
struts in response to various road and driving conditions. The system is
capable
of making these changes within milli-seconds.
The Road Sensing Suspension controller is a computer used to control
and monitor the system. The computer receives inputs from vertical
acceleration sensors, wheel to body position sensors, vehicle speed
sensor, lift and dive signals, and determines optimum strut valving or
(suspension stiffness) for your current operating conditions. The
computer also receives feedback from the various components to
determine proper system operation. If the computer receives an incorrect
feedback from the system, an error code will be set in memory and a
“SERVICE
RIDE CONTROL’ message will display on the Driver
Information Center. If this message should appear, have your vehicle
serviced at your Cadillac dealer at your earliest convenience.

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. If one of the wheels is
about
to stop rolling, the computer will separately work 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 speea ana
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
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 (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 turn the cruise
control back on. (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.

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. Unless
you have traction
control and the system is on, adding the sudden acceleration can demand
too much of those places. You can lose control.
182

Downloaded from www.Manualslib.com manuals search engine 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.
A cornering skid and an acceleration skid are 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 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.
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

I
NOTICE:
Pulling a trailer improperly can damage your vehicle and result\

in costly repairs not covered by your warranty.
To pull a trailer
correctly,
follow the advice in this section.
Your Cadillac is a passenger vehicle. It was not designed for many of the
demands that trailer towing can add. Trailer towing can change the way
your vehicle performs on the road. It brings new forces into play and can
add plenty
of strain and stress to your vehicle.
Load pulling components such as the engine, transaxle, wheel assemblies,
and tires are forced to work harder against the drag of the added weight.
The engine
is required to operate at relatively higher speeds and under
greater loads, generating extra heat. Trailer towing adds considerably to
wind resistance increasing the pulling requirements.
All of that means changes in:
Handling
Durability
Fuel Economy
You may decide not to pull a trailer but meet your load carrying needs in
some other way.
203

Downloaded from www.Manualslib.com manuals search engine During your trip, check occasionally to be sure that the load is secure,
and that the lights and any trailer brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you would when
driving your vehicle without a trailer. This can help you avoid situations
that require heavy braking,and sudden turns.
Passing
You’ll need more passing distance up ahead when you’re towing a trailer.
And, because you’re a good deal longer, you’ll need to go much farther
beyond the passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move that hand to the left. To move the trailer to
the right, move your hand
to the right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns than normal. Do
this so your trailer won’t strike soft shoulders, curbs, road signs, trees, or
other objects. Avoid jerky or sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a different turn signal
flasher and extra wiring. The green arrows on your instrument panel will
flash whenever you signal a turn or lane change. Properly hooked up, the
trailer lights will also flash, telling
other drivers you’re about to turn,
change lanes or stop.
When towing
a trailer, the green arrows on your instrument panel will
flash for turns even if the bulbs on the trailer are burned out. Thus, you
may think drivers behind you are seeing your signal when they are not.
It’s important to check occasionally to be sure the trailer bulbs are still
working.

IF A TIRE GOES FLAT
It’s unusual for a tire to “blow out” while you’re driving, especially if you
maintain your tires properly. If air goes out of a tire, it’s much more likely
to leak out slowly. But
if you should ever have a “blowout,” here are a
few tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that pulls the vehicle
toward that side. Take your foot
off the accelerator pedal and grip the
steering wheel firmly. Steer
to maintain lane position, then gently brake
to a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a skid and may
require the same correction you’d use in a skid. In any rear blowout,
remove your foot from the accelerator pedal. Get the vehicle under
control by steering the way you want the vehicle to go. It may be
very
bumpy and noisy, but you can still steer. Gently brake to a stop, well off
the road if possible.
If a tire goes flat, the next section shows how to use your jacking
equipment to change a flat tire safely.
