Downloaded from www.Manualslib.com manuals search engine TRACTION CONTROL (OPTION)
If you have this feature, this brake only Traction Control complements
your anti-lock braking system.
Traction Control regulates tire spin during low-speed acceleration and
steady driving.
The Traction Control Brake-Only System uses the same wheel speed
sensors used by your Anti-Lock Brake System
(ABS). When wheel slip is
detected by the wheel sensors, the electronic control module sends a
signal to the brake pressure modulator to apply pressure pulses to the
brakes. Traction is then maximized and your vehicle is enabled to
accelerate or continue driving with a controlled amount of tire slip. This
low-speed system controls tire slippage and is fully functional until you
reach
a speed of 24 mph and then the traction control is gradually phased
out as your vehicle reaches
30 mph. To keep you informed of changing
road conditions the “TRACTION
ACTIVE” telltale light will illuminate
when the system
is activated.
-
Because this is a brake only Traction Control system, it is designed to
protect your vehicles powertrain components. The system
will
temporarily by disabled should the brakes or transaxle reach excessively
high temperatures and prolonged use
of traction control. The
“TRACTION
OFF” telltale light in the instrument panel informs you
when this system is not in operation.
ELECTRONIC LEVEL CONTROL
This keeps your vehicle level.
The ignition does not have to be
“ON” for the level control to work. The
system consists
of an electronic height sensor, a small electric air
compressor, and air adjustable shock absorbers mounted on the rear
of
the vehicle.
If the system has a slight leak, the air compressor will run frequently for a
few seconds each time.
For a massive air leak, the air compressor will stay on
for approximately 7
minutes. You should see your dealer for service, but you can keep driving
your Cadillac.

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.

to pass
-- or if you get hit by a gust of wind. You could suddenly find
yourself out of control.
Hydroplaning doesn’t happen often. But it can if your tires haven’t much
tread
or if the pressure in one or more is low. It can happen if a lot of
water is standing on the road. If you can see reflections from trees,
telephone poles, or other vehicles, and raindrops “dimple” the water’s
surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There just isn’t
a hard
and fast rule about hydroplaning. The best advice is to slow down when it
is raining, and be careful.

Turn on your headlights -- not just your parking lights -- to help make
you more visible to others.
Look for hard-to-see vehicles coming from behind. You may want to
use your headlights even in daytime if it’s raining hard.
Besides slowing down, allow some extra following distance. And be
especially careful when you pass another vehicle. Allow yourself more
clear room ahead, and be prepared to have your view restricted by
road spray.
If the road spray is so heavy you are actually blinded, drop
back. Don’t pass until conditions improve. Going more slowly is better
than having an accident.
Use your defogger if it helps.
Have good tires with proper tread depth. (See “Tires”
in the Index.)

ON THE ROAD
Unless you are the only driver, it is good to share the driving task with
others. Limit turns behind the wheel to about
100 miles (160 km) or two
hours at a sitting. Then, either change drivers or stop for some
refreshment like coffee, tea or soft drinks and some limbering up. But do
stop and move around. Eat lightly along the
way. Heavier meals tend to
make some people sleepy.
On two-lane highways or undivided multilane highways that
do not have
___ controlled access, you’ll want to watch for some situations not usually
found on freeways. Examples are: stop signs and signals, shopping centers
with direct access to the highway, no passing zones and school zones,
vehicles turning left and right off the road, pedestrians, cyclists, parked
vehicles, and even animals.
HIGHFKAY HIPNOSIS
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.

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 your tire goes flat, the next section shows how to use your jacking
equipment to change a flat tire safely.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Storing a jack, a tire or otk --* equipment in the passengers
compartment
of the vehicle could cause injury. In a sudden stop
or collision loose equipment could strike someone. Store all
these in the proper place.
Now put all the equipment back in the cal
Just follow this drawing
COMPACT SPARE TIRE
Although the compact spare was fully inflated when your vehicle was
new, it can lose air after a time. Check the inflation pressure regularly. It
should be
60 psi (420 Wa). The compact spare is made to go up to 3,000
miles (5000 km), so you can finish your trip and have your full-size tire
repaired or replaced where you want.
Of course, it’s best to replace your
spare with a full-size tire as soon as you can. Your spare will last longer
and be in good shape in case you need it again.

Overloading your tires can cause overheating as a result of
too
much friction. You could have an air-out and a serious
accident. See “Loading Your Vehicle” in the Index.
Underinflated tires pose the
same danger as overloaded
tires. The resulting accident could cause serious iqjury.
Check all tires frequently to maintain the recommended
pressure. Tire pressure should be checked when your tires
are cold.
Overinflated tires are more likely to be cut, punctured, or
broken by a sudden impach such as whenyou hit a pothole.
Keep
tires at the recommended pressure.
Worn, old tires
can cause accidents. If your tread is badly
worn, or if your tires have been damaged, replace them.

Inflation - Tire Pressure
The Tire-Loading Information label which is on the driver’s door shows
the correct inflation pressures for your tires, when they’re
cold. “Cold”
means your vehicle has been sitting for at least three hours or driven no
more than a mile.

Downloaded from www.Manualslib.com manuals search engine When to Check Check your tires once a month or more. Your tire
pressure should be:
30 psi (210 kPa) (Front and Rear)
35 psi (241 kPa) (Coachbuilder Package - Front and Rear)
32 psi (220 kPa) (H.D. Livery - Front and Rear)
32 psi (220 kPa) (Touring Sedan - Front)
30 psi (210 kPa) (Touring Sedan - Rear)
Recommended tire sizes are:
P205/70R15 (Front and Rear)
P215/75R15 (Coachbuilder - Front and Rear)
0 P215/60R16 Goodyear GA (Touring Sedan)
0 T125/70D15 (Compact Spare)
T125/70R15 (Touring Sedan - Compact Spare)
Don’t forget your compact spare tire. It
should be at 60 psi (420 kPa).

Downloaded from www.Manualslib.com manuals search engine How to Check Use a good quality pocket-type gage to check tire
pressure. Simply looking at the tires will not tell you the pressure,
especially if you have radial tires
-- which may look properly inflated even
if they’re underinflated.
If your tires have valve caps, be sure to put them back on. They help
prevent leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
To make your tires last longer, have them inspected and rotated at the
mileages recommended in your Maintenance Schedule. See “Scheduled Maintenance Service” in the Index.
FRONT Use this rotation pattern.
After the tires have been rotated, adjust the front and rear inflation
pressure as shown on the Tire-Loading Information label. Make certain
that all wheel nuts are properly tightened.
See “Wheel Nut Torque” in the
Index.
