brakes OLDSMOBILE SILHOUETTE 1995 User Guide

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 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 feel the system
working, or you may notice some noise, but this
is
normal.
If your vehicle has the traction control system, the
LOW TRACTION light will come on when your
anti-lock system
is adjusting brake pressure to help
avoid a braking skid. See “Low Traction Light” in
the Index.

Traction Control System
(Option:
3800 V6 Engine)
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 to limit wheel spin.
The LOW TRACTION light will come on when your
traction control system is limiting wheel spin. See
“Low Traction Light” 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.)
TCS
The TCS warning light will come on to let you know if
there’s a problem with your traction control system.
See “Traction Control System Warning Light’’ in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.

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 Oldsmobile can perform very well in emergencies
like these. First apply your brakes. (See “Braking in
Emergencies” earlier
in this section.) It is better to
remove as much speed as you can 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.
The fact that such emergency situations are always
possible is a good reason
to practice defensive driving at
all times and wear safety belts properly.
Off-Road Recovery
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.

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 lamps 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
Oldsmobile’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, or if the system

Whatever the condition -- smooth ice, packed, blowing
or loose snow -- drive with caution.
If you have the traction control system, keep the system
on. It will improve your ability to accelerate when
driving on a slippery road. Even though your vehicle has
a traction control system, you’ll want to slow down and
adjust your driving
to the road conditions. See “Traction
Control System”
in the Index.
If you don’t have the traction control system, accelerate
gently. Try not to break the fragile traction.
If you
accelerate too fast, the drive wheels will spin and polish
the surface under the tires even more. Your
anti-lock brakes improve your ability to make a
hard stop on a slippery road. Even though
you have an
anti-lock braking system, you’ll want to begin stopping
sooner than
you would on dry pavement. See
“Anti-Lock’ in the Index.
Allow greater following distance on any slippery
road.
Watch for slippery spots. The road might be fine
until you hit a spot that’s covered with ice. On an
otherwise clear road, ice patches may appear in
shaded areas where the sun can’t reach: around
clumps
of trees, behind buildings, or under bridges.
Sometimes the surface
of a curve or an overpass may
remain icy when the surrounding roads are clear.
If
you see a patch of ice ahead of you, brake before you
are on it. Try not to brake while you’re actually
on
the ice, and avoid sudden steering maneuvers.

Safety Chains Driving with a Trauer
You
should always attach chains between your vehicle
and your trailer. Cross the safety chains under the tongue
of the trailer so that the tongue will not drop to the road
if
it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow the
manufacturer’s recommendation for attaching safety
chains and
do not attach them to the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never allow safety chains to drag
on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 pounds (450 kg)
loaded, then it needs its own brakes
-- and they must be
adequate. Be sure to read and follow the instructions for
the trailer brakes
so you’ll be able to install, adjust and
maintain them properly.
Because
you have anti-lock brakes, do not try to tap into
your vehicle’s brake system.
If you do, both brake
systems won’t work well,
or at all.

Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want
to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle
you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally
to be sure that the
load is secure, and that the lamps 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
1 NOTICE:
Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
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 extra
wiring and a different turn signal flasher (included in the
optional trailering package). The green arrows on your
instrument panel will flash whenever you signal a
turn
or lane change. Properly hooked up, the trailer lamps
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.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down
a long or steep downgrade. If you don’t shift
down, you might have
to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility of engine and transaxie overheating.
If you are towing a trailer that weighs more than
1,000 pounds (454 kg), and you have an automatic
transaxle with OVERDRIVE
(GO), you may prefer to
drive
in THIRD (D) instead of OVERDRIVE (0)
(or, as you need to, a lower gear). This will minimize
heat build-up and extend the life of your transaxle.

Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling
a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine
oil, belts, cooling system, and brake adjustment.
Each
of these is covered in this manual, and the Index
will help you find them quickly. If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically to see that
all hitch nuts and bolts
are tight.

When using concentrated washer fluid,
follow the manufacturer’s instructions for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and other parts of the washer system. Also,
water doesn’t clean as well as washer fluid.
Fill your washer fluid tank only
3/4 full
when it’s
very cold. This allows for
expansion, which could damage the tank if
it is completely full.
Don’t use radiator antifreeze in your
windshield washer. It
can damage your
washer system and paint.

Your brake master cylinder is here. It is filled with

There are only two reasons why the brake fluid level in
your master cylinder might go down.
The first is that the
brake
fluid goes down to an acceptable level during
nortnal brake lining wear. When new linings are put in,
the fluid level goes back up. The other reason is that
fluid is leaking out
of the brake system. If it is, YOU
