1993 OLDSMOBILE SILHOUETTE brake

If you are moving from an outside to a
center lane on a freeway having more
than two lanes, make sure another
vehicle isn’t about to move into the same spot. Look at the vehicles two lanes
over and watch for telltale signs:
turn
signals flashing, an increase in speed, or
moving toward the edge of the lane. Be
prepared
to delay your move.
Once you are moving on the freeway,
make certain you allow a reasonable
following distance. Expect
to move
slightly slower at night.
Leaving the Fkeeway
When you want to leave the freeway,
move to the proper lane well
in advance.
Dashing across lanes at the last minute
is dangerous.
If you miss your exit do
not, under any circumstances, stop and
back up. Drive on
to the next exit.
At each exit point is a deceleration lane.
Ideally it should be long enough for
you
to enter it at freeway speed (after
signaling, of course) and then do your
braking before moving onto the exit
ramp. Unfortunately, not
all deceleration
lanes are long enough-some are too
short for all the braking. Decide when
to start braking.
If you must brake on
the through lane, and if there is traffic
close behind you, you can allow a little extra time and flash your brake lights (in
addition to your
turn signal) as extra
warning that you are about
to slow
down and 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. For example,
40 mph (65 km/h)
might seem like only 20 mph (30 km/h).
Obviously, this could lead to serious
trouble on a ramp designed for
20 mph
(30 Mh)!

Hi// and Mountain Roads
Driving on steep hills or mountains is
different from driving in flat or rolling
terrain.
If you drive regularly in steep
country, or if you’re planning to visit
there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape.
Check all fluid levels and also the
brakes, tires, cooling system and
transaxle. These parts can work hard
on mountain roads.
Know how to go down hills. The most
important thing to
know is this: let
your engine do some of the slowing
down. Don’t make your brakes do it
all. Shift to a lower gear when you go
down a steep or long hill. That way,
you will slow down without excessive
use
of your brakes.
GAU I IUN
If you don’t shift down, your
brakes could get
so hot that I
they wouldn’t work well. You
1 would then have poor braking or
even none going down a hill. You
1 could crash. Shift down to let your
engine assist your brakes on a
steep downhill slope.
Coasting downhill in
N
C L (Neutral) or with the ignition
OII is dangerous. Your brakes will
have
to do all the work of slowing
down. They could get
so hot that
they wouldn’t work well. You
could crash. Always have your
engine running and your vehicle in
gear when you
go downhill.
I
Know how to go uphill. You may want
to shift down to a lower gear. The
lower gears help
cool your engine and
transaxle, and you can climb
the hill
better.
Stay in your own lane when driving on
two-lane roads in hills or mountains.
Don’t swing wide or cut across
the
center of the road. Drive at speeds that
let you stay
in your own lane. That
way, you won’t be surprised by
a
vehicle coming toward you in the
same lane.
It takes longer to pass another vehicle
when you’re going uphill. You’ll want
to leave extra room to pass. If a
ProCarManuals.com

vehicle is passing you and doesn't have
enough room, slow down to make
it
easier for the other vehicle to get by.
As you go over the top of a hill, be
alert. There could be something in
your lane, like a stalled car or an
accident.
You may see highway signs on
mountains that warn of special
problems. Examples are
long grades,
passing or no passing zones,
a falling
rocks area, or winding roads. Be alert
to these and take appropriate action.
problems. See the
Index under Winter
Driving.

Parking on Hills
Hills and mountains mean spectacular
scenery. But please be careful where you
stop
if you decide to look at the view or
take pictures.
Look for pull-offs or
parking areas provided for scenic
viewing.
Another part of this manual tells how to
use your parking brake (see the
Index
under Parking Brake). But on a
mountain or steep hill, you can do one
more thing. You can turn your front
wheels to keep your vehicle from rolling
downhill or out into traffic.
Here's how:
Parking Downhill
Turn your wheels to the right.
You don't have to jam your tires against
the curb,
if there is a curb. A gentle
contact
is all you need.
ProCarManuals.com

Torque Lock
If you are parking on a hill and you
don’t shift your transaxle into
P (Park)
properly, the weight of the vehicle may
put too much force on the parking pawl
in the transaxle. You may find it difficult
to pull the shift lever out of
P (Park).
This is called “torque lock.” To prevent
torque lock, always be sure
to shift into
P (Park) properly before you leave the
driver’s seat. To find out how, see the
Index under Shifting Into P (Park).
When you are ready to drive, move the
shift lever out of P (Park) before you
release the parking brake.
If torque lock does occur, you may need
to have another vehicle push yours a
little uphill to take some of the pressure
from the transaxle,
so you can pull the
shift lever out of
P (Park).
Winter Driving
Here are some tips for winter driving:
Have your Oldsmobile in good shape
for winter. Be sure your engine
coolant
mix is correct.
* Snow tires can help in loose snow, but
they may give you less traction on ice
than regular tires.
If you do not expect
to be driving in deep snow, but may
have to travel over ice, you may not
want
to switch to snow tires at all.
You may want to put winter
emergency supplies in your vehicle.
Include
an ice scraper, a small brush
or broom,
a supply of windshield
washer fluid, a rag,
some winter outer
clothing, a small shovel, a flashlight,
a
red cloth, and a couple of reflective
warning triangles. And,
if you will be
driving under severe conditions,
include a small bag
of sand, a piece of
old carpet or a couple of burlap bags
to help provide traction. Be sure you
properly secure these items
in your
vehicle.

Your Driving and the Road
Driving on Snow or Ice
Most of the time, those places where
your tires meet the road probably have
good traction.
However, if there is snow or ice
between your tires and the road, you can
have a very slippery situation. You’ll
have
a lot less traction or “grip” and
will need to be very careful.
What’s the worst time for this? “Wet
ice.” Very cold snow or ice can be slick
and hard
to drive on. But wet ice can be
even more trouble because it may offer
the least traction
of all. You can get wet
ice when it’s about freezing
(32°F; 0°C)
and freezing rain begins to fd. Try to
avoid driving on wet ice until salt and
sand crews can get there. Whatever the condition-smooth ice,
packed, blowing or loose snow-drive
with caution. 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 the anti-
lock braking system, you’ll want to
begin stopping sooner
than you would
on dry pavement.
See the Index under
Anti-Lock Brake System.
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.

Towing a Tmiler
I I If you don’t use the correct I
L L equipment and drive properly,
you can lose control when you pull
a trailer. For example, if the trailer
is too heavy, the brakes may not
work well-or even at all. You and
your passengers could be seriously
injured. Pull a trailer only
if you
have followed all the steps in this section. Your
Oldsmobile can tow a trailer. To
identify what the vehicle trailering
capacity is for your vehicle, you should
read the information in
Weight of the
Trailer
that appears later in this section.
But trailering
is different than just
driving your vehicle
by itself. Trailering
means changes
in handling, durability,
and fuel economy. Successful, safe
trailering takes correct equipment, and
it
has to be used properly.
That’s the reason for
this section, In it
are many time-tested, important
trailering tips and safety rules. Many of
these are important for your safety and
that of your passengers.
So please read
this section carefully before you pull a
trailer. 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. What’s more, the trailer adds
considerably to wind resistance, increasing the pulling requirements.
All
of that means changes in:
Handling
Durability
Fuel economy

If You Do Decide to Pull a Trailer
(CON X)
Hitches
It’s important to have the correct hitch
equipment. Crosswinds, large trucks
going by, and rough roads are a few
reasons why you’ll need the right hitch.
Here are some rules to follow:
If you’ll be pulling a trailer that, when
loaded, will weigh more than 2,000
pounds (900 kg), be sure to use a
properly mounted, weight-distributing hitch and sway control of the proper
size. This equipment is very important
for proper vehicle loading and good
handling when you’re driving.
Will you have to make any holes in the
body of your vehicle when you install
a trailer hitch?
If you do, then be sure
to seal the holes later when you remove
the hitch. If
you don’t seal them, deadly
carbon monoxide (CO) from your
exhaust can get into your vehicle. (See
Index under Carbon Monoxide in
Exhaust.) Dirt and water can, too.
The bumpers on your vehicle are not
intended for hitches. Do not attach
rental hitches or other bumper-type
hitches to them. Use only a frame-
mounted hitch that does not attach to
the bumper.
Safety Chains
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. 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,OOO
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.

1 Driving with a Trailer
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
so responsive as your vehicle
is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical
connector, lights, 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.
If you have a rear-most
window open and you pull a
mler with your‘vehicle, carbon
monoxide (CO) could come into
your vehicle. You can’t see or
smell CO. It can cause
unconsciousness or death (see the
Inh under Engine Exhausb). To I

a trailer:

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.
