Steering Tips-Driving on Curves
154
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 jaws 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 banlted, 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 apply
the brakes. Both control systems-
steering and braking-have to do their
work where the tires meet the road.
Unless you have four-wheel anti-lock
brakes, adding the hard braking can
demand too much at those places.
You
can lose control.
The same thing can happen if you’re
steering through a sharp curve and you
suddenly accelerate. Those two control
systems-steering and acceleration-
can overwhelm those places where the
tires meet the road and make you lose
control.
What should you do if this ever
happens? Let up on the brake or
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.
When you drive into a curve at night,
it’s harder
to see the road ahead of you
because it bends away from the straight
beams of your lights. This is one good
reason to drive slower.

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 and an acceleration
skid are best handled by easing your
foot off the accelerator pedal.
If your
vehicle starts to slide (as when you turn
a corner on a wet, snow- or ice-covered road),
ease your foot
off the accelerator
pedal as soon as you feel the vehicle
start to slide. Quickly steer the way you
want the vehicle to go.
If you start
steering quickly enough, your vehicle
will straighten out.
As it does,
straighten the front wheels.
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
1
traction, try your best to avoid sudden
steering, acceleration, or braldng (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.
If you have the anti-lock braking
system, remember: It helps avoid only
the braking skid.
If you do not have
anti-lock, then in a braking skid (where
the wheels are no longer rolling),
release enough pressure on the brakes
to get the wheels rolling again. This
restores steering control. Push the
brake pedal down steadily when you
have to stop suddenly. As long as the
wheels are rolling, you will have
steering control. Steer the way you
want to go.

Driving at Night
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. Remember, this is
the most dangerous time.
Don’t drink and drive. (See the Index
under Drunken Driving for more on
this problem.)
Adjust your inside rearview mirror to
reduce the glare from headlights
behind you.
Since you can’t see as well, you may
need to slow down and keep more
space between you and other vehicles.
It’s hard to tell how fast the vehicle
ahead is going just by looking at its
taillights.

In remote areas, watch for animals.
If you’re tired, pull off the road in a
safe place and rest.

Driving a Long Distance
Although most long trips today are
made on freeways, there are still many
made on regular highways.
Long-distance driving on freeways and
regular highways is the same
in some
ways. The trip has to be planned and
the vehicle prepared, you drive at
higher-than-city speeds, and there
are
longer turns behind the wheel. You’ll
enjoy your trip more if you and your
vehicle are in good shape. Here are
some tips for a successful long trip.
Before Leaving on a Long Trip
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 Oldsmobile 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:

Hill 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
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 laow 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

trips safer and more enjoyable.
Keep your vehicle in good shape.

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

vehicle is passing you and doesn’t
have enough room, slow down to
make it easier for the other vehicle to
get by.

Do not tow a trailer if you have a
convertible with the 3.4L VIN Code X
engine.
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
If you do, here are some important
points.
There are many different laws having
to do with trailering. Make sure your
rig
will be legal, not oplly where you
live but also where you’ll be driving.
A
good source for this information can
be state or provincial police.
Consider using a sway control. You
can ask a hitch dealer about sway
controls.
Don’t tow a trailer at all during the
first
500 miles (800 km) your new
vehicle is driven. Your engine, axle or other parts could be damaged.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is
an important weight to measure
because it affects the total capacity
weight of your vehicle. The capacity
weight includes the curb weight of the
vehicle, any cargo you may carry in it,
and the people who
will be riding in
the vehicle. And
if you will tow a
trailer, you must subtract the tongue
load
from your vehicle’s capacity
weight because your vehicle
will be
carrying that -weight, too. See the
Index under Loading Your Vehicle for
more information about your vehicle’s
maximum load capacity. The
trailer tongue
(A) should weigh
10% of the total loaded trailer weight
(B) . After you’ve loaded your trailer,
weigh the trailer and then the tongue,
separately, to see
if the weights are
proper.
If they aren’t, you may be able
to get them right simply by moving
some items around in the trailer.
Total Weight on Your Vehicle’s
Tires
Be sure your vehicle’s tires are inflated
to the limit for cold tires.
You will find
these numbers
on the Certification
label at the rear edge of the driver’s
door or on the inside
of the trunk lid.
See the
Index under Tire L0adin.g.
Then be sure you don’t go over the
GVW limit for your vehicle.
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:
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 the
Index under
Carbon Monoxide in Exhaust. Dirt
and water can, too.
