Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you can’t stop, accelerate or turn as well because your tire-to-road traction isn’t as
good
as on dry roads.
And,
if your tires don’t have much tread left, you’ll get
even less traction. It’s always wise to go slower and be
cautious
if rain starts to fall while you are driving. The
surface may get wet suddenly when your reflexes are
tuned
for driving on dry pavement.
The heavier the rain, the harder
it is to see. Even if your
windshield wiper blades are
in good shape, a heavy rain
can make
it harder to see road signs and traffic signals,
pavement markings, the edge
of the road and even
people walking.
It’s wise to keep your wiping equipment in good shape
and keep your windshield washer tank filled with
washer fluid. Replace your windshield wiper inserts
when they show signs of streaking or missing areas on
the windshield, or when strips of rubber start to separate
from the inserts.

Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen
if the road is wet enough and you’re
going fast enough. When your vehicle is hydroplaning,
it has little or no contact
with the road.
Hydroplaning doesn’t happen often.
But it can if your
tires do not have 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.
Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddles or
standing water, water can come in through your
engine’s air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody
of your vehicle. If you
can’t avoid deep puddles or standing water, drive
through them very slowly.
Some Other Rainy Weather Tips
0 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.
0 Have good tires with proper tread depth. (See
“Tires“
in the Index.)

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower at night.
When you want to leave the freeway, nwve to the proper
lane well
in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive on to
the next 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.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. lf 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 retailers all across North America. They'll
be ready and
willing to help if you need it.

Highway Hypnosis
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? Erst, be
aware that
it can happen.
Then here are some tips:
0 Make sure your vehicle is well ventilated, with a
comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead and
to the sides. Check your mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest, service
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway
as
an emergency.
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
your trips safer and more enjoyable. (See “Off-Road
Driving”
in the Index for information about driving
off-road.)
Keep your vehicle in good shape. Check all fl~lid
levels and also the brakes, tires. cooling system and
transmission. 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. Shift to a lower gear
when you go
down a steep or long hill.
A CAUTION:
If you don’t shift down, your brakes could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going
down
a hill. You could crash. Shift down to let
your engine assist your brakes on
a steep
downhill slope. Coasting
downhill in NEUTRAL
(N) or with the
ignition
off 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 would then
have poor braking or even none going down
a hill.
You could crash.
Always have your engine running
and your vehicle in gear when you go downhill.
Know how to go uphill. You may want to shift down to a
lower gear. The lower gears help cool your engine and
transmission, 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.
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.

Winter Driving
Here are some tips for winter driving:
0 Have your Oldsmobile in good shape for winter.
0 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
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.
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; OOC) and freezing rain begins to fall.
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 vehicle’s stability
when you 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.

Loading Your Vehicle
The Certification/Tire label is found on the driver’s door
edge, above the door latch. The label shows the size of
your original tires and the inflation pressures needed to
obtain the gross weight capacity
of your vehicle. This is
called the
Gross Vehicle Weight Rating (GVWR). The
GVWR includes the weight
of the vehicle, all occupants,
fuel, cargo and trailer tongue weight,
if pulling a trailer.
The Certification/Tire label also tells you the maximum
weights
for the front and rear axles, called Gross Axle
Weight Rating (GAWR).
To find out the actual loads on your
front and rear axles, you need to
go to a weigh
station and weigh your vehicle.
Your retailer can help
you
with this. Be sure to spread out your load equally on
both sides
of the centerline.
Never exceed the GVWR for your vehicle,
or the
GAWR for either the front
or rear axle.
If you do have a heavy load, you should spread it out.
Similar appearing vehicles may have different GVWR’s
and payloads. Please note
your vehicle’s
Certificationflire label or consult your retailer
for
additional details.
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can
break, or it can change the
way your vehicle
handles. These could cause you to lose control.
Also, overloading can shorten the life of
your vehicle.
