do, and there are some things you must not do.
First, here’s what you
should do:
Push the brake pedal to stop the vehicle and keep
it
from rolling backwards. Also, apply the parking brake.
If your engine is still running, shift the transmission
to REVERSE (R), release the parking brake, and
slowly back down the hill in REVERSE
(R).
If your engine has stopped running, you’ll need to
restart
it. With the brake pedal depressed and the
parking brake still applied, shift the transmission to
PARK (P) and restart the engine. Then, shift
to
REVERSE (R), release the parking brake, and
slowly back down the hill as straight as possible
in
REVERSE (R).
As you are backing down the hill, put your left hand
on the steering wheel at the 12 o’clock position. This
way, you’ll be able to tell
if your wheels are straight
and maneuver as you back down. It’s best that you
back down the
hill with your wheels straight rather
than in the left or right direction. Turning the wheel
too far to the
left or right will increase the possibility
of a rollover. Here are some things
you
must not do if you stall, or are
about
to stall, when going up a hill.
Never attempt to prevent a stall by shifting into
NEUTRAL
(N) to “rev-up7’ the engine and regain
forward momentum. This won’t work. Your vehicle
will roll backwards very quickly and you could go
out
of control.
Instead, apply the regular brake to stop the
vehicle. Then apply the parking brake. Shift to
REVERSE (R), release the parking brake, and
slowly back straight down.
Never attempt to turn around if you are about to stall
when going up a
hill. If the hill is steep enough to
stall your vehicle, it’s steep enough to cause you to
roll over
if you turn around. If you can’t make it up
the hill, you must back straight down the hill.
Suppose, after stalling, I try to back down the hill
and decide
I just can’t do it. What should I do?
A: Set the parking brake, put your transmission in
PARK (P) and
turn off the engine. Leave the
vehicle and go get some help. Exit on the uphill
side and stay clear of the path the vehicle would
take if it rolled downhill.

Driving Downhill
When off-roading takes you downhill, you’ll want to
consider
a number of things:
How steep is the downhill? Will I be able to maintain
vehicle control?
What’s the surface like? Smooth? Rough? Slippery?
Hard-packed dirt? Gravel?
Are there hidden surface obstacles? Ruts?
Logs? Boulders?
What’s at the bottom of the hill? Is there a hidden
creek bank or even
a river bottom with large rocks?
If you decide you can go down a hill safely, then try to
keep your vehicle headed straight down, and use
a low
gear. This way, engine drag can help your brakes and
they won’t have to do all the work. Descend slowly,
keeping your vehicle under control at all times.
Heavy braking when going down a hill can cause
your brakes to overheat and fade. This could cause loss
of control and a serious accident. Apply the
brakes lightly when descending a hill and use a low gear to keep vehicle speed under control.
Are there
some things I should not do when
driving down a hill?
A: Yes! These are important because if you ignore them
you could lose control and have
a serious accident.
When driving downhill, avoid turns that take you
across the incline
of the hill. A hill that’s not too
steep to drive down may be too steep
to drive across.
You could roll over if you don‘t drive straight down.
Never go downhill with the transmission in
NEUTRAL
(N). This is called “free-wheeling.” Your
brakes will have to do all the work and could
overheat and fade.

&: Am I likely to stall when going downhill?
A: It’s much more likely to happen going uphill. But if

it happens going downhill, here’s what to do.
Stop your vehicle by applying the regular brakes.
Apply the parking brake.
Shift to PARK
(P) and, while still braking, restart
the engine.
Shift back to a low gear, release the parking brake,
and drive straight down.
If
the engine won’t start, get out and get help.
Driving Across an Incline
Sooner or later, an off-road trail will probably go across
the incline of a hill.
If this happens, you have to decide
whether
to try to drive across the incline. Here are some
things
to consider:
0
0
0
A hill that can be driven straight up or down may be
too steep to drive across. When you
go straight up or
down a hill,
the length of the wheel base (the
distance
from the front wheels to the rear wheels)
reduces the likelihood the vehicle will tumble end
over end.
But when you drive across an incline, the
much more narrow track width (the distance between
the left and right wheels) may not prevent the vehicle
from tilting and rolling over. Also, driving across an
incline puts more weight on the downhill wheels.
This could cause a downhill slide or a rollover.
Surface conditions can be a problem when you drive
across a hill. Loose gravel, muddy spots, or even wet
grass can cause your tires to slip sideways, downhill.
If the vehicle slips sideways, it can hit something
that
will trip it (a rock, a rut, etc.) and roll over.
Hidden obstacles can make the steepness
of the
incline even worse. If you drive across a rock with
the uphill wheels, or
if the downhill wheels drop into
a rut or depression, your vehicle can tilt even more.

Driving in Water
Light rain causes no special off-road driving problems.
But heavy rain can mean flash flooding, and flood
waters demand extreme caution.
Find out how deep the water is before
you drive through
it. If it’s deep enough to cover your wheel hubs, axles or
exhaust pipe, don’t try it
-- you probably won’t get
through.
Also, water that deep can damage your axle
and other vehicle parts.
If the water isn’t too deep, then drive through it
slowly. At fast speeds, water splashes
on your ignition
system and your vehicle can stall. Stalling can also
occur if you get your tailpipe under water. And,
as long
as your tailpipe is under water, you’ll never be able to
start your engine. When you go through water,
remember that when your brakes get wet,
it may take
you longer to stop. Driving through rushing water can be dangerous.
Deep water can sweep your vehicle downstream
and you and your passengers could drown.
If it’s
only inches deep, it can still wash away the
ground from under your tires, and you could lose
traction and roll the vehicle over. Don’t drive
through rushing water.
See “Driving Through Water” in the Index for more
information on driving through water.
ProCarManuals.com

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 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.
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

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. 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 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? First, be
aware that
it can happen.
Then here are some tips:
e
e
e Make sure your vehicle is well ventilated, with a
comfortably cool interior.
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.
ProCarManuals.com

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 fluid
levels and also
the brakes, tires, cooling system and
transmission. These parts can work hard
on
mountain roads.
0 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.
I A CAUTION:
I
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.
fi CAUTION:
Coasting downhill in NEU (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.
0 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.
0 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.
