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:

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.

After Off-Road Driving
Remove any brush or debris that has collected on the
underbody, chassis or under the hood. These
accumulations can be a fire hazard.
Driving at Night
After operation in mud or sand, have the brake linings
cleaned and checked. These substances can cause
glazing and uneven braking. Check the body structure,
steering, suspension, wheels, tires and exhaust system
for damage. Also, check the fuel lines and cooling
system for any leakage.
Your vehicle will require more frequent service due to
off-road use. Refer to the Maintenance Schedule for
additional information.
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 fdtigue.

Driving too fast through large water puddles or even
going through
some car washes can cause problems, too.
The water may affect your brakes. Try to
avoid puddles.
But if you can’t, try to
slow down before you hit them.
Wet brakes can cause accidents. They won’t worl
well in a quick stop and may cause pulling to one
side. You could lose control of the vehicle.
After driving through a large puddle
of water or
a car wash, apply your brake pedal lightly until
your brakes work normally.

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.

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.
0 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.

Payload
The payload capacity is shown on the CertificatiodTire
label. This
is the maximum load capacity that your
vehicle can carry. Be sure to include the weight of the
occupants as part
of your load. If you added any
accessories or equipment after your vehicle
left the
factory, remember to subtract the weight
of these things
from the payload. Your retailer can help you with this.
Add-on Equipment
When you carry removable items, you may need to put a
limit on how many people
you carry inside your vehicle.
Be sure to weigh your vehicle before you buy and install
the new equipment.
Your warranty doesn’t cover parts or
components that fail because of overloading.
Towing a Trailer
CAUTION:
If you don’t use the correct 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. Ask your Oldsmobile retailer
for advice and information about towing a trailer with your vehicle.

If you’ll be pulling a trailer that, when loaded, will
weigh more than 2,000 Ibs. (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 “Carbon Monoxide”
in the
Index). Dirt and water can, too.
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 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 lbs. (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.
Your trailer’s brake system can tap into the vehicle’s
hydraulic brake system only
if:
0 The trailer parts can withstand 3,000 psi
(20 650
kPa) of pressure.
0 The trailer’s brake system will use less than
0.02 cubic inch (0.3 cc) of fluid from your vehicle’s
master cylinder. Otherwise,
both braking systems
won’t work well. You could even lose your brakes.
If everything checks out this far, then make the brake
fluid tap at the port on the master cylinder that sends
fluid to the rear brakes.
But don’t use copper tubing for
this.
If you do, it will bend and finally break off. Use
steel brake tubing.

Driving with a Trailer
A CAUTION:
If you have a rear-most window open and you
pull
a trailer 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 “Engine Exhaust” in the Index.)
To
maximize your safety when towing a trailer:
a
a
a
Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
If exhaust does come into your vehicle
through
a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan on any speed. This will bring fresh,
outside air into your vehicle.
Do not use
MAX A/C because.it only recirculates the
air inside your vehicle. (See “Comfort
Controls” in the Index.)
L
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 yaurself 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.
