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 secund, 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:
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 rearview 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.
4-22

If you drive regularly in steep count., or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
0 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 downhills. 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 = ~ ~ ~~ ~~ ~
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
hiIl. You could crash. Shift down to let
your engine assist your brakes on a steep
downhill slope.
0 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.
could be something in your lane, like a stalled car or
an accident.
0 As you go over the top of a hill, be alert. There
You may see highway signs on mountains that warn of
special problems. Examples are long grades, passiag or
no-passing zones, a falling rocks area or winding
roads. Be alert to these and take appropriate action.
4-23

Tie a red cloth to your vehicle to alert police that
you’ve been stopped by the snow.
0 Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill
you. You can’t see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to
time to be sure snow
doesn’t collect there.
Open a window just a little on the side of the
vehicle that’s away from the wind. This will help
keep
CO out.
You can run the engine to keep warm, but be careful.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need additional wiring. Check with your retailer. The green
arrows on your instrument panel will flash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also flash, telling other drivers
you’re about to
turn, change lanes or stop.
When towing a trailer, the green arrows on your instrument panel
will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
NOTICE:
Do not tow on steep continuous grades exceeding
6 miles (9.6 km). Extended, higher than normal
engine and transaxle temperatures may result
and damage your vehicle. Frequent stops are
very important to allow the engine and transaxle
to cool.
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility
of engine and transaxle overheating.
Pay attention to the engine coolant gage. If the indicator
is in the red area, turn
off the air conditioning to reduce
engine load (see “Engine Overheating” in the Index).
4-38

The coalant level should be at or above FULL COLD
m-ark .or slightly higher.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water
pump or somewhere else in
the cooling system.
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause
an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
1 NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans are running.
If the
engine is overheating, both fans should be running.
If
they aren’t, your vehicle needs service.

You can be injured and your vehicle could be
damaged if you
try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “Ehglish” and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or
fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your retailer before adding equipment to the outside of
your vehicle.
Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. At a minimum, it should meet specifications
ASTM
D4814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications .have been
developed by the American Automobile Manufacturers
Association (MA) for better vehicle performance
and engine protection. Gasolines meeting the
AAMA
specification could provide improved driveability and
emission control system protection compared to
other gasolines.
Be sure the posted octane
is at least 87. If the octane is
less than
87, you may get a heavy knocking noise when
you drive.
If it’s bad enough, it can damage your engine.
If you’re using fuel rated at
87 octane or higher and you
hear heavy knocking, your engine needs service. But don’t worry if you hear a
little pinging noise when
you’re accelerating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane fuel to get rid\

of pinging. It’s the heavy’ constant knock that means
you have
a problem.

I

I If your vehicle is certified to meet California Emission
j Standards (indicated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications. If such fuels are not available
' in states adopting California emissions standards, your
1 vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
1 performance may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or your
vehicle may fail a smog-check test. If this occurs, return
to your authorized Oldsmobile retailer for diagnosis to
determine the cause of failure. In the event it is
1 determined that the cause of the condition is the type of
1 fuels used, repairs may not be covered by your warranty,
~ Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not
his fuel
contains MMT. General Motors does not recommend the
~ use of such gasolines. If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
, malfunction indicator lamp on your instrument panel i may turn on. If this occurs, return to your authorized
i Oldsmobile retailer for service, To
provide cleaner
air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forrning
in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the
air. General Motors recommends that you
use these gasolines
if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don't use it. It can corrode
metal parts in'your fuel system and also damage
plastic and rubber parts. That damage wouldn't
be covered under your warranty.

Checking Things Under the Hood
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on
hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or others
could be burned. Be careful not
to drop or spill
things that will burn onto a hot engine.
Hood Release
The following sections tell you how to check fluids,
lubricants
and important parts under the hood.
To
open the hood, first pull
the
HOOD release handle
inside the vehicle.

Engine Oil
CHECK
OIL
If the CHECK OIL light
on the instrument panel
comes on, it means you
need to check your engine
oil level right away.
For more information, see “Check Oil Light” in the
Index.
You should check your engine oil level regularly;
this is an added reminder.
It’s a good idea to check your engine
oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground. The engine
yellow and
fi-ont
of the oil
dipstick is
located on the engine.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.
