Highway Hypnosis
Is there actually such a condition as “hghway 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:

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.

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.
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.
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.
l 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 hin.
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.
could be something
in your lane, like a stalled car or
an accident.
e 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.
As you go over the top of a hill, be alert. There

Tie a red cloth to your vehicle to alert police that
you’ve been stopped by the
snow.
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.
You can run the engine to keep warm, but be careful.
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.

Making Turns
NOTICE:
Making very sharp turns while trailering could
cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you’re turning with a trailer, make wider turns than
normal.
Do this so your trailer won’t strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra
wiring (included in the optional trailering package).
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 arrow’s on your
instrument panel
will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may thlnk drrvers
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
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 transmission overheating.
If you are towing a trailer and you have a manual
transmission with FIFTH
(5) gear, you may prefer not to
use FIFTH
(5). Just drive in FOURTH (4) (or, as you
need
to, a lower gear).

When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belts, cooling system and brake adjustment. Each of these
is covered in this
manual, and the Index will help you find them quickly.
If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use-a flashlight if
you need more light.
Be sure the battery has enough water.
You don’t
need to add water to the Delco Freedom@ battery
installed in every new
GM vehicle. But if a battery
has filler caps, be sure the right amount of fluid is
there. If it is low, add water to take care of that
first. If you don’t, explosive gas could be present.
Battery fluid contains acid that can burn
you.
Don’t get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
I 5. Check that the jumper cables don’t have loose or
missing insulatiofi. If they do, you could get a shock.
The vehicles could be damaged, too.

Fan or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.

The coolant level should be at or above FULL. 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.
I 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 fan is running. If the engine is
overheating, the
fan should be running. If it isn’t, your
vehicle needs service.

If your vehicle is certified to meet California Emission
Standards (indicated
on the underhood tune-up 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 vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system 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 Geo dealer for diagnosis to determine the
cause
of failure. In the event it is determined that the
cause
of the condition is the type of fuels used, repairs
may not be covered by your warranty.
In Canada, some gasolines contain an octane-enhancing
additive called
MMT. If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp
on your instrument
panel may turn
on. If this happens, return to your
authorized Chevrolet/Geo dealer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits
from
forming 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.
1 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
A CAUTICV: I
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. Don’t reach through the
grille to release the underhood lever.
To open the hood, first pull the release handle inside the
glove box.
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.

Before closing the hood, be sure all the filler
caps are on.
Then lift the hood to relieve pressure on the hood prop.
Remove the hood prop from the slot in the hood and
return the prop
to its retainer. Then let the hood down
and close
it firmly.
Engine Oil
If the engine oil
pressure light on the
instrument panel comes
on, it means
you need
to check
your engine oil level
right away.
For more information,
see “Engine Oil Pressure 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.
Turn off the engine and
give the oil a few minutes
drain back into the oil
pan. If you don’t, the oil
dipstick might not show
the actual level.
