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
Eess 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:
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 rearview mirrors and your
instruments frequently.
0 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 an 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.
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.
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. Know how to go uphill. Drive in the highest gear
Stay in your own lane when driving on two-lane
possible.
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 hll, 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.

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
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, use the highest gear possible. If
you cannot maintain posted speeds, driving at a lower
speed may help avoid overheating your engine and
transaxle.
If you have a manual transaxle with fifth gear, it’s better
not
to use fifth gear. Just drive in fourth gear (or, as you
need to, a lower gear).
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a
hill. If something goes wrong, your rig
could
start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual transaxle.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK (P), or REVERSE (R)
for a manual transaxle.
5. Release the regular brakes.

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
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 transaxle fluid (don’t overfill),
engine oil, belt, 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.

5. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock.
The vehicles could be damaged, too.
Before you connect the cables, here are some basic
things you should know. Positive
(+) will go to
positive
(+) and negative (-) will go to negative (-)
or a metal engine part.
Don’t connect (+) to (-) or you’ll get a short that
would damage the battery and maybe other
parts,
too.

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.
How to Add Coolant to the Coolant Surge
Tank
If you haven’t found a problem yet, but the coolant level
isn’t at or above FULL COLD, add a 50/50 mixture of
clean water (preferably distilled) and a proper antifreeze
at the coolant surge
tank, but be sure the cooling system,
including the coolant surge tank pressure cap, is cool
before you do it. (See “Engine Coolant” in the Index for
more information about the proper coolant
mix.)

Fuels in Foreign Countries
If you plan on driving in another country outside the
U.S. or Canada, unleaded fuel may be hard to find. Do
not use leaded gasoline. If you use even one tankful,
your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All
of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number (VIN).

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.
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.

Air Filter Replacement

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil
is changed. Refer to the
Maintenance Schedule to determine when to change
your fluid. See “Scheduled Maintenance Services” in the
Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Pontiac dealer Service
Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts
or exhaust system parts, starting a fire. Be sure to
get an accurate reading if
you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
0 When outside temperatures are above 90°F (32” C).
0 At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.
