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? Erst, 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 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.

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
0 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, 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.

7. Don’t let the other
end touch metal.
Connect
it to the
positive
(+) terminal
of the good battery.
8. Now connect the black
negative
(-) cable to
the good battery’s
negative
(-) terminal.
Don‘t let the other end
touch anything
until the
next step. The other end
of the negative cable
doesn’t go to the dead
battery. It goes to a heavy
unpainted metal part on
the engine of the vehicle
with the dead battery.
9. Attach the cable at
least
18 inches (45 cm)
away from the dead
battery, but not near
engine parts that move.
The electrical
connection is
just
as good there, but
the chance
of sparks
getting back to the
battery
is much less.
10. Now start the vehicle with the good battery and
run the engine for
a while.
11. Try to start the vehicle with the dead battery.
If it won’t start after a few tries, make sure all
connections are good.
If it still won’t start, it
probably needs service.
A CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.

12. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal. Towing Your Vehicle
Try to have a GM retailer or a professional towing
service tow your vehicle. See “Roadside Assistance”
in
the Index.
If your vehicle has been changed since it was factory-new
by adding things like
fog lamps, aero skirting, or special
tires and wheels, these instructions may not be conect.
Before you do anything, turn on the hazard
warning flashers.
When you call, tell the towing service:
That your vehicle has all-wheel drive.
The make, model and year of your vehicle.
Whether you can move the shift lever for the
transmission.
A. Heavy Metal Engine Part
B. Good Battery
C. Dead Battery
If there was an accident, what was damaged.
When the towing service arrives, let the tow operator
know that this manual contains these towing
instructions.
The operator may want to see them.

side when towing a vehicle.
A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause
a collision,
serious personal injury and vehicle damage. The
vehicle should be tightly secured with chains
or
steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components.
When your vehicle is being towed, have
the ignition key
turned
to the OFF position. The steering wheel should
be clamped
in a straight-ahead position with a clamping
device designed for
towing service. Do not use the
vehicle’s steering column lock for this.
The transmission
should
be in NEUTRAL (N). The parking brake should
be released.

If No Steam Is Coming From Your Engine
If YOLI get the overheat warning but see or hear no
steam, the problem may
not be too serious. Sometimes
the engine can get
a little too hot when you:
0 Climb a long hill on a hot, day.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute 01- so:
I. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If;' you're in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (0)
or THIRD (3).
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower
for about
10 minutes. If the warning doesn't come back on,
you can drive normally.
If the warning continues, pull over, stop, and park
your vehicle right away.
If there's still no sign of steam, push the accelerator
until the engine speed is about twice as fast as normal
idle speed. Bring the engine speed back
to normal idle
speed after two or three minutes. Now see
if the warning
stops. But then, if you still have the warning, tLm off
the engine ulld get el)eryolw out of the vehicle until it
cools down.
You may decide not
to lift the hood but to get service
help right away.

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.
The coolant level should be at the ADD mark.
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.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, start the engine again. See
if the fan speed increases when idle speed is doubled by
pushing the accelerator pedal down.
If it doesn’t, your
vehicle needs service.
Turn off the engine.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to get the proper Oldsmobile Service Manual.
It
tells you much more about how to service your- Bravada
than this manual can.
To order the proper service
manual, see “Service and Owner Publications”
in
the Index. Your
vehicle has an air
bag system. Before att.emptin,g to
do your own service work, see “Servicing Your Air
Bag-Equipped Oldsmobile” in the Index.
You should keep
a record with all parts receipts and list
the mileage and the date of any service work you
perform. See “Maintenance Record”
in the Index.
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.
0 Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
0 Be sure to use the proper nuts, bolts and
other fasteners. “English” 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 Oldsmobile
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 Oldsmobile 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
still 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.
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 Oldsmobile retailer 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.
