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 u 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.
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.

If you change your own oil, be sure you use oil that has
the “Starburst” symbol
on the front of the oil container.
If you have your oil changed for you, be sure the oil put
into your engine
is American Petroleum Institute
certified
for gasoline engines.
You should
also use the proper viscosity oil for your
vehicle, as shown
in the following charts:
3.1L V6 Engine
As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can
use SAE 1OW-30 if it’s going
to be
0 OF (- 18 O C) or above. These numbers on an oil
container show its viscosity,
or thickness. Do not use
other viscosity oils, such
as SAE 20W-50.
RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS

As shown in the chart, SAE 1OW-30 is best for your
vehicle. However, you can use
SAE 5W-30 if it's going
to be colder than
60 OF ( 16 O C) before your next oil
change. When it's very cold, you should use SAE
5W-30. These numbers on an oil container show its
viscosity,
or thickness. Do not use other viscosity oils,
such
as SAE 20W-50.
NOTICE:

KEEP ENGINE OIL
AT THE PROPER
LEVEL AND CHANGE AS
RECOMMENDED
This section covers the maintenance required for your
Oldsmobile.
Your vehicle needs these services to retain its
safety, dependability and emission control performance.

Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle
in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance
or the
removal
of important components can significantly
affect
the quality of the air we breathe. Improper fluid
levels or even the wrong tire inflation can increase the
level of emissions from your vehicle.
To help protect our
environment, and to help keep your vehicle in good
condition, please maintain your vehicle properly.
