1993 BUICK RIVIERA service

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:
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 frequently
and your instruments from time to time. This can
help you avoid a fixed stare.'
Wear good sunglasses in bright light. Glare can
cause drowsiness. But don't wear sunglasses at
night. They will drastically reduce your overall vision at the very time you need all the seeing power
you have.
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.
As in any driving situation, keep pace with traffic and
allow adequate following distances.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.

drive. Just to be safe, drive slower for about ten minutes.
If the warning doesn't come back on, you can drive
normally.

vehicle right away.
If there's still no

Fuel
Use regular unleaded gasoline rated at 87 octane or
higher: It should meet specifications ASTM D4814 in
the U.S. and CGSB 3.5.92 in Canada. These fuels
should have the proper additives,
so you should not have
to add anything to the fuel.
Use regular unleaded gasoline rated at 87 octane or
higher. It should meet specifications ASTM D4814 in
the U.S. and CGSB 3.5-92 in Canada. These fuels should have the proper additives,
so you should not have
to add anything to the
fuel.
In the U.S. and Canada, it’s easy to be sure you get the
right kind of gasoline (unleaded). You’ll see
“UNLEADED” right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler neck.
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. What about gasoline with blending materials that
contain oxygen, such as MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is no
more than 15% MTBE is fine for your vehicle.
Ethanol
is ethyl or grain alcohol. Properly-blended fuel
that is no more than
10% ethanol is fine for your
vehicle.
Methanol is methyl or wood alcohol.

Gasolines for Cleaner Air
Your use of gasoline with detergent additives will help
prevent deposits from forming in your engine and fuel
system. That helps keep your engine in tune and your
emission control system working properly. It’s good €or
your vehicle, and you’ll be doing your part for cleaner
air.
Many gasolines are now blended with materials called oxygenates. General Motors recommends that you use
gasolines with these blending materials, such as MTBE
and ethanol. By doing
so, you can help clean the air,
especially in those parts
of the country that have high
carbon monoxide levels.
In addition, some gasoline suppliers are now producing
reformulated gasolines. These gasolines are specially
designed to reduce vehicle emissions. General Motors
recommends that you use reformulated gasoline. By
doing
so, you can help clean the air, especially in those
parts of the country that have high Ozone levels.
You should ask your service station operators if their
gasolines contain detergents and oxygenates, and if they
have been reformulated
to reduce vehicle emissions.
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).
