1994 BUICK CENTURY fuel

I NOTICE:
If you keep driving your vehicle with this light on,
after a while the emission controls won’t work as
well, your fuel economy won’t be as good and your engine may not run as smoothly. This could
lead to costly repairs not covered by your
warranty.
Engine Oil Pressure Light
OIL
If you have a problem with
your oil, this light may stay
on after you start your
engine, or come
on when
you are driving. Stop your
car and shut off
the engine
if this light stays on. This
indicates that oil is not
going through your engine
quickly enough to keep
it
lubricated. The engine
could be low
on oil, or could have some
other oil problem. Have.your vehicle serviced
immediately.
The oil light could also come on in three other
situations:
0
0
0
When the ignition is on but the engine is not running,
the light will come on as a
test to show you it is
working, but
the light will go out when you turn the
ignition to “Start.” If
it doesn’t come on with the
ignition on,
you may have a problem with the fuse or
bulb. Have
it fixed right away.
Sometimes when the engine is idling at a stop, the
light may blink on and
off. This is normal.
If you make a hard stop, the light may come on for
a
moment. This is normal.

Your Buick Comfort Control System
The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also has the flow-through ventilation system described
later in this section.
Lever Controls: The upper lever changes the functions
of your system. The lower lever changes the temperature
of the air coming through the system.
The lever next to the fan symbol selects the force of air
you want.
To turn the fan off, move the upper lever to the OFF
Air Conditioning
The upper lever has three air conditioner settings. On
very hot days, open the windows long enough to let hot
inside air escape. This reduces the amount of work your
air conditioner's compressor will have to do, which
should help fuel economy.
MAX: Provides maximum cooling with the least
amount of work. This setting recirculates much
of the
air inside your vehicle
so it maximizes your air
conditioner's performance and fuel economy.
NORM (Normal): Use for normal cooling on hot days.
This setting cools outside air and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use this on cool, but sunny days.
This setting brings in the outside air, and directs it in
two ways. The cool air is directed to the upper portion
of your body through the instrument panel outlets, and
warmed air is directed through the heater ducts and
defroster vents. At times this temperature difference
may be more apparent than others.
The air conditioner compressor operates in all Air
Conditioning positions, and in Defrost when the outside
temperature is above about 40°F (4.5"C).
position.

Ventilation
For mild outside temperatures, when little heating or
cooling is needed, slide the upper lever
to VENT. Air
flow is through the instrument panel outlets. Rotate the
control next to the outlets to turn on, adjust or
turn off
the air flow. Adjust the lower lever
on the control panel
to the temperature desired.
Heating
When outside temperatures are cold, sliding the upper
lever
to HEATER and the lower lever to HOT will send
heated air through the heater ducts, and some through
the defroster vents. VENT and HEATER are labeled
ECONOMY positions because the air conditioner
compressor doesn't run in these two settings. This
reduces engine load, resulting in improved fuel
economy. If either setting fails to keep you comfortable,
or causes your windows
to fog up, slide the upper lever
to one of the Air Conditioning positions, or to DEF
(Defrost).
Defrosting
The DEF setting directs most of the air through the
defroster vents, and some through the heater ducts.
Defog
To quickly defog the windshield, set the upper lever to
DEF and move the fan switch to HI . Slide the lower
lever to
HOT.
In damp, cool weather (temperatures about 45 "-65"F,
7"- 1 8"C), you can use BI-LEV to defog the side
windows. Set the upper lever to BI-LEV and the fan
switch to
HI. Aim the side vents toward the side
windows. For increased air flow to the side vents, close
the center vents.
Rear Window Defogger (Option)
The rear window defogger
uses a warming grid to
remove fog from the rear
window. In winter, it can
also keep ice from forming
on the rear window.

Here are some things you can check before a trip:
Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
0 Wiper Blades: Are they in good shape?
Fuel. Engine Oil. Other Fluids: Have you checked all
levels?
Lights: Are they all working? Are the lenses clean?
0 Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
0 Weather Forecasts: What’s the weather outlook along
your route? Should you delay your trip a short time
to avoid
a major storm system?
0 Maps: Do you have up-to-date maps?
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? First, be
aware that it can happen.
Then here are some tips:
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.

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.
Run your engine only as long as
you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged.
You will need a well-charged battery to
restart the vehicle, and possibly for signaling later
on
with your headlights. Let the heater run for awhile.

Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you
feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as
you can. To help keep warm, you can get
out
of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.
Towing a Trailer
1 NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by your warranty.
To pull a trailer correctly, follow
the advice in this section, and see your Buick
dealer
for important information about towing a
trailer with your vehicle.
Your car can tow a trailer if it is equipped with either the
2.2L L4 engine or the 3 100 SF1 V6 engine and proper
trailer towing equipment.
To identify what the vehicle
trailering capacity
is for your vehicle, you should read
the information in “Weight
of the Trailer” that appears
later in this section. But trailering is different than just
driving your vehicle by itself. Trailering means changes
in handling, durability, and fuel economy. Successful,
safe trailering takes correct equipment, and it has
to be
used properly.
That’s the reason for this section. In
it are many
time-tested, important trailering tips and safety rules. Many of these are important for your safety and that
of
your passengers. So please read this section carefully
before
you pull a trailer.

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 (oxygenates), 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.
NOTICE:
Fuel that is more than 5% methanol is bad for
your vehicle. 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. And even at
5%
or less, there must be “cosolvents” and
corrosion preventers in this fuel to help avoid
these problems.
