fuel cap BUICK CENTURY 1993 Owners Manual

Fuel Gage
Your fuel gage tells you about how much fuel you have
left, when the ignition is on. When the indicator nears
“E” (Empty), you still have a little fuel left, but you
should get more
soon.
Here are four things that some owners ask about. None
of these show a problem with your fuel gage and are
normal operating characteristics:
At the service station, the gas pump shuts off before the
gage reads
“F” (Full).
It takes a little more or less fuel to fill up than the gage
indicated. For example, the gage may have indicated the tank was half
full, but it actually took
a little more
or less than half the
tank‘s capacity to fill the tank.
The gage moves a little when you turn a corner, speed
up or brake.
The gage doesn’t go back to “E” when you turn off the
ignition.
Engine Oil Pressure Light
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.
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 it fixed right
away.
The
oil light could also come on in three other situations:
When the ignition is on but the engine is not funning,
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

Your Buick Comfort Control
Syst m -
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.
3f : Selects the force of air you want.
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, but directs it in two\

ways. The cool air
is directed to the upper portion of
your body through the instrument panel
outlets, but
warmed air is directed through the heater ducts and
defroster vents. At times
this temperature difference may
be more apparent than others.
To turn the 5x1 off, move the upper lever to the OF'F position.

Towing a Trailer
A CAUTION:
If you don’t use the correct equipment and
drive properly, you can lose control when you
pull a traller. For example, If the trailer is too
heavy, the brakes may not work well--or wen
at all. Mu and your passengets could be
seriously Injured. Pull a trailer only if you have
followed all the steps in this section.
hicle and result
Your Buick can tow a trailer. 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.
Load-pulling components such as the engine, transaxle,
wheel assemblies, and tires are forced to work harder against the drag of the added weight. The engine is
required to operate at relatively higher speeds and under
greater loads, generating extra heat. What’s more, the
trailer adds considerably
to wind resistance, increasing
the pulling requirements.
All of that means changes in:
Handling
Durability
Fuel economy

Filling Your Tank
1
A CAUTION:
Gasoline vapor is highly flammable. It burns
violently, and that can cause very
bad injuries.
Don’t smoke
if you’re near gasoline or
refueling your vehicle. Keep sparks, flames,
and smoking materials away from gasoline.
The cap is behind a hinged door on the left side of your
vehicle.
To take
off the cap, turn it slowly to the left
(counterclockwise).
If you get gasoline on you and then something
ignites
it, you could be badly burned. Gasoline
can spray out on you if you open the fuel filler
cap too quickly. This spray can happen if your
tank is nearly full, and is more likely
in hot
weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then
unscrew the cap
all the way.
When you put the cap back on, turn it to the right until
you hear a clicking
noise.

/i CAUTION:
Things that burn can get on hot engine parts
and start
a fire. These include liquids like
gasoline, oil, coolant, brake fluid, windshield
washer and other fluids, and plastic or rubber.
You or others could be burned. Be careful not
to drop
or spill things that will burn onto a hot
engine.
Before closing the hood, be sure all the filler caps are on
properly. Then just pull the hood down and close it
firmly.
Engine Oil
I‘
I
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. The
3300 V6 engine oil dipstick is located near the front and
center
of the engine compartment.

The other label is the Certification label, found on the
rear edge
of the driver’s door. It tells you the gross
weight capacity of your vehicle, called the GVWR (Gross
Vehicle Weight Rating).
The GVWR includes the weight of the vehicle, all
occupants, fuel and cargo. Never exceed the GVWR for
your vehicle, or the Gross Axle Weight Rating (GAWR)
for either the front or rear axle.
And, if you do have a heavy load, you should spread it
out.
In the trunk or rear area don’t carry more than 160
pounds (72 kg) for the coupeshedans; 300 pounds (136 kg) for the six-passenger wagon.
If you have the eight-
passenger wagon, no additional cargo
can be carried if
you already have eight people in the vehicle.
A CAUTION:
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWRs.
If you do, parts on your vehicle can brerak, or It
can change the way your vehicle handles.
These could cause you to lose control. Also,
overloading can shorten the life of your
vehicle.
If you put things inside your vehicle-like suitcases,
tools, packages, or anything else-they willgo as hst

the vehicle goes. If you have to stop or turn quickly, or if
there is a crash, they’ll keep
