1993 BUICK SKYLARK heater

Driving Through Deep Standing
Water
If you drive too quickly through deep puddles 01
standing water, water can come in through
engine’s air intake and badly damage your
engine.
If you can’t avoid deep puddles or
standing water, drive through them very slowly.
Engine Block Heater (Option)
In very cold weather, O°F (-18 “C) or colder, the engine
block heater can help. You’ll get easier starting and
better fuel economy during engine warm-up.
To use the block heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt outlet.
1 A
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock.
Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt outlet.
If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.

How long should you keep the block heater plugged in?
The answer depends on the weather, the kind of oil you
have, and some other things. Instead
of trying to list
everything here, we ask that you contact a Buick dealer in
the area where you’ll be parking
your vehicle. The dealer
can give you the best advice for that particular area.

BIL (Bi-level) Windshield Defrost
This
setting allows the outside air to flow through your
Buick in two ways. Cooler air is directed to the upper
portion of your body through the vent outlets. Slightly
warmer air
is directed through the heater ducts and
defroster outlets.
Vent
Using vent will allow outside air to flow through the
instrument panel outlets. Set the temperature knob as
desired.
Heater
On days when it’s cold outside, this setting sends heated
air through the heater ducts and
the windshield defroster
outlets. If you have the engine block heater, you can use
it in cold weather (+2OoF/-8 OC or lower) to heat your
vehicle’s passenger area quicker. The engine block
heater warms the engine coolant which
will ultimately
warm the passenger area more efficiently.
( See “Engine
Block Heater” in the Index.)
Blend
This setting divides the air flow equally between the
heater and the defroster outlets. This setting operates the defroster. Most
of the air comes
out near the windshield. Use defrost when you get fog or
ice on the windshield.
Rear Window Defogger (Option)
The lines you see on the
rear window warm
the
glass. Press the button to
start warming your
.window. Pressing the
button again will shut it off.
If you
turn the rear defogger on while driving at or
above
45 mph (72 km/h), it will stay on as long as that
speed is maintained.
You must press the button to shut
it
off.

A CAUTION:
I
An electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don’t
do anything else until it cools down.
The coolant level should be at or above
“FULL COLD.”
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.
A CAUTION:
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
-le engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Nt any leak fixed before you drive the vehicle.
If there seems to be no leak, check to see if the electric
engine fan is running.
If the engine is overheating, the
fan should be running.
If it isn’t, your vehicle needs
service.

0 It’s below freezing outside and most trips are less
than
10 miles (16 km).
0 The engine is at low speed most of the time (as in
door-to-door delivery, or in stop-and-go traffic).
0 You tow a trailer often.
0 Most trips are through dusty places.
If any one
of these is true for your vehicle, then you
need to change your oil and filter every
3,000 miles (5
000 km) or 3 months -- whichever comes first.
If none of them is true, change the oil every 7,500 miles
(12
500 km) or 12 months -- whichever comes first.
Change the filter at the first oil change and at every
other oil change after that.
Engine Block Heater: An engine block heater can be a
big help if you have to park outside in very cold weather, -20
F (-29 C) or colder. If your vehicle has
this option, see “Engine Block Heater.” in the Index.
What to Do with Used Oil:
I sed engine oil contains things that have caused
skin cancer in laboratory animals. Don’t let used
oil stay on your skin for very long. Clean your
skin and nails with soap and water,
or a good
hand cleaner. Wash
or properly throw away
c-othing
or rags containing used engine oil.
Used oil can be a real threat to the environment. Don’t
ever dispose of it by pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If
you have a problem propeily disposing of your used oil,
ask your dealer, a service station or a local recycling center for help.
