heater CADILLAC SEVILLE 1994 4.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Your engine is designed to work with the electronics in your
vehicle.
If you add electrical parts or accessories, you could
change the
way the fuel injection system operates. Before
adding electrical equipment, check with your dealer.
If you
don’t, your engine might not perform properly.
If you ever have to have your vehicle towed, see the part of this
Manual that tells how to do it without damaging your vehicle.
See “Towing Your Vehicle” in the Index.
ENGINE COOLANT HEATER (ENGINE
BLOCK HEATER) (CANADA ONLY)
(OPTION)
In very cold weather, 0°F (-18O C) or colder, the engine coolant warmer
can help. You’ll get easier starting and better fuel economy during engine
warm-up. Usually, the coolant warmer should be plugged in a minimum
of four hours prior to starting your vehicle.
To use the coolant warmer:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt outlet.

A/C Purge
If your vehicle is sitting out on a hot day and you have it set on AUTO,
the air will first flow out the floor air ducts for a
few seconds. That is
normal. This is to expel hot air in the air ducts.
As the air is cooled, the
flow
will move through the A/C outlets. If you start your vehicle with the
fan setting on
“HI” it will skip the A/C Purge.
Cold Weather Purge
On cold days when your system is first turned on, in either the AUTO or
ECON setting and the fan setting is not on “HI”, a small amount
of air
will flow through
the defroster duct while the system is waiting for the
engine coolant to warm up enough to provide heat. This prevents your
breath from fogging your windshield.
As the coolant warms up, the
blower fan speed will gradually increase and air will flow from the heater
outlets, with some air bleed to the windshield to prevent fogging under
most normal conditions.
Manually Recirculate Inside Air
There may be times, when you don’t want air from the outside. To
recirculate the air from the inside only,
just set the temperature to 60°F
(16°C) and adjust your fan speed, if the air quantity is too high.
DEFOG
Push this button to divide the air between the windshield and the heater
ducts. This
is useful when fog appears on the windshield or side glass due
to a sudden rain or snowy conditions.

Downloaded from www.Manualslib.com manuals search engine 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.

NOTICE:
If your engine catches fire because you keep driving with no
coolant, your vehicle can be badly damaged. The costly repairs \
would not be covered by
your warranty.
IfNo Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no steam, the problem
may not be too serious. Sometimes the engine can get a little too hot
when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning
with no sign of steam, try this for a
minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan speed and open the
3. Dial temperature control to the highest heat setting and open the
window as necessary.
window, as necessary.
4. Try to keep your engine under load (in a drive gear where the engine
runs slower).
If you no longer have the overheat warning, you can drive. Just
to be safe,
drive slower for about ten minutes.
If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle right
away.
If there’s still no sign of steam, you can idle the engine for two or three
minutes while you’re parked, to see if the warning stops. But then, if you

Engine damage from running your engine without coolant isn’t
covered
by your warranty.
If there seems to be no leak, check to see if the electric engine fans are
running.
If the engine is overheating, both fans should be running. If they
aren’t, your vehicle needs service.
How to Add Coolant to the Coolant Surge Tank
If you haven’t found a problem yet, but the coolant level isn’t visible
inside the surge tank add a
50/50 mixture of clean water (preferably
distilled) and a proper antifreeze at the coolant surge tank, but be sure
the cooling system, including the coolant surge tank pressure cap, is cool
before you do it.
(See “Engine Coolant” in the Index for more
information about the proper coolant mix.)
If it isn’t, you may have a leak in the radiator fiose, heater hoses, radiator, -
water pump or somewhere else in the cooling system. -

Downloaded from www.Manualslib.com manuals search engine Engine Oil Additives
Don’t add anything to your oil. Your Cadillac dealer is ready to advise if
you think something should be added.
When to Change Engine Oil
Your Cadillac has an “Oil Life Indicator.” This feature will let you know
when to change your oil
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change. Under severe
conditions, the indicator may come on before
3,000 miles (5 000 km).
Never drive your vehicle more than 7,500 miles (12 000 km) or 12 months
without an oil change.
The system won’t detect dust in the oil.
So, if you drive in a dusty area, be
sure to change your oil every
3,000 miles (5 000 km) or sooner if the
“Change Oil Soon” light comes on. Remember to reset the Oil Life
Indicator when the oil has been changed. For more information, see “Oil
Life Indicator” in the Index.
How to Reset the Oil Life Indicator
After the oil has been changed, display the “OIL LIFE LEFT” message
by pressing the INFORMATION button. Then press and hold the
RESET button until the display shows “100”. This resets the
oil life index.
The message will remain off until the next oil change
is needed. The
percentage
of oil life remaining may be checked at, any time by pressing
the INFORMATION button several times until the “OIL LIFE LEFT”
message appears. For more information on the Oil Life Index feature,
see
“Oil Life Index” in the Index.
Engine Coolant Heater (Engine Block Heater)
An engine coolant heater can be a big help if you have to park outside in
very cold weather, 0” F (-18OC) or colder. If your vehicle has this option,
see “Engine Coolant Heater” in the Index.

Downloaded from www.Manualslib.com manuals search engine If you use an improper coolant mix, your engine could overheat
and be badly damaged. The repair cost wouldn’t be covered by
your warranty.
Too much water in the mix can freeze and crack
the engine, radiator, heater core and other parts.

Adding Coolant
Your cooling system when hot is under a lot of pressure. If the “ENGINE
COOLANT LOW” message should appear on the Driver Information
Center, you will need to
add coolant.
If the “ENGINE COOLANT LOW” message does not appear, the
coolant is
at the proper fill level.
