ENGINE BLOCK HEATER (OPTION)
In very cold weather, 0” F (-1 8 C) or colder, the engine block heater can
help. You’ll get easier starting and better fuel econonly during engine
warm-up.
To use the block heater:

2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 1 10-volt outlet.

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 Cadillac
dealer in the area where you’ll be parking your vehicle. The dealer can
give you the best advice
for that particular area.
DRn’lNG THROUGH DEEP STANDING
WATER
NOTICE:
If you drive too quickly through deep puddles or standing water,
water can come in through your engine’s air intake and badly
damage your engine.
If you can’t avoid deep puddles or standing
water, drive through them very slowly.

come out the A/C outlets
to maintain comfort.
Electronic Climate Control Features
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.
Cold Weather Purge
On cold days when your system is first turned on, at any setting other
than Defroster, DEFOG
or OFF a small amount of air will flow through
the defroster duct preventing your windshield from fogging.
Automatic Defog
When using your wipers or rear window defogger for several minutes, the
system senses that
a humid condition exists. When this happens air flow
will be directed to the windshield and floor ducts to keep your side glass
and windshield clear.
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
(16OC) and adjust your fan speed.
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.

from the wind. This will help keep GO out.
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.

window as necessary.
3. 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
still have the warning, TURN
OFF THE ENGINE AND GET
EVERYONE OUT OF THE VEHICLE until it cools down.
You may decide not to lift the hood but to get service help right away.

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 Recovery Tank
If you haven’t found a problem yet, but the coolant level isn’t at or above
“FULL COLD,” add a 50/50 mixture of clean water (preferably distilled)
and
a proper antifreeze at the coolant recovery tank. (See “Engine
Coolant’’
in the Index for more information about the proper coolant
mix.)
