In very cold weather, 0 F (-18 C) or colder, the engine coolant heater
can help. You’ll get easier starting and better fuel economy during engine
warm-up. Usually, the coolant heater should be plugged in a minimum
of
four hours prior to starting your vehicle.
To use the coolant 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.
I NOTICE:
I-
I
After you’ve used the coolant heater, be sure to store the cord as
it was before to keep it away from moving engine parts. If you
don’t, it could be damaged.
How long should you keep the coolant 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.

highway driving may increase the range reading).
If the range display shows
“Lo”, you should stop for fuel as soon as
possible.
Your computer needs enough data for
the “RANGE” reading to work,
however,
so it will read “Lo” for a while when your vehicle is brand new
(under
25 miles). Also, it may show “Lo” for a while if your battery has
been disconnected.

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 turnea on, in either the AUTO’br..
ECON setting and the fan setting
is not on “HI”, a small amount of ah ::.
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 in either “AUTO” or “ECON”
setting, 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.
Fan Speeds
Push the (symbol) button
until “AUTO” is displayed on the screen. At this

controlled automatically.
If it is cold outside, the blower may not run in the maximum high fan
speed right away. The system checksthe temperature
of the coolant to

protection mode which alternates firing groups
of four cylinders helps
prevent engine damage. This operating mode allows your vehicle
