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 engine operates. Before adding electrical
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 (Option)
In very cold weather, 0°F (- 18 O 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.
Page 81 of 354
Downloaded from www.Manualslib.com manuals search engine To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
.3. Plug it into a nonnal, grounded 110-volt AC outlet.
I A CAUTION:
Plugging the cord into an ungrounded outlet
an electrical shock. Also, the wrong
of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
a properly grounded three-prong
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.
4. After you’ve used the coolant heater, be sure to store
the cord as it was before to keep it away
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 outside temperature, the
of oil you have and some other things. Instead of
to list everything here, we ask that you contact
your Cadillac dealer in the area where you’ll be parking
The dealer can give you the best advice for
that particular area.

Driver Information Center Messages
These messages will appear if there is a problem sensed
in one of your vehicle’s systems. Vehicles that are first

hotter than the normal operating temperature. To avoid
added strain on a hot engine, the air conditioning

You will find an ENGINE COOLANT HOT-IDLE
or a STOP ENGINE ENGINE
OVERHEATED message on the DIC. There is also an
engine temperature warning light
on the instrument
panel. See “Engine Temperature Warning Light” in the
Overheated Engine Protection Operating
Should a low coolant condition exist and the message
ENGINE OVERHEATED is displayed,
an overheat protection mode which alternates firing
of four cylinders helps prevent engine damage.
This operating mode
allows your vehicle to be driven
to a safe place in
an emergency; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
After driving in the Overheated Engine
Protection Operating Mode,
to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be
severely degraded. Change the
oil and reset the
oil life indicator. See “Engine Oil, When to
~ Change” in the Index.
