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 engine 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 (Option)
(Canada
Only)
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.
2-17

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
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
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
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 outside temperature, the
kind
of oil you have and some other things. Instead of
trying
to list everything here, we ask that you contact
your Cadillac dealer in the area where you’ll be parking
your vehicle.
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
sold
in Canada will have a number after each message.
This number helps to identify the message which is only
displayed in English.
A/C OFF FOR ENGINE PROTECTION - 16: This
message displays when the engine coolant becomes
hotter than the normal operating temperature. To avoid
added strain on a hot engine, the air conditioning
compressor is automatically turned
off so that air
conditioned air
is not delivered. If the coolant
temperature returns
to normal, you must select AC to
return to a normal
A/C compressor operation. If this
message continues to appear, have the system repaired
as soon as possible to avoid compressor damage.
APPLY BRAKE TO SHIFT - 46: This message will
appear if your vehicle is in PARK (P) for about 15 seconds
and the brake is not pressed
in. Remove the message by
holding the
OFF and the blue (cooler) button on the
Electronic Climate Control panel for about five seconds. Hold
the same two buttons again to redisplay the message.
BATTERY NO CHARGE - 07: This message will
appear
if the battery is not being charged. Have the
electrical system checked by your Cadillac dealership at
your earliest convenience.

Downloaded from www.Manualslib.com manuals search engine CHECK COOLANT LEVEL - 02: This message will
appear when there is a low level
of engine coolant. Have
the cooling system serviced by a Cadillac technician as
soon
as possible.
CHECK FUEL GAGE - 39: This message will appear
when the fuel supply is less than four gallons (15.2
L)
and the display is turned off.
CHECK OIL LEVEL - 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface.
A false CHECK OIL LEVEL message
may appear
if the vehicle is parked on grades. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time, and
the oil level is never sensed while the engine is running.
If the CHECK OIL LEVEL message appears, and your
vehicle has been parked on level ground with the engine
off for at least 30 minutes, the oil level should be
checked
by observing the oil dipstick. Prior to checking
the oil level be sure the engine has been off for five
minutes and your vehicle is on a level surface. Then
check the dipstick and add oil
if necessary. See “Engine
Oil”
in the Index.
CHECK WASHER FLUID - 25: This message will
appear for several seconds indicating that
you need
washer solvent.
CRUISE ENGAGED - 43: This message will appear
for a few seconds
when you select a speed at which
to cruise.
DOOR OPEN - 141: The passenger’s door is open or
ajar when this message appears. The vehicle’s engine
must be running and the transaxle not
in.PARK (P) for
this message to display.
A chime will also sound when
the vehicle’s speed is greater than
5 mph
(8.1 km/h).
DRIVER DOOR OPEN - 140: This message
will display when the vehicle is being shifted out
of
PARK (P) with the engine running to signal that
the driver’s door is open or ajar.
A chime will also
sound when the vehicle’s speed is greater than
5 mph
(8.1 W).
ENGINE COOLANT HOT-IDLE ENGINE - 44:
This message will appear when the engine coolant
temperature
is over 248°F (126°C). To avoid added
strain on a hot engine, turn off the climate control
system. Stop and allow your vehicle to idle until
it cools
down
or the message is removed. If it does not cool
down,
turn off the engine and have it serviced before
driving it again. Severe engine damage can result from
an overheated engine. See “Engine Overheating” in
the Index.

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
outlets for a
few seconds. That is normal. This is to
expel hot air in the air outlets.
As the air is cooled, the
aifflow 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.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started.
As the coolant warms
up, the blower fan speed will gradually increase
and air
will flow from the heater outlets, with some aifflow to
the windshield to prevent fogging under most nonnal
conditions.
If you leave your vehicle, the system will remember the
control setting
the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation, whereas,
DEFROST will change
to
AUTO when the ignition is shut off and then turned
back on.
Manual Operation
RECIRCULATION: Press this button to limit the
amount of fresh air entering your vehicle. This is helpful
when you are trying to cool the air quickly or limit odors
entering your vehicle. In the
AUTO mode, the system
will use recirculation as necessary to cool the air.
Pressing the recirculation button will change the
operation to a manual mode and the air will recirculate
non-stop. Press this button again to
turn off the
recirculation feature.
If you notice
the windows fogging, press the
recirculation button
to exit the recirculation mode.
OFF: Press this button to turn the system off.
Fresh air will continue to flow through the vehicle,
and the system will try
to maintain the previously set
temperature. The outside temperature will show in
the display when the system is off.
@ DE-ICE (Option): Pressing this button helps to
remove ice or frost from the windshield. See "Heated Windshield" later in this section.

Downloaded from www.Manualslib.com manuals search engine DEFOG: Press thl's button to divide the air between the
windshield and
the heater outlets. This is useful when
fog appears on the windshield or side glass due to
sudden rain or snowy conditions. This feature is not
available with the heated windshield option.
AUTO/ECON: Press this button to switch between
AUTO and ECON. The ECON setting attempts to keep
air at a selected temperature, however, it does not
remove humidity from the air. Use this setting in cold
or
cool weather to save fuel. The AUTO setting is used
when it's warm outside and you need
to cool the air in
order to maintain a selected temperature and blower
speed.
FAN SPEEDS: Press the button with the fan
symbol until AUTO is displayed on the screen. At this
setting, the fan speed
is automatically controlled. If it is
cold outside, the blower may not
run in the maximum
high
fan speed right away. The system checks the temperature of the engine
coolant to assure it is warm
enough to provide heat. When
the engine coolant is
wm, the controller allows the fan to gradually increase
to a higher speed. This prevents cold air from blowing
into the passenger compartment.
If you want the blower
fan at a high speed, press the up arrow button until you
see HI
on the display. If you want the fan speed to be
automatic, but
you like the fan speed to be higher than
the
AUTO setting, press the fan symbol button until HI
AUTO
is shown on the display. If you want the blower
fan at a
low speed, press the down mow button until
LO is shown on the display. If you want the fan speed to
run lower than the
AUTO setting, press the button until
AUTO LO is shown on the display.
9 DEFROST: Press this button to quickly remove
fog or frost from the windshield.
This setting sends most
of the airflow to the windshield with only a small
amount to the floor outlets.

Downloaded from www.Manualslib.com manuals search engine Engine Overheating
You will find an ENGINE COOLANT HOT-IDLE
ENGINE message
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
Index.
Overheated Engine Protection Operating
Mode
Y
Should a low coolant condition exist and the message
STOP ENGINE
ENGINE OVERHEATED is displayed,
an overheat protection mode which alternates firing
groups
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.
I NOTICE:
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.

Downloaded from www.Manualslib.com manuals search engine If Steam Is Coming From Your Engine
A CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood.
Stay away
from the engine if you
see or hear steam coming
from
it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there
is no sign of steam or coolant before
opening the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You
or others could be badly burned. Stop your
engine if
it overheats, and get out of the vehicle
until the engine is cool.
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. See “Overheated
Engine Protection Operating Mode” in the Index.
