1. Turn off the engine.
2. Open tl hood and unwrap the electrical’cord.
3. Plug it into a normal, grounded 1 10-volt AC outlet.
A CAUTldN:
I I
1 .gging 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. Before starting the engine, be sure to unplug and 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 ph ged
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.

Warning
Light
This light tells you that your
engine has overheated. You
should stop the car and turn
the engine
off as soon as
possible. A warning chime
should also sound if this
light comes on.
As a check, the light should come on for a few seconds
when you start your engine. In the section “Problems on
the Road,” this manual explains what to do. See “Engine
Overheating” in the Index.
Engine Coolant Temperature Gage
Analog Cluster
This gage shows the
engine coolant
temperature.
If the gage
pointer moves into the red
area, the engine is too hot.
That reading means the same thing as the warning
light
-- the engine coolant has overheated. The section
“Problems on the Road” in this manual explains what to
do. See “Engine Overheating” in the Index.

Downloaded from www.Manualslib.com manuals search engine 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. To remove this
message from the DIC display, hold the
OFF and the
blue (cooler) buttons on the digital cluster climate control panel for about five seconds. On the analog
cluster climate control panel, press the
OFF button (next
to the
MODE button) and the down arrow on the PASS
TEMP button for about five seconds. Hold the same two
buttons to display the message again.
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.
BATTERY VOLTS HIGH - 08: This message shows
that the electrical charging system is overcharging (more
than
16 volts). To avoid being stranded, have the
electrical system checked by your Cadillac dealership.
You can reduce the charging overload by using the
accessories. Turn on the lamps and radio, set the climate
control on
AUTO and the fan speed on HI, and turn the
rear window defogger on. You can monitor battery
voltage on the DIC by pressing the INFORMATION
(INFO) button. The normal range is 11.5 to 15.5 volts
when the engine is running.
BATTERY VOLTS LOW - 06: This message will
appear when the electrical system is charging less than 10 volts or if the battery has been drained.
If this
message appears immediately after starting, it is possible
that the generator can still recharge the battery. The
battery should recharge after driving a few miles and the message should
go out. If this message appears while
driving or after starting your vehicle and stays on, have
it checked immediately to determine the cause
of this
problem.
To help the generator recharge the battery
quickly, you can reduce the load on the electrical system
by turning
off the accessories. You can monitor battery

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 or rear
doors are open
or ajar when this message appears. The
vehicle’s engine must be running and the transaxle not
be 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: The driver’s door is
open or ajar when this message appears. The vehicle’s
engine must be running and the transaxle not be 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).
ENGINE COOLANT HOT-IDLE ENGINE - 44:
This message will appear when the engine coolant
temperature is over 248
“F (1 26 “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,
ENGINE MISFIRE -- EASE OFF GAS
PEDAL
- 114: An engine misfire has occurred. You’ll
need to
ease off the gas pedal.
FUEL LEVEL LOW - 11: This message serves as a
warning that the fuel level in the tank
is critically low.
Stop for fuel soon.
ICE POSSIBLE - 13: This message appears when
the outside air temperature is cold enough to create icy
road conditions.
HEADLAMPS SUGGESTED - 23: If it’s dark enough
outside and the twilight sentinel control is
off, a
HEADLAMPS SUGGESTED message will display on the
DIC. This message infonns the driver that turning on the
exterior lamps is recommended even thought the

Downloaded from www.Manualslib.com manuals search engine To find your comfort zone, start with the 75°F (24°C)
setting and allow about 20 minutes for the system to
regulate. Press the red or blue temperature buttons
to
adjust the temperature if necessary. If you choose 60°F
(16"C), the system will remain at that maximum cooling
setting and will not regulate fan speed. If you choose the
temperature of
90°F (32"C), the system will remain at
that maximum heating setting and will not regulate fan
speed. Choosing either maximum setting will not cause
the system to heat or cool any faster.
With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor
outlets.
As the interior temperature approaches a desired
setting, the blower speed will decrease.
To maintain
interior comfort, the aifflow may move to the instrument
panel air outlets and floor outlets (bi-level mode). On
bright sunny days in cold weather, the airflow may come
out of the air conditioning outlets (AC mode) to
maintain cornfort and prevent stuffiness. 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 from the air outlets. As the air is cooled,
the airflow will move through the air conditioning
outlets. If you start your vehicle with the fan setting on
HI, it will skip the air conditioning 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 airflow to
the windshield to prevent fogging under most
normal 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 automatic operation when the ignition
is shut off and
then turned back on.

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.
DEFOG: Press this 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.
AUTOECON: 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 on it 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
warm, 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
arrow 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.
