If the refrigerant system ever reaches an over-pressure condition, this
message
will appear to tell you that the air conditioning compressor has
been turned
off. Air conditioned air will not be delivered to cool your
vehicle. If the pressure returns
to a normal operating range, you must
select “AUTO”, “DEFOG”
, or Defrost to start the compressor. If this
message continues to appear, have the system repaired as soon as
possible to avoid compressor damage.
BATTERY NO CHARGE
This message will appear if your battery is not being charged. Have your
electrical system checked by
your Cadillac dealership at your earliest
convenience.
BATTERY VOLTS HIGH
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 at your earliest convenience.
You can
reduce the charging overload
by using the accessories. Turn on the lights,
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 Driver Information Center by toggling the “INFORMATION’’
button. When the engine is running, the normal range is
11.5 to 15.5
volts.
BATTERY VOLTS LOW
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 your accessories. You can monitor battery
voltage
on the Driver Information Center by toggling the
“INFORMATION” button. The normal range is 11.5 to 15.5 volts.

This message will appear when your engine coolant temperature is over
126°C
(248’F). To avoid added strain on a hot engine, turn off your
Climate Control system and stop and allow your vehicle to idle until it
cools down or the mcssage is removed. If it does not cool down, turn off
your engine and have it serviccd before driving it again. Severe enginc
damage can result from an overheated engine. See “Engine Overheating”
in the Index.
ENGINE HOT - A/C COMPRESSOR OFF
This message will appear when the Climate Control is in “Auto” or
Defrost and the engine coolant
is hotter than the normal operating
temperature.
To avoid added strain on a hot engine the air conditioning
compressor
is automatically turned off. When that happens, air
conditioned air is not delivered.
Tf the coolant temperature returns to
normal,
you must select “AUTO”, “DEFOG” or Defrost to return to a
normal
A/C compressor operation.
FUEL LEVEL VERY LOW
This message. serves as a warning that the fuel level in your tank is
critically low.
It means you should stop for fuel immediately.
LOW A/C REFRIGERANT - SERVICE A/C SOON
This message will appear when the A/C refrigerant is so low that it no
longer can cool well. This message shows that some of the refrigerant has
leaked out
of the system, and that the A/C needs recharging. If you do
not have it recharged,
the system may not cool at all.
CHECK WASHER FLUID
This message shows that the washer fluid reservoir is nearly empty.
REDUCE ENGINE POWER (Northstar Only)
This message will appear if the engine starts to cut cylinders to reduce
power, If this message is ever displayed have your vehicle serviced as soon
as possible.

Downloaded from www.Manualslib.com manuals search engine TURN SIGNAL ON
This message is a reminder, after driving about a mile that you have your
turn
signal on.
TRUNK OPEN
This message indicates that your trunk is opcn when the Ignition is ON.
VERY LOW REFRIGERANT
This message means that the Air Conditioning system detects a
refrigerant level that is low enough to cause damage to the A/C
compressor.
To avoid damage, the A/C compressor automatically turns
off and the Electronic Climate Control will automatically switch from
“AUTO” to “ECON” and remain there. Have your
A/C system serviced if
this message appears.
Speed Sensitive Steering (SSS)
This system varies the amount of steering effort proportionate to your
vehicle speed. Steering is easier at
a lower speed for increased
maneuverability and parking ease.
As your vehicle speed increases, the
steering effort
is also increased proportionately. At highway speeds the
amount
of steering effort is greatly increased to provide a manual like
steering feel for maximum control
an enhanced vehicle stability.
Road Sensing Suspension (Northstar Only)
The Road Sensing Suspension automatically controls the ride of your
vehicle.
The system controls damping forces in the shock absorbers and
struts in response to various road and driving conditions. The system is
capable
of making these changes within milli-seconds.
The
Road Sensing Suspension controller is a computer used to control
and monitor the system. The computer receives inputs from vertical
acceleration sensors, wheel
to body position sensors, vehicle speed
sensor, lift and dive signals, and determines optimum strut valving or
(suspension stiffness) for your current operating conditions.
The
computer also receives feedback from the various components to
determine proper system operation. If the computer receives an incorrect
feedback from the system, an error code will be
set in memory and a
“SERVICE RIDE CONTROC’ message will display on the Driver

Your vehicle has strategicaly placed clectronic sensors, that feed
information to the vehicle’s computer systems. Your vehicle can control
the ventilation, heating, and air conditioning automatically year round.
The outside temperature, inside temperature setting, fan speeds, and the
ECC selection are displayed on a digital screen.
OFF: Nothing is on, but air will flow through your vehicle if you’re
moving. The system
will try to keep the air at the selected temperature,
but it
might not be able to maintain it if it’s hot, or cold, outside.
“OUTSIDE’’ Temperature: The outside temperature is always displayed
when your vehicle is running. You can change
it from Celsius to
Fahrenheit by pushing the ENG/MET(English/Metric) button.

To select the
temperature
you want,
push
the blue button
for a cooler setting and
the red button for a
warmer setting.
The
temperature setting
will be displayed
on
the digital screen.
I
You can select temperatures from 65 F ( 18 " C) to 85 F (69 " C). And, at
each end,
you may choose 60°F (16" C), for maximum cooling, and 903F
(33"C), for maximum heating.We recommend when first getting familiar
with your vehicle, select
75°F (24°C). You may find that your own
personal comfort requires a slightly higher or lower setting. Once you set
the temperature, the system will automatically maintain the set
temperature.
ECON
With this setting it's all automatic, but the air conditioningcorupressor
does not operate and
it won't remove humidity from the alr. However,
the system will try
to keep the air at the selected temperature. Use this
setting
in cold or cool weather to save fuel.
If it's warm outside and you need to cool the air, use the next choice.
AUTO
With this setting, the air conditioning compressor runs and it's all
automatic. In cold weather when the system senses the need for heat, the
air
flow will be directed out the floor ducts. As the interior temperature
approaches
the desired setting, the blower speed will decrease and the air
flow could be directed through the defroster and floor ducts. To maintain
interior comfort, the air
flow may move to the air outlets and floor ducts

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.
