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 hclps to identify the message which is
only displayed in English.
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. If you do not want this
message
to appear, you can cancel it 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 have this message displayed
again.
A/C OVERHEATED - A/C COMPRESSOR OFF - 15
If the refrigerant system ever rcaches 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 - 07
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 - OS
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 Driver
information Center by toggling the INFORMATION button. The normal
range is 1 1.5
to 15.5 volts when the engine is running.

Downloaded from www.Manualslib.com manuals search engine LOW OIL LEVEL - 36
For correct operation of the low oil sensing system, the vehicle should be
on a level surface. A false LOW 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 LOW
OIL LEVEL message appears, and your vehicle has been parked on level
ground with
the engine off for at least 30 minutes, your oil level should be
checked by observing the oil dipstick. Prior to checking your oil level be
sure your engine has
been off for five minutes and your vehicle is on a
level surface. Then check your dipstick and add oil if necessary. See
“Engine
Oil” in the Index.
CHECK WASHER FLUID - 25
This message will appear for a few seconds indicating that you need
washer solvent.
CHANGE OIL SOON - 40
This message will appear when you have used 90% of the engine oil’s
expected life, based on your driving patterns.
CHANGE ENGINE OIL - 82
This means that the life of your engine oil has expired and it should be
changed within 200 miles. See “Engine Oil” and “Filter
Recommendations”
in the Maintenance Schedule. After an oil change the
Oil Life Index must be resct. See “Oil Life Indicator” in the Index on how
to reset it.
CRUISE ENGAGED - 43
This message will appear for a few seconds when you select a speed at
which to cruise.
ENGINE COOLANT HOT - 44
This message will appear when your engine coolant temperature is over
248’ F (126’ C). To avoid added strain on a hot cngine turn off your
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 your
engine and have it serviced before driving
it again. Severe engine damage
can result from an overheated engine. See “Engine Overheating” in the
Index.

Downloaded from www.Manualslib.com manuals search engine ENGINE HOT - A/C COMPRESSOR OFF - 16
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. If 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 - 11

i
This message serves as a warning that the fuel level in your tam IS
critically low. It means you should stop for fuel immediately.
SERVICE A/C SYSTEM A/C COMPRESSOR OFF - 14

and heating system are no longer working. Have your Climate Control
system serviced
if you notice a drop in heating and A/C efficiency.

This message will a ear when the Personalized Automotive Security
System (PASS-Key 11) senses
that an improper ignition key is being used
to
try to start the vehicle. Check the ignition key for damage. If it is
damaged, it may need to be replaced. If you see no damage, clean the
pellet contacts
with a soft cloth or napkin. Remove the ignition key and
wait for the Driver Information Center to display WAIT
3 MINUTES.
The instrument panel cluster
will then run a timer and change the

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 and enhanced vehicle stability.

u 1:
Your vehicle has strategically placed electronic sensors that feed
information
to the vehicle's computer systems. Your vehicle can control
thc ventilation, heating and air conditioning automatically year round.
The outside tcmperature, inside temperature setting, fan speeds and the
ECC selection are displayed on a digital screen.
When the
OFF button is selected, nothing is on, but air will still 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.
The
OUTSIDE temperature is always displayed when your vehicle is
running. You can change it from Celsius to Fahrenheit by pressing the
ENGIMET (English/Metric) button.

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 turned on, in either the AUTO or
ECON setting, and the fan setting is not on H1, a small amount of air will
flow through the defroster duct while
the system is waiting for the engine
coolant
to warm up enough to provide hcat. 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 airflow
to the windshield to prevent fogging under most normal
conditions.
MANUALLY RECIRCULATE INSIDE AIR
There may be times when you want less air from thc outside. To
recirculate the air from the insidc, in the AUTO setting, just set the
temperature
to 60" F (36" C) and adjust your fan speed.
DEFOG
Press 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 sudden rain or snowy conditions.
