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.
SERVICE
ENGINE
SOON
Your Cadillac is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and
is intended to
assure that emissions are at acceptable levels for the
life
of the vehicle, helping to produce a cleaner
environment. (In Canada. OBD I1 is replaced by
Enhanced Diagnostics.) The
SERVICE ENGINE SOON
light conles on and a chime will sound to indicate that
there is
a problem and service is required. Malfunctions
often will be indicated by the system before any
problem
is apparent. This may prevent more serious
damage to your vehicle. This system is also designed
to assist your service technician in correctly
diagnosing any malfunction.

soon as possible. If the brake warning light is on, follow
the directions in that part.
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 (digital clusters
only). A single chime will also sound when this
message is displayed.
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 or rear
doors are 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 kdh).
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

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. Turn the
TEMP/AUTO knob to adjust the
temperature if necessary.
If you choose 60°F ( 1 6"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 airflow 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 comfort 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.

the airflow to the windshield with only a small
amount
to the floor outlets.
3f FAN SPEEDS: Press the button with the fan symbol
on it until AUTO is displayed on the screen. At this
setting. the
Fdn speed is autonratically 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 warrn, the
controller allows the
fan to gradually increase to a higher
speed. This prevznts cold air from blowing into the
passenger compartment.
If you want the blower fdn at a
high speed, press the up arl-ujw button until you see €31 on
the display.
If you want the fan speed to be automatic, but
you
Iike 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

display.
If you want the fan speed to mn lower than the
AUTO setting, press the button until L,O AUTO is shown
on the display.
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 on the
display when the system
is OFF.

Downloaded from www.Manualslib.com manuals search engine If it isn’t, the coolant level should be indicated by a
CHECK COOLANT LEVEL message on the Driver
Information Center.
If it is, you may have a leak in the
radiator hoses, heater hoses, radiator, water
pump or
somewhere else in the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them. If
you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could
lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running. If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

If you haven’t found a problem yet, but the coolant level
isn’t at the proper level
(2.5 inches (6.4 cm) below the
base
of the fill neck), add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL“ coolant at
the coolant surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap,
is cool
before
you do it. (See “Engine Coolant” in the Index for
more information.)
* 0
Steam and scalding liquids from a hot cooling
system
can blow out and burn you badly. They are
under pressure, and if you turn the coolant surge
tank pressure cap
-- even a little -- they can come
out at high
speed. Never turn the cap when the
cooling system, including the coolant surge
tank
pressure cap, is hot. Wait for the cooling system
and coolant surge
tank pressure cap to cool if you
ever have to turn the pressure cap.

4. With the coolant surge tank pressure cap off, start
the engine and let it run
until you can feel the upper
radiator hose getting hot. Watch
out for the
engine fans.
By this time, the coolant level inside the coolant
surge tank may be lower.
If the level is lower, add
more of the proper mix to the coolant surge tank
until the level reaches about 2.5 inches (6.4 cm)
below the
bass of the filler neck.
5. Then replace the pressure cap. Be sure the arrows on
the pressure cap line up like this.
Start the engine
and allow it to warm up. If the CHECK
COOLANT LEVEL message does not appear
on the
Driver Information Center. coolant
is at the proper fill
level.
If a CHECK COOL.ANT LEVEL message does
appear. repeat Steps 1 through 3 or see your dealer.

The surge tank is located next to the engine block on the
passenger’s side
of the engine.
The cooling system
is under a lot of pressure when it
is hot. If the CHECK COOLANT LEVEL message
appears
on the DIC, you will need to add coolant.
engine and radiator are hot can allow steam and
scalding liquids to blow
out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little -- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the FULL COLD mark, which is 2.5 inches (6.4 cm)
below the base
of the fill neck. Use a flashlight as
necessary to see into the tank.
