BRAKE VACUUM PROBLEM - 10s: The circuit in
the brake booster vacuum has shorted
or is loose when
this message appears. Your vehicle may lose power
brakes but you will still have the use of manual brakes.
The power brakes will not be affected if the problem is
caused by a failed sensor. Have your vehicle serviced
immediately at your Cadillac dealership.
CHANGE ENGINE OIL - 82: This means that the life
of the engine oil has expired and
it should be changed
within 200 miles. See “Engine Oil” and “Filter
Recommendations”
in the Maintenance Schedule booklet.
After an oil change, the Oil Life Indicator must be reset. See “Oil Life Indicator”
in the Index on how to reset it.

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.

STABILITY ENGAGED - 55: If you have the DeVille
Concours, you may see the STABILITY ENGAGED
message on the Driver Information Center. It means that
an advanced, computer-controlled system has come on
to help your Cadillac continue to go in the direction in
which you’re steering. This stability enhancement
system activates when the computer senses that your
Cadillac is just starting to spin, as it might if you hit a
patch
of ice or other slippery spot on the road. When the
system is on, you may hear a noise or feel a vibration in
the brake pedal. This is normal.
When the STABILITY ENGAGED message is on, you should continue to steer in the direction you want to go.
.
The system is designed to help you in bad weather or
other difficult driving situations by making the most of
whatever road conditions will permit. If the STABILITY
ENGAGED message comes on, you’ll know that something has caused your Cadillac to start to spin,
so you should consider slowing down.

Downloaded from www.Manualslib.com manuals search engine STABILITY REDUCED - 54: If you ever see the
STABILITY REDUCED message, it means there may
be a problem with your stability enhancement system.
If
you see this message, try to reset the system (stop; turn
off the engine; then start the engine again). If the
STABILITY REDUCED message still comes on,
however, it means there is a problem,
so you should see
your Cadillac dealer for service.

a proper service center before turning
off the engine.
TOP SPEED FUEL CUT-OFF - 111: This message
will appear when the PCM senses that the maximum
speed for your Cadillac has been reached. The speed
of your vehicle will decrease several mph as the fuel
supply
is cutoff. This allows your vehicle to stay in a
stable operating range.

Downloaded from www.Manualslib.com manuals search engine TRACTION ENGAGED - 91: When your traction
control system is limiting wheel spin, the TRACTION
ENGAGED message will be displayed. Slippery road
conditions may exist

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.
