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.
CHANGE TRANS FLUID - 47: This message will
appear when it is time to replace the transaxle fluid. See
the Maintenance Schedule booklet for the proper fluid
and change intervals.
CJ3ECK BRAKE FLUID LEVEL - 37: This message
will display if the ignition is in the
RUN position to
inform the driver that the brake fluid level is low. Check
the brake reservoir level and add fluid as needed. Have
the brake system serviced by a Cadillac technician as 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.

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.

This section tells you how to make your air system work
for
you. Your Electronic Climate Control (ECC) system
uses ozone-friendly
R- 134a refrigerant.
With the ECC system, you can control the heating,

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.

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.
AC: Press this button to turn the air conditioning on and
off. The system will cool and dehumidify the air inside
the vehicle. In the
AUTO mode, the display will show
that
AC is active, but the air conditioning compressor
only operates when the system determines it is needed.
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.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner
to work its best.
With the digital cluster climate control panel, press the
AUTOECON button to assist in cooling air and in
maintaining proper airflow. Adjust the temperature to a
comfortable setting by pressing the blue button to cool
your vehicle and pressing the red button to
warm your
vehicle. Press the fan button arrows up
or down to adjust
the fan speed.
If you have the analog cluster climate control panel,
press the
AC button or the TEMP/AUTO knob to turn
the system on and then select the proper
MODE to direct
airflow. The system will cool and dehumidify the air
inside the vehicle. Also while in the AUTO mode, the
system will use recirculation as necessary to cool the air.
You may also need to adjust the interior temperature and
the fan speed as needed.
When the
air conditioner is on, you may sometimes notice
slight changes in your vehicle’s engine speed and power.
This is normal because the system is designed to cycle the
compressor
on and off to keep the desired temperature.

Climate Control Personalization
(If Equipped)
With this feature, your vehicle will recall the latest
climate control settings as adjusted the last time your
vehicle was operated. This feature allows two different
drivers to store and recall their own climate control settings. The settings recalled by the climate control
system are determined by which RKE transmitter
(“l”
or “2”) was used to enter the vehicle. The number on the
back of the RKE transmitter corresponds to driver
1 or
to driver
2. After the unlock button is pressed on the
RISE transmitter or the ignition key is placed in the
ignition (the ignition must be turned to LOCK), the climate control settings will automatically adjust to
where they were last set. The settings can also be
changed by briefly pressing the memory seat buttons
1
or 2 located on the driver’s door.

Downloaded from www.Manualslib.com manuals search engine If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard on
mountain roads.
Know how to go down hills. The most important
thing to know is this: let your engine do some
of the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have
poor braking or even none going down a hill.
You could crash. Shift down to let your engine
assist vour brakes on a steep downhill slope. Coasting downhill
in
Ir UTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do
all the work of slowing down. They could get so
hot that they wouldn’t work well. You would then
have poor braking or even none going down
a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the
hill better.
Stay in your own lane when driving on two-lane
roads in hills
or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could be
something
in your lane, like a stalled car or an accident.
You may see highway signs on mountains that warn of
special problems. Examples
are long grades, passing or
no-passing zones, a falling rocks area or winding
roads. Be alert to these and take appropriate action.

Downloaded from www.Manualslib.com manuals search engine Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill.
If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) firmly and apply your parking brakes.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
Shift into a gear; and
0 Be sure the parking brake has released.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on
this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system and brake adjustment.
Each of these is covered in
this manual, and the Index
will help you find them quickly.
If you’re trailering, it’s
a good idea to review these sections before you start
your trip.
Check periodically to see that
all hitch nuts and bolts
are tight.
