driving it again. Severe engine damage can result from
an overheated engine. See ªEngine Overheatingº in
the Index.
ENGINE HOT
- A/C OFF - 16: This message
displays when the engine coolant becomes hotter than
the normal operating temperature. To avoid added strain
on a hot engine, the air conditioning compressor is
automatically turned off so that air conditioned air is not

yellowblue
2-88
STABILITY SYS ENGAGED - 55 : You may see the
STABILITY SYS ENGAGED message on the Driver
Information Center. It means that an advanced,
computer
-controlled system has come on to help your
vehicle continue to go in the direction in which you're
steering. This stability enhancement system activates
when the computer senses that your vehicle 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 SYS 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
SYS ENGAGED message comes on, you'll know that
something has caused your vehicle to start to spin, so
you should consider slowing down.
STARTING DISABLED REMOVE KEY
- 33: This
message will appear when the Personalized Automotive
Security System (PASS

improper ignition key is being used to try to start the
vehicle. Check the ignition key for damage. If it isdamaged, 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 DIC to
display WAIT 3 MINUTES. The instrument panel
cluster will then run a timer and change the messages to
WAIT 2 MINUTES, WAIT 1 MINUTE and then
START CAR. When the START CAR message is
displayed, try again to start the engine.
THEFT SYSTEM PROBLEM/CAR MAY NOT
RESTART
- 34: This message means there is a
problem in the Personalized Automotive Security
System (PASS
-Key
II). A fault has been detected
in the system which means that the PASS
-Key II
system is disabled and is not protecting the vehicle. The
vehicle usually restarts, however, you may want to take
your vehicle to a proper service center before turning off
the engine.
TOP SPEED
- FUEL OFF - 111 : This message will
appear when the PCM senses that the maximum speed
for your vehicle 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.

Manual Operation
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.
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 in the
display when the system is off.
DEFOG: Press this button to divide the air between the
windshield and the heater outlets. This is useful when
fog appears on the windshield or side glass due to
sudden rain or snowy conditions.
AUTO/ECON: Press this button to switch between
AUTO and ECON. The ECON setting attempts to keep air
at a selected temperature, however, it does not remove
humidity from the air. Use this setting in cold or coolweather to save fuel. The AUTO setting is used when
it's warm outside and you need to cool the air in order to
maintain a selected temperature and blower speed.
FAN SPEEDS: Press the button with the fan symbol
on it until AUTO is displayed on the screen. At this
setting, the fan speed is automatically 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 warm, the
controller allows the fan to gradually increase to a higher
speed. This prevents cold air from blowing into the
passenger compartment. If you want the blower fan at a
high speed, press the up arrow button until you see HI on
the display. If you want the fan speed to be automatic, but
you like 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 arrow button until LO is shown on the
display. If you want the fan speed to run lower than the
AUTO setting, press the button until AUTO LO is shown
on the display.
DEFROST: Press this button to quickly remove
fog or frost from the windshield. This setting sends most
of the airflow to the windshield with only a small
amount to the floor outlets.

3-10 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
AUTO/ECON 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 your vehicle has a console climate control panel
(which is standard with the analog cluster), press the AC
button or the TEMP/AUTO knob to turn the system on.
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.
Heating
With the digital cluster climate control panel, press the
AUTO/ECON button to direct airflow and to help save
fuel. Adjust the temperature, if necessary, by pressing
the blue button to decrease temperature and pressing the
red button to increase temperature. Also remember to
adjust the fan speed by pressing the up or down arrow.
If your vehicle has a console climate control panel
(which is standard with the analog cluster), press the
MODE button to select heater. Adjust the interior
temperature to a comfortable level and if the fan speed
needs adjusting, press the up or down arrow.
With each system, outside air will be brought in and sent
through the floor, air conditioning or bi
-level outlets
(depending on the condition). The heater works best if
you keep your windows closed while using it.
Defogging and Defrosting
On cool, humid days, use defog (digital cluster climate
control panel only) to keep the windshield and side
windows clear. Use defrost to remove fog or ice from
the windshield quickly in extremely humid or
cold conditions.

The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh
-- such as after a day's
work
-- don't plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll find experienced and able service experts in
Cadillac dealerships all across North America. They'll
be ready and willing to help if you need it.Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?

Wiper Blades: Are they in good shape?

Fuel, Engine Oil, Other Fluids: Have you checked
all levels?

Lamps: Are they all working? Are the lenses clean?

Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long
-distance driving? Are the tires all inflated to the
recommended pressure?

Weather Forecasts: What's the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?

Maps: Do you have up
-to-date maps?

Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.

4-29
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.
Recreational Vehicle Towing
Your vehicle was not designed to be towed with all four
wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing your vehicle with all four wheels on the
ground will damage drivetrain components.
To tow your vehicle, follow these steps:
1. Put the front wheels on a dolly.
2. Put the vehicle in PARK (P).
3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight
-ahead position
with a clamping device designed for towing.
5. Release the parking brake.

Loading Your Vehicle
Two labels on your vehicle show how much weight it
may properly carry. The Tire
-Loading Information label
found on the driver's door tells you the proper size,
speed rating and recommended inflation pressures for
the tires on your vehicle. It also gives you important
information about the number of people that can be in
your vehicle and the total weight that you can carry.
This weight is called the Vehicle Capacity Weight and
includes the weight of all occupants, cargo and all
options not installed in the factory.
The other label is the Certification label, found on the
rear edge of the driver's door. It tells you the gross
weight capacity of your vehicle, called the Gross
Vehicle Weight Rating (GVWR). The GVWR includes
the weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle or the Gross
Axle Weight Rating (GAWR) for either the front or
rear axle.
If you do have a heavy load, you should spread it out.
Don't carry more than 203 lbs. (92 kg) in the trunk.

Towing a Trailer
CAUTION:
If you don't use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example, if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
You may also damage your vehicle; the resulting
repairs would not be covered by your warranty.
Pull a trailer only if you have followed all the
steps in this section. Ask your dealer for advice
and information about towing a trailer with
your vehicle.
Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify what the
vehicle trailering capacity is for your vehicle, you
should read the information in ªWeight of the Trailerº
that appears later in this section. But trailering is
different than just driving your vehicle by itself.
Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering takes correct
equipment, and it has to be used properly.
That's the reason for this part. In it are many
time
-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers. So please read this section carefully
before you pull a trailer.
Load
-pulling components such as the engine, transaxle,
wheel assemblies and tires are forced to work harder
against the drag of the added weight. The engine is
required to operate at relatively higher speeds and under
greater loads, generating extra heat. What's more, the
trailer adds considerably to wind resistance, increasing
the pulling requirements.
