STARTING DISABLED DUE TO THEFT SYSTEM
REMOVE IGNITION KEY
- 33: This message will
appear 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
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.
STOP ENGINE ENGINE OVERHEATED - 42: This
message will appear when the engine has overheated.
Stop and turn the engine off immediately to avoid severe
engine damage. See “Engine Overheating” in the Index.
STOP ENGINE LOW OIL PRESSURE - 35:
If this message appears while the engine is running, stop
the engine and do not operate it until the cause of low
oil pressure is corrected. Severe damage to the engine
can result.
THEFT SYSTEM PROBLEMKAR MAY NOT
RESTART
- 34: This message means there is a problem
in the Personalized Automotive Security System
(PASS-Key
11). A fault has been detected in the system

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.
TRACTION READY - 91: This message informs the
driver that the traction control system is available. This
occurs when the traction on/off button in the glove box
has been returned to an on position (pressing the button
once turns the traction control system off; pressing the

PCM determines the speed your vehicle is limited to.
Have your Cadillac serviced if this message appears.
VERY LOW REFRIGERANT A/C COMPRESSOR
OFF - 12: This message means that the air conditioning
system detects a refrigerant level that is
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 the A/C
system serviced if this message appears.
Traction Active
When your traction control system is limiting wheel
spin, the TRACTION ACTIVE message will be
displayed. SIippery road conditions may exist
if this
message is displayed,
so adjust your driving
accordingly. This message will stay

limiting wheel spin.
Trip Computer
Road Sensing Suspension
The Road Sensing Suspension (RSS) and the optional
Continuous Variable-Road Sensing Suspension
(CV-RSS) automatically adjust the ride
of your vehicle,
with the CV-RSS having
a wider range of control.
Automatic ride control is achieved through the
RSS
controller, a computer used to control and monitor the
suspension system. The controller receives inputs from
various sensors
to determine the proper system response.
If the controller detects a problem
within the system, the
DIC will display
a SERVICE RIDE CONTROL
message. If this message appears, have your vehicle
serviced at your Cadillac dealership.

The button with the fan symbol adjusts the fan speed.
Press the up arrow to increase fan speed and the down
arrow to decrease fan speed.
Temperature Button
The red and blue temperature buttons adjust the air
temperature coming through the system. Press the blue
button for
a cooler setting or the red button for a warmer
setting. The outside temperature
is always displayed
when your vehicle
is running. You can change it from
Fahrenheit
to Celsius by pressing the ENG/MET
(English/metric) button on the
DIC.
Mode Controls
The AUTO/ECON button automatically controls the
direction of air delivery for air conditioning and non-air
conditioning modes.
Automatic Operation
When the system is set for AUTO, sensors will control
the air delivery mode. Air will come from the
floor,
middle or windshield outlets. The fan speed will vary as
the system maintains the selected temperature setting. Be
careful not
to put anything over the solar sensor
located in the middle of the instrument panel near the
windshield. This sensor is used by the automatic system
to regulate temperature.
To find your comfort zone, start with
75°F (24°C)
setting, 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
(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 this 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 A/C outlets (A/C mode) to maintain
comfort and prevent stuffiness.

1 A CAUTION:
Operating the engine with the air cleaner off can
cause
you or others to be burned. The air cleaner
not
only cleans the air, it stops flames if the
engine backfires.
If it isn’t there, and the engine
backfires,
you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner
off.
I NOTICE: ~
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into
your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
