Downloaded from www.Manualslib.com manuals search engine Malfunction Indicator Lamp (Service Engine Soon Light)
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 comes 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.
I NOTICE:
~
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine
is not
running. If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least
10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following.
If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you just drive through
a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system dries
out.
A few driving trips should turn the
light off.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index).
Poor fuel quality will cause your
engine not to
run as efficiently as designed. You may
notice
this as stalling after start-up, stalling when you put
the vehicle into gear, misfiring, hesitation on acceleration
or stumbling on acceleration. (These conditions may go
away once the engine is warmed up.)
This will be detected
by the system and cause the light to
turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

Downloaded from www.Manualslib.com manuals search engine Driver Information Center Messages
These messages will appear if there is a problem sensed
in one of your vehicle’s systems. Vehicles that
are first
sold in Canada will have a number after each message.
This number helps to identify the message which is only
displayed
in English.
A/C OFF FOR ENGINE PROTECTION - 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 delivered. If the coolant
temperature returns to normal, you must select AC to
return to a normal A/C compressor operation.
If this
message continues to appear, have the system repaired
as soon as possible to avoid compressor damage.

Downloaded from www.Manualslib.com manuals search engine Driver’s Side 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.
Passenger’s Side Temperature Knob
With this feature, the right front passenger can control
the temperature of air for hisher own zone. The
passenger can select a four degree warmer or cooler
temperature from the driver’s setting.
To turn the system on, press the knob on the passenger’s
side armrest. Rotate the knob clockwise to increase the
temperature and turn counterclockwise to decrease the
temperature. Press the knob again
to turn the system off.
Outside Temperature Display
The outside temperature is always displayed when your
vehicle is running. You can change it from Fahrenheit to
Celsius by pressing
the ENG/MET (Englishlmetric)
button on the Driver Information Center (DIC).
The outside temperature sensor is located near the front
grille. The sensor can be affected by road or engine heat
during idling, slow driving
or when the engine is first
started after a short trip. In order to ensure proper
automatic climate control operation, the outside air temperature
display may not update as quickly as
expected. This is
to allow the air surrounding the outside
temperature sensor
to be as close to the actual outside
conditions as possible. This is determined by how much
time has elapsed since the vehicle has been turned
off
and by vehicle speed.
Mode Controls
The AUTOBCON button automatically controls the
direction of air delivery for air conditioning and non-air
conditioning modes.
Automatic Operation
When the system is set for automatic operation, 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.
