2004 CADILLAC DEVILLE instrument panel

Automatic Operation
AUTO (Automatic):When this button is pressed and
the temperature is set, the system will automatically
control the inside temperature, the air delivery mode and
the fan speed. AUTO will appear on the display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting
between 70°F (21°C) and 80°F (27°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest
temperature setting, the system will remain in
manual mode at that temperature and it will not go
into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, seeSensorslater in this
section.
When your vehicle is rst started, the display will show
the driver’s temperature setting, the fan speed, the
air delivery mode and the outside temperature.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
will show readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between them.

Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments to the temperature, the fan
speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
middle of the instrument panel, near the windshield,
or the system will not work properly.There is also a sensor located behind the front grill.
This sensor reads the outside air temperature and helps
to maintain the temperature inside the vehicle. Any
cover on the front of the vehicle could cause a false
reading in the temperature.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog from
your windshield. Use the oor/defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the defrost mode (FRONT) to remove
fog or frost from the windshield more quickly.
yMODEz:Press this button until the oor/defog
symbol appears on the display.
.(Floor/Defog):This mode directs the air equally
between the windshield and the oor outlets. When you
select this mode, the system turns off recirculation
and runs the air-conditioning compressor unless
the outside temperature is at or below freezing. The
recirculation mode cannot be selected while in the
oor/defog mode.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that may
be on your vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they are working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Follow this manual’s
advice. Waiting to do repairs can be costly – and even
dangerous. So please get to know your warning
lights and gages. They are a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-62for
more information.
Instrument Panel Cluster
The instrument panel cluster is designed to let you
know at a glance how your vehicle is running. You will
know how fast you are going, how much fuel you
are using and many of the other things you will need to
know to drive safely and economically.

Speedometer and Odometer
The speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has
been driven, in either miles (used in the United States)
or kilometers (used in Canada).
You may wonder what happens if a vehicle has to have
a new odometer installed. The new one may read
the correct mileage. This is because your vehicle’s
computer has stored the mileage in memory.
Trip Odometer
The trip odometer can record the number of miles or
kilometers traveled for up to two trips.
The trip odometer button is
located to the left of the
steering wheel on the
instrument panel.
The two trip modes are indicated by Trip A and Trip B.
In order to change from one mode to the other,
press the A/B portion of the TRIP button.
By pressing the bottom of this button, you can tell how
many miles have been recorded on either Trip A or
Trip B since you last set the odometer back to zero.
Press the RESET part of the button until zeros appear
to reset each trip mode.
3-47

If your vehicle is rst sold in the United States, the trip
odometer will return to zero after 999.9 miles
(1 609 km). If your vehicle is rst sold in Canada, the
trip odometer will return to zero after 1,242 miles
(1 999 km). The RESET TRIP A/B button only resets
the trip mode (A or B) that is being displayed. Each trip
mode must be reset individually.
Display Mode
On vehicles equipped with the analog cluster, this
button is located between the trip odometer and
ENG/MET button to the left of the steering wheel on the
instrument panel. Press DSPL MODE to turn the
backlighting and the digital speed image on and off.
On vehicles equipped with the digital cluster, press
DSPL MODE to turn the digital displays other than the
speedometer and gear display on and off.
English/Metric Button
By pressing this button
located to the left of the
steering wheel on the
instrument panel, you can
go back and forth from
English (miles) to
metric (kilometers).
Other readings such as temperature, fuel and trip
odometer also go back and forth between English
and metric.
Vehicle Speed Limiter
This feature prevents your vehicle from exceeding
speeds that the tires are not rated for. When this
happens, the engine’s fuel supply is shut off. When the
vehicle speed slows, the fuel supply will come on again.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG or the air bag symbol. The
system checks the air bag’s electrical system for
malfunctions. The light tells you if there is an electrical
problem. The system check includes the air bag sensors,
the air bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, seeAir Bag Systems on page 1-50.
This light will come on when you start your vehicle, and
it will ash for a few seconds. Then the light should
go out. This means the system is ready.If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should ash for a few
seconds when you turn the ignition key to ON. If the
light does not come on then, have it xed so it will
be ready to warn you if there is a problem. United States
