2006 CADILLAC STS engine

You can switch from English to metric units through the
Driver Information Center (DIC). SeeDIC Controls
and Displays on page 3-74.
The air-conditioning system removes moisture from the
air, so you may notice water dripping underneath
your vehicle while idling or after turning off the engine.
This is normal.
Manual Operation
yNz(Mode):Pressing the mode switch and
changing the mode cancels automatic operation and
allows the operator to manually select the air delivery
location. Press AUTO to return to automatic operation.
The outboard air outlets will always receive airow
regardless of the mode selected. SeeOutlet
Adjustment on page 3-54to change this airow
from the outboard outlets.
To change the current mode, select one of the following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode directs approximately half
of the air to the instrument panel outlets, and then
directs most of the remaining air to the oor outlets.
In automatic operation, cooler air is directed to the
upper outlets and warmer air to the oor outlets.
[(Floor):This mode directs most of the air to the
oor outlets with some air directed to the outboard
outlets, and a little air directed to the windshield and
side windows.
The mode switch can also be used to select the defog
mode. Information on defogging and defrosting can
be found later in this section.
yAz(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and allows the operator to manually
select the amount of airow. Press AUTO to return to
automatic operation.
If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-55and
Scheduled Maintenance on page 6-4.
h(Recirculation):This button controls the air source
for the climate control system. If you are in AUTO mode,
pressing this button once will choose recirculation. This
mode keeps outside air from coming in the vehicle and
recirculates the air in the vehicle. It can be used to
prevent outside air and odors from entering your vehicle
or to help cool the air inside your vehicle more quickly.

The air quality sensor will not activate due to organic
odors, like skunk, and may not activate on many
chemical-related odors. If you wish to limit these types of
odors, you may choose to manually select recirculation.
Your vehicle may also be equipped with a charcoal lter
that can limit many odors from being pulled into your
vehicle. This lter, like your engines air cleaner lter, will
need to be changed periodically. SeeScheduled
Maintenance on page 6-4. The air quality sensor system
does not protect against carbon monoxide (CO), which
you cannot see or smell. SeeEngine Exhaust on
page 2-39.

of the air to the windshield, with some air directed to the
side windows and outboard panel outlets. In this mode,
the system will automatically turn off recirculation and run
the air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode.
This mode may also cause the fan speed and air
temperature to increase.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
ignition is in ON or during remote start, if programmed.

9(Off):This is the off position.
Y(Vent):This mode directs all the rear passenger
airow to the outlets in the console. This is the normal
position for cool down conditions.
\(Bi-Level):This mode directs airow to the console
outlets and the oor.
[(Floor):This mode directs all of the airow to the
oor. This is the normal position for warm up conditions.
The amount of airow to the rear passengers is
controlled automatically by the front climate control
system, regardless of optional equipment. Airow to the
rear system will be turned off when defrost is selected
on the front climate control panel to direct air to clear
the windshield.
Vehicles equipped with a rear climate control panel,
also, have heated rear seats. There are two buttons,
each with three indicator lights, located between the
two climate control knobs on the rear climate control
panel, to control the rear heated seats. SeeHeated
Seats on page 1-7for additional information.
Be sure to keep the area under the front seats clear of
any objects so the air in your vehicle can circulate
effectively.
Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment air lter. There are two types of lters
available. There is a standard dust lter that traps small
particles including pollen. There is, also, a dust/odor
lter available that traps dust and pollen and also uses
a charcoal element to help reduce many offensive
odors from entering your vehicle. Like your vehicle’s
engine air cleaner/lter, it will need to be changed
periodically. For information on how often to change the
passenger compartment air lter, seeScheduled
Maintenance on page 6-4.
Notice:Driving without a passenger compartment
air lter in place can cause water and small
particles, like paper and leaves, to be pulled into
your climate control system which may cause
damage to it. Make sure you always replace the old
lter with a new one.
3-55

The access panel for the passenger compartment air
lter is located under the hood near the windshield,
on the passenger’s side of the vehicle. SeeEngine
Compartment Overview on page 5-12for more
information on location. SeeDoing Your Own Service
Work on page 5-4for information on doing your
own service work.
To access the passenger compartment air lter, do the
following:
1. Pull back the rubber hood seal from the edge of the
leaf screen vent cover.
2. Remove the three fasteners that hold the lter
access cover in place and slide the cover off.
3. To access the lter, remove the black plastic water
deector by lifting the outboard edge of the deector
to release the retention tab.4. Lift the inboard edge of the deector to release the
retention tab.
5. Lift and slide the water deector toward the inboard
side and remove it.
6. The top edge of the lter should be visible. Reach
in and lift the lter out, pulling upward and toward
the front of the vehicle.
7. Insert the new air lter by sliding it back into place.
Make sure the arrow on the lter is pointing toward
the passenger compartment.
Reverse steps 1 through 3 to reinstall the water
deector, lter cover and the hood seal.

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’re 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’s 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’re 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 3-73for
more information.
3-57

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
See “MPH (km)” underDIC Controls and Displays
on page 3-74for more information.
The odometer mileage can be checked without the
vehicle running. Your vehicle’s odometer works together
with the driver information center. You can set a Trip A
and a Trip B odometer. See “Trip Information” underDIC
Controls and Displays on page 3-74for more information.
If your vehicle ever needs a new odometer installed, the
new one will be set to the correct mileage total of the
old odometer.
Tachometer
This gage indicates the
engine speed in
revolutions per
minute (rpm).
Safety Belt Reminder Light
When the ignition button is pressed to START, a chime
will be provided for several seconds to remind people
to buckle their safety belts. The driver safety belt
light will also be provided and stay on for several
seconds, then it will ash for several more. You should
buckle your seat belt.
This chime and light will be
repeated if the driver
remains unbuckled and the
vehicle is in motion.
If the driver’s belt is buckled, neither the chime nor the
light will be provided.
3-59

If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there may be
a problem with the lights or the passenger sensing
system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag readiness
light ever come on together, it means that
something may be wrong with the airbag
system. If this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front passenger seat
may not have the protection of the frontal
airbag. SeeAirbag Readiness Light on
page 3-60.
Charging System Light
When you turn the engine
on, this light will come on
briey to show that the
generator and battery
charging systems
are working properly.
If this light stays on, your vehicle needs service. You
should take your vehicle to the dealer at once. To save
your battery until you get there, turn off all accessories.
SeeDIC Controls and Displays on page 3-74for
more information.
