2008 CADILLAC SRX sensor

Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes after the
ignition is turned to LOCK/OFF, if the parking lamps or
headlamps have been left on. This protects against
draining the battery. The battery saver does not work if
the headlamps are turned on after the ignition is turned
to LOCK/OFF.
To keep the lamps on for more than 10 minutes, turn
the lamps back on with the exterior lamp control.
Instrument Panel Brightness
Turn the knob clockwise
or counterclockwise to
brighten or dim the
interior lights.
To turn on the dome lamps, turn the knob completely
clockwise as far as it will go. The dome lamps stay
on until they are turned off.
Entry Lighting
The entry lighting system turns on the reading and dome
lamps and the backlighting to the exterior lamp control,
when a door is opened or if the Remote Keyless Entry
(RKE) transmitter unlock button is pressed. If activated
by the RKE, the lighting stays on for about 25 seconds.
The entry lighting system uses the light sensor on the
instrument panel; so it must be dark outside in order for
the lamps to turn on. The lamps turn off about 25 seconds
after the last door is closed. They dim then turn off if the
ignition key is turned to ON/RUN. They immediately turn
off if the power locks are used.
Parade Dimming
This feature does not let the instrument panel
backlight dim during daylight hours while the key is in
the ignition and the headlamps are on. Parade dimming
automatically works with the light sensor, located on top
of the dashboard. If it is dark enough outside and the
parking lamps are on, the backlight on the instrument
panel can be adjusted by turning the instrument panel
brightness knob clockwise or counterclockwise to
brighten or dim the lighting. SeeInstrument Panel
Brightness on page 3-19.

PASS (Passenger’s Climate Control):Press this
button to turn the passenger’s climate control system on
or off. Then press the up or down buttons to choose the
desired setting. Pressing the button again automatically
sets the passengers temperature to the drivers setting.
Turning the passenger’s temperature display off does not
turn off the climate control system for the passenger.
Recirculation Operation
There are three options for bringing air into the
climate control system. They are controlled by
pressing the center button on the climate control panel.
The climate control display indicates one of the following
three modes:
9(Auto Air Inlet):This mode lets the automatic
climate control system choose the best air inlet position
for cooling or warming the vehicle. To have full automatic
climate control, the fan and mode controls must be set to
the AUTO position. Generally, recirculation will only
automatically be selected on hot days.Your vehicle may have an optional Air Quality Sensor.
To activate the air quality sensor, the auto air inlet setting
must be used. For more information, see Air Quality
Sensor found later in this section.
?(Recirculation):This mode recirculates air inside
the vehicle and keeps outside air from coming into
the vehicle. It can be used to help cool the vehicle more
quickly or to prevent odors from entering the vehicle.
Recirculation is not available in the defrost mode.
It is also cancelled when oor or defog mode is selected.
In some conditions using recirculation for long periods
of time can cause the air inside the vehicle to become
too dry or stuffy. To prevent this from happening,
after the air in the vehicle has cooled, select auto
air inlet or outside air.
:(Outside Air):This mode pulls fresh air from
outside the vehicle. Outside air is always selected
in defrost mode to prevent fogging.
3-25

Air Quality Sensor:Your vehicle may have an air
quality sensor to help limit the climate control system
from pulling in irritating or harmful exhaust fumes from
other vehicles. This sensor, when active, monitors the
air quality in front of your vehicle and switches to air
recirculation when poor quality air is detected outside
your vehicle. The air quality sensor does 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, manually select recirculation.
To activate the air quality sensor, if your vehicle has one,
select the Auto Air Inlet on your climate control display.
The word AUTO is shown in the center of the display
under the outline shape of a vehicle. While the air quality
sensor senses poor quality air, the recirculation graphic
appears above the AUTO symbol.
Under some conditions, the air quality sensor system
does not operate. In cold weather, the system might
not be active (even if AUTO is displayed) because of
concerns of fogging your windows, which may occur by
activating recirculation mode. Also, the air quality sensorsystem does not remain in recirculation mode for
extended periods of time that could cause stuffy or very
dry conditions in the vehicle. Following a poorly running
vehicle for an extended period of time may not keep
recirculation active indenitely.
The air quality sensor system does not protect against
carbon monoxide (CO), which you cannot see or smell.
SeeEngine Exhaust on page 2-39.
Air Conditioning
#
(Air Conditioning):Press this button to turn the
air conditioning on or off, and override the automatic
system. When selecting the AUTO fan or AUTO mode,
the air conditioning compressor comes on automatically,
as necessary.
The air conditioning system removes moisture from the
air, so water might drip underneath the vehicle while
idling or after turning off the engine. This is normal.
3-26

Sensors
There is a solar sensor located on top of the instrument
panel, near the windshield.There is an interior
temperature sensor
located below the climate
control system next to
the steering wheel.
An ambient sensor is located behind the grille in front of
the vehicle.
These sensors help the climate control system
automatically control the temperature setting. The
system can supply cooler air to the side of the vehicle
facing the sun. The recirculation mode will also be used
as needed to maintain cool outlet temperatures.
Do not cover any of the sensors or the climate control
system might not work properly.

Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a chime
will sound for several seconds to remind the front
passenger to buckle their safety belt. This would only
occur if the passenger airbag is enabled. SeePassenger
Sensing System on page 1-65for more information.
The passenger safety belt light will also come on
and stay on for several seconds, then it will ash
for several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither the
chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument panel
cluster, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the airbag sensor, the
pretensioners, the airbag modules, the wiring and
the crash sensing and diagnostic module. For more
information on the airbag system, seeAirbag System
on page 1-55.
This light will come on
when you start your
vehicle, and it will ash for
a few seconds. The light
should go out and the
system is ready.
If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your airbag
system may not work properly. Have your vehicle
serviced right away.
