2007 CADILLAC DTS climate control

Wiper Activated Headlamps
This feature activates the headlamps and parking
lamps after the windshield wipers are turned
on and have completed eight wipe cycles within
four minutes.
When the ignition is turned to OFF, the
wiper-activated headlamps immediately turn off.
The wiper-activated headlamps also turn off if the
windshield wipers are turned off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp
control is left on in either the headlamp or parking
lamp position and the driver’s door is opened
with the ignition off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier
for others to see the front of your vehicle during
the day. DRL can be helpful in many different
driving conditions, but they can be especially
helpful in the short periods after dawn and before
sunset. Fully functional daytime running lamps
are required on all vehicles rst sold in Canada.
The DRL system will make the turn signal lamps
come on when the following conditions are met:
It is still daylight and the ignition is on.
The exterior lamp control is in the off position.
The transaxle is not in PARK (P)
(United States only).
The light sensor is covered or not detecting
light. See “Sensors” underDual Climate Control
System on page 210.
When DRL are on, no other exterior lamps such as
the parking lamps, taillamps, etc. will be on when
the DRL are being used. Your instrument panel will
not be lit up either.

Entry Lighting
This feature turns on the courtesy lamps and the
backlighting to the door switches and to the exterior
lamp control when a door is opened or if you press
the remote keyless entry transmitter unlock button.
If activated due to the transmitter, the lighting will
remain active for about 40 seconds. Since the entry
lighting system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn
on. The courtesy lamps turn off approximately
25 seconds after the last door is closed. They will
dim to off if the ignition key is turned to RUN, or
immediately deactivate if the power locks are
activated.
Parade Dimming
This feature prohibits dimming of the digital
displays and backlighting during daylight hours
when the key is in the ignition and the headlamps
are on. This feature is fully automatic. When
the light sensor reads darkness outside and the
parking lamps are active, the digital displays
can be adjusted by turning the instrument panel
brightness knob counterclockwise to dim and
clockwise to brighten lighting.
Reading Lamps
The reading lamps are located on the overhead
console on the headliner and in the rear door
opening. These lamps come on automatically
when any door is opened and it is dark outside.
For manual operation, press the button to
turn them on. Press it again to turn them off.
If the reading lamps are left on, they automatically
shut off 10 minutes after the ignition has been
turned off.
Battery Load Management
The battery load management feature is
designed to monitor the vehicle’s electrical
load and determine when the battery is in a
heavy discharge condition. During times of high
electrical loading, the engine may idle at a higher
revolutions per minute (rpm) setting than normal
to make sure the battery charges. High electrical
loads may occur when several of the following are
on: headlamps, high beams, fog lamps, rear
window defogger, the climate control fan at high
speeds, heated seats and engine cooling fans.
200

If the battery continues to discharge, even with
the engine idling at a higher rpm setting, some
electrical loads will automatically be reduced. When
this occurs, the rear window defogger may take
slightly longer to clear the glass, the heated seats
may not get as warm as they usually do and the
climate control fan may cut back to a lower speed.
For more battery saving information, see “Battery
Saver Active Message” underDIC Warnings and
Messages on page 246.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature
and state of charge. It then adjusts the voltage for
best performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC),
you may see the voltage move up or down.
This is normal. If there is a problem, an alert
will be displayed.The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to produce
all the power that is needed for very high electrical
loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans,
trailer loads, and loads plugged into accessory
power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s
output and the vehicle’s electrical needs. It can
increase engine idle speed to generate more
power, whenever needed. It can temporarily
reduce the power demands of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action
may be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or Service
Battery Charging System. If this message is
displayed, it is recommended that the driver reduce
the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 246.

Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, and ventilation for the vehicle.
To avoid window fogging on rainy and humid
days at temperatures above freezing, run the
air conditioning compressor. Also, it is best
to avoid the use of recirculation mode except
when maximum air conditioning performance
is needed for a short amount of time to avoid
exterior odors and fogging.

Automatic Operation
AUTO9(Automatic Fan):When this position
is selected on the fan control, the system will
adjust the fan speed. If the OnStar
®system
is activated when this position is selected,
the climate control fan speed will lower.AUTO (Automatic Mode):
1. Turn the fan control to the AUTO position.
2. Turn the mode control to the AUTO position.
3. Adjust the temperature to a comfortable
setting between 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. 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
to warm the interior will depend on the outside
temperature and temperature of the vehicle.
4. Wait 20 to 30 minutes for the system to
stabilize in order for the system to regulate
automatically. Then adjust the temperature
as necessary to nd your comfort setting.
Do not cover the solar sensor located in the
center of the instrument panel near the windshield.
