is turned off.
Adaptive Cruise Control
If the vehicle has adaptive cruise control, read the
Radio Frequency Statementon page 8‑20before using
this feature.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Adaptive Cruise Control is an enhancement to
traditional cruise control and is not a safety system.
It allows you to keep cruise control engaged in
moderate traffic conditions without having to constantly
be reset. Adaptive Cruise Control uses radar to
detect a vehicle directly ahead in your path, within a
distance of 100 m (328 ft), and operates at speeds
above 48 km/h (30 mph). When it is engaged by
the driver, the system can apply limited braking or
acceleration of the vehicle, automatically, to maintain
a selected following distance to the vehicle ahead.

any of the following:
.The others vehicle's lamp(s) are missing,
damaged, obstructed from view, or otherwise
undetected.
.The other vehicle's lamp(s) are covered with dirt,
snow and/or road spray.
.The other vehicle's lamp(s) cannot be detected
due to dense exhaust, smoke, fog, snow, road
spray, mist, or other airborne obstructions.
.Your vehicle's windshield is dirty, cracked,
or obstructed by something that blocks the
view of the IntelliBeam light sensor.
.Your vehicle's windshield is covered with ice, dirt,
haze, or other obstructions.
.Your vehicle is loaded such that the front end of
the vehicle points upward, causing the IntelliBeam
sensor to aim high and not detect headlamps and
taillamps.
.You are driving on winding or hilly roads.
You might need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.
Disabling and Resetting IntelliBeam at the

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on
all vehicles first sold in Canada.
The DRL system comes on when the following
conditions are met:
.It is still daylight and the ignition is on.
.The automatic lights are enabled.
.The transmission is not in P (Park).
When DRL are on, only the front turn signal lamps will
be on. No other exterior lamps will be on when the DRL
are being used. The instrument panel will not be lit.
When the automatic lights are enabled and it is dark
enough outside, the DRL will turn off and the low-beam
headlamps will turn on. When it is bright enough
outside, the low-beam headlamps will go off, and the
DRL will turn back on. If the vehicle is started in a dark
garage, the automatic headlamp system comes on
immediately. Once the vehicle leaves the garage,
it will take about one minute for the automatic
headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not
be as bright as usual. Make sure the instrument panel
brightness lever is in the full bright position. See
Instrument Panel Brightness on page 4‑35.
To operate the vehicle with the DRL off, turn the exterior
lamp control off and then do one of the following:
.Turn the exterior lamp control to the parking lamp
position.
.Turn the exterior lamp control to the headlamp
position.
.Turn the exterior lamp control from AUTO to off
and back to AUTO.
An AUTOMATIC LIGHTS OFF message will appear on
the DIC, showing that automatic lighting has been
disabled. See DIC Warnings and Messages
on
page 4‑76.
The regular headlamp system should be turned on
when needed.

Twilight Sentinel®
Twilight Sentinel®can turn the lamps on and off for you.
A light sensor on top of the instrument panel makes the
Twilight Sentinel work, so be sure it is not covered.With Twilight Sentinel the following will happen:
.When it is dark enough outside, the front turn
signal lamps (DRL) will go off, and the headlamps
and parking lamps will come on. The other lamps
that come on with headlamps will also come on.
.When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch is
in the off position.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it will take about one minute
for the automatic headlamp system to change to DRL if
it is light outside. During that delay, the instrument panel
cluster might not be as bright as usual. Make sure the
instrument panel brightness control is in full bright
position. See Instrument Panel Brightness
on
page 4‑35for more information.
You can idle the vehicle with the lamps off, even when it
is dark outside. First set the parking brake while the
ignition is in OFF/ACCESSORY. Then start the vehicle.
The lamps will stay off until the parking brake is
released.

Black plate (35,1)Cadillac STS Owner Manual - 2011
Twilight Sentinel also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel has turned on
the lamps when you turn off the ignition, the lamps will
remain on until:
.The exterior lamp switch is moved from off to the
parking lamp position.
.A delay time that you select has elapsed.
See Vehicle Personalization
on page 3‑59to select the
delay time needed. You can also select no delay time.
If the ignition is turned off with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel delay will not occur. The lamps will turn off as
soon as the switch is turned off.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on,
the exterior lamps will turn off about 10 minutes after the
ignition is turned off. This protects against draining the
battery in case you have accidentally left the headlamps
or parking lamps on. The battery saver does not work if
the headlamps are turned on after the ignition is
turned off. If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on.

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 you press the
remote keyless entry transmitter unlock button.
If activated by the transmitter, the lighting will remain
active for about 25 seconds. The entry lighting system
uses the light sensor; 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 will dim
to off if the ignition is on, or immediately deactivate if
the power locks are activated.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when
the key is in the ignition and the headlamps are on.
This feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness
outside and the parking lamps are active, the
instrument panel displays can be adjusted by turning
the instrument panel brightness knob. SeeInstrument
Panel Brightness
on page 4‑35for additional
information.
Reading Lamps
The reading lamps are located on the overhead
console. These lamps come on automatically when any
door is opened.
For manual operation, press the button next to each
lamp to turn it on or 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.
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 and the fan may cut back to a lower

speed. For more battery saving information, see
“Battery Saver Active Message”underDIC Warnings
and Messages on page 4‑76.
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 bring the charge back up.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gauge or a 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 are on, such as: 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 BATTERY VOLTAGE LOW. If this message is
displayed, it is recommended that the driver reduce the
electrical loads as much as possible. See
DIC Warnings
and Messages on page 4‑76.
Inadvertent Power Battery Saver
This feature is designed to protect the vehicle's battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, or the garage door opener. When the
ignition is turned off, the power to these features will
automatically turn off after 10 minutes (three minutes if a
new car has 24 km (15 miles) or less). Power will be
restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy lamp switch
is turned on.
