2007 CADILLAC STS high beam

The high-beam headlamps are manually
turned on or you use the ash-to-pass feature.
SeeHeadlamp High/Low-Beam Changer on
page 183andFlash-to-Pass on page 188.
When either of these conditions occur,
the IntelliBeam™ feature is temporarily
disabled until the high-beam stalk is returned
to the neutral position. If either of these
conditions occur and IntelliBeam™ already
has the high-beam headlamps on, the
IntelliBeam™ feature is disabled and the
IntelliBeam™ light in the mirror turns off.
The exterior lamp control is turned to any
setting except AUTO.
When this occurs, IntelliBeam™ is disabled
until the control is turned back to the
AUTO position and the AUTOMATIC LIGHTS
ON message displays on the DIC.
The IntelliBeam™ system is turned off at the
inside rearview mirror.
The vehicle’s speed drops below
15 mph (24 km/h).IntelliBeam™ may not turn off the high-beams if
the system cannot detect other vehicle’s lamps
because of 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 Rearview Mirror
IntelliBeam™ can be disabled and reset to the
original factory setting by using the controls on the
inside rearview mirror.
AUTO
3(IntelliBeam™ On/Off):To disable the
system, press this button on the inside rearview
mirror. The IntelliBeam™ indicator turns off
and does not come back on until the IntelliBeam™
button is pressed again.
When IntelliBeam™ has turned on the high-beams,
pull or push the high-beam stalk. This disables
IntelliBeam™ and the IntelliBeam™ indicator
on the rearview mirror turns off. To re-enable
IntelliBeam™, press the IntelliBeam™ button on
the mirror.
A different sensitivity setting is available for dealer
diagnostics. This is done by pushing and holding
this button for 20 seconds until the light ashes
three times. If you accidentally activate this, the
vehicle’s setting automatically resets each time the
ignition is turned off and then on again; otherwise,
refer to the text above for resetting the system.
Cleaning the IntelliBeam™ Light Sensor
The light sensor is
located on the inside of
the vehicle at the back of
the rearview mirror.
Clean the light sensor window, periodically, using
glass cleaner on a soft cloth. Gently wipe the
sensor window. Do not spray glass cleaner directly
on the surface of the sensor window.
Wiper Activated Headlamps
This feature activates the headlamps and parking
lamps after the windshield wipers have been in
use for about six seconds. For this feature to work,
automatic lighting must be enabled. See
Headlamps on page 211for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also
turn off if the windshield wiper control is turned off.
215

An AUTOMATIC LIGHTS OFF message will
appear on the DIC, showing that automatic lighting
has been disabled.
As with any vehicle, you should turn on the
regular headlamp system when you need it.
Light Sensor
The light sensor for the DRL is located on top of
the instrument panel. If you cover the sensor, it will
read dark, and the exterior lamps may come on
when you do not need them.
Fog Lamps
Use the fog lamps for better vision in foggy or
misty conditions.
The fog lamp controls are located on the turn
signal/multifunction lever.
-(Fog Lamps):The band with this symbol is
used to turn the fog lamps on and off.
The parking lamps must be on for the fog lamps
to work.
To turn the fog lamps on, turn the fog lamp band
on the lever up to the dot and release it. The
band will return to its original position.
To turn the fog lamps off, turn the fog lamp band
up to the dot and release it. The band will
return to its original position, and the fog lamps
will turn off. If the high-beam headlamps are turned
on, the fog lamps will also turn off. They will turn
back on again when you switch back to low-beam
headlamps.
Some localities have laws that require the
headlamps to be on along with the fog lamps.
217

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 264.
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.
221

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 264.
Inadvertent Power Battery Saver
This feature is designed to protect your 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 15 miles (24 km) 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.

Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high
in your eld of view, it may take you more
time to see things you need to see when it
is dark outside. Be sure to keep the HUD
image dim and placed low in your eld
of view.
If equipped, the Head-Up Display (HUD) allows
you to see some of the driver information that
appears on your instrument panel cluster on the
windshield.
The information may be displayed in English or
metric units and appears as an image focused out
toward the front of your vehicle. To change
from English to metric units, seeDIC Controls and
Displays on page 258.
The HUD consists of the following information:
Speedometer
Turn Signal Indicators
High-Beam Indicator Symbol
Driver Shift Control Transmission Feature,
seeAutomatic Transmission Operation on
page 116
Check Gages Icon
Adaptive Cruise Control Features and
Indicators (If Equipped), seeAdaptive Cruise
Control on page 197

Highbeam On Light
This light comes on
whenever the
high-beam headlamps
are on.
See “Intellibeam™ Intelligent High-Beam
Headlamp Control System” underHeadlamps on
page 211andHeadlamp High/Low-Beam
Changer on page 183for more information.
Fuel Gage
The fuel gage shows
approximately how
much fuel is in the tank.
It works only when
the engine is on.If the fuel supply gets low, the Fuel Level Low
message will appear on the DIC and a single
chime will sound. SeeDIC Warnings and
Messages on page 264for more information.
Here are a few concerns some owners have had
about the fuel gage. All of these situations are
normal and do not indicate that anything is wrong
with the fuel gage:
At the gas station the gas pump shuts off
before the gage reads full.
The gage may change when you turn, stop
quickly or accelerate quickly.
It takes a little more or less fuel to ll the tank
than the gage indicated. For example, the gage
may have indicated that the tank was half full,
but it actually took a little more or less than half
the tank’s capacity to ll the tank.

No one can see as well at night as in the daytime.
But as we get older these differences increase.
A 50-year-old driver may require at least twice as
much light to see the same thing at night as a
20-year-old.
What you do in the daytime can also affect your
night vision. For example, if you spend the
day in bright sunshine you are wise to wear
sunglasses. Your eyes will have less trouble
adjusting to night. But if you are driving, do not
wear sunglasses at night. They may cut down on
glare from headlamps, but they also make a
lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or
even several seconds, for your eyes to re-adjust
to the dark. When you are faced with severe glare,
as from a driver who does not lower the high
beams, or a vehicle with misaimed headlamps,
slow down a little. Avoid staring directly into
the approaching headlamps.Keep the windshield and all the glass on your
vehicle clean — inside and out. Glare at night is
made much worse by dirt on the glass. Even
the inside of the glass can build up a lm caused
by dust. Dirty glass makes lights dazzle and
ash more than clean glass would, making the
pupils of your eyes contract repeatedly.
Remember that the headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as the headlamps should be
checked regularly for proper aim, so should your
eyes be examined regularly. Some drivers suffer
from night blindness — the inability to see in dim
light — and are not even aware of it.
