battery CADILLAC STS 2006 1.G User Guide

With Twilight Sentinel®you will see the following
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 you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take approximately one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure your
instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on page 3-39
for 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/ACC. Then start the vehicle. The lamps
will stay off until you release the parking brake.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, your lamps
will remain on until:
The exterior lamp switch is moved from off to the
parking lamp position, or
a delay time that you select has elapsed.
SeeVehicle Personalization on page 2-53to select the
delay time that you want. You can also select no
delay time.
If you turn off the ignition 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, you should turn on the regular
headlamp system when you need it.
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.
3-38

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. Press it again to turn the lamp 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 3-79.
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.
3-40

Accessory Power Outlet(s)
Your vehicle is equipped with accessory power outlets.
The outlets can be used to plug in electrical equipment
such as a cellular telephone, CB radio, etc.
Your vehicle has one outlet in front of the center
console, one in the center console lid and there may be
an additional outlet in the rear of the center console.
Your vehicle may have a small cap that must be
removed to access the accessory power outlet. If it
does, when not using the outlet be sure to cover it
with the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain accessory power plugs may not be compatible
to the accessory power outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information on
the accessory power outlets.Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating of 20 amperes.
Check with your retailer before adding electrical
equipment.
Follow the proper installation instructions that are
included with any electrical equipment you install.
Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.

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.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the Check
Engine light is on or not working properly.
To perform a Check Engine light bulb check with the
keyless ignition, make sure the transmitter fob is in the
passenger compartment. SeeIgnition Positions on
page 2-24. Press the bottom of the ACC button on
the instrument panel and hold the button down for
ve seconds. The instrument panel, including the Check
Engine light, will light up and the ignition will be on, but
the engine will not start — if you press the bottom of the
ACC button only briey, less than ve seconds, the
accessory power mode will be turned on, but not the
ignition. After the bulb check, be sure to press and
release the ACC button again to turn the ignition off
and avoid draining the vehicle’s battery.
Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system.The vehicle would be considered not ready for inspection.
This can happen if you have recently replaced your
battery or if your battery has run down. The diagnostic
system is designed to evaluate critical emission control
systems during normal driving. This may take several
days of routine driving. If you have done this and your
vehicle still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
