2003 CADILLAC SEVILLE battery

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, the heated seats may not get as warm
as they usually do and the fan may cut back to a
lower speed. For more battery saving information, see
ªBattery Saver Active Messageº under
DIC Warnings
and Messages on page 3-56.
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, cigarette lighters 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.

Accessory Power Outlets
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.
The accessory power outlets are located at the rear of
the center console and on the lower inboard carpeted
panel on the passenger's side of the vehicle.
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.
The accessory power outlet will only operate when the
ignition is in ACC or ON and for 10 minutes after
turning the ignition OFF. If you would like the accessory
power outlet to operate regardless of ignition position,
and for extended periods of time, see your dealer
for more information.
Notice:When using an accessory power outlet,
maximum electrical load must not exceed amperage
rating. Always turn off any electrical equipment
when not in use. Leaving electrical equipment on for
extended periods will drain your battery.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 plugs.
Notice:Adding some electrical equipment to your
vehicle can damage it or keep other things from
working as they should. This wouldn't be covered by
your warranty. Check with your dealer before
adding electrical equipment, and never use anything
that exceeds the amperage rating.
Follow the proper installation instructions that are
included with any electrical equipment you install.
Notice:Power outlets are designed for accessory
plugs only. Do not hang any type of accessory
or accessory bracket from the plug. Improper use of
the power outlet can cause damage not covered
by your warranty.

Charging System Light
When you turn the key to
ON or START, this light
will come on brie¯y
to show that the generator
and battery charging
systems are working
properly.
If this light stays on, you need service and you should
take your vehicle to the dealer at once. To save
your battery until you get there, turn off all accessories.
Brake System Warning and Parking
Brake Indicator Light
Your vehicle's hydraulic brake system is divided into two
parts. If one part isn't working, the other part can still
work and stop you. For good braking, though, you need
both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on
brie¯y when you turn the
ignition key to ON. If it
doesn't come on
then, have it ®xed so it will
be ready to warn you if
there's a problem.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-4. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, mis®ring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to ®x any
mechanical or electrical problems that may have
developed.
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 in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON or CHECK ENGINE light is on or not
working properly.
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.

DIC Warnings and Messages
These messages will appear if there is a problem
sensed in one of your vehicle's systems. Vehicles that
are ®rst sold in Canada will have a number after
each message. This number helps to identify the
problem. You must then press INFO or INFO RESET to
clear the display screen for further use. However, be
sure to take any message that appears on the display
screen seriously and remember that pressing the
INFO or INFO RESET button will only make the
message disappear, not the problem.
DIC messages can also be displayed in French,
German, Spanish and Japanese. Contact your dealer to
have the language display adjusted for your vehicle.
BATTERY NOT CHARGING ± 7:This message
will appear if the battery is not being charged. Have the
electrical system checked by your dealership at your
earliest convenience.
BATTERY SAVER ACTIVE ± 27:This message is
displayed when the vehicle has detected that the battery
voltage is dropping beyond a reasonable point. The
battery saver system will start reducing certain features
of the vehicle that you may not be able to notice. At
the point that features are disabled, this message
is displayed. It means that the vehicle is trying to save
the charge in the battery. Turn off unnecessary
accessories to allow the battery to recharge.BATTERY VOLTAGE HIGH ± 8:This message shows
that the electrical charging system is overcharging
(more than 16 volts). To avoid being stranded, have the
electrical system checked by your dealership. You

BATTERY VOLTAGE LOW ± 6:This message will
appear when the electrical system is charging less than
10 volts or if the battery has been drained. If this
message appears immediately after starting, it is
possible that the generator can still recharge the battery.
The battery should recharge while driving but may
take a few hours to do so. Consider using an auxiliary
charger (be sure to follow the manufacturer's
instructions) to boost the battery after returning home or
to a ®nal destination. If this message appears while
driving or after starting your vehicle and stays on, have
it checked immediately to determine the cause of
this problem. To help the generator recharge the battery
quickly, you can reduce the load on the electrical
system by turning off the accessories. You can monitor
battery voltage on the DIC by pressing the INFO
button. The normal range is 11.5 to 15.5 volts.
