2007 CADILLAC STS V battery

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.

When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R), if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper
free of mud, dirt, snow, ice and slush. Other
conditions that may affect system performance
include things like the vibrations from a jackhammer
or the compression of air brakes on a very large
truck. If after cleaning the rear bumper and then
driving forward at least 15 mph (25 km/h), the
display continues to ash red, see your dealer.
If a trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your trunk
during your last drive cycle, the light may also
ash red. The light will continue to ash whenever
in REVERSE (R) until your vehicle is driven
forward at least 15 mph (25 km/h) without any
obstructions behind the vehicle.
For cleaning instructions, seeWashing Your
Vehicle on page 480.
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 plugged
in for an extended period of time while the
vehicle is off will drain the battery. Power is
always supplied to the outlets. Always unplug
electrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere rating.

If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 74for more on this,
including important safety information.
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. See
Airbag Readiness Light on page 244.
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 258for more information.

Did you just drive through a deep puddle of water?
If so, your vehicle’s electrical system may be wet.
The condition will usually be corrected when
the electrical system dries out. A few driving trips
should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 365. Poor fuel
quality will cause the 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, misring, 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 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 111. 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.
254

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 the
battery or if the 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 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.
If equipped, this light
tells you if there could be
a problem with your
engine oil pressure.
This light will come on briey when you start your
engine. That is a check to be sure the light
works. If it does not come on, be sure to have it
xed so it will be there to warn you if something
goes wrong.
When the light comes on and stays on, it means
that oil is not owing through your engine properly.
You could be low on oil and you might have
some other system problem.
