2007 CADILLAC DTS battery

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. Power will be restored for an additional
10 minutes if any door or trunk is opened, or the
courtesy lamp switch is turned on.
Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained, if the interior courtesy
lamps, reading/map lamps, visor vanity lamps
or trunk lamp are accidentally left on. If any
of these lamps are left on, they will automatically
turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until
one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then
on again.
The headlamps will time out after 10 minutes,
if they are manually turned on before the ignition
is off.
Ultrasonic Front and Rear Parking
Assist (UFRPA)
If your vehicle is equipped, the Ultrasonic Front and
Rear Parking Assist (UFRPA) system is designed
to help you park. It operates only at speeds less
than 5 mph (8km/h). UFRPA helps make parking
easier and helps you avoid colliding with objects
such as parked vehicles. The UFRPA system
detects objects that are close to the vehicle which
are at least 10 inches (25.4 cm) off the ground and
below hood or trunk level. The system detects
objects up to 4 feet (1.2 m) in front of the vehicle
and up to 8 feet (2.5 m) behind your vehicle.
UFRPA determines how close these objects are
from your bumpers within this area. Four ultrasonic
sensors on the front and rear bumpers are used to
detect the distance to the object.

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.
If your vehicle has a stationary center console,
the power outlet is located inside the lower storage
area. There are outlets also on the right front
lower part of the driver’s seat and in the lower
storage bin. SeeCenter Console Storage Area
on page 155.
There are two accessory power outlets in the rear
seat area located on the door armrests next to
the ashtrays.
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 can be used at
any time.
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 unplugelectrical equipment when not in use and
do not plug in equipment that exceeds
the maximum 20 ampere 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 dealer/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.

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/retailer
at once. To save the battery until you get there,
turn off all accessories. SeeDIC Controls and
Displays on page 240for more information.
Brake System Warning 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 briey when you turn
the engine on. If it does not come on then, have it
xed so it will be ready to warn you if there is a
problem.

Did you just drive through a deep puddle of
water?
If so, your 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 356. 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, 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 in order
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.
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 dealer can prepare the vehicle for inspection.

BATTERY VOLTAGE
This display shows the current battery voltage.
If the voltage is in the normal range, the value
will display. For example, the display may read
BATTERY VOLTAGE 13.2 VOLTS. If the voltage
is low, the display will show LOW. If the voltage is
high, the display will show HIGH. Your vehicle’s
charging system regulates voltage based on the
state of the battery. The battery voltage may
uctuate when viewing this information on the DIC.
This is normal. SeeCharging System Light on
page 229for more information.
If there is a problem with the battery charging
system, the DIC will display a message. SeeDIC
Warnings and Messages on page 246and
Electric Power Management on page 201for
