2004 CADILLAC CTS battery

Battery Not Charging
This symbol appears
with the Battery Not
Charging message.
When this message appears on the display, there is a
problem with the generator and battery charging
systems. Have the electrical system checked by your
GM dealer as soon as possible.
Battery Saver Active
This symbol appears
with the Battery Saver
Active message.
This message appears when the system detects that
the battery voltage is dropping beyond a reasonable
level. The battery saver system will start reducing certainfeatures of the vehicle that you may not be able to
notice. At the point that the features are disabled, this
message is displayed. It means that the vehicle is trying
to save the charge in the battery.
Turn off all unnecessary accessories to allow the battery
to recharge.
The normal battery voltage range is 11.5 to 15.5 volts.
You can monitor battery voltage on the DIC by pressing
the INFO button until you nd BATTERY VOLTS
(Base audio system) or by selecting Battery Voltage
from the Vehicle Information menu (Navigation system).
Battery Voltage High
This symbol appears
with the Battery Voltage
High message.
This message indicates that the electrical charging
system is overcharging the battery. When the system
detects that the battery voltage is above approximately
16 volts, this message will be displayed.

To reduce the charging overload, use the vehicle’s
accessories. Turn on the exterior lamps and radio, set
the climate control on AUTO and the fan speed on the
highest setting, and turn the rear window defogger on.
The normal battery voltage range is 11.5 to 15.5 volts
when the engine is running. You can monitor battery
voltage on the DIC by pressing the INFO button until you
nd BATTERY VOLTS (Base audio system) or by
selecting Battery Voltage from the Vehicle Information
menu (Navigation system).
Battery Voltage Low
This symbol appears
with the Battery Voltage
Low message.
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 the
engine, 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 by your
GM dealer 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.
The normal battery voltage range is 11.5 to 15.5 volts.
You can monitor battery voltage on the DIC by pressing
the INFO button until you nd BATTERY VOLTS
(Base audio system) or by selecting Battery Voltage
from the Vehicle Information menu (Navigation system).

Setting Preset Stations
Up to 30 stations (six FM1, six FM2, and six AM,
six XM1 and six XM2 (if equipped)), can be programmed
on the six numbered pushbuttons, by performing the
following steps:
1. Turn the radio on.
2. Press BAND to select FM1, FM2, or AM, or
XM1 or XM2.
3. Tune in the desired station.
4. Press and hold one of the six numbered pushbuttons
for two seconds until you hear a beep. The set preset
station number will appear on the display above the
pushbutton that it is set to. Whenever that numbered
pushbutton is pressed for less than two seconds, the
station that was set will return.
5. Repeat the steps for each pushbutton.
To set the preset stations with an equalization
setting, DSP setting, or a PTY setting, see each
of these features later in this section. When a preset
station is selected, once one of these additional
settings is selected, the preset station will remember
each setting and it will remain active, until the
setting is selected off for that preset station.AUTOSTORE PRESETS:To set the preset stations
automatically, perform the following steps:
1. Turn the radio on.
2. Press BAND to select FM1, FM2, or AM.
3. Press the TUNE/SEL knob to enter the main menu.
4. Turn the TUNE/SEL knob until AUTOSTORE
PRESETS appears on the display.
5. Press the TUNE/SEL knob to select. AUTOSTORE
will appear on the display. The radio will
automatically search the band and select and store
the six radio stations with the strongest signal.
The stations will be stored by signal strength, not
sequential order. The set preset station number will
appear on the display above the pushbutton that
it is set to. Whenever that numbered pushbutton is
pressed for less than two seconds, the station
that was set will return.
6. Press the CLR button to exit the display. To return
to the original display, repeatedly press the CLR
button or wait for the display to time out.
When battery power is removed and later applied,
you will not have to reset your radio presets.

XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast to coast. Just as with FM, tall
buildings or hills can interfere with satellite radio signals,
causing the sound to fade in and out. The radio may
display NO XM SIGNAL to indicate interference.
Cellular Phone Usage
Cellular phone usage may cause interference with your
vehicle’s radio. This interference may occur when
making or receiving phone calls, charging the phone’s
battery, or simply having the phone on. This interference
is an increased level of static while listening to the
radio. If static is received while listening to the radio,
unplug the cellular phone and turn it off.
Care of Your CDs
Handle CDs carefully. Store them in their original cases
or other protective cases and away from direct
sunlight and dust. If the surface of a CD is soiled,
dampen a clean, soft cloth in a mild, neutral detergent
solution and clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling CDs. Pick up CDs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of Your CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the lens of the
CD optics with lubricants internal to the CD mechanism.

{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.
