2005 CADILLAC DEVILLE battery

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 by your GM dealer 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.
CHANGE ENGINE OIL – 82:This means that the life
of the engine oil has expired. SeeScheduled
Maintenance on page 6-4. After an oil change, the oil
life indicator must be reset. SeeEngine Oil Life System
on page 5-17. SeeEngine Oil on page 5-14andOil
Life Indicator on page 3-79for more information.CHANGE TRANS FLUID – 47:This message will
appear when it is time to change the transaxle uid.
SeeScheduled Maintenance on page 6-4for the proper
uid and change intervals.
After the transaxle uid has been changed, the transaxle
uid change indicator must be reset. See “How to
Reset the Transaxle Fluid Indicator” underAutomatic
Transaxle Fluid on page 5-21.
CHECK BRAKE FLUID – 37:This message will
display if the ignition is in ON to inform the driver that
the brake uid level is low. Have the brake system
serviced by your GM dealer as soon as possible. See
Brake System Warning and Parking Brake Indicator
Light on page 3-47.
CHECK COOLANT LEVEL – 2:This message will
appear when there is a low level of engine coolant.
Have the cooling system serviced by your GM dealer as
soon as possible. SeeEngine Coolant on page 5-24.
CHECK FUEL GAGE – 50:(Analog Cluster) This
message will appear when the fuel supply is less than
5 gallons (18.9 L) and the display is turned off. A single
chime will also sound when this message is displayed.

Radio Personalization with Home
and Away Feature
If your vehicle has this feature, DRIVER 1 (HOME or
AWAY) PRESETS or DRIVER 2 (HOME or AWAY)
PRESETS will appear on the display when the radio is
rst turned on.
This feature allows the driver to return to the last used
audio source: radio, cassette, or CD, using the
remote keyless entry transmitter. This feature can also
store and recall AM and FM presets, volume, tone,
and the last selected radio station. The number on the
back of each transmitter, 1 or 2, corresponds to
driver 1 or 2. If transmitter 1 is used to enter the vehicle,
the last used audio source and/or settings set by
driver 1 will be recalled. If transmitter 2 is used to enter
the vehicle, the last used audio source and/or settings
set by driver 2 will be recalled. The settings can also be
recalled by pressing the memory seat buttons 1 or 2
located on the driver’s door.
Your radio can store home and away presets. Home
and away presets allow you to use one set of preset
radio settings in the area where you live, and another set
when you go out of town. You will not need to
reprogram the presets every time you travel.With the radio off and the time displayed, use fast
forward and reverse to select home or away presets.
To select the away presets, press and hold FF for
ve seconds until you hear a beep. The next time the
radio comes on, the away presets will be active.
To select the home presets, press and hold RW for
ve seconds until you hear a beep. The next time the
radio comes on, the home presets will be active.
When battery power is removed and later applied, you
will not have to reset the home radio presets because
the radio remembers them. However, you will have
to reset the away radio presets.
Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
vehicle’s radio. The feature works automatically by
learning a portion of the Vehicle Identication Number
(VIN). If the radio is moved to a different vehicle, it
will not operate. If the radio is removed from your
vehicle, the original VIN in the radio can be used to
trace the radio back to your vehicle.
With THEFTLOCK
®activated, the radio will not operate
if stolen.

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.
Weather Band
Weather band is restricted to speech and the audio
quality is not as good as with the AM or FM bands.
Depending on location, the radio should receive one or
two channels.
Care of the Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes, or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight, and
extreme heat. If they are not, they may not operate
properly or may cause failure of the tape player.The tape player should be cleaned regularly after every
50 hours of use. The radio may display CLEAN TAPE
to indicate that the tape player has been used for
50 hours without resetting the tape clean timer. If this
message appears on the display, the cassette tape
player needs to be cleaned. It will still play tapes, but it
should be cleaned as soon as possible to prevent
damage to the tapes and player. If there is a reduction
in sound quality, try a known good cassette to see if
the tape or the tape player is at fault. If this other
cassette has no improvement in sound quality, clean the
tape player.
For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealer.

You can run the engine to keep warm, but be careful.
{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.

Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality GM brake
parts. When you replace parts of your braking
system —for example, when your brake linings wear
down and you need new ones put in — be sure you get
new approved replacement parts. If you do not, your
brakes may no longer work properly. For example,
if someone puts in brake linings that are wrong for
your vehicle, the balance between your front and rear
brakes can change — for the worse. The braking
performance you have come to expect can change in
many other ways if someone puts in the wrong
replacement brake parts.
Battery
Your vehicle has a maintenance free battery. When it is
time for a new battery, get one that has the replacement
number shown on the original battery’s label. We
recommend an ACDelco
®replacement battery.
Warning:Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
The battery is located under the rear seat cushion.
To access the battery, seeRear Underseat Fuse Block
on page 5-101. You do not need to access the
battery to jump start your vehicle. SeeJump Starting
on page 5-42.
