Audio System(S); Setting The Time For Radios Without Radio Data Systems (Rds) - Cadillac 2004 DeVille Owner's Manual

The DIC may display a CHANGE ENGINE OIL
message. For more information, see Scheduled
Maintenance on page 6-4. If you see CHANGE ENGINE
OIL, it means the oil life is gone and you should
change the oil right away. The system does not check
how much oil you have, so you will still have to check for
that. To see how, see Engine Oil on page 5-14.
When the oil is changed, you will need to reset the
system. See Engine Oil on page 5-14. Always keep a
written record of the mileage and date when you
changed your oil.

Audio System(s)

Notice: Before you add any sound equipment to
your vehicle – like a tape player, CB radio, mobile
telephone or two-way radio – be sure you can
add what you want. If you can, it's very important to
do it properly. Added sound equipment may
interfere with the operation of your vehicle's engine,
radio or other systems, and even damage them.
Your vehicle's systems may interfere with the
operation of sound equipment that has been added
improperly.
So, before adding sound equipment, check with
your dealer and be sure to check federal rules
covering mobile radio and telephone units.
Your audio system has been designed to operate easily
and to give years of listening pleasure. You will get
the most enjoyment out of it if you acquaint yourself with
it first. Figure out which radio you have in your vehicle,
find out what your audio system can do and how to
operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off. See
"Retained Accessory Power (RAP)" under Ignition
Positions on page 2-26.
