Cadillac 2004 DeVille - Manual (Page 124)

If you use the remote keyless entry transmitter to enter
your vehicle and the remote recall memory feature
is on, automatic seat and mirror movement will occur.
The numbers on the back of the transmitters, 1 and 2,
correspond to the numbers on the buttons on the driver’s
door panel.
When the key is placed in the ignition in OFF and you
have entered the vehicle without using the remote
keyless entry transmitter and the remote recall memory
feature is on, the seat, mirrors and steering wheel
will automatically adjust to the programmed position of
the last driver.
To stop recall movement of the memory feature at any
time, press one of the power seat controls or memory
buttons.
