Cadillac 1999 DeVille Owner's Manual page 9

Keep in mind that as your seating position changes, as it
may during long trips, so should the position of your
lumbar support. Adjust the seat as needed.
If you have the optional personalization package, the
power lumbar control can be programmed for memory
recall. For more information, see "Memory and
Personalization Features" in the Index.
Massaging Lumbar (If Equipped)
Push the lumbar control, located on the outboard side of
each front seat, up for half a second to activate the
massage feature. The massage cycle will run
continuously for 10 minutes and can be interrupted by
pushing the lumbar control down briefly. The lumbar
support can be adjusted during the massage cycle by
moving the switch forward to increase support and
rearward to decrease support. The massage cycle will
continue to run even if the ignition is turned to OFF,
unless interrupted.
Memory Seat and Mirrors (If Equipped)
Automatic seat and mirror movement will occur if the
Remote Keyless Entry (RKE) transmitter is used to
enter the vehicle. The number on the back of the
transmitter corresponds to the 1 or 2 seat and
mirror position.
After the unlock button is pressed on the RKE
transmitter (the ignition must be in LOCK) or when the
key is placed in the ignition, the seat and mirrors will
automatically adjust to the appropriate position.
Automatic seat and mirror movement is programmed
through the Driver Information Center (DIC) so that the
driver can select whether or not movement will occur
using the RKE transmitter or by placing the ignition key
in the ignition. For programming information, see
"Memory and Personalization Features" in the Index.
