Memory Seat
The memory function can recall preset positions for
the driver's seat cushion and the recliner. The memory
function does not store the lumbar or back
support positions.
To set your memory seat do the following:
1. Adjust the driver's seat to the desired position.
2. Press the SET button and then press the 1 or 2 button
of the memory control within five seconds.
When your vehicle is in PARK (P), press the same
button of the memory control to recall the seat setting.
To do the same thing for a second driver, follow the
preceding steps, but press the other number of the
memory control. The memory feature only works when
the transmission is in PARK (P).
The controls for the
memory seat are located on
the driver's door trim panel.
