Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down. It also tells you about
reclining front seatbacks and head restraints.
Power Seats
Horizontal Control: You can adjust your vehicle's front
seats with the horizontal control located on the outboard
edge of each front seat.
Raise or lower the front of the seat by raising or
lowering the forward edge of the control. Raise or lower
the rear of the seat by raising or lowering the rear edge
of the control.
Move the seat forward or rearward by moving the
whole control toward the front or toward the rear of
the vehicle.
Moving the whole control up or down raises or lowers
the entire seat cushion.

1-3 Power Lumbar Control
You can increase or
decrease lumbar support
in an area of the
lower seatback.
To increase support, press
and hold the front of the
control. To decrease
support, press and hold
the rear of the control.
Let go of the control when the lower seatback reaches
the desired level of support.
You can also reshape the side wing area of the lower
seatback for more lateral support.
To increase support, press and hold the top of the
control. To decrease support, press and hold the bottom
of the control. Let go of the control when the lower
seatback reaches the desired level of support.
Memory Seat
The controls for the
memory seat are located on
the driver's door trim panel.
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 ª1º or ª2º
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 button of
the memory control. The memory feature only works
when the transmission is in PARK (P).
