edge of the control.
Move the seat forward or rearward by moving the whole
control toward the front or toward the rear of the

the entire seat cushion.
Vertical Control:You can use the vertical control to
adjust the angle of the seatback. Move the reclining

control toward the front or toward the rear of the
vehicle.
For information on the reclining seatbacks, see
Reclining
Seatbacks on page 1-5.
Your vehicle may have a memory function which allows
seat settings to be saved and recalled. See
Memory
Seat on page 2-48for more information.
1-3

Power Lumbar
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.
Your vehicle may have a memory function which allows
seat settings to be saved and recalled. See
Memory
Seat on page 2-48for more information.
Heated Seats
The buttons used to
control this feature are
located on the front doors.
The engine must be
running for the heated seat
feature to work.
To heat the entire seat, press the horizontal button with
the heated seat symbol. Press the button to cycle
through the temperature settings of high, medium and
low and to turn the heated seat off. Indicator lights
will glow to designate the level of heat selected, three
for high, two for medium, and one for low.
The low setting warms the seatback and cushion until
the seat temperature is near body temperature. The
medium and high settings heat the seatback and seat
cushion to a slightly higher temperature. You will be able
to feel heat in about two minutes.
1-4

To heat only the seatback, press the vertical button with
the heated seatback symbol. An indicator light on the
seatback button will glow to designate that only the
seatback is being heated. Additional presses of
the seatback button will cycle through the heat levels for
the seatback only. Press the horizontal button again
to heat the whole seat.
The heated front seats will shut off automatically when
the ignition is turned off.
Reclining Seatbacks
The vertical power seat control described earlier allows
the seatback to recline.
But don't have a seatback reclined if your vehicle is
moving.
{CAUTION:
Sitting in a reclined position when your vehicle
is in motion can be dangerous. Even if you
buckle up, your safety belts can't do their job
when you're reclined like this.
The shoulder belt can't do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt can't do its job either. In a crash
the belt could go up over your abdomen. The
belt forces would be there, not at your pelvic
bones. This could cause serious internal
injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit
well back in the seat and wear your safety belt
properly.
