Power Lumbar
Your vehicle may have this feature. The driver's and
passenger's seatback lumbar support can be adjusted
by moving a control located on the outboard side of
the seat cushions.
To increase or decrease support, hold the control
forward or rearward. 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.
Heated Seats
If your vehicle is equipped
with heated front seats, the
buttons are located on
the climate control panel.
There is one button for the driver and one for the front
passenger. Each button has three settings, LO, HI
and off. The active setting appears on the climate control
panel display. The LO setting warms the seatback
and cushion until the seat approximates normal body
temperature. The HI setting has a slightly higher
temperature.
To turn on the heated seats, press the button once.
The seat will heat to the HI setting. Press the button
again to switch to the LO setting. Pressing the button a
third time turns the system off.
The heated seats can only be used when the ignition is
turned on. When the vehicle is turned off, the heated
seats automatically turn off. If you wish to have the
heated seats on once the vehicle is restarted, press
the button again.
