Manual Lumbar Heated Seats
The knob that controls this
feature is located on the
outboard sides of the
driver's and front
passenger's seats.
Turn the knob toward the front of the vehicle to increase
lumbar support. Turn the knob toward the rear of the
vehicle to decrease lumbar support.
Your vehicle may have
heated seats. If it does,
the heated seat switches
are located in the
instrument panel
switchbank.
This feature will quickly heat the lower cushions and
lower back of the driver's and front passenger's seat. The
left switch is for the driver's seat and the right switch is for
the front passenger's seat.
Press the top of the switch to turn the heater on. Press
the bottom of the switch to turn the heater off. The
heated seat switch will turn off when the ignition
is turned to OFF and will resume operation when the
ignition is turned to ON, unless the switch is turned off.
