Hyundai Palisade: Heater / Auto Defogging Actuator
Description and operation
The auto defogging sensor is installed on the front window glass. The sensor
judges and sends signal if moisture occurs to blow out wind for defogging. The
air conditioner control module receives a signal from the sensor and restrains
moisture and eliminates defog by the intake actuator, A/C, auto defogging actuator,
blower motor rpm and mode actuator.

Description
Surround View Monitor (SVM) is the system that allows video monitoring of 360
degrees around the vehicle. The system includes 4 ultra optical camera mounted
around the vehicle (front, both sides, rear).
The video from these cameras are applied with distortion compensation, time
point conversion, and video merging technologies to provide sky-view image of
the vehicle's surrounding area, as well as various other view modes...
The driver can disable the power
window switches on the rear passenger
doors by pressing the power window
lock switch.
When the power window lock switch
is pressed:
The rear passenger control will not
be able to operate the rear passenger
power window
Note that the front passenger control
is still able to operate the front
passenger window, and that the
driver master control can still operate
all the power windows...
