Description and operation
Knocking is a phenomenon characterized by undesirable vibration and noise that
can cause engine damage. Knock Sensor (KS) is installed on the cylinder block and
senses engine knocking.
When knocking occurs, the vibration from the cylinder block is applied as pressure
to the piezoelectric element, and the sensor produces voltage signal to ECM. On
receipt of this signal, ECM will control the ignition timing by retarding the ignition
timing and then advancing the ignition timing when the knocking disappears. This
sequential control can improve engine power, torque and fuel economy.

Kia Stinger (CK) 2018-2023 Service Manual: Auto defogging system
Auto defogging reduces the probability of fogging up the inside of the windshield
by automatically sensing the moisture of inside the windshield.
The auto defogging system operates when the heater or air conditioning is on.
The auto defogging system does not work if you push the Air intake control button,
Air conditioning button, or Mode selection button with the Auto Defogging system
in operation.
