Hyundai Ioniq: Engine Control System / Accelerator Position Sensor (APS). Description and operation
Accelerator Position Sensor (APS) is installed on the accelerator pedal module and detects the rotation angle of the accelerator pedal. The APS is one of the most important sensors in engine control system, so it consists of the two sensors which adapt individual sensor power and ground line. The second sensor monitors the first sensor and its output voltage is half of the first one. If the ratio of the sensor 1 and 2 is out of the range (approximately 1/2), the diagnostic system judges that it is abnormal.

Folding the rear seat
The rear seatbacks can be folded to facilitate carrying long items or to increase
the luggage capacity of the vehicle.
WARNING
Never allow passengers to sit on top of the folded down seatback while
the vehicle is moving. This is not a proper seating position and no seat belts
are available for use. This could result in serious injury or death in case
of an accident or sudden stop.
Objects carried on the folded down seatback should not extend higher
than the top of the front seatbacks. This could allow cargo to slide forward
and cause injury or damage during sudden stops.
