Hyundai Ioniq: Front Seats / Seatback pocket

Power adjustment

The front seat can be adjusted by using the control switches located on the outside of the seat cushion. Before driving, adjust the seat to the proper position so that you can easily control the steering wheel, foot pedals and controls on the instrument panel...

Rear Seats

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...
