The Hyundai i30 is equipped with an Electronic Parking Brake (EPB), as shown in the picture below.
It is located below the gear shift and this is how it works:
To release the EPB, push down on the button
Shift the gear downwards to D (Drive) and off you go!
To switch gear to R (Reverse), shift the gear upwards
To engage the EPB, shift the gear to 'P' and pull up the EPB button
For extra assurance, you'll see the same sign lit up on the dashboard too.
