When I bought my GTi it was the first car I've had with an EPB, the salesman just said use it in the same way as you would a manual one, I always release the parking brake before moving off, I hate the idea of just accelerating away relying on the car to sense this and release the brake, I did it once and horrible noise it made surely couldn't have been good, let alone doing that everyday.
Bit like 'hill hold', another function I've turned off as I can't see the point of it and the fact you pull against the 'on' brake doesn't well with me mechanically.
