Within the Ford Focus 1.6 Zetec (mk2.5) I noticed that you can select ESP manually by going through the menu.
Previously when driving my dads lexus 4x4 I went over a round about a bit too quick, and ESP kicked in and saved me from a little accident
But a little confused about the Focus, if you have to manually select this on, whats the point? Shouldnt this kick in automatically?
Can anyone please advise why I can enable\disable this via menu and in what instances will I need to do so?
