Hi there Red Astra, I have just been online and found that you need to set it to 250Nm, or 185 ft.-lbs.
I did my wifes Peugeot last year, and as my torque wrench didn't go high enough, I nipped it up as tight as the air gun would go, and then rolled down to my local tyre garage and got them to check for me. Luckily I was spot on. Hope this is helpful.
