Pre Safe Functions Disabled

[mbenz76]

Just got a message on the cluster that said "Pre Safe functions limited - check owners manual".

I had been stood outside the car with the door open chatting dor a good 15 minutes. Got in and put the key in and before I turned it the message came up.

It went off as soon as the key was turned and hasn't returned despite me switching off and on a few times. And all pre safe things seem to work with the limited testing I can do without crashing.

Any ideas what it might be? And is it one for the dealer?

Thanks

What does the manual say about the message?

Google 'Pre Safe functions limited' a few threads on other forums about it.

Thanks all. I was in between meetings so posted off my iPhone and didn't have time to Google - typically my manual is at home too

Checked manual and it could be anything from dirty sensors on the bumper or the radar to a faulty system. Interestingly one thing it mentioned as a possible cause was interference from electromagnetic radiation - maybe coincidental but I was parked about 30 foot from a massive TV/Radio/Mobile mast.

I will mention it when next at the dealer just in case there are any faults logged but it all seems to be working at least.
