Permanent 4 WD on tarmac?

I have a UK model of the Compass, it has "permanent" 4 wheel drive but I'm not sure of the advantages (if any) or indeed what problems it might cause by running in 4WD all the time. The manual doesn't say not to do it and there aren't any strange noises when driving on dry surfaces, but I wonder what others do or have been advised?

Thanks

4x4

Red Compass - The 4x4 Compass and Patriots have a computer-controlled 'on-demand' four wheel drive. It is normally off and comes on as needed.

There is a long discussion at the following thread (at jeep patriot .com):

Our best description of how the 4WD system works is here:

http://www.jeepforum.com/forum/f98/noobish-question-about-patriot-4wd-system-esp-system-423860/

In regards to your question about running in a constant 4WD mode I can't see where this would be a problem or a benefit on dry pavement. Early reports mentioned that the Euro versions would be programmed differently for the Euro market.

The statements made in the other forum such as: "the 4x4 lock only works to 10-15mph" I have not been able to verify other than as Jeep says the Lock Mode is "to master extra slippery conditions at low speed in deep snow. sand and loose gravel", it does not say that it turns off at higher speeds.
