You will be fine. We tow with one and have done for the last few months, without problems. We have a 1.9 tdi 7 seater (the 5 and 7 seater have different kerbweights/permissible towing weights etc). The kerbweight for the 7 seater, as per the handbook, is 1614kg, however even with the 5 seater with the 460s MTPLM of 1287 you're well within the 85%.
Good tourqey Tdi engine, the 2.0 would be better but the 1.9 does just fine. Had a smokey clutch a few times when reversing but this was due to me slipping it too much, otherwise it's a very practical and stable towing outfit. We average 30mpg towing a significantly larger outfit than yours.
