I don't warm mine up for too long. The Canadian Venue uses 0W20 oil so it stays pretty thin and lubes the internals quickly. The little engine takes a long time to warm up. Even when I autostart, it times out and the engine shuts off but it isn't fully warmed up. Cold climate Venues have an electric PTC heater so you get heat into the cabin quickly even though the coolant hasn't had time to warm up. If you don't know it's there the warm air gives a false sense that the engine is warming up quickly even though the temperature gauge hasn't moved.
You can tell if the PTC heater is installed if there is a 50 amp fuse installed for it in the under hood fuse box.
