Power steering reservoir 09 Outback 2.0D SE

My steering has got intermittently heavy, so I thought I'd check the fluid levels. Thing is, I can't for the life of me find the reservoir. All the online videos show it being just behind the air filter box, but I have nothing there. Am I being daft, or do I have electronic steering?

I'd expect to see the reservoir near the offside front strut tower. Left hand side as you view the engine.
