A few obvious things such as lifting on long descents to charge the hybrid battery without wasting fuel. More direct drive than a Prius because it has a DCT rather than a CVT, so you won't find the engine overtaking the car on ascents. I'd use Super petrol. Change the oil and filter every year or every 10,000 miles whichever comes first. There is a separate 12 volt battery for starting the petrol engine. Hybrid batteries last seemingly for ever - we receive very few complaints of failures.
