I have recently purchased a 2016 Auris hybrid in the UK and discovered that if you have your annual service with an authorized Toyota dealer its extends the car warranty to 10 years. Its called Toyota Relax here.
Similarly, if you have an annual hybrid battery check, free with the annual service, it extends the hybrid battery warranty to 15 years. You can have the hybrid batteries tested on their own if you want to carry out the service yourself. It's not that much cheaper than the Intermediate service though!
I don't know if it applies elsewhere in Europe.
