Have bought my wife a corsa b model automatic as she is having knee surgery soon and wont be able to drive my manual. I have never driven an automatic and there isnt a handbook and I cant find any info on the net about automatic corsa's. There is 2 buttons - one on the top of the gear lever marked (s) which I am told is a sports button and another to the left of the base of the gear lever with like a snowflake on the button. What are these used for and what is the correct way to use them? Any links to driving automatic corsa's would be most helpful - thanks in advance.
