Hi April, and welcome to the Club.
I found it quite easy, but I had used cruise control in a previous car.
First, you have to be travelling at a reasonable speed -- I only use cruise control on dual carriageways and motorways when you will be over 50 mph
When you have reached a reasonable speed -- 50 mph - press the SET button.
Braking and dropping the speed to a slower speed will automatically cancel. You can the press RESUME when you are over 50 mph.
CANCEL takes off cruise control.
Regards,
Peter.
