Okay, I've been a good member by searching the driver's manual but either missed it or it's not there. When driving, if I press the button on the end of the turn signal stalk, it actuates the lane departure warning function. But I see two more 'dots' indicating, to me anyway, that there are two more functions to be actuated. What are these and what mode does the car have to be in for them to be functional? Or, point me to the relevant page in the manual.
