your vehicle equipment was  factory-fitted.
The functions are operated by pressing and scrolling the controls   to   on 
the multi-function steering wheel  ⇒fig. 11 :•Press the   button   repeatedly to switch the display between the 
various modes and the phone book*    ⇒fig. 11 .•Scroll and press the left thumbwheel   to select a function from one of 
the menus.•The telephone speech control system*  ⇒page 86 is enabled by pressing
