Right-Side Function Buttons
Pressing the L button signals the EGS (TCM) to engage the "Limiting program". The limiting mode is indicated on the instrument cluster display by the letter "L" when active. Pressing the button again restores the normal drive program.
Pressing the "up/down" rocker button activates the radio station search function. When a compact disc is playing, touching the rocker button moves playback to the next/previous track. With a telephone, it can be used to scroll through the stored phone book.
The bottom button is a programmable-function button with Key Memory function. The Key Memory function allows the button to be programmed differently for different drivers (keys).
The "Settings" menu in the Control Display offers a choice of functions such as "Automatic Hold" (automatic parking brake operation) and "Air Recirculation" for which the button can be programmed.
Those functions are selected using the controller. The button is then assigned the selected function.
