Control system
Pressing any of the buttons on the multi-
function steering wheel will alter what is 
shown in the multifunction display.
The information available in the multifunc-
tion display is arranged in menus, each 
containing a number of functions or sub-
menus.
The individual functions are then found 
within the relevant menu (radio or CD op-
erations under 
AUDIO
, for example). These 
functions serve to call up relevant informa-
tion or to customize the settings for your 
vehicle.It is helpful to think of the menus, and the 
functions within each menu, as being ar-
ranged in a circular pattern.
If you press buttonè orÿ 
repeatedly, you will pass through each 
menu one after the other.
If you press buttonk orj 
repeatedly, you will pass through each 
function display, one after the other, in 
the current menu.In the 
SETTINGS
 menu, instead of functions 
you will find a number of submenus for 
calling up and changing settings. For in-
structions on using these submenus, see 
the “Settings menu” section (
page 132).
The number of menus available in the sys-
tem depends on which optional equipment 
is installed in your vehicle.
iThe headings used in the menus table 
are designed to facilitate navigation 
within the system and are not neces-
sarily identical to those shown in the 
control system displays.
The first function displayed in each 
menu will automatically show you 
which part of the system you are in.
