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 button è or ÿ
repeatedly, you will pass through each
menu one after the other.
If you press button k or j
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 instructions on using these
submenus, see "Settings menu"
( page 163).
The number of menus available in the sys-
tem depends on which optional equipment
is installed in your vehicle.
