Control system
The control system is activated as soon as
the SmartKey in the starter switch is
turned to position1 or as soon as the
KEYLESS-GO* start/stop button is in
position1. The control system enables you
to
call up information about your vehicle
change vehicle settings
For example, you can use the control sys-
tem to find out when your vehicle is next
due for service, to set the language for
messages in the instrument cluster dis-
play, and much more.
The control system relays information to
the multifunction display.
iThe displays for the audio systems
(radio, CD player etc.) will appear in En-
glish, regardless of the language se-
lected.
Warning!
G
A driver’s attention to the road and traffic
conditions must always be his /her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions
permit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approxi-
mately 14 m) every second.

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

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
arranged 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
instructions on using these submenus, see
“Submenus in the Settings menu”
(
page 149).
The number of menus available in the sys-
tem depends on which optional equipment
is installed in your vehicle.
The menus are described on the following
pages.
