Control system
Depending on the selected menu, pressing
the buttons on the multifunction steering
wheel will alter what appears in the multi-
function display.
The information available in the multifunc-
tion display are arranged in menus and
accompanying functions or submenus.
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 button è or ÿ re-
peatedly, you will pass through each
menu one after the other.

If you press button k or j re-
peatedly, 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
“Settings menu” (
page 157).
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.

Warning!G
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the
hands-free device and only use the tele-
phone when weather, road, and traffic con-
ditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a
vehicle.
Bear in mind that at a speed of just
30 mph (approximately 50 km/h), your
vehicle is covering a distance of
44 feet (approximately 14 m) every second.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system,
possibly resulting in an accident and/or
personal injury.

Driving systems
If only the red distance segments illumi-
nate and no acoustic warning sounds, the
Parktronic system sensors are dirty or
there is an interference from other radio or
ultrasonic signals. The Parktronic system
will automatically switch off after
20 seconds and the indicator lamp in the
Parktronic switch comes on.
Switch off the ignition (page 40).
Clean the Parktronic system sensors
(
page 337).
Switch on the ignition (page 40).
or
Check the Parktronic system operation
at another location to rule out interfer-
ence from outside radio or ultrasonic
signals.
