134 Controls in detailInstrument clusterOutside temperature indicator
The outside temperature is displayed in
the left or right multifunction display
(page 24), depending on the setting
(page 149).The temperature sensor is located in the
front bumper area. Due to its location, the
sensor can be affected by road or engine
heat during idling or slow driving. There-
fore, the accuracy of the displayed temper-
ature can only be verified by comparison to
a thermometer placed next the sensor, not
by comparison to external displays, e.g.
bank signs, etc.
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

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 posi-
tion 1. 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.
Multifunction display
The multifunction display consists of the
display fields in the speedometer and the
tachometer. In its default state, the left
multifunction display shows the main
odometer and the digital speedometer,
while the trip odometer appears in the
right multifunction display. This default
setting is referred to as the standard dis-
play.

5Automatic transmission program mode
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, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit 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 (approximate-
ly 14 m) every second.

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

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

you will find a number of submenus for
calling up and changing settings. For in-
structions on using these submenus, see
“Settings menu” (page 146).
The number of menus available in the sys-
tem depends on which optional equipment
is installed in your vehicle.
