116 Controls in detailInstrument clusterOutside temperature indicator
The outside temperature is displayed in
the multifunction display (
page 123).
For information on selecting the tempera-
ture display unit, i.e. degrees Celsius (°C)
or degrees Fahrenheit (°F), see “Selecting
temperature display mode” (page 131).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 displays caused by heat radiated
from the engine during idling or slow driv-
ing.
Trip odometer
Make sure you are viewing the stan-
dard display menu (
page 122).
Press and hold reset buttonJuntil
the trip odometer is reset.
Clock
Vehicles with COMAND*:
The clock in the instrument cluster can be
synchronized with the time set in
COMAND using the time synchronization
with head unit feature (
page 133), or set
independently from COMAND using the
control system (
page 134) with the time
synchronization with head unit feature set
to
Off
.
For setting the time in COMAND, see sep-
arate COMAND operating instructions.
For setting the time with audio system,
(
page 134).
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.

mit it to be done safely.
