Important safety notes
G
WARNING
Operating the integrated information sys-
tems
and
communications equipment in the
vehicle while driving will distract you
from traffic conditions. You could then
lose control of the vehicle. There is a risk
of an accident.
Only operate these devices if road traffic
conditions permit. If you are unsure about
the surrounding conditions, pull over to a
safe location and make entries only while
the vehicle is stationary.
You must observe the legal requirements for
the country in which you are currently driv-
ing when operating the on-board computer.
G
WARNING
If the instrument cluster has failed or mal-
functioned,
you
may not recognise function
restrictions relevant to safety. The oper-
ating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle
checked at a qualified specialist workshop
immediately.
The on-board computer only shows display
messages and/or warnings from certain sys-
tems in the display. You should therefore
make sure your vehicle is operating safely at
all times. Otherwise, you may cause an acci-
dent by driving a vehicle that is not operat-
ing reliably.
If the operating safety of your vehicle
impaired, park the vehicle as soon as possi-
ble paying attention to road and traffic con-
ditions. Contact a qualified specialist work-
shop.

Displays and operation
Instrument cluster lighting
Instrument cluster
lighting includes illumi-
nation of the instrument cluster, the addi-
tional instruments on the dashboard, the dis-
plays and the controls.
The instrument cluster lighting is switched
automatically between day and night lighting
depending on the ambient light conditions
(Y page 72).
On vehicles with a colour display, you can
also set the brightness of the instrument
cluster lighting to different levels in the on-
board computer (Y page 129).
Speedometer
If you turn the key to position 2 in the igni-
tion
lock,
the warning and indicator lamps in
the instrument cluster will briefly light up
for a lamp test. During the lamp test, the
illuminated speedometer needle moves in the
speedometer.
The on-board computer with a colour display
can show a digital speedometer in the dis-
play. The digital speedometer can be hidden/
displayed and its speed unit selected
(Y page 129).
Outside temperature display
You should
pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The display shows the outside temperature on
the far right in the header:
R
monochrome display (Y page 122)

colour display (Y page 124)
Changes in the outside temperature are dis-
played after a short delay.
If the outside temperature has fallen below
3 †, the Ò symbol is shown beside the out-
side temperature display.
