This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops (
Ypage 26).
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for
the country in which you are currently driving
when operating the on-board computer.
GWARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The
operating safety of your vehicle may be
impaired. There is a risk of an accident.
Pull over as soon as it is safe to do so and
consult a qualified specialist workshop.
GWARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The
operating 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 immedi-
ately.
If the operating safety of your vehicle is
impaired, pull over as soon as it is safe to do
so. Contact a qualified specialist workshop.
The on-board computer only shows messages
or warnings from certain systems in the mul-
tifunction display. You should therefore make
sure your vehicle is operating safely at all
times.
For an overview, see the instrument panel
illustration (
Ypage 33).
Displays and operation
Instrument cluster lighting
The light sensor in the instrument cluster
automatically controls the brightness of the
multifunction display. In daylight, the displays in the instrument cluster are illuminated. A
dimming function is not possible in daylight.
The lighting in the instrument cluster, in the
displays and the controls in the vehicle inte-
rior can be adjusted using the brightness con-
trol knob.
The brightness control is located between the
instrument cluster and the COMAND Display
(
Ypage 35).
XTurn the brightness control knob clockwise
or counter-clockwise.
If the light switch (
Ypage 126) is set to
Ã, TorL, the brightness is
dependent upon the brightness of the
ambient light.
Tachometer
!
Do not drive in the overrevving range, as
this could damage the engine.
230Displays and operation
On-board computer and displays

The red band in the tachometer indicates the
engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached.
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 outside temperature display is in the mul-
tifunction display (
Ypage 232).
There is a short delay before a change in out-
side temperature is shown in the multifunc-
tion display.
Coolant temperature display
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
!A display message is shown if the coolant
temperature is too high.
If the coolant temperature is above 257 ‡
(125 †) do not drive any further. The
engine will otherwise be damaged.
The coolant temperature gauge is in the lower
section of the tachometer (
Ypage 33).
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 255 ‡ (124 †).

Head-up display
General notes
The head-up display projects information
from the navigation system and the driver
assistance system above the dashboard into
the driver's field of vision.
A requirement for the display of the contents
is that the following functions are available in
the vehicle and are switched on:
RCruise control
RDISTRONIC PLUS
RTraffic Sign Assist
RNavigation
The head-up display allows the driver to see
all of the information without having to take
his eyes off the road.
Important safety notes
The head-up display is only an aid and is not a
substitute for attentive driving.
Speed limits and overtaking restrictions are
not always correctly displayed. Traffic signs
always have priority over the Traffic Sign
Assist display.
The visibility of the head-up display is influ-
enced by the following conditions:
Rthe driver's seat position
Rthe positioning of the display image
Rthe general ambient light
Rsunglasses with polarization filters
Rwet roads
Rblocking of sunlight by objects on the dis-
play cover In the event of extreme sunlight, sections of
the display may fade. This can be reversed by
switching the head-up display off and on
again.
iVehicles with the head-up display are
equipped with a special windshield. Should
repairs be necessary, have the windshield
replaced at a qualified specialist workshop.
