lock.
Warning lamps :in the exterior mirrors
light up red for approximately 1.5 second s.
Grey radar waves propagating backwards
appear next to the vehicle in the assistance
display in the multifunction display. Active Lane Keeping Assist General notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of multi-
function camera :at the top of the wind-
screen. Various different areas to the front,
rear and side of your vehicle are also moni-
tored with the aid of the radar sensor system. Active Lane Keeping Assist detects lane
markings on the road and can warn you
before you leave your lane unintentionally. If
you do not react to the warning, a lane-cor-
recting application of the brakes can bring the
vehicle back into the original lane.
This function is available within a speed range between 60 km/h and 200 km/h.
Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of an accident nor override the laws of
physics. Active Lane Keeping Assist cannot
take account of road and weather conditions. It may not detect traffic situations. Active
Lane Keeping Assist is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in lane.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane. G
WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings. Driving systems

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 26). Important safety notes
G
WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for
the country in which you are currently driving when operating the on-board computer. G
WARNING
If the instrument cluster has failed or there is a malfunction, you may not know about
safety-related function restrictions. The oper-ating safety of your vehicle may be affected.
There is a risk of an accident.
Immediately stop the vehicle while paying
attention to the traffic conditions and consult
a qualified specialist workshop. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions 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, park the vehicle safely as soon as
possible. Contact a qualified specialist work-
shop.
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 cluster
illustration (Y page 32). 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
(Y page 34).
X Turn the brightness control knob clockwise
or anti-clockwise.
If the light switch (Y page 128) is set to
Ã, TorL, the brightness is
dependent upon the brightness of the
ambient light. Rev counter
! Do not drive in the overrevving range.
Doing so will damage the engine. 244
Displays and operationOn-board computer and displays

The red band in the rev counter 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 measured air tempera-
ture and not the road surface temperature.
The outside temperature display is in the mul- tifunction display (Y page 246).
There is a short delay before a change in out- side temperature is shown in the multifunc-
tion display. Coolant temperature gauge
G
WARNING
If you open the bonnet while the engine is
overheating or while there is a fire in the
engine compartment, you could come into
contact with hot gases or other leaking ser-
vice products. There is a danger of injury.
Allow an overheating engine to cool down
before opening the bonnet. If there is a fire in the engine compartment, leave the bonnet
closed and notify the fire brigade.
The multifunction display shows the coolant
temperature gauge in the lower section of the rev counter (Y page 32).
At high outside temperatures and when driv-
ing uphill, the coolant temperature may rise.
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 124 †. Operating the on-board computer

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:
R Cruise control and SPEEDTRONIC
R DISTRONIC PLUS
R Traffic Sign Assist
R Navigation
The head-up display allows the driver to see
all of the information without having to take
their 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:
R the driver's seat position
R the positioning of the display image
R the general light conditions R
sunglasses with polarisation filters
R wet road surfaces
R blocking 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.
i Vehicles with the head-up display are
equipped with a special windscreen.
Should repairs be necessary, have the
windscreen replaced at a qualified special-
ist workshop.
