General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 60 km/h to
200 km/h speed range. If ATTENTION ASSIST
detects typical indicators of fatigue or increas-
ing lapses in concentration on the part of the
driver, it suggests taking a break.
Important safety notes ATTENTION ASSIST is only an aid. It may not
always detect fatigue or lapses in concentration
until too late, or may not detect them at all. The system is not a substitute for a well-rested and
attentive driver.
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or not
occur at all:
R if the length of the journey is less than approx-
imately 30 minutes
R if the road condition is poor, e.g. if the surface
is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R if you are predominantly driving at a speed
below 60 km/h or above 200 km/h
R if you are driving with the Steering Pilot of
Distance Pilot DISTRONIC activated
R if the time has been set incorrectly
R in active driving situations, such as when you
change lanes or change your speed
The evaluation of your attention level is deleted and restarted when continuing the journey, if:
R you switch off the engine
R you take off your seat belt and open the driv-
er's door, e.g. for a change of drivers or to
take a break 190

Displaying the attention level
You can have current status information dis-
played in the assistance menu (Y
page 207) of
the on-board computer.
X Select the assistance graphic display for
ATTENTION ASSIST using the on-board com-
puter (Y page 207).
The following information is displayed:
R the length of the journey since the last break
R the attention level determined by ATTENTION
ASSIST, displayed in a bar display in five levels from high to low
R if ATTENTION ASSIST is unable to calculate
the attention level and cannot output a warn-
ing, the System suspended
System suspended message
appears. The bar display then changes the
display, e.g. if you are driving at a speed below
60 km/h or above 200 km/h.
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 208).
The system determines the attention level of
the driver depending on the setting selected:
Standard selected: the sensitivity with which
the system determines the attention level is set
to normal.
Sensitive selected: the sensitivity is set higher.
The attention level detected by ATTENTION
ASSIST is adapted accordingly and the driver is
warned earlier.
When ATTENTION ASSIST is deactivated, the
À symbol and OFF appear in the multifunc-
tion display in the assistance graphics display
when the engine is running.
When ATTENTION ASSIST has been deactivated, it is automatically reactivated after the engine
has been switched off. The sensitivity selected corresponds to the last selection activated
(standard/sensitive).
Warning in the multifunction display If fatigue or increasing lapses in concentration
are detected, a warning appears in the multi-
function display:
Attention AttentionAssist:
Assist:Take
Takea
a
break!
break!
In addition to the message shown in the multi-
function display, you will then hear a warning
tone.
X If necessary, take a break.
X Confirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest. If you do not take a break, you will be warned again after
15 minutes at the earliest. This will only happen
if ATTENTION ASSIST still detects typical indi-
cators of fatigue or increasing lapses in concen- tration.
Vehicles with COMAND Online: if a warning is
output in the multifunction display, a service
station search is performed in COMAND Online. You can select a service station and navigation
to this service station will then begin. This func-
tion can be activated and deactivated in
COMAND Online. Traffic Sign Assist
General notes Traffic Sign Assist displays the maximum speed
permitted and overtaking restrictions to the
driver in the instrument cluster. Driving onto a
section of road in the wrong direction triggers a
warning. Traffic Sign Assist detects traffic signs with camera system :attached behind the top Driving syste

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 whenoperating 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 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.
The on-board computer only shows messages or warnings from certain systems in the multifunc-tion display. You should therefore make sure
your vehicle is operating safely at all times.
If the operating safety of your vehicle is
impaired, park the vehicle safely as soon as pos- sible. Contact a qualified specialist workshop.
For an overview, see the instrument cluster illus-
tration (Y page 32). Displays and operation
Instrument cluster lighting
The lighting in the instrument cluster, in the dis- plays and the controls in the vehicle interior can
be adjusted using the brightness control knob.
The brightness control knob is located on the
bottom left of the instrument cluster
(Y page 32). X
Turn the brightness control knob clockwise or
anti-clockwise.
If you turn the light switch (Y page 113) to the
Ã, TorL position, the brightness
will depend upon the brightness of the ambi-
ent light.
The light sensor in the instrument cluster
automatically controls the brightness of the
multifunction display. In daylight, the displays in the instrument cluster are not illuminated. Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
R Cruise control activated (Y page 159):
The segments light up from the stored speed to the maximum speed.
R Variable speed limiter is activated
(Y page 170):
The segments light up from the start of the
scale to the selected limit speed.
R Distance Pilot DISTRONIC is activated
(Y page 161):
One or two segments in the set speed range
light up.
R Distance Pilot DISTRONIC detects a vehicle in
front moving more slowly than the stored
speed:
The segments between the speed of the vehi-
cle in front and the stored speed light up. Rev counter
! Do not drive in the overrevving range. Doing
so will damage the engine.
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 condi-
tions when temperatures are around freezing
point.
Bear in mind that the outside temperature dis-
play indicates the measured air temperature
and not the road surface temperature. Displays and operation

The outside temperature display is in the multi-
function display (Y page 201).
A change in the outside temperature is shown in
the multifunction display after a delay. Coolant temperature gauge

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 coolant temperature gauge is in the instru-
ment cluster on the right-hand side (Y page 32).
Under normal operating conditions and at the
correct coolant level, the coolant temperature
may rise to 120 †.
At high outside temperatures and when driving
uphill, the coolant temperature may rise to the
end of the scale. Operating the on-board computer
