When ATTENTION ASSIST is deactivated, the
ésymbol appears in the multifunction dis-
play in the assistance graphic display.
When ATTENTION ASSIST has been deactivated,
it is automatically reactivated after the engine
has been stopped. The sensitivity selected cor-
responds to the last selection activated ( Stand‐
ard/Sensitive).
Warning in the multifunction display
If fatigue or increasing lapses in concentration
are detected, a warning appears in the multi-
function display:ATTENTION
ASSIST:TakeaBreak!.
In addition to the message shown in the multi-
function display, you will then hear a warning
tone.
XIf necessary, take a break.
XConfirm 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 properly. If you do
not take a break and ATTENTION ASSIST con-
tinues to detect increasing lapses in concentra-
tion, you will be warned again after 15 minutes
at the earliest. This will only happen if ATTEN-
TION ASSIST still detects typical indicators of
fatigue or increasing lapses in concentration.
If a warning is given in the multifunction display,
the multimedia system offers a service station
search. You can select a service station and
navigation to this service station will then begin.
This function can be activated and deactivated
in the multimedia system.
Traffic Sign Assist
General notes
Traffic Sign Assist displays the maximum speed
permitted to the driver in the instrument cluster.
The data and general traffic regulations stored in
the navigation system are used to determine the
current speed limit.
Traffic Sign Assist is a map-based system, and
for this reason, traffic signs put up temporarily
(e.g. near roadworks) are not detected. There is also no display for changing traffic signs.
Traffic signs with a restriction indicated by an
additional sign (e.g. in wet conditions) are also
shown. The sign indicating the end of a restriction only
appears with the restriction in the instrument
cluster when:
Rthe regulation must be observed with the
restriction, or
RTraffic Sign Assist is unable to determine
whether the restriction applies
If Traffic Sign Assist is unable to determine a
maximum permitted speed from any of the avail-
able sources, no speed limit appears in the
instrument cluster either.
Traffic Sign Assist is not available in all coun-
tries. In this case, display :appears in the
assistance graphic (
Ypage 198).
Important safety notes
Traffic Sign Assist is only an aid and is not always
able to correctly display speed limits. Traffic
signs always have priority over the Traffic Sign
Assist display.
The system may be either functionally impaired
or temporarily unavailable if the information in
the digital street map of the navigation system is
incorrect or out of date.
Activating Traffic Sign Assist
XActivate the Traffic Sign Assist display using
the on-board computer (Ypage 199).
If you have activated the Traffic Sign Assist dis-
play in the on-board computer, the traffic regu-
lations (speed limits and overtaking restrictions)
appear in the instrument cluster for five seconds in each case. The wrong-way warning and the
traffic sign display for speed limits and overtak-
ing restrictions remain active even when the
display has been deactivated.

Rthe radar sensors in the front or rear bumpers
or the radiator trim are dirty, e.g. obscured by
snow
Rthere are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work
Rthe lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
Rthe distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
Rthe lane markings change quickly, e.g. lanes
branch off, cross one another or merge
Rthe road is narrow and winding
Rthere are strong shadows cast on the road
If no vehicle is detected in the adjacent lane and
broken lane markings are detected, no lane-cor-
recting brake application is made.
Warning vibration in the steering wheel
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 second s.
In orde r that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system recognizes certain conditions
and warns you accordingly.
The warning vibration occurs earlier if:
Ryou approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a highway.
Rthe system recognizes solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.
Ryou cut the corner on a bend.
Lane-correcting brake application
If you leave your lane, under certain circumstan-
ces the vehicle will brake briefly on one side.
This is meant to assist you in bringing the vehicle
back to the original lane.
GWARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
GWARNING
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropriate brake application, e.g. after intentionally driv-
ing over a solid lane marking. There is a risk of
an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance on the side for
other traffic or obstacles.
If a lane-correcting brake application occurs,
display :appears in the multifunction display.
The brake application also slightly reduces vehi-
cle speed.
A lane-correcting brake application can be made
after driving over a lane marking recognize as
being solid or broken. Before this, a warning
must be given by means of intermittent vibration
in the steering wheel. In addition, a lane with
lane markings on both sides must be detected.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. The following vehicles can
have an influence on brake application: oncom-
ing traffic, vehicles that are overtaking and vehi-
cles that are driving parallel to your vehicle.
A further lane-correcting brake application can
only occur after your vehicle has returned to the original lane.

Coolant temperature gauge
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 34).
Under normal operating conditions and with the
specified coolant level, the coolant temperature
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. The Head-up Display allows the
driver to see all of the information without hav-
ing to take their eyes off the road.
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
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 display
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 equip-
ped with a special windshield. Should repairs
be necessary, have the windshield replaced at
a qualified specialist workshop.
