If you remove the warning stickers, you or
others could be injured by failing to recognise
certain dangers.
When driving yourv ehicle observe the follow-
ing information:
R the safety notes in this manual
R the "Technical data" section in this manual
R traffic rules and regulations
R laws and safety standards pertaining to
moto rvehicles Implied warranty
! Observe the notes in these Operating
Instructions about the correct operation of
your vehicle as well as about possible dam-
age to the vehicle. Damage to your vehicle
that arises from culpable contravention of
these instructions is not covered by the
Mercedes-Benzi mplied warranty of
Daimler AG. Data stored in the vehicle
Fault data
Components critical for vehicle operation are
equipped with fault data memories as stand-
ard. There are also data storage devices
which record the technical reactions of vehi-
cle components to certain driving situations
(e.g. airbag deployment or ESP ®
interven-
tion).
This data is used exclusively to:
R assist in the rectificatio noffaults and
defects
R help Mercedes-Ben zoptimise and develop
vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced by Mercedes-
Benz, this technical information can be read
out from the fault memory. This is performed
by authorised employees of the Mercedes- Ben
zservice network using special diagnos-
tic computers.
After a fault has been rectified, the informa-
tion is deleted from the memory. Other mem-
ory data is constantly overwritten. Other devices that store data
Depending on the equipment level, your vehi-
cle may feature communications and/or
entertainment systems (e.g. navigation devi-
ces, telephone systems). These allow you to
save and edit data required for the operation
of the respective device.
Further information on operation (e.g. on
deleting data) can be found in the separate
operating instructions. Introduction

detected message appears in the multi-
function display.
X If necessary, take a break.
X Press the abutton to confirm the mes-
sage.
On long journeys, take regularb reaks in good
time to allow yourself to rest properly.Ify ou
do not take a break, you will be warned again
after 15 minutes at the earliest. The precon-
dition for this is that ATTENTION ASSIST still
detects typical indicators of fatigue or
increasing lapses in concentration.
ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con-
tinue your journey if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break. Speed Limit Assist
General notes Speed Limit Assist shows you detected speed
limits in the multifunction display .Data from
the navigation system is also used for this
purpose. If a traffic sign indicating a speed
limit or the end of a speed limit is detected,
it is shown in the multifunction display. If
Speed Limit Assist does no tdetec tany traffic
signs, the speed limit from the digital road
map is take nand shown in the display.
Speed Limit Assist detects the traffic signs
with a camera attached behind the top of the
windscreen. :
Speed Limit Assist camera
Important safety notes G
WARNING
Speed Limit Assist is onl yanaid and may
detect speed limit signs incorrectly or not at
all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R there is glare, e.g. from the sun or from
oncoming traffic.
R the windscreen is dirty, misted up or cov-
ered, for instance by a sticker, in the vicinity
of the camera.
R the traffic signs are covered, for instance
by dirt, snow or trees.
R the traffic signs are poorly illuminated.
R there are ambiguous traffic signs, for
instance near roadworks or on multi-lane
roads.
Traffic signs always have priority over the
Speed Limit Assist display. Speed Limit Assist
cannot detect road and traffic conditions. It is
not a substitute for attentive driving.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others. 176

J
The red brake system
warning lamp comes on
while the engine is run-
ning. A warning tone
also sounds. There is insufficient brake fluid in the brake fluid reservoir.
G WARNING
The braking effect may be impaired.
There is a risk of accident.
X Pull over and stop the vehicle safely as soon as possible, paying
attention to road and traffic conditions. Do not continue driving
under any circumstances.
X Engage the electric parking brake.
X Do not top up the brake fluid. Topping up will not remedy the
fault.
X Consult a qualified specialist workshop.
X Observe the additional display messages in the multifunction
display. !
The yellow ABS warning
lamp is lit while the
engine is running. ABS (Anti-lock Brake System) has been deactivated due to a fault.
For this reason, BAS (Brake Assist), BAS PLUS, ESP ®
(Electronic
Stability Program), PRE-SAFE ®
, the HOLD function, hill start assist,
the adaptive brake lights and ESP ®
trailer stabilisation are also
deactivated, for example.
ATTENTION ASSIST is deactivated.
G WARNING
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.
This limits the steerability of the vehicle when braking and may
increase the braking distance.
If ESP ®
is deactivated or not operational, the vehicle's stability
during standard driving manoeuvres is reduced.
There is a risk of accident.
X Observe the additional display messages in the multifunction
display.
X Drive on carefully.
X Visit a qualified specialist workshop.
If the ABS control unit is faulty, there is also a possibility that other
systems, such as the navigation system or the automatic trans-
mission, will not be available. Warning and indicator lamps in the instrument cluster

24-GHz radar sensor system (country overview)
The 24 GHz radar sensor system requires separate approval for each country. If you are driving
in a country in which the radar sensor system is not approved, you must deactivate the system
using the on-board computer (Y page 203).
The current country overview can be obtained from a Mercedes-Benz Service Centre.
Vehicles with anavigation system: the radar sensor system is deactivated automatically
near radio telescope facilities. Adisplay message appears in the multifunction display to tell
you that the radar sensor system is being switched off (Y page 222).
If Blind Spot Assist is active, it will be deactivated automatically (Y page 177).
If the deactivation does not occur automatically, you must deactivate the radar sensor system
using the on-board computer (Y page 203).
