directly. In this case, the warning lamp and warn-
ing t
one occur simultaneously with the braking
application.
If you apply the brake yourself in a critical situa-
tion or apply the brake during autonomous brak-
ing, situation-dependent braking assistance
occurs. The brake pressure increases up to maxi-
mum full-stop braking if necessary. If autonomous braking or situation-dependent
br

aking assistance has occurred, pop up 1
appears in the driver's display and then automati-
cally goes out aser a short time.
If the autonomous braking function or the situa-
tion-dependent braking assistance is triggered, additional preventive measures for occupant pro-
t
ection (PRE-SAFE n
) may also be initiated. &
WARNING Risk of an accident caused b
y
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly iden-
tify objects and com
plex traPc situations.
In such cases, Active Brake Assist might:
= Give a warning or brake without reason
= Not give a warning or not brake
Active Brake Assist is only an aid. The driver is
responsible for maintaining a suPciently safe
distance to the vehicle in front, vehicle speed
and for braking in good time. 
Always pay careful attention to the tr
aPc
situation; do not rely on Active Brake
Assist alone. 
Be prepared to brake or swerve if neces-
sar

y. If Active Brake Assist is deactivated or the func-
tions ar
e restricted, e.g. due to activation of another driving system, the
ê displa
y message
appears in the driver's display.

Function of Speed Limit Assist
%
Speed Limit Assist uses OpenStreetMap data,
whic h is made available under the conditions
of the Open Database License (OBbL). For
more information, see: https://
www.osmfoundation.org/wiki/licence.
Speed Limit Assist detects speed limits with multi-
function camer
a and displays them in the driver's
display and optionally in the head-up display. The
camera also detects speed limits with a restric-
tion indicated by an additional sign (e.g. when
wet).
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (  page 227).
Warning when the maximum permissible speed is
exceeded
The system can warn you if you unintentionally
exceed the maximum permissible speed. To do
this, you can specify in the multimedia system by how much the maximum permissible speed can
be e

xceeded before a warning is issued. You can
specify whether the warning is to be just a visual
warning or an acoustic one as well (  page 259).

3 Additional sign with restriction
% TraPc signs whic
h have an impact on the
maximum permissible speed, e.g. signs indi-
cating the beginning or end of dual carriage-
ways, can also be detected. The system can show up to two
tr
aPc signs in the
driver's display simultaneously. The system always
prioritises displaying speed limits. Up to one traf-
fic sign with a maximum permissible speed can be
shown in the head-up display. If two speed signs
are shown in the driver's display, forexample when
speed limits are detected, the value of les-hand
speed limit 1 is transmitted to the limiter, cruise
control or Active Distance Assist DISTRONIC for
adoption and is shown in the head-up display.
If Speed Limit Assist cannot determine the cur-
rent maximum permissible speed (e.g. due to
missing signs), the following display appears in
the driver's display: This is displayed continuously if the vehicle is in a
countr

y where Speed Limit Assist is not suppor-
ted. Speed Limit Assist is not available in all coun-
tries. 258

The sy
stem may be impaired or may not function
particularly in the following situations:
= If visibility is poor, e.g. due to insuPcient illu-
mination of the road, highly variable shade
conditions, rain, snow, fog, swirling dust or
heavy spray.
= If there is glare, e.g. from oncoming traPc,
direct sunlight or reOections.
= If there is dirt on the windscreen in the vicinity
of the multifunction camera or if the camera is
misted up, damaged or obscured.
= If traPc signs are diPcult to detect, e.g. due
to dirt, snow, ice, insuPcient lighting or driving
too close to the vehicle in front, or because
they are covered, faded, damaged, badly posi-
tioned or twisted.
= Digital LED traPc signs may not be detected
correctly or at all due to technical factors,
suchas transmission frequency.
= If signs or the road layout is ambiguous, e.g.
traPc signs in roadworks, at exits and ramps,
in neighbouring lanes or parallel roads. =
If signs do no t conform to the standard.
= If signs or road layouts are speciNc to the
country, forexample, at or beyond construc-
tion sites.
= Aser sharp turns and tight bends, when traPc
signs are outside the camera's Neld of vision.
= If you overtake vehicles with traPc signs
which are aPxed or attached to them.
= If you are using transport equipment secured
with a trailer coupling, suchas a bicycle rack,
the system may react to restrictions for car/
trailer combinations.

you by displaying detected speed limits and over-
taking restrictions in the driver's display and in
the head-up display. The system can issue a warn- Driving and parking

ing when you exceed the maximum permissible
speed.
In some countr
ies, the system can provide you
with further functions and can warn you when you
are approaching pedestrian crossings or when
you are about to drive past stop signs or red lights
unintentionally.
The camera also detects and analyses traPc
signs with a restriction indicated by an additional
sign (e.g. when wet).
TraPc Sign Assist portrays only selected signs in
the driver's display. Actual traPc signs and speed
limits have priority over traPc signs and speed
limits shown in the driver's display.
Also observe the following information:
= select a speed adapted to the traPc, sur-
roundings and weather conditions

TraPc
Sign Assis t can detect following additional
signs 3 and, if necessary, analyse the relevance
of the restrictions using other vehicle sensors:
= when wet
= slippery road surfaces
= in fog
= temporary restrictions
= exits
= restrictions for car/trailer combinations
TraPc Sign Assist also uses data from the digital
street map in the navigation system. When you
leave or enter a municipality or change roads, on
a motorway exit or slip road forexample, or aser
you turn at a junction, the display in the driver's
display can thus be updated without a traPc sign
having been detected.
If TraPc Sign Assist cannot determine the cur-
rently applicable maximum permissible speed
(e.g. due to missing signs), the following display
appears in the driver's display: TraPc

t is not available in all countries.
If the vehicle is in a country where TraPc Sign
Assist is not supported, this is displayed continu-
ously.
% Also observe the information on display mes-

Warning when the maximum permissible speed is
e
xceeded
The system can warn you if you unintentionally
exceed the maximum permissible speed. To do
this, you can specify in the multimedia system by
how much the maximum permissible speed can
be exceeded before a warning is issued. You can
set the warning to visual only (the traPc sign
Oashes three times in the driver's display) or vis-
ual and acoustic, including a warning tone.
Additional functions of TraPc Sign Assist (coun-
try-speciNc)
Warning for no-entry signs: TraPc Sign Assist can
warn you if you drive the wrong way down a sec- tion of road, forexample on motorway slip roads
or one-w
ay streets.
Warning at pedestrian crossings: if you approach
pedestrian crossings, provided that pedestrians
are in the danger zone or are moving towards it,
TraPc Sign Assist can warn you up to a speed of
approximately 70 km/h.
Warning at stop signs: TraPc Sign Assist can warn
you up to a speed of approximately 70 km/h if
you are about to drive past a stop sign uninten-
tionally. For this to be possible, the signs must be
clear, forexample if the system detects more than
one stop sign, or a stop sign can be conNrmed
using the digital navigation map. No warning can
be issued if several diMerent signs are detected.
Warning at red lights: TraPc Sign Assist can warn
you up to a speed of approximately 70 km/h if
you are about to drive through a red light uninten-
tionally.
The following conditions must be fulNlled:
= Several traPc lights have been detected.
= All traPc lights detected are red. Driving and parking
