Brake Assist
Active Brake Assist cannot always clearly iden-
tify objects and com
plex traPc situations. In such cases, Active Brake Assist might:
= Giv

e 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 display message
appears in the driver's display.
If the system is unavailable due to dirty or dam-
aged sensors or due to a fault, or if the functions

raPc Sign Assist
% This function is an on-demand feature
(  pag

e 26).
TraPc Sign Assis
t detects traPc signs with the
multifunction camera and compares this with
information in the digital navigation map. It assists
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-
ing when you exceed the maximum permissible
speed.
In some countries, 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 Assis
t 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
= observe actual traPc signs
= observe applicable traPc rules and regula-
tions
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers ( page 263). Driving and parking

3 Additional sign with restriction
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 or
Active Distance Assist DISTRONIC for adoption
and is shown in the head-up display. Examples of
tr
aPc signs which can be displayed
TraPc Sign Assist can detect and display following
traPc signs 1:
= speed limits
= end of the speed limit
= overtaking restrictions
= play streets
= depending on the country: signs showing the
start or end of motorways and dual carriage-
ways 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: 292

TraPc
Sign Assis 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-
sag
es in TraPc Sign Assist (  page 503).
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. =
A t least one of the red traPc lights detected is
on the front passenger side beside the vehi-
cle's own lane.
= The traPc lights are in the following sequence
(from top to bottom): red, yellow, green.
% If the function is available, you can activate or
deactiv
ate the warnings at pedestrian cross-
ings, stop signs and red lights in the TraPc
Sign Assist menu under Further warnings
(  page 294).
