What can the braking guard do?
When de t ected in time, t he system can assess
dangerous sit uat ions where an object a head
brakes suddenly or if your own vehicle is traveling
at a high speed and approaching an object that is
mov ing more slowly. The brak ing guard does not
react if it cannot detect the situation.
The system advises you of various dangero us sit-
uations :
- The
distan ce warning occurs if you d rive t oo
closely to the object ahead for a long period of
time . If the object ahead brakes strongly, you
would not be able to avoid a collision . The .
indicator light appears as an indication for th is.
- The
approach warning occurs when an object
ahead is traveling more s low ly or brakes
strongly. When th is warning occurs, it may on ly
be poss ible to avoid a co llision by swerving or
braking strongly . The danger is indicated by the
• ind icator light

If you do not react early enough or at a ll to a dan-
ge rous situation, the braking guard suppo rts you
with a brak ing intervent ion . The approach warn-
ing indicators and the message

- If a collision is imminent, the system will first
provide a n
acute warning by braking sharply .
- If you do not react to the acute warning, the
brak ing guard can increase the braking force
withi n the limits of the system . This reduces
the vehicle speed in the event of a co llision.
- The system can init iate complete decelerat io n
sho rtly befo re a collis ion
l) . Full dece leration at
high speeds occu rs on ly in vehicles with adap-
t ive cr uise con t rol and side ass ist (pre sense
plus) .
- If the bra king g uard determines tha t you are
not brak ing st rongly eno ugh when t here is an
impending collision, it can increase the brak ing
force.
- The pre se nse functions also engage when
there is an impending collision

Which functions can be controlled?
You can switc h t he braking guard and t he d is-
tance/approach warning on or
off in the Infotain -
ment system

A WARNING
-
-
Lack of attention can cause collisions, other
accidents and ser ious personal inju ries . The
braking guard is a n assist system and cannot
prevent a collision by itself . The dr iver m ust
a lways inte rvene . The d river is always respon-
sib le for braking at the correct t ime .
- Always pay close atten t ion to traffic, even
when t he braking gua rd is switched on. Be
ready to int ervene and be rea dy t o take
comp lete cont rol wheneve r ne cess ary. Al-
ways keep the safe and legal d istance be -
tween your vehicle a nd ve hicles up ahead .
- Braki ng g uard works wit hin limit s a nd will
not respond outs ide the system limits, fo r
examp le when approac hing a stopped veh i-
cle or stationary obstacle (end of a traff ic
jam or vehicle that has broken down in traf -
fic).
- Always remember that the radar sensor for
the brak ing guard works only within def ined
detection and range limits that may prevent
the proper detect ion of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving vehicles up ahead may not be
promptly de t ected or may not be detected
at a ll.
- Reflective surfaces includi ng crash ba rriers
or tunne l entra nces may impair the function
of t he rad ar se nso r.
(D Tips
- You can cancel the braking with increas ing
force t ha t is initiated by t he sys t em by brak-
ing yourse lf, by acce le rat ing not iceably or
by swe rving.
