The system limits of Tra1c Sign Assist apply to
th e de tection of tra1c signs (/ page 212).
Speed limits below 20 km/h are not automatical ly
adop tedby the system as the stored speed. Tem-
porary speed restrictions (e .g.fo r a cer tain time
or due towe ather conditions) cann otbe proper ly
de tected bythe system. The maximum permissi-

The speed adop tedby Active Speed Limit

individual cases, such as:
R at speed limits below 20 km/h R

R when towing a trailer #
Ensure that the driven speed complies
with tra1c regulations. #

When Active Distance Assist DISTRONIC is acti va-
te d, theve hicle speed will be adap ted accordingly
to thero ute events ahead. Depending on the drive
prog ram selected, theve hicle neg otiates a route
ev ent ahead in an economical, comfor table or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
stored speed. The set distance totheve hicle in
front, vehicles de tected ahead and speed restric-
tions ahead are take n into account.
Yo u can activate and deactivate route-based
speed adap tation in the multimedia system
(/ page 204).
The following route events are take n into account:
R Bends R
T-junctions, roundabouts and toll stations
R Turns and exits
R Tra1c jams ahead (only with Live Tra1c Infor-
mation )
% When theto ll station is reached, Active Dis-
ta nce Assist DISTRONIC ado ptsth e speed as
th e stored speed.
Also, the speed is reduced if the turn signal indi-
cator tochange lanes is switched on and one of
th efo llowing situations is de tected:
R Turning at junctions
R Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down
lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tojunctions, roundabouts and
tra1c lights, as route-based speed adap tation
does not brake theve hicle toa standstill.
When route guidance is active, the /rst speed

not steer theve hicle, a warning tone sounds in
addition tothe visual warning message.
If th e driver does not react tothewa rning for a

If th e driver steers, no warning is issued, or the

Ac tive Steering Assist has a limited steering tor-
qu efo r lateral guidance. In some cases, the steer-
ing inter vention is not su1cient tokeep theve hi-
cle in the lane or todrive thro ugh exits.
The system may be impaired or may not function
in thefo llowing instances:
R There is poor visibility, e.g. due tosno w,rain,
fo g, heavy spr ay,gr eatly varying light condi-
tions or strong shadow s onthe car riag ewa y.
R There is glare, e.g. from oncoming tra1c,
di re ct sunlight or re0ections.
R Insu1cient road illumination.
R The windscreen is dirty, mis ted up, damaged
or co vered in the vicinity of the camera, e.g.
by a stic ker.
R No, or se veral, unclear lane markings are pres-
ent for one lane, or the markings change
qu ickl y,fore xamp le, in a construction area or
junctions. R
The lane markings are wornawa y,dark or co v-
ered up, e.g. bydirt or sno w.
R Ifth e distance totheve hicle in front is too
short and thus the lane markings cannot be
de tected.
R The road is nar row and winding.
R There are obs tacles on the lane or projecting
out into the lane, suchas object mar kers.
The system does not pr ovide assistance in thefo l-
lowing conditions:
R On tight bends and when turning.
R When crossing junctions.
R Atroundabouts or toll stations.
R When towing a trailer.
R When the tyre pressure is too lo w. &

Ac tive Brake Assist can help youto minimise the
ri sk of a collision with vehicles, cyclists or pedes-
trians or toreduce the e.ects of such a collision.
If Ac tive Brake Assist has de tected a risk of colli-
sion, a warning tone sounds and theL dis-

cluster.
If yo u do not react tothewa rning, autonomous
braking can be initiated in critical situations.
In especially critical situations, Active Brake Assist
can initiate autonomous braking directl y.In this
case, thewa rning lamp and warning tone occur
simultaneously with the braking application. If
yo u 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 tomaxi-
mum full-s top braking if necessar y.

W WARNING
ARNING Risk of an accident caused by
limited de tection per form ance of Active
Brake Assist
Ac tive Brake Assist cannot alw ays clear lyiden-
tify objects and complex tra1c situations.
In such cases, Active Brake Assist might:
R Give a warning or brake without reason
R Not give a warning or not brake
Ac tive Brake Assist is only an aid. The driver is
re sponsible for maintaining a su1ciently safe
distance totheve hicle in front, vehicle speed
and for braking in good time. #
Always pay careful attention tothe tra1c
situation; do not relyonActive Brake
Assist alone. #
Be prepa redto brake or swer veif neces-

Ac tive Brake Assist is deactivated or the func-
tions are restric ted, e.g. due toactivation of
ano ther driving system, theê display message
