If
th e system de tects that the driver has not
steered theve hicle for a considerable period of
time or has remo vedth eir hands from the steering
wheel, display 1appears. If the driver still does
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
considerable period, the system can initiate an
emer gency stop (/ page 207).
If th e driver steers, no warning is issued, or the
wa rning is ended.
If Ac tive Steering Assist de tects that a system
limit has been reached, a visual warning is issued
and a warning tone sounds. Obser

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-
ta nce warning lamp lights up in the inst rument
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.
Obser vethe no tes on driving systems and your
re sponsibility; you may otherwise failto recognise
dangers (/ page 185). If autonomous braking or situation-dependent
braking assistance has occur

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-
sar y. If
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
appears in the driver's displa y.208 208

If
th e system is una vailable due todirty or dam-
