responsible for complying with road traPc regula-
tions and driving at a suitable speed.
The speed adaptation made by the system may
not always be suitable, particularly in the following situations:
= the road\bs course not clearly visible
= Road narrowing
= varying maximum permissible speeds in indi-
vidual lanes, forexample at toll stations
= wet road surfaces, snow or ice
In these situations the driver must intervene
accordingly.&WARNING Risk of accident in spite of
route-based speed adaptation
Route-based speed adaptation can malfunc-
tion or be temporarily unavailable in the fol-
lowing situations:
= If the driver does not follow the calculated
route
= If map data is not up-to-date or available
=
In the event of roadworks
= In bad weather or road conditions
= If the accelerator pedal is depressed
= In the event of electronically displayed
speed limitationsAdapt the speed to the traPc situation.

qFunction of Active Steering Assist
Active Steering Assist is only available up to a
speed of 130 mph (210 km/h). The system helps you to stay in the center of the lane by means ofmoderate steering interventions. Depending on
the speed driven, Active Steering Assist uses the vehicles ahead and lane markings as a reference.
\bDepending on the country, in the lower speedrange Active Steering Assist can use the sur-
rounding traPc as a reference. If necessary,
Active Steering Assist can then also provide assistance when driving outside the center of
the lane, forexample, to form a rescue lane.
If the detection of lane markings and vehicles
ahead is impaired, Active Steering Assist switches to passive mode. The system provides no support
in this case.

status, the Ø symbol is shown as enlarged

Active Steering Assist may be unavailable.
Steering and touch detection
The driver is required to keep their hands on the steering wheel at all times and be able to inter-
vene at any time to correct the course of the vehi-
cle and keep it in lane. The driver must expect a change from active to passive mode or vice versa at any time.If the system detects that the driver has not
steered the vehicle for a considerable period of time or has removed their hands from the steeringwheel, display 1 appears. If the driver still does
not steer the vehicle, a warning tone sounds in
addition to the visual warning message.
If the driver does not react to the warning for a
considerable period, the system can initiate an
emergency stop ( page 177).
The warning is not issued or is stopped when the driver gives conNrmation to the system:
= The driver steers the vehicle.
=Depending on the country: the driver presses
a steering wheel button or operates Touch Control
If Active Steering Assist detects that a system limit has been reached, a visual warning is issuedand a warning tone sounds.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize dangers ( page 158).
System limits
Active Steering Assist has a limited steering tor-
que for lateral guidance. In some cases, the steer-
ing intervention is not suPcient to keep the vehi-
cle in the lane or to drive through exits.
The system may be impaired or may not function
in the following instances:
= There is poor visibility, e.g. due to snow, rain,
fog, heavy spray, greatly varying ambient light
or strong shadows on the road.
= There is glare, e.g. from oncoming traPc,
direct sunlight or reOections.
= *nsuPcient road illumination.176Driving and parking

If the system is impaired, Active Lane Change
Assist may be canceled. If it is canceled, the Lane Change Canceled message appears on the
instrument display.
In addition, a warning tone may sound, depending on the situation.&WARNING Risk of accident when changing
lane to an occupied adjacent lane
Lane Change Assist cannot always clearly detect if the adjacent lane is free.
The lane change might be initiated although
the adjacent lane is not free.
Before changing lanes, make sure that
the neighboring lane is free and there is
no danger to other road users.Monitor the lane change.&WARNING Risk of accident if Lane Change
Assist unexpectedly stops functioning
If the system limitations for Lane Change
Assist have been reached, there is no guaran-
tee that the system will remain active.
Lane Change Assist cannot then assist you by
applying steering torque.Always monitor the lane change and
keep your hands on the steering wheel. Observe the traPc conditions and steer
and/or brake if necessary.
System limits
The system limits of Active Steering Assist apply to Active Lane Change Assist ( page 175).
The system may also be impaired or may not func-
tion in the following situations:
= The sensors in the rear bumper are dirty, dam-
aged or covered by a sticker or ice and snow, for example.
= The exterior lighting shows a defect.
\bThe Active Lane Change Assist sensors adjust
automatically while a certain distance is being
driven aser the vehicle has been delivered.
Active Lane Change Assist is unavailable dur-
ing this teach-in process; no arrow appears next to the Active Steering Assist symbolØ when the turn signal indicator is activa-
ted.

If Active Brake Assist has detected a risk of colli-
sion, a warning tone sounds and the / warn-
ing lamp lights up.
Vehicles with PRE-SAFE n
: depending on the coun-
try, an additional haptic warning occurs in the form of slight, repeated tensioning of the seatbelt.
If you do not react to the warning, autonomous
braking can be initiated in critical situations.
In especially critical situations, Active Brake Assist
can initiate autonomous braking directly. In this
case, the warning lamp and warning tone 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 brake force boosting. The brake pressure increases up to maximum full-
stop braking if necessary.
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognizedangers ( page 158).
If autonomous braking or situation-dependent
brake force boosting has occurred, display 1
appears in the instrument display and then auto-
matically goes out aser a short time.
If the autonomous braking function or the situa- tion-dependent brake force boosting is triggered,
additional preventive measures for occupant pro-
tection (PRE-SAFE n
) may also be initiated.
&WARNING Risk of an accident caused by
limited detection performance of Active
Brake Assist
Active Brake Assist cannot always clearly iden-
tify objects and complex 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 traPc
situation; do not rely on Active Brake
Assist alone.Be prepared to brake or swerve if neces-
sary.
If Active Brake Assist is deactivated or the func- tions are restricted, e.g. due to activation ofanother driving system, the ê display message
appears on the instrument display.
If the system is unavailable due to dirty or dam-
aged sensors or due to a malfunction, or if the
functions are restricted, the
