q Function of Active Lane Change Assist
Active Lane Change Assist supports the driver during lane changes by applying steering torque if
the driver activates a turn signal indicator.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize dangers (  page 170).
Assistance during lane changes is provided if all
the following conditions are met:
= You are driving on a freeway or road with mul-
tiple lanes in the direction of travel.
= The neighboring lane is separated by a broken
lane marking.
= No vehicle is detected in the adjacent lane.
= The vehicle speed is between 50 mph
(80 km/h) and 110 mph (180 km/h).
= Active Lane Change Assist is switched on in
the multimedia system.
= Active Steering Assist is activated and active.
If no vehicle is detected in the adjacent lane and a
lane change is permitted, the lane change begins
aser the driver has activated the turn signal indi-
cator. This is shown to the driver with a green
arrow next to the

&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 althoughthe 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 limitations of Active Steering Assist
apply to Active Lane Change Assist (  page 187).
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, forexample.
= 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 or
available only partially during this teach-in
process; no arrow appears next to the Ø

qFunction of Active Brake Assist
Active Brake Assist consists of the following func-
tions:
= Distance warning function
= Autonomous braking function
= Situation-dependent braking assistance
= Vehicles with Driving Assistance Package: Eva-
sive Steering Assist and cornering function
Active Brake Assist can help you to minimize the risk of a collision with vehicles, cyclists or pedes-
trians or to reduce the eMects of such a collision.
If Active Brake Assist has detected a risk of colli- sion, a warning tone will sound and the / dis-
tance warning lamp will light up on the instrument cluster.
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 will occur at the same time as the braking.
Driving and parking191

If you apply the brake yourself in a critical situa-
tion or apply the brake during autonomous brak-
ing, situation-dependent braking assistance will
occur. The brake pressure will increase up to max- imum full-stop braking if necessary.
Observe the notes on driving systems and your responsibility; you may otherwise fail to recognizedangers (  page 170).
If autonomous braking or situation-dependent
braking assistance has occurred, indicator 1 will
appear on the instrument display and then auto-
matically go out aser a short time.
&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
will appear on the driver\bs 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

TraPc Sign Assist

qFunction of TraPc Sign Assist
TraPc Sign Assist detects traPc signs with the
multifunction camera (  page 171). It assists
you by displaying detected speed limits and over- taking restrictions in the Instrument Display.
Observe the notes on driving systems and yourresponsibility; you may otherwise fail to recognize
dangers (  page 170).
Since TraPc Sign Assist also uses the data stored
in the navigation system, it can update the display in the following situations without detecting traPc
signs.
The camera also detects traPc signs with a
restriction indicated by an additional sign (e.g.
when wet). These are displayed only if a restric-
tion applies or if the system cannot clearly deter-
mine whether the restriction applies.
Warning when the maximum permissible speed is
exceeded
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 specify whether the warning is to be just a visualwarning or an acoustic one as well.

\f symbol next to a traPc sign in the Instru-
ment Display indicates that additional traPcsigns have been detected. These can also be
displayed in the media display and optionally in the head-up display.
If TraPc Sign Assist cannot determine the maxi-
mum permissible speed (e.g. due to missing
signs), the following display appears in the Instru- ment Display:
This is displayed continuously if the vehicle is in a
country where TraPc Sign Assist is not supported.
