If you adjust the announced speed excessive-
ly, predictiv
e cruise control will be termina-
ted.
If a speed limit is detected, the predic-
tive cruise control function will adjust
the stored speed even if ACC is deactivated.
However, speed regulation will not take
place.
If the current speed significantly ex-
ceeds a speed limit detected by the
Dynamic Road Sign Display function, a warn-
ing will appear on the instrument cluster dis-
play.
When you join a motorway without
a speed limit, the recommended speed
will automatically be stored as the desired
speed. If a higher speed has previously been
stored on a motorway without a speed limit,
this will be adopted instead of the recom-
mended speed. Troubleshooting
Please refer to at the start of the chap-
ter on page 156.
A message is displayed that predictiv
e cruise
control is currently not available or is not
available in your country.

Limits of Front Assist
Please refer to at the start of the chap-
ter on page 159.
F
ront Assist is not available or its
functions are restricted immediately
after the vehicle is started. The indi-
cator lamp lights up in the instrument
cluster display during this time.
Front Assist has physical and system-related
limitations. You should therefore always be
prepared to take full control of the vehicle if
necessary.
Delayed response
If the camera or radar sensor is exposed to
environmental conditions that impair func-
tioning, the system may detect this only after
a certain delay. For this reason, any restric-
tions to functions may be displayed only after
a delay at the start of the journey and when
driving

Oncoming vehicle braking
when turning
Please refer to at the start of the chap-
ter on page 159. The oncoming vehicle braking when
turning function can pre
vent the vehicle
from colliding with an oncoming vehicle
during a turn.
If there is a risk of the vehicle colliding with
an oncoming vehicle in the adjacent lane
when turning, the oncoming vehicle braking
when turning function can brake your vehicle.
The vehicle can then remain in its own lane
as a result.
Speed range
The oncoming vehicle braking when turning
function is available up to around 15 km/h
(around 9 mph).
Limits
The oncoming vehicle braking when turning
function is available only if you indicate, have
turned the steering wheel and have therefore
started the turning manoeuvre. After chang-
ing from right-hand traffic to left-hand traf-
fic or vice versa, the oncoming vehicle brak-
ing when turning function is available only
after a certain time (30 minutes or more).
The oncoming vehicle braking when turning
function does not react to persons, animals,
crossing vehicles or objects that are not de-
tected as a vehicle. Always also observe the
fundamental limits of Front Assist

shown on the Head-up Display
