Ov
ertaking
If you indicate left (left-hand traffic: indicate
right) to overtake, ACC will accelerate the ve-
hicle and reduce the distance from the vehi-
cle in front. Your set speed will not be excee-
ded.
If ACC does not detect any vehicle in front af-
ter you have changed lane, ACC will acceler-
ate the vehicle up to the set speed.
Overtaking assistance is not available in all
countries.
Stop-and-go traffic
ACC can brake the vehicle to a standstill and
keep it stationary. ACC remains active and
the instrument cluster display shows
ACC ready
to start for a few seconds.
On vehicles with Travel Assist, you can extend
this time by continuing to hold the steering
wheel.
As long as ACC remains active, the vehicle
will move off again automatically as soon as
the vehicle in front moves off (depending on
the vehicle equipment level and not available
in all countries).

Advance warning
The system detects a possible colli-
sion and prepares the vehicle for pos-
sible emergency braking.
An acoustic warning sounds and the red
warning lamp lights up. Brake or take avoid-
ing action.
Urgent warning
If the driver does not react to the advance
warning, the system may initiate a short
braking jolt in order to draw attention to the
increasing collision risk. Brake or take avoid-
ing action.
Automatic braking
If the driver also does not react to the urgent
warning, the vehicle can be braked automati- cally with braking force that increases in sev-
eral stages. The reduced speed means that it
is possible to minimise the consequences of
an accident.
Braking interv
ention
If the system detects that the driver is brak-
ing insufficiently when there is a risk of colli-
sion, the system can increase the braking
force and help prevent a collision. The brak-
ing intervention takes place only for as long
as the brake pedal is pressed hard.
Distance warning
The system detects when safety
is endangered by driving too
close to the vehicle in front. The indi-
cator lamp lights up. Increase the dis-
tance.
Speed range: around 65 km/h (around
40 mph) to around 250 km/h (around
155 mph). Area monitoring system 161

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
