ACC: clutch applied

Vehicles with manual transmission: pressing
●
the clutch pedal for longer exits cruise con-
trol.
Door open
Vehicles with automatic transmission: the
●
ACC cannot be activated with the vehicle
stationary and the door open.
WARNING
There is a danger of rear collision when the
distance to the vehicle in front is reduced
and the speed difference between both ve-
hicles is so great that a speed reduction by
the ACC is not sufficient. In this case, brake
immediately!
The ACC may not be able to detect all
●
situations properly.
Stepping on the accelerator may cause
●
the ACC not to intervene in braking. Driver
braking will have priority over intervention
by the speed control or adaptive cruise
control.
Always be ready to use the brakes!
●
Observe country-specific provisions gov-
●
erning obligatory minimum distances be-
tween vehicles.
It is dangerous to activate control and re-
●
sume the programmed speed if the road,
traffic or weather conditions do not permit
this. Risk of accident!

Driving
Note
The programmed speed is erased once
●
the ignition or the ACC are switched off.
When the traction control (TCS) is deac-
●
tivated or else the ESC is activated in
›››
Sport* Mode ( page 87), the ACC
switches off automatically.
In vehicles with the Start-Stop system,
●
the engine switches off during the ACC
stopping phase and restarts for moving off.
Function to prevent overtaking on
the right
On the instrument panel display: ACC
Fig. 166
active, vehicle detected in an outer lane.
The ACC has a function to prevent overtaking
on the right.
If another vehicle is driving more slowly to the
left of the vehicle, it is shown on the display
›››
Fig. 166.
The system brakes the vehicle to avoid over-
taking on the right, and will avoid overtaking
based on speed. The driver can interrupt the
intervention of the ACC by pressing the ac-
celerator. At low speeds the function is inac-
tive, for greater comfort in a traffic jam or in
city traffic.
Deactivating the ACC temporarily
in certain situations
In the following situations the ACC should be
deactivated due to the system's limitations
›››
:
When overtaking, on closed curves or
●
mountain roads, roundabouts, slip roads or
roadwork sections, preventing the system
from accelerating to reach the programmed
speed.
When going through a tunnel, as operation
●
could be affected.
When other vehicles are going slower in the
●
left lane. In this case, slower vehicles will be
overtaken on the right.
In case of heavy rain, snow or fog, the vehi-
●
cle in front may not be detected.
