2. Select the desired system on the screen of the  
instrument panel.  
Driving with ACC  
You can override ACC regulation at any time. If you brake, the  
regulation is interrupted. If it accelerates, the regulation is  
interrupted for the duration of the acceleration and is resumed  
afterwards.  
The speed limiter is deactivated.  
Depending on the equipment, the button is located on  
the multifunction steering wheel or the turn signal lever.

Driver intervention request  
If the automatic deceleration of ACC is not sufficient or  
the system limits have been reached, ACC prompts you

to brake additionally via a message in the instrument  
cluster. In addition, the red warning lamp lights up and  
an audible warning sounds. Take control of the vehicle

equipped with the traffic sign detection system and an infotainment  
system with navigation function, ACC can adapt the speed  
proactively to the detected speed limits and the route of the track  
(depending on equipment and not available in all countries).  
radar sensor  
ACC detects driving situations using a radar sensor located at  
overtaking  
the front of the vehicle. The range of this sensor is approx. 120m  
(approx. 400ft).  
When you turn on the left turn signal (or the right turn signal if  
driving on the left) to overtake, ACC accelerates the vehicle and  
reduces the distance from the vehicle ahead without exceeding  
the speed set by you.  
WARNING  
The intelligent technology of the ACC cannot cross the limits  
If ACC does not detect a vehicle ahead after changing lanes, it  
accelerates the vehicle to the set speed.  
imposed by the physical laws and only works within the limits  
of the system.  
Never let the increased comfort provided by this technology  
induce you to take risks that compromise safety. If used  
carelessly or inadvertently, it can cause accidents and serious  
injuries. The system cannot replace the driver's attention.  
This overtaking aid is not available in all countries.  
Heavy traffic with intermittent stops If the vehicle  
is equipped with an automatic transmission, ACC can brake the  
vehicle to a stop and hold it stopped. ACC remains active and  
ACC ready to start appears on the instrument panel display for  
a few seconds .  
· Always adapt your speed and distance from the vehicle in  
front according to visibility, weather, road and traffic  
conditions.

WARNING  
— On curvy routes, e.g. For example, on mountain roads.  
If the message ACC ready to go appears on the instrument  
cluster display and the vehicle ahead starts moving, your  
vehicle will automatically start driving. Given the case, it is  
possible that obstacles that could be on the road are not  
detected. This can cause accidents and serious injuries.  
— On cross-country journeys.  
— In covered car parks.  
— On tracks with embedded metal objects, e.g. eg,  
train or tram tracks.  
— On roads with loose gravel.  
· Check the road before each start of the journey and, if  
necessary, brake the vehicle.

delayed reaction  
When the radar sensor is exposed to environmental conditions  
that affect its performance, the system may detect this fact with  
a delay. For this reason, any operating limitations that may exist  
at the start of the journey and during the journey may be  
displayed after a delay ÿ p. 185.

When ACC detects a vehicle moving slower than yours in the  
left lane (or the right if you are driving on the left), ACC brakes
