adaptive cruise control
(ACC)
· Always adapt your speed and distance from the vehicle in
front according to visibility, weather, road and traffic
conditions.
Introduction to the topic
· Never use ACC in poor visibility, on steep, curvy or slippery
sections (eg in the event of snow, ice, rain or loose gravel),
or on flooded roads.
Adaptive cruise control (ACC = Adapti ve Cruise Control)
maintains a constant speed set by you. When the vehicle
approaches a vehicle in front, ACC automatically adapts the
speed and thus maintains the distance set by you.
· Never use ACC off-road or in
roads that are not firm ground. The ACC is intended for use
on paved roads only.
The ACC reacts in a limited way to vehicles

has ACC if settings for this system can be made in the vehicle
settings menu of the infotainment system ÿ p. 36.
· The ACC does not react to people or animals, or to vehicles
that cross or approach from the opposite direction in the
same lane.
Speed range ACC regulates
at speeds between 30 km/h (20 mph) and 210 km/h (130
mph). This range may vary depending on the market.
Brake immediately if ACC does not reduce the
speed enough.
· Brake immediately when a warning is displayed.

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.
· Brake when, after an indication to brake, the vehicle rolls
without this being desired.
· Always be prepared to regulate yourself my

If a trailer is attached, the ACC regulates with less dynamism.

Radar sensor
ACC detects driving situations using a radar sensor located at
the front of the vehicle. The range of this sensor is approx. 120 m
(400 ft).
WARNING
The intelligent technology of the ACC cannot cross the limits
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 any risk that compromises safety.
If used carelessly or inadvertently, it may cause

WARNING
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).
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. In this case, the radar
sensor may not detect obstacles that may be on the road. This
can cause accidents and serious injuries.
overtaking
· Check the road before each start of the journey and, if
necessary, brake the vehicle.
When you turn on the left turn signal (or the right turn signal when
driving on the left) to overtake, ACC accelerates the vehicle and
reduces the gap to the vehicle ahead without exceeding the speed
set by you.
ACC limitations
If ACC does not detect a vehicle ahead after changing lanes, it
accelerates the vehicle to the set speed.
