ACC - Adaptive Cruise Control
Vehicles outside the sensor zone
Fig.136 Motorcyclist ahead out of range of
the radar sensor.
Fig.137 Vehicle changing lanes.
In the following situations the ACC may not
react, or may react slowly or inappropriately:
●
Vehicles that are not aligned while driving or
that are outside the sensor's detection area,
such as motorcycles ›››Fig.136.
●
Vehicles that move into your lane, a short
distance from your vehicle ›››Fig.137.
●
Vehicles with loads or accessories that pro-
trude from the sides, rear or roof.
Objects that are not detected
Fig.138 A vehicle turning and another
stationary.
The ACC function only detects and reacts to
vehicles moving in the same direction. There-
fore it does not detect:
●
People
●
Animals
●
Vehicles travelling in the opposite direction
or crossing the road.
●
Other stationary obstacles
The ACC may not react to stationary vehicles.
If, for example, a vehicle detected by the ACC
turns or moves over and there is a stationary
vehicle in front of it, the ACC will not react to
the second vehicle ›››Fig.138.
WARNING
Using the ACC in the above situations can
cause serious accidents and injuries, and you
could break the law.
Troubleshooting
ACC not available
The indicator lamp lights up yellow:
●
The radar sensor is dirty or adjusted in-
correctly. Take into account the warnings
described at the beginning of this chapter
›››page194
●
There is a fault or a defect. Turn o the vehi-
cle's ignition and turn it on again after a few
minutes.
●
If the problem persists, consult a specialised
workshop.
The ACC does not work as expected
●
Make sure that the conditions are met for the
radar sensor to operate properly ›››page194.
●
If the brakes overheat, regulation stops au-
tomatically. Wait for them to cool down and
check the operation again.
●
Unusual noises during automatic ACC brak-
ing are normal and do not indicate any anoma-
lies.
The following conditions may lead the ACC
not to react:
●
The accelerator or brake is depressed.
●
No gear is engaged or the vehicle is in gear R.
●
The vehicle is reversing.
