On roads with loose gravel.
•
Vehicles with no function to avoid overtaking
on the right
: On roads with several lanes, when
other vehicles are driving more slowly in the
overtaking lane.
Pay special attention when using ACC in the
following situations:
On curves
The ACC may not detect the vehicle in front
on a curve, or may regulate the distance from
vehicles in other lanes
Vehicles outside the sensor zone
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
.
•
Vehicles that move into your lane, a short
distance from your vehicle
.
•
Vehicles with loads or accessories that pro-
trude from the sides, rear or roof.
Objects that are not detected
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
WARNING
Using the ACC in the above situations can
cause serious accidents and injuries, and you
could break the law.
