Situations where ACC may not function
optimally
WARNING
• The radar sensor has a limited field of
vision. In some situations it may detect
a vehicle later than expected or not
detect other vehicles at all.
• If ACC is not functioning properly,
cruise control will also be disabled.
Radar sensor's field of vision (shown in pink)
In certain situations, the radar sensor can-
not detect vehicles at close quarters, for
example a vehicle that suddenly enters the
lane between your vehicle and the target
vehicle.
Small vehicles, such as motorcycles, or
vehicles not driving in the center of the lane
may remain undetected.
In curves, the radar sensor may detect the
wrong vehicle or lose sight of the target
vehicle.
WARNING
• Adaptive Cruise Control cannot cover
all driving situations and traffic, weather
and road conditions. The "Function"
section provides information about lim-
itations that the driver must be aware of
before using this feature.
• This system is designed to be a supple-
mentary driving aid. It is not, however,
intended to replace the driver's atten-
tion and judgement. The driver is
responsible for maintaining a safe dis-
tance and speed and must intervene if
Adaptive Cruise Control does not main-
tain a suitable speed or suitable dis-
tance to the vehicle ahead.
• Maintenance of ACC components may
only be performed by a trained and
qualified Volvo technician.
