Radar sensor - limitations
A radar sensor (p. 213) has certain limitations
- due to its limited field of vision for example.
The capacity of the adaptive cruise control to
detect a vehicle in front is significantly
reduced if:
•
the speed of vehicles in front is signifi-
cantly different from your own speed
•
its radar sensor becomes blocked - e.g.
in heavy rain or slush, or if other objects
have collected in front of the radar sen-
sor.
NOTE
Keep the area in front of the radar sensor
clean - see subheading "Maintenance"
(p. 233).
Field of vision
The radar sensor has a limited field of vision.
In some situations another vehicle is not
detected, or the detection is made later than
expected.
ACC field of vision.
Sometimes the radar sensor is late at
detecting vehicles at close distances -
e.g. a vehicle that drives in between the
car and vehicles in front.
Small vehicles, such as motorcycles, or
vehicles not driving in the centre of the
lane can remain undetected.
In bends the radar sensor may detect the
wrong vehicle or lose a detected vehicle
from view.
WARNING
The driver must always be observant with
regard to the traffic conditions and inter-
vene when the adaptive cruise control is
not maintaining a suitable speed or suita-
ble distance.
The adaptive cruise control cannot handle
all traffic, weather and road conditions.
Read all the sections about the adaptive
cruise control in the owner's manual in
order to learn about its limitations, of
which the driver should be aware before it
is used.
The driver always bears responsibility for
maintaining the correct distance and
speed, even when the adaptive cruise con-
trol is being used.
WARNING
Accessories or other objects such as auxil-
iary lamps must not be fitted in front of the
grille.
