PRINCIPLE OF OPERATION
WARNINGS
The system is not a collision warning
or avoidance system. The separate
forward alert function provides a
collision warning and mitigation feature.
See Forward alert function (page 158).
You must intervene if the system does not
detect a vehicle in front.
When driving you are responsible for
maintaining the correct distance and
speed, even when adaptive cruise
control is used. You must always pay
attention to the traffic conditions and
intervene when adaptive cruise control is
not maintaining a suitable speed or
suitable distance.
The system does not relieve you of
your responsibility to drive with due
care and attention.
The system does not brake for slow
or stationary vehicles, pedestrians,
objects in the road, oncoming and
crossing vehicles.
CAUTIONS
Only use adaptive cruise control when
conditions are favourable, for example
on motorways and main roads with
steady free flowing traffic.
Do not use in poor visibility,
specifically fog, heavy rain, spray or
snow.
Do not use on icy or slippery roads.
Do not use the system when entering
or leaving a motorway.
The radar sensor has a limited field of
vision. In some situations it may
detect a vehicle other than the one
expected or not detect any vehicle at all.
Note: When adaptive cruise control is
activated, you may hear some unusual
sounds during automatic braking. This is
normal and caused by the automatic
braking system.
Note: Keep the front of the vehicle free
from dirt, metal badges or objects, including
vehicle front protectors and additional lights
which may prevent the sensor from
operating.
The system is designed to help you
maintain a gap from the vehicle ahead or
a set road speed if there is no slower
vehicle ahead. The system is intended to
provide enhanced operation of the vehicle
when following other vehicles which are in
the same lane and travelling in the same
direction.
The system is based on the use of a radar
sensor which projects a beam directly
forward of the vehicle. This beam will
detect any vehicle ahead within the
system's range.
The radar sensor is mounted behind the
front grille.
