PRINCIPLE OF OPERATION

WARNINGS
The system does not relieve you of
your responsibility to drive with due
care and attention.
At all times you are responsible for
controlling the vehicle, supervising
the system and intervening if
required.
If the sensor becomes blocked the
system may not function.
Lane markings may not always be
properly tracked by the sensor. Other
structures or objects may sometimes
be incorrectly detected as a lane marking,
resulting in a false or missed warning.
CAUTIONS
In cold and severe weather conditions
the system may not function. Rain,
snow, spray and large contrasts in
lighting can all influence the sensor.
The system will not operate if the
sensor cannot track the road lane
markings.
The system may not operate in areas
during roadworks construction.
The system may not operate on roads
with sharp bends or narrow lanes.
Do not carry out windshield repairs in
the immediate area surrounding the
sensor.
If your vehicle is fitted with a
suspension kit not approved by us, the
system may not function correctly.
Note: Keep the windshield free from
obstructions such as bird droppings, insects
and snow or ice.

Lane Departure Warning

163
Note: The system is intended as a driver aid
when driving on fast main roads and
highways.
Note: The system may not operate during
hard braking or acceleration and, when you
are intentionally steering the vehicle.
Note: The system will operate with a
minimum of one tracked lane marking.
Note: The system will only operate above
vehicle speeds of approximately 65 km/h
(40 mph).
A sensor is mounted behind the interior
rear view mirror. It continuously monitors
conditions to alert you of unintentional
lane drifting at high speeds.
The system will automatically detect and
track the lane markings on the road. If it
detects that the vehicle is unintentionally
drifting towards the lane boundaries then
a visual warning will be displayed in the
information display. There is also a warning
given in the form of a vibration felt through
the steering wheel.
