DRIVING AND OPERATING
Navigation System Traffic Sign
Detection
The currently displayed sign can
either originate from sign detection
using the camera, or from the
navigation system map data. If the
currently displayed sign originates
from map data and the map
information changes, a new sign will
be displayed. This may lead to
detection of a new sign, although no
sign on the road may have been
passed.
Limitations
Traffic sign memory may not operate
correctly if:
.
The area of the windscreen, where
the front camera is located, is not
clean or is affected by foreign
objects, e.g. stickers, window
tinting, etc.
.
Traffic signs are completely or
partially covered, are too low or
high or difficult to discern.
.
Traffic signs are incorrectly
mounted or are damaged.
.
Traffic signs do not comply with the
approved traffic sign standards.
.
The speed limit is displayed by
certain types of electronic speed
signs.
.
There are adverse environmental
conditions, e.g. heavy rain, snow,
direct sunlight or shadows.
.
The headlights are dirty or not
correctly aligned when driving at
night.
.
The navigation map data is out
of date.
Lane Keep Assist (LKA)
If equipped, LKA may help avoid
crashes due to unintentional lane
departures. This system uses a camera
to detect lane markings. The LKA may
be ready to assist at speeds between
50 km/h (31 mph) and 180 km/h
(112 mph). LKA may assist by gently
turning the steering wheel if the
vehicle approaches a detected lane
marking. It may also provide a Lane
Departure Warning (LDW) alert if the
vehicle crosses a detected lane
marking. This system is not intended
to keep the vehicle centred in the
lane. LKA will not assist and alert if
the indicator is active in the direction
of lane departure, or if it detects that
you are accelerating, braking or
actively steering. LKA can be
overridden by turning the steering
wheel. If the system detects you are
steering intentionally across a lane
marker, the LDW will not be given. Do
not expect the LDW to occur when
you are intentionally crossing a lane
marker.
{
Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a lane
marking is detected.
The LKA and LDW systems
may not:
.
Provide an alert or enough
steering assist to avoid a lane
departure or crash.
.
Detect lane markings under poor
weather or visibility conditions.
This can occur if the windscreen
or headlamps are blocked by dirt,
