h
e content of the traffic sign display can be
cleared. To view available settings from the
infotainment screen, touch Settings >Display

provided by the navigation system map data.
In some cases, traffic sign memory is cleared
automatically by the system.

when the system is reset.
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. If the map data
is unavailable, Traffic Sign Assistant will turn
off automatically.
Limitations
Tr
affic sign memory may not operate
correctly if:
•
The area of the windshield, 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The navigation map data is out of date.
•
The navigation map is unavailable.
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 system can be ready to assist at speeds
between approximately 60 km/h (37 mph) and
180 km/h (112 mph). On some vehicles, the
system will instead operate above 50 km/h
(31 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
centered in the lane. LKA will not assist and
alert if the turn signal is active, 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.
