Traffic Sign Assist – TSA
(optional) TSA detects traffic signs through the
use of a forward-facing digital camera
mounted on windshield, behind the
rear-view mirror. TSA assists the driver
by displaying on the instrument
cluster detected speed limits and
traffic signs with a restriction
indicated by an additional sign (e.g. in
snow conditions). TSA also uses the
data of the navigation system, in
order to provide information to the
driver in all cases in which the camera
is not able to detect the traffic signs
that are present on the road where
the car is travelling.
Some examples of these are: due to
low visibility, light reflection, damaged
traffic signs, traffic signs in wrong
position like rotated or fallen poles.
NOTE:
• Overtaking restriction signs are not
displayed by the TSA system.
• TSA provides a visual warning to the
driver when he/she unintentionally
reaches the maximum speed limit
allowed or when it exceeds the set
“Sensitivity” value. • The performance of TSA depends on
the update degree of navigation
system’s maps.
Customised Settings TSA is configurable by the customer
regarding the display mode on the
instrument cluster and the warning
sensitivity.
Entering "Controls" page on MTC+
display the driver can see the current
setting beside the "Traffic Sign Assist"
soft-key.
Touching “Traffic Sign Assist” soft-key
can disable or enable the system.
Touching the soft-key on the side the
driver can change the setting.
The display of the traffic signs can be
blinking or static.
The system can be set to display the
traffic signs when the speed of the
vehicle is equal to the speed limit allowed, or when it is higher than 5 or
10 mph (5 or 10 km/h).
Signs Monitoring on
Instrument Cluster
If TSA feature is set and a signs or a
speed limit is detected, the related
icons are displayed in the upper area
of the instrument cluster beside of the
main menu number and scroll arrows.Driving

The display area is divided in two
different sectors:
1 Conditioned speed limit area.
2 Unconditioned speed limit area.
NOTE:
Overtaking restriction signs are not
displayed by the TSA system.
If “Blinking On” warning mode is set,
when the visual warning is provided
only the unconditioned speed limit (in
sector 2 ) will start blinking when the
vehicle speed exceeds to the detected
unconditioned speed limit (“+0 mph”
or “+0 km/h” option) or when it
exceeds the set sensitivity value
(“+5 mph” - “+5 km/h” or “+10 mph” -
“+10 km/h” options). If the vehicle
speed stays above the unconditioned
speed limit for several seconds the
unconditioned speed limit sign will stop blinking because the manoeuvre
is evaluated as intentional. If the TSA is
not able to determine any kind of
valid speed limit neither from camera
nor from digital maps the following
image will be shown in sector 2 .
Since TSA also uses the data provided
by the navigation system, it can
update the sector 2 of the display in
the following situations without
detecting traffic signs:
• When the vehicle changes road.
• Highway enter/exit.
• Urban area stored in the digital map
enter/exit.
System Limitations TSA may be impaired or may not
function in the following situations:
• If there is poor visibility, e.g. due to
insufficient illumination of the road,
if there are highly variable shade
conditions or in rain, snow or fog.
• If there is glare, e.g. from oncoming
traffic, direct sunlight or reflections
from other vehicles.
• If the windshield in the area of the
camera is dirty, or if the camera is
fogged up, damaged or covered.
• If the traffic signs are hard to detect,
e.g. due to dirt or snow, or because they are covered or because of
insufficient lighting.
• If the information in the navigation
system's digital map is incorrect or
out-of-date.
• If the signs are ambiguous, e.g.
traffic signs on construction sites or
in adjacent lanes.
• When passing buses or trucks with a
speed sticker.Driving
