Starting and Driving
Traffic Sign Assist – TSA
( )
TSA detects traffic signs through the
use of a forward-facing digital camera
mounted on windshield, behind the rear-
view mirror and assists the driver by
displaying detected speed limits and
overtaking restrictions in the instrument
cluster. The camera also detects traffic
signs with a restriction indicated by an
additional sign (e.g. in snow conditions).
TSA also uses data of navigation system
to retrieve the speed limits when the
camera is not able to detect the road
where the car is traveling.
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 sign will be
displayed only in markets where this is
allowed.
• TSA provides a visual warning + chime
to the driver when he/she reaches the
speed limit.
• The performance of TSA does not
depend on the update degree of
navigation system’s maps.
Customized Settings
TSA is configurable by the customer
regarding the display mode on the MIA
screen.
Entering "Vehicle" page on MIA display
and select the "Traffic Sign Assist" soft-
key of the "Settings" menu to enter the
setting page.
The check mark on the "Warning Mode"
box can be set in "Off", "Visual" and
"Visual + Chime".
The display of the traffic signs can be
blinking or static.
Signs Monitoring on Instrument
Cluster
If TSA function is set and a sign or a
speed limit is detected, the related icons
are displayed in the upper area of the
instrument cluster or in the middle of the
screen beside the digital speedometer in
CORSA mode and in full map view.
The display area is divided in two
different sectors (only one for CORSA
mode):
1 Unconditional or Conditional Speed
Limit.
2 No Overtaking + Conditional Unverified
Speed Limit area.
NOTE:
Overtaking restriction sign will be
displayed only in markets where this is
allowed.
If “Visual or Visual + Chime” warning
mode is set, when the visual warning is
provided all icons (in sector 1 ) will start
blinking when the vehicle speed exceeds
the speed limit in area 1. If the vehicle
speed stays under the speed limit the
speed limit sign will stop blinking. If the
TSA is not able to determine any kind
of valid speed limit neither from camera
nor from digital maps, the icons will not
be displayed and a text message will
appear in the right View area.
Since TSA also uses the data provided
by the navigation system, it can update
the sector 1 of the display in the
following situations without detecting
traffic signs:
