With Uconnect™ without
navigation system
The TSR system uses the camera,
located in the central area of the
windscreen fig. 174 and reminds the
user of the last road limit recognised by
the camera.

F0S1286
NOTE Without a navigator, the system
cannot provide:
the implicit limits (e.g. the general
speed limit on motorways). In these
cases the system can show the last
road sign encountered (e.g. the speed
limit of the entrance ramp);
in general, the limit in force for a
road where a speed limit sign was not
previously encountered and correctly
recognised.
After travelling a certain distance, the
road limit symbol turns grey to indicate
that it is no longer considered reliable
by the system. Upon recognition of a
new sign, the TSR symbol will become
coloured again.
WARNING In the absence of a
navigator, the system cannot recognise
the unit of measurement of the
country you are travelling in, but only
the numerical value of the road sign
encountered along the road. The
speed limit suggested and offered
to Intelligent Speed Assist (ISA) and
Intelligent Adaptive Cruise Control
(IACC) systems (where active) is
therefore intended according to the unit
of measurement set by the user on the
instrument panel display. Therefore, for
the ISA and the IACC to be of practical
help in complying with the limits in
force, the driver must set the unit of
measurement consistent with the
country in which they are travelling.
With Uconnect™ with navigation
system
When the navigator is present, the TSR
system integrates the detections made
by the camera with the information
provided by the navigation system.
Therefore, it can provide the implicit
limits (e.g. the general speed limit on
motorways) and to supplement with
maps the limitations of recognition of
road signs on the camera alone.
The navigator tells the system of the
unit of measurement in force in the
country in which you are travelling and
converts the value consistently with the
unit of measurement selected by the
user. In this way, the speed limitation
suggested by the ISA system or the
speed offered by the IACC system will
always be correct, regardless of the
unit of measurement chosen by the
user.
The system can display the shape of
the signs consistently with the current
shape of the country in which you are
travelling.
Using the information contained in the
navigator, the system can recognise
motorway, urban and non-urban
scenarios and to use the limits
provided by the navigator to provide
the most plausibly accurate speed limit.
In addition, the system can recognise
turns and provide, where necessary,
the limit detected by the navigator
in place of that recognised by the
camera.
