replace the need for vigilance on the part

of the driver.

The driver must observe the driving

regulations and must adapt the speed of

the vehicle to suit the weather and traffic.

It is possible for the system to not display

the speed limit if it does not detect a

Recognition of

speed limit signs and

recommendation

The units for the speed limits (km/h or

mph) depend on the country in which you

are driving.

This should be taken into account in order

to observe the speed limit.

For the system to operate correctly when

you change country, the units for speed in

the instrument panel must be set to those

for the country in which you are driving.

To maintain correct operation of the

system: regularly clean the area in front of

the camera.

The internal surface of the windscreen can

also become misted around the camera.

In humid and cold weather, demist the

windscreen regularly.

This system allows the speed limit detected by

the camera to be displayed in the instrument

panel.

The system also processes speed limit details

from the navigation system mapping.
