The Traffic Sign Recognition (TSR) system is intended as an aid to careful driving. It is the driver’s responsibility to stay alert, drive safely, and observe all road regulations that currently apply, including looking out for road signs.
The TSR system may not function properly under all conditions. Below are some examples:
When rain, snow or dirt adheres to the windscreen in front of the TSR camera unit.
When the headlights are not bright due to dirt on the lens or if the aiming is not adjusted properly.
When strong light enters the camera unit. (For example, the light directly shines on the front of the vehicle at sunrise or sunset.)
When a sudden change in brightness occurs. (For example, when the vehicle enters or exits a tunnel or under a bridge.)
In areas not covered by the navigation system.
If there are deviations in relation to the navigation, for example due to changes in the road routing.
When overtaking buses or trucks with speed stickers.
When the data from the navigation system is not up-to-date or is unavailable.
The TSR system may display a traffic sign, though there is no traffic sign in front of the vehicle. It may display a different speed limit from that for a passenger vehicle. (The maximum speed limit sign may show a higher or lower number than the actual maximum speed, for example, when detecting a speed limit sign for truck, advisory sign, different speed limit sign between daytime and night-time, or speed limit sign written in a different unit near the border, etc.)
