The TSR system displays the following types of road sign:
- A) Latest detected speed limit

The 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 multi-sensing front 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.)
When there is poor visibility. (For example, insufficient illumination of the road, bad weather conditions in rain, snow, fog or heavy spray.)
When the traffic signs are damaged or not standard. (For example, incorrect size, height, direction or brightness, broken or bent.)
When the traffic signs are hard to detect. (For example, they are covered by dirt or snow, or insufficient lighting.)
When the traffic signs are ambiguous. (For example, traffic signs on construction sites, in adjacent lanes or exit lane.)
When there is an object similar to traffic signs. (For example, similar signs, board or structure.)
When passing traffic signs are outside the camera’s field of vision. (For example, after a sharp turn or located too far away.)
When electric traffic signs are hard to detect. (For example, low contrast, located too far away or 3 digits.)
In areas not covered by the navigation system (where fitted).
If there are deviations in relation to the navigation (where fitted), for example due to changes in the road routing.
When overtaking buses or trucks with speed stickers.
When the data from the navigation system (where fitted) is not up-to-date or is unavailable.
The TSR system may display a traffic sign, even 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 trucks, different speed limit with the time of day or day of the week, or speed limit sign using different units near a border, when detecting an electric traffic sign with or without speed limit indication, when detecting an irrelevant speed limit passing by a freeway exit or junction, etc.）
