Many More Versions

Speed warning indicatorSpeed warning indicatorSpeed warning indicatorThe symbols here are pictorial representations of essentially the same thing, using a speedometer image with an arrow or a sign alongside. If a set passive speed limit is exceeded, the driver is alerted by an acoustic signal. In addition, the symbol indicating the speed limit is turned to yellow/amber. Finally, a pop-up message indicating that the limit has been exceeded will appear on display as well for a few seconds.

Overspeed indicatorOver speed warningSimilarly, several manufacturers use an Overspeed Warning Indicator. It has a single speed set into the system, which is 75 miles per hour, or 120 kilometers per hour (km/hr). It is a simple warning that illuminates if the speed is exceeded, with or without a greater than sign. A chime sounds for a few seconds as well.

Speed LimiterSpeed limiter assistThis pair are seen in green. The first icon with the dial with an arrow and the letters LIM indicate that its Manual Speed Limiter is on and functioning. In this case, the indicator will flash if the speed is exceeded. The Assist indicator tells the driver that speed limits will be detected and can be set manually.

Speed warning indicatorAs usual, there is seemingly no limit to the number of variations these warnings will take. This version will be seen in black and white in the information screen in the instrument panel, again when a speed set by the driver is exceeded. It shows either the letters MPH in the center or KPH in Canada or Europe for miles or kilometers per hour.
