Operating Limits
On good roads or motorways, the optimum set speed range is from 80 to 140 km/h.
Always observe the established speed limits.
The minimum adjustable speed is 30 km/h, and the maximum is 180 km/h.
The Active Cruise Control system does not relieve the driver of responsibility for maintaining a safe following distance.
The driver decides whether to use the system and, if so, to what extent, taking into account road surface condition, traffic density and visibility.
Use the system only in evenly flowing traffic. Do not use the system on roads with sharp curves, loose or slippery surfaces, or in heavy rain, snow or fog.
Monitor speed and distance and be ready to brake at any time.
Otherwise, you may violate traffic regulations and create a hazardous situation.◄
