Intelligent Speed Assistance (ISA)
The ISA is a function which keeps the vehicle speed below the speed limit set from a speed limit sign or an optionally set speed limit. The speed limit can be set between 30 and 200 km/h (20-125 mph), and if the vehicle speed exceeds the set speed limit while driving on steep slopes, the system notifies the driver using the display and a warning sound.
The ISA recognises a speed limit sign based on the Traffic Sign Recognition System (TSR) or the navigation system information. Refer to Traffic Sign Recognition System (TSR) (Search).
Always turn off the system when changing drivers:
If the driver is changed and the new driver is unaware of the ISA function, the vehicle may not accelerate when the driver depresses the accelerator pedal, leading to an accident. Depending on the weather conditions or problems with traffic signs, a traffic sign may not be recognised or a traffic sign different from the actual traffic sign may be displayed. Always make it your responsibility as a driver to check the actual traffic signs. Otherwise, it could result in an accident.
The ISA operates only when the navigation system's SD card (Mazda genuine) is inserted.
The system consists of the ISA display and the speed limiter switch on the steering wheel.
