Mazda Safety Technology - Intelligent Speed Assist (ISA) Explained

Intelligent Speed Assist (ISA) is a function which keeps the vehicle speed below the speed limit set via Traffic Sign Recognition (TSR) or manually via the vehicle's steering wheel controls. The speed limit can be set for speeds above 30 km/h 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.

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, which could potentially lead to an accident.

SETTING THE VEHICLE SPEED LIMIT VIA TRAFFIC SIGN RECOGNITION

To activate ISA, press the LIM switch on the steering wheel. Once activated, the LIM speed, i.e. the road speed the vehicle is now limited to, will illuminate within the multi-information display and Active Driving Display.

MANUALLY SETTING THE VEHICLE SPEED LIMIT FROM A SPEED LIMIT SIGN

To manually activate the system the driver will first need to press the LIM switch on the steering wheel, then the RES switch while the ISA set indication is displayed. To cancel ISA, the driver can either press the CANCEL button on the steering wheel, fully depress the accelerator pedal, undo the driver’s seat belt or open any door. Please note, depressing the brake pedal does not cancel ISA.

It's important that you check the owner’s manual on each vehicle for the systems specific operating conditions.
