Operating the i-stop Function

(Mazda Radar Cruise Control (MRCC)/Cruising & Traffic Support (CTS) is not in use)

1. When the M Hybrid Boost system determines that the engine does not need power during driving, i-stop function operates and the i-stop indicator light (green) turns on.

   When AUTOHOLD is operating, the i-stop function continues to operate even if you release the brake pedal.

2. Start driving the vehicle.

   The engine restarts when the M Hybrid Boost determines that engine power is required.
