The principle of the Auto Stop & Go (AS&G) system is that it adapts to the vehicle’s needs (i.e. energy supply). This means that in certain circumstances the engine will not stop and in other circumstances the engine will restart by itself.

Circumstances when the engine will restart by itself

► The interior temperature rises and the air conditioning starts operating in order to lower the temperature.
► Electric power consumption is high.
► The brake pedal is depressed repeatedly.
► Vehicle speed is 3 km/h (2 mph) or higher when coasting on a slope.
► Mode selection dial is set to the demister position.
► When the air conditioning is operated by pressing the air conditioning switch.
► When the preset temperature of the air conditioning is changed significantly.
► When the air conditioning is operated in AUTO mode where the temperature control dial is set to the max. hot or the max. cool position (for vehicles with automatic air conditioning).

Other than the conditions mentioned above, the engine may restart automatically. For details, refer to “Auto Stop & Go (AS&G) system”.

Circumstances when the engine will not stop

► Ambient temperature is lower than approximately 3 °C.
► After the engine restarts automatically and the vehicle stops again within 10 seconds.
► After the engine restarts automatically and the vehicle remains stationary.
► Mode selection dial is set to the demister position (see illustration below).

► When the air conditioning is operated in AUTO mode where the temperature control dial is set to the max. hot or the max. cool position (for vehicles with automatic air conditioning).

Other than the conditions mentioned above, the engine may not stop automatically. For details, refer to “Auto Stop & Go (AS&G) system”.
