WARNING   WARNING:  Always switch the ignition off and fully apply the parking brake before carrying out any maintenance or leaving your vehicle. Failure to follow this instruction could result in personal injury or death if the engine restarts.

Principle of Operation
The system is designed to help reduce fuel consumption and CO2 emissions by stopping the engine when it is idling, for example at traffic lights. Your vehicle has an enhanced battery and starter motor that are designed for an increased number of engine starts.
The system does not stop the engine under certain conditions, for example:
  • If you have opened the driver door.
  • If you have unfastened the driver seatbelt.
  • If your vehicle is at high altitude.
  • If you have switched the heated windshield on.
  • If you have selected certain drive modes, for example sport.
  • If the engine is warming up.
  • If the outside temperature is too low or too high.
  • If the battery charge is low or the battery temperature is outside the optimal operating range.
  • To maintain the interior climate or reduce fogging.
The system restarts the engine under certain conditions, for example:
  • If you switch the heated windshield on.
  • If you switch maximum A/C or maximum defrost on.
  • If you turn the steering wheel.
  • If your vehicle starts to roll downhill in neutral.
  • To maintain adequate brake assistance.
  • To maintain the interior climate or reduce fogging.
Note:   The blower motor speed could change when the system restarts the engine.
