Stop and Start function

This system enables a reduced fuel consumption and lower greenhouse gas emissions.
The system is activated automatically when the vehicle is started. While driving, the system stops the engine (standby) when the vehicle is at a standstill (traffic jam, traffic lights, etc).

Conditions for engine standby

  • The vehicle has been driven since its last stop;
and
  • the gearbox is in D, Mor N position (refer to "Automatic gearbox" in Section 2);
and
  • the brake pedal is pressed (sufficiently hard);
and
  • and the accelerator pedal is not pressed;
and
  • the speed is zero for around 1 second.
The engine is kept on standby if P position (refer to the information on the "Automatic gearbox" in Section 2) is engaged or if N position is engaged and the parking brake is applied while the brake pedal is released.
The warning light on the instrument panel is lit when the engine is on standby.
The vehicle equipment remains operational while the engine is stopped.
