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. During driving, the system stops the engine (standby) when the vehicle comes to a stop or is moving at a slow speed (traffic jam, traffic lights, etc), depending on the vehicle.

Conditions for engine standby

The vehicle has set off from where it was parked ;
  • the gearbox is in position D, M or N ;
and
  • the brake pedal is depressed (sufficiently hard) ;
Depending on the vehicle, if the warning light flashes and that the message “Press brake pedal” appears on the instrument panel, this indicates that the brake pedal is not sufficiently pressed ;
and
  • the accelerator pedal is not depressed ;
and
  • when the vehicle speed is zero during approximately one second or, depending on the vehicle, as soon as the vehicle speed is below approximately 3 mph (5 km/h).
The engine remains on standby if position P is selected, or if position N is selected with the handbrake engaged and the brake pedal released.
Warning light on the instrument panel is lit when the engine is on standby.
The vehicle equipment remain operational while the engine is stopped.
When the engine switches to standby, the steering assistance may no longer be operational.
In this case it becomes operational again when the engine is no longer on standby or the speed exceeds approximately 1 mph (1 km/h) (downhill, slope etc.).
WARNING
If the engine is put in standby, the electronic parking brake (depending on the vehicle) is not applied automatically.
