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 set off from where it was parked;
For vehicles equipped with automatic gearboxes:
  • the gearbox is in D, N position or in manual mode;
and
  • the brake pedal is pressed (sufficiently hard);
If the warning light flashes while the vehicle is stationary and the "Press brake pedal" message appears on the instrument panel, this indicates that the brake pedal is not sufficiently pressed;
and
  • the accelerator pedal is not pressed;
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.
For vehicles equipped with manual gearboxes:
  • the gearbox is in neutral;
If the warning light flashes and the "Release Clutch pedal" message appears on the instrument panel, this indicates that the clutch pedal is not sufficiently released;
and
  • the clutch pedal is released;
and
  • the vehicle speed is less than approximately 3 mph (5 km/h).
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.
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.
WARNING
Keep your vehicle stationary when the engine is on standby (shown by the warning light on the instrument panel).
WARNING
Before leaving the vehicle, the engine must be switched off (and not put on standby) STARTING/STOPPING THE ENGINE: VEHICLE WITH KEYSTARTING, STOPPING THE ENGINE: VEHICLE WITH CARD.

Preventing the engine from standing by

In certain situations, such as negotiating a crossroads for instance, it is possible (with the system activated) to keep the engine on so as to be ready to move off quickly.
For vehicles equipped with automatic gearboxes and when the engine standby is performed only when the vehicle is stopped:
Keep the vehicle stationary without pressing too hard on the brake pedal.
For vehicles equipped with manual gearboxes:
Keep the clutch pedal pressed right down.
Tip
To fill up with fuel, the engine must be off (and not only on standby in the case of vehicles equipped with the Stop and Start function): you must switch off the ignition STARTING/STOPPING THE ENGINE: VEHICLE WITH KEY, STARTING, STOPPING THE ENGINE: VEHICLE WITH CARD.
Fire hazard.

Conditions for coming out of engine standby

For vehicles equipped with automatic gearboxes:
  • when the driver's door is opened;
or
  • when the driver's seat belt is unfastened;
or
  • the brake pedal is released, with D position or manual mode engaged;
or
  • when the brake pedal is released, N position is engaged and the parking brake is released;
or
  • the brake pedal is pressed again, P position is engaged or N position is engaged and the parking brake is applied;
or
  • the R position is engaged;
or
  • the accelerator pedal is depressed.
For vehicles equipped with manual gearboxes:
  • when opening the driver's door, without any gear engaged and the clutch pedal released;
or
  • when unfastening the driver's seat belt, without any gear engaged and the clutch pedal released;
or
  • the gearbox is in neutral position and the clutch pedal is slightly pressed;
or
  • the engine is in gear and the clutch pedal is pressed right down.
Special feature: depending on the vehicle, if you switch off the ignition when the engine is on standby, the warning light may be displayed for a few seconds on the instrument panel.
Tip
On vehicles equipped with a manual gearbox:
the restart may be interrupted if the clutch pedal is released too quickly while a gear is engaged.

Conditions preventing the standby of the engine
