Citroen C4: e-Auto mode (Hybrid)

The petrol engine stops when low power or torque is required and in stabilised conditions.

The petrol engine is restarted by the belt starter.

The e-Auto mode can switch off the petrol engine in the following cases:

- When the operating strategies permit.

- Vehicle speed up to 90 mph (145 km/h).

- When the driver releases the accelerator pedal in stabilised conditions or in deceleration.

- During the stop phases.

Restarting is only achieved by the belt starter until the torque demand is available, if the traction battery is sufficiently charged. When the torque demand is insufficient, the petrol engine restarts.

Using the steering wheel paddles also causes the restarting of petrol engine.

The e-Auto mode cannot switch off the petrol engine in the following cases:

- The state of charge is less than 30% of the traction battery energy.

- There is a need for vacuum brake assist depending on the altitude.

- The Sport mode is selected.

- Maintaining thermal comfort in the passenger compartment (heating, air conditioning, demisting/defrosting).
