CITROËN C4 PICASSO Handbook page 181

While the direction indicators are on and for
a few seconds after switching them off, the
system considers that any change of trajectory
is voluntary and no correction is triggered
during this period.
However, with the "Blind spot monitoring
system" activated, if the driver starts changing
lane and another vehicle is detected in the
vehicle's blind spot, the system will correct
the trajectory of the vehicle even though the
direction indicators are on.
For more information on the Blind spot
monitoring system, refer to the corresponding
section.
If the system detects that the driver is
not holding the wheel firmly enough
during an automatic correction of
trajectory, it interrupts the correction.
An alert is triggered to encourage
the driver to take back control of the
vehicle.
Activation / Deactivation
Activation / deactivation of the system is done
in the Driving menu of the touch screen tablet.
Select the "Driving assistance" tab then
"Help staying in lane".
The state of the system stays in memory when
the ignition is switched off.
