Driving
- when overtaking (or being overtaken by) a
very long vehicle (lorry, coach...) which is
at the same time detected at the rear in the
blind spot angle and present in the driver's
forward field of vision,
- in very heavy traffic: vehicles detected in
front and behind are confused with a lorry
or a stationary object,
- when overtaking quickly.

F to deactivate the system, press
this button again; the warning
lamp goes off.
the state of the system remains in memory on
switching off the ignition.
the system is automatically deactivated

PeugeOt.
Operating fault
In the event of a fault, the warning
lamp in the button flashes then
goes off.
Have it checked by a PeugeOt dealer or a
qualified workshop.
the system may suffer temporary
interference in certain weather
conditions (rain, hail...).
In particular, driving on a wet surface
or moving from a dry area to a wet area
can cause false alerts (for example, the
presence of a fog of water droplets in
the blind spot angle is interpreted as a
vehicle).
In bad or wintry weather, ensure that
the sensors are not covered by mud, ice
or snow.
take care not to cover the warning zone
in the door mirrors or the detection
zones on the front and rear bumpers
with adhesive labels or other objects;
they may hamper the correct operation
of the system.
