Driving
No alert will be given and no correction will be
made in the following situations:
166
- in the presence of non-moving objects
(parked vehicles, barriers, street lamps,
road signs, etc.),
- with vehicles moving in the opposite
direction,
- driving on a winding road or a sharp corner,
- when overtaking or being overtaken by
a very long vehicle (lorry, bus, etc.) which is
both in the rear blind spot and present in the
driver's front field of vision,
- when overtaking quickly,
- in very heavy traffic: vehicles detected in
front and behind are confused with a lorry or
a stationary object,
- if the Park Assist function is activated.
Malfunction
If a fault occurs, this warning lamp comes on
in the instrument panel, accompanied by the
display of a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The system may suffer temporary
interference in certain weather conditions
(rain, hail, etc.).
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.
The system is automatically deactivated
when towing with a towing device
approved by CITROËN.
