BLIND SPOT SENSORS
This driving assistance system warns
the driver of the presence of another
vehicle in the blind spot angle of their
vehicle (areas masked from the driver's
fi eld of vision), as soon as this presents
a potential danger.
Operation
)
On switching on the ignition, or en-
gine running, press this button to
activate the function; the warning
lamp comes on.
This system is designed to im-
prove safety when driving and is
in no circumstances a substitute
for the use of the interior rear
view mirror and door mirrors. It
is the driver's responsibility to
constantly check the traffi c, to
asses the distances and relative
speeds of other vehicles and
to predict their movements be-
fore deciding whether to change
lane.
The blind spot sensor system
can never replace the vigilance
and responsibility of the driver.
Sensors fi tted in the front and rear bum-
pers monitor the blind spots. A warning lamp appears in the door
mirror on the side in question:
- immediately, when being overtaken,
- after a delay of about one second,
when overtaking a vehicle slowly.

No alert will be given in the following
situations:
- in the presence of stationary objects
(parked vehicles, barriers, street
lamps, road signs...),
- with vehicles moving in the opposite
direction,
- driving on a sinuous road or a sharp
corner, The alert is given by a warning lamp
which comes on in the door mirror on
the side in question as soon as a ve-
hicle - car, lorry, cycle - is detected and
the following conditions are fulfi lled:
- all the vehicles must be moving in
the same direction,
- the speed of your vehicle is between
7 and 75 mph (12 and 140 km/h),
- the difference in speed between
your vehicle and the other vehicles
must be less than 6 mph (10 km/h),
- the traffi c must be fl owing normally,
- in the case of an overtaking ma-
noeuvre, if this is prolonged and the
vehicle being overtaken remains in
the blind spot,
- you are driving on a straight or slightly
curved road,
- your vehicle is not pulling a trailer, a
caravan...
- when overtaking (or being over-
taken 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 for-
ward fi eld of vision,
- in very heavy traffi c: vehicles detect-
ed in front and behind are confused
with a lorry or a stationary object,
- when overtaking quickly.

The system may suffer tem-
porary interference in certain
weather conditions(rain, hail...).
In particular, driving on a wet sur-
face 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 ve-
hicle).
In bad or wintry weather, ensure
that the sensors are not covered
by mud, ice or snow.
Take care not to cover the warn-
ing 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.
)
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.
Operating fault
In the event of a fault, the warning lamp
in the button fl ashes then goes off.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
The system is automatically de-
activated when towing with a
towbar approved by CITROËN.
