D R I V I N G The parking assistance system
cannot, in any circumstances, re-
place the need for vigilance and
responsibility on the part of the
driver.
AUDIBLE AND VISUAL FRONT AND REAR PARKING ASSISTANCE
System consisting of four proximity
sensors, installed in the front and/or
rear bumper.
It detects any obstacle (person, ve-
hicle, tree, barrier...) located in front
of and behind the vehicle, except for
obstacles located immediately be-
low the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the start of
the manoeuvre but may no longer
be detected when the vehicle moves
nearer to it. The parking assistance is
switched
on :
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h) in forward gear.
This is accompanied by an audible
signal and/or displaying of the vehi-
cle on the multifunction screen.
The proximity information is indicated
by:
- an audible signal which be- comes more rapid as the vehicle
approaches the obstacle,
- a diagram on the multifunction screen, with blocks which move
closer to the vehicle.
The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the vehicle
and the obstacle is less than approxi-
mately thirty centimetres, the audible
signal becomes continuous and/or the
"Danger" symbol appears, depending
on the multifunction screen version. The parking assistance is
switched
off :
- when you exit reverse gear,
- when the speed is higher than 6 mph (10 km/h) in forward gear,
- when the vehicle has been station- ary for more than three seconds in
forward gear.

D R I V I N G In bad weather or in winter, ensure
that the sensors are not covered
with mud, ice or snow. When re-
verse gear is engaged, an audible
signal (long beep) indicates that
the sensors may be dirty.
When the vehicle is being driven at
a speed below approximately 6 mph
(10 km/h), certain sources of noise
(motorcycles, lorries, pneumatic
drills...) may trigger the parking as-
sistance audible signals.
Press button A again, the warn-
ing lamp switches off, the system
is reactivated.
Reactivation
Press button A , the warning lamp
comes on, the system is fully de-
activated.
The system will be deactivated au-
tomatically when a trailer is being
towed or when a bicycle carrier is
fi t t e d ( v e h i c l e fi t t e d w i t h a t o w b a r
or bicycle carrier recommended by
CITROËN). Operating fault
Deactivation
If an operating fault occurs,
this warning lamp is displayed
on the instrument panel and/
or a message appears on the
multifunction screen, accompanied by
an audible signal (short beep), when
reverse gear is engaged.
Consult a CITROËN dealer.
