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.

PARKING SPACE SENSORS
   
System which measures the parking 
space available between two vehicles 
or obstacles. It measures the size of the 
space and gives you information on: 
   
 
-   the possibility of fi tting into a free 
space, depending on the dimensions 
of your vehicle and the distances 
needed for manoeuvring, 
   
-   the level of diffi culty of the manoeuvre 
to be performed.  
  The system does not measure spaces 
which are clearly much smaller or larger 
than the size of the vehicle.   
 
Displays in the instrument panel 
 
 
 
-   on fi xed: 
 the function is selected by 
a press on control  A 
. 
   
-   off: 
 the function is not selected,  
    The parking space sensor 
function warning lamp can 
have two different states: 
Operation 
  You have identifi ed a parking space: 
   
 
 ) 
  Press button  A 
 to select the function. 
   
 ) 
  Operate the direction indicator on 
the side where the space is to be 
measured; a message is displayed 
to confi rm that measurement is in 
progress. 
   
 ) 
 During measurement, go forward 
the length of the space, at a speed 
less than 12 mph (approx. 20 km/h), 
to prepare for your manoeuvre. 
   
 ) 
  Once the measurement has been 
completed, the system informs you 
of the level of diffi culty of the ma-
noeuvre by a message in the multi-
function screen accompanied by an 
audible signal.

The function displays the following 
types of message: 
   
Parking possible 
 
   
Parking diffi cult 
 
   
Parking not advised 
 
   The function deselects itself automati-
cally: 
   
 
-   when you engage reverse gear, 
   
-   when you switch off the ignition, 
   
-   if measuring is not requested, 
   
-  within fi ve minutes of selection of 
the function, 
   
-   if the vehicle speed exceeds the 
threshold of 45 mph (approx. 70 km/h) 
for one minute.  
   
If the lateral distance between your ve-
hicle and the parking space is too large, 
the system may not be able to measure 
the space.  
  If there is a fault, have the sys-
tem checked by a CITROËN 
dealer or a qualifi ed workshop.  
     
The system remains available after 
each measurement and can therefore 
measure several spaces in succession. 
  In poor or wintry weather, ensure that 
the sensors are free of dirt, ice or 
snow. 
  The parking space sensor system de-
activates the front parking sensors 
when measuring forwards.

PARKING SENSORS 
  This system indicates the proximity of an 
obstacle (person, vehicle, tree, gate, etc.) 
which comes within the fi eld of detection 
of sensors located in the bumper. 
  Certain types of obstacle (stake, road-
works cone, etc.) detected initially will 
no longer be detected at the end of the 
manoeuvre due to the presence of blind 
spots.  
   
This function cannot, in any cir-
cumstances, take the place of 
the vigilance and responsibility 
of the driver.  
   The system is switched on by engaging 
reverse gear. This is accompanied by 
an audible signal. 
  The system is switched off when you 
exit reverse gear. 
   
Audible assistance 
  The proximity information is given by an 
intermittent audible signal, the frequency 
of which increases as the vehicle ap-
proaches the obstacle. 
  The sound emitted by the speaker (right 
or left) indicates the side on which the 
obstacle is located. 
  When the distance between the vehicle 
and the obstacle becomes less than 
approximately thirty centimetres, the 
audible signal becomes continuous.  
    
 
Visual assistance 
  This supplements the audible signal 
by displaying bars in the multifunction 
screen which move progressively near-
er to the vehicle. When the obstacle is 
near, the "Danger" symbol is also dis-
played in the screen.

  In addition to the rear parking sensors, 
the front parking sensors are triggered 
when an obstacle is detected in front 
and the speed of the vehicle is still below 
6 mph (10 km/h). 
  The sound emitted by the speaker (front 
or rear) indicates whether the obstacle 
is in front or behind. 
  The front parking sensors are interrupted 
if the vehicle stops for more than three 
seconds in forward gear, if no further ob-
stacles are detected or when the speed 
of the vehicle exceeds 6 mph (10 km/h).  
 
Front parking sensors 
 
Deactivation/Activation of the front 
and rear parking sensors 
  The function is deactivated by pressing 
this button. The indicator lamp in the 
button comes on. 
  Pressing this button again reactivates 
the function. The indicator lamp in the 
button goes off.  
 Operating fault
 
 
 
The function will be deactivated 
automatically if a trailer is being 
towed or a bicycle carrier is fi t-
ted (vehicle fi tted with a towbar 
or bicycle carrier recommended 
by CITROËN).  
    
In bad weather or in winter, en-
sure that the sensors are not 
covered with mud, ice or snow. 
When reverse gear is engaged, 
an audible signal (long beep) in-
dicates that the sensors may be 
dirty. 
  When the vehicle is moving at a 
speed below 6 mph (10 km/h), 
certain sound sources (motor-
cycle, lorry, pneumatic drill, etc.) 
may trigger the audible signals 
of the parking sensor system.  
    In the event of a malfunction 
of the system, when reverse 
gear is engaged this warn-
ing lamp is displayed in the 
instrument panel and/or a message ap-
pears in the screen, accompanied by 
an audible signal (short beep). 
  Contact a CITROËN dealer or a qualifi ed 
workshop.
