The adaptive cruise control uses only engine 
braking to slow the vehicle. Consequently the 
vehicle loses speed slowly, as when releasing 
the accelerator pedal.
The system is paused automatically:
- 
i
 f the vehicle in front slows down too much 
or too suddenly, and the driver does not 
brake,
-
 
i
 f a   vehicle comes between your vehicle and 
the vehicle in front.
The regulation range is limited to a maximum 
d ifference of 19   mph (30   km/h) between the 
cruise speed setting and the speed of the 
vehicle in front. Above this, the system goes into 
pause if the safety distance becomes too short.
Poor weather conditions (very heavy 
rain, accumulation of snow in front of the 
radar) may hinder the operation of the 
system, with the display of the operating 
fault message "SYSTEM INACTIVE: 
Reduced visibility". The function remains 
unavailable until the message disappears.
Since the radar detection range is relatively 
narrow, it is possible that the system cannot 
detect:
-
 
v
 ehicles of reduced width, such as 
motorcycles, for example, -
 
v
 ehicles not running in the middle of the 
lane,
When the adaptive cruise control is 
automatically paused, it can only be 
reactivated when safe conditions are 
restored. The message "Activation 
not possible, conditions unsuitable" 
is displayed while reactivation is not 
possible.
When the conditions allow, it is 
recommended that the function be 
reactivated by pressing button 2
 
or 3,
 
which will make the current speed of your 
vehicle the new cruise speed setting, 
rather than by pressing button 4 (on /
pause) which reactivates the cruise control 
using the old cruise speed setting, which 
may be very different from the current 
speed of your vehicle.
Operating limits
- if the system does not slow the vehicle  enough to continue to maintain a   safe 
distance, for example when descending 
a
  steep hill.
-
 v
ehicles entering a
 
 corner,
-
 
v
 ehicles changing lane at the last moment.
The cruise control does not take account of:
-
 s
tationary vehicles,
-
 
v
 ehicles driving in the opposite direction.
Malfunction
In the event of a malfunction of the adaptive 
c ruise control system, you are warned by an 
audible signal and the display of the message 
"Driving aid functions fault".
Have the system checked by a
  CITROËN 
dealer or a
  qualified workshop.

The reversing camera function may be 
supplemented with parking sensors.
The reversing camera cannot, in any circumstances, 
replace the need for vigilance on the part of the driver.
They are represented by lines marked 
"on the ground" and do not allow you to 
determine the position of tall obstacles (for 
example: other vehicles, etc.) relative to 
the vehicle.
Some distortion of the image is normal.
It is normal to have a  part of the number 
plate showing in the bottom of the screen. The blue lines 1
  represent the general direction 
of the vehicle (the gap represents the width of 
your vehicle except for the door mirrors).
The red line 2   represents a   distance of about 
30   cm beyond the edge of your vehicle's rear 
b u m p e r.
The green lines 3   represent distances of about 
one and two metres beyond the edge of your 
vehicle's rear bumper.
The turquoise blue curves 4   represent the 
maximum turning circle.
Opening the tailgate causes the display to 
disappear.
Clean the reversing camera regularly 
using a   soft, dry cloth.
High pressure jet wash
When washing your vehicle, do not direct 
the lance from less than 30   cm from the 
lens of the camera.
Depending on version, the image is displayed 
on the touch screen or the instrument panel.
The representation with overlaid lines helps the 
manoeuvre.
Vision 360
This system allows the near surroundings of 
the vehicle to be viewed in the instrument panel 
using cameras.
They are situated at the front and rear of the 
vehicle, as well as under the door mirrors.
Depending on the angle of view chosen (front 
view, rear view or 360° panoramic view), the 
Vision 360
  system provides a   specific visual aid 
in particular driving conditions, such as when 
entering a
  blind crossroads or manoeuvring in 
areas with reduced visibility.
Once activated, this function is operational up 
to 9
  mph (15   km/h). Above 19   mph (30   km/h), 
the system deactivates automatically.

This system is a visual aid that cannot in 
a ny circumstances replace the need for 
vigilance on the part of the driver.
The images provided by the camera(s) 
may be distorted by the relief. The 
presence of areas in shadow, bright 
sunlight, or poor lighting conditions may 
make the image dark and reduce contrast.
Forward vision
The camera situated on the front bumper is 
activated and the views of the area to the 
front left and the area to the front right of your 
vehicle appear simultaneously in the instrument 
panel.
Rear vision
The camera situated on the tailgate is activated 
and the view of the area behind your vehicle is 
displayed in the instrument panel and behaves 
as a
  reversing camera, regardless of the 
position of the gear selector.
The blue outline represents the width of 
your vehicle (without mirrors): its orientation 
depends on the position of the steering wheel.
The red line represents the distance of 30 cm) 
from the rear bumper and the two green lines 
the distances  of 1 m and 2 m respectively from 
the rear bumper.
The rear vision is displayed automatically 
when reverse gear is engaged, regardless 
of the state of the system.
Vision 360
The cameras situated on the front and rear 
bumpers as well as those below the door 
mirrors activate and a   view from above of your 
vehicle in its close environment is generated 
and is displayed in the instrument panel.
Opening a door or the tailgate will disrupt the 
3 60   and rear views.
Installation of the very cold climate screen will 
alter the image transmitted by the front camera.

Putting the spare wheel back in 
placeSince the width of the spare wheel is 
smaller than the width of the wheels of 
the vehicle, in the event of a  puncture, the 
punctured wheel must be stored in the boot.

Access to tooling
(Depending on version. The full set of tools is 
supplied with the spare wheel.) The rest of the tools, the jack 3
  and the wheel 
bolt cover removal tool 4 , are stored in a   box 
attached to the spare wheel.
The assembly is secured under the vehicle by 
means of a
  winch carrier system.
Procedure for changing a
  wheel with 
a   damaged or punctured tyre for the spare 
wheel using the tools provided with the vehicle. One part of the tools can be accessed from the 
boot.
The immobilisation chock 2   as well as the 
wheelbrace extension 6   are stored in the right-
hand section of the boot sill trim.
The wheelbrace 1   and the towing eye 7   are 
stored in the left-hand section of the boot sill 
trim.
