Emergency braking
In the event of a failure of the main service
brake or in an exceptional situation (e.g. driver
taken ill, under instruction, etc.) a continuous
pull on the control lever will brake the vehicle.
Braking takes place while the control lever is
being pulled. It is interrupted if the control lever
is released.
The ABS and DSC systems provide stability of
the vehicle during emergency braking.
If the emergency braking malfunctions, the
message "Parking brake control faulty" will be
displayed.
If a failure of the ABS and DSC systems occurs,
signalled by the illumination of one or both
warning lamps in the instrument panel, then
stability of the vehicle is no longer guaranteed.
In this event, stability must be assured by the
driver by repeating alternate "pull-release"
actions on the control lever until the vehicle is
immobilised.The emergency braking should only be
used in an exceptional situation.
Repeat this procedure to reactivate automatic
operation.
Reactivation of automatic operation is
confirmed by the indicator lamp in the
instrument panel going off.
Deactivating automatic operation
In some situations, such as very cold weather
or towing (caravan, recovery), it may be
necessary to deactivate automatic operation of
the system.

Flashing of the dashes indicates a fault with the
cruise control.
Have it checked by a CITROËN dealer or a
qualified workshop.
Operating faultWhen the cruise control is switched on,
be careful if you maintain the pressure
on one of the programmed speed
changing buttons: this may result in a
very rapid change in the speed of your
vehicle.
Do not use the cruise control on
slippery roads or in heavy traffic.
On a steep descent, the cruise control
will not be able to prevent the vehicle
from exceeding the programmed speed.
On steep climbs or when towing, the
programmed speed may not be reached
or maintained.
The use of mats not approved by
CITROËN may inter fere with the
operation of the cruise control.
To avoid any risk of jamming of the
pedals:
-
e
nsure that the mat is secured
c o r r e c t l y,
-

n
ever fit one mat on top of another.

In the event of a fault with the dynamic cruise
control, you are alerted 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.
When the cruise control is working, take
care if making a maintained press on
one of the cruise control programmed
speed modification buttons: this can
lead to a very quick change in the
speed of your vehicle.
Do not use the dynamic cruise control
on slippery sur faces or in heavy traffic.
When descending a steep hill, the
cruise control may not be able to
prevent the vehicle from exceeding the
programmed speed.
When ascending a steep hill or when
towing, it might not be possible to attain
or maintain the programmed speed.
Operating fault
The operation of the radar, located in
the front bumper, may be disturbed by
accumulations of dirt (dust, mud, etc.)
or in certain weather conditions (snow,
ice, etc.).
The message "SYSTEM INACTIVE:
Visibility reduced" is displayed to signal
that the system has been put into
st a n dby.
Clean the front bumper regularly.
When painting or touching up the
paint on the front bumper, consult
a CITROËN dealer or a qualified
workshop. Certain types of paint could
hinder the operation of the radar.
The use of mats not approved by
CITROËN may inter fere with the
operation of the cruise control.
To avoid any risk of jamming the pedals:
-

e

nsure that mats are secured

Limits of operation
In the following cases, it is recommended
that the system be deactivated in the vehicle
configuration menu:
-
w
hen towing a trailer or caravan,
-

w
hen carrying long objects on roof bars or
a roof rack,
-

b
efore using an automatic car wash, with
the engine running,
-

b
efore placing the vehicle on a rolling road
in a workshop,
-

w
hen the vehicle is being towed, with the
engine running,
-

w
hen a "space-saver" type spare wheel is
fitted (depending on version),
-

f
ollowing impact damage to the windscreen
close to the detection camera,
-

i
f the front bumper has been damaged,
-

i
f the brake lamps are not working.Because of limits in the operation of the
system, it is possible that warnings are
not given, are given too late or seem
unjustified.
Consequently, the driver must always
remain attentive and able to react at any
time to avoid an accident. Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed:
the level 2 alert may be displayed
di r e c t l y.
Important
: the level 1 alert is never
displayed if the " Close" threshold has
been selected.
Collision Risk Alert
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, different levels of alert can be
triggered and displayed in the instrument panel.
Level 1: visual alert only, signalling
to you that the vehicle in front is very
close.
The message " Vehicle close" is
displayed.
This level of alert is based on the inter-vehicle
time between your vehicle and the vehicle in
front.
Level 2: visual and audible alert,
warning you that a collision is
imminent.
The message " Brake!" is displayed.
This level of alert is based on the time before
collision. It takes account of the vehicle
dynamics, the speed of your vehicle and the
one in front, the environmental conditions, the
operation of the vehicle (cornering, pedals
pressed, etc.) to trigger the alert at the best
moment.
Modifying the alert trigger
threshold
This threshold determines how you wish to be
warned of the presence of a vehicle moving
or stationary in front of you, or a pedestrian
present in your traffic lane.
The current threshold can be modified only via
the Driving menu in the touch screen.
You can select one of three thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.

Blind Spot Monitoring System
Activation / Deactivation
A warning lamp appears in the door mirror on
the side in question:
-
i
mmediately, when being overtaken,
-

a
fter a delay of about one second, when
overtaking a vehicle slowly.
This system warns the driver of the presence of
another vehicle in the blind spot angle of their
vehicle (areas masked from the driver's field
of vision), as soon as this presents a potential
danger. Sensors fitted in the front and rear bumpers
monitor the blind spots.
The state of the system remains in memory on
switching off the ignition.
This system is designed to improve 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 traffic, to assess the distances and relative speeds of
other vehicles and to predict their movements before deciding whether to change lane.
This system is a driving aid that cannot, in any circumstances, replace the need for
vigilance on the part of the driver. Activation and deactivation of the system is
done in the Driving
menu of the touch screen.
Select the " Driving functions " tab, then
" Blind spot sensors ".
This indicator lamp comes on in the
instrument panel.
To deactivate the system, select " Blind spot
sensors " again in the " Driving functions " tab.
The indicator lamp goes off.
The system is automatically deactivated
when towing with a towbar approved by
CITROËN.

Operating faults
In the event of a fault with the power
steering, this warning lamp flashes in
the instrument panel, accompanied
by a message.
Contact a CITROËN dealer or a qualified
workshop.
Switching off
If the lateral distance between your
vehicle and the space is too great, the
system may not be able to measure the
space.
Anything projecting beyond the envelope
of the vehicle (a ladder on the roof, for
example) is not taken into account by the
Park Assist system during a manoeuvre.
In bad weather or in winter, ensure that
the sensors are not covered by road
dirt, ice or snow.
In the event of a fault, have the system
checked by a CITROËN dealer or a
qualified workshop.
If the system is deactivated during a
manoeuvre, the drive should reactivate
it to repeat the measurement. In the event of a fault, this warning
lamp flashes for a few seconds,
accompanied by an audible signal.
If the fault occurs during the use
of the system, the warning lamp
goes

off. High pressure jet washing
When washing your vehicle, keep the
lance at least 30 cm away from the
sensors.
