Driving
6Operation
The system starts automatically when moving
off.
A check of the operating conditions takes place: these two indicator
lamps come on in the instrument panel.
When these conditions are met, these two
indicator lamps go off. The system is activated.
If the operating conditions are not met, the
system is activated but is no longer effective.
This is signalled by the fixed illumination of these
two warning lamps in the instrument panel.
Operating conditions
Once engaged, the system is active only when
these operating conditions are met:
– The vehicle is moving forwards.
– No malfunction of the vehicle is detected.
– The speed of the vehicle is equal to or greater
than approximately 37 mph (60 km/h).
– The longitudinal marking of the traffic lanes is
clearly visible.
– The visibility conditions are clear.
– The trajectory is in a straight line (or in the
case of bends, they are wide).
– The field of vision is sufficiently clear (the
safety distance with the vehicle ahead is
respected).
– In the event of a lane departure, the direction
indicator corresponding to the direction (right or
left) of the departure has not been operated. –
The trajectory of the vehicle is consistent with
the road layout.
Deactivation / Reactivation



► Press this button to deactivate / reactivate the
function.
Deactivation is signalled by the illumination of
the button indicator lamp.
Upon reactivation, the two instrument panel
indicator lamps remain lit and fixed until the
speed reaches 37 mph (60 km/h).
The state of the system stays in the memory
when switching off the ignition.
Detection
If a deviation in direction is detected on
the left or the right, the indicator lamp on
the corresponding side flashes in the instrument
panel, accompanied by an audible signal.
No warning is transmitted while the direction
indicator is activated and for approximately 20
seconds after the direction indicator is switched
off.
A warning may be transmitted if a direction
marking (arrow) or non-standard marking
(graffiti) is crossed.
The detection may be impeded: – if the markings on the road are worn,
– if there is little contrast between the
markings on the road and the road surface.
The system is automatically deactivated if the Stop & Start function is active. The
system will restart and re-enable recognition
of the operating conditions after the vehicle is
started.
The system may suffer interference or not work correctly:
– when the vehicle is carrying an excessive
load (even more so if it is poorly balanced);
– under poor visibility conditions (rain, fog,
snow, etc.);
– under poor light conditions (dazzling
sunlight, darkness, etc.);
– if the windscreen is dirty or damaged near
the camera;
– if the ABS, DSC, ASR or Intelligent Traction
Control systems are out of order.
Malfunction
When a malfunction occurs, this warning
lamp lights up, accompanied by an

– Auto: for an automatic detection of the trailer
length (3 m, 6 m or 9 m).
In Auto mode, an icon appears in the instrument
panel indicating the length detected by the
system.
It may be necessary to make a 90° turn
to allow the system to detect the length
of the trailer.
When a trailer is detected, vehicle detection
when reversing is deactivated.
Operating conditions
– All vehicles are moving in the same direction
and in adjacent lanes.
– The speed of your vehicle is 6 mph (10 km/h)
minimum.
– When you overtake a vehicle, the speed
difference is less than 16 mph (25 km/h).
– When another vehicle overtakes you, the
speed difference is less than 31 mph (50 km/h).
Active Safety Brake with Collision Risk Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system:
– warns the driver that their vehicle is at risk of
collision with the vehicle in front.
– reduces the vehicle's speed to avoid a
collision or limit its severity.
This system is comprised of three functions:
– Collision Risk Alert.
– Intelligent emergency braking assistance.
– Active Safety Brake (automatic emergency
braking).


The vehicle has a camera located at the top of
the windscreen.
This system does not avoid the need for vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor the state of the traffic, observing the
driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.
This function can be set using the MODE button; select “ON” or “OFF” in the “Active
Safety Brake” menu.
For more information on Vehicle
configuration (MODE) , please refer to
the corresponding section.
Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Operating conditions and
limits
The ESC system must not be faulty.
The DSC/ASR systems must not be deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required.
In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
– towing a trailer,
– carrying long objects on roof bars or roof rack,
– with snow chains fitted,
– before using an automatic car wash, with the
engine running,
– before placing the vehicle on a rolling road in
a workshop,
– towed vehicle, engine running,
– following an impact to the windscreen close to
the detection camera.
It is automatically deactivated after
detection of a fault with the brake pedal
switch or with at least two brake lamps.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of their
vehicle and be prepared to react at any time
to avoid an accident.
Cases of non-detection by the system:
– Pedestrians, cyclists, animals, objects on the
road.
– Vehicles crossing your lane.
– Vehicles driving in the opposite direction.

road.
– Vehicles crossing your lane.
– Vehicles driving in the opposite direction.


Pay particular attention:
– When narrow vehicles (motorcycles)
are present and/or there are vehicles
staggered across the traffic lane.
– When entering a tunnel or crossing a
bridge.
When the driver must suspend the system:


– Vehicles in a tight bend.
– When approaching a roundabout.


– When a vehicle cuts in sharply between your
vehicle and the one in front.
Collision Risk Alert
It warns the driver that their vehicle is at risk of
collision with the vehicle in front.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via the vehicle configuration menu.
► Select one of the three pre-defined
thresholds:
– "Near ".
– "Normal".
– "Distant".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, several different levels
of alert may be triggered and displayed in the
instrument panel.
They take account of the vehicle dynamics, the
speed of your vehicle and the one in front, the
environmental conditions and the operation of
the vehicle (cornering, actions on the pedals,
etc.) to trigger the alert at the best moment.
Level 1 (orange): visual alert only,
signalling that the vehicle in front is very
close.

86
Driving
The message "Vehicle close" is displayed.Level 2 (red): visual and audible alert,
signalling that a collision is imminent.
The message "Brake! " is displayed.
Level 3: finally, in some cases, a haptic alert
in the form of micro-braking can be given,
confirming the risk of collision.
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 directly.
Important: the level 1 alert is never displayed
for a stationary obstacle or when the " Close"
trigger threshold has been selected.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates under the following
conditions:
– The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle is detected.
– The vehicle's speed is between 3 mph and
53 mph (5 km/h and 85 km/h) when a moving
vehicle is detected.
This warning lamp flashes (for about 10 seconds) once the function is acting
on the vehicle's brakes.
With a manual gearbox, in the event of automatic
emergency braking until the vehicle comes to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by sharply turning the
steering wheel and/or pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop, the
automatic braking is maintained for 1 to 2
seconds.
Malfunction
In the event of a system malfunction, this
warning lamp comes on on the instrument
panel, accompanied by an onscreen message
and an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a CITROËN
dealer or a qualified workshop to have the
system checked.
Audible rear parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids .


If fitted to your vehicle, the system consists of 4
proximity sensors installed in the rear bumper.
They detect any obstacle, e.g. person, vehicle,
tree, barrier, which is behind the vehicle while
manoeuvring.
Certain types of obstacle detected at the
beginning of the manoeuvre will no longer be
detected at the end of manoeuvre if they are
located in the blind spots between and under the
sensors. Examples: stake, roadworks cone or
pavement post.
The rear parking sensors may be associated
with the reversing camera.
Switching on
► Engage reverse gear with the gear lever.

Practical information
7A clogged passenger compartment filter can adversely affect air conditioning
system performance and generate
undesirable odours.
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
In addition to the catalytic converter, this filter
actively contributes to the preservation of
air quality by trapping the unburnt pollutant
particles. Black exhaust fumes are therefore not
emitted.
Operation
This filter, inserted into the exhaust system,
accumulates the carbonaceous particles. The
engine management computer automatically
and periodically manages the removal of
carbonaceous particles (regeneration).
The regeneration procedure is triggered
according to the amount of accumulated
particles and the conditions of use of the vehicle.
During this phase, you may notice certain
phenomena - accelerated idling, triggering of
the cooling fan, increased smoke and increased
temperature at the exhaust - which have no
impact on the operation of the vehicle and the
environment.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust while
accelerating. This has no impact on the
vehicle’s behaviour and the environment.
Due to the high exhaust temperatures
caused by the normal operation of the
particle filter, it is recommended not to park
the vehicle on flammable materials (grass, dry
leaves, pine needles, etc.) to avoid any risk of
fire.
Saturation/Regeneration
If there is a risk of clogging, this warning
lamp comes on, accompanied by a
message on the instrument panel display.
This warning is due to the start of saturation of
the particle filter (exceptionally long urban driving
conditions: reduced speed, traffic jams, etc.).
In order to regenerate the filter, it is
recommended to drive as soon as possible -
when traffic conditions and regulations permit
- at a speed of at least 37 mph (60 km/h), with
an engine speed above 2,000 rpm for about
15 minutes (until the warning lamp and/or the
message disappear).
If possible, avoid switching off the engine
before the end of filter regeneration; repeated
interruptions can lead to early deterioration of the
engine oil. It is not recommended to terminate
the filter regeneration with the vehicle stationary.
Malfunction
If this alert persists, do not ignore this warning;
this indicates that a malfunction has occurred in
the exhaust system/particle filter assembly.
Have the assembly checked by a CITROËN
dealer or a qualified workshop.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
Brake pads
Brake wear depends on the style of
driving, particularly in the case of vehicles
used in town, over short distances. It may be
necessary to have the condition of the brakes
checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
If this warning lamp comes on, have the
brake pads checked by a CITROËN
dealer or a qualified workshop.
After washing the vehicle, moisture, or in
wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.

In the event of a breakdown
8► Disconnect hose I and directly connect it
to the tyre valve; the cartridge will thereby be
connected to the compressor and the sealant will
not be injected.
If the tyre needs to be deflated, connect hose
I to the tyre valve and press the yellow button
located in the centre of the compressor switch.
Replacing the cartridge

To replace the sealant cartridge, proceed as
follows:
► Disconnect the hose I.
► Turn the cartridge to be replaced anti-
clockwise and lift it.
► Insert the new cartridge and turn it clockwise,
► Reconnect the hose I and connect pipe B to
its location.
The cartridge contains ethylene glycol, which is harmful if swallowed and irritates
the eyes.
It must be kept out of the reach of children.
After use, do not discard the cartridge in standard waste, take it to a
CITROËN dealer or an authorised waste
disposal site.
Spare wheel
Parking
► Park the vehicle where it does not block
traffic: the ground must be level, stable and
non-slippery.
► If the road is sloping or damaged, place an
object under the wheels to act as a chock.
► With a manual gearbox, engage first gear
then switch off the ignition to block the wheels.
► Apply the parking brake and check that the
warning lamp is on in the instrument panel.
► The passengers must get out of the vehicle
and wait where they are safe.
► Put on the high visibility vest and signal that
the vehicle is immobile by using the devices
envisaged by the legislation in force in the
country where you are driving (warning triangle,
hazard warning lamps, etc.).
► Equip yourself with the tools.
Special feature with pneumatic
suspension
If fitted to the vehicle, activate the vehicle lifting
mode before lifting the vehicle with a jack.


For right-hand drive vehicles, the buttons are
located on the right of the steering wheel.
► With the ignition on, press both buttons 1 and
2 simultaneously for at least 5 seconds.
Their indicator lamps light up, and remain fixed.
► To exit this mode, press buttons 1 and 2
simultaneously for an additional 5 seconds.
Their indicator lamps go out and the system
becomes fully operational again.
This mode is automatically deactivated if you
exceed the speed by about 3 mph (5 km/h).
Once the vehicle is well secured, proceed in the
following order:
1- Getting the tools.
2- Removing the spare wheel from its
housing.
3- Positioning the jack.
4- Replacing the wheel to be repaired.
5- Storing the wheel to be repaired.
