Lighting and visibility
Lighting control stalk
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal surface of the glass
of the headlamps and rear lamps is normal; it
disappears after the lamps have been on for a
few minutes.
Travelling abroad
If using your vehicle in a country that
drives on the other side of the road, the
headlamps must be adjusted to avoid
dazzling on-coming drivers.
Contact a CITROËN dealer or a qualified
workshop.

for the selected period of time (e.g. leaving a car
park).
With the ignition off or the
key in the STOP position
► Within 2 minutes of switching off the engine,
turn the ignition key to the STOP position or
remove the key.
► Pull the lighting control stalk towards the
steering wheel.
This indicator lamp lights up on the
dashboard.
Each action on the lighting control stalk, pulled
towards the steering wheel, extends the
guide-me-home lighting by 30 seconds up to
approximately 3 minutes. Once this time has
elapsed, the lamps go out automatically.
Deactivate this control by holding the control
stalk pulled towards the steering wheel for more
than 2 seconds.
Automatic headlamps
System which automatically changes to main
beam according to the ambient light level and
the driving conditions, using a camera located at
the top of the windscreen.
This system is a driving aid. The driver remains responsible for
the vehicle's lighting, its correct use for the
prevailing conditions of light, visibility and
traffic, and observation of driving regulations.
Activation
► Turn the lighting control stalk ring to
this position.
► Set the function by pressing the
MODE button: select "ON" in the
"Automatic main beam" menu.
For more information on Vehicle
configuration , refer to the corresponding
section.
► Flash the headlamps (going beyond the point
of resistance) to activate the function.
Operation

48
Lighting and visibility
Once the function is activated, the system
operates as follows:
If the brightness is sufficient and/or if the traffic
conditions do not allow illumination of the main
beam headlamps:
– The dipped beam headlamps will
remain on: this indicator lamp lights up on
the instrument panel.
If the brightness is very low and the traffic
conditions allow:
– The main beam headlamps
come on automatically: these
indicator lamps light up on the instrument panel.
If the situation requires a change of headlamp
beam, the driver can take over at any time.
Flashing the headlamps again pauses the
function and the lighting system changes to
"automatic illumination of headlamps" mode.
At a speed lower than approximately 9 mph (15
km/h), the function deactivates automatically.
If the main beam headlamps are still needed,
flash the headlamps again; the main beam
headlamps then remain on fixed until the vehicle
reaches a speed of approximately 25 mph (40
km/h).
Above 25 mph (40 km/h), the function is
reactivated automatically (provided that you have
not flashed the headlamps again to turn off the
main beam headlamps during this interval).
Deactivation
► Turn the lighting control stalk ring to
the "Dipped beam" position.
The system may suffer interference or not work correctly:
– under conditions of poor visibility (falling
snow, heavy rain or thick fog, etc.),
– if the windscreen in front of the camera is
dirty, misted or obscured (by a sticker, etc.),
– if the vehicle is facing highly reflective
signs.
The system is not able to detect: – road users that do not have their own
lighting, such as pedestrians,
– vehicles whose lighting is obscured, such
as when running behind a safety barrier on a
motorway, for example,
– vehicles at the top or bottom of a steep
slope, on twisty roads, on crossroads.
Parking lamps
This system allows you to leave the lamps on
when parked; with the ignition off, and the key in
the STOP position or removed.


► Move the lighting control stalk ring to position
O, then to dipped beam headlamps or main
beam headlamps.
This indicator lamp comes on in the
dashboard.
The lamps will stay on for the duration of your
parking.
Extended lighting can significantly reduce
the vehicle's battery charge.
Headlamp beam height
adjustment
To avoid inconvenience to other road users,
the height of the halogen headlamps should be
adjusted according to the load in the vehicle.
This function can be accessed in dipped beam
and main beam headlamp positions.


Successive presses on these
controls adjust the headlamps.
An indicator lamp on the display indicates the
selected setting position (0, 1, 2, 3).
Wiper control stalk

wiping speed is adapted automatically to the
intensity of the rainfall.
Automatic wipe: 1 notch downwards. This is
confirmed by a single wipe. Must be reactivated
after each time the ignition is switched off.
In this position, it is possible to increase the
sensitivity of the rain sensor by turning the ring.
Do not cover the rain sensor, located at
the top centre of the windscreen.
When washing the vehicle, switch off the
ignition or deactivate the automatic rain
sensitive wipers.
Check that the windscreen wiper blades
will be able to operate freely when using
in freezing conditions.
Use the footboard, in the lower front panel, to
remove any accumulation of snow at the base
of the windscreen and on the blades.
You can change the wiper blades. For more information on Changing
a wiper blade , refer to the corresponding
section.
With Stop & Start, when the windscreen
wiper control is in the fast wiping
position, STOP mode is not available.
Screenwash and headlamp
washers
► Pull the wiper control towards you; the
screenwash action will be accompanied by a
timed operation of the wipers.
Depending on version, the headlamp washer
is linked to the screenwash; it is activated if the
dipped beam headlamps are on.
This fluid level should be checked regularly, particularly during winter.
For more information on Checking the levels
and, in particular, on the screenwash / headlamp
washer levels, refer to the corresponding
section.

Driving
6Effective eco-driving saves fuel; accelerate
progressively, anticipate the need to slow down
and adapt your speed to suit the situation.
Indicate changes of direction well in advance so
that you are seen by other road users.
Take care
The tyres must be inflated to at least the
pressures indicated on the label, even over-
inflated by 0.2 to 0.3 bar for long journeys.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
► check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
► deactivate the Stop & Start function,
► drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
► do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.
In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the density
of the air decreases with altitude and the
performance of the engine reduces.
New vehicle: do not pull a trailer before
having driven at least 620 miles (1,000
kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill increases the temperature
of the coolant. The maximum towable load
depends on the gradient and the exterior
temperature. The cooling capacity of the fan
does not increase with engine speed.
► Reduce speed and lower the engine speed,
so as to limit the heating-up.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the vehicle
and switch off the engine as soon as possible.

Driving
the whole manoeuvre, in particular using the
mirrors.
Radar
The operation of the radar as well as the
associated functions may be impaired through
the accumulation of dirt (mud, frost, etc.), in
certain difficult weather conditions (very heavy
rain, snow) or if the bumper is damaged.
If the front bumper is to be repainted, contact
a CITROËN dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar.
Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
relief.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors as well as
the associated functions may be disturbed
by sound interference such as that emitted
by noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
A front or rear impact to the vehicle can
upset the sensors’ settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind
spots may not be detected or may no longer
be detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30 cm away
from the radar, sensors and cameras.
Mats
The use of mats not approved by
CITROËN may interfere with the operation of
the speed limiter or cruise control.
To avoid any risk of jamming the pedals:
► ensure that the mat is secured correctly,
► never fit one mat on top of another.
Units of speed
Ensure that the units of speed displayed
on the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a CITROËN dealer
or a qualified workshop.
Speed Limit recognition
and recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .




Using the camera located at the top of the
windscreen, this system detects the following
types of signs and displays the corresponding
information on the instrument panel:
– the maximum authorised speed,
– no overtaking,
– the end of the previous limitations /
restrictions.

Speed Limit recognition
and recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .




Using the camera located at the top of the
windscreen, this system detects the following
types of signs and displays the corresponding
information on the instrument panel:
– the maximum authorised speed,
– no overtaking,
– the end of the previous limitations /
restrictions.
The system detects signs on the left-hand side
and right-hand side, high and low, as well as
overlapping signs.
The system only detects circular signs.
The units for the speed limit (mph or km/h) depend on the country you are
driving in.
This should be taken into account so that you
observe the speed limit.
For the system to operate correctly when
you change country, the units for speed in
the instrument panel must be those for the
country you are driving in.
The automatic reading of road signs is a driving aid system and does not always
display speed limits correctly.
The speed limit signs present on the road
always take priority over the display by the
system.
It is possible for the system to not display the
speed limit if it does not detect a speed limit
sign within a preset period.
The system is designed to detect signs that
conform to the Vienna Convention on road
signs.
When replacing the bulbs of the headlamps,
it is highly recommended that you fit genuine
replacement parts.
Using other bulbs could reduce system
performance.
Principles

Using the camera, located at the top of the
windscreen, this system detects and reads the
speed limit indications, overtaking prohibitions
and signs indicating the end of implementation of
the signs previously mentioned.
The sign is read by the camera and is displayed
in the instrument panel when it is passed (when
the vehicle is level with it).
Display on the touch
screen tablet then on the
instrument panel
The display of signs takes place as per the
following two phases:
– All new road signs recognised are displayed
on the touch screen tablet as a pop-up for 40
seconds.
– These signs are then displayed on the
instrument panel.
The system can display two road signs (speed
limit and no overtaking/end of no overtaking)

Practical information
A 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.
Screenwash and headlamp
washer fluid
To check the level or top up this fluid on
vehicles fitted with headlamp washers,
immobilise the vehicle and switch off the engine.
Reservoir capacity: approximately 5.5 litres.


To access the filler cap, pull the telescopic filler
neck and unclip the cap.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular on the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
