Lighting and visibility
This is confirmed by an audible signal and
illumination of the corresponding direction
indicator lamp in the instrument panel.
To switch off the parking lamps, return the
lighting control stalk to the central position.
Automatic illumination of headlamps
When the ring is at the “AUTO" position and
a low level of ambient light is detected by the
rain/sunshine sensor, the number plate lamps,
sidelamps and dipped beam headlamps are
switched on automatically, without any action on
the part of the driver. They may also come on if
rain is detected, at the same time as automatic
operation of the windscreen wipers.
As soon as the brightness returns to a sufficient
level or after the windscreen wipers are switched
off, the lamps are switched off automatically.
Malfunction
In the event of a malfunction of the
sunshine sensor, the lighting comes on
and this warning lamp is displayed in the
instrument panel, accompanied by an audible
signal and/or a message.
Contact a CITROËN dealer or a qualified
workshop.
Do not cover the sunshine sensor, linked
with the rain sensor and located at the
top centre of the windscreen behind the
If the driver's door is opened, a temporary
audible signal warns the driver that the lamps
are on.
They will go off automatically after a period
of time that depends on the level of charge in
the battery (entering energy economy mode).
Switching off of the lamps when the
ignition is switched off
When the ignition is switched off, all of the
lamps turn off immediately, except for dipped
beam headlamps if automatic guide-me-home
lighting is activated.
In some weather conditions (e.g. low
temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
Never look too closely at the light beam
of LED technology lamps - risk of serious
eye injury!


Travelling abroad
Vehicles equipped with manual
headlamp beam height adjustment:
If planning to use your vehicle in a country
that drives on the other side of the road, the
dipped beam headlamps must be adjusted to
avoid dazzling oncoming drivers. Contact a
CITROËN dealer or a qualified workshop.

automatically to preserve the remaining battery
charge.
Switching off the engine leads to a loss
of braking assistance.
Starting the engine
Parking brake applied:
► With a manual gearbox, place the gear lever
in neutral then depress the clutch pedal fully.
► With an automatic gearbox, place the gear
selector in mode N or P then depress the brake
pedal fully.
► Insert the key into the ignition switch; the
system recognises the code.
► Unlock the steering column by simultaneously
turning the steering wheel and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
► With a petrol engine , operate the starter
motor by turning the key to position 3 without
pressing the accelerator pedal, until the engine
starts. Once the engine starts, release the key.
With petrol engines , after a cold start,
pre-heating the catalytic converter can
cause clearly-felt engine vibrations when
stationary, with the engine running, for
anything up to two minutes (accelerated idle
speed).
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 causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
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.
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys include an electronic engine
immobiliser system, which secret code must be
recognised in order for starting to be possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact the CITROËN dealer.
Starting / Switching off the

Speed Limit Recognition
and Recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids.


This system displays the maximum authorised
speed in the instrument panel, according to
the speed limits in the country in which you are
driving, using:
– Speed limit signs detected by the camera.
– Speed limit details from the navigation system
mapping.
Navigation mapping should be regularly
updated in order to receive accurate
speed limit information from the system.
– Signs indicating an intersection area detected
by the camera.
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
terrain.
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
any associated functions, may be disrupted
by noise pollution 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
in 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.
