stalk toward you ("headlamp flash") to activate/
deactivate the function.
Manual guide-me-home lighting goes off
automatically after a period of time.
Welcome lighting
When the vehicle is unlocked, if the ambient
light is low and the "Automatic illumination of
headlamps" function is activated, this system
automatically turns on certain exterior lamps
as well as certain lamps in the passenger
compartment.
You can activate/deactivate this function and adjust the welcome lighting duration
in the Driving
/ Vehicle touch screen tablet
menu.
Door mirror spotlamps
These spotlamps facilitate access to the vehicle
by lighting the ground near the front doors.
When the front courtesy lamp switch is in
this position, the spotlamps come on
automatically:
– when the vehicle is unlocked.
– when a door is opened.
–

when a request to locate the vehicle is
received from the remote control.
Whatever the position of the front courtesy lamp
switch, they also come on with the welcome
lighting and guide-me-home lighting functions.
They go off automatically after 30 seconds.
Automatic lighting systems - General
recommendations
The automatic lighting systems use a detection
camera, located at the top of the windscreen.
Operating limits
The system may be disrupted or not work
correctly:
–

When visibility conditions are poor
(e.g.

snowfall, heavy rain).
–

If the windscreen is dirty
, misted-up or
masked (e.g.
sticker) in front of the camera.
–

If the vehicle is facing highly reflective signs
or safety barrier reflectors.
The system is not able to detect:
–


Road users that do not have their own
lighting, such as pedestrians.
–


V

ehicles with hidden lighting (e.g. travelling
behind a safety barrier on the motorway).
–

V

ehicles at the top or bottom of a steep
slope, on winding roads, on crossroads.
Maintenance
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal surface of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
obstruct the camera.
Automatic headlamp dipping
For more information, refer to the
General recommendations for
automatic lighting systems.
With the ring of the lighting control stalk
in the
"AUTO" position and the function activated on
the touch screen, this system automatically
switches between dipped and main beam
headlamps, according to lighting and traffic
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 in the
prevailing light, visibility and traffic conditions,
and for compliance with driving and vehicle
regulations.
The system becomes operational when the vehicle exceeds 16 mph (25 km/h).
When the speed falls below 9 mph (15 km/h),
the function is no longer operational.
Activation/Deactivation
It is set via the Driving / Vehicle touch
screen menu. The state of the system stays in the memory
when switching off the ignition.
Operation
If the ambient light level is very low and traffic
conditions permit:
– The main beam headla
mps
come on automatically. These
indicator lamps light up on the instrument panel.
If the ambient light level is sufficient and/or the
traffic conditions do not allow the main beam
headlamps to be lit:
– The dipped beam head lamps
remain lit. These indicator lamps
light up on the instrument panel.
The function is deactivated if the foglamps
are switched on or if the system detects poor
visibility conditions (e.g.
fog, heavy rain,
snowfall).
When the foglamps are switched off or when the
visibility conditions become favourable again, the
function is automatically reactivated.
This indicator lamp goes out when the function is deactivated.
Pause
If the situation requires a change of headlamp
beam, the driver can take over at any time.
►

Switch the headlamps manually between
dipped and main beam to pause the function.
If the "AUT

O" and "Dipped beam" indicator
lamps were on, the system changes to main
beam. If the "AUTO" and "Main beam" indicator
lamps
were on, the system changes to dipped beam.
►
T
o reactivate the function, once again switch
the headlamps manually between dipped and
main beam.
Malfunction
If a malfunction occurs with the system or
the camera, this warning lamp lights up
on the instrument panel, accompanied by an
audible signal and a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
Cornering lighting
This system makes use of the beam from a front
foglamp to illuminate the inside of a bend, when
the main or dipped beam headlamps are on and
the vehicle speed is below 25 mph (40
km/h)
(urban driving, winding road, junctions, parking
manoeuvres).

Driving
6Noise (Electric)
On the outside
Due to the vehicle’s quiet operation when
driving, the driver must pay particular attention.
When manoeuvring, the driver must always
check the vehicle's immediate surroundings.
At speeds of up to 19 mph (30 km/h), the
pedestrian horn warns other road users of the
vehicle’s presence.
Cooling the traction battery
The cooling fan comes on during
charging to cool the on-board charger and the
traction battery.
On the inside
During use, you may hear certain perfectly
normal noises specific to electric vehicles, such
as:
–

T
raction battery relay when starting.
–

V
acuum pump when braking.
–

V
ehicle tyres or aerodynamics when driving.
–

Jolting and knocking noise during hill starts.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has 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 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.
►


Pay constant 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
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.

Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climatic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
monitor traffic conditions, assess the distance
and relative speed of other vehicles, and
anticipate their manoeuvres before using the
direction indicator and changing lanes.
These systems do not make it possible to
exceed the laws of physics.
Driving aids
You should hold the steering wheel with
both hands, always use the door and interior
mirrors, always leave your feet close to the
pedals and take a break every 2 hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the
mirrors.
Radar(s)
The operation of the radar(s), along with
any associated functions, may be affected
by the accumulation of dirt (e.g.
mud, ice),
in poor weather conditions (e.g.
heavy rain,
snow), or if the bumpers are 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(s).


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 front of you.


– When a vehicle cuts in sharply between your
vehicle and the one in front.
Some vehicles on the road may be
poorly perceived or interpreted by the
camera and/or the radar (e.g.
truck), which
can lead to an incorrect evaluation of
distances and result in inappropriate
acceleration or braking of the vehicle.
Pay particular attention:
– When motorcycles are present and
when there are vehicles staggered across the
traffic lane.
–

When entering a tunnel or crossing a
bridge.
If any of the following malfunctions
occurs, do not use the system:

a message and an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
Active lane departure warning system
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The system corrects the vehicle's trajectory by
alerting the driver as soon as it detects a risk of
involuntary
lane departure or crossing of a verge
or hard shoulder (depending on version).
To do this, the system uses a camera, placed on
the upper part of the windscreen, identifying the
lane markings on the ground and the side of the
road (depending on version).
This system is particularly useful on
motorways and main roads.


Operating conditions
– Vehicle speed between 40 and 112 mph (65
and 180 km/h).
–

Road marked with a central dividing line.
–


Steering wheel held in both hands.
–


Direction indicators not activated.
–


ESC system activated and operational.
The system helps the driver only if there is a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or braking.
The driver must hold the steering wheel with
both hands in a way that allows control to
be maintained in circumstances where the
system is not able to intervene (for example, if
the central dividing line disappears).
Operation
As soon as the system identifies a risk of
involuntarily crossing one of the lane markings
