Access
2Normal locking
► Press the locking button.
The locking, and the activation of the alarm
depending on version, is confirmed by the
lighting of the direction indicators.
Depending on version, the door mirrors fold.
An access (door or boot) that is not properly closed prevents locking of the
vehicle. However, if the vehicle is fitted with
an alarm, it will be activated after 45
seconds.
If the vehicle is unlocked but the doors or boot
are not subsequently opened,
the vehicle
will automatically lock itself again after about
30

seconds. If the vehicle is fitted with an
alarm, it will be reactivated automatically.
Deadlocking
Deadlocking renders the interior door
controls inoperative. It also disables the
central locking button.
The horn remains operational.
Never leave anyone inside the vehicle
when it is deadlocked.
►

Press the locking button.
►


Press the locking button again within 3
seconds to deadlock the vehicle (confirmed by
the temporary lighting of the direction indicators).
For the vehicles equipped with the Proximity
Keyless Entry and Start system, a double
audible signal indicates that the vehicle is not
deadlocked.
Opening / Closing the
windows
Opening the windows
► Press the unlocking button for more
than 3 seconds.
Depending on version, the windows stop when
the button is released or by pressing the button
a second time.
Closing the windows and sunroof
(depending on version)
► Press the locking button for more than
3 seconds.
Depending on version, the windows and the
sunroof stop when the button is released or by
pressing the button a second time.
Ensure that no person or object could
prevent the correct closing of the
windows and sunroof.
If, on versions with alarm, you want to
leave the windows and/or sunroof partially
open, you must first deactivate the interior
volumetric alarm protection.
For more information on the Alarm, refer to
the corresponding section.
Remote lighting of the
lamps
► Press this button. The sidelamps,
dipped beam headlamps, number plate
lamps and door mirror spotlamps come on for 30
seconds.
Pressing again before the end of the timed
period switches off the lamps immediately.
Advice
Remote control
The remote control is a sensitive, high-
frequency device; avoid handling it in your
pocket, due to the risk of unintentionally
unlocking the vehicle.
Avoid pressing the remote control buttons
while out of range of the vehicle, due to
the risk of rendering the remote control
inoperative. It would then be necessary to
reset it.
The remote control does not work
when the
key is in the ignition switch, even when the
ignition is switched off.
Anti-theft protection
Do not modify the electronic vehicle
immobiliser, as this might result in
malfunctions.
For vehicles with a key ignition switch,
remember to remove the key and turn the
steering wheel to engage the steering lock.

Lighting and visibility
Manual

► With the ignition off, pull the lighting control
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.

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.

172
In the event of a breakdown
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!


The headlamps have polycarbonate lenses with a protective coating:
–

Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
–


Use a sponge and soapy water or a pH
neutral product.
–


When using a high-pressure washer on
persistent marks, do not keep the lance
directed towards the headlamps, lamps or
their edges for too long, so as not to damage
their protective coating and seals.
Changing a bulb must only be done with
the ignition off and after the headlamp /
lamp has been switched off for several
minutes - risk of serious burns!
Do not touch the bulb directly with your
fingers; use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
of the same type and specification. To avoid
lighting imbalance, replace the bulbs in pairs.
Refitting the lamp units
Perform the operations in the reverse
order to dismantling.
Light-emitting diode (LED)
