Practical information
For a full charge, follow the desired charging
procedure without pausing it, until it ends
automatically. Charging can be either immediate
or deferred (except fast public charger, mode 4).
You can stop domestic or accelerated charging
at any time by unlocking the vehicle and
removing the nozzle. For superfast charging,
refer to the fast public charger.
For more information on the charging displays
on the Instrument panel and the Touch screen,
refer to the corresponding section.
It is also possible to monitor the charging
progress using the MyCitroën App
application.
For more information on Remote functions,
refer to the corresponding section.
As a safety measure, the engine will not start if the charging cable is plugged into
the connector on the vehicle. A warning is
displayed on the instrument panel.
Cooling the traction battery
The cooling fan in the engine
compartment comes on during charging to
cool the on-board charger and the traction
battery.
Low load / Driving
Driving when the charge level of the
traction battery is too low can lead to the
vehicle breaking down and can lead to
accidents or serious injuries. ALWAYS make
sure the traction battery has a sufficient
charge level.
Low load / Parking
If the outside temperature is negative,
it is recommended not to park your vehicle
outside for several hours at a low load (less
than 20%).
Vehicle in storage for more than
1 month
In the event of a long period of non-use of
the vehicle (beyond 4
weeks) without the
possibility of charging when restarting, the
self-discharge may make it impossible to
restart if the traction battery charge level
is a low or very low, especially at negative
ambient temperatures. ALWAYS make sure
that the traction battery has a charge between
20% and 40% if you do not plan to use your
vehicle for several weeks.
Do not connect the charging cable.
Always park the vehicle in a place with
temperatures between -10°C and 30°C
(parking in a place with extreme temperatures
can damage the traction battery).
Disconnect the cable from the (+) terminal
of the accessory battery in the engine
compartment.
Connect a 12 V battery charger to the (+)
and (-) terminals of the accessory battery
about every 3 months in order to recharge the
accessory battery and maintain an operating
voltage.
Precautions
Our electric vehicles have been developed in
accordance with the recommendations on the
maximum limits for electromagnetic fields, as
issued by the International Commission on Non-
Ionizing Radiation Protection
(ICNIRP - 1998
Guidelines).
Wearers of pacemakers or equivalent
devices
Ask your doctor about what precautions you should take, or ask the manufacturer
of your implanted electro-medical device about
whether its operation is guaranteed in an
environment which complies with the ICNIRP
recommendations.
If in doubt
Domestic or accelerated charging: do
not remain inside or near the vehicle, or near
the charging cable or charging unit, even for
a short time.
Superfast charging: do not use the system
yourself and avoid approaching public fast
charging points. Leave the area and ask a
third party to recharge the vehicle.

Towing device
Load distribution
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle, and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus reducing
engine performance.
The maximum towable load
must be reduced by 10% per 1,000
metres of
altitude.
Use genuine towing devices and wiring
harnesses approved by CITROËN. We
recommend having them fitted by a CITROËN
dealer or a qualified workshop.
If not fitted by a CITROËN dealer, they must
still be fitted in accordance with the vehicle
manufacturer's instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated while an
approved towing system is in use.
For more information about driving with a
towing device fitted to a trailer and associated
with the Trailer stability assist, refer to the
corresponding section.
Comply with the maximum authorised
towable weight, as indicated on your
vehicle's registration certificate, on the
manufacturer's label and in the Technical
data section of this guide.
If using accessories attached to the
towing device (e.g. bicycle carriers, tow
boxes):
–

Comply with the maximum authorised nose
weight.
–


Do not transport more than 3 bicycles.
When loading bicycles on to a bicycle carrier
over the towball, be sure to place the heaviest
bicycles as close as possible to the vehicle.
Observe the legislation in force in the
country where you are driving.

153
Practical information
7Drive gently: the vehicle will be more
susceptible to the effects of side winds and its
stability may be affected.
Regularly check the security and tight
fastening of the roof bars, at least before each
trip.
Remove the roof bars once they are no longer
needed.
Sunroof
Check that the load does not pass below
the roof bars so that it does not impede the
movements of the sunroof - risk of major
damage!
Direct fitting on roof

The transverse bars must only be fixed at the
four anchorage points located on the roof frame.
These points are concealed by the vehicle doors
when the doors are closed.
The roof bar fixings have a stud which must be
inserted into the opening of each anchorage
point.
Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the vehicle
when braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Observe the legislation in force in your
country relating to the use of snow
chains and maximum authorised speeds.
Use only chains designed to be fitted to the type
of wheel fitted to the vehicle:
Original tyre size Chain type 215/65 R16 Polaire XP9 120 (9
mm)
215/60 R17 Polaire XP9 120 (9
mm)
195/60 R18 Polaire PSS 112 (10
mm)
For more information on snow chains, contact a
dealer or a qualified workshop.
Installation tips
► To fit the snow chains during a journey, stop
the vehicle on a flat surface at the side of the
road.
►

Apply the parking brake and position any
wheel chocks under the wheels to prevent
movement of the vehicle.
►


Fit the snow chains following the instructions
provided by the manufacturer

.
►

Move off gently and drive for a few moments,
without exceeding 31

mph (50 km/h).
►

Stop the vehicle and check that the snow
chains are correctly tightened.
It is strongly recommended that you
practise fitting the snow chains on a level
and dry surface before setting off.
Avoid driving with snow chains on roads that have been cleared of snow to avoid
damaging the vehicle's tyres and the road
surface. If the vehicle is fitted with alloy
wheels, check that no part of the chain or its
fixings is in contact with the wheel rim.
Energy economy mode
