central part of the filler flap to open it.
►

T
ake care to select the pump that delivers the
correct fuel type for your vehicle's engine (see a
reminder label on the inside of the filler flap).
►

T
urn the filler cap to the left, remove it and
place it on its support (on the filler
flap).
►

Insert the filler nozzle and push it in as far as
possible before starting to refuel (to minimise the
risk of splashing).
Do not continue after the nozzle’

s third cut-
out. Doing so may cause malfunctions.
►

Put the filler cap back in place and turn it to
the right.
►


Close the fuel filler flap.
If you have put in the wrong fuel for the
vehicle, you must have the fuel tank
drained and filled with the correct fuel before
starting the engine.
The vehicle is fitted with a catalytic converter,
which helps to reduce the level of harmful
emissions in the exhaust gases.
For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, admitting unleaded
petrol nozzles only.
Misfuel prevention (Diesel)
(Depending on country of sale.)
This mechanical device prevents filling the tank
of a Diesel vehicle with petrol.
Located in the filler neck, the misfuel prevention
device is visible when the filler cap is removed.
Operation

When a petrol filler nozzle is introduced into the
fuel filler neck of a Diesel vehicle, it comes into
contact with the flap. The system remains closed
and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
The use of a fuel jerrycan to fill the tank remains possible.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Before travelling abroad, it is advisable to
check with a CITROËN dealer if the vehicle is
suitable for the distribution equipment of the
countries visited.
Charging system
(Electric)
400 V electrical system

Practical information
7Traction battery
This battery stores the energy that powers
the electric motor and the thermal comfort
equipment in the passenger compartment. It is
discharged during use, and must therefore be
regularly recharged. There is no need to wait
for the traction battery to fall to its reserve level
before recharging.
The range of the battery may vary according
to the type of driving, the route, the use of
thermal comfort equipment and the ageing of its
components.
The lifespan of the traction battery depends on multiple factors, such as
climatic conditions, distance travelled and
how often it has been fast-charged.
To preserve the mileage of your vehicle and the durability of your traction battery,
CITROËN recommends that you:
–

Do not fully charge the battery of your
electric vehicle daily (charge the traction
battery below 80% as often as possible).
–


Do not completely discharge the battery
.
–

Do not store the vehicle for a long period
of non-use (more than 12

hours) when the
traction battery has a low or high charge level.
Prefer a charge level between 20 and 40%.
–

Limit the use of fast charging.
–


Do not expose the vehicle to temperatures
below -30°C and above +60°C for more than
24


hours.
– Avoid charging the vehicle at negative
temperatures (except if the vehicle ran more
than 20 minutes) or above +30°C.
–

Do not use the vehicle's traction battery as
a generator of energy

.
–

Do not use a generator to recharge your
vehicle's traction battery

.
In the event of damage to the traction
battery
It is strictly prohibited to work on the vehicle
yourself.
Do not touch liquids coming from the battery,
and in the event of skin contact with these
products, wash abundantly with water and
contact a doctor as soon as possible.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Disposal of the traction battery
The traction battery is designed for the life of the
vehicle if the recommendations of CITROËN are
followed.
If it becomes necessary to replace the battery,
contact the CITROËN dealer for instructions on
its disposal. Improper disposal carries the risk of
severe burns, electric shock, and damage to the

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.
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 4 conventional
bicycles or 2 electric bicycles.
When loading bicycles onto a bicycle carrier
on a towball, be sure to place the heaviest
