Battery Batteries contain harmful substances
such as sulphuric acid and lead. They
must be disposed of in accordance with the
law and must not, in any circumstances be
discarded with household waste.
Take used batteries to an authorised waste
disposal site.
It is advisable to disconnect the battery
if the vehicle is not to be used for a
period of more than one month. To do
this on models with Stop & Start:
- press the release button E to disconnect
connector F ,
- disconnect connector F of check sensor G .
Never remove the check sensor G from the
metallic point H , except when replacing the
battery.
The presence of this label, in particular
with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification, for
which the involvement of a CITROËN dealer
is required when replacing or disconnecting
the battery.
Failure to observe this recommendation may
cause premature wear of the battery.
After refitting the battery, the Stop &
Start system will only be active after
a continuous period of immobilisation of
the vehicle, a period which depends on the
climatic conditions and the state of charge of
the battery (up to about 8 hours). Before charging
The charging operation must be carried out in
a ventilated area away from naked fl ames or
any possible sources of sparks to eliminate the
risks of explosion and fi re.
Do not attempt to charge a frozen battery: it
must fi rst be thawed to eliminate the risks of
explosion. If the battery has frozen, before
charging it have it checked by a specialist who
will check that the internal components have
not been damaged and that the container is
not cracked, which could mean that there is a
risk of a leak of toxic and corrosive acid.
Before disconnecting
Never disconnect a terminal when the
engine is running.
Before disconnecting the battery, you must wait
for 2 minutes after switching off the ignition.
Close the windows and doors before
disconnecting the battery. After reconnecting
After every reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to allow the electronic
systems to be initialised. If difficulties are
experienced after this, contact a CITROËN
dealer.
If the battery has been disconnected
for some time, it may be necessary to
reinitialise the following functions:
- the display parameters (date, time,
language, distance and temperature
units),
- the radio stations,
- the central locking.
Some settings are cleared and must be
reprogrammed. Contact a CITROËN dealer.

QUICK HELP
Fuel
FILLING WITH FUEL
Capacity of the fuel tank: approximately
45 litres .
Low fuel level
When the minimum fuel tank level
is reached, this warning lamp
comes on. When it first comes on,
you have approximately 6
litres
of fuel remaining. Refuel without delay to
avoid running out of fuel. Refuelling must be done
with the engine off.
- Open the fuel filler flap.
- Hold the filler cap with one hand.
- With the other hand, insert the key, then turn it a third of a turn.
- Remove the fi ller cap and hang it on the hook, located on the inside of the fi ller fl ap.
FUEL CIRCUIT DEACTIVATED
In the event of a serious collision, a device
automatically cuts off the fuel supply to the
engine and the vehicle's electrical supply.
It also triggers the automatic unlocking of
the doors and switching on of the courtesy
lights. A message appears on the instrument
panel display according to version.
Turn the key to the STOP position to prevent
discharging of the battery.
Check that there is no smell or leak of fuel
outside the vehicle.
With Stop & Start, never refuel with the
system in STOP mode; you must switch
off the ignition with the key. When the fuel filler flap is open, a
safety system prevents sliding of the
side door.
A label affixed to the inside of the flap
reminds you of the type of fuel to be used.
Opening the filler cap may cause a noise
resulting from the inrush of air. This vacuum
is quite normal and results from the sealing
of the fuel system.
When filling the fuel tank, do not continue
after the 3rd cut-off of the nozzle; this could
cause malfunctions.
After filling the fuel tank, lock the filler cap
and close the flap.
