Par ticle emission filter (Diesel)
On a new vehicle, the first operations of regeneration of the par ticle emissions filter may be accompanied by the smell of "burning", w hic h is per fec t ly normal.Following prolonged operation of the vehicle at very low speed or at idle,you may, in exceptional circumstances,notice the emission of water vapour at the exhaust on acceleration. This doesnot affect the behaviour of the vehicleor the environment.
Manual gearbox

The gearbox does not require anymaintenance (no oil change).
Refer to the ser vicing booklet for the
details of the level checking interval for this component.
According to your version of instrument panel, the start of
saturation of the par ticle emissions filter is indicated by:

As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 40 mph (60 km/h) until the warning lamp goes off.
If the warning lamp stays on, refer to the
"Additive level" section.

)Switch on the compressor by movingthe switch Bto position "I" until the tyre pressure reaches 2.0 bars.
The sealant is injected into the tyre under
pressure; do not disconnect the pipe from
the valve during this operation (risk of
splashing).
)Remove the kit and screw the cap back on
the white pipe.
Take care to avoid staining your vehicle
with traces o
f fluid. Keep the kit to hand.
)Drive immediately for approximately three miles (five kilometres), at reduced speed (between 15 and 35 mph (20 and 60 km/h)),
to plug the puncture.)Stop to check the repair and the tyre pressure using the kit.
Do not star t the compressor beforeconnecting the white pipe to the tyrevalve: the sealant product would beexpelled through the pipe.
Tyre under-infl ation detection
If the vehicle is fitted with tyre under-inflation detection, the under-inflationwarning lamp will remain on after the wheel has been repaired until the system is reinitialised by a CITROËN dealer or a qualified workshop.

273Practical information

Charging the battery using
a battery charger

If the battery of your vehicle is flat or prior
to taking the vehicle out of ser vice for an extended period, you can charge the battery
using a battery charger.
For information on the specification of batterychargers compatible with your battery, refer to
a CITROËN dealer or a qualified workshop.

The Stop & Start battery does not haveto be disconnected for charging.


Reinitialisation after
reconnection
After any reconnection of the battery, switch on
the ignition and wait at least one minute before
starting, to allow time for the initialisation of theelectronic systems.
By referring to the corresponding sections, you should set or initialise the following systems yourself:


- one-touch electric windows,

- time and date,

- audio and navigation system settings.

It is recommended that the battery be disconnected if the vehicle is not be used for more than a month.

Check that no aler t message or warning lamp comes on after switching on the ignition.
However, if minor problems persist after carrying out these operations, contact a CITROËN dealer or a qualified workshop.



Before disconnecting
)Go to the battery. )Check that all of the openings - doors, boot... - are closed but not locked.)Wait at least four minutes after switchingoff the ignition.
Charging
)
Disconnect the (+)terminal. )
Follow the instructions on use provided by
the manufacturer of the charger.) Connect the red cable of the charger to the (+) post of the battery, then the black cable
to the (-) terminal.) Once charging is complete, disconnect thecharger cables in reverse order.
The charging operation must be carried outin a well ventilated area and well away from naked flames and sources of sparks, so as to avoid any risk of explosion and fire. Do not try to charge a frozen battery; the
battery must first be thawed out to avoid any risk of explosion. If the battery hasfrozen, before charging, have it checkedby a CITROËN dealer or a qualified workshop, who will ensure that the internal components have not been damaged and that the casing is not cracked, which wouldintroduce the risk of a leak of toxic and corrosive acid.
