Topping up
The reser voir must be topped up without delay by a CITROËN dealer or a qualified workshop.
Used products
Avoid prolonged contact of used oil or fluids with the skin. Most of these fluids are harmful to health or indeed very corrosive.
Do not discard used oil or fluids into sewers or onto the ground. Take used oil to a CITROËN dealer or a qualified workshop (France) or to an authorised waste disposal site.
 Open the bonnet and secure it with the stay.  Open the screenwash reser voir filler cap.  Take and pinch the level gauge to block its breather.  Remove the gauge completely from the reser voir to read the level in the transparent section.  Top up if necessary.  Refit the filler cap to the reser voir and close the bonnet.
Specifi cation of the fl uid
To ensure optimum cleaning and to avoid freezing, the fluid should never be topped up or replaced by plain water.
According to your version of instrument panel, the additive reser voir low level is indicated by:
- fixed illumination of the particle emissions filter warning lamp, accompanied by an audible signal and a message that the particle emissions filter additive level is too low,
or
- fixed illumination of the ser vice warning lamp, accompanied by
an audible signal and a message that the par ticle emissions filter additive level is too low.

263Practical information
Battery
Procedure for charging your battery when it is flat or for star ting the engine using another battery.
The battery is located under the bonnet. To gain access to it:  open the bonnet using the interior release lever, then the exterior safety catch,  secure the bonnet stay,
 remove the plastic cover to gain access to the two terminals,  unclip the fusebox to remove the battery, if necessary.
Access to the battery
 Raise the locking tab fully.
Disconnecting the cables
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).
The presence of this label, in par ticular with the Stop & Star t system, indicates the use of a 12 V lead-acid battery with special technology and specification; the involvement of a CITROËN dealer or a qualified workshop is essential when replacing or disconnecting the battery. Failure to obser ve this recommendation
may cause premature wear of the battery.
Reconnecting the cables
 Position the open clip 1 of the cable on the positive terminal (+) of the battery.  Press ver tically on the clip 1 to position it correctly against the battery.  Lock the clip by lowering the tab 2 .
Do not force the tab as locking will not be possible if the clip is not positioned correctly; star t the procedure again.
