Changing the fl uid
Refer to the Maintenance and Warranty Guide for the inter val for this operation.
Fluid specifi cation
The brake fluid must conform to the manufacturer's recommendations and meet the DOT4 standard.
The brake fluid level should be close to the "MA X" mark. If it is not, check the brake pad wear.
The reading will only be correct if the vehicle is on level ground and the engine has been off for more than30 minutes. The check is carried out either when the ignition is switched on using the oil level indicator in the instrument panel, or using the dipstick.
When working under the bonnet, take care, as cer tain areas of the engine may be extremely hot (risk of burns).

Additive level (Diesel with
particle emissions filter)
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

Battery Air filter and passenger compartment filter
Oil filter
Unless other wise indicated, check these components in accordance with the Maintenance and Warranty Guide and according to your engine. Other wise, have them checked by a CITROËN dealer or a qualified workshop.
The battery does not require any maintenance. However, check that the terminals are clean and correctly tightened, par ticularly in summer and winter. When carrying out work on the battery, refer to the "Practical information" section for details of the precautions to be taken before disconnecting the battery and following its reconnection.
Refer to the Maintenance and Warranty Guide for details of the replacement inter vals for these components. Depending on the environment (e.g. dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessar y (refer to the "Engines" section). A clogged passenger compar tment filter may have an adverse effect on the per formance of the air conditioning system and generate undesirable odours.
Replace the oil filter each time the engine oil is changed.
Refer to the Maintenance and Warranty Guide for details of the replacement inter val for this component.
The presence of this label, in par ticular with the Stop & Star t system, indicates the use of a specific 12 V lead-acid battery with special technology and specification, for which the involvement of a CITROËN dealer or a qualified workshop is required when replacing or
disconnecting the battery. Failure to obser ve this recommendation may shor ten the life of the battery.

Take care, this product is harmful (e.g. ethylene-glycol, colophony...) if swallowed and causes irritation to the eyes. Keep it out of reach of children.

241Practical information
2. Infl ation
 Adjust the pressure using the compressor (to inflate: switch B in position "I" ; to
deflate: switch B in position "O" and press button C ), in accordance with the vehicle's tyre pressure label (located on the left hand door aper ture). A loss of pressure indicates that the puncture has not been fully plugged; contact a CITROËN dealer or qualified
workshop for assistance.  Remove and stow the kit.  Drive at reduced speed (50 mph [80 km/h] max) limiting the distance travelled to approximately 120 miles (200 km).
