  CHECKS 
  
Bleeding the water contained in the  
diesel filter   
 If this warning light comes on, 
bleed the filter, otherwise bleed 
regularly each time the engine is 
drained.   
 To evacuate the water, unscrew the bleed 
screw or the water in diesel sensor, located 
at the base of the filter. Operate until all 
of the water has been drained out. Then 
tighten the bleed screw or the water sensor.  
 HDi engines use advanced technology. All 
work requires a special qualification which is 
guaranteed by a  CITROËN dealer .  
  
Battery   
 At the start of winter,  have it checked by a  
CITROËN dealer .

 A clogged passenger compartment filter 
may reduce the performance of the 
air conditioning system and generate 
undesirable odours. The replacement 
intervals for these components are indicated 
in the servicing booklet. 
 Depending on the environment (dusty 
atmosphere...) and the use of the vehicle 
(urban driving...), change them twice as 
often if necessary, refer to the "Under the 
bonnet" section of chapter 7.  
  
Brake pads   
 Brake pad wear depends on the style of  
driving, in particular for vehicles which are 
used in town, over short distances. It may 
be necessary to check the thickness of the 
pads, even between services. 
 Unless there is a leak on the circuit, a drop 
in the brake fluid level indicates that the 
brake pads are worn.  
  
Brake disc/drum wear status   
 For any information relating to checking  
the brake disc/drum wear status,  consult a 
CITROËN dealer .    
Handbrake   
 Where the handbrake travel is too great 
or there is a reduction in the performance 
of the system, the handbrake should be 
adjusted, even between services. 
  Have it checked by a CITROËN dealer .  
  
Oil filter   
 Change the filter regularly, in accordance  
with the servicing schedule.  
  Manual gearbox 
 Have the level checked in accordance with  
the manufacturer ’s servicing schedule.  
 To check the main levels and certain 
components, in accordance with the 
manufacturer ’s servicing schedule, refer 
to the pages of the servicing booklet which 
correspond to your vehicle’s engine. 
 Only use products recommended by 
 CITROËN  or products of equivalent quality 
and characteristics. 
 In order to optimise the operation of units as 
important as the braking circuit,  CITROËN  
selects and offers specific products. 
 In order to avoid damaging the electrical 
units, high pressure washing to clean the 
engine compartment is strictly prohibited.
