  These regular maintenance operations 
will keep your vehicle in good running 
order. Ask for advice at a CITROËN dealer 
or consult the servicing booklet enclosed in 
the handbook pack.   To maintain the reliability of engines and 
emission control systems, the use of 
additives in engine oil is prohibited.  
 
Changing the brake fluid 
 
The brake fluid must be changed at 
the intervals stated, according to the 
manufacturer's servicing schedule. 
  Use fluids recommended by the 
manufacturer, which fulfil DOT4 standards. 
  The level must be between the  MIN 
 and 
  MAX 
 marks on the reservoir. 
  If fluid has to be added frequently, this 
indicates a failure which must be checked by 
a CITROËN dealer as soon as possible.     If you have to remove/refit the engine 
style cover, handle it with care to avoid 
damaging the fixing clips. 
   
Dipstick 
  There are two marks on 
the dipstick: 
   
Oil change
 
It is imperative that this is carried out at the 
intervals specified and the viscosity grade of 
the oil selected must fulfil the requirements 
in accordance with the manufacturer's 
servicing schedule. Ask for advice at at 
CITROËN dealer. 
  Remove the dipstick before filling. 
  Check the level after filling (never exceed 
the maximum mark). 
  Screw the cap back onto the sump before 
closing the bonnet.  
 
 Viscosity selection 
 
In all cases, the oil selected must meet the 
manufacturer's requirements.  
Warning lamps 
 
 
Checking by means of the warning 
lamps on the instrument panel is 
described in chapter 2, refer to the 
"Instruments and controls" section.  
   
A 
 = maximum 
  If you fill past this mark, 
contact a CITROËN dealer. 
   
B 
 = minimum 
  Never allow the level to fall 
below this mark. 
Oil level 
  Check the level regularly and top up 
between changes. The maximum 
consumption is 0.5 litre per 600 miles 
(1 000 km). Check the level with the vehicle 
level, engine cold, using the dipstick.

Levels 
 
 
Cooling system 
 
Only use the fluid recommended by the 
manufacturer. Otherwise, you risk seriously 
damaging your engine. When the engine 
is warm, the temperature of the coolant is 
controlled by the engine fan. As this fan can 
operate with the ignition key removed and 
because the cooling system is pressurised, 
wait for at least one hour after the engine 
has stopped before carrying out any work. 
  Slacken the cap by 1/4 of a turn to release 
the pressure to prevent any risk of scalding. 
When the pressure has dropped, remove the 
cap and top up the level with coolant. 
  If fluid has to be added frequently, this 
indicates a failure which must be checked by 
a CITROËN dealer as soon as possible.  
Power steering fluid level
 
The vehicle must be parked on level ground with 
the engine cold. Unscrew the cap integrated with 
the gauge and check the level which must be 
between the  MIN 
 and  MAX 
 marks.  
 
 Used oil 
 
Avoid prolonged contact of used oil with the 
skin. 
  Brake fluid is harmful to health and very 
corrosive. 
  Do not dispose of used oil, brake fluid or 
coolant into drains or into the ground but 
into the containers dedicated to this use 
at CITROËN dealerships (France) or to an 
authorised waste disposal site.  
 
 
Topping up
 
The level must be between the  MIN 
 and 
  MAX 
 marks on the expansion bottle. If 
more than 1 litre of fluid is required to top 
up the level, have the system checked by a 
CITROËN dealer.  
Windscreen wash and headlamp washlevel
 
For best quality cleaning and to prevent 
freezing, this fluid must not be topped up or 
replaced with plain water. 
  Capacity of the reservoir: approximately 
5.5 litres.

CHECKS   
Air filter and passenger compartmentfilter 
 
A clogged passenger compartment fi lter 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.  
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 specification. 
  In order to optimise the operation of units as 
important as the braking system, 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. 
Parking brake 
  Where the parking brake travel is too great 
or there is a reduction in the performance 
of the system, the parking brake should be 
adjusted, even between services. 
  Have the system checked by a CITROËN 
dealer.  Bleeding the water contained in the Diesel filter 
 
If this warning lamp comes on, 
bleed the filter, otherwise bleed 
regularly each time the engine oil 
is changed. 
  To drain the water out, unscrew the bleed 
screw or the water in Diesel sensor, located 
at the base of the filter. Leave open 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 your battery 
checked by a CITROËN dealer.  
 
 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 system, 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, contact a 
CITROËN dealer.  
Oil filter 
 
Change the filter regularly, in accordance 
with the servicing schedule.  
   
 
 
 
 
 
The presence of this label, in particular 
with the Stop & Start system, indicates the 
use of a specific 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.

Checks  
 
Particle filter system (Diesel) 
 
An addition to the catalytic converter, this 
filter makes an active contribution to the 
preservation of air quality by the retaining 
of the unburnt pollutant particles. Black 
exhaust fumes are thus no longer emitted. 
  This filter, fitted to the exhaust system, 
accumulates particles of soot. The engine 
control unit manages the automatic 
periodic elimination of the soot particles 
(regeneration). 
  The regeneration procedure is invoked 
according to the quantity of particles 
accumulated and the driving conditions of 
the vehicle. During this phase, you may 
notice some unusual phenomena - increased 
idling speed, cooling fan running, increase in 
smoke and higher exhaust gas temperature -
which does not affect the operation of the 
vehicle or the environment.   After prolonged idling or driving at very low 
speeds, you may occasionally notice water 
vapour being emitted from the exhaust when 
accelerating. This is of no consequence 
to the running of the vehicle or to the 
environment. 
  Because of the higher exhaust gas 
temperature resulting from the normal 
operation of the particle filter, it is 
recommended that you do not park the 
vehicle over inflammable materials (grass, 
dry leaves, pine needles, ...) so as to avoid 
any risk of fire.    
Saturation / Regeneration 
   
Operating fault 
  If this alert persists, do not ignore the 
warning; it indicates that a fault has occurred 
in the exhaust / particle filter system. 
  Have it checked by a CITROËN dealer.  
    If there is risk of blockage of the 
filter, this warning lamp comes on 
in the instrument panel. 
  This alert tells you that the particle filter 
is starting to fill up (in conditions of urban 
driving of exceptionally long duration: low 
speeds, traffic jams etc.) 
  To regenerate the filter, it is advised to drive 
as soon as possible, when traffic conditions 
and the law permit, at a speed of at least 
40 mph (around 60 km/h), with an engine 
speed above 2 000 rpm for about fifteen 
minutes (until the warning lamp and/or the 
message disappears). 
  If possible, avoid switching off the engine 
before the end of regeneration of the 
filter; repeated interruptions could cause 
premature deterioration of the engine oil. It 
is not recommended to end regeneration of 
the filter with the vehicle stationary.

Fuel 
 
 
Low fuel level
 
When the fuel tank level  E  
(Empty) is reached, this warning 
lamp comes on. At this moment, 
you have  enough fuel left to 
drive approximately 30 miles (50 km) 
, 
depending on the driving conditions, the 
engine and the profile of the road. Fill up 
without delay to avoid running out of fuel.   The fuel tank must be filled  with the engine 
off.  
   
 
-   Open the fuel filler flap. 
   
-   Support the cap with one hand. 
   
-   With the other hand, insert the key, then 
turn it anticlockwise. 
   
-   Remove the cap and hook it onto the 
clip located on the inside of the flap.  
  A label affixed to the inside of the flap 
reminds you of the type of fuel to be used. 
  When filling the fuel tank, do not continue 
after the 3rd cut-off of the nozzle. This could 
cause malfunctions. 
  The capacity of the fuel tank is 
approximately  90 
 litres. 
   
 
-   After filling the fuel tank, lock the cap 
and close the flap.  
 
FUEL SYSTEM CUT-OFF
 
In the event of a serious collision, a device 
automatically cuts off the fuel supply 
  to the engine and the vehicle's electrical 
supply. 
  FILLING WITH FUEL 
 
Fuel tanks of different capacities, 
60 and 125 litres, may be fitted.    Check that there is no smell or leak of fuel 
outside the vehicle. 
  Restore the supply by pressing: 
   
 
-  
the fi rst button,   
located below the steering wheel. 
 
 
-   the second button, located in the 
battery compartment, under the front 
passenger's floor.  
   
 
In low temperatures 
  In mountainous and/or cold areas, it is 
advisable to use a "winter" type fuel suited 
to low or minus temperatures.  
     
 
 
 
 
 
With Stop & Start, never refuel with 
the system in STOP mode; you must 
switch off the ignition with the key.

The charging operation must be carried 
out in a ventilated area away from naked 
flames or any possible sources of sparks to 
eliminate the risk of explosion and fire. 
  Do not attempt to charge a frozen battery: it 
must first 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. 
  Proceed with a slow charge charge at low 
current for a maximum pf about 24 hours to 
avoid damaging the battery.
