Spread loads throughout the vehicle;
place the heaviest items in the bottom of
the boot, as close as possible to the rear
seats.
Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof
rack, bicycle carrier, trailer...). Use a roof
box in preference.
Remove roof bars and roof racks after use.


Limit the causes of excess
consumption


At the end of winter, remove snow tyres
and refit your summer tyres.

Observe the recommendations on maintenance


Check the tyre pressures regularly, when
cold, referring to the label in the door
aperture, driver's side.
Carry out this check in particular:


- before a long journey,

- at each change of season,

- after a long period out of use.
Don't forget the spare wheel and the tyres
on any trailer or caravan.

Have your vehicle serviced regularly (engine
oil, oil filter, air filter...) and observe the
schedule of operations recommended by the
manufacturer.


When refuelling, do not continue after
the 3 rd cut-off of the nozzle to avoid any
overflow.

At the wheel of your new vehicle,
it is only after the first 1 800 miles
(3 000 kilometres) that you will see the fuel
consumption settle down to a consistent
average.

LEVELS
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.

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.

Quality of the fuel used for Diesel engines

The Diesel engines are perfectly compatible with biofuels which conform to current and future European standards (Diesel fuel which
complies with standard EN 590 mixed with a biofuel which complies with standard EN 14214) available at the pumps (containing up to 7 %
Fatty Acid Methyl Ester).
The B30 biofuel can be used in certain Diesel engines; however, this use is subject to strict application of the special servicing conditions.
Consult a CITROËN dealer.
The use of any other type of (bio) fuel (vegetable or animal oils, pure or diluted, domestic fuel...) is strictly prohibited (risk of damage to the
engine and fuel system).
