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.

DEMISTING AND DEFROSTING

Manual mode
Direct the control to this air
distribution setting.
For faster and more effective
demisting and defrosting of the
windscreen:
Defrosting the rear screen
and mirrors
Only operates when the engine
is running. Pressing this button
activates the rapid demisting-
defrosting of the rear screen and
door mirrors.
This function switches off automatically to
prevent excessive energy consumption. It
stops when the engine is switched off but
resumes when the engine is started again.
Pressing this button switches the function off.


- increase the air flow setting,

- move the exterior air intake
control temporarily to air
recirculation.
Returning to the exterior air
intake position permits renewal
of the air in the passenger
compartment.
Windscreen and side windows
The ventilation outlets located at the base
of the windscreen and the side vents for the
side windows increase the effectiveness
of the demisting and defrosting. Do not
obstruct these air outlets.
The pollen filter continuously and effectively
filters dust.
Air recirculation (which can be activated by
the driver or the passenger) isolates the
passenger compartment from the exterior
atmosphere. However, this position should
only be used temporarily, normal use is to
drive with the control positioned with the
exterior air intake open.

Ventilation

CORRECT USE OF THE AIR
CONDITIONING
In order to be effective, the air conditioning
should only be used with the windows
closed. However, if the interior temperature
remains high after a prolonged period
parked in the sun, first ventilate the
passenger compartment for a few minutes. For even air distribution, ensure that the
exterior air intake grille located at the base
of the windscreen is not obstructed and that
the side and central vents, the air outlets on
the floor and the air extractor at the rear are
open.
The air conditioning is useful in all seasons
as it eliminates condensation and air
humidity. Operate the air conditioning system for
5 to 10 minutes, once or twice a month,
to keep it in good working order.
Have the filter elements (air filter and
passenger compartment filter) replaced
regularly. If you drive in a dusty environment,
have them replaced twice as often.
It is normal that the condensation created by
the air conditioning system results in a flow
of water which may form a puddle under the
vehicle when parked.
If the system does not produce cold air, do
not use it and contact a CITROËN dealer.

"Leave them open"
For optimum distribution and diffusion of hot
or cool air in the passenger compartment,
there are: 4 adjustable central vents, of
which 2 can be directed sideways (right
or left) towards the top of the body and
4 side vents which can be directed towards
the passengers. The air vents directed
towards the floor of the vehicle complete the
equipment.

Checks


CHECKS
Air filter and passenger compartment filter

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.

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.
