EASE OF USE and COMFORT



Ventilation



DEMISTING AND DEFROSTING


Windscreen
The vents 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 eight vents.
The manual air conditioning includes a
pollen filter and air recirculation.
The pollen filter permits continuous and
effective filtering of dust.
Air recirculation (which can be operated by
the driver or the passenger) isolates the
passenger compartment from the exterior
atmosphere. However, this position should
only be used temporarily, you should
normally drive with the control in the exterior
air intake position.
Manual mode
Turn the control to this air
distribution setting.
For faster and more effective
demisting and defrosting of the
windscreen:


- increase the air flow setting,
Return to the exterior air intake
position as soon as possible to
allow renewal of the air in the
passenger compartment.
Rear screen and mirrors defrosting
This function only operates when
the engine is running. Pressing
this button activates the rapid
demisting/defrosting of the rear
screen and mirrors. This function switches
off automatically to prevent an excessive
consumption of energy. It switches off when
the engine is switched off. Pressing this
button switches the function off.


- move the exterior air intake
control temporarily to air
recirculation.

Ventilation


CORRECT USE OF THE AIR
CONDITIONING
Operate the air conditioning system for
5 to 10 minutes, once or twice a month,
to keep it in perfect 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 or
a qualified workshop.
VENTS

For optimum distribution and diffusion of hot
or cool air in the passenger compartment,
there are:


- 2 adjustable central vents,

- 2 adjustable and closing side vents,

- 2 vents directed towards the floor of the
vehicle.
In order to be effective, the air conditioning
should only be used with the windows
closed. However, if the interior temperature
is 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.

Checks


CHECKS


Bleeding water from the Diesel filter

If this warning lamp comes
on, you must bleed the filter;
otherwise bleed the filter
regularly, every time the engine
oil is changed.
To remove 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 flowed out. Then tighten the
bleed screw or the water sensor.
HDi engines use advanced technology. All
work requires specialist knowledge, which
all CITROËN dealers have.


Battery

At the start of winter, have your battery
checked by a CITROËN dealer or a qualified
workshop.


Air filter and passenger compartment filter

A blocked 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 maintenance and warranty guide.
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 type of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the brake pad wear,
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

For all information on checking the brake
disc / drum wear, contact a CITROËN dealer
or a qualified workshop.


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 or a qualified workshop.


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







Manual gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the maintenance and warranty
guide for the details of the level checking
interval for this component.
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule,
refer to the pages of the maintenance and
warranty guide 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.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes.






Particle filter system (1.3 HDi 75)

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.
Saturation/Regeneration
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.

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 or a
qualified workshop.








Electronic gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the maintenance and warranty
guide for details of the checking interval for
this component.
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.
