2011 Citroen DS3 air filter

23

Limit the causes of excess
consumption

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.

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 par ticular:


- 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 ser viced regularly (engine
oil, oil filter, air filter...) and obser ve 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 over flow.

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.

Switch off the headlamps and front foglamps
when the level of light does not require their
use.

Avoid running the engine before moving off,
particularly in winter; your vehicle will warm
up much faster while driving.

As a passenger, if you avoid connecting
your multimedia devices (film, music, video
game...), you will contribute towards limiting
the consumption of electrical energy, and so
of fuel.
Disconnect your portable devices before
leaving the vehicle.

Vent ilat ion


Air intake

The air circulating in the passenger compar tment
is filtered and originates either from the outside
via the grille located at the base of the windscreen
or from the inside in air recirculation mode.


Air treatment

The incoming air follows various routes
depending on the controls selected by
the driver:


- direct arrival in the passenger compartment
(air int ake),

- passage through a heating circuit (heating),

- passage through a cooling circuit (air
conditioning).
The temperature control enables you to obtain
the level of comfor t required by mixing the air of
the various circuits.
The air distribution control enables you to
diffuse the air in the passenger compar tment
combining several air vents.
The air flow control enables you to increase or
reduce the speed of the ventilation blower.


Control panel

The controls of this system are grouped
together on control panel A
on the centre
console. Depending on the model, the functions
offered are:


- the level of comfor t required,

- air flow,

- air distribution,

- demisting-defrosting,

- manual or digital air conditioning controls.

Recommendations for ventilation and air conditioning


If after an extended stop in sunshine,
the interior temperature is very
high, first ventilate the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
The air conditioning system does not
contain chlorine and does not present
any danger to the ozone layer. In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:


)
To obtain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as the air extractor located in the boot.

)
Do not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the digital air conditioning system.

)
Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in per fect working order.

)
Ensure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly (refer to the "Checks" section).
We recommend the use of a combined passenger compartment filter. Thanks to its
special active additive, it contributes to the purification of the air breathed by the
occupants and the cleanliness of the passenger compartment (reduction of allergic
symptoms, bad odours and greasy deposits).

)
To ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly as recommended in the Maintenance and Warranty Guide.

)
If the system does not produce cold air, switch it off and contact a CITROËN dealer or a
qualified workshop.
When towing the maximum load on a steep gradient in high temperatures, switching off the
air conditioning increases the available engine power and so improves the towing ability.
The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.

Unless other wise indicated, check these components in accordance with the Warranty and Maintenance Record and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
The battery does not require any
maintenance.
However, check that the terminals
are clean and correctly tightened,
particularly in summer and winter.
When carrying out work on the battery, refer to
the "Practical information" section for details of
the precautions to be taken before disconnecting
the battery and following its reconnection.


Refer to the Warranty and
Maintenance Record for details of
the replacement inter vals for these
components.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace them twice as often if
necessary
(refer to the "Engines" section).
A clogged passenger compar tment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.


Replace the oil filter each time the
engine oil is changed.
Refer to the Warranty and
Maintenance Record for details of
the replacement inter val for this
component.





The presence of this label, in particular with
the Stop & Star t system, indicates the use of
a specific 12 V lead-acid battery with special
technology and specification, for which the
involvement of a CITROËN dealer or a qualified
workshop is required when replacing or
disconnecting the battery.
Failure to obser ve this recommendation may
shor ten the life of the battery. The star t of saturation of the
par ticle filter is indicated by the
temporary illumination of this warning lamp
accompanied by a message in the multi-
function screen.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 40 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates a
low additive level.

On a new vehicle, the first par ticle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
