2018 CITROEN DS4 air filter

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...). Preferably, use a roof
box.
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 particular:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use. Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter...) and
obser ve the schedule of operations in the
manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. As soon as possible, visit a member
of the dealer network or a qualified workshop
to make your vehicle’s level of nitrogen oxides
emissions compliant to the standard.
When filling the tank, do not continue after the
3rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after around the first 1,900 miles (3,000
kilometres) that you will see the fuel
consumption settle down to a consistent
average. Do not forget the spare wheel and the tyres on
any trailer or caravan.

Recommendations for ventilation and air conditioning
In order for these systems to be fully
effective, follow the operation and
maintenance guidelines below:
F
T
o ensure that the air is distributed
evenly, keep the external air intake
grilles at the base of the windscreen,
the nozzles, the vents, the air outlets
and the air extractor in the boot free
from obstructions.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used
for regulation of the automatic air
conditioning system.
F

O
perate the air conditioning system for
at least 5 to 10 minutes once or twice
a month to keep it in per fect working
o r d e r.
F

E
nsure that the passenger
compartment filter is in good condition
and replace the filter elements
periodically. We recommend the use of
a combined passenger compartment
filter. Thanks to its special active
additive, it helps both to purify the air
breathed by the occupants and to keep
the passenger compartment clean
(reduction of allergic symptoms, bad
odours and greasy deposits). F
T o 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.
F

I
f the system does not produce cold air,
switch it off and contact the dealer network
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.
To avoid the windows misting up and
deterioration in the quality of the air:
do not drive for too long with the ventilation
switched off.
Do not keep air recirculation set for an
extended period. If after an extended stop in sunshine, the
interior temperature is very high, first air
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 condensation created by the air
conditioning results in a discharge of
water under the vehicle which is per fectly
normal.
Stop & Star t
The heating and air conditioning systems
only work when the engine is running.
To maintain a comfortable temperature
in the passenger compartment, you can
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.

Air filter and passenger compartment filter
Refer to the manufacturer’s
ser vice schedule for details of the
replacement intervals 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 .
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
Oil filter
Change the oil filter each time the
engine oil is changed.
Refer to the manufacturer’s
ser vice schedule for details of
the replacement inter val for this
component.
Particle filter (Diesel)
Depending on the version of the instrument
panel you have, the start of saturation of the
particle filter is indicated by:
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
- fixed illumination of the particle filter warning lamp, accompanied
by an audible signal and a
message that there is a risk of
blockage of the particle filter,
or
-
t
emporary illumination of
the Ser vice warning lamp,
accompanied by an audible
signal and a message that
there is a risk of blockage of the
particle filter. On a new vehicle, the first particle
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.
Traffic conditions permitting, regenerate
the filter by driving at a speed of at least
37 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking levels ,
refer to the corresponding section.
