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:
F

T

o 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.
F

D

o not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the 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 order.
F

E

nsure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly.
W

e 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).
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 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.
Stop & Start
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 (see the corresponding section).

Windscreen and headlamp wash
Windscreen wash
F Pull the windscreen wiper stalk towards you. The windscreen wash then the
windscreen wipers operate for a fixed
period.
It operates only when the headlamps are off or
the vehicle is stationary.
Low screenwash / headlamp
wash fluid level
On vehicle fitted with headlamp washers, the
low level of this fluid is indicated by gauge in
the reservoir filler neck under the bonnet.
Checking and topping up this fluid can should
be done with the engine off.
The level of this fluid should be
checked regularly, particularly during
w i n t e r.
Refer to the "Checks - Screenwash / headlamp
wash level" section for the procedure on
checking the level.
Headlamp wash
Associated with the windscreen wash, the
headlamp washers operate with the vehicle
moving, when the dipped or main beam
headlamps are on .
To reduce the consumption of the fluid
by the headlamp washers, they operate
only with every seventh use of the
screenwash or every 25 miles (40 km)
during a given journey.
Visibility

A few driving recommendations
Observe the driving regulations at all times and remain vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your hands on the wheel so that you are ready to react at
any time to any eventuality.
On a long journey, a break every two hours is strongly recommended.
In difficult weather, drive smoothly, anticipate the need to brake and increase the distance from
other vehicles.Never drive with the parking brake
applied - Risk of overheating and
damage to the braking system!
Do not park or run the engine when
stationary in areas where inflammable
substances and materials (dry grass,
dead leaves...) might come into contact
with the hot exhaust system - Risk of
fire!
Never leave a vehicle unsupervised
with the engine running. If you have
to leave your vehicle with the engine
running, apply the parking brake
and put the gearbox into neutral or
position


N or P, depending on the type
of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle.
Important!
- check that the depth of water does not exceed 15 cm, taking account of waves
that might be generated by other users,
-

d
eactivate the Stop & Start system,
-

d
rive as slowly as possible without
stalling. In all cases, do not exceed
6 mph (10
