Ventilation
Air intake
The air circulating in the passenger
compartment 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:
-
d
irect arrival in the passenger
compartment (air intake),
-

p
assage through a heating circuit (heating),
-

p
assage through a cooling circuit (air
conditioning).

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.
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 condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.
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.
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.
For more information on Stop & Star t ,
refer to the corresponding section.

Driving recommendations
Observe the driving regulations 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.
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.If you are obliged to drive through water:
-

c
heck 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 km/h),
- d o not stop and do not switch off the
engine.
On leaving the flooded road, as soon as
circumstances allow, make several light brake
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact
a CITROËN dealer or a qualified workshop.
Important!
Never drive with the parking brake
applied - Risk of overheating and
damage to the braking system!
Risk of fire!
As the exhaust system of your vehicle
is very hot, even several minutes after
switching off the engine, do not park
or run the engine over areas where
inflammable substances and materials
are present: grass, leaves, etc.
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.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches the
maximum permitted without exceeding it.
Air density decreases with altitude, thus
reducing engine per formance. Above
1
000 metres, the maximum towed load must
be reduced by 10
% for every 1 000 metres of
altitude.
Side wind
F Take into account the increased sensitivity to side wind.For more information on Weights
, refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
Cooling
Towing a trailer on a slope increases the
temperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F
T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam
height of your vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding section.
