In order for these systems to be fully effective, follow the operation and maintenance guidelines belo w:
F
T
o obtain an even air distribution, take care not to obstruct the exterior air intake grilles
l
ocated 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
o
f the air conditioning system.
F
O
perate the air conditioning system for at least 5 to 10 minutes, once or twice a month
t
o keep it in per fect working order.
F
E
nsure that the passenger compartment filter is in good condition and have the filter
e
lements replaced regularly.
W
e recommend the use of a combined passenger compartment filter. Thanks to its
s
pecial active additive, it contributes to the purification of the air breathed by the
occupants
and the cleanliness of the passenger compartment (reduction of allergic
s
ymptoms, bad odours and greasy deposits).
F
T
o ensure correct operation of the air conditioning system, you are also advised to have
i
t 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
q
ualified
w
orkshop.
Recommendations for ventilation and air conditioning
If after an extended stop in sunshine, the i nterior t emperature i s v ery h igh, f irst
v
entilate the passenger compartment for
a
few moments.
Put
the air flow control at a setting high
e
nough to quickly change the air in the
p
assenger
c
ompartment.
The
air conditioning system does not
c
ontain chlorine and does not present
any
danger to the ozone layer.
The condensation created by the air
conditioning
results in a discharge
o
f water under the vehicle which is
per fectly
normal.

increases
the
available

power
and
so
improves
the
towing
ability.
Stop & Start
The heating and air conditioning s ystems only work when the engine
i
s running. To maintain a comfortable
t
emperature in the passenger
c
ompartment, you can temporarily
d
eactivate the Stop & Start system (see

Driving advice
Distribution of loads
F distribute the load in the trailer so that the heaviest items are as close as
p
ossible to the axle and the nose weight
a
pproaches the maximum permitted
w
ithout exceeding it.
ai
r density decreases with altitude, thus
reducing
engine per formance. Above
1 0
00 metres, the maximum towed load must
b
e reduced by 10 % for every 1 000 metres of
al
titude.
Side wind
F Take into account the increased sensitivity t
o side wind.
Cooling
Towing a trailer on a slope increases the temperature of the coolant.
As
the fan is electrically controlled, its cooling
c
apacity is not dependent on the engine speed.
F
T
o lower the engine speed, reduce your
s
peed.
The
maximum towed load on a long incline
d
epends on the gradient and the ambient
t
emperature.
In
all cases, keep a check on the coolant
t
emperature. F
I
f the warning lamp and the
S
TOP
warning lamp come on,
s
top the vehicle and switch off
the
engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes on a long
m
ountain type of descent, the use of engine
b
raking is recommended.
Ty r e s
F Check the tyre pressures of the towing v
ehicle and of the trailer, observing the
re
commended
p
ressures.
Lighting
F Check the electrical lighting and signalling o
n the trailer.
Refer to the "Technical data" section for details
of
the
weights
and
towed
loads
which
apply
to
y
our
vehicle.
When
not
towing
a
trailer,
remove
the
q
uickly-detachable
tow
ball
before
d
riving. The
rear parking sensors will be
d
eactivated automatically if a genuine
C
ITROËN towbar is used.
