A child sur veillance mirror is installed above the
interior mirror. This allows you to keep watch
over the passengers in the back of the vehicle
and facilitates discussion between passengers
in the front and the back without needing to
adjust the mirror and without turning around. It
can be easily folded to avoid dazzle.
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).
Control panel
The controls of this system are accessible in the
Air conditioning menu of the touch screen A .

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 have the
filter elements replaced regularly. 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). 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 may
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.
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.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d

o not drive for too long with the
ventilation switched off.
-

d

o not keep air recirculation set for an
extended period.

Recirculation of interior air
The intake of exterior air helps avoid and
eliminate misting of the windscreen and side
windows.
Recirculation of the interior air isolates the
passenger compartment from exterior odours
and fumes.
When required, this function can also be
used to speed up the heating or cooling of
the passenger compartment.

Driving advice
Observe 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.
As a safety measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
On a
long journey, taking 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 leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. There is a
risk of poisoning and
death!
In very severe wintry conditions
(temperatures below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle
(engine and gearbox), the engine must be
left running for 4
minutes before driving.
Important!
Never drive with the parking brake applied
– Risk of overheating and damage to the
braking system!
As the exhaust system of your vehicle
is very hot, even several minutes after
switching off the engine, never park or run
the engine on inflammable sur faces (dry
grass, fallen leaves, etc.) – Risk of fire!
Never leave a vehicle unsuper vised 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. If you are obliged to drive on a
flooded road:
-
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 function,
-
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 safety
conditions 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.

In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Side wind
F Take into account the increased sensitivity to wind.
Cooling
Towing a trailer on a slope increases the
t emperature 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 towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a
check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
New vehicle
Do not pull a trailer before having driven at least
approximately 620


miles (1,000

kilometres).
Braking
Towing a trailer increases the braking distance.
T o 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 Headlamp
adjustment , refer to the corresponding
section.
Certain driving or manoeuvring aid
functions are automatically disabled if an
approved towing system is used.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic chip which has
a secret code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.
This electronic engine immobiliser locks the
engine management system a
few moments
after the ignition is switched off, and prevents
starting of the engine by anyone who does not
have the key.
In the event of a
malfunction, you are informed
by a
message in the instrument panel screen.
If this happens, your vehicle will not start;
contact a
CITROËN dealer if required.
