5. Air flow adjustment
Reducing the air flow to minimum switches
the air conditioning system OFF.
To prevent condensation and deterioration
of the quality of the air in the passenger
compartment, ensure that an adequate flow of
air is maintained.
6. Air conditioning
The air conditioning will only
operate when the engine is running.
The air blower control (air flow
adjustment) must be active in order
to obtain air conditioning.
7. Intake of exterior air /

While retaining the other settings, this position
allows the driver to isolate the passenger
compartment at any time from unpleasant
exterior odours and fumes.
F
Press the control:
- to increase the air flow,
- to reduce the air flow.
The air flow level is indicated by the
progressive illumination of the fan
blade indicator lamps.
This function permits recirculation of the air
and isolation the passenger compartment from
exterior fumes and odours. It is inactive when
the ambient temperature is below +5 °C to
avoid the risk of misting inside the vehicle.
You can store the settings of the air
conditioning system. Refer to the

9. Front demisting / defrosting
In certain cases, the "AUTO"
mode may not be sufficient to
demist or defrost the windows
(humidity, several passengers,
i c e).
8. Rear demisting / defrosting
The heated rear screen operates
independently of the air
conditioning system.
F Press control 8 , with the engine running, to
demist the rear screen and the mirrors. The
indicator lamp comes on.
Demisting is switched off automatically to
avoid excessive consumption of current and
depending on the exterior temperature.
It may be stopped by pressing control 8 again
or when the engine is switched off.
In this latter case, the demisting resumes if the
engine is switched on again within one minute. F
Press control 9 to clear the windows
quickly. The indicator lamp comes on.
This system controls the temperature, air flow
and intake and distributes the ventilation to the
windscreen and front side windows.
Resuming manual control exits from the
"Demisting" mode. It must be cancelled as
soon as possible to permit renewal of the air in
the passenger compartment and demisting.
Pressing one of the controls 1a or 1b returns
the system to the "AUTO" mode.
With Stop & Start, when demisting has
been activated, the STOP mode is not
available. When starting with the engine cold,
air flow will reach its optimum level
gradually to prevent an excessive
distribution of cold air.
When entering the vehicle after it has
been parked for a fairly long period, if
the interior temperature is very different
from your comfort setting there is
no need to change the temperature
displayed in order to quickly reach the
level of comfort required. The system
automatically uses its maximum
per formance to correct the difference in
temperature as quickly as possible.
The water resulting from the air
conditioning condensation is
discharged via an opening provided
for this purpose; therefore, a puddle of
water may form underneath the vehicle
when stationary.
In all seasons, if the weather is cool,
the air conditioning is useful as it
removes the humidity from the air
and the condensation. Avoid driving
for prolonged periods with the air
conditioning switched off.
Switch off the rear screen and
exterior mirrors demisting when you
consider this necessary as low current
consumption reduces fuel consumption.

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.
Driving recommendations
Important!
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!
n ever 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.
If you are obliged to drive through water:
-
check that the depth of water does not
exceed 15 cm, taking account of waves
that might be generated by other users,
- deactivate the Stop & Start system,
- drive as slowly as possible without
stalling. In all cases, do not exceed 6 mph
(10 km/h),
- do 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.

Anti-theft protection
Electronic engine immobiliser
The key contains an electronic chip which has
a special code. When the ignition is switched
on, this code must be recognised in order for
starting to be possible.In the event of a fault, you are
informed by illumination of this
warning lamp, an audible signal and
a message in the screen.
In this case, your vehicle will not start; contact
a CITROËN dealer as soon as possible.
Starting-switching off the engine
Keep safely, away from your vehicle,
the label attached to the keys given to
you on acquisition of the vehicle.
Ignition switch
It has 3 positions:
- position 1 (Stop): insert and removing
the key,
- position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating,
engine running,
- position 3 (Starting).
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Avoid attaching heavy objects to the
key or the remote control, which would
weigh down on its blade in the ignition
switch and could cause a malfunction.
It could adversely affect the deployment
of the front airbag.
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.
Once the state of charge of the battery drops
to the reserve level, the system switches to
energy economy mode: the power supply is
cut off automatically to preserve the remaining
battery charge.

Starting the engine
Wait until this warning lamp goes off in the
instrument panel then operate the starter
motor by turning the key to position 3
without pressing the accelerator pedal,
until the engine starts. Once the engine is
running, release the key.
With the parking brake applied and the gearbox
in neutral or position N or P:
F depress the clutch pedal fully (manual
gearbox),
or
F press the brake pedal firmly (automatic
gearbox),
F insert the key into the ignition switch; the
system recognises the code,
F unlock the steering column by simultaneously
turning the steering and the key.
F With a petrol engine, operate the starter
motor by turning the key to position 3
without pressing the accelerator pedal,
until the engine starts. Once the engine is
running, release the key. Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion
engines emit toxic exhaust gases,
such as carbon monoxide. Danger of
intoxication and death!
In very severe wintry conditions
(temperatures below -23°C), to ensure
the correct operation and durability of
the mechanical components of your
vehicle, engine and gearbox, it is
necessary to leave the engine running
for 4 minutes before moving off.
In wintry conditions, the warning lamp
can stay on for a longer period. When
the engine is hot, the warning lamp
does not come on.
In certain cases, you may have to apply
more force to the steering (wheels on
full lock, for example). F
With a Diesel engine, turn the key to
position 2 , ignition on, to operate the
engine pre-heating system.
If the engine does not start straight
away, switch off the ignition. Wait a
few moments before operating the
starter motor again. If the engine does
not start after several attempts, do not
keep trying: you risk damaging the
starter motor or the engine. Contact
a CITROËN dealer or a qualified
workshop. In temperate conditions, do not leave
the engine at idle to warm up but move
off straight away and drive at moderate
speed.
