We recommend use of the automatic regulation
of the air conditioning.
It permits automatic and optimised control
of all of the following functions: air flow,
temperature in the passenger compartment
and air distribution, by means of various
sensors (ambient temperature, sunshine).
This eliminates any need for you to change
your settings other than the temperature value
displayed.
F Take care not to cover the sunshine
sensor A.
If you select the automatic mode
(by pressing the "AUTO" control) and leave
all of the vents open, optimum comfort will be
maintained and humidity and condensation will
be removed regardless of the exterior climatic
conditions.
The temperature in the passenger compartment
can only be lower than the ambient temperature
if the air conditioning is on.
In order to be effective, the air conditioning must
be used with the windows closed. If the vehicle
has been parked in the sun for a long period
and the interior temperature is very high, first
ventilate the passenger compartment with the
windows open for a few minutes, then close the
windows.
Heating, ventilation and air conditioning recommendations
To keep the air conditioning system in
good working order it is essential that it is
operated at least once a month.
The air conditioning uses engine power
during its operation. As a result, the fuel
consumption of the vehicle increases.
In certain cases of particularly arduous use
(e.g. towing the maximum load on a steep
gradient in high temperatures), switching off
the air conditioning saves engine power and
improves the towing capacity.
Air inlet
Check that the exterior grille for the air inlet,
at the bottom of the windscreen, is clean and
free of dead leaves, snow, etc.
When washing the vehicle using a high
pressure nozzle, avoid spraying at the air
inlet. Maximum comfort is obtained by means of
a good distribution of air in the passenger
compartment, both in the front and in the rear.
To obtain a uniform distribution of air, take
care not to block the exterior air intake grille
located at the base of the windscreen, the
vents, the air outlets under the front seats and
the air extractor located behind the flaps in
the boot.
The front and rear vents are fitted with
thumbwheels to adjust the air flow and
direction. We recommend that you leave all of
the vents open.
Dust filter / Odour filter
(active carbon)
There is a filter for excluding odours and
dust.
This filter must be changed in line with the
vehicle's servicing schedule. (Refer to the
maintenance and warranty guide).

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.

System which reduces fuel consumption by recommending the most appropriate
g e a r.
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations must
not be considered compulsory. In fact, the
configuration of the road, the amount of traffic
and safety remain determining factors when
choosing the best gear. Therefore, the driver
remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated.Example:
- You are in third gear.
- You press the accelerator pedal.
Gear efficiency indicator*
Operation
With an automatic gearbox, the system
is only active in manual mode.
* Depending on engine. On BlueHDi Diesel 150 versions with manual
gearbox, the system may suggest changing into
neutral so that the engine can go into standby
(STOP mode with Stop & Start), in certain
driving conditions. In this case, N is displayed
in the instrument panel. The information appears in the instrument
panel in the form of an arrow.
On vehicle fitted with a manual gearbox,
the arrow may be accompanied by the gear
recommended.
The system adapts its gear change
recommendation according to the
driving conditions (slope, load, ...) and
the demands of the driver (power,
acceleration, braking, ...).
The system never suggests:
- engaging first gear,
- engaging reverse gear.
- The system may suggest that you engage
a higher gear.

115
Stop & Start
Operation
- with a manual gearbox, at speeds below
12 mph (20 km/h) with BlueHDi Diesel
versions, when you put the gear lever into
neutral and release the clutch pedal,
- with an automatic gearbox, vehicle
stationary, when you press the brake pedal
or place the gear lever in position N .
Going into engine STOP
mode
The "ECO" warning lamp comes on
in the instrument panel and the engine
goes into standby automatically: If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It resets
itself to zero every time the ignition
is switched on with the key.
Special cases: STOP mode
unavailable
In this case, the "ECO"
warning
lamp flashes for a few seconds, then
goes off.
This operation is perfectly normal. STOP mode is not invoked when:
- the vehicle is on a steep slope
(up or down),
- the driver's door is open,
- the driver's seat belt is not fastened,
- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine start using
the key,
- the electric parking brake is applied or
being applied,
- the engine is needed to maintain a
comfortable temperature in the passenger
compartment,
- demisting is active,
- some special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...).
The engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.
STOP mode does not affect the functionality of
the vehicle, such as braking, power steering,
for example.Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key.
