AT A GLANCE
Limit the causes of excess consumption
Spread loads throughout the vehicle; place the heaviest items in
the bottom of the boot, as close as possible to the rear seats.
Limit the loads carried in the vehicle and reduce wind resistance
(roof bars, roof rack, bicycle carrier, trailer...). Use a roof box in
preference.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit your summer
tyres.
Observe the recommendations on maintenance
Check the tyre pressures regularly, when cold, referring to the
label in the door aperture, driver's side.
Carry out this check in particular:
- before a long journey,
- at each change of season,
- after a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or
caravan.
Have your vehicle serviced regularly (engine oil, oil filter, air
filter, cabin filter...) and observe the schedule of operations in the
maintenance and warranty guide.
When refuelling, do not continue after the 3
rd cut-off of the nozzle
to avoid any overflow.
At the wheel of your new vehicle, it is only after the fi rst 1 800 miles
(3 000 kilometres) that you will see the fuel consumption settle
down to a consistent average.

Starting and stopping
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.
Perfect for urban use, the Stop & Start
system reduces fuel consumption and
exhaust emissions and offers the comfort
of complete silence when stationary.
STOP & START
Operation
Going into engine STOP mode
With the vehicle stationary, put the gear
lever into neutral, then release the clutch
pedal. - The "S" warning lamp comes on in the instrument
panel and the engine goes
into standby. Automatic stopping of the engine is
only possible after the vehicle has
exceed a speed of about 6 mph (10 km/h),
to avoid repeated stopping of the engine
when driving slowly.
Never leave your vehicle with out first
turning off the ignition with the key.
Never refuel with the engine
in STOP mode; you must switch
off the ignition with the key. Special cases: STOP mode
unavailable
The STOP mode is not invoked when:
- the system is initialising,
- the driver's door is open,
- the driver's seat belt is not fastened,
- the air conditioning is running,
- the heated rear screen is on,
- the windscreen wiper is on fast wipe,
- reverse gear is engaged, for a parking
manoeuvre,
- some special conditions (battery charge, engine temperature, particle
filter regeneration, braking assistance,
ambient temperature...) where the
engine is needed to assure control of
a system.
The "S" warning lamp flashes for
a few seconds, then goes off.
This operation is perfectly normal.

DEMISTING AND DEFROSTING
Manual mode
Direct the control to this air
distribution setting.
For faster and more effective
demisting and defrosting of
the windscreen: Defrosting the rear screen
and mirrors
Only operates when the engine
is running. Pressing this button
activates the rapid demisting-
defrosting of the rear screen and
door mirrors.
This function switches off automatically to
prevent excessive energy consumption. It
stops when the engine is switched off but
resumes when the engine is started again.
Pressing this button switches the function off.
- increase the air flow setting,
Returning to the exterior air
intake position permits renewal
of the air in the passenger
compartment.
Windscreen and side windows
The ventilation outlets located at the base
of the windscreen and the side vents for the
side windows increase the effectiveness
of the demisting and defrosting. Do not
obstruct these air outlets.
The pollen filter continuously and effectively
filters dust.
Air recirculation (which can be activated by
the driver or the passenger) isolates the
passenger compartment from the exterior
atmosphere. However, this position should
only be used temporarily, normal use is to
drive with the control positioned with the
exterior air intake open.
- move the exterior air intake
control temporarily to air
recirculation.
With Stop & Start, when the heated
rear screen is switched on, the STOP
mode is not available.

EASE OF USE
and
COMFORT
Ventilation
CORRECT USE OF THE AIR CONDITIONING
In order to be effective, the air conditioning
should only be used with the windows
closed. However, if the interior temperature
remains high after a prolonged period
parked in the sun, first ventilate the
passenger compartment for a few minutes. For even air distribution, ensure that the
exterior air intake grille located at the base
of the windscreen, the side and central
vents, the air outlets on the floor and the air
extractor at the rear are not obstructed.
The air conditioning is useful in all seasons
as it eliminates condensation and air
humidity. Operate the air conditioning system for
5 to 10 minutes, once or twice a month,
to keep it in good working order.
Have the filter elements (air filter and
passenger compartment filter) replaced
regularly. If you drive in a dusty environment,
have them replaced twice as often.
It is normal that the condensation created by
the air conditioning system results in a flow
of water which may form a puddle under the
vehicle when parked.
If the system does not produce cold air,
do not use it and have it checked by a
CITROËN dealer or a qualified workshop.
"Leave them open"
For optimum distribution and diffusion of hot
or cool air in the passenger compartment,
there are: 4 adjustable central vents, of
which 2 can be directed sideways (right
or left) towards the top of the body and
4 side vents which can be directed towards
the passengers. The air vents directed
towards the floor of the vehicle complete the
equipment.

Levels and checks

The presence of this label, in particular
with the Stop & Start system, indicates the
use of a specific 12 V lead-acid battery
with special technology and specification.
The involvement of a CITROËN dealer
or a qualified workshop is essential when
replacing or disconnecting the battery. These operations will keep your vehicle
in good running order. Ask for advice
from a CITROËN dealer or refer to the
maintenance and warranty guide included in
the handbook pack.
CHECKS
Battery
At the start of winter, have your battery
checked by a CITROËN dealer or a qualified
workshop.
Bleeding water from the Diesel filter
If this warning lamp comes on,
bleed the filter, or bleed regularly
each time the engine oil is
changed.
To drain the water out, unscrew the bleed
screw or the water in Diesel sensor, located
at the base of the filter. Leave open until
all of the water has been drained out. Then
tighten the bleed screw or the water sensor.
Air filter and passenger compartment filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are given in
the maintenance and warranty guide.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary.
Refer to the "Checks - Under the
bonnet" section.
HDi engines use advanced technology.
All work requires a special qualification
which is guaranteed by a CITROËN dealer
or a qualified workshop.

Levels and checks
Operating fault
If this alert persists, do not ignore the
warning; it indicates that a fault has occurred
in the exhaust / particle filter system.
Have the whole system checked by a
CITROËN dealer or a qualified workshop.
If there is risk of blockage of the
filter, this warning lamp comes on
in the instrument panel.
Saturation / Regeneration Because of the higher exhaust
gas temperature resulting from the
normal operation of the particle filter, it is
recommended that you do not park the
vehicle over inflammable materials (grass,
dry leaves, pine needles, ...) so as to avoid
any risk of fire.
Particle filter system (Diesel)
An addition to the catalytic converter, this
filter makes an active contribution to the
preservation of air quality by the retaining
of the unburnt pollutant particles. Black
exhaust fumes are thus no longer emitted.
Operation
This filter, fitted to the exhaust system,
accumulates particles of soot. The engine
management unit controls the automatic
periodic elimination of the soot particles
(regeneration).
The regeneration procedure is invoked
according to the quantity of particles
accumulated and the driving conditions
of the vehicle. During this phase, you
may notice some unusual phenomena -
increased idling speed, cooling fan running,
increase in smoke and higher exhaust gas
temperature - which does not affect the
operation of the vehicle or the environment. After prolonged idling or driving at very
low speeds, you may occasionally
notice water vapour being emitted from the
exhaust when accelerating. This is of no
consequence to the running of the vehicle or
to the environment. To regenerate the filter, it is advised to drive
as soon as possible, when traffic conditions
and the law permit, at a speed of at least
40 mph (around 60 km/h), with an engine
speed above 2 000 rpm for about fifteen
minutes (until the warning lamp and/or the
message disappears).
If possible, avoid switching off the engine
before the end of regeneration of the
filter; repeated interruptions could cause
premature deterioration of the engine oil. It
is not recommended to end regeneration of
the filter with the vehicle stationary.
This alert tells you that the particle filter
is starting to fill up (in conditions of urban
driving of exceptionally long duration: low
speeds, traffic jams etc.)
