FAMILIARISATION

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 refi t 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 (en-
gine oil, oil fi lter, air fi lter...) and observe
the schedule of operations recommended
by the manufacturer.




When refuelling, do not continue after
the 3 rd cut-off of the nozzle to avoid
any overfl ow.

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.

Switch off the headlamps and front
foglamps when the level of light does
not require their use.

Avoid running the engine before mov-
ing off, particularly in winter; your ve-
hicle will warm up much faster while
driving.

As a passenger, if you avoid connect-
ing your multimedia devices (fi lm, mu-
sic, video game...), you will contribute
towards limiting the consumption of
electrical energy, and so of fuel.
Disconnect your portable devices be-
fore leaving the vehicle.

Air conditioning

To ensure that your system operates
correctly, it is recommended that you
have it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To preserve the sealing of the air
conditioning compressor, operate
the air conditioning at least once a
month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If after a lengthy stop in bright sunlight
the interior temperature is excessive,
air the passenger compartment by
opening the windows for a few mo-
ments, then close them again.
The air conditioning operates by using
power from the engine. This results in
a slight increase in fuel consumption.


Dust filter/Odour filter (active
carbon)
There is a fi lter for excluding odours
and dust.
This fi lter has to be changed in ac-
cordance with the vehicle's servicing
schedule (see the servicing booklet).


Air circulation

Air vents on the fl oor underneath the
front seats provide enhanced heat-
ing for the rear seat positions; take
care not to obstruct them.


Air vents

The air vents to the face have grilles
and thumb wheels to adjust the air
fl ow and direction (up-down, right-
left).
The automatic regulation of the air
conditioning in the passenger com-
partment uses a number of sensors
(sunshine sensor, ambient tempera-
ture sensor...) that relieve you of the
need to make frequent adjustments to
the displayed temperature.
Take care not to obstruct the sun-
shine sensor, located on the dash-
board behind the instrument panel.

Deactivation

Press on button 3
.
This action causes the
information "OFF"
to
appear on the instru-
ment panel screen.
This action does not cancel the
memorised maximum speed which
remains displayed in zone A
of the
instrument panel.


Override of the programmed
speed
The accelerator pedal is equipped
with an end-of-travel switch. If you
action this switch by pressing the
pedal hard down, you can exceed
the memorised maximum speed at
any time.
During the time the speed is be-
ing exceeded, the displayed speed
fl ashes.
You have only to release the ac-
celerator pedal to return below the
maximum speed and render the
function active again.

Return to normal driving



)
By moving the control 1
from po-
sition "LIM"
to position 0
.

)
By the engine stopping.
The speed previously chosen is still
memorised.


Operating fault

If there is a speed limiter malfunc-
tion, a message will display accom-
panied by an audible signal and
lighting of the service warning lamp.
Have it checked by a CITROËN
dealer or a qualifi ed workshop. If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for ex-
ample on a steep descent or under
heavy acceleration) then the speed
fl ashes. Adapt your speed as neces-
sary.
The function will re-engage when
your speed returns below the de-
sired maximum speed.
On a steep downhill gradi-
ent or on sharp accelera-
tion, the speed limiter will
not be able to prevent the vehicle
from exceeding the programmed
speed.
Use of fl oor mats that are not ap-
proved by CITROËN may hinder
access to the accelerator pedal
and thus interfere with the function-
ing of the speed limiter.
To avoid any risk of interfering with
the pedals:


- check that the fl oor mat is cor-
rectly positioned,

- never use more than one fl oor
mat.

Reactivation



)
By recall of the memorised
speed

After a disengagement, press on
button 3
. Your vehicle automati-
cally returns to the memorised
cruise speed which is displayed
in zone A
.
If the memorised cruise speed
is higher than the current speed,
the vehicle will accelerate to
reach the former.

)
By selection of the current
speed

Press on button 2
or 4
once the
desired speed has been reached.
The information "OFF"
will then
disappear from the instrument
panel display.



Overriding the programmed
speed
During the operation of cruise con-
trol, it is always possible to use the
accelerator to go faster than the
cruise speed (for example to over-
take another vehicle). The speed
displayed in zone A
fl ashes.
You have only to release the accel-
erator pedal to return to the cruise
speed. If during the operation of cruise
control, the system is unable to
keep within the memorised speed
(for example on a steep descent),
then the speed fl ashes. Adapt your
speed as necessary.

Return to normal driving
Operating fault
If there is a malfunction, a message
will display accompanied by an audi-
ble signal and lighting of the service
warning lamp.
Have it it checked by a CITROËN
dealer or a qualifi ed workshop.
Cruise control should only
be used when the driving
conditions allow you to drive
at a constant speed.
Do not use it in heavy traffi c, or on
dangerous or slippery roads.
The driver must remain attentive
and in full control of his vehicle.
You are recommended to always
keep your feet within range of the
pedals.
To avoid any risk of interfering with
the pedals:


- check that the fl oor mat is cor-
rectly positioned,

- never use more than one fl oor
mat.

CHECKS






CHECKS












12 V battery

The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, parti-
cularly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection.










Particle filter system (Diesel)

Complementary to the catalytic
converter, this fi lter makes an ac-
tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audible
signal and lighting of the service
warning lamp.
This alert tells you that the particle
fi lter is starting to fi ll up (in conditions
of urban driving of exceptionally long
duration: low speeds, traffi c jams
etc.)
To regenerate the fi lter, it is advised
to drive as soon as possible, when
traffi c conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least fi ve minutes (until
the alert message disappears).
If this alert persists, consult a
CITROËN dealer or a qualifi ed
workshop.





The presence of this label, in par-
ticular with the Stop & Start system,
indicates the use of a specifi c 12 V
lead-acid battery with special tech-
nology and specifi cation, for which
the involvement of a CITROËN
dealer or a qualifi ed workshop is
required when replacing or discon-
necting the battery. Failure to observe this recommen-
dation may shorten the life of the
battery.
Unless otherwise indicated, check
these components in accordance
with the servicing booklet and ac-
cording to your engine.
Otherwise, have them checked by
a CITROËN dealer or a qualifi ed
workshop.





















Air filter and passenger
compartment filter
Refer to the servicing
booklet for details of the
replacement intervals for
these components.
Depending on the environ-
ment (e.g. dusty atmosphere) and
the use of the vehicle (e.g. city driv-
ing), replace them twice as often
if necessary
(refer to the "Engines"
section).
A clogged passenger compartment
fi lter may have an adverse effect on
the performance of the air condition-
ing system and generate undesir-
able odours.














Oil filter

Replace the oil fi lter each
time the engine oil is
changed.
Refer to the servicing
booklet for details of the
replacement interval for this compo-
nent.

PRACTICAL INFORMATION

Towbar suitable for the attachment
of a trailer with additional lighting
and signalling.
Your vehicle is primarily designed
for transporting people and luggage,
but it may also be used for towing a
trailer.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
of your vehicle, and that the fi t-
ting of the towbar is entrusted to
a CITROËN dealer or a qualifi ed
workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is imperative
that it is fi tted in accordance with the
vehicle manufacturer's instructions.

Driving advice


Distribution of loads


)
Distribute the load in the trailer
so that the heaviest items are as
close as possible to the axle and
the nose weight approaches the
maximum permitted without ex-
ceeding it.
Air density decreases with altitude,
thus reducing engine performance.
Above 1 000 metres, the maximum
towed load must be reduced by 10 %
for every 1 000 metres of altitude.
Refer to the "Technical Data" section
for details of the weights and towed
loads which apply to your vehicle.

Side wind


)
Take into account the increased
sensitivity to side wind.


)
To lower the engine speed, re-
duce your speed.
The maximum towed load on a long
incline depends on the gradient and
the ambient temperature.
In all cases, keep a check on the
coolant temperature.


)
If the warning lamp and
the STOP
warning lamp
come on, stop the vehicle
and switch off the engine
as soon as possible.


Braking
Towing a trailer increases the brak-
ing distance.
To avoid overheating of the brakes
on a long mountain type of descent,
the use of engine braking is recom-
mended.

Tyres


)
Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended
pressures.


Lighting


)
Check the electrical lighting and
signalling on the trailer.
The rear parking sensors will be
deactivated automatically if a gen-
uine CITROËN towbar is used.
Driving with a trailer places greater
demands on the towing vehicle and
the driver must take particular care.

Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled,
its cooling capacity is not dependent
on the engine speed.
