FAMILIARISATION
EXTERIOR


Stop & Start

This system puts the engine tempo-
rarily into standby during stops in the
traffi c (red lights, traffi c jams, etc...).
The engine restarts automatically as
soon as you want to move off.
Stop & Start reduces fuel consump-
tion, exhaust emissions and noise
when stationary.

Lane departure warning system


This driving aid warns you when you
unwittingly cross a lane marking.

Parking sensors (visual and
audible)

This system warns you if an obstacle
is detected in front of or behind the
vehicle.
Tyre under-infl ation detection

This system checks the pressure
of the tyres automatically while
driving.
Xenon dual-function directional
headlamps

This system automatically provides
you with extra visibility on bends.
This lighting is linked with the cor-
nering lighting which maximises the
illuminated area at intersections and
when parking.

Panoramic sunroof (Tourer)

This roof provides you with perfect
brightness in the passenger com-
partment.

Sunroof (Saloon)

This also provides you with im-
proved ventilation in the passenger
compartment.

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
(engine 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.

COMFORT

Air conditioning

We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following functions:
air fl ow, temperature in the passenger
compartment and air distribution, by
means of various sensors (ambient
temperature, sunshine). This elimi-
nates any need for you to change
your settings other than the tempera-
ture value displayed.


)
Take care not to cover the sun-
shine sensor A
.
If you select the automatic mode
(by pressing the "AUTO" control)
and leave all of the vents open, opti-
mum 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.














HEATING, VENTILATION
AND AIR CONDITIONING
RECOMMENDATIONS 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 tempera-
ture is very high, fi rst ventilate the
passenger compartment with the
windows open for a few minutes,
then close the windows.
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 ardu-
ous 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 wind-
screen, is clean and free of dead
leaves, snow, etc.
When washing the vehicle using a
high pressure nozzle, avoid spraying
at the air inlet.


Air circulation

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 ex-
terior 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 fl aps in the boot.
The front and rear vents are fi tted
with thumbwheels to adjust the air
fl ow and direction. We recommend
that you leave all of the vents open.


Dust filter/Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter must be changed in line
with the vehicle’s servicing schedule
(see the vehicle’s servicing booklet).

DRIVING








GEAR EFFICIENCY
INDICATOR *

System which reduces fuel con-
sumption by advising the driver to
change up on vehicles fi tted with a
manual gearbox.

Operation

The system intervenes only when
driving economically.
Depending on the driving situation
and your vehicle's equipment, the
system may advise you to skip one
or more gears. You can follow this
instruction without engaging the in-
termediate gears.
The gear engagement recommen-
dations must not be considered
compulsory. In fact, the confi gu-
ration of the road, the amount of
traffi c and safety remain determin-
ing 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.

* According to engine.
Example:


- You are in third gear.

- You press the accelerator pedal
moderately.

- The system may suggest that
you engage a higher gear, if ap-
propriate.
The information appears in the in-
strument panel screen in the form of
an arrow accompanied by the sug-
gested gear.

In the case of driving which
makes particular demands on
the performance of the engine
(fi rm pressure on the accelerator
pedal, for example, when overtak-
ing...), the system will not recom-
mend a gear change.
The system never suggests:


- engaging fi rst gear,

- engaging reverse gear,

- engaging a lower gear.

PRACTICAL INFORMATION









Matt paint

If you vehicle is fi nished with a clear
matt lacquer, please observe the fol-
lowing recommendations to avoid
damaging the paintwork by the use
of an inappropriate procedures.
These recommendations are also
valid for alloy road wheels fi nished
with clear matt lacquer.
Never clean the vehicle without water.
Never wash your vehicle in an automatic roller brush car wash.
Never polish the vehicle body, nor the alloy wheels. Doing this will make the
paintwork shiny.
Do not use paint cleaners, abrasive products or paint polishing or preserving
products (such as wax, for example) on the paintwork. These products are
only suitable for bright fi nishes. Application of these products on vehicles
with a matt fi nish will seriously damage the paint surface of the vehicle, giving
rise to irreversible shiny or stained areas.
Never use a high pressure jet wash with a lance fi tted with a brush, this may
scratch the paintwork.
Never select a wash programme that fi nishes with a hot wax cycle.

We recommend the use of a high pressure jet wash, or at least a water hose
with a high output.
We recommend that the vehicle be rinsed using de-ionised water.
Use only a microfi bre cloth to dry the vehicle. It must be clean and used
without heavy pressure.
Lightly wipe off any fuel stains present on the lacquer using a soft cloth, then
leave to dry.
From the range of cleaning and maintenance products recommended and approved
by CITROËN, use only products for removing insects and car shampoo.
Always have paint repairs done by a CITROËN dealer or a qualifi ed workshop.
