has a fault (dirty or loose
terminals, slack or cut
alternator belt, ...). The warning lamp should go off when the engine
is started.
If it does not go off, contact a CITROËN dealer or
a qualifi ed workshop.




Low fuel level


fi xed. When it fi rst comes on there
remains approximately
5 litres of
fuel
in the tank. You must refuel as soon as possible to avoid
running out of fuel.
This warning lamp will come on every time the
ignition is switched on, until a suffi cient addition
of fuel is made.

Fuel tank capacity: approximately 50 litres

COMFORT
VENTILATION

Air intake

The air circulating in the passenger com-
partment is fi ltered and originates either
from the outside via the grille located at
the base of the windscreen or from the
inside in air recirculation mode.
Air treatment

The incoming air follows various routes
depending on the controls selected by
the driver:


- direct arrival in the passenger com-
partment (air intake),

- passage through a heating circuit
(heating),

- passage through a cooling circuit
(air conditioning).
The temperature control enables you to
obtain the level of comfort required by
mixing the air of the various circuits. The air distribution control enables you
to diffuse the air in the passenger com-
partment combining several air vents.
The air fl ow control enables you to
increase or reduce the speed of the
ventilation blower.

The controls of this system are grouped
together on control panel A
on the centre
console. Depending on the model, the
functions offered are:


- the level of comfort required,

- air fl ow,

- air distribution,

- demisting-defrosting,

- manual or digital air conditioning
controls.

tioning is resumed when the button is
pressed again. The symbol "A/C"
is
displayed.

5. Air intake/Air recirculation
Press this button for recircula-
tion of the interior air. The air
recirculation symbol 5
is dis-
played.
Air recirculation enables the passenger
compartment to be isolated from exte-
rior odours and smoke.
6. Air distribution adjustment Avoid prolonged recirculation of
interior air (risk of condensation
or deterioration of the air quality).
Pressing this button several
times in succession enables
the air fl ow to be directed in
turn towards:

gressively according to the value re-
quested.

Switching the system off
Avoid driving for long periods
with the air conditioning switched
off (risk of misting and reduction
of the air quality in the cabin). Press the air fl ow "empty fan"

button 7
until the fan symbol
disappears.
This action switches off all of the func-
tions of the air conditioning system.

CHECKS
CHECKING LEVELS
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.

Oil level

The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 30 minutes.
The check is carried out either when the igni-
tion is switched on using the oil level indicator
in the instrument panel, or using the dipstick.

Engine oil change
Refer to the servicing booklet for details
of the interval for this operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.

Oil grade
The oil must be suitable for your en-
gine and conform to the manufacturer's
recommendations.


The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.

Changing the fl uid
Refer to the servicing booklet for details
of the interval for this operation.

Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.

Coolant level

The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the igni-
tion off.

On vehicles which are fi tted with a par-
ticle emission fi lter, the fan may ope-
rate after the vehicle has been switched
off, even if the engine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work. To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

Changing the coolant

The coolant does not have to be changed.


Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.



Screenwash fluid level

Top up the level when neces-
sary.

Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with plain water.



Take care when carrying out
checks under the bonnet as
some parts of the engine can be
very hot (risk of burns).


It is normal to top up the engine oil
between services. CITROËN recom-
mends that you check the oil level and
top up if necessary, every 3 000 miles
(5 000 kilometres).

PRACTICAL INFORMATION
We recommend the use of genu-
ine CITROËN towbars and their
harnesses that have been tested
and approved from the design
stage of your vehicle, and that
the fi tting of the towbar is en-
trusted to a CITROËN dealer or
a qualifi ed workshop.
If the towbar is not fi tted by a
CITROËN dealer, it is impera-
tive that it is fi tted in accordance
with the vehicle manufacturer's
instructions.
TOWING A TRAILER, ...
The rear parking sensors will
be deactivated automatically if
a genuine CITROËN towbar is
used.

Towbar suitable for the attachment of a
trailer with additional lighting and signal-
ling.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer. Driving with a trailer places greater de-
mands on the towing vehicle and the
driver must take particular care.
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 exceeding 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.


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.


)
To lower the engine speed, reduce
your speed. The maximum towed load on a long in-
cline 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 braking
distance.
To avoid overheating of the brakes on a
long mountain type of descent, the use
of engine braking is recommended.

Tyres


)

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



Lighting


)
Check the electrical lighting and sig-
nalling on the trailer.
