Instruments and controls
FUEL GAUGE
The fuel level is tested each time the key is
turned to the "running" position.
The gauge is positioned on:
- 1: the fuel tank is full, approximately
80 litres.
- 0: the reserve is now being used, the
warning light comes on continuously.
COOLANT TEMPERATURE

The needle is positioned before the red
zone: normal operation.
In arduous conditions of use or hot climatic
conditions, the needle may move close to
the red graduations.
What you should do if the warning light
comes on:
- stop immediately, switch off the ignition. The fan may continue to operate for a
certain time up to approximately
10 minutes.
- wait for the engine to cool down in order to check the coolant level and top it up if
necessary.
Refer to the "Fuel" section of chapter 6.
What you should do if the needle enters
the red zone:
Reduce your speed or let the engine run at
idle. Refer to the "Levels" section of
chapter 6.
The reserve when the warning first
comes on is approximately 8 litres. As the cooling system is pressurised, follow
this advice in order to avoid any risk of
scalding:
- wait at least one hour after switching off
the engine before carrying out any work,
- unscrew the cap by 1/4 turn to allow the pressure to drop,
- when the pressure has dropped, check the level on the expansion bottle,
- if necessary, remove the cap to top up.
If the needle remains in the red zone, have
the system checked by a CITROËN dealer.

ERGONOMICS AND COMFORT
3
Intake of exterior air Recommended settings
For optimum operation of the manual system, the se ttings below are recommended:
The diode on the button is off.
This is the preferred operating
position.
Recirculation of interior air The diode on the button is lit.
Recirculation temporarily prevents
exterior odours and smoke
from entering the passenger
compartment.
Used with the air conditioning switched on
and setting of the force of blown air (from
1 to 4), recirculation enables you to obtain
the required ambient air comfort level more
quickly with both hot or cold settings.
This position should only be temporary.
When your ambient air comfort level has
been reached, return to the intake of exterior
air position to permit renewal of the air in the
passenger compartment and avoid misting.
This operating mode is preferable. If I require...

AUTOMATIC AIR CONDITIONING WITH SEPARATE ADJUSTMENTS
Good practice
For maximum cooling or heating of the
passenger compartment, it is possible to exceed
the value 15 by turning until LO is displayed or
the value 27 by turning until HI is displayed.
For optimum comfort, the difference between
the value displayed for the driver and for the
passenger should not be greater than 3.
If your vehicle is fitted with this control
panel, it is located on the centre console.
On entering the vehicle, the inside
temperature may be much colder (or
warmer) than is comfortable. There is no
advantage in changing the value displayed
in order to quickly reach the level of comfort
required. The system will use its maximum
performance to reach the comfort value set.

Ventilation Air flow
Press the small fan button to
reduce the flow or the large fan
button to increase the flow.
On the display, the blades of the fan darken
when the flow is increased.
Manual operation
You can, according to your requirements,
make a different selection from that offered
by the system by changing a setting.
The other functions will still be controlled
automatically. Pressing the
AUTO button
restores fully automatic operation. Intake of exterior air/
Recirculation of interior air
Press this button to recirculate
the interior air. The recirculation
symbol is displayed.
Recirculation prevents exterior odours
and smoke from entering the passenger
compartment. Avoid prolonged operation
in interior air recirculation mode (risk of
condensation, odour and humidity).
Pressing this button again activates the
intake of exterior air.
Air distribution
Pressing this button several times
in succession directs the air flow
towards:
- the windscreen,
- the windscreen and footwells,
- the footwells,
- the side vents, central vents and footwells,
- the side vents and central vents. Deactivating the system
Press the air flow
small fan
button until the fan symbol
disappears.
This action deactivates all of the
system's functions, with the exception of the
air recirculation and rear screen demisting (if
fitted on your vehicle). Your comfort setting
is no longer maintained and is switched off.
For your comfort, do not deactivate the
system for long periods.
Pressing the large fan button or
the AUTO button reactivates the
system with the values set before
it was deactivated. Switching the air conditioning
On/Off
Press this button, the
A/C
symbol is displayed and the air
conditioning is activated.
Pressing this button again switches off the
air cooling.

Towing a trailer

For more information about weights,
refer to the administrative documents
(V5 registration document, ...) or to the
"Weights" section of chapter 8.
TOWING A TRAILER, CARAVAN, BOAT, ETC...

Distribution of loads
Distribute the load in the trailer so that the
heaviest objects are as close as possible
to the axle and the nose weight is close to
the maximum authorised without, however,
exceeding it.
Cooling
Towing a trailer on a slope increases the
coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on the
engine speed.
Driving advice
A towed vehicle must free wheel: gearbox in
neutral.

CHECKS

Cooling system
Only use the fluid recommended by the
manufacturer.
Otherwise, you risk seriously damaging your
engine.
When the engine is warm, the temperature
of the coolant is controlled by the engine
fan. As this fan can operate with the ignition
key removed and because the cooling
system is pressurised, wait for at least one
hour after the engine has stopped before
carrying out any work.
Slacken the cap by 1/4 of a turn to release
the pressure to prevent any risk of scalding.
When the pressure has dropped, remove the
cap and top up the level with coolant.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer as soon as possible. Power steering fluid level
The vehicle must be parked on level ground
with the engine cold. Unscrew the cap
integrated with the gauge and check the
level which must be between the MIN and
MAX marks.
When this occurs with the engine running it
is due to the start of saturation of the particle
emission filter (exceptionally prolonged
urban type driving conditions: low speed,
long traffic jams, ...).
In order to regenerate the filter, you are
advised to drive at a speed higher than
40 mph (60 km/h) for at least five minutes
as soon as possible, when traffic conditions
permit (until the message disappears and
the service warning light is switched off).
During regeneration of the particle emission
filter, relay noise may be heard under the
fascia.
If the message is still displayed and if the
service warning light remains on, contact a
CITROËN dealer.
Topping up
The level must be between the MIN and
MAX marks on the expansion bottle. If
more than 1 litre of fluid is required to top
up the level, have the system checked by a
CITROËN dealer. Windscreen wash and headlamp
wash level
For best quality cleaning and for your safety,
we would advise that you use products of
the CITROËN Universal range.
Capacity of the screenwash reservoir:
approximately 4.5 litres.
If your vehicle is fitted with headlamp
washers, the capacity of the reservoir is
7.5 litres.
To guarantee optimum cleaning and prevent
freezing, this fluid must not be topped up or
replaced with water.
Diesel additive level (Diesel
with particle emission filter)
The minimum level of this additive
is indicated by lighting of the
service warning light, accompanied by
an audible signal and a message on the
display. Topping up
It is imperative that this additive is topped up
by a CITROËN dealer without delay.
