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:
- F (Full): the fuel tank is full,
approximately 90 litres.
- E (Empty): the reserve is now being
used, the warning light comes on
continuously.
The reserve when the warning first comes
on is approximately 11 litres.
Fuel tanks of different capacities (60 and
125 litres) are available as an option.
COOLANT TEMPERATURE

The needle is positioned between
C (Cold) and H (Hot): normal operation.
In arduous conditions of use or hot climatic
conditions, the needle may move close to
the red graduations. - wait for the engine to cool down in
order to check the level and top it up if
necessary. Follow this advice:
the cooling system is pressurised. In order to
avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, check the
level and remove the cap to top up.
If the needle remains in the red zone,
contact a CITROËN dealer.
Refer to the "Levels" section of
chapter 7.
Refer to the "Fuel" section of chapter 7.
What you should do if the needle enters the
red zone, or 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.
EMISSION CONTROL
EOBD (European On Board Diagnosis) is
a diagnostics system which complies with,
among others, the standards concerning
authorised emissions of:
- CO (carbon monoxide),
- HC (unburnt hydrocarbons),
- NOx (nitrogen oxides) or particles, detected by oxygen sensors placed
upstream and downstream of the
catalytic converters.
Therefore, the driver is warned of any
malfunction of this emission control
system by the lighting of this specifi c
warning light on the instrument panel.
There is a risk of damage to the catalytic
converter. Have it checked by a CITROËN dealer.

ERGONOMICS AND COMFORT
Ventilation
Intake of exterior air
Recommended settings for the air conditioning Recommended settings for the air conditioning
For optimum operation of the system, the settings below are recommended:
Recirculation of interior air
This position should only be
temporary.
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 with both hot or cold
settings.
Recirculation temporarily prevents exterior
odours and smoke from entering the
passenger compartment.
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 demisting. This
operating mode is preferable.
This is the preferred operating position.

ERGONOMICS AND COMFORT
Ventilation
Comfort value adjustment ring
The graduation ranges between:
- increasing of the interior ambient air temperature HI (High) which heats to a
maximum graduation of 32,
- cooling of the interior ambient air temperature LO (Low) which cools to a
graduation of 16. or reduce (-) the force of the interior air flow.
Air distribution
Pressing lights the diode on the buttons
which distribute the air flow towards:
the windscreen and front side
window vents (demisting/de-icing
of the windows),
the central and side vents (chest
and face),
the vents in the front and rear
areas (feet).
The combination of buttons permits
improvement of air distribution.
Air flow
Successive presses of this
button increase (+)
Intake of exterior air/recirculation of interior air
When the diode is lit, the air
recirculates inside the passenger
compartment to prevent the entry of exterior
odours and smoke. This position should be
temporary.
When the ambient air comfort level has been
reached, pressing the button switches the
diode off and reopens the exterior air intake.
Pressing the AUTO button also restores
the intake of exterior air. Returning to this
position permits renewal of the air in the
passenger compartment and demisting.
Pressing the AUTO button again restores
the FULL AUTO function.
Rapid demisting/de-icing
Pressing this control permits
rapid clearing of the windows.
The diode is lit.
The system manages the air conditioning,
the flow and intake of air, the de-icing of
the rear screen and provides optimum
distribution of the air to the windscreen and
front side windows.
If your vehicle is fitted with additional
heating, please switch it off to guarantee
rapid and effective demisting/de-icing.

Towing a trailer
ACCESSORIES

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.
On the contrary, use a high gear to lower the
engine speed and reduce your speed.
In all cases, pay attention to the coolant
temperature.
Tyres: check the tyre pressures of the
towing vehicle (see the "Identification
features" section of chapter 9) and of
the trailer, observing the recommended
pressure.
We recommend the use of original
CITROËN towbars and their harnesses,
which have been tested and approved from
the design stage of your vehicle and that
the fitting of this equipment is entrusted to a
CITROËN dealer.
If this equipment is not fitted by a
CITROËN dealer, it is imperative that it is
fitted using the electrical pre-equipment
installed at the rear of the vehicle and
in accordance with the manufacturer ’s
instructions.
Good practice
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning light comes on, stop the
vehicle and switch off the engine
as soon as possible.
See the "Levels" section of chapter 7.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually.

Side wind: sensitivity to side wind
is increased. Drive smoothly and at a
moderate speed.

ABS: the system only controls the vehicle,
not the trailer.

Rear parking assistance: the assistance
does not function while the vehicle is towing.

CHECKS
Levels
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.
Used oil
Avoid prolonged contact of used oil
with the skin.
Brake fluid is harmful to health and very
corrosive.
Do not dispose of used oil, brake fluid or
coolant into drains or into the ground but
into the containers dedicated to this use at
CITROËN dealerships.
Topping up
The level must be between the MIN and MAX
marks on the expansion bottle. If more than
1 litre of fl uid 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 to prevent
freezing, this fluid must not be topped up or
replaced with water.
Capacity of the reservoir: approximately
5.5 litres.
