WARNING LAMPS

Every time the engine is started: a series of warning lamps comes on, applying a self-checking test. They go off almost
immediately. When the engine is running: a warning lamp becomes a warning sign if it remains on continuously or flashes. This
initial warning may be accompanied by an audible signal and a message in the screen. "Do not ignore these warnings."

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 lamp 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 lamp
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 lamp on the
instrument panel.
There is a risk of damage to the catalytic
converter. Have it checked by a CITROËN dealer.

Ventilation

ADDITIONAL HEATING SYSTEMS
Supplementar
y heating
On the 2-3 seats version, this is located
under the seat on the driver's side with air
diffusion directed forwards.
REAR HEATING AND/OR AIR
CONDITIONING
If your vehicle is fitted with an
additional air conditioning unit,
located in the rear of the vehicle:
the distribution duct located in
the roof and the individual diffusion vents
provide a perfect diffusion of cold air.
The warm air diffused at the floor, from the
front air conditioning unit, is distributed at
the feet of the rear passengers of rows 2
and 3.
A warm air diffusion vent, located on the rear
left wheelarch, may complete the assembly
for the feet of the rear passengers of row 3.

Additional heating

This is passenger compartment heating,
additional to the standard equipment.
It can operate independently of the engine.


Additional heater or programmable
additional heating
This is an additional, programmable and
separate system which heats the Diesel
engine hot coolant loop to make starting
easier.
It improves the demisting and defrosting
performance and that of the heated seats, if
fitted to the vehicle.
The passenger compartment heating is
brought up to temperature more rapidly.
This system must be programmed to start up
before you enter the vehicle. On the 5-9 seats version, it is
located at the rear. Depending
on the model version, the air
diffusion is either direct from the
rear or comes from the rail located under
each of the two rows of seats.
Press this control to activate/
deactivate the heating. The LED
is on if the heating is activated.
When rapid demisting and
defrosting is required, switch off the control.

Cancelling the programming

Press this button briefly to clear
the programmed start time.
The screen illumination and the
pre-selection number (e.g. 1) are
switched off.
Good practice

To avoid any risk of poisoning or
asphyxiation, the additional heating must
not be used, even for short periods, in
an enclosed space such as a garage or
workshop which is not fitted with an exhaust
gas extraction system.
The additional heating is supplied by the
vehicle's fuel tank.
Ensure that the fuel gauge indicator lamp is
not at reserve.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire.
The temperature near the heater must not
exceed 120 °C. A temperature higher than
this (for example in the case of painting in
an oven) could damage the components of
the electronic circuits.
The additional heating system is fitted with
a temperature limiter which cuts off the
combustion in the event of overheating due
to a lack of coolant.
Top up the coolant, then press the
programme selection control before
switching the heating on again. Have the additional heating system
checked at least once a year at the
beginning of winter. Maintenance and
repairs should only be carried out by a
CITROËN dealer.
Use only genuine replacement parts.


Recalling one of the pre-selected
start times

Press this button as many times
as necessary until the number
corresponding to the required pre-
selected start time (e.g. 2) appears.
After ten seconds, the time is cleared but
remains stored for as long as the number
(e.g. 2) and the screen remain on.


Switching off the heating

Press this button.
The heating cycle indicator lamp
and the screen are switched off.


Two different types of equipment

The additional heating is separate and
programmable. Before you enter the vehicle,
it gradually increases the temperature of the
engine to make starting easier.
This also facilitates passenger compartment
heating, demisting and defrosting.
The additional passenger compartment
heating system supplements the
standard equipment. Its operation may be
independent of the engine.
Switching on of the heating may be
programmable.

Towing a trailer

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
markings" section of chapter 9) and of
the trailer, observing the recommended
pressures.
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 lamp 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 sensors:
the system does not
operate while the vehicle is towing.

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 (France) or to an
authorised waste disposal site.


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 to prevent
freezing, this fluid must not be topped up or
replaced with plain water.
Capacity of the reservoir: approximately
5.5 litres.
