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
Intake of exterior air
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.

T
Ventilation
Comfort value adjustment ring
The settings range between:


- increasing the interior ambient air
temperature HI (High) which goes up to
to a maximum setting of 32,

- cooling the interior ambient air
temperature LO (Low) which goes down
to a setting of 16.

Air distribution

A press illuminates the LED on the buttons
which distribute the air flow towards:
the windscreen and front side
window vents (demisting/
defrosting 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 (+) or reduce (-) the
force of the air flow to the interior.


Intake of exterior air/
recirculation of interior air
When the LED is on, 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
LED 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/defrosting

Pressing this control permits
rapid clearing of the windows.
The LED is on.
The system manages the air conditioning,
the flow and intake of air, the defrosting
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, switch it off to ensure rapid and
effective demisting/defrosting.
ADDITIONAL REAR VENTILATION


The controls for this system,
additional to the standard cabin
ventilation system, are on the
lower dashboard, to the right of
the steering wheel.

Air outlet
A press on this control activates
the extraction of air to the
outside; the LED comes on.
Press again to switch off.

Air inlet
A press on this control activates
the entry of air into the cabin; the
LED comes on. Press again to
switch off.

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.

Checks

Particle filter system (Diesel)

An addition to the catalytic converter, this
filter makes an active contribution to the
preservation of air quality by the retaining
of the unburnt pollutant particles. Black
exhaust fumes are thus no longer emitted.
This filter, fitted to the exhaust system,
accumulates particles of soot. The engine
control unit manages the automatic
periodic elimination of the soot particles
(regeneration).
The regeneration procedure is invoked
according to the quantity of particles
accumulated and the driving conditions
of the vehicle. During this phase, you
may notice some unusual phenomena -
increased idling speed, cooling fan running,
increase in smoke and higher exhaust gas
temperature - which does not affect the
operation of the vehicle or the environment. After prolonged idling or driving at very low
speeds, you may occasionally notice water
vapour being emitted from the exhaust when
accelerating. This is of no consequence
to the running of the vehicle or to the
environment.
Because of the higher exhaust gas
temperature resulting from the normal
operation of the particle filter, it is
recommended that you do not park the
vehicle over inflammable materials (grass,
dry leaves, pine needles, ...) so as to avoid
any risk of fire.
Saturation / Regeneration

Operating fault
If this alert persists, do not ignore the
warning; it indicates that a fault has occurred
in the exhaust / particle filter system.
Have it checked by a CITROËN dealer.
If there is risk of blockage of the
filter, this warning lamp comes on
in the instrument panel.
This alert tells you that the particle filter
is starting to fill up (in conditions of urban
driving of exceptionally long duration: low
speeds, traffic jams etc.)
To regenerate the filter, it is advised to drive
as soon as possible, when traffic conditions
and the law permit, at a speed of at least
40 mph (around 60 km/h), with an engine
speed above 2 000 rpm for about fifteen
minutes (until the warning lamp and/or the
message disappears).
If possible, avoid switching off the engine
before the end of regeneration of the
filter; repeated interruptions could cause
premature deterioration of the engine oil. It
is not recommended to end regeneration of
the filter with the vehicle stationary.
