Instruments and controls
FUEL GAUGE
The fuel level is tested each time the key is
turned to the "ignition on" position.
The gauge is positioned on:
- F (full): the capacity of the fuel tank is
approximately 45 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 6 litres. 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 approximately 15 minutes to allow
the engine to cool down in order to check
the level and top it up if necessary. 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. EMISSION CONTROL
EOBD (European On Board Diagnosis) is a
diagnostics system which meets the exhaust
emissions standards for:
- CO (carbon monoxide),
- HC (unburnt hydrocarbons),
- NOx (nitrous oxides) or particles detected by oxygen sensors placed upstream and
downstream of the catalytic converters.
Refer to the "Levels" section of
chapter 7. Refer to the "Levels" section of chapter 7.
The driver is warned of any
fault with this emission control
system by flashing of this specific
warning lamp in the instrument
panel.

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 cooling fan may continue to operate
for a certain time up to approximately
10 minutes.

Towing a trailer
TOWING A TRAILER, CARAVAN, ETC...
Driving advice 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.
A towed vehicle must free wheel: gearbox in
neutral.

Cooling: towing a trailer on a slope
increases the coolant temperature.

Levels
Engine coolant level
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 cooling 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.
Topping up
The level must be between the MIN and

MAX marks on the header tank. If more than
1 litre of fluid is required to top up the level,
have the system checked by a CITROËN
dealer. Power steering fluid level
The vehicle must be parked on level ground
with the engine cold. Unscrew the cap with
integral gauge and check the level which
must be between the
MIN and MAX marks.
Screenwash fluid level
For optimum cleaning and to avoid freezing,
topping up or replacement of this fluid
should never be with plain water; we
recommend the use of products available
from CITROËN dealers.
Capacity of the reservoir: approximately
5.5 litres.
Slacken the cap by two turns 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 fault which must be checked by a
CITROËN dealer as soon as possible. Used products
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 provided for this
purpose at CITROËN dealers (France) or
at an authorised waste disposal site.

Checks
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the Warranty and Maintenance
Record for the details of the level checking
interval for this component.
To check the main levels and certain
components, in accordance with the
manufacturer's servicing schedule, refer to
the pages of the servicing booklet which
correspond to your vehicle's engine.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
In order to avoid damaging the electrical
units, high pressure washing to clean the
engine compartment is strictly prohibited. Particle filter system (1.3 HDi 75)
An addition to the catalytic converter, this
fi lter 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 fi lter, fi tted 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.
Saturation/Regeneration
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.
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.
Electronic gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the servicing booklet for details of
the checking interval for this component.
Because of the higher exhaust
gas temperature resulting from the
normal operation of the particle fi lter, it is
recommended that you do not park the vehicle
over infl ammable materials (grass, dry leaves,
pine needles, ...) so as to avoid any risk of fi re.
