Having your vehicle towed
BEING TOWED
Without lifting (four wheels on the ground)
You must always use a towbar.
From the front
The removable towing eye is located in the
tool kit behind the driver ’s seat (Van) or
behind the rear benchseat (Combi).
Unclip the cover using a flat tool.
Screw the removable towing eye in fully.
From the rear
Hook the bar onto the rigid eye located
under the bumper.
With lifting (2 wheels only on the ground)
It is preferable to lift the vehicle using
professional lifting equipment.
When being towed with the engine
off, there is no braking or steering
assistance.

122
Fuel
FILLING WITH FUEL
Low fuel level
When the minimum fuel tank
level is reached, this warning
light comes on. At this moment,
you have approximately 6 litres
remaining. Fill up without delay to avoid
running out of fuel.
The fuel tank must be filled with the engine
off .
- Open the fuel filler flap.
- Hold the cap with one hand.
- With the other hand, insert the key and turn it a third of a turn.
- Remove the cap. When the fuel filler flap is open, a
safety system prevents sliding of the
side door.
A label affixed to the inside of the flap
reminds you of the type of fuel to be used.
When filling the fuel tank, do not continue
after the 3rd cut-off of the nozzle. This could
cause malfunctions.
The capacity of the fuel tank is
approximately 45 litres.
After filling the fuel tank, lock the cap and
close the flap.
FUEL CIRCUIT DEACTIVATED
In the event of a serious collision, a device
automatically cuts off the fuel supply to the
engine and the vehicle’s electrical supply.
This also automatically unlocks the doors
and switches on the interior lights.
A message is displayed on the instrument
panel (depending on model).
Turn the key to position STOP to avoid the
battery being discharged.

Check that there is no smell or leak of fuel
outside the vehicle.
Reactivating
To continue driving, manually re-establish
the fuel supply and the electrical supply:
- with the ignition key in position STOP,
turn it to position RUNNING,
- move the direction indicators control stalk all the way upwards,
- put it to position "Stop",
- move the direction indicators control stalk all the way downwards,
- put it to position "Stop" again,
- move it all the way upwards again,
- put it to position "Stop" again,
- move it all the way downwards again,
- put it to position "Stop" again,
- turn the ignition key to position STOP.

TROUBLESHOOTING
Levels
These regular maintenance operations
will keep your vehicle in good
running order. Consult the instructions at a
CITROËN dealer or in the servicing booklet
enclosed in the handbook pack.
LEVELS

Oil level
Check the level regularly and top up
between changes. The maximum
consumption is 0.5 l per 600 miles
(1 000 km). Check the level with the vehicle
level, engine cold, using the dipstick.

Dipstick
There are two marks on the
dipstick:
A = maximum
If you fill past this mark,
consult a CITROËN dealer .
B = minimum
Never allow the level to fall
below this mark.
To maintain the reliability of engines and
emission control systems, the use of
additives in engine oil is prohibited.
Oil change
It is imperative that this is carried out at the
intervals specified and the viscosity grade of
the oil selected must fulfil the requirements
in accordance with the manufacturer ’s
servicing schedule. Consult the instructions
at a CITROËN dealer .
Remove the dipstick before filling.
Check the level after filling (never exceed
the maximum mark).
Screw the cap back onto the sump before
closing the bonnet.
Changing the brake fluid
The brake fluid must be changed at
the intervals stated, according to the
manufacturer ’s servicing schedule.
Use fluids recommended by the
manufacturer, which fulfil DOT4 standards.
The level must be between the MIN and

MAX marks on the reservoir.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer as soon as possible.

Warning lights
Checking by means of the warning
lights on the instrument panel is
described in chapter 1, refer to the
"Instruments and controls" section.

128
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.
To avoid any risk of burns, unscrew the cap
2 turns to release the pressure. When the
pressure has fallen, 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.
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 .

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.

Windscreen 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 reservoir: approximately
5.5 litres.
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 a
CITROËN dealer .

Checks
CHECKS

Bleeding the water contained in the
diesel filter
If this warning light comes on,
bleed the filter, otherwise bleed
regularly each time the engine is
drained.
To evacuate the water, unscrew the bleed
screw or the water in diesel sensor, located
at the base of the filter. Operate until all
of the water has been drained out. Then
tighten the bleed screw or the water sensor.
HDi engines use advanced technology. All
work requires a special qualification which is
guaranteed by a CITROËN dealer .

Battery
At the start of winter, have it checked by a
CITROËN dealer .
Air filter and passenger compartment
filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are indicated
in the servicing booklet.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary, refer to the "Under the
bonnet" section of chapter 7.

Brake pads
Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Unless there is a leak on the circuit, a drop
in the brake fluid level indicates that the
brake pads are worn.

Brake disc/drum wear status
For any information relating to checking
the brake disc/drum wear status, consult a
CITROËN dealer .
Handbrake
Where the handbrake travel is too great
or there is a reduction in the performance
of the system, the handbrake should be
adjusted, even between services.
Have it checked by a CITROËN dealer .

Oil filter
Change the filter regularly, in accordance
with the servicing schedule.
Manual gearbox
Have the level checked in accordance with
the manufacturer ’s servicing schedule.
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 characteristics.
In order to optimise the operation of units as
important as the braking circuit, 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.
