Good practice
The ABS system does not provide shorter
braking distances. On very slippery surfaces
(black ice, oil...) the ABS can extend braking
distances. For emergency braking, press the
brake pedal hard and do not release it, even
on a slipper surface; you will then be able to
steer the vehicle and avoid an obstacle.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.Emergency braking assistance
System which, in an emergency, enables
you to obtain the optimum braking pressure
more quickly, thus reducing the stopping
distance.
Operation
It is triggered by the speed at which the
brake pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase in
braking efficiency.
Switching off
This system cannot be deactivated by
the driver.
Operating fault
If this warning lamp comes on,
accompanied by an audible signal
and a message in the instrument
panel screen, it indicates a fault with
the anti-lock braking system which could result in
loss of control of the vehicle when braking.
For maximum braking efficiency, a
bedding-in period of around 300 miles
(500 kilometres) is needed. During this
period it is recommended that you avoid
harsh, repeated or prolonged braking. If this warning lamp comes on,
together with the ABS warning
lamp, accompanied by a message
in the instrument panel screen,
it indicates a fault with the electronic brake
force distribution which could result in loss
of control of the vehicle when braking. When braking in an emergency, press
firmly without releasing the pressure.
You must stop as soon as it is safe to do so.
In either case, contact a CITROËN dealer or
a qualified workshop.

cooling system
Check the coolant level regularly,
according to the use made of your
vehicle (every 3 000 miles or 5 000 kms
/
3

months);
if necessary, top-up using coolant
recommended by the manufacturer.
Topping-up the coolant between services is
normal.
The check and top-up must be done with the
engine cold.
A low coolant level presents the risk of
serious damage to your engine. For access to the header tank filler cap,
remove the protective cover by turning its
three fixing screws a quarter turn.
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 the risk of scalding, with a cloth
around the cap, slacken the cap by a quarter
turn to release the pressure. When the
pressure has dropped, remove the cap and
top-up the level with coolant.changing the brake fluid
The brake fluid must be changed at
the intervals stated, according to the
manufacturer's service schedule.
Use brake fluid recommended by the
manufacturer, meeting the DOT4 standard.
The level must be between the MI
n and
MA
x marks on the reservoir.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer or a qualified workshop
as soon as possible. Engine oil grade
When topping-up, the oil selected must meet
the manufacturer's requirements. Oil change
It is imperative that this is carried out at the
intervals specified in the manufacturer's
service schedule. Ask for advice from a
CITROËN dealer.
Refill the engine oil using the procedure
described for topping-up.
Check the level after filling (never exceed
the maximum mark).
Levels and checks

Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
In order to avoid damaging the
electrical units, we strongly advise you
not to use high pressure washing to clean
the engine compartment.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes. 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.
diesel fuel filter
The Diesel fuel filter is located under the
bonnet, close to the brake fluid reservoir.
If this warning lamp comes on, the
filter must be bled to remove water.
Y

ou can also bleed the fuel filter
regularly, every time the engine oil
is changed.
Bleeding water from the filter
-

Connect a transparent pipe to the head

of the bleed screw 1 .
-

Place the other end of the transparent

pipe in a recipient.
-

Slacken the bleed screw

technology. All work must be done by

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 the whole system checked by a
CITROËN dealer or a qualified workshop.
If there is risk of blockage of the
filter, this warning lamp comes on
in the instrument panel.
Saturation /
r
egeneration
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.
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.
Operation
This filter, fitted in the exhaust system,
accumulates particles of soot. The engine
management unit controls 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. 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.
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.)
