INSTRUMENTS and CONTROLS
WARNING LAMPS AND INDICATORS
Central STOP
warning lamp
This fl ashes for a few
seconds each time the ignition is
switched on. It is linked with the
warnings for:
- "engine oil pressure",
- "coolant temperature".

Stop immediately if this
lamp
comes
on with the engine running.
Consult a CITROËN dealer.
Engine oil pressure
warning lamp
This comes on each time the
ignition is switched on until
the engine is started.

If it comes on linked with the STOP
warning lamp, with the engine running,
this indicates that the oil pressure is too
low.

Stop immediately.
Consult a CITROËN dealer.
Coolant temperature
warning lamp
This comes on for a few
seconds each time the ignition is
switched on. Anti-lock braking
system (ABS) warning
lamp
This comes on for a few seconds
each time the ignition is switched on.
Fixed lighting indicates a malfunction
of the ABS.
However, the vehicle retains conven-
tional braking with servo-assistance.
Consult a CITROËN dealer.
Parking brake, low
brake fluid level
and braking system
warning lamp
This comes on each time the ignition
is switched on until the parking brake
is released. Electric power steering
warning lamp
This comes on for a few sec-
onds each time the ignition is
switched on.
Fixed lighting, when the vehicle is
moving, indicates a malfunction of
the electric steering system.
Consult a CITROËN dealer.
If this warning lampcomes on, with
the engine running, this indicates
an abnormal increase in the coolant
temperature.

Stop immediately .
Check the coolant level.
To do this, wait until the engine has
cooled before topping up the level.
The cooling system is pressurised.
When checking the level, and
to avoid any risk of scald-
ing, unscrew the cap 1/4 of
a turn to allow the pressure
to drop.
When the pressure has dropped, re-
move the cap.
Then:

1. top up, if necessary
(see "Levels").

2. or, if the level is satisfactory,
contact a CITROËN dealer. Fixed lighting, with the engine run-
ning, indicates one of the following:
- that the parking brake is applied
or has not been released fully,
when the vehicle is moving,
- an excessive drop in the brake fl uid level (if the warning lamp
remains on even with the parking
brake released),
- a braking system fault.

Stop immediately.
Consult a CITROËN dealer.

COMFORT
VENTILATION
Recommendations for
use
If the interior temperature
remains very high after a prolonged
period parked in the sun, fi rst venti-
late the passenger compartment for
a few minutes.
For an even air distribution, make
sure that you do not block the out-
side air inlet grille, the vents, the air
passages and the air outlets to the
footwells.
Ensure that the passenger compart-
ment fi lter, located below the wind-
screen, in the engine compartment,
is in good condition. Have the fi lter
elements replaced regularly. If you
drive in dusty conditions, change
them twice as often.
Operate the air conditioning system
for 5 to 10 minutes, once or twice a
month, to keep it in perfect working
order.
In order to ensure that your air condi-
tioning system continues to operate
correctly, you are advised to have it
checked regularly.
The condensation created by the air
conditioning results in a fl ow of wa-
ter under the vehicle when stationary
which is perfectly normal.
If the system does not produce
cold air, do not use it and contact a
CITROËN dealer.

3. Side vents.

4. Diffusion grille.

5. Air outlets to the footwells.

1. Windscreen demisting/defrosting
vent.

2. Side window demisting/
defrosting vents.
The air conditioning system
does not contain chlorine
and does not present any
danger to the ozone layer.

SAFETY When this warning lamp
comes on, it indicates that
there is a malfunction of the
ABS, which can cause a
loss of control of the vehicle
when braking.
Consult a CITROËN dealer.
When these warn-
ing lamps come
on simultaneous-
ly, it indicates that
there is a malfunc-
tion of the braking system or that the
parking brake has not been released
fully, which can cause a loss of con-
trol of the vehicle when braking.

Stop immediately.
Consult a CITROËN dealer.
Normal operation of the ABS
may make itself felt by slight
vibrations of the brake pedal.

In emergency braking,
press very fi rmly without
releasing the pressure. TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
These systems are linked and sup-
plement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by act-
ing on the brakes of the driving wheels
and on the engine. It also allows the
directional stability of the vehicle to
be improved on acceleration.
If there is a variation between the tra-
jectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
brake of one or more wheels and on
the engine to put the vehicle back on
course, within the limits of the laws
of physics.
Operating check
Operation of the ASR and ESP
systems When one of these two
systems is operating, this
warning lamp comes on. When a malfunction of the
systems occurs, this warn-
ing lamp comes on.
The ASR/ESP systems offer
exceptional safety during nor-
mal driving, but this should
not encourage the driver to
take extra risks or drive at
high speed.
Correct operation of these systems
depends on observation of the man-
ufacturer's recommendations re-
garding the wheels (tyres and rims),
the braking components and the
electronic components as well as the
CITROËN dealer repair procedures.
After an impact, have these systems
checked by a CITROËN dealer.
Activation of the ESP system is also
accompanied by an audible signal. Contact a CITROËN dealer to have
the systems checked.

CHECKS
CHECKING THE LEVELS
There are two marks
on the dipstick:

A = maximum
If you fi ll past this mark,
contact a CITROËN
dealer.

B = minimum
Never allow the level
to fall below this mark.
Dipstick
Oil change
According to the information given in
the servicing booklet. Changing the brake fluid
The brake fl uid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fl uids recommended by the
manufacturer, which fulfi l DOT4
standards.
Windscreen wash level
For best quality cleaning and for your
safety, we would advise that you
use products recommended by your
manufacturer.
Consult a CITROËN dealer.
Oil viscosity grade
In all cases, the oil selected must meet
the manufacturer's requirements. Cooling system
Used oil
Avoid prolonged contact of used oil
with the skin.
Brake fl uid is harmful to health and
very corrosive.
To maintain the reliability of
engines and emission control
systems, the use of additives
in engine oil is prohibited. Slacken the cap by 1/4 of a
turn to release the pressure
to prevent any risk of scald-
ing. When the pressure has
dropped, remove the cap and top up
the level. Only use the fl uid recom-
mended by the manufacturer.
Otherwise, you risk seriously
damaging your engine.
Do not dispose of used oil,
brake fl uid or coolant into
drains or into the ground.
Empty the used oil into the
containers provided for this
purpose in the CITROËN network
(France) or at an authorised waste
disposal site.
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.
When the engine is warm, the tem-
perature 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.

ance with the servicing schedule. Only use products recom-
mended by CITROËN or
products of equivalent qual-
ity and specifi cation.
In order to optimise the
operation of units as important as the
braking system, CITROËN selects
and offers specifi c products.
In order to avoid damaging the elec-
trical units, high pressure washing
to clean the engine compartment is
strictly prohibited.
To check the main levels and cer-
tain components, in accordance with
the manufacturer's servicing sched-
ule, refer to the pages of the Main-
tenance and Warranty Guide which
correspond to your vehicle's engine.
Battery
At the start of winter, have your bat-
tery checked by a CITROËN dealer.
Air filter and passenger
compartment filter
Have the fi lter elements replaced reg-
ularly.
If you drive in dusty condi-
tions, change them twice as often.
Brake pads
Brake pad wear depends on the style
of driving, in particular for vehicles
which are used in town, over short
distances.
Disc and drum wear
For any information relating to disc
and drum surface wear, contact a
CITROEN dealer. Manual gearbox
Have the level checked in accord-
ance with the manufacturer's servicing
schedule.
RUNNING OUT OF FUEL (DIESEL)
It may be necessary to check
the thickness of the pads,
even between services.
If the engine stops, it is pos-
sible to restart it to drive a
short distance by operating
the priming pump at least
10 times.
If you run out of fuel, the circuit must
be reprimed:
- fi ll the fuel tank with at least fi ve litres of diesel,
- squeeze and release the manual priming pump at least 10 times.
This is located under the protec-
tive cover which must fi rst be un-
clipped and then removed,
- operate the starter until the en- gine starts.

Notes: if the engine does
not start after approximate-
ly 15 seconds, operate the
priming pump again approxi-
mately fi fteen times before trying
again.
If the emission control warning lamp
has come on, it will only switch off af-
ter your vehicle has been used sev-
eral times.
Parking brake
Where the parking brake travel is too
great or there is a reduction in the
performance of the system, the park-
ing brake should be adjusted, even
between services.
Have the system checked by a
CITROËN dealer.
