g
lamp, keeping your foot on the brake pedal.
Observe the safety recommendations.
For further information on the parking brake, refer
to the "Safety" section.
STOP fi x e d , a s s o c i a t e d
with another
warning lamp. It is associated with
the engine oil pressure
or the engine coolant
temperature. Stop as soon as it is safe to do so.
Park, switch off the ignition and call a CITROËN

MONITORING
Anti-lock
Braking
System (ABS) fi x e d .
The anti-lock braking
system has a fault. The vehicle retains conventional braking.
Drive carefully at reduced speed and contact a

programme (
ASR
/
ESP
) fi x e d .
The ASR/ESP system is
in action. The system optimises traction and improves
the directional stability of the vehicle.
fi x e d .
The ASR/ESP system
has a fault. Have it checked by a CITROËN dealer or a
q u a l i fi e d w o r k s h o p .
Coolant
temperature fi x e d . The temperature of the
engine coolant is too
high. Stop as soon as it is safe to do so.
Wait until the engine has cooled down before
checking up the level; top up if necessary.
If the problem persists, contact a CITROËN
d e a l e r o r q u a l i fi e d w o r k s h o p .
Airbags temporarily.
This lamp comes on for
a few seconds when you
turn on the ignition, then
goes off. This lamp should go off when the engine is
started.
If it does not go off, contact a CITROËN dealer
o r a q u a l i fi e d w o r k s h o p .
fl a s h i n g . At least one of the
airbags has a fault. The airbags may not be deployed in the event of
a serious impact. Have it checked by a CITROËN

COMFORT
VENTILATION
Recommendations for use
If the interior temperature re-
mains very high after a pro-
l o n g e d p e r i o d p a r k e d i n t h e s u n , fi r s t
ventilate 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-
m e n t fi l t e r , l o c a t e d b e l o w t h e w i n d -
screen, in the engine compartment,
i s i n g o o d c o n d i t i o n . H a v e t h e fi l t e r
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

which is perfectly normal.
If the system does not produce
cold air, do not use it and contact a

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 fault with the ABS,
which could cause a loss of
control of the vehicle when
braking.
Contact a CITROËN dealer or a
q u a l i fi e d w o r k s h o p .
When these warn-
ing lamps come on
simultaneously, it
indicates that there
is a fault with the braking system or
that the parking brake has not been
released fully, which can cause a
loss of control of the vehicle when
braking.
You must stop as soon as it is safe
to do so.
Contact a CITROËN dealer or a
q u a l i fi e d w o r k s h o p .
Normal operation of the ABS
may make itself felt by slight
vibrations of the brake pedal.
In emergency braking,
p r e s s v e r y fi r m l y w i t h o u t

Operating check
Operation of the ASR and ESP
systems
When one of these two sys-
tems is operating, this warning
lamp comes on.
If a fault occurs with the
systems, this warning 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 manu-
facturer's recommendations regarding
the wheels (tyres and rims), the brak-
ing components and the electronic
components as well as the repair pro-
cedures use by a CITROËN dealer or
q u a l i fi e d w o r k s h o p .
After an impact, have these systems
checked by a CITROËN dealer or a

tems checked.
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.

Otherwise, you risk seriously
damaging your engine.
Do not dispose of used oil,
b r a k e fl u i d o r c o o l a n t i n t o
drains or into the ground.
Empty the used oil into the
containers provided for this
purpose in the CITROËN dealer

(France) or at an authorised waste
disposal site.
Oil level
Check the level regularly and top up
between changes. The maximum oil
consumption is 0.5 litre per 600 miles
(1 000 km).
Check the level with the vehicle level,
engine cold, using the dipstick.
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.

PRACTICAL INFORMATION
BATTERY
Do not push the vehicle to
start the engine if you have a
"SensoDrive" gearbox.
Before disconnecting the
battery, you must wait for
2 minutes after switching off
the ignition.
Starting the vehicle from
another battery
- Connect the red cable to the positive
(+) terminals of the two batteries,
- connect the green or black cable to the negative (-) terminals of the two
batteries,
- operate the starter, let the engine run,
- wait for the engine to return to idle, then disconnect the cables.
It is advisable to disconnect
the battery if the vehicle is
not to be used for a period of
more than one month.
The batteries contain harm-
ful substances such as sul-
phuric acid and lead. They
must be discarded in accor-
dance with the provisions of the law
and must not, in any circumstances,
be discarded with household waste.
Take used batteries to an authorised
waste disposal site.
Charging the battery using
a battery charger
- Disconnect the battery,
- follow the instructions for use
given by the battery charger
manufacturer,
- reconnect starting with the negative (-) terminal,
- check that the terminals and connectors are clean. If they are
covered with sulphate (white or
greenish deposit), disconnect
them and clean them.
A. Failed battery
B. Slave battery Never disconnect a terminal when
the engine is running.
N e v e r c h a r g e a b a t t e r y w i t h o u t fi r s t
disconnecting the terminals.
Close the windows and doors before
disconnecting the battery.
After every reconnection of the bat-
tery, switch on the ignition and wait
1 minute before starting to allow the
electronic systems to be initialised. If
s o m e d i f fi c u l t i e s a r e e x p e r i e n c e d a f -
