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

Stop immediately if this light comes
on with the engine running.
Consult a CITROËN dealer.
Engine oil pressure
warning light
This comes on each time the
ignition is switched on until
the engine is started.
If it comes on linked with the STOP
warning light, with the engine running,
this indicates that the oil pressure is
too low.

Stop immediately.
Consult a CITROËN dealer.
Coolant temperature
warning light
This comes on for a few seconds each
time the ignition is switched on.
If this warning light comes on, with
the engine running, this indicates Anti-lock braking
system (ABS) warning
light
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 assistance.
Consult a CITROËN dealer.
Handbrake, low brake
fluid level and braking
system warning light
This comes on each time the ignition
is switched on until the handbrake is
released. Electric power steering
warning light
This comes on for a few seconds 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.
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 scalding,
unscrew the cap 1/4 of a turn
to allow the pressure to drop.
When the pressure has dropped,
remove 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 running,
indicates one of the following:
- that the handbrake 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 light
remains on even with the
handbrake released),
- a braking system fault.

Stop immediately.
Consult a CITROËN dealer.

SAFETY When this warning light
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 lights come on
s i m u l t a n e o u s l y,
it indicates that
there is a malfunc-
tion of the braking system or that the
handbrake 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 light comes on. When a malfunction of the
systems occurs, this warn-
ing light comes on.
The ASR/ESP systems of-
fer exceptional safety dur-
ing normal 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 assembly and operation
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
CHECKS Oil filter
Change the fi lter regularly, in accor-
dance with the servicing schedule. Only use products recom-
mended by CITROËN or
products of equivalent quality
and characteristics.
In order to optimise the op-
eration of units as important as the
braking circuit, 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 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.
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 regu-
larly.
If you drive in dusty conditions,
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 status
For any information relating to disc
and drum surface wear, contact a
CITROËN dealer. Manual gearbox
Have the level checked in accor-
dance with the manufacturer's ser-
vicing 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 pump at least 10 times.
If you run out of fuel, the cir-
cuit must be reprimed:
- fi ll the fuel tank with at least fi ve litres of diesel,
- squeeze and release the manual repriming pump at least 10 times.
This is located under the protective
cover which must fi rst be unclipped
and then removed,
- operate the starter until the en- gine starts.

Notes: if the engine does
not start after approximately
15 seconds of attempts, op-
erate the repriming pump
again approximately fi fteen times be-
fore trying again.
If the emission control warning light has
come on, it will only switch off after your
vehicle has been used several times.
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 the system checked by a
CITROËN dealer.
