Instruments and controls
SERVICE INDICATOR
The display on the instrument panel
informs you when the next service is due,
in accordance with the "Manufacturer's"
servicing schedule indicated in the servicing
booklet. This information is determined in
relation to the distance travelled since the
previous service. You are warned by flashing of the
engine oil pressure warning light
and the displaying of a message
on the instrument panel each time
the vehicle is started.

In this case, your vehicle must be
serviced as soon as possible.
LIGHTING RHEOSTAT
The rheostat is active when the lights are on.
Refer to the list of checks in the
servicing booklet which was given to
you on delivery of the vehicle.
After a few seconds, the display returns to
its usual functions. Use the + and - controls to
change the brightness of the
instrument panel lighting.

SAFETY
Driving safety
HORN
Press the centre of the steering wheel.
ABS ANTI-LOCK BRAKING SYSTEM
The ABS increases the stability and
manoeuvrability of your vehicle when
braking, particularly on poor or slippery road
surfaces.

Note: when changing wheels (tyres and
rims), make sure that they conform to the
manufacturer's recommendations.
The anti-lock braking system comes into
operation automatically when there is a risk
of wheel lock.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.

In emergency braking, press very firmly
without releasing the pressure.
Good practice
The anti-lock braking system comes into
operation automatically when there is a risk
of wheel lock. It does not permit shorter
braking. On very slippery road surfaces
(ice, oil, etc...) the ABS may lengthen the
braking distances. In emergency braking,
do not hesitate to press the brake pedal
firmly, without releasing the pressure, even
on slippery roads, you will then be able to
continue to manoeuvre the vehicle to avoid
an obstacle.
If the ABS warning light on the
instrument panel comes on, this
indicates a malfunction of the anti-
lock braking system which could
result in a loss of control of the vehicle on
braking.

Stop immediately.
Consult a CITROËN dealer.

TROUBLESHOOTING
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. 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 dealership.
Slacken the cap by two turns to release the
pressure to prevent any risk of scalding.
When the pressure has dropped, 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.

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 fi lter 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.
