List of warning and indicator lamps
Warning/indicator lampState Cause Action/Observations
Red warning/indicator lamps
STOPFixed, associated with another
warning lamp, accompanied
by the display of a message
and an audible signal. Indicates a serious fault with the
engine, braking system, power
steering, automatic gearbox or a
major electrical fault. Carry out (1) and then (2).
Engine oil
pressure Fixed.
There is a fault with the engine oil
lubrication circuit. Carry out (1) and then (2).
Brakes Fixed. The brake fluid level has dropped
significantly. Carry out (1), then top up with brake fluid
that complies with the manufacturer's
recommendations. If the problem persists,
carry out (2).
+ Brakes
Fixed, associated with the
ABS warning lamp. The electronic brake force
distribution (EBFD) system has a
fault. Carry out (1) and then (2).
Parking brake Fixed. The parking brake is applied or not
properly released.
Maximum
coolant
temperature Fixed.
The temperature of the cooling
system is too high. Carry out (1), then wait until the engine
has cooled down before topping up to the
required level if necessary. If the problem
persists, carry out (2).

Because of the presence of electrical
equipment under the bonnet, it is
recommended that exposure to water
(rain, washing, etc.) be limited.
Engines

2. Engine coolant reservoir.

5. Fusebox.
6. A i r f i l t e r.
7. Engine oil dipstick.
8. Engine oil filler cap.
9. Remote earth point.
The Diesel fuel system operates under
very high pressure.
All work on this circuit must be carried out
only by a CITROËN dealer or a qualified
workshop.
Checking levels
Check all of these levels regularly, in line with
the manufacturer's service schedule. Top them
up if necessary, unless other wise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluid must comply with the
manufacturer's recommendations and with
the vehicle's engine. Take care when working under the bonnet,
as certain areas of the engine may be
extremely hot (risk of burns) and the
cooling fan could start at any time (even
with the ignition off).
Used products
Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to health
or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop and dispose of
it in the containers reser ved for this
purpose.
Engine oil level
The check is carried out either when
the ignition is switched on using the
oil level indicator in the instrument
panel for vehicles equipped with an
electric gauge, or using the dipstick.
Practical information

146
Brake fluid level
The fluid level should be close to the
"MA X" mark. If it is not, check the
brake pad wear.
Brake fluid change
Refer to the manufacturer's service schedule
for details of the inter val for this operation.
Fluid specification
The fluid must conform to the manufacturer's
recommendations.
Coolant level
Check the coolant level regularly.
It is normal to top up the fluid
between two services.
To ensure that the reading is correct, your
vehicle must be parked on a level sur face with
the engine cool. When the engine is warm, the temperature of
the coolant is regulated by the fan.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying out any
work.
To avoid the risk of scalding when you need to
top up in an emergency, place a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the
cap and top up the coolant.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might be
caught by the fan blades.Fluid specification
The fluid must conform to the manufacturer's
recommendations.
The coolant level should be close to the "MA X"
mark but should never exceed it.
If the level is close to or below the "MIN" mark,
it is essential to top up.
A low coolant level presents a risk of serious
damage to your engine.
Screenwash fluid level
Top up the level when necessary.
Fluid specification
The screenwash fluid must be topped up with a
ready for use mix.
In winter (temperatures below zero), a fluid with
antifreeze must be used that is appropriate for
the prevailing conditions, in order to preser ve
the elements of the system (pump, tank, ducts,
e t c .) .
Filling with pure water is prohibited under all
circumstances (risk of freezing, limestone
deposits, etc.).
Diesel additive level (Diesel
engine with particle filter)
The additive reser voir low level is
indicated by fixed illumination of this
warning lamp, accompanied by an
audible signal and a message that
the particle filter additive level is
too low.
To p p i n g u p
The reser voir must be topped up without delay
by a CITROËN dealer or a qualified workshop.
Practical information

148
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed
of at least 37 mph (60 km/h) until the
warning lamp goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.
For more information on Checking the
levels and particularly on the level of
Diesel additive, refer to the corresponding
section.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell, which
is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at the
exhaust on acceleration. This does not
affect the behaviour of the vehicle or the
environment.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Electronic gearbox
The gearbox does not require any
maintenance (no oil change).
Brake pads
Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to
have the condition of the brakes
checked, even between vehicle
services.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Brake disc/drum wear
For information on checking brake
disc/drum wear, contact a CITROËN
dealer or a qualified workshop.
Parking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must
be checked, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units
as important as those in the braking
system, CITROËN selects and offers very
specific products.
After washing the vehicle, dampness, or
in wintry conditions, ice can form on the
brake discs and pads: braking efficiency
may be reduced. Make light brake
applications to dry and defrost the brakes.
