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 liquid 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 in using the
oil level indicator in the instrument
panel for vehicles equipped with an
electric gauge, or using the dipstick.

Practical information

201
Brake fluid level
The fluid level should be close to the
"MA X" mark. If it is not, check the
brake pad wear.
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.
The check and top-up must only be done with
the engine cold.
A low coolant level presents a
risk of serious
damage to your engine.
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. To avoid the risk of scalding when you need to
top up in an emergency, wrap 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 to the required level.
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
This fluid must conform to the manufacturer's
recommendations.
Screenwash/headlamp
wash level low
In the case of vehicles fitted with
headlamp washers, when the fluid
reser voir low level is reached this
warning lamp comes on in the
instrument panel, accompanied by
an audible signal and a


message.
The warning lamp comes on when the ignition
is switched on, or every time the stalk is
operated, until the reser voir is refilled.
The next time you stop, have the screenwash/
headlamp wash reser voir topped up.
Diesel fuel additive level
(Diesel 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
This additive must be topped up without delay
by a CITROËN dealer or a qualified workshop.
Level of AdBlue
An alert is triggered once the reser ve level is
reached.
To avoid the vehicle being immobilised as per
regulations, you must top up with AdBlue.
For more information on AdBlue and the SCR
system, and, in particular, topping up the tank,
refer to the corresponding section.
When the engine is hot, 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.

Practical information

12 V battery
General points
Lead-acid starter batteries
Batteries contain harmful substances
such as sulphuric acid and lead.
They must be disposed of in
accordance with regulations and must
not, in any circumstances, be discarded
with household waste.
Take used remote control batteries and
vehicle batteries to a
special collection
point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a
well ventilated area and
away from naked flames and sources of
sparks, so as to avoid the risk of explosion
or fire.
Wash your hands afterwards.
Access to the battery
The battery (-) terminal is not accessible.
A remote earth point is located on the upper
part of the bonnet (next to the battery).
Starting using another
battery
When your vehicle's battery is discharged, the
engine can be started using a backup battery
(external or from another vehicle) and jump
leads or a
battery booster.
Never try to start the engine by connecting
a
battery charger.
Never use a
24 V or higher battery
b o o s t e r.
Check beforehand that the backup
battery has a
nominal voltage of 12 V and
a
capacity at least equal to that of the
discharged battery.
The two vehicles must not be in contact
with each other.
Switch off the electrical consumers on
both vehicles (audio system, wipers,
lighting, etc.).
Ensure that the jump lead cables do not
pass close to moving parts of the engine
(cooling fan, belts, etc.).
Do not disconnect the (+) terminal while
the engine is running.
The battery is located under the bonnet.
For access to the (+) terminal:
F

r

elease the bonnet using the interior lever,
then the exterior safety catch,
F

r

aise the bonnet and secure it with its stay,
F

l

ift the plastic cover for access to the (+)
terminal.

Engine technical data and
towed loads
Engines
The engine characteristics are given in the
vehicle's registration document, as well as in
sales brochures.The maximum power corresponds to the
value type-approved on a
test bed, under
conditions defined in European legislation
(Directive 1999/99/EC).
For more information, contact a
CITROËN
dealer or a
qualified workshop.
Weights and towed loads
The weights and towed loads relating to your
vehicle are given in the registration document,
as well as in sales brochures.
These values are also given on the
manufacturer's plate or label.
For more information, contact a CITROËN
dealer or a
qualified workshop. The GTW (Gross Train Weight) and towed load
values indicated are valid up to a
maximum
altitude of 1,000 metres. The towed load value
must be reduced by 10% for each additional
1,000 metres of altitude.
The maximum authorised nose weight
corresponds to the weight permitted on the
towball.
When exterior temperatures are high,
the vehicle per formance may be limited
in order to protect the engine. When the
exterior temperature is higher than 37°C,
limit the towed weight.
Towing using a lightly loaded vehicle can
adversely affect roadholding.
Braking distances are increased when
towing a trailer.
When using a vehicle to tow, never
exceed a speed of approximately 60 mph
(100
km/h) (obser ve the local legislation
in force).
If the exterior temperature is high, it is
recommended that the engine is allowed
to idle for 1
to 2 minutes after the vehicle
comes to a
stop, to facilitate its cooling.
