Brake disc wear
For information on checking brake
disc wear, contact a CITROËN or
a


qualified workshop.
Parking brake
If excessive travel or a loss of
e ffectiveness 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.
Diesel fuel filter
The Diesel fuel filter is located under the
bonnet, close to the brake fluid reser voir. If this warning lamp comes on, the
filter must be purged to remove
water.
You can also purge the fuel filter
regularly, every time the engine oil
is changed.
Purging water from the filterThe HDi engines use advanced technology.
All work must be done by personnel that
have had special training, which can be
ensured by going to 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
components 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.

Practical information

Keep AdBlue® out of the reach of children,
in its original container or bottle.
Never transfer AdBlue
® to another
container: it would lose its purity.
Never dilute AdBlue
® with water.
Never pour AdBlue® into the Diesel fuel
tank.
Bottles or containers are available from
a

CITROËN dealer or a

qualified workshop.
Recommendations on storage
AdBlue® freezes at about -11°C and
deteriorates above 25°C. It should be stored in
a

cool place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a
year.
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
Never store bottles or containers of
AdBlue
® in your vehicle.
Procedure
In cold weather, before per forming the top up
ensure that the temperature of the vehicle is
above -11°C. Other wise the AdBlue
® may be
frozen and so cannot be poured into its tank.
Park your vehicle in a

warmer area for a few
hours to allow the top up to be carried out.
Use only AdBlue
® fluid that meets the
ISO

22241

standard.

Starting using another
battery
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 all the electrical consumers
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are not
close to moving parts of the engine (fan,
belts, etc.).
Do not disconnect the (+) terminal while
the engine is running.
After every reconnection of the battery, switch
on the ignition and wait 1

minute before
starting to allow the electronic systems to be
initialised. If slight difficulties are experienced
after this, please contact a

CITROËN dealer or
a


qualified workshop. The positive battery terminal A is accessible
via an access cover located at the side of the
fusebox.
Make connections only to the points indicated
and illustrated above. If you fail to follow this
instruction there is the danger of a
short-circuit!

the backup battery B .

C. Earth on your vehicle
It is advisable to disconnect the negative
(-) terminal of the battery if the vehicle is
not to be used for a

period of more than
one month.
The description of the battery charging
procedure is given as an indication only.
If the battery has been disconnected for some
time, it may be necessary to reinitialise the
following functions:
-

t

he display parameters (date, time,
language, units of distance and
temperature),
-
r

adio stations,
-

c

entral locking.
Some settings are cleared and must be
reprogrammed; consult a


CITROËN dealer.
If your vehicle is fitted with a

tachograph or an
alarm, disconnection of the negative (-) terminal
of the battery (located under the floor on the
left-hand side, in the cab) is recommended
if the vehicle is not to be used for a

period of
more than 5

days.

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 maximum weights and towed loads for
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 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
towbar (can be dismantled with or without
a

tool).
GT W: Gross train weight.
High ambient temperatures may result
in a reduction in the per formance of
the vehicle to protect the engine. If the
ambient temperature is above 37°C, limit
the towed load.
Towing with a towing vehicle which is only
slightly laden may negatively affect its
handling.
Towing a
trailer increases the braking
distance.
When towing, never exceed the speed
of 62
mph (100 km/h) (obser ve the local
legislation in force). If the exterior temperature is high, it is
recommended that the engine be allowed
to idle for 1
to 2 minutes after the vehicle
comes to a stop, to facilitate its cooling.

Technical data

182
Weights and towed
loads (kg)
With load transfer, the braked trailer weight can
be increased, on condition that the equivalent
of this load is removed from the vehicle so that
the GTW is not exceeded. Warning: towing with
a lightly loaded towing vehicle may have an
adverse effect on its road holding.
The kerb weight is equal to the weight without
load + driver (75
kg) + fuel tank filled to 90%.
Hydraulic system
These precautions are mandator y for any
work on the hydraulic system. Before towing a trailer, check that:
-
t
he nose weight on the towbar ball does
not exceed the value (S) indicated on the
trailer's weight plate,
-
t
he maximum trailer weight is less than
the value indicated on the trailer's weight
plate and the Gross Vehicle Weight (GV W)
does not exceed the value indicated on the
vehicle's weight plate.
-
i
n the case of a self-supporting trailer,
the Gross Train Weight (GTW) must not
exceed the value indicated on the vehicle's
weight plate.
