Practical information
7To clean instrument panels, touch screens
or other displays, wipe gently with a soft,
dry cloth. Do not use products (e.g. alcohol,
disinfectant) or soapy water directly on these
surfaces - risk of damage!
Bodywork
High-gloss paint
Do not use abrasive products, solvents,
petrol or oil to clean the bodywork.
Never use an abrasive sponge to clean
stubborn stains - risk of scratching the
paintwork!
Do not apply polish in strong sunshine, or to
plastic or rubber parts.
Use a soft cloth and soapy water or a pH
neutral product.
Gently wipe the bodywork with a clean
microfibre cloth.
Apply polish with the vehicle clean and dry.
Comply with the instructions for use stated on
the product.
Decals
(Depending on version)
Do not use a high-pressure washer to
clean the vehicle - risk of damaging or
detaching the decals!
Use a high-flow hose (temperature
between 25°C and 40°C).
Place the jet of water perpendicular to the
surface to be cleaned.
Rinse the vehicle with demineralised water.
Textile
The dashboard, door panels and seats may
contain parts made of textile material.
Maintenance
Do not use aggressive cleaning products
(e.g. alcohol, solvent or ammonia).
Do not use steam-cleaning systems - risk of
affecting the adhesion of the fabrics!
Remove dust from the textile parts
regularly with a dry cloth, soft brush or
vacuum cleaner
.
Rub down the
textile parts once per year with
a clean, damp cloth. After leaving overnight to
dry, brush with a soft-bristled brush.
Stain removal
Do not rub the stain or it may spread or
you may cause the substance to
penetrate the surface.
Act quickly by reducing the stain from its edges inwards.
Remove as much substance or solids as
possible using a spoon or spatula, and
remove
as much liquid as possible using
absorbent paper.
Product/Procedure to use depending
on the type of stain:
–

Grease, oil and ink: clean with a pH-neutral
detergent.
–


V

omit: clean with sparkling mineral water.
–

Blood: spread flour over the stain and allow
to dry; remove with a slightly damp cloth.
–


Mud: allow to dry and then remove with a
slightly damp cloth.
–


Cake, chocolate, ice cream: clean with
lukewarm water

.
–

Sugary and/or alcoholic drinks: clean with
lukewarm water

, or lemon juice if the stain is
persistent.
–

Hair gel, coffee, tomato sauce, vinegar:
clean with lukewarm water and lemon juice.
For solid substances, then use a soft brush or
vacuum cleaner

.
For liquid substances, then use a damp
microfibre cloth and then dry with another
cloth.
Leather
Leather is a natural product. Appropriate regular
care is essential for its durability.

172
In the event of a breakdown
after the lamps have been on for a few
minutes.
Never look too closely at the light beam
of LED technology lamps - risk of serious
eye injury!


The headlamps have polycarbonate lenses with a protective coating:
–

Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
–


Use a sponge and soapy water or a pH
neutral product.
–


When using a high-pressure washer on
persistent marks, do not keep the lance
directed towards the headlamps, lamps or
their edges for too long, so as not to damage
their protective coating and seals.
Changing a bulb must only be done with
the ignition off and after the headlamp /
lamp has been switched off for several
minutes - risk of serious burns!
Do not touch the bulb directly with your
fingers; use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
of the same type and specification. To avoid
lighting imbalance, replace the bulbs in pairs.
Refitting the lamp units
Perform the operations in the reverse
order to dismantling.
Light-emitting diode (LED)

Positive terminal with a quick-release
terminal.
(-) Negative terminal.
Starting using another
battery
If the vehicle's battery is flat, the engine can be
started using a backup battery (either external or
from another vehicle) and jump leads or using a
battery booster.
Never start the engine by connecting a
battery charger.
Never use a 24
V or higher battery booster.
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 electricity-consuming equipment
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are well away
from the engine’s moving parts (fan, belt,
etc.).
Do not disconnect the (+) terminal while the
engine is running.


► Lift the plastic cover on the (+) terminal, if the
vehicle has one.
►

Connect the red cable to the (+) terminal of
flat battery

A (at the metal elbow), then to the
(+) terminal of the backup battery
B or of the
booster.
►

Connect one end of the green or black cable
to the (-) terminal of the backup battery

B or of
the booster (or to an earth point on the assisting
vehicle).
►
Connect the other end of the green or black
cable to the (-) terminal of flat battery

A.
►

Start the engine on the assisting vehicle and
leave it running for a few minutes.
►


Operate the starter on the broken down
vehicle and let the engine run.
If the engine does not start immediately

, switch
off the ignition and wait a few moments before
trying again.
►

W
ait for it to return to idle.
►

Disconnect the jump leads in reverse order.
►


Refit the plastic cover to the (+) terminal, if
the vehicle has one.
►


Allow the engine to run for at least
30

minutes, with the vehicle stationary, so that
the battery reaches an adequate state of charge.
Driving immediately without having
reached a sufficient level of charge may
affect some of the vehicle's functions (e.g.
Stop & Start).
Charging the battery using a
battery charger
For optimum service life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances, it may be necessary to
charge the battery:

177
In the event of a breakdown
8– When using the vehicle mainly for short
journeys.
–

If the vehicle is to be taken off the road for
several weeks.
Contact a CITROËN dealer or a qualified
workshop.
To charge the vehicle's battery yourself, use only a charger compatible with
lead-acid batteries with a nominal voltage of
12

V.
Follow the instructions provided by the
manufacturer of the charger.
Never reverse polarities.
It is not necessary to disconnect the
battery.
►

Switch the ignition off.
►


Switch off all electrical consumers (audio
system, lighting, wipers, etc.).


► Switch off charger B before connecting
the cables to the battery, so as to avoid any
dangerous sparks.
► Ensure that the charger cables are in good
condition.
►

Lift the plastic cover on the (+) terminal, if the
vehicle has one.
►


Connect the cables of charger B

as follows:

off charger B

before disconnecting the cables
from battery A.
If this label is present, use only a 12 V
charger to avoid causing irreversible
damage to the electrical components.

Technical data
9Engine technical data and
towed loads
Engines
The engine characteristics are given in the
vehicle's registration document, as well as in
sales brochures.
Only the values available at the time of
publication are presented in the tables.
Contact a CITROËN dealer or a qualified
workshop to obtain missing values.
The maximum power corresponds to the value type-approved on a test bed, under
conditions defined by 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
the vehicle are indicated on the registration
document, as well as in sales brochures.
These values are also indicated 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 performance may be limited in
order to protect the engine. When the exterior
temperature is higher than 37°C, reduce the
towed weight.
Towing even with a lightly loaded vehicle can adversely affect its road holding.
Braking distances are increased when towing
a trailer.
When using a vehicle to tow, never exceed
a speed of 62 mph (100
km/h) (observe the
local legislation in force).
