When washing the vehicle, never use a  
water hose or high-pressure jet to clean  
the interior.  
Liquids carried in cups or other open  
containers can spill, presenting a risk of  
damage to the instruments and controls and  
the controls located on the centre console. Be  
vigilant!  
To 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!  
the engine compartment - risk of  
damaging the electrical components!  
Do not wash the vehicle in bright sunshine or  
extremely cold conditions.  
Decals  
(Depending on version)  
Do not use a high-pressure washer to  
clean the vehicle - risk of damaging or  
detaching the decals!  
When washing the vehicle in an  
automatic roller-brush car wash, be sure  
to lock the doors and, depending on version,  
move the electronic key away.  
When using a pressure washer, keep the jet  
nozzle at a minimum distance of 30 cm from  
the vehicle (particularly when cleaning areas  
containing chipped paint, sensors or seals).  
Promptly clean up any stains containing  
chemicals liable to damage the vehicle's  
paintwork (including tree resin, bird

droppings, insect secretions, pollen and tar).  
Depending on the environment, clean the  
vehicle frequently to remove salty deposits  
(in coastal areas), soot (in industrial areas)  
and mud/salts (in wet or cold areas). These  
substances can be highly corrosive.  
Contact a CITROËN dealer or a qualified  
workshop for advice on removing stubborn  
stains requiring special products (such as tar  
or insect removers).  
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!  
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!  
Do not apply polish in strong sunshine, or to  
plastic or rubber parts.  
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.  
Use a soft cloth and soapy water or a pH  
neutral product.  
Gently wipe the bodywork with a clean  
microfibre cloth.  
Preferably, have paint touch-ups performed  
by a CITROËN dealer or a qualified  
workshop.  
Apply polish with the vehicle clean and dry.

Leather  
Leather is a natural product. Appropriate regular  
care is essential for its durability.  
Act quickly by reducing the stain from its  
edges inwards.  
It must be protected and nourished using a  
specific leather product, to keep it supple and  
preserve its original appearance.

possible using a spoon or spatula, and  
remove as much liquid as possible using  
absorbent paper.  
Do not clean leather using unsuitable  
cleaning agents such as solvents,

leather, take care not to damage the other  
materials with the specific leather product.

Before cleaning greasy stains or liquids,  
quickly mop up any surplus.  
Before cleaning, wipe off any residues liable  
to scuff the leather, using a cloth that has  
been dampened with demineralised water  
and thoroughly wrung out.
