Fiat 500X Owner's Handbook Manual page 166

Bird droppings must be washed off
immediately and thoroughly as the acid
they contain is particularly aggressive.
Windows
Use specific detergents and clean
cloths to prevent scratching or altering
the transparency.
IMPORTANT Wipe the rear window
inside gently with a cloth following the
direction of the filaments to avoid
damaging the heating device.
Headlights
Use a soft cloth soaked in water and
detergent for washing cars.
IMPORTANT Never use aromatic
substances (e.g. petrol) or ketones (e.g.
acetone) for cleaning the plastic lenses
of the headlights.
IMPORTANT When cleaning with a
pressure washer, keep the water jet at
least 20 cm away from the headlights.
Engine compartment
At the end of every winter, wash the
engine compartment thoroughly, taking
care not to aim the jet of water directly
at the electronic control units or at
the windscreen/rear window wiper
motors. Have this operation performed
at a specialised workshop.

IMPORTANT The washing should take
place with the engine cold and the
ignition device in the STOP position.
After the washing operation, make sure
that the various protections (e.g. rubber
caps and guards) have not been
removed or damaged.
WARNING
75) In order to preserve the aesthetic
appearance of the paint abrasive products
and/or polishes should not be used for
cleaning the vehicle.
76) Avoid washing with rollers and/or
brushes in washing stations. Wash the
vehicle only by hand using neutral pH
detergents; dry it with a wet chamois
leather. Abrasive products and/or polishes
should not be used for cleaning the vehicle.
Bird droppings must be washed off
immediately and thoroughly as the acid
they contain is particularly aggressive.
Avoid (if at all possible) parking the vehicle
under trees; remove vegetable resins
immediately as, when dried, it may only be
possible to remove them with abrasive
products and/or polishes, which is highly
inadvisable as they could alter the typical
opaqueness of the paint. Do not use pure
screen washer fluid for cleaning the
windscreen and rear window; dilute it min.
50% with water. Only use pure screen
washer fluid when strictly necessary due to
outside temperature conditions.
WARNING
7) Detergents cause water pollution. The
vehicle should be washed in areas
equipped for collecting and purifying the
liquid used in the washing process.
