Front headlights
Front headlights shall be washed with
soft cloth moistened with water and car
detergent.
IMPORTANT Cleaning headlight lens-
es with a dry cloth will damage the
headlights with lack of performance as
a consequence. Solvents mat the lens-
es with lack of performance as a con-
sequence.
IMPORTANT When washing the front
headlights with a water monitor noz-
zle keep at least 2 cm away from the
lenses.
Engine compartment
At the end of the winter the engine com-
partment should be carefully washed,
without directing the jet against electronic
control units. Contact a specialised work-
shop to have this done.
IMPORTANT The car should be
washed with the engine cold and the key
removed from the ignition device. After
washing make sure that the various pro-
tections (e.g. rubber caps and various cov-
ers) have not been damaged or removed.
