may cause damage and malfunction.
NOTE
• If the filter is very dirty:
Dip the filter in lukewarm water with mild dish washing
detergent. Move it up and down as well as left and right to
loosen dirt. Rinse the filter with clean water and let it
air-dry.
IMPORTANT
• Do not use gasoline, thinner or similar chemicals to clean
the filter as damage to the filter may occur.
• It may also cause an unpleasant odor in the CABIN when
the system is used next.
