Maintenance and care
■Changing interval for the front air conditioning filter
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, such as inner city or
desert areas, early replacement may be required. (For scheduled mainte -
nance information, please refer to the "Owner's Manual Supplement/Sched-
uled Maintenance".)
■If air flow decreases dramatically
The filter may be blocked. Check the filter and replace if necessary.
CAUTION
■Air purifier precautions
●Do not look into the xenon tube or directly expose your skin to the light in the
tube's light. The tube emits less than 300nm of ultraviolet light, however some
people may experience symptoms such as sore eyes, vision trouble, skin inflam-

also the possibility of causing a malfunction.
