Checking interval
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement
may be required. (For scheduled maintenance information, please refer to
the “Warranty and Maintenance Booklet” [except for Canada] or “Warranty
and Service Booklet” [for Canada].)
■ If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
CAUTION
■When removing the glove box
Do not forcibly pull the glove box. Otherwise, the lower claws or the lower
claw engagement points may be deformed, making it difficult to reinstall or
close the glove box.
■ When using the air conditioning system
Make sure that a filter is always installed.
Using the air conditioning system without a filter may cause damage to the
system.
