NOTICE
■If you remove the air cleaner:
Driving with the air filter removed may cause excessive engine wear due to dirt in
the air. Also a backfire could cause a fire in the engine compartment.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or
when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

■Checking interval
Inspect, clean and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, more frequent cleaning or
early replacement may be required. (For scheduled maintenance information,
please refer to the “Warranty and Services Guide/Owner's Manual Supplement/
Scheduled Maintenance”.)
■If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
■To prevent damage to the system
●When using the air conditioning system, make sure that a filter is always installed.
●When cleaning the filter, do not clean the filter with water.
■Cleaning method
If the filter is dirty, clean by blow-
ing compressed air through the

Hold the air gun 2 in. (5 cm)
from the filter and blow for
approximately 2 minutes at 72
psi (500 kPa, 5.0 kgf/cm
2 or
bar).
If it is not available, have the filter
