Maintenance and care

Checking interval
Inspect, clean and replace the air conditioning filter according to the mainte-
nance schedule. In dusty areas or areas with heavy traffic flow, more fre-
quent cleaning or early replacement may be required. (For scheduled
maintenance information, please refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.)
■ If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.

filter and replace it with a new
one.

■ After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. ( P. 580)
● If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
■ If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.

Add engine coolant if required.

gency if engine coolant is
unavailable. ( P. 650)
Have the vehicle checked at your nearest Toyota dealer as soon as
possible.
