traffic or dusty areas, the air intake vent may need to be cleaned more regu\
-
larly. For details, refer to the “Scheduled Maintenance Guide” or “Own\
er’s
Manual Supplement”.
■ Cleaning the air intake vent
●Dust in the air intake vent may interfere with the cooling of the hybrid battery

tance that the vehicle can be driven using the electric motor (traction motor)
may be reduced and the fuel consumption may increase. Inspect and clean
the air intake vent periodically.
● Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter, contact your
Toyota dealer.

the air intake vent cover and clean the filter. ( →P. 637)
● After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer shown.
It may take approximately 20 minutes after the hybrid system is started until
the warning message disappears. If the warning message does not disap-
pear, have the vehicle inspected by your Toyota dealer.

applied to the hybrid battery (traction battery) or other components, a mal-
function or fire may occur.
