■Cleaning the air intake vent
●Dust in the air intake vent may inter- fere with the cooling of the DC/DC
converter. If the cooling perfor- mance/capacity of the DC/DC con-verter becomes limited, the 12-volt
battery may discharge. Inspect and clean the air intake vent periodically.
●Improper handling of the air intake vent cover and filter may result in damage to them. If you have any con-
cerns about cleaning the filter, contact any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
■If “Maintenance required for DCDC converter cooling parts See Owner’s Manual” is shown on the
multi-information display
●If this warning message is shown on
the multi-information display, remove the air intake vent cover and clean the filter. ( P.536)
●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 any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer.
WARNING
■When cleaning the air intake vent
●Do not use water or other liquids to
clean the air intake vent. If water is applied to the DC/DC converter or other components, a malfunction or
fire may occur.
●Before cleaning the air intake vent, make sure to turn the power switch
off to stop the hybrid system.
NOTICE
■When cleaning the air intake vent
