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 Toy ota 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-informatio n 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 syst em is started until the warning message disappears. If
