■ Cleaning the air intake vent
● Dust in the air intake vent may
interfere with the cooling of the
DC/DC converter. If the cooling
performance/capacity of the
DC/DC converter becomes lim-
ited, the 12-volt battery may dis-
charge. 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
concerns about cleaning the filter,
contact your Toyota dealer.
■ 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.486)
● 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 min-
utes after the hybrid system is
started until the warning message
disappears. If the warning mes-
sage does not disappear, have
the vehicle inspected by your
Toyota dealer.
WARNING
■ When cleaning the air intake
vent
● Do not use water or other liq-
uids 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
When cleaning the air intake vent,
make sure to only use a vacuum
to suck out dust and clogs. If a
compressed air blow gun, etc. is
used to blow out dust and clogs,
the dust or clogs may be pushed
into the air intake vent, which may
affect the performance of the
DC/DC converter and cause a
malfunction.
