other components, a malfunction or fire may occur.
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 com- pressed 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 per-formance of the DC/DC converter and
cause a malfunction.
■To prevent damage to the vehicle
●Do not allow water or foreign matter to enter the air intake vent when the
cover is removed.
●Carefully handle the removed filter
so that it will not be damaged. If the filter is damaged, have it replaced with a new filter by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Make sure to reinstall the filter and cover to their original positions after cleaning.
●Do not install anything to the air intake vent other than the exclusive filter for this vehicle or use the vehi-
cle without the filter installed.
■If “Maintenance required for
DCDC converter cooling parts See Owner’s Manual” is shown on the multi-information display
If the vehicle is continuously driven with the warning message (indicating that the cooling performance/capac-
ity of the DC/DC converter may become limited) displayed, the DC/DC converter may malfunction. If

from the claw at the center of
the wiper blade. Pass the wiper
insert through the 3 claws so
that it sticks out from the stop-
per, and then pass the wiper
insert through the final remain-

claws are fitted in the grooves of
the wiper insert.
If the wiper blade claws are not fitted in
the grooves of the wiper insert, grasp the wiper insert and slide it back and forth multiple times to insert the claws
into the grooves.
Lightly lift up the center of the wiper insert to make the rubber easier to
slide.
