NOTICE
■Notice about fuel
●For plug-in hybrid vehicles, fuel
may remain in the tank for a long time and undergo changes in qual -
ity depending on the how the vehi -
cle is used. Refuel at least 20 L (5.3 gal., 4.4 Imp.gal. ) of fuel every 12
months (refuel a tot al of at least 20
L [5.3 gal., 4.4 Imp.gal.] over a 12-
month period), as this may affect components of the fuel system or
the gasoline engine.
●If the vehicle has not been refueled
for a certain amount of time and it is
possible that the quality of the fuel remaining in the tank has changed,
“No New Fuel has been Added
Recently Please refuel” is displayed on the multi-information display
when the power switch is turned to
ON. If the message is displayed, refuel the vehicle immediately.

vent
NOTICE
■DC/DC converter air intake vent
●Make sure not to block the air
intake vent with anything, such as a seat cover, plastic cover, or lug -
gage. Blocking the air intake vent
may prevent the plug-in hybrid sys - tem from operating properly.
●When dust etc. has accumulated in
the air intake ven t, clean it with a vacuum cleaner to prevent the vent
from clogging.
●Do not wet or a llow foreign sub-
stances to enter the air vent as this
may cause a shor t circuit and dam- age the DC/DC converter.
●Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the
DC/DC converter, the converter may be damaged. Have the vehicle
inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
●A filter is installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning
the air intake vent, filter cleaning or replacement is recommended.
When cleaning the filter, refer to
P.536.
●If “Maintenance required for DCDC
converter cooling parts See Owner’s Manual” is shown on the
