WARNING
■ While driving
The driver should pay extra attention to pedestrians when the v ehicle is
powered only by the electric motor (traction motor). As there is no engine
noise, the pedestrians may misjudge the vehicle’s movement. Even though
the vehicle is equipped with the Acoustic Vehicle Alerting Syst em, drive with
care as pedestrians in the vicinity may still not notice the ve hicle if the sur-
rounding area is noisy.
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 luggage. Blocking the air intake vent may prevent
the plug-in hybrid system from operating properly.
● When dust etc. has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not wet or allow foreign substances to enter the air vent as this may
cause a short circuit and damage the DC/DC converter.
● Do not carry large amounts of water such as water cooler bottle s in the
vehicle. If water spills onto the DC/DC converter, the converte r may be
damaged. Have the vehicle inspected by your Toyota dealer.
● A filter is installed to the air intake vent. When the filter r emains noticeably
dirty even after cleaning the air intake vent, filter cleaning or replacement
is recommended. When cleaning the filter, refer to “OWNER’S MAN UAL”.
● If “Maintenance required for DCDC converter cooling parts See Owner’s
Manual” is shown on the multi-information display, the air intake vent and
filter may be clogged. Refer to “OWNER’S MANUAL” for information on
how to clean the air intake vent.
