■ If the vehicle is not used for a long time
● The 12-volt battery may discharge. In this event, charge the 12-volt battery.
In order to prevent the hybrid battery (traction battery) from becoming extremely low
in charge, charge the hybrid battery (traction battery) from external power source or
start the hybrid system at least once every 2 or 3 months, and turn the power switch
off after the gasoline engine has stopped automatically.
If the gasoline engine does not start up even after approximately 10 seconds have
passed since the "READY" indicator came on, the power switch can be turned to off
without any further action.
● When the vehicle is left with the AC charging cable connected, the electricity con-
sumption amount of the 12-volt battery increases due to controls, such as the system
checking, operating. When the AC charging cable is not needed, immediately remove
it from the vehicle.
DC/DC converter air intake vent
There is an air intake vent under the rear seat
for cooling the DC/DC converter. Blocking the
air intake vent may prevent the plug-in hybrid
system from operating properly.
NOTICE
Observe the following precautions regarding the 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, periodically clean it with a
vacuum 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.
● 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.
