■Cleaning the air intake vent
●Dust in the air intake vent may inter-
fere with the cooling of the DC/DC
converter. If the cooling perfor-
mance/capacity of the DC/DC con-
verter becomes limited, the 12-volt
battery may discharge. 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 con-
cerns about cleaning the filter, contact
any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
■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.504)
●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 minutes
after the hybrid system is started until
the warning message disappears. If

WARNING
■When cleaning the air intake vent
●Before cleaning the air intake vent,
make sure to turn the power switch off to stop the hybrid system.
●Do not use water or other liquids to clean the air intake vent. If water is applied to the DC/DC converter or
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
the warning message is displayed, clean the air intake vent immediately.

5468-2. Steps to take in an emergency
shown on the multi-information dis-
play, the vehicle may have run out of fuel. Stop the vehicle in a safe place and, if the fuel level is low, refuel the
vehicle. • “Hybrid System Stopped”• “Engine Stopped”
●If “Maintenance required for DCDC converter cooling parts See Owner’s
Manual” is shown, the filter may be clogged, the air intake vent may be blocked, or there may be a gap in the
duct. Therefore, perform the following correction procedure.• If the air intake vent or filter of the
DC/DC converter are dirty, perform the procedures on P.504 to clean them.
• If the warning message is shown when the air intake vent and filter of the DC/DC converter are not dirty,

The message may be shown when driv- ing under severe operating conditions. (For example, when driving up a long
steep hill or driving up a steep hill in reverse.)
Coping method: P.578
■If “Traction Battery Needs to be
Protected Refrain from the Use of N Position” is shown
This message may be displayed when
the shift lever is in N.
As the hybrid battery (traction battery) cannot be charged when the shift lever is in N, shift the shift lever to P when the
vehicle is stopped.
■If “Traction Battery Needs to be Protected Shift into P to Restart” is shown
This message is displayed when the hybrid battery (traction battery) charge has become extremely low because the
shift lever has been left in N for a certain amount of time.
