Maintenance and care
■Scheduled maintenance of the air intake vent is necessary when
In some situations such as when the vehicle is used frequently or in heavy
traffic or dusty areas, the air intake vent may need to be cleaned more regu\
-
larly. For details, refer to “Schedule maintenance guide” or “Owner’s Manual
Supplement”.
■ Cleaning the air intake vent
●Dust in the air intake vent may interfere with the cooling of the hybrid battery
(traction battery). If the hybrid battery (traction battery) overheats, the dis-
tance that the vehicle can be driven using the electric motor (traction motor)
may be reduced and the fuel consumption may increase.
Inspect and clean the air intake vent periodically.
● Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter, contact your
Toyota dealer.
■ If “Maintenance Required for Tracti on Battery Cooling Parts See Owner’s
Manual” is displayed on the multi-information display
● If this warning message is displayed on the multi-information display,
remove the air intake vent cover and clean the filter. (→P. 450)
● After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer displayed.
After the hybrid system is started, it may be necessary to drive the vehicle
up to approximately 20 minutes befor e the warning message disappears. If
the warning message does not disappear after driving for appropriately 20
minutes, have the vehicle inspected by your Toyota dealer.
WARNING
■When cleaning the air intake vent
Do not use water or other liquids to clean the air intake vent. If water is
applied to the hybrid battery (traction battery) or other components, a mal-
function or fire may occur.

● 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 your Toyota
dealer.
● 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 vehicle without the filter installed.
■ If “Maintenance Required for Traction Battery Cooling Parts See
Owner’s Manual” is displayed on the multi-information display
If the vehicle is continuously driven with the warning message displayed,
the hybrid battery (traction battery) may overheat, possibly causing a mal-
function. If the warning message is displayed, clean the air intake vent
immediately.
When cleaning the air intake vent, make
sure to only use a vacuum to suck out
dust and clogs. If a compressed 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 performance of the hybrid battery
(traction battery) and cause a malfunc-
tion.
