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 Traction 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. 434)

●

After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer displayed.
