Toyota Genuine Hybrid Battery Cooling Filter

The cooling of the hybrid battery is very important. With proper maintenance and care of the cooling system. However, the care of the hybrid battery filter is always overlooked. It should be changed together with the aircon filter as the same cabin air is being circulated to the hybrid filter. A clogged hybrid filter reduces the amount of cooled air in the hybrid battery and the hybrid battery temperature will rise. In some instances, an error warning message will be displayed on the speed meter.
