Function
The cabin filter for the high voltage traction battery is located below the left side of the rear seat.
The air from the cabin is drawn in by the traction battery cooling fan to cool the high voltage battery - allowing it to remain and operate at its optimum temperature.
This filter prevents any unnecessary build-up of dirt and dust from the interior finding its way into the battery cooling fan - ensuring the reliability of the high voltage battery cooling fan motor.
Cause of failure
If the vehicle is used in an area with heavy traffic or excessive dust, or if the rear seat is used frequently, the high voltage traction battery cabin intake filter may become overloaded with dust and debris.
In the event of an issue, the message ‘’Maintenance required for traction battery cooling parts see owner‘s manual“ is displayed on the multi-information display - informing the driver that the traction battery cooling system requires attention.
The vehicle manufacturer recommends that this filter is visually inspected for dirt or dust every 15,000 km (10,000 miles) - and replaced if necessary - or replaced every 30,000 km (20,000 miles) as part of the vehicle’s regular maintenance schedule.
If the vehicle is operated under severe conditions, it is recommended to replace this filter every 15,000km (10,000 miles).
Note: using a suitable diagnostic tool, any trouble codes should be cleared to reset the hybrid cooling system learning values.
