Plenum chamber
The plenum chamber is located in the engine compartment between windshield and engine, under a perforated cover. Outside air is taken into the vehicle interior from the plenum chamber via the climate control system.
Regularly remove leaves and other loose objects from the plenum chamber cover by hand or with a vacuum cleaner.
