The air entering the car from the street is cleaned of dirt and pollen particles in the cabin air filter, located in the climate unit housing.
The air filter element must be replaced in accordance with the terms of preventive maintenance (see «Replacing the cabin air filter»).
Exhaust ventilation is carried out through grilles, which are installed on the side linings of the luggage compartment.
Helpful Hint: When placing loads in the luggage compartment, try not to obstruct the ventilation grilles whenever possible. Leave a small gap between the load and the facing panels. Efficient operation of the exhaust ventilation improves the temperature in the cabin and reduces the formation of condensation on the windows.
From the side of the street, the exhaust ventilation openings are closed by deflectors with petal flaps, which are installed in the rear part of the body, in the cavity of the rear bumper.
Note: If there is a smell of exhaust gases in the car interior, check the operation and tightness of the flap valves of the deflectors (view of the valve block from the trunk side with the trunk lining removed).
