Air filter and passenger compartment filter
Refer to the servicing booklet for details of the replacement intervals for these components.
Depending on the environment (e.g. dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessary.
A clogged passenger compartment filter may have an adverse effect on the performance of the air conditioning system and generate undesirable odours.
