Filter Inspection
The climate control air filter should be replaced according to the Maintenance Schedule. If the vehicle is operated in severely air-polluted cities or on dusty rough roads for a long period, it should be inspected more frequently and replaced earlier. When you replace the climate control air filter, replace it performing the following procedure, and be careful to avoid damaging other components.

1. With the glove box open, remove the stoppers on both sides to allow the glove box to hang freely on the hinges.

2. Remove the support rod (1).

3. Press and hold the lock (1) on both sides of the cover.
4. Pull out (2) the cover.

5. Replace the climate control air filter.
6. Reassemble in the reverse order of disassembly.
NOTICE
Install a new climate control air filter in the correct direction with the arrow symbol (↓) facing downwards, to prevent noise and reduce effectiveness.
