REPLACEMENT TIMING
Replacement of the two air conditioner filters is recommended on a regular interval depending on the driving
conditions. Refer toMA-8, "
PERIODIC MAINTENANCE". It may also be necessary to replace the two air con-
ditioner filters as part of a component replacement if the air conditioner filters are damaged.
REPLACEMENT PROCEDURE
1. Remove the RH lower dash side finisher. Refer toEI-33, "BODY SIDE TRIM".
2. Remove the front pillar lower finisher. Refer toEI-33, "
BODY SIDE TRIM".
3. Remove the lower glove box.
a. Remove the two lower glove box lower screws.
