If you order air filters for the engine, they come as a pair. Similarly I would expect the activated charcoal filters to come as a pair. The paper a/c filter, located over the battery, is shown here when unclipped from the intake duct (on my RHD CLK)Yesterday, I ordered one (1) carbon filter for under the glove box. But I see from the pictures you posted that it seems to require two (2) filters? Is that correct? There are a total of three (3) activated charcoal filters for the cabin air?
The one above the battery is NOT a carbon filter - it's just paper as my image shows. Under the glove box are a pair of activated carbon filters.Let me boil it down:
Are there two (2) activated charcoal cabin air filters under the glove compartment IN ADDITION to the carbon cabin air filter above the battery in the engine compartment?
Is this the button that would close all the windows?That is correct - only the models with the "full dual-zone" A/C have the charcoal filter. If all you have is dual temp control, but not dual airflow control, you don't have the charcoal filters. I believe the full dual-zone A/C system came standard on V8's but optional on V6 models (at least in the USA). Oh, and you will have a button to activate the charcoal filter. If you look at Keyhole's picture above, it's the button just to the left of the LCD panel that has the symbol ">|>" on it.
No - you are getting confused with holding down the 'Recirculate' button. That closes all windows & the sunroof - in case you are following a smelly vehicle... It's all in the Owner's Manual!Is this the button that would close all the windows?
Only if you have the filter ON/OFF switch.My car does have the dual-temp control. So, I do have the charcoal filter then.
