Filthy Air Filter
If you drive in dusty conditions, it is better to clean the air filter more often than specified

4) Clean The Filters – A clogged air filter would hamper the engine’s performance and will take a toll on driveability and fuel efficiency as well. It is best to clean the air filter and cabin AC filter every 5000 kms.

3) Air Conditioner – Proper cooling from the AC and flow of air through the vents can be checked in a couple of minutes. One should also clean the cabin AC filter and check if the compressor is kicking in normally. Ideally, an AC service should be carried out every two years by a dedicated AC mechanic.
