414 MAINTAINING YOUR VEHICLE WARNING! The air induction system (air cleaner, hoses, etc) can provide a measure of protection in the case of engine backfire. Do not remove the air induction system (air cleaner, hoses, etc) unless such removal is necessary for repair or maintenance. Make sure that no one is near the engine compartment before starting the vehicle with the air induction system (air cleaner, hoses, etc) removed. Failure to do so can result in serious personal injury. Engine Air Cleaner Filter (Diesel Engines) CAUTION! All air entering the engine intake must be filtered. The abrasive particles in unfiltered air will cause rapid wear to engine components. The air filter housing on your Diesel Ram is equipped with a Filter Minder™. This is an air flow restriction gauge that will indicate when the filter element needs to be replaced. Do not remove the top of the air filter housing to inspect the filter element on your diesel engine under normal operating conditions. NOTE: The air filter housing contains a Mass Air Flow sensor. This sensor is critical to proper engine operation and component longevity. Any damage or modification
