Before Driving Your Mazda
Fuel and Engine Exhaust Precautions
NOTE
After driving some distance and turning off the engine, the sound of a valve opening and
closing can be heard near the lower left part of the driver's seat or below the driver-side
door from the outside, however this does not indicate an abnormality. Your vehicle has a
self-checking device and it operates after turning off the engine.
