OBSERVATION AND COMMUNICATION
Observation and communication are an important part of a preventive maintenance program. The driver needs to put his/her senses to work.
Listen for unusual or abnormal equipment sounds such as rattles, squeaks and hisses.
Smell for unusual odors such as burning rubber or hot oil.
Feel for changes in the vehicle's response, including steering, braking and shifting.
Observe all vehicle components carefully during routine inspections. Look for defects.
