While operating the vehicle:
- Pay attention to any change in exhaust sound or any smell of exhaust gas in the vehicle.
- Check for vibration in the steering wheel. Note any increase in steering effort, play in the steering wheel, or change in its straight-ahead position.
- Note if the vehicle constantly turns slightly or "pulls" to one side when driving on a smooth, level road.
- When stopping, listen for unusual noises and check for pulling to one side, increased brake pedal travel, or a "hard" brake pedal.
- If any slipping or changes in transmission operation occur, check the transmission fluid level.
