Hyundai Sonata: Owner Maintenance / Owner Maintenance Schedule

When you stop for fuel:

• Check the engine oil level.
• Check coolant level in the engine coolant reservoir.
• Check the windshield washer fluid level.
• Check for low or under-inflated tires.

WARNING

Be careful when checking your engine coolant level when the engine is hot. This may result in coolant being blown out of the opening and cause serious burns and other injuries.

While operating your vehicle:

• Note any changes in the sound of the exhaust or any smell of exhaust fumes in the vehicle.
• Check for vibrations in the steering wheel. Notice if there is any increased steering effort or looseness in the steering wheel, or change in its straight-ahead position.
• Notice if your vehicle constantly turns slightly or "pulls" to one side when traveling on smooth, level road.
• When stopping, listen and check for unusual sounds, pulling to one side, increased brake pedal travel or "hard-to-push" brake pedal.
• If any slipping or changes in the operation of your transmission occurs, check the transmission fluid level.
• Check the automatic transmission /ecoshift dual clutch transmission P (Park) function.
• Check the parking brake.
