Oil and Filter Replacement: Oil replacement along with a filter replacement is utterly important for impurities from entering the engine.

• Spark Plug Replacement: Plugs are responsible for efficient combustion, and their timely replacement prevents misfires and ensures better fuel economy.
• Brake System Inspection: Replacing brake pads, cleaning rotors and checking fluid levels ensures better braking.
• Tire Inspection and Rotation: Periodic tire rotation ensures even wear, extending tire life and improving handling.

In most models, the A3 service is required typically every 10,000 miles (or every year), whichever comes first.
