• Use only 0W-20 synthetic oil that meets Volvo specification.
• Do not overfill.

Step 8: Check the oil level

• Start the engine and let it idle for 30-60 seconds.
• Shut it off and wait a few minutes for the oil to settle.
• Check the level using the vehicle’s electronic oil level display.
• Top off in small amounts until the level reaches the correct range.

Step 9: Reinstall the splash shield

• Use the 3/8-inch ratchet to reinstall the lower engine cover.
• Make sure all fasteners are secured.
• Lower the vehicle from the jack stands.

Step 10: Reset the service reminder
