🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the oil drain and filter

• Slide the drain pan under the oil pan area.
• If a lower splash shield is in the way, remove the fasteners using a 10mm socket and release any push-clips with a flat trim clip tool.
• Tip: Lay fasteners in a row to remember locations.

Step 2: Drain the old engine oil

• Remove the oil fill cap on top of the engine by hand (this helps it drain smoothly).
• Use a 15mm socket with a 3/8" drive ratchet to loosen the oil drain plug, then finish unscrewing by hand.
• Let the oil drain until it slows to an occasional drip (usually 5-10 minutes).

Step 3: Reinstall the drain plug

• Wipe the drain plug and the sealing surface with shop rags.
• Install a new oil drain plug gasket if your plug uses one.
• Thread the drain plug in by hand first to avoid cross-threading (damaging the threads).
• Tighten using a torque wrench and 15mm socket: Torque to 25 Nm (18 ft-lbs).

Step 4: Remove the old oil filter

• Move the drain pan under the oil filter area (the filter will spill oil when removed).
• Use an oil filter wrench (65mm 14-flute) (specialty) to loosen the filter, then spin it off by hand.
• Make sure the old rubber gasket comes off with the filter (a stuck gasket can cause a major leak).

Step 5: Install the new oil filter

• Put a thin film of fresh oil on the new filter’s rubber gasket (this helps it seal and come off next time).
• Spin the new filter on by hand until the gasket touches, then tighten an additional 3/4 turn by hand.
• If you must use a torque wrench with the filter wrench: Torque to 18 Nm (13 ft-lbs).

Step 6: Reinstall the splash shield (if removed)

• Reposition the shield and start all fasteners by hand.
• Tighten using a 10mm socket and 3/8" drive ratchet (snug only; don’t strip plastic).

Step 7: Refill with fresh oil

• Insert a funnel into the oil fill hole.
• Pour in 8 quarts of 0W-20 full synthetic dexos.
• Reinstall the oil fill cap by hand.

Step 8: Start, check for leaks, and verify the oil level

• Start the engine and let it idle for 30-60 seconds.
• Look underneath for leaks at the drain plug and oil filter using safety glasses.
• Shut the engine off and wait 5 minutes.
• Check the dipstick, wipe with a shop rag, reinsert, and recheck. Top off if needed.

Step 9: Reset the oil life monitor

• Turn ignition to ON (engine off).
• Use the steering wheel controls to navigate the Driver Information Center to the oil life screen.
• Press and hold SET/CLR until it resets to 100%.

✅ After Repair

• Confirm the dipstick level is within the crosshatch/safe range.
• Dispose of used oil and the old filter at an oil recycling drop-off (most parts stores accept it).
• Wipe any spilled oil off the skid shield and frame with shop rags.
