How do I check the engine oil level in a BMW 6 Series?

I recently purchased a BMW 6 Series and I'm not sure how to check the engine oil level. Can you provide step-by-step instructions?

To check the engine oil level in your BMW 6 Series, follow these steps:
1. Park the car on a level surface and wait for the engine to cool down.
2. Open the hood and locate the engine oil dipstick, which is usually labeled in yellow.
3. Pull out the dipstick and wipe it clean with a cloth or paper towel.
4. Reinsert the dipstick all the way and then pull it out again.
5. Look at the markings on the dipstick to determine the oil level. It should be between the two marks.
If the oil level is low, add the recommended type of oil in small increments and recheck the level until it reaches the optimal range.

Another way to check the engine oil level is using the onboard computer in your BMW 6 Series. Here's how:
1. Turn on the ignition and press the BC button on your steering wheel until you see the oil temperature display.
2. Press and hold the BC button until the oil level screen appears.
3. Wait for the message 'Engine oil OK' to appear, indicating the oil level is within the optimal range.
If the message displays 'Oil level too low,' it's time to add oil.

It's always a good idea to check the engine oil level regularly to ensure the longevity and performance of your BMW 6 Series. I recommend checking it every month or before embarking on a long journey. If you notice a significant decrease in the oil level, it could be a sign of a leak or other issue that should be inspected by a mechanic.
