Is there a break in period?

Just wanted to see if there is anything I should or should not be doing for the first 1k miles on a 2020 X5?

Thanks!

"Doing an engine break-in used to be a standard procedure with new cars. And it's still the case that you should avoid running the engine at high RPM for the first 1,300 miles. Experts recommend a maximum 3,500 rpm and 90 mph in diesel models and 4,500 rpm and 100 mph in gas models. This will give the engine and transmission sufficient time to adjust to each other. Once you've reached the 1,300-mile mark, you can gradually increase your speed and your engine's RPM. In particular, avoid to put too much strain on a cold engine. However, that's true not just when breaking in a new car but for the whole life cycle of your car. Likewise, never turn off an engine that has been running hard. Allow it to cool down by driving a few miles at a gentle pace.


During the new car break-in period, take note of the following tips:

For the first 200 miles, new tires will not yet provide full grip. This is because a release lubricant used in the manufacturing process has to be worn away from the tire surface. Adjust your driving accordingly to prevent accidents.
Similarly, the brakes won't become fully effective for the first 300 miles as the brake pads and discs will need to adjust to one other. You should therefore drive cautiously.
The shock absorbers and springs will also need some time to become fully effective. That's why you should not push your new car to its limits during the first 1,000 miles or so.
While many engine break-in tips also apply to modern engines, one compulsory rule for new cars has disappeared, as it's no longer necessary to change the engine oil after the first 1,000 miles. You should, however, also keep these break-in practices in mind when replacing individual components later on."

Owners manual says for the first 1,200 miles, keep the car less than 100MPH and less than 4,500 RPM.
