Double locking-what I learned today
Not exactly. Double locking will shut off Convenience Mode, instead of it taking about 20 minutes to time out by itself. That can help your battery to last longer.
US members who "double lock" their X150 will get a "beep beep" from the sounder. That double beep is an error message that means your car is not double locked. That's because double locking is not available on US market vehicles.
Double locking is not available on USA market vehicles because the National Highway Traffic Safety Administration (NHTSA) deemed it to be unsafe. Double locking is popular in Europe because it makes cars more difficult to steal. However, because the doors cannot be opened from the inside when double-locked, a small child, pet, or other passenger can be trapped inside and die from extreme heat.
When you double-lock your car, the beep-beep is an error message to tell you that your car is not double-locked. Visual confirmation that your car is locked is that your side mirrors automatically folded in, unless you disabled that feature or your car is not equipped with that feature.

Mr. October should have stayed with the Astros!
I was born in the Bronx and grew up in Queens.
Alas, I'm a long suffering Mets fan.
These were not my first thoughts either.
