This is another instance where a G500 got stuck under testing. Following is the paragraph where it is mentioned:
The G500 is the only vehicle in the U.S. with three differential locks for maximum tractability in low-traction situations. To reduce wheelspin in extremely low-traction situations, the center and rear differential locks can be engaged anytime that the G-Class is off-pavement. In the unlikely event the vehicle gets stuck (we got it stuck at the press intro), the front differential can also be engaged for maximum traction. Mercedes advises, though, that the differentials should not be locked when you're on pavement because handling is affected.
G500, G stands for Gee I got stuck again, Gee I spent too much on this, Gee my buthole is sore, Gee tampons work there too?! Gee vagisil is unisex, I had no idea. Gee I can just put a piece of gum on my dick for protection or maybe a thimble!
