What do the three locks of the Big G mean?

[MacWillow]

The three locks of the Big G refer to the central differential lock, front axle differential lock, and rear axle differential lock. The specific details are as follows: 1. When the car is driving in full-time four-wheel drive mode, activating the central differential lock is suitable for roads with gravel or slight bumps and slopes, as well as sections where single-wheel slippage is likely to occur in the front or rear wheels. The rear axle differential lock is also suitable for roads with many rocks or severe bumps. When the rear axle differential lock is engaged, the rear wheels still maintain traction. 2. After activating the front axle differential lock, all wheels on the car have the same traction, making it more suitable for extremely harsh road conditions or situations where all wheels on the same side lose traction. This mode is ideal for desert driving or snow escape.
