Is the 4WD Lock On or Off?

[DelSamantha]

The 4WD lock button is pressed to engage, meaning it locks the central differential. In other words, the 4WD lock button is not simply an on/off switch but rather a lock switch for the central differential. Pressing it activates the differential lock. When the vehicle is in a situation where it needs to escape, the front and rear axles can distribute driving force, preventing all power from transferring to a slipping axle. Additional Information: 1. The main function of engaging the 4WD lock is equivalent to activating the 4WD mode, allowing switching between ice, sand, and mud 4WD modes. The 4WD lock is primarily used for the vehicle's escape mode during driving, generally needed when traversing complex road conditions. It can provide up to 50% driving force to the rear wheels. 2. When the vehicle is in escape mode, locking the central differential can enhance the vehicle's escape performance. Of course, under normal circumstances, this switch is not needed. However, when driving on steep mountain roads, slippery surfaces, or through large puddles, this switch can come in handy.
