How to Use the Three Differential Locks on the G-Class?

Each differential lock is used at different times. Differential locks are not needed under the following conditions: driving on straight roads or ordinary roads, where the G-Class is in full-time four-wheel drive mode. Below are the scenarios for activating the three differential locks: 1. Activate Differential Lock 1 (Central Differential Lock): This ensures the front and rear axles rotate at the same speed, suitable for roads with gravel or minor bumps, or slight slopes where single-wheel slippage (either front or rear) may occur. However, it is not suitable for cross-axle conditions. 2. Activate Differential Lock 2 (Rear Differential Lock): This ensures both rear wheels and the front axle rotate at the same speed, suitable for situations where only one rear wheel maintains traction, such as encountering large rocks or severely uneven roads. 3. Activate Differential Lock 3 (Front Differential Lock): This ensures all wheels receive equal power, suitable for extremely harsh conditions where all wheels on one side lose traction or only any single wheel has traction. It is ideal for desert driving or escaping snow traps.
