When can I activate the differential lock so that this does not possibly damage the motor vehicle?

The proper activation of a differential lock is crucial for maintaining vehicle stability and preventing damage. In this context, activating the differential lock is appropriate when the vehicle is stationary or moving at walking speed.

When the vehicle is stationary, engaging the differential lock helps prevent wheel spin and aids in traction when the vehicle is stationary. Similarly, at walking speed, the differential lock ensures better traction without risking damage because the forces exerted on the vehicle's drivetrain are minimal.

However, engaging the lock while understeering in a bend can lead to mechanical strain and potential damage. Understeering typically means the vehicle can't turn as sharply as intended, causing the wheels to lose traction. Engaging the lock in such a scenario might exacerbate the situation, risking damage or loss of control.

Understanding when to use the differential lock according to these parameters is essential for safety and the longevity of the vehicle, as per German traffic regulations.
