Maximum gradient-climbing capability

For good road surface conditions, the maximum gradient-climbing capability is 100%, which corresponds to an approach/departure angle of 45°. Note that the vehicle's gradient-climbing capability depends on the off-road conditions.
Accelerate carefully and make sure that the wheels do not spin when driving on steep terrain.

If the load on the front axle is reduced If the load on the front axle is reduced when pulling away on a steep uphill slope, the front wheels have a tendency to spin.
4ETS recognizes this and brakes the wheels accordingly. The rear wheel torque is increased, making it easier to drive off.
