If the figures differ, the lowest figure applies.
Vehicles with front-wheel drive:
Without a reduction in the gross combination weight, the clutch will be overloaded when driving at high elevations above 1,000 m with gradients greater than 8%. The excessive stress results in abnormal and premature wear on the clutch, which can damage it.
When driving at elevations above 1,000 m with only slight gradients of less than 8%, you are not required to reduce the gross vehicle weight of the vehicle combination.
The following values apply for driving at altitudes of 1000 m above sea level and for a minimum start-off gradeability of 12 %.
