Brake system
Hill holder
The hill holder is part of the Telligent
®
brake system and assists with moving off on gradients. When the hill
holder is switched on, it remains in the ready state in forward and reverse gear even after an intermediate stop
or when the engine is switched off. The hill holder prevents the vehicle from rolling away on uphill and downhill
gradients and enables it to start off smoothly.
