MAN EasyStart
The automated MAN TipMatic® shift system incorporates the setting-off aid MAN EasyStart which means setting off on gradients is much easier and therefore safer. When active, the stationary vehicle is prevented from rolling back for up to 2 seconds by maintaining the brake pressure which was last applied by the brake pedal once the brake pedal is released and the parking brake is not applied. When setting off, the service brake is automatically released as soon as the required engine torque is available. In situations where setting off is difficult, the automatic MAN EasyStart feature makes life significantly easier for the driver. MAN EasyStart does away with having to apply the parking brake which uses a lot of pressurized air, e.g. during a hill start or in stop-and-go traffic. Furthermore, as the vehicle will not roll back against the direction of travel during a hill start, there is no danger of rolling into any vehicle behind your own vehicle. Additionally, there is less wear on clutch and gearbox which reduces service costs.
